== Using Symbolic Package in Octave ==

* Visit http://octave.sourceforge.net/index.html
* Download symbolic-1.0.9.tar.gz

* In Ubuntu, using the Ubuntu Software Center, I installed GiNac and CLN related software and symbolic package for Octave. But it did not properly installed.

* After extracting files from symbolic-1.0.9.tar.gz, I followed the following steps.
 ./configure 
 ./make 
 ./make INSTALL_PATH=/usr/share/octave/packages/3.2/symbolic-1.0.9 

* While doing this, I got an error message related to mkoctfile. So, I used the following command: sudo apt-get install ocatve3.2-headers. Then I was able to install the symbolic packages in the Ubuntu.

== Read some tutorials about symbolic computation ==

== Tech News: 2026-09 ==

&lt;section begin=&quot;technews-2026-W09&quot;/&gt;&lt;div class=&quot;plainlinks&quot;&gt;
Latest '''[[m:Special:MyLanguage/Tech/News|tech news]]''' from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. [[m:Special:MyLanguage/Tech/News/2026/09|Translations]] are available.

'''Weekly highlight'''
* [[mw:Special:MyLanguage/Edit check/Reference Check|Reference Check]] has been deployed to English Wikipedia, completing its rollout across all Wikipedias. The feature prompts newcomers to add a citation before publishing new content, helping reduce common citation-related reverts and improve verifiability. In A/B testing, the impact was substantial: newcomers shown Reference Check were approximately 2.2 times more likely to include a reference on desktop and about 17.5 times more likely on mobile web. [https://analytics.wikimedia.org/published/reports/editing/reference_check_ab_test_report_final_2025.html]
'''Updates for editors'''
* The [[mw:Special:MyLanguage/Extension:InterwikiSorting|InterwikiSorting extension]], which allowed for the [[m:Special:MyLanguage/Interwiki sorting order|sorting of interwiki links]], has been undeployed from Wikipedia. As a result, editors who had enabled interwiki link sorting in non-compact mode (full list format) will now see links reordered. The links moving forward will be listed in the alphabetical order of language code. [https://phabricator.wikimedia.org/T253764]
* Later this week, people who are editing a page-section using the mobile visual editor, will notice a new &quot;Edit full page&quot; button. When tapped, you will be able to edit the entire article.

* [[mw:Special:MyLanguage/Readers/Reader Experience|The Reader Experience team]] is inviting editors to assess whether dark mode should still be considered &quot;beta&quot; on their wiki, based on their experience of how well it functions on desktop and mobile. If the feature is deemed mature, editors can update the interface messages in &lt;code dir=ltr&gt;MediaWiki:skin-theme-description&lt;/code&gt; and &lt;code dir=ltr&gt;MediaWiki:Vector-night-mode-beta-tag&lt;/code&gt; to indicate that dark mode is ready and no longer considered beta.
* The improved [[mw:Wikimedia_Apps/Team/iOS/Activity_Tab|Activity tab]] which displays user-insights is now available to all users of the Wikipedia iOS app (version 7.9.0 and later). Following earlier A/B testing that showed higher account creation among users with access to the feature, it has been rolled out to 100% of users along with some updates. The Activity tab now shows your edited articles in the timeline, offers editing impact insights like contribution counts and article view trends, and customization options to improve in-app experience for users.

'''Updates for technical contributors'''
* The [[m:Special:GlobalWatchlist|Global Watchlist]] lets you view your watchlists from multiple wikis on one page. The [[mw:Special:MyLanguage/Extension:GlobalWatchlist|extension]] that makes this possible continues to improve. The latest upgrade is the inclusion of a [[mw:Extension:GlobalWatchlist#hook|new hook]], &lt;code dir=ltr&gt;ext.globalwatchlist.rebuild&lt;/code&gt;, which fires after each watchlist rebuild. This allows you to run gadgets and user scripts for the Special page. [https://phabricator.wikimedia.org/T275159]

'''Weekly highlight'''
* Wikipedia 25 [[m:Special:MyLanguage/Wikipedia 25/Easter egg experiments|Birthday mode]] is now live on Betawi, Breton, Chinese, Czech, Dutch, English, French, Gorontalo, Indonesian, Italian, Luxembourgish, Madurese, Sicilian, Spanish, Thai, and Vietnamese Wikipedias! This limited-time campaign feature celebrates 25 years of Wikipedia with a birthday mascot, Baby Globe. When turned on, Baby Globe is shown on [[m:Special:MyLanguage/Wikipedia 25/Easter egg experiments/article configuration|~2,500 articles]], waiting to be discovered by readers. Communities can choose to turn Birthday mode on by getting consensus from their community and asking an admin to enable the feature and customize it via [[m:Special:MyLanguage/Wikipedia 25/Easter egg experiments#Community Configuration Demo|community configuration]] on the local wiki.

'''Updates for editors'''
* [[:m:Special:MyLanguage/WMDE Technical Wishes/Sub-referencing|Sub-referencing]], a new feature to re-use references with different details has been released to Swedish Wikipedia, Polish Wikipedia and [[:phab:T418209|a couple of other wikis]]. You can [[:m:Special:MyLanguage/WMDE Technical Wishes/Sub-referencing#test|try the feature]] on these projects or on testwiki and [https://en.wikipedia.beta.wmcloud.org/wiki/Sub-referencing betawiki]. Learnings from the first pilot wiki German Wikipedia have been [[:m:Special:MyLanguage/WMDE Technical Wishes/Sub-referencing/Learnings|published in a report]]. Reach out to the Wikimedia Deutschland team if you are [[:m:Talk:WMDE Technical Wishes/Sub-referencing#Pilot wikis|interested in becoming a pilot wiki]].
* [[mw:Special:MyLanguage/Help:Edit check#Paste check|Paste Check]] will become available at all Wikipedias this week. The feature prompts newcomers who are pasting text they are not likely to have written into VisualEditor to consider whether doing so risks a copyright violation. Paste Check [[mw:Special:MyLanguage/Edit check/Tags|tags]] all edits where it is shown for potential review. Local administrators can configure various aspects of the feature via [[{{#special:EditChecks}}]]. [[mw:Special:MyLanguage/Edit check/Paste Check#A/B Experiment|Research]] across 22 wikis found that Paste Check resulted in an 18% decrease in relative reverted-edits compared to the control group. Translators can [https://translatewiki.net/w/i.php?title=Special%3ATranslate&amp;group=ext-visualeditor-ve-mw-editcheck&amp;filter=&amp;optional=1&amp;action=translate help to localize] this and related features.
* The [[mw:Special:MyLanguage/Readers/Reader Experience|Reader Experience team]] will be standardizing the user menu in the top right for all mobile users so that it is closer to the desktop experience. Currently this user menu is only visible to users with Advanced Mobile Controls (AMC) turned on. The only change is that a couple buttons previously in the left-side menu will move to the top right for users who do not have AMC turned on. This change is expected to go out March 9 and seeks to improve the user interface. [https://phabricator.wikimedia.org/T413912]
* Starting in the week of March 2, the emails sent out when an email address was added, removed, or changed for an account will switch to a substantially nicer and clearer HTML email from the prior plaintext one. [https://phabricator.wikimedia.org/T410807]
* Notifications are currently limited to 2,000 historic entries per user, and extend back to 2013 when the feature was released. This is going to be changed to only store Notifications from the last 5 years, but up to 10,000 of them. This will help with long-term infrastructure health and help to prevent more recent notifications from disappearing too soon. [https://phabricator.wikimedia.org/T383948]
* The [[m:Special:GlobalWatchlist|Global Watchlist]] which lets you view your watchlists from multiple wikis on a single page continues to see improvements. The latest update improves label usage experience. The [[mw:Special:MyLanguage/Extension:GlobalWatchlist|extension]] now allows activating the [[mw:Special:MyLanguage/Manual:Language#Fallback languages|language fallback system]] for Wikidata items without labels in the viewed language, and showing those labels in the user’s preferred Wikidata language if no &lt;code dir=ltr&gt;uselang=&lt;/code&gt; URL parameter is provided. [https://phabricator.wikimedia.org/T373686][https://phabricator.wikimedia.org/T416111]
* The Wikipedia Android team has started a beta test of [[mw:Special:MyLanguage/Readers/Information Retrieval/Phase 1|hybrid search]] on Greek Wikipedia. Hybrid search capabilities can handle both semantic and keyword queries enabling readers to find what they’re looking for directly on Wikipedia more easily.
* For security reasons, members of certain user groups are [[m:Special:MyLanguage/Mandatory two-factor authentication for users with some extended rights|required to have two-factor authentication]] (2FA) enabled. Currently, 2FA is required to use the group, but not to be a member of it. Given that this model still has some vulnerabilities, the situation will [[phab:T418580|gradually change in March]]. Members of these groups will be unable to disable last 2FA method on their account, and it will be impossible to add users without 2FA to these groups. Users will still be able to add new authentication methods or remove them, as long as at least one method is continuously enabled. In the second half of March, users without 2FA will be removed from these groups. This applies to: CentralNotice administrators, checkusers, interface administrators, suppressors, Wikidata staff, Wikifunctions staff, WMF Office IT and WMF Trust &amp; Safety. Nothing will change for other users. See the linked task for deployment schedule. [https://phabricator.wikimedia.org/T418580]

'''Updates for technical contributors'''
* To help ensure [[mw:Special:MyLanguage/MediaWiki Product Insights/Responsible Reuse|fair use of infrastructure]], over the next month the Wikimedia Foundation will implement global API rate limits across our APIs. In early March, stricter limits will be applied to unidentified requests from outside Toolforge/WMCS and API requests that are made from web browsers. In April, higher limits will be applied to identified traffic. These limits are intentionally set as high as possible to minimise impact on the community. Bots running in Toolforge/WMCS or with the bot user right on any wiki should not be affected for now. However, all developers are advised to follow updated best practices. For more information, see [[mw:Special:MyLanguage/Wikimedia APIs/Rate limits|Wikimedia APIs/Rate limits]].
* The Wikidata Query Service Linked Data Fragment (LDF) endpoint will be decommissioned in February. This endpoint served limited traffic, which was successfully migrated to other data access methods that were better suited to support existing use cases. The hardware used to support the LDF endpoint will be reallocated to support the ongoing backend migration efforts. [https://phabricator.wikimedia.org/T415696]
* The new Parsoid parser [[mw:Special:MyLanguage/Parsoid/Parser Unification/Updates|continues to be deployed to additional wikis]], improving platform sustainability and making it easier to introduce new reading and editing features. Parsoid is now the default parser on 488 WMF wikis (268 Wikipedias), now covering more than 10% of all Wikipedia page views.
* The process and criteria for [[Special:MyLanguage/Wikimedia Enterprise#Access|requesting exceptional access]] to the high volume feed of the ''Wikimedia Enterprise'' APIs (at no cost for mission-aligned usecases), [[m:Talk:Wikimedia Enterprise#Exceptional access criteria|have now been published]]. This is to provide more thorough and clearer documentation for users.
* [https://techblog.wikimedia.org/ Tech Blog], the blog dedicated to the Wikimedia technical community [https://techblog.wikimedia.org/2026/02/24/a-tech-blog-diff/ will be migrating] to [[diffblog:|Diff]], the community news and event blog. The migration should be complete in April 2026, after which new posts will be accepted for publishing. Readers will be able to access posts – old and new – on the landing page at https://diff.wikimedia.org/techblog.

'''Weekly highlight'''
* [[m:Special:MyLanguage/Tech/Server switch|All wikis will be read-only]] for a few minutes on Wednesday, 25 March 2026 at [https://zonestamp.toolforge.org/1774450800 15:00 UTC]. This is for the datacenter server switchover backup tests, [[wikitech:Deployments/Yearly calendar|which happen twice a year]]. During the switchover, all Wikimedia website traffic is shifted from one primary data center to the backup data center to test availability and prevent service disruption even in emergencies.
* Last week, all wikis had 2 hours of read-only time, and extended unavailability for user-scripts and gadgets. This was due to a security incident which has since been resolved. Work is ongoing to prevent re-occurrences. For current information please see the [[m:Steward's noticeboard#Statement on Meta about today's user script security incident|post on the Stewards' noticeboard]] ([[m:Special:MyLanguage/Wikimedia Foundation/Product and Technology/Product Safety and Integrity/March 2026 User Script Incident|translations]]).

'''Updates for editors'''
* Users facing multiple blocks on mobile will now see the reasons for each block separately, instead of a generic message. This helps them understand why they are blocked and what steps they can take to resolve the issue. For example, users affected for using common VPNs (such as [[Special:MyLanguage/Apple iCloud Private Relay|iCloud Private Relay]]) will receive clearer guidance on what they need to do to start editing again. [https://phabricator.wikimedia.org/T357118]
* Later this week, [[mw:Special:MyLanguage/VisualEditor/Suggestion Mode|Suggestion Mode]] will become available as a beta feature within the visual editor at all Wikipedias. This feature proactively suggests various types of actions that people can consider taking to improve Wikipedia articles, and learn about related guidelines. The feature is locally configurable, and can also be locally expanded with custom Suggestions. Current settings can be seen at [[Special:EditChecks]] and there are [[mw:Special:MyLanguage/Help:Suggestion mode#For administrators %E2%80%93 local customization|instructions for how administrators can customize]] the links to point to local guidelines. The feature is connected to [[mw:Special:MyLanguage/Help:Edit check|Edit check]] which suggests improvements while someone is writing new content. In the future, the Editing team plans to evaluate the feature's impact with newcomers through a controlled experiment. [https://phabricator.wikimedia.org/T404600]
* [[File:Reload icon with two arrows.svg|12px|link=|class=skin-invert|Recurrent item]] View all {{formatnum:23}} community-submitted {{PLURAL:23|task|tasks}} that were [[m:Special:MyLanguage/Tech/News/Recently resolved community tasks|resolved last week]]. For example, the issue where the cursor became misaligned during the use of CodeMirror’s syntax highlighting, which makes wikitext and code easier to read, has now been fixed. This problem specifically affected users who defined a font rule in a custom stylesheet while creating a new topic with DiscussionTools. [https://phabricator.wikimedia.org/T418793]

'''Updates for technical contributors'''
* API rate limiting update: To help ensure [[mw:Special:MyLanguage/MediaWiki Product Insights/Responsible Reuse|fair use of infrastructure]], global API rate limits will be applied this week to requests without a compliant User-Agent that originate from outside Toolforge/WMCS and to unauthenticated requests made from web browsers. Higher limits will be applied to identified traffic in April. Bots running in Toolforge/WMCS or with the bot user right on any wiki should not be affected for now. However, all developers are advised to follow updated best practices. For more information, see [[mw:Special:MyLanguage/Wikimedia APIs/Rate limits|Wikimedia APIs/Rate limits]].
* The new GraphQL API has been released. The API was developed as a flexible alternative to select features of the Wikidata Query Service (WDQS), to improve developer experience and foster adaptability, and efficient data access. Try it out and [[d:Wikidata:Wikibase GraphQL#Feedback and development|give feedback]]. You can also [https://greatquestion.co/wikimediadeutschland/GraphQLAPI/apply sign up for usability tests].
* The [[m:Special:MyLanguage/Product and Technology Advisory Council/Unsupported Tools Working Group|PTAC Unsupported Tools Working Group]] continued improvements to [[commons:Special:MyLanguage/Commons:Video2commons#|Video2Commons]] in February, with fixes addressing authentication errors, large-file handling, task queue visibility, and clearer upload behavior. Work is still ongoing in some areas, including changes related to deprecated server-side uploads. Read [[m:Special:MyLanguage/Product and Technology Advisory Council/Unsupported Tools Working Group#February 2026|this update]] to learn more.

'''Updates for editors'''
* The [[mw:Special:MyLanguage/Help:Extension:CodeMirror|{{int:codemirror-beta-feature-title}}]] beta feature, also known as [[mw:Special:MyLanguage/Extension:CodeMirror|CodeMirror 6]], has been used for wikitext syntax highlighting since November 2024. It will be promoted out of beta by May 2026 in order to bring improvements and new [[mw:Special:MyLanguage/Help:Extension:CodeMirror#Features|features]] to all editors who use the standard syntax highlighter. If you have any questions or concerns about promoting the feature out of beta, [[mw:Special:MyLanguage/Help talk:Extension:CodeMirror|please share]]. [https://phabricator.wikimedia.org/T259059]
* Some changes to local user groups are performed by stewards on Meta-Wiki and logged there only. Now, interwiki rights changes will be logged both on Meta-Wiki and the wiki of the target user to make it easier to access a full record of user's rights changes on a local wiki. Past log entries for such changes will be backfilled in the coming weeks. [https://phabricator.wikimedia.org/T6055]
* On wikis using [[m:Special:MyLanguage/Flagged Revisions|Flagged Revisions]], the number of pending changes shown on [[{{#Special:PendingChanges}}]] previously counted pages which were no longer pending review, because they have been removed from the system without being reviewed, e.g. due to being deleted, moved to a different namespace, or due to wiki configuration changes. The count will be correct now. On some wikis the number shown will be much smaller than before. There should be no change to the list of pages itself. [https://phabricator.wikimedia.org/T413016]
* Wikifunctions composition language has been rewritten, resulting in a new version of the language. This change aims to increase service stability by reducing the orchestrator's memory consumption. This rewrite also enables substantial latency reduction, code simplification, and better abstractions, which will open the door to later feature additions. Read more about [[f:Special:MyLanguage/Wikifunctions:Status updates/2026-03-11|the changes]].
* Users can now sort search results alphabetically by page title. The update gives an additional option to finding pages more easily and quickly. Previously, results could be sorted by Edit date, Creation date, or Relevance. To use the new option, open 'Advanced Search' on the search results page and select 'Alphabetically' under 'Sorting Order'. [https://phabricator.wikimedia.org/T403775]
* [[File:Reload icon with two arrows.svg|12px|link=|class=skin-invert|Recurrent item]] View all {{formatnum:28}} community-submitted {{PLURAL:28|task|tasks}} that were [[m:Special:MyLanguage/Tech/News/Recently resolved community tasks|resolved last week]]. For example, the bug that prevented UploadWizard on Wikimedia Commons from importing files from Flickr has now been fixed. [https://phabricator.wikimedia.org/T419263]
'''Updates for technical contributors'''
* A new special page, [[{{#special:LintTemplateErrors}}]], has been created to list transcluded pages that are flagged as containing lint errors to help users discover them easily. The list is sorted by the number of transclusions with errors. For example: [[{{#special:LintTemplateErrors}}/night-mode-unaware-background-color]]. [https://phabricator.wikimedia.org/T170874]
* Users of the [[mw:Special:MyLanguage/Help:Extension:CodeMirror|{{int:codemirror-beta-feature-title}}]] beta feature have been using [[mw:Special:MyLanguage/Extension:CodeMirror|CodeMirror]] instead of [[mw:Special:MyLanguage/Extension:CodeEditor|CodeEditor]] for syntax highlighting when editing JavaScript, CSS, JSON, Vue and Lua content pages, for some time now. Along with promoting CodeMirror 6 out of beta, the plan is to replace CodeEditor as the standard editor for these content models by May 2026. [[mw:Special:MyLanguage/Help talk:Extension:CodeMirror|Feedback or concerns are welcome]]. [https://phabricator.wikimedia.org/T419332]
* The [[mw:Special:MyLanguage/Extension:CodeMirror|CodeMirror]] JavaScript modules will soon be upgraded to CodeMirror 6. Leading up to the upgrade, loading the &lt;code dir=ltr&gt;ext.CodeMirror&lt;/code&gt; or &lt;code dir=ltr&gt;ext.CodeMirror.lib&lt;/code&gt; modules from gadgets and user scripts was deprecated in July 2025. The use of the &lt;code dir=ltr&gt;ext.CodeMirror.switch&lt;/code&gt; hook was also deprecated in March 2025. Contributors can now make their scripts or gadgets compatible with CodeMirror 6. See the [[mw:Special:MyLanguage/Extension:CodeMirror#Gadgets and user scripts|migration guide]] for more information. [https://phabricator.wikimedia.org/T373720]
* The MediaWiki Interfaces team is expanding coverage of REST API module definitions to include [[mw:Special:MyLanguage/API:REST API/Extensions|extension APIs]]. REST API modules are groups of related endpoints that can be independently managed and versioned. Modules now exist for [https://phabricator.wikimedia.org/T414470 GrowthExperiments] and [https://phabricator.wikimedia.org/T419053 Wikifunctions] APIs. As we migrate extension APIs to this structure, documentation will move out of the main MediaWiki OpenAPI spec and REST Sandbox view, and will instead be accessible via module-specific options in the dropdown on the [https://test.wikipedia.org/wiki/Special:RestSandbox REST Sandbox] (i.e., [[{{#Special:RestSandbox}}]], available on all wiki projects).
* The [[mw:Special:MyLanguage/Extension:Scribunto|Scribunto]] extension provides different pieces of information about the wiki where the module is being used via the [[mw:Special:MyLanguage/Extension:Scribunto/Lua reference manual|mw.site]] library. Starting last week, the library also provides a [[mw:Special:MyLanguage/Extension:Scribunto/Lua reference manual#mw.site.wikiId|way]] of accessing the [[mw:Special:MyLanguage/Manual:Wiki ID|wiki ID]] that can be used to facilitate cross-wiki module maintenance.

Latest '''[[m:Special:MyLanguage/Tech/News|tech news]]''' from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. [[m:Special:MyLanguage/Tech/News/2026/13|Translations]] are available.

'''Weekly highlight'''
* Wikimedia site users can now log in without a password using passkeys. This is a secure method supported by fingerprint, facial recognition, or PIN. With this change, all users who opt for passwordless login will find it easier, faster, and more secure to log in to their accounts using any device. The new passkey login option currently appears as an autofill suggestion in the username field. An additional [[phab:T417120|&quot;Log in with passkey&quot; button]] will soon be available for users who have already registered a passkey. This update will improve security and user experience. The [[c:File:Passwordless_login_screencast.webm|screen recording]] demonstrates the passwordless login process step by step.
* [[m:Special:MyLanguage/Tech/Server switch|All wikis will be read-only]] for a few minutes on Wednesday, 25 March 2026 at [https://zonestamp.toolforge.org/1774450800 15:00 UTC]. This is for the datacenter server switchover backup tests, [[wikitech:Deployments/Yearly calendar|which happen twice a year]]. During the switchover, all Wikimedia website traffic is shifted from one primary data center to the backup data center to test availability and prevent service disruption even in emergencies.

'''Updates for editors'''
* Wikimedia site users can now export their notifications older than 5 years using a [[toolforge:echo-chamber|new Toolforge tool]]. This will ensure that users retain their important notifications and avoid them being lost based on the planned change to delete notifications older than 5 years, as previously announced. [https://phabricator.wikimedia.org/T383948]
* Wikipedia editors in Indonesian, Thai, Turkish, and Simple English now have access to Special:PersonalDashboard. This is an [[mw:Special:MyLanguage/Moderator Tools/Dashboard|early version of an experience]] that introduces newer editors to patrolling workflows, making it easier for them to move from making edits to participating in more advanced moderation work on their project. [https://phabricator.wikimedia.org/T402647]
* The [[Special:Block]] now has two minor interface changes. Administrators can now easily perform indefinite blocks through a dedicated radio button in the expiry section. Also, choosing an indefinite expiry provides a different set of common reasons to select from, which can be changed at: [[MediaWiki:Ipbreason-indef-dropdown]]. [https://phabricator.wikimedia.org/T401823]
* Mobile editors [[mw:Special:MyLanguage/Contributors/Account Creation Experiments#Logged-out|at several wikis]] can now see an improved logged-out edit warning, thanks to the recent updates from the Growth team. These changes released last week are part of ongoing efforts and tests to enhance [[mw:Special:MyLanguage/Contributors/Account Creation Experiments|account creation experience on mobile]] and then increase participation. [https://phabricator.wikimedia.org/T408484]
* [[File:Reload icon with two arrows.svg|12px|link=|class=skin-invert|Recurrent item]] View all {{formatnum:36}} community-submitted {{PLURAL:36|task|tasks}} that were [[m:Special:MyLanguage/Tech/News/Recently resolved community tasks|resolved last week]]. For example, the bug that prevented mobile web users from seeing the block information when affected by multiple blocks has been fixed. They can now see messages of all the blocks currently affecting them when they access Wikipedia.

'''Updates for technical contributors'''
* Images built using Toolforge will soon get the upgraded buildpacks version, bringing support for newer language versions and other upstream improvements and fixes. If you use Toolforge Build Service, review the recent [https://lists.wikimedia.org/hyperkitty/list/cloud-announce@lists.wikimedia.org/thread/EMYTA32EV2V5SQ2JIEOD2CL66YFIZEKV/ cloud-announce email] and update your build configuration as necessary to ensure your tools are compatible.

* The [https://api.wikimedia.org/wiki/Main_Page API Portal] documentation wiki will shut down in June 2026. API keys created on the API Portal will continue to work normally. api.wikimedia.org endpoints will be deprecated gradually starting in July 2026. Documentation on the API Portal is moving to [[mw:Wikimedia APIs|mediawiki.org]]. Learn more on the [[wikitech:API Portal/Deprecation|project page]].

'''Weekly highlight'''
* The Beta version of [[abstract:|Abstract Wikipedia]] a new Wikimedia project which is language-independent, was launched last week. The project allows communities to build Wikipedia articles in their native language, which can be readily accessed by other users in their own languages. The wiki is powered by instructions from Wikifunctions and also based on structured content from Wikidata. [[:f:Special:MyLanguage/Wikifunctions:Status updates/2026-03-26|Read more]].

'''Updates for editors'''
* The Growth team is running an A/B test to evaluate a clearer, more user-friendly message that promotes account creation on wikis. Currently when logged-out mobile users begin editing, they see a jarring warning message that can feel abrupt and discouraging. This also presents temporary account editing as the default rather than encouraging account creation. The test is running on ten Wikipedias, including Arabic, French, Spanish and German. [[mw:Special:MyLanguage/Contributors/Account Creation Experiments#2. Improve logged-out warning message (T415160)|Read more]].
* The Wikimedia Apps team is inviting feedback on [[mw:Special:MyLanguage/Wikimedia Apps/Team/Future of Editing on the Mobile Apps|how editing should work on the Wikipedia mobile apps]]. The discussion focuses on improving how users access editing tools when they tap &quot;Edit&quot;. This is part of a broader effort to convert readers who develop an interest in editing, to access a more user-friendly pathway to start contributing.

'''Updates for editors'''

* The [[mw:Special:MyLanguage/Help:Extension:CampaignEvents|CampaignEvents extension]] now includes a new group goal-setting feature, enabling organizers to set and track event goals such as the number of articles created and participating contributors in real time. Similarly, participants can work toward shared targets and see their collective impact as the event unfolds. The feature is now available on all Wikimedia wikis. Learn more in [[mw:Special:MyLanguage/Help:Extension:CampaignEvents/Registration/Collaborative contributions#Goal setting|the documentation]].
* [[File:Maki-gift-15.svg|12px|link=|class=skin-invert|Wishlist item]] The new [[mw:Special:MyLanguage/Help:Watchlist labels|watchlist labels]] feature (announced in [[m:Special:MyLanguage/Tech/News/2026/07|Tech News 2026-07]]) is now available via VisualEditor, the source editor, and the 'watchstar' (or watch link, for skins that don't have a star icon). Previously it was only possible to assign labels via [[Special:EditWatchlist|EditWatchlist]]. In all three places it is a new field following the expiry field.
* [[File:Reload icon with two arrows.svg|12px|link=|class=skin-invert|Recurrent item]] View all {{formatnum:23}} community-submitted {{PLURAL:23|task|tasks}} that were [[m:Special:MyLanguage/Tech/News/Recently resolved community tasks|resolved last week]]. For example, the issue where talk pages on mobile with Parsoid are unusable after empty section headers, has now been fixed. [https://phabricator.wikimedia.org/T419171]

'''Updates for technical contributors'''
* The [[m:Special:MyLanguage/WMDE Technical Wishes/Sub-referencing|sub-referencing feature]], which lets editors add details to an existing reference without duplicating it, will be gradually rolled out to [[phab:T414094|more wikis]] later this year. Wikis using the [[mw:Special:MyLanguage/Reference Tooltips|Reference Tooltips]] gadget are encouraged to update their version (typically at [[m:MediaWiki:Gadget-ReferenceTooltips.js|MediaWiki:Gadget-ReferenceTooltips.js]] as shown [https://en.wikipedia.org/w/index.php?diff=1344408362 here]) to ensure compatibility. Other reference-related gadgets may also be affected. [https://phabricator.wikimedia.org/T416304]
* All Wikinews editions will be closed and switched to read-only mode on 4 May 2026. Content will remain accessible, but no new edits or articles can be added. This closure was approved by the Board of Trustees of the Wikimedia Foundation following extended discussions. [[m:Wikimedia Foundation Board noticeboard#Board of Trustees Approves Closure of Wikinews|Read more]].
* The [[:mw:Special:MyLanguage/API:Action API|Action API]] has had several formats for requested output. One of them, &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;format=php&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt;, is being removed soon. Please ensure your scripts or bots use the [[mw:Special:MyLanguage/API:Data formats#Output|JSON format]]. This removal should affect very few scripts and bots. [https://phabricator.wikimedia.org/T118538]
* The [[Special:NamespaceInfo|Special:NamespaceInfo]] page now includes namespace aliases. For example &quot;WP&quot; for the &quot;Project&quot; (&quot;Wikipedia&quot;) namespace on the German Wikipedia. [https://phabricator.wikimedia.org/T381455]

Also, after reviewing [https://b24e11a4f1.catalyst.wmcloud.org/wiki/Category:Pages_using_article_guidance the outlines], please provide feedback on the [[mw:Talk:Article guidance|project talk page]]. Based on your input, the feature will be refined and transferred to the pilot Wikipedias to translate and adapt. Check out [[c:File:Article Guidance workflow demo - April 2026.webm|the video]] explaining the feature.
'''Updates for editors'''
* On most wikis, all autoconfirmed users can now use [[Special:ChangeContentModel|Special:ChangeContentModel]] page to [[mw:Special:MyLanguage/Help:ChangeContentModel|create new pages with custom content models]], such as mass message lists, making custom page formats more accessible. Check [[Special:ListGroupRights|Special:ListGroupRights]] for the status of your wiki. [https://phabricator.wikimedia.org/T248294]
* The Growth team has launched an [[mw:Special:MyLanguage/Contributors/Account_Creation_Experiments|account creation experiment]] to evaluate whether adding an account creation button to the mobile web header increases new account registrations and encourages more mobile users to contribute to the wikis. The experiment is currently live on Hindi, Indonesian, Bengali, Thai, and Hebrew Wikipedia, and targets 10% of logged-out mobile web users.

'''Updates for technical contributors'''
* Starting later this week, {{int:group-abusefilter}} who have the [[mw:Special:MyLanguage/Help:Extension:CodeMirror|{{int:codemirror-beta-feature-title}}]] beta feature enabled will have [[mw:Special:MyLanguage/Extension:CodeMirror|CodeMirror]] instead of [[mw:Special:MyLanguage/Extension:CodeEditor|CodeEditor]] as the editor at [[Special:AbuseFilter|Special:AbuseFilter]]. This is part of the broader effort to make the user experience more consistent across all editors. [https://phabricator.wikimedia.org/T399673][https://phabricator.wikimedia.org/T419332]

'''Updates for editors'''
* [[mw:Special:MyLanguage/Readers/Reader Experience/WE3.3.4 Reading lists|Reading lists]] is a feature which allows readers to save articles to a list for reading later. This feature is now in beta on Arabic, French, Indonesian, Vietnamese, and Chinese Wikipedias and by default for all new accounts on all Wikipedias.
* An experiment which explores extending [[mw:Special:MyLanguage/Readers/Reader Growth/Mobile page previews|Page Previews to mobile web]] will be launched in the week of April 20 on Arabic, English, French, Italian, Polish, and Vietnamese Wikipedias. Page Previews are pop-ups that display a thumbnail, lead paragraph, and a link to open the full article of a blue link, thereby improving content discovery. The feature is already available on desktop and in the apps. [[m:Special:MyLanguage/List of experiments in Product and Technology#Template|Read more about this experiment and others]].
* On several wikis, logged-in editors who haven't [[mw:Special:MyLanguage/Help:Email confirmation|confirmed their email addresses]] can now see a banner encouraging them to do so. Having the email address confirmed allows a user to restore access to the account if they lose it.

[https://phabricator.wikimedia.org/T28741]
* Following the recent implementation of global API rate limits on unidentified traffic, the Wikimedia Foundation will continue efforts to ensure [[mw:Special:MyLanguage/MediaWiki Product Insights/Responsible Reuse|fair use of infrastructure]] by applying global limits to identified API traffic beginning the last week of April. These limits are intentionally set as high as possible to minimise impact on the community. Bots running in Toolforge/WMCS or with the bot user right on any wiki should not be affected for now. However, all developers are advised to follow updated best practices. For more information, see [[mw:Special:MyLanguage/Wikimedia APIs/Rate limits|Wikimedia APIs/Rate limits]] and [[mw:Special:MyLanguage/Wikimedia APIs/Rate limits/FAQ|Frequently Asked Questions]].
* The [[mw:Special:MyLanguage/Attribution API|Attribution API]] is now available as a [[mw:Special:MyLanguage/Wikimedia APIs/Stability policy|beta]]. The API fetches information for crediting Wikimedia articles and media files wherever they are used. Reference documentation is available through the REST Sandbox special page available on all Wikimedia wikis (such as the [https://en.wikipedia.org/w/index.php?api=attribution.v0-beta&amp;title=Special%3ARestSandbox REST sandbox on English Wikipedia]). Share your feedback on the [[mw:Talk:Attribution API|project talk page]].
* There is no new MediaWiki version this week.

'''Updates for editors'''
* There is a change in how new users are autoconfirmed that will improve anti-vandalism protection. Currently, users who have had an account for a few days and made a few edits are automatically added to the [[{{int:grouppage-autoconfirmed/{{CONTENTLANGUAGE}}}}|{{int:group-autoconfirmed}}]] group. This configuration tends to be exploited by some vandals, who create accounts and start to use them only after some time. To mitigate this, the configuration will be updated next week so that – for the purpose of becoming autoconfirmed – the account age will be counted from their first edit, instead of registration date. The numeric value of the age threshold will remain the same. This change will be deployed only to wikis which require at least one edit as part of the autoconfirmation conditions. [https://phabricator.wikimedia.org/T418484]
* All Wikipedia users with new accounts and those who activated the &quot;automatically enable most beta features&quot; option in their preference can now use the [[mw:Special:MyLanguage/Readers/Reader Experience/WE3.3.4 Reading lists|reading lists]] beta feature to save articles for later reading. This helps organize reading interests in one place for convenient access.

* As a reminder, the global API rate limits will be applied this week to identified API traffic. This is to help ensure [[mw:MediaWiki Product Insights/Responsible Reuse|fair use of infrastructure]]. Bots running in Toolforge/WMCS or with the bot user right on any wiki should not be affected for now. However, all developers are advised to follow updated best practices.

'''Weekly highlight'''
* The [[mw:Special:MyLanguage/Article guidance|Article guidance]] team invites experienced editors of [[mw:Special:MyLanguage/Article guidance/Pilot wikis and collaborators|pilot Wikipedias]]—Arabic, Bangla, Japanese, Portuguese, Persian, Turkish, Simple English, Spanish, and French—to help translate and adapt [https://b24e11a4f1.catalyst.wmcloud.org/wiki/Category:Pages_using_article_guidance sample outlines]. These outlines will guide editors in creating clear, well-structured, and policy-compliant articles when using [https://b24e11a4f1.catalyst.wmcloud.org/wiki/Special:NewArticle the feature] once it is launched in May 2026. [[mw:Special:MyLanguage/Article guidance#Adapting a sample outline in a Wikipedia|Simple instructions]] on how to translate and adapt the outlines are available.
'''Updates for editors'''
* The [[:m:Special:MyLanguage/Product and Technology Advisory Council|Product and Technology Advisory Council]] has published [[:m:Special:MyLanguage/Product and Technology Advisory Council/May 2026 draft PTAC recommendation for feedback|draft recommendations]] on a model that affiliates can follow when contributing to the technical space. Community members are invited to provide feedback on the recommendation until May 8th [[:m:Talk:Product and Technology Advisory Council/May 2026 draft PTAC recommendation for feedback|on the talk page]].
* The number of available thumbnail size preferences in MediaWiki is being reduced to three standardized options—Small (180px), Regular (250px), and Large (400px), as part of ongoing efforts to improve performance and reduce strain on thumbnail services. As a result, existing preferences will be mapped to the nearest new size (for example, smaller selections like 120px or 150px will render at 180px, while larger ones like 300px or 360px will render at 400px). The preferences interface will soon be updated to reflect these changes, and users who wish to opt out or provide feedback can do so. [https://phabricator.wikimedia.org/T424909]
* From now on, even when a permission expires automatically, users will receive an Echo notification similar to the standard notification for permission changes. There is a difference between this and [[m:Special:MyLanguage/Global reminder bot|Global reminder bot]] in that the latter reminds users a week ''before'' the rights are due to expire, so that they can renew the rights.

For example, the problem where the ULS language selector in [[m:Special:Translate|Special:Translate]] would scroll vertically when it shouldn't, has been resolved. Previously, when users opened the &quot;Translate to English&quot; dropdown and typed certain inputs, the dialog would scroll vertically by a few pixels even when there was enough space to display all results. The dropdown no longer shifts unnecessarily when filtering languages. [https://phabricator.wikimedia.org/T358864] 
* The [[m:Special:GlobalWatchlist|Global Watchlist]], which lets you view your watchlists from multiple wikis on a single page, continues to improve. For example, watchlists for Wikibase sites such as [[:d:|Wikidata]] now support [[mw:Special:MyLanguage/Extension:EntitySchema|EntitySchema]] elements for better tracking. The Live Updates mode now refreshes the special page every 60 seconds to comply with the updated [[mw:Special:MyLanguage/Wikimedia APIs/Rate limits|global API rate limits]] for improved real-time responsiveness. Additionally, a directionality bug that displayed links as &quot;changes 3&quot; instead of &quot;3 changes&quot; in mixed-direction lists has been fixed.

* The second phase of [[mw:Special:MyLanguage/Wikimedia APIs/Rate limits|global API rate limits]] has been rolled out to reduce the [[diffblog:2026/03/26/quo-vadis-crawlers-progress-and-whats-next-on-safeguarding-our-infrastructure/|impact of AI crawlers]] and ensure fair, sustainable access to Wikimedia resources, prioritising human and mission-aligned traffic. [[mw:Special:MyLanguage/Wikimedia APIs/Rate limits#Limits|Limits]] have been shifted from per-hour to per-minute, producing smoother traffic patterns and more predictable API load. Community users are not expected to be affected, and no action is required. Early indications show some User-Agent-based requestors are adjusting behaviour, and around 64% of automated API traffic has been identified. Monitoring continues, and Wikimedia Enterprise remains available for commercial support.

* The Reader Growth team is launching an experiment to test a new [[mw:Special:MyLanguage/Readers/Reader_Growth/Share_Card|Share Card feature]] that allows readers to create visually engaging cards from Wikipedia articles or selected article sections and share them online, with each card linking back to the original article to help expand readership and article discovery. The mobile-only A/B test will be available to a portion of readers on Arabic, Chinese, French, Vietnamese, and English Wikipedia to better understand reading and sharing habits, and is scheduled to begin the week of May 18 and run for four weeks.
* The Android and iOS Wikipedia apps recently released the [[mw:Special:MyLanguage/Wikimedia_Apps/Team/25th_Birthday_Reading_Challenge|25-day reading challenge]] into Beta, as part of efforts to drive reader engagement by encouraging users to complete reading milestones.

* The Abstract Wikipedia team has identified five potential pilot wikis to assess their interest in adopting abstract articles on their wikis. The pilots are Malayalam, Bengali, Dagbani, Arabic, and Indonesian Wikipedia. The feedback period will be open until May 22. If your community is interested in becoming a pilot, [[m:Talk:Abstract Wikipedia|let us know on Meta]].

'''Updates for editors'''
* An experiment to show [[mw:Special:MyLanguage/Readers/Reader Experience/Reading lists|Reading Lists]] to logged-out readers on mobile web will launch on May 18 across German, Spanish, Italian, Portuguese, Polish, Dutch, Turkish, and Urdu Wikipedias, and will run for one month. The effort supports broader goals of helping readers save and organize articles for later reading, while encouraging habits that could lead to future Wikipedia contributions.
* To support a bookmark button in the Reading List beta feature, the &quot;Tools &gt; Action&quot; menu has been updated to display icons, including the watch star indicator that helps editors identify temporarily watched articles. The icons now also match those used on mobile, improving consistency across platforms. The change is currently limited to the actions menu and mainly affects editors with privileged user rights. [https://phabricator.wikimedia.org/T426008]
* [[mw:Special:MyLanguage/VisualEditor/Suggestion Mode|Suggestion Mode]] was released as an [[w:en:A/B test|A/B test]] for newcomer editors on the mobile website at [[phab:T421189|~15 Wikipedias]]. The experiment will measure the impact that Suggestion Mode has on the proportion of newcomer mobile web edit sessions that result in constructive (un-reverted) article edits. The experiment will also evaluate the feature's impact on editor retention, and monitor changes in revert and block rates.

* On English, French, Japanese, and a few other Wikipedias, there was a [[diffblog:2025/09/02/better-detecting-bots-and-replacing-our-captcha/|trial of hCaptcha]], a third-party bot detection service. The trial showed that hCaptcha effectively detects and deters some bad-faith automated activity, on its own and by giving [[w:en:Wikipedia:Village pump (technical)/Archive 225#Introducing SuggestedInvestigations|checkusers and stewards]] signals to look into. Because the results were positive, hCaptcha will be rolled out across all wikis over the next few weeks. [[mw:Special:MyLanguage/Product Safety and Integrity/Anti-abuse signals/hCaptcha|See the hCaptcha project page]] for technical information about the implementation and privacy protections.

* The latest Community Tech update is now available, with progress across several Community Wishlist initiatives, including Reading Lists expansion from the mobile app to the website, new language support for &quot;Who Wrote That&quot; and the Personal Dashboard, improvements to 3D rendering and Charts, and upcoming work on talk page sorting, audio playback, and editing workflows. The update also shares current priorities, wishlist status trends, and opportunities for community feedback on future focus areas and the Wikimedia Foundation’s 2026–2027 Annual Plan.

* Following a [[mw:Special:MyLanguage/Contributors/Account Creation Experiments#LOWM|successful account creation experiment]], an improved logged-out edit warning message will be deployed to all Wikimedia wikis in the first week of June. The change will only affect logged-out users on mobile web who open an editing session. The updated experience is designed to encourage account creation more clearly, while still allowing users to edit with temporary accounts. Results from the experiment showed a significant increase in account creation, with a 27% relative lift among users shown the updated message. As expected, as more people funnel into account creation, temporary accounts decreased by a relative 16%. The experiment did not show any significant changes in constructive edit rates or other monitored contributor metrics. [https://phabricator.wikimedia.org/T424595] 

'''Updates for editors'''
* For security reasons, members of certain user groups are [[m:Special:MyLanguage/Mandatory two-factor authentication for users with some extended rights|required to have two-factor authentication]] (2FA) enabled. Members of these groups will be unable to disable the last 2FA method on their account, and it will be impossible to add users without 2FA to these groups. Users will still be able to add new authentication methods or remove them, as long as at least one method is continuously enabled. In the next few weeks, users without 2FA will be removed from these groups. Notably, this applies to bureaucrats. See the linked tasks for deployment schedules. [https://phabricator.wikimedia.org/T423119][https://phabricator.wikimedia.org/T423120]
* [[m:Special:MyLanguage/WMDE Technical Wishes|WMDE Technical Wishes]] will run an [[w:en:A/B testing|A/B test]] on [[:phab:T415904|10 wikis]], testing [[m:WMDE Technical Wishes/References/Reference Previews|potential improvements for Reference Previews]]. The experiment will run for ~2 weeks at the end of May / beginning of June and will affect 10% of desktop readers on the participating wikis.
* After two successful experiments, the Reader Growth team is rolling out an [[mw:Special:MyLanguage/Readers/Reader Growth/Image Browsing|Image Browsing]] beta feature for all Wikipedias on mobile on May 25. This means that anyone who has all beta features on by default will start to see this feature, and others can check the box to turn it on in their preferences. The beta feature will include a carousel of all an article's images at the top of the article, with controls for editors to [[mw:Readers/Reader_Growth/Image_Browsing#Phase_2.1_beta_feature|exclude images from the article's carousel or to exclude an article from the feature entirely]].

Latest '''[[m:Special:MyLanguage/Tech/News|tech news]]''' from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. [[m:Special:MyLanguage/Tech/News/2026/24|Translations]] are available.

'''Weekly highlight'''
* Wikimedia Enterprise has increased the free usage limits for its API offerings. The monthly request limit for the On-demand API has increased from 5,000 to 50,000 requests, while the Snapshot API limit has increased from 15 to 30 requests per month. In addition, Structured Contents snapshots are now available for free accounts. These changes expand access to Wikimedia Enterprise data for developers, researchers, and organizations using Wikimedia content. [https://enterprise.wikimedia.com/blog/enhanced-free-api]

'''Updates for editors'''
* The [[mw:Special:MyLanguage/Wikimedia_Apps/Team/Explore Feed Refresh/Phase 1|refreshed Explore Feed]], now called the Home Feed, is rolling out to 50% of users of the Wikipedia Android app. The Home Feed helps readers discover relevant content through two new tabs: ''Community'' and ''For You''. The Community tab provides a scrollable feed of curated content and updates from the broader Wikimedia community and movement, while the ''For You'' tab offers a full-screen, swipeable experience that shows content tailored to a user's interests. The redesign is part of a broader effort to improve discovery and enhance the learning experience in the Wikipedia app.
* The [[mw:Special:MyLanguage/Wikimedia Apps/Team/iOS/&quot;Which came first?&quot; Game|Which came first?]] daily trivia game is now available in the beta version of the Wikipedia iOS app in English, German, French, Portuguese, Russian, Spanish, Arabic, Chinese, and Turkish. The game uses historical events from Wikipedia's &quot;On This Day&quot; content and challenges readers to guess which of two events happened first. The game was previously released on Android. Communities interested in making the game available in their languages can [[mw:Special:MyLanguage/Wikimedia_Apps/Team/Games#Game availability by language|read the instructions and requirements]].
* [[m:Special:MyLanguage/WMDE Technical Wishes/Sub-referencing|Sub-referencing]], a new MediaWiki feature that allows editors to reuse references with different details, will begin rolling out to Wikimedia wikis following a successful pilot phase. Deployment will start on 8 June for most [[wikitech:Deployments/Train#Wednesday|Group 1 wikis]] and French Wikipedia, with additional Wikipedia language editions receiving the feature over the coming months. Communities are encouraged to prepare by checking for [https://translatewiki.net/w/i.php?title=Special%3ATranslate&amp;group=ext-cite&amp;language=en&amp;action_source=search&amp;filter=%21translated&amp;optional=1&amp;action=translate untranslated Cite extension messages] in their language and reviewing any use of [[mw:Special:MyLanguage/Reference Tooltips|Reference Tooltips]], which may require [[:phab:T416304#11668731|updates]] to support the new functionality. Wikis using [[mw:Special:MyLanguage/Help:Reference Previews|Reference Previews]] do not need to take any action. Communities may also wish to create the ''cite-tracking-category-ref-details'' [[Special:TrackingCategories|tracking category]] as a hidden category using &lt;code&gt;&lt;nowiki&gt;__HIDDENCAT__&lt;/nowiki&gt;&lt;/code&gt; (or a dedicated template), and connect it to the corresponding Wikidata item [[d:Q129764848]]. [https://phabricator.wikimedia.org/T425662]
* The [[mw:Special:MyLanguage/Readers/Reader Growth/Mobile page previews#Experimentation|Page Previews experiment]] on mobile web has concluded. The team decided not to roll out the feature after the results showed no statistically significant impact on reader retention, as the primary success metric was retention improvement. Page Previews, which are already available on desktop and in the apps, display a thumbnail, lead paragraph, and link to the full article when readers tap a blue link. The experiment tested this experience on mobile web across six Wikipedias.
* The [[mw:Special:MyLanguage/Codex/Design/Icons|user interface icon library]] will be [[phab:T399175|updated later this week or next week]]. Most of the ~300 icons have been slightly refined and ~30 new icons have been added. These changes improve the icons to make them more consistent and comprehensible, and provide more visual balance when they are used in groups.
* The [[mw:Special:MyLanguage/Universal Language Selector|Universal Language Selector]] (ULS) interface in MediaWiki, which helps users select content in other languages, has been updated. The new version improves speed and accessibility, and users of Wikimedia projects can now pin languages for quicker language switching. The deployment to Wikimedia sites will happen gradually in the coming weeks. You can test it now as a beta feature by selecting [[Special:Preferences#mw-prefsection-betafeatures|beta features]] in your profile preferences and share your feedback on [[mw:Special:MyLanguage/Universal Language Selector/New ULS|the project page]].

'''Updates for technical contributors'''
* The function signature for &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;mw.util.addPortletLink()&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; has been simplified. Developers can now pass a configuration object instead of a list of positional parameters when creating portlet links. The previous function signature remains supported for backwards compatibility. For example, instead of: &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;mw.util.addPortletLink('p-cactions', '#', 'Stub', 'ca-stubtag', 'Add a stub tag to this page');&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; use &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;mw.util.addPortletLink('p-cactions', { href: '#', text: 'Stub', id: 'ca-stubtag', tooltip: 'Add a stub tag to this page' });&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt;. Script maintainers are encouraged to review existing uses of &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;addPortletLink()&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; and update them where appropriate. This change will be available on all wikis from 11 June. Thanks to community volunteer Gerges for contributing this improvement. [https://phabricator.wikimedia.org/T427945]
* '''Community Wishlist discussion''': Product &amp; Technology [[m:Special:MyLanguage/Community Wishlist/Updates#May 20, 2026: Community Tech becomes a program|introduced changes]] meant to increase the number and complexity of wishes fulfilled, including the disbanding of the Community Tech team. They are [[m:Special:MyLanguage/Community Wishlist/Updates|engaging in discussions]] about a [[m:Talk:Community Wishlist#Proposed direction for Wishlist|proposed direction for the wishlist]] from community members.

'''Weekly highlight'''
* The [[mw:Special:MyLanguage/Readers/Reader Growth|Reader Growth team]] has launched an [[mw:Special:MyLanguage/Readers/Reader Growth/Image Browsing|Image Browsing]] beta feature on the mobile web version of all Wikipedias. The feature shows an image carousel at the top of articles with 3 or more images. Editors can configure this feature with the following controls: to hide a specific image from a page, either use &lt;code&gt;class=notpageimage&lt;/code&gt; excluding it from thumbnail previews, or &lt;code&gt;class=noviewer&lt;/code&gt; excluding it from MediaViewer. The carousel can also be disabled from a page entirely, with the magic word &lt;code&gt;&lt;nowiki&gt;__NOMEDIAVIEWERCAROUSEL__&lt;/nowiki&gt;&lt;/code&gt;. To submit feedback or flag bugs, please visit the [[mw:Talk:Readers/Reader Growth/Image Browsing|project page]]. 
* [[mw:Special:MyLanguage/Help:Tables#class=&quot;wikitable&quot;|Wikitables]] can now be [[mw:Special:MyLanguage/Help:Sortable tables#Forcing the initial sort direction|sorted in descending order]] on the first click by adding &lt;code dir=ltr&gt;data-sort-order=&quot;desc&quot;&lt;/code&gt; to the header cell. Previously, by default, clicking a column header for the first time sorts it in ascending order. This addition to a Wikitable gives it more control and flexibility, while the default behavior for subsequent clicks remains unchanged. [https://phabricator.wikimedia.org/T398416]

'''Updates for editors'''
* The [[mw:Special:MyLanguage/Article guidance|Article guidance]] feature is currently being tested with some editors creating new articles on the Simple English, French, and Turkish Wikipedias. The experiment will soon begin on the Arabic and Bangla Wikipedias as well. [[w:simple:Special:NewArticle|This feature]] gives editors community-curated guidance to help them create articles that follow community standards. Experienced editors can continue creating or adapting outlines for specific article types that are commonly created by less experienced contributors. The outlines guide less experienced editors in creating high-quality articles. A quick guide to markups used in outlines can be found on [[mw:Special:MyLanguage/Article guidance/Test feature guide#Markups in outlines|this page]]. [[w:simple:Wikipedia:Article Guidance|Example outlines]] that can be adapted and instructions for how to adapt them are on [[mw:Special:MyLanguage/Article guidance#Adapting a sample outline in a Wikipedia|this section]] of the project page.
* Wikis that wish to replace the &quot;indefinitely&quot; button in Special:Block for temporary accounts (for example, wikis that block temporary users only until account expiration) will be able to do so by creating [[MediaWiki:ipb-indefinite-expiry-temporary-account]] with the block duration they want. [https://phabricator.wikimedia.org/T427125]

'''Updates for technical contributors'''
* By the end of June, a valid user-agent string will be required for automated dumps downloads from the dumps.wikimedia.org website. Automated requests that provide a generic or empty user-agent will be blocked. This [[phab:T400119|extends enforcement]] of the long standing [[foundation:Special:MyLanguage/Policy:Wikimedia Foundation User-Agent Policy|user-agent policy]]. Access to dumps through Wikimedia Cloud Services will not change.
* The roll out of global [[mw:Wikimedia APIs/Rate limits|API rate limits]] is now complete, with limits enforced across all APIs and at the documented levels for all groups. Bots running in Toolforge/WMCS or with the bot user right on any wiki remain exempt. All bots should continue to follow the documented best practices to avoid being rate limited.
* The [https://api.wikimedia.org/wiki/Main_Page API Portal wiki] will be read only starting this week (June 15-18). The following week (June 22-25), all API Portal wiki URLs will redirect to [[mw:Wikimedia APIs|Wikimedia APIs on mediawiki.org]]. Learn more on the [[wikitech:API Portal/Deprecation|project page]].

* Starting next week, abuse filters that are set to &quot;require CAPTCHA verification&quot; will begin to also affect users with the &lt;code&gt;skipcaptcha&lt;/code&gt; right, which includes most autoconfirmed users. Bots are exempted. This change only affects edits that trigger an abuse filter.

'''Updates for editors'''
* As part of the [[mw:Special:MyLanguage/Contributors/Account Creation Experiments|Account Creation Experiments]], the Growth team tested adding a user account icon in the mobile web header for logged-out users, providing direct access to &quot;Create account&quot; and &quot;Log in&quot; actions. The experiment increased account creation by about 20% without negatively affecting edit quality or constructive edit rates. The feature will now be rolled out to all Wikimedia Foundation wikis on mobile web in the first week of July. [https://phabricator.wikimedia.org/T428220]
* After a [[phab:T426248|successful experiment]], logged-in users who did not [[mw:Special:MyLanguage/Help:Email_confirmation|confirm their email address]] when their account was created see a new banner asking them to complete that process. This helps reduce the risk that users get locked out of their account, and makes account email addresses overall more reliable. This is part of the [[mw:Special:MyLanguage/Product Safety and Integrity/Account Security|Account Security]] project. [https://phabricator.wikimedia.org/T428292]
* An update to [[Special:Search|Search]] is refining how the &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;-prefix:&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; behaves when used to exclude results. Previously, using &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;-prefix:&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; with negation could unintentionally broaden search results by adding the namespaces included in the search scope, leading to confusing behavior for users expecting a straightforward exclusion filter. With the update, &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;-prefix:&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; will now strictly exclude matching page titles as intended and may display a warning if the relevant namespace has not been explicitly selected. The behavior of &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;prefix:&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; without negation however remains unchanged.

'''Updates for technical contributors'''
* In preparation for [[m:Special:MyLanguage/Event:Celebrate Women|Celebrate Women campaign]] planned for March 2027, the Wikimedia Foundation’s [[m:Special:MyLanguage/Wikimedia Foundation/Advancement/Community Growth/Content Enablement|Content Enablement team]] has launched a 22-question survey to better understand technical contributions by women+ (anyone who identifies as a woman) across Wikimedia projects. The survey takes approximately 15–20 minutes to complete and will remain open until 20 July 2026. The [[m:Special:MyLanguage/Celebrate Women/Technical contributions survey|questions]] are also available on-wiki for review in advance.
* The [[mw:Special:MyLanguage/Extension:Score|Score extension]] now supports rendering music scores as SVG images in addition to PNG, addressing a long-standing [[:phab:T49578|feature request]] and resolving historical image quality issues. Both formats are now provided to clients, with PNG in the &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;src&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; attribute and SVG in the &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;srcset&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; attribute.
* The new [[wikitech:Parsoid|Parsoid]] parser [[mw:Special:MyLanguage/Parsoid/Parser_Unification/Updates|continues to be deployed to additional wikis]], making it easier to introduce new reading and editing features. It was enabled on French Wikipedia, bringing total progress to covering 78.9% of Wikipedia page views. Rollout to English Wikipedia desktop will progress through this week.

Latest '''[[m:Special:MyLanguage/Tech/News|tech news]]''' from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. [[m:Special:MyLanguage/Tech/News/2026/29|Translations]] are available.

'''Updates for editors'''
* [[mw:Special:MyLanguage/Growth/Revise_Tone|Revise Tone]] helps newcomers identify passages in Wikipedia articles that may contain non-encyclopedic language and encourages them to consider revising the tone. The feature was [[w:en:A/B_testing|A/B tested]] on the Arabic, English, French, and Portuguese Wikipedias, where newcomer task completion rates [[mw:Special:MyLanguage/Growth/Revise_Tone#Experiment_Results|increased by 38.7%]] compared to the default Copyedit task, with no decrease in edit quality. The test ended on July 9, and the feature is now available for everyone on these wikis, configurable via Community Configuration. [[phab:T426364|The plan]] is to release Revise Tone to more wikis.
* The community configuration that allows [[mw:Special:MyLanguage/Help:Growth/Mentorship#Automated mentor list cleanup|automatic removal of inactive mentors]] based on configurable criteria will be enabled on Thursday 16, [[mw:Special:MyLanguage/Growth/Deployment|on some wikis]] to keep mentor lists up to date. Mentors are experienced contributors who opt in to help new users on-wiki through the [[mw:Special:MyLanguage/Growth/Feature summary|Growth Features]]. Administrators can now prepare the settings via [[w:Special:CommunityConfiguration/Mentorship|Special:CommunityConfiguration/Mentorship]]; they will take effect starting Thursday.
* [[File:Reload icon with two arrows.svg|12px|link=|class=skin-invert|Recurrent item]] View all {{formatnum:38}} community-submitted {{PLURAL:38|task|tasks}} that were [[m:Special:MyLanguage/Tech/News/Recently resolved community tasks|resolved last week]]. For example, an issue where some users of the Wikipedia Android app were logged out immediately after signing in, preventing them from staying logged in and editing pages, has now been fixed. [https://phabricator.wikimedia.org/T316916]

'''Updates for technical contributors'''
* Editing a page via user scripts or gadgets was causing watchlist labels that the user had assigned to that page to reset. This has now been fixed. [https://phabricator.wikimedia.org/T423778]
* To work around a Safari bug (see [[phab:T425211]]), on Parsoid-enabled wikis, wikilink hrefs now use absolute urls instead of protocol-relative urls. REST API output remains unchanged and continue to use protocol-relative urls. Gadgets, user scripts, bots, and CSS might need to be adapted if they relied on the presence of protocol-relative urls in wikilink hrefs. [https://phabricator.wikimedia.org/T431358]
* [[File:Reload icon with two arrows.svg|12px|link=|class=skin-invert|Recurrent item]] Detailed code updates later this week: [[mw:MediaWiki 1.47/wmf.11|MediaWiki]]

'''In depth'''
* The Wikimedia Foundation’s Experiment Platform Team has published a blog post reflecting on its first year of structured experimentation. It highlights successful experiments such as Paste Check, Reference Check, and Tone Check, which improved editing outcomes and have been rolled out to more users, as well as experiments that did not lead to product changes.

Latest '''[[m:Special:MyLanguage/Tech/News|tech news]]''' from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. [[m:Special:MyLanguage/Tech/News/2026/30|Translations]] are available.

'''Updates for editors'''
* The [[mw:Special:MyLanguage/Reader/Reader Experience|Reader Experience team]] has incorporated community feedback around the placement of watchstar and watchlist buttons for the [[mw:Special:MyLanguage/Readers/Reader Experience/WE3.3.4 Reading lists|Reading Lists beta feature]], which would allow for saving articles for later reading – a [[m:Special:MyLanguage/Community Wishlist/W102|wishlist item]] to bring the functionality to web. Editors are invited to enable the beta feature to test it out and [[phab:T426453|share their thoughts]].
* [[mw:Special:MyLanguage/VisualEditor/Suggestion Mode|Suggestion Mode]] offers edit suggestions within the VisualEditor for improving Wikipedia articles. [[Special:EditChecks|All suggestions]] are [[mw:Special:MyLanguage/Help:Suggestion mode#For administrators – local customization|community-configurable]]. The [[mw:Special:MyLanguage/Edit check/TextMatch|TextMatch]] feature is a way for volunteers to create custom local suggestions. The feature searches in articles for strings of text, and now includes support for regular expressions. This gives volunteers greater precision and flexibility over the kinds of local suggestions they can create. Note: Suggestions [[mw:Special:MyLanguage/Edit check/Configuration#:~:text=maximumEditcount|can be targeted]] based on the edit count of the person editing as well as other aspects of the page. You can [[mw:Special:MyLanguage/Help:Suggestion mode#Create custom local types of Suggestions|find examples from other communities]] for inspiration, including TextMatches that detect: typos, grammar-errors, potential advertisements, clichés, incorrect dash or hyphen usage, non-specific time keywords, outdated names, and more. Any [[mw:Special:MyLanguage/Talk:VisualEditor/Suggestion Mode|feedback]] is appreciated.
* [[File:Reload icon with two arrows.svg|12px|link=|class=skin-invert|Recurrent item]] View all {{formatnum:27}} community-submitted {{PLURAL:27|task|tasks}} that were [[m:Special:MyLanguage/Tech/News/Recently resolved community tasks|resolved last week]]. For example, an issue where the SVG Translate tool could use an outdated version of a file, causing existing translations to be overwritten when new ones were uploaded, has now [[phab:T430577|been fixed]]. Overall, in the last quarter from April – June 2026 about 337 community tasks were resolved by the Wikimedia Foundation.

'''Updates for technical contributors'''
* On Parsoid-enabled wikis, Parsoid now renders a maximum of 1,250 images per page. A new tracking category, &quot;media-limit-reached&quot;, will be soon made available to identify pages where this limit is reached, making it easier to find content whose media output may have been restricted during rendering. See [[phab:T430854]] for more information and to provide feedback.

'''Updates for editors'''
* [[File:Maki-gift-15.svg|12px|link=|class=skin-invert|Wishlist item]] [[mw:Special:MyLanguage/ContentTranslation|Content Translation]] now supports dark mode, fulfilling a [[m:Community Wishlist/W544|Community Wishlist request]]. This brings the tool in line with the accessibility features available in the Vector 2022 and Minerva skins, helping reduce visual fatigue for users translating content. [https://phabricator.wikimedia.org/T367077]
* DiscussionTools' source mode and the 2017 wikitext editor will now offer autocomplete for links (&lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;[[&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt;), templates (&lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;{{&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt;), HTML and parser tags (&lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;&lt;&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt;), and magic words (&lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;__&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt;), making it quicker and easier to insert links, templates, and other wiki markup while editing. [https://phabricator.wikimedia.org/T432400]
* The [[mw:Special:MyLanguage/Readers/Reader Growth/Mobile page previews|Readers Growth team]] has concluded its experiment with mobile page previews and will not roll out the feature. Page Previews are a pop-up bottom sheet that appears when readers tap a blue link, showing a thumbnail, lead paragraph, and an option to open the article. The experiment showed flat retention and negative indicator metrics, suggesting that mobile web readers preferred navigating directly to linked articles rather than using page previews.
* The Reader Experience team has seen encouraging early results from the [[mw:Special:MyLanguage/Readers/Reader Experience/Reading lists|Reading Lists feature]], with 93% of participating users reporting that it was useful. Reading Lists help active readers save articles for future reading and support their learning goals on Wikimedia projects. The team plans further improvements before expanding the feature to more users.
* The [[mw:Special:MyLanguage/Wikimedia Apps/Team/Explore Feed Refresh|Explore Feed Refresh]] initiative was tested with new and casual Wikipedia app readers. The refreshed feed helps readers discover new and relevant content. After a 10.5% increase in engagement with the feed, Wikimedia Apps team has decided to scale the Home Feed redesign to iOS with the learnings from the Android release applied.
* [[File:Reload icon with two arrows.svg|12px|link=|class=skin-invert|Recurrent item]] View all {{formatnum:23}} community-submitted {{PLURAL:23|task|tasks}} that were [[m:Special:MyLanguage/Tech/News/Recently resolved community tasks|resolved last week]]. For example, an issue where subject names in the Article Guidance feature were displayed with incorrect capitalization on French Wikipedia, has now been fixed. Subject names will now follow the correct capitalization rules for the language. [https://phabricator.wikimedia.org/T427201]

'''Updates for technical contributors'''
* After running several [[mw:Special:MyLanguage/Contributors/Account Creation Experiments|Account Creation Experiments]] to improve registration completion rates, a new version of the username field on [[Special:CreateAccount|Create Account]] has been rolled out. It includes [[:c:File:Create account - July 2026 updates.png|a popover summarizing the username policy]] to provide clearer guidance during account creation. As part of this change, the messages &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;createacct-helpusername&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; and &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;createacct-username-help&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; that several communities have configured will no longer be used. If communities want to customize the guidance shown in the new popover, they can instead edit the following messages: &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;createacct-username-policy-popover-bullet1&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt;, &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;createacct-username-policy-popover-bullet2&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt;, and &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;createacct-username-policy-popover-bullet3&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt;. [https://phabricator.wikimedia.org/T430604]
* Later this week, the [[mw:Special:MyLanguage/Help:Extension:CodeMirror|CodeMirror syntax highlighter]] will offer [[w:en:Theme (computing)|themes]]. The themes can be picked from a dropdown menu in the full [[mw:Special:MyLanguage/Help:Extension:CodeMirror#CodeMirror preferences|CodeMirror preferences]] dialog. For wikitext, available themes are default, colorblind-friendly (previously the colorblind preference option on [[Special:Preferences#mw-prefsection-editing]]) and no-highlighting. For code languages (i.e., CSS/JavaScript/JSON/Vue/Lua), there are several themes available. These same themes will eventually be available for wikitext, too. [https://phabricator.wikimedia.org/T163533]
* From now on, wikis can restrict editing in the &quot;User&quot; namespace to only the page owner and certain user groups. [[mw:Special:MyLanguage/Manual:$wgRestrictUserPageEditing|Read the configuration documentation]] to learn more.

'''Updates for editors'''
* The [[mw:Special:MyLanguage/Readers/Reader Experience|Reader Experience team]] has developed a [https://82db7c8d4b.catalyst.wmcloud.org/w/index.php?title=Regent%27s_Park&amp;uselang=de patch demo] that wraps the page toolbar onto two lines when there is not enough horizontal space for all the buttons. This aims to reduce crowding in the Vector 2022 toolbar, which can occur on some language Wikipedias at certain screen widths. [https://phabricator.wikimedia.org/T429518]
* The Reader Experience team is planning to launch [[mw:Special:MyLanguage/Readers/Reader Experience/Reading lists|Reading Lists]], a [[m:Special:MyLanguage/Community Wishlist Survey 2021/Mobile and apps/Have Apps reading lists available on Destop/Mobile|Community Wishlist item]], which is currently available to try in beta, as a full feature in September. Before then, volunteer translator help is needed for [https://translatewiki.net/w/i.php?title=Special%3ATranslate&amp;group=ext-readinglists&amp;filter=&amp;action=translate string translations] into a number of languages. The feature supports reading and learning goals on Wikipedia.
* Next week, the table of contents on Wikimedia Commons file pages will be improved by consolidating the file page table of contents with the page table of contents. This will make it easier to understand a file page’s structure, navigate to specific sections, and share links to individual sections. [https://phabricator.wikimedia.org/T332644]

For example, an issue where some [[w:TIFF|TIFF]] images failed to load after clicking their thumbnail, causing a broken image to be displayed instead of the full-size image, has now been fixed. [https://phabricator.wikimedia.org/T429326]

'''Updates for technical contributors'''
* The variable and function selector in AbuseFilter has been updated to support search and autocomplete. It will allow filter maintainers to find the desired variable or function more quickly. [https://phabricator.wikimedia.org/T323698]
* The MJPEG and VP8 formats are removed from the video player. The MP4 format (MPEG-4 Part 2) is added instead, which provides higher quality videos to older iPhone devices. It may take a few weeks to retroactively update all existing videos. The default format for modern devices stays the same (VP9/WebM). [https://phabricator.wikimedia.org/T358266]

'''Tech News'''
* Because of the [[w:en:Christmas and holiday season|holidays]] the next issue of Tech News will be sent out on 11 January 2021.

'''Recent changes'''
* The &lt;code&gt;&lt;nowiki&gt;{{citation needed}}&lt;/nowiki&gt;&lt;/code&gt; template shows when a statement in a Wikipedia article needs a source. If you click on it when you edit with the visual editor there is a popup that explains this. Now it can also show the reason and when it was added. [https://phabricator.wikimedia.org/T270107]

'''Changes later this week'''
* There is no new MediaWiki version this week or next week.

'''Future changes'''
* You can [[m:WMDE Technical Wishes/Geoinformation/Ideas|propose and discuss]] what technical improvements should be done for geographic information. This could be coordinates, maps or other related things.
* Some wikis use [[mw:Writing systems/LanguageConverter|LanguageConverter]] to switch between writing systems or variants of a language. This can only be done for the entire page. There will be a &lt;code&gt;&lt;nowiki&gt;&lt;langconvert&gt;&lt;/nowiki&gt;&lt;/code&gt; tag that can convert a piece of text on a page. [https://phabricator.wikimedia.org/T263082]
*  Oversighters and stewards can hide entries in [[Special:AbuseLog|Special:AbuseLog]]. They can soon hide multiple entries at once using checkboxes. This works like hiding normal edits. It will happen in early January. [https://phabricator.wikimedia.org/T260904]

'''Recent changes'''
* You can choose to be reminded when you have not added an edit summary. This can be done in your preferences. This could conflict with the [[:w:en:CAPTCHA|CAPTCHA]]. This has now been fixed. [https://phabricator.wikimedia.org/T12729]
* You can link to specific log entries. You can get these links for example by clicking the timestamps in the log. Until now, such links to private log entries showed no entry even if you had permission to view private log entries. The links now show the entry. [https://phabricator.wikimedia.org/T269761]
* Admins can use the [[:mw:Special:MyLanguage/Extension:AbuseFilter|abuse filter tool]] to automatically prevent bad edits. Three changes happened last week:
** The filter editing interface now shows syntax errors while you type. This is similar to JavaScript pages. It also shows a warning for regular expressions that match the empty string. New warnings will be added later. [https://phabricator.wikimedia.org/T187686]
** [[m:Special:MyLanguage/Meta:Oversighters|Oversighters]] can now hide multiple filter log entries at once using checkboxes on [[Special:AbuseLog]]. This is how the usual revision deletion works. [https://phabricator.wikimedia.org/T260904]
** When a filter matches too many actions after it has been changed it is &quot;throttled&quot;. The most powerful actions are disabled. This is to avoid many editors getting blocked when an administrator made a mistake. The administrator will now get a notification about this &quot;throttle&quot;.
* [[File:Octicons-tools.svg|15px|link=|Advanced item]] There is a new tool to [https://skins.wmflabs.org/?#/add build new skins].

[https://lists.wikimedia.org/pipermail/wikitech-l/2020-December/094130.html]

Setting the &lt;code&gt;watchlist&lt;/code&gt; to &lt;code&gt;watch&lt;/code&gt; will still work. This is to reduce the size of the watchlist data in the database. [https://phabricator.wikimedia.org/T258108]
* [[File:Octicons-tools.svg|15px|link=|Advanced item]] [[mw:Special:MyLanguage/Extension:Scribunto|Scribunto's]] [[:mw:Extension:Scribunto/Lua reference manual#File metadata|file metadata]] now includes length. [https://phabricator.wikimedia.org/T209679]

* [[m:Special:MyLanguage/MassMessage|MassMessage]] posts could be automatically timestamped in the future. This is because MassMessage senders can now send pages using MassMessage.

'''Problems'''
* [[:w:en:IPv6|IPv6 addresses]] were written in lowercase letters in diffs. This caused dead links since [[Special:Contributions|Special:Contributions]] only accepted uppercase letters for the IPs. This has been fixed. [https://phabricator.wikimedia.org/T272225]

'''Changes later this week'''
* You can soon use Wikidata to link to pages on the multilingual Wikisource. [https://phabricator.wikimedia.org/T138332]
* Often editors use a &quot;non-breaking space&quot; to make a gap between two items when reading but still show them together. This can be used to avoid a line break. You will now be able to add new ones via the special character tool in the 2010, 2017, and visual editors. The character will be shown in the visual editor as a space with a grey background. [https://phabricator.wikimedia.org/T70429][https://phabricator.wikimedia.org/T96666]

'''Problems'''
* There were problems with recent versions of MediaWiki.  Because the updates caused problems the developers rolled back to an earlier version. Some updates and new functions will come later than planned. [https://lists.wikimedia.org/pipermail/wikitech-l/2021-February/094255.html][https://lists.wikimedia.org/pipermail/wikitech-l/2021-February/094271.html]
* Some services will not work for a short period of time from 07:00 UTC on 17 February. There might be problems with new [[m:Special:MyLanguage/Wikimedia URL Shortener|short links]], new translations, new notifications, adding new items to your [[mw:Reading/Reading Lists|reading lists]] or recording [[:w:en:Email#Tracking of sent mail|email bounces]]. This is because of database maintenance. [https://phabricator.wikimedia.org/T273758]

'''Recent changes'''
* [[mw:Special:MyLanguage/Content translation/Section translation|Section translation]] now works on Bengali Wikipedia. It helps mobile editors translate sections of articles. It will come to more wikis later. The first focus is active wikis with a smaller number of articles. You can [https://sx.wmflabs.org/index.php/Main_Page test it] and [[mw:Talk:Content translation/Section translation|leave feedback]].
* [[mw:Special:MyLanguage/Help:Extension:FlaggedRevs|Flagged revisions]] now give admins the review right. [https://phabricator.wikimedia.org/T275293]
* When someone links to a Wikipedia article on Twitter this will now show a preview of the article. [https://phabricator.wikimedia.org/T276185]

'''Problems'''
* Many graphs have [[:w:en:JavaScript|JavaScript]] errors. Graph editors can check their graphs in their browser's developer console after editing. [https://phabricator.wikimedia.org/T275833]

'''Changes later this week'''
* [[File:Octicons-sync.svg|12px|link=|Recurrent item]] The [[mw:MediaWiki 1.36/wmf.34|new version]] of MediaWiki will be on test wikis and MediaWiki.org from {{#time:j xg|2021-03-09|en}}.

* The [[mw:Talk pages project/New discussion|New Discussion]] tool will soon be a new [[mw:Special:MyLanguage/Extension:DiscussionTools|discussion tools]] beta feature for on most Wikipedias. The goal is to make it easier to start new discussions. [https://phabricator.wikimedia.org/T275257]

'''Future changes'''
* There will be a number of changes to make it easier to work with templates. Some will come to the first wikis in March. Other changes will come to the first wikis in June. This is both for those who use templates and those who create or maintain them. You can [[:m:WMDE Technical Wishes/Templates|read more]].
* [[m:WMDE Technical Wishes/ReferencePreviews|Reference Previews]] will become a default feature on some wikis on 17 March. They will share a setting with [[mw:Page Previews|Page Previews]]. If you prefer the Reference Tooltips or Navigation-Popups gadget you can keep using them. If so Reference Previews won't be shown. [https://phabricator.wikimedia.org/T271206][https://meta.wikimedia.org/wiki/Talk:WMDE_Technical_Wishes/ReferencePreviews]
* New JavaScript-based functions will not work in [[:w:en:Internet Explorer 11|Internet Explorer 11]]. This is because Internet Explorer is an old browser that doesn't work with how JavaScript is written today. Everything that works in Internet Explorer 11 today will continue working in Internet Explorer for now. You can [[mw:Compatibility/IE11|read more]].

* Wikis that are part of the [[mw:Special:MyLanguage/Reading/Web/Desktop Improvements|desktop improvements]] project can now use a new [[mw:Special:MyLanguage/Reading/Web/Desktop Improvements/Features/Search|search function]]. The desktop improvements and the new search will come to more wikis later. You can also [[mw:Reading/Web/Desktop Improvements#Deployment plan and timeline|test it early]].

'''Problems'''
* Due to [[phab:T276968|database issues]] the [https://meta.wikimedia.beta.wmflabs.org Wikimedia Beta Cluster] was read-only for over a day.

'''Changes later this week'''

'''Future changes'''
* You can add a [[:w:en:Newline|newline]] or [[:w:en:Carriage return|carriage return]] character to a custom signature if you use a template. There is a proposal to not allow them in the future. This is because they can cause formatting problems. [https://www.mediawiki.org/wiki/New_requirements_for_user_signatures#Additional_proposal_(2021)][https://phabricator.wikimedia.org/T272322]

* [[File:Octicons-tools.svg|15px|link=|Advanced item]] You can use [https://quarry.wmflabs.org/ Quarry] for [[:w:en:SQL|SQL]] queries to the [[wikitech:Wiki replicas|Wiki Replicas]].

'''Recent changes'''
* There is a [[mw:Wikipedia for KaiOS|Wikipedia app]] for [[:w:en:KaiOS|KaiOS]] phones. They don't have a touch screen so readers navigate with the phone keys. There is now a [https://wikimedia.github.io/wikipedia-kaios/sim.html simulator] so you can see what it looks like.
* The [[mw:Special:MyLanguage/Talk pages project/Replying|reply tool]] and [[mw:Special:MyLanguage/Talk pages project/New discussion|new discussion tool]] are now available as the &quot;{{int:discussiontools-preference-label}}&quot; [[Special:Preferences#mw-prefsection-betafeatures|beta feature]] in almost all wikis except German Wikipedia.

'''Future changes'''
* [[mw:Special:MyLanguage/Extension:FlaggedRevs|Flagged revisions]] will no longer have multiple tags like &quot;tone&quot; or &quot;depth&quot;. It will also only have one tier. This was changed because very few wikis used these features and they make the tool difficult to maintain. [https://phabricator.wikimedia.org/T185664][https://phabricator.wikimedia.org/T277883]
* [[File:Octicons-tools.svg|15px|link=|Advanced item]] Gadgets and user scripts can access variables about the current page in JavaScript.

* The Wikimedia movement uses [[:mw:Special:MyLanguage/Phabricator|Phabricator]] for technical tasks. This is where we collect technical suggestions, bugs and what developers are working on. The company behind Phabricator will stop working on it. This will not change anything for the Wikimedia movement now. It could lead to changes in the future.

* Searching on Wikipedia will find more results in some languages. This is mainly true for when those who search do not use the correct [[:w:en:Diacritic|diacritics]] because they are not seen as necessary in that language. For example searching for &lt;code&gt;Bedusz&lt;/code&gt; doesn't find &lt;code&gt;Będusz&lt;/code&gt; on German Wikipedia.

There is a short-term fix that can be added to your local wiki's Common.css page, which is explained at [[phab:T287701|T287701]].

'''Problems'''
* Last week, all wikis had slow access or no access for 30 minutes. There was a problem with generating dynamic lists of articles on the Russian Wikinews, due to the bulk import of 200,000+ new articles over 3 days, which led to database problems.

'''Recent changes'''
* You can add language links in the sidebar in the [[mw:Special:MyLanguage/Reading/Web/Desktop Improvements|new Vector skin]] again. You do this by connecting the page to a Wikidata item. The new Vector skin has moved the language links but the new language selector cannot add language links yet. [https://phabricator.wikimedia.org/T287206]

'''Problems'''
* There was a problem on wikis which use the Translate extension. Translations were not updated or were replaced with the English text. The problems have been fixed. [https://phabricator.wikimedia.org/T288700][https://phabricator.wikimedia.org/T288683][https://phabricator.wikimedia.org/T288719]

'''Changes later this week'''
* A [[mw:Help:Tags|revision tag]] will soon be added to edits that add links to [[mw:Special:MyLanguage/Extension:Disambiguator|disambiguation pages]]. This is because these links are usually added by accident. The tag will allow editors to easily find the broken links and fix them. If your wiki does not like this feature, it can be [[mw:Help:Tags#Deleting a tag added by the software|hidden]]. [https://phabricator.wikimedia.org/T287549]
*Would you like to help improve the information about tools? Would you like to attend or help organize a small virtual meetup for your community to discuss the list of tools?

We are also looking for feedback [[m:Talk:Toolhub/The Quality Signal Sessions#Discussion topic for &quot;Quality Signal Sessions: The Tool Maintainers edition&quot;|from tool maintainers]] on some specific questions.
* In the past, edits to any page in your user talk space ignored your [[mw:Special:MyLanguage/Help:Notifications#mute|mute list]], e.g. sub-pages. Starting this week, this is only true for edits to your talk page. [https://phabricator.wikimedia.org/T288112]

Features will be available for newcomers starting on 20 September 2021.
* MediaWiki had a feature that would highlight local links to short articles in a different style. Each user could pick the size at which &quot;stubs&quot; would be highlighted. This feature was very bad for performance, and following a consultation, has been removed. [https://phabricator.wikimedia.org/T284917]
* A technical change was made to the MonoBook skin to allow for easier maintenance and upkeep. This has resulted in some minor changes to HTML that make MonoBook's HTML consistent with other skins.

Bot operators using Pywikibot can follow [[phab:T291202|T291202]] for progress on a fix, and should plan to upgrade to 6.6.1 when it is released.

'''Problems'''
* MediaWiki 1.38-wmf.11 was scheduled to be deployed on some wikis last week. The deployment was delayed because of unexpected problems.

'''Changes later this week'''
* [[File:Octicons-sync.svg|12px|link=|Recurrent item]] The [[mw:MediaWiki 1.38/wmf.12|new version]] of MediaWiki will be on test wikis and MediaWiki.org from {{#time:j xg|2021-12-07|en}}. It will be on non-Wikipedia wikis and some Wikipedias from {{#time:j xg|2021-12-08|en}}. It will be on all wikis from {{#time:j xg|2021-12-09|en}} ([[mw:MediaWiki 1.38/Roadmap|calendar]]).
* At all Wikipedias, a Mentor Dashboard is now available at &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;Special:MentorDashboard&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt;. It allows registered mentors, who take care of newcomers' first steps, to monitor their assigned newcomers' activity. It is part of the [[mw:Special:MyLanguage/Growth/Feature summary|Growth features]]. You can learn more about [[mw:Special:MyLanguage/Growth/Communities/How_to_configure_the_mentors%27_list|activating the mentor list]] on your wiki and about [[mw:Special:MyLanguage/Growth/Mentor dashboard|the mentor dashboard project]].

'''Recent changes'''
* There are now default [[m:Special:MyLanguage/Help:Namespace#Other_namespace_aliases|short aliases]] for the &quot;Project:&quot; namespace on most wikis. E.g. On Wikibooks wikis, &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;[[WB:]]&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; will go to the local language default for the &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;[[Project:]]&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; namespace. This change is intended to help the smaller communities have easy access to this feature. Additional local aliases can still be requested via [[m:Special:MyLanguage/Requesting wiki configuration changes|the usual process]]. [https://phabricator.wikimedia.org/T293839]

** The user group &lt;code&gt;oversight&lt;/code&gt; will be renamed &lt;code&gt;suppress&lt;/code&gt;. This is for [[phab:T109327|technical reasons]]. This is the technical name. It doesn't affect what you call the editors with this user right on your wiki. This is planned to happen in three weeks. You can comment [[phab:T112147|in Phabricator]] if you have objections. As usual, these labels can be translated on translatewiki ([[phab:T112147|direct links are available]]) or by administrators on your wiki.

'''Events'''
* You can vote on proposals in the [[m:Special:MyLanguage/Community Wishlist Survey 2022|Community Wishlist Survey]] between 28 January and 11 February. The survey decides what the [[m:Special:MyLanguage/Community Tech|Community Tech team]] will work on.

[https://phabricator.wikimedia.org/T25020]
* At Wikipedias, all new accounts now get the [[mw:Special:MyLanguage/Growth/Feature_summary|Growth features]] by default when creating an account. Communities are encouraged to [[mw:Special:MyLanguage/Help:Growth/Tools/Account_creation|update their help resources]]. Previously, only 80% of new accounts would get the Growth features. A few Wikipedias remain unaffected by this change. [https://phabricator.wikimedia.org/T301820]
* You can now prevent specific images that are used in a page from appearing in other locations, such as within PagePreviews or Search results. This is done with the markup &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;class=notpageimage&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt;.

* Mentors using the [[mw:Special:MyLanguage/Growth/Mentor_dashboard|Growth Mentor dashboard]] will now see newcomers assigned to them who have made at least one edit, up to 200 edits. Previously, all newcomers assigned to the mentor were visible on the dashboard, even ones without any edit or ones who made hundred of edits.

'''Future changes'''
* Working with templates will become easier. [[m:WMDE_Technical_Wishes/Templates|Several improvements]] are planned for March 9 on most wikis and on March 16 on English Wikipedia. The improvements include: Bracket matching, syntax highlighting colors, finding and inserting templates, and related visual editor features.
* If you are a template developer or an interface administrator, and you are intentionally overriding or using the default CSS styles of user feedback boxes (the classes: &lt;code dir=ltr&gt;successbox, messagebox, errorbox, warningbox&lt;/code&gt;), please note that these classes and associated CSS will soon be removed from MediaWiki core. This is to prevent problems when the same class-names are also used on a wiki. Please let us know by commenting at [[phab:T300314]] if you think you might be affected.

'''Tech News'''
* Because of the [[w:en:Christmas and holiday season|holidays]] the next issue of Tech News will be sent out on 9 January 2023.

'''Recent changes'''
* On a user's contributions page, you can filter it for edits with a tag like 'reverted'. Now, you can also filter for all edits that are not tagged like that. This was part of a Community Wishlist 2022 request. [https://phabricator.wikimedia.org/T119072]
* [[File:Octicons-tools.svg|15px|link=|alt=|Advanced item]] A new function has been used for gadget developers to add content underneath the title on article pages. This is considered a stable API that should work across all skins. [[mw:Special:MyLanguage/ResourceLoader/Core_modules#addSubtitle|Documentation is available]]. [https://phabricator.wikimedia.org/T316830]
* [[File:Octicons-tools.svg|15px|link=|alt=|Advanced item]] [[test2wiki:|One of our test wikis]] is now being served from a new infrastructure powered by [[w:Kubernetes|Kubernetes]] ([[wikitech:MediaWiki On Kubernetes|read more]]). More Wikis will switch to this new infrastructure in early 2023. Please test and let us know of any issues. [https://phabricator.wikimedia.org/T290536]

'''Problems'''
* Last week, all wikis had no edit access for 9 minutes. This was caused by a database problem. [https://wikitech.wikimedia.org/wiki/Incidents/2022-12-13_sessionstore]

'''Changes later this week'''
* There is no new MediaWiki version this week or next week.
* The word &quot;{{int:discussiontools-replybutton}}&quot; is very short in some languages, such as Arabic (&quot;&lt;bdi lang=&quot;ar&quot;&gt;ردّ&lt;/bdi&gt;&quot;). This makes the {{int:discussiontools-preference-label}} button on talk pages difficult to use. An arrow icon will be added to those languages. This will only be visible to editors who have the [[Special:Preferences#mw-prefsection-betafeatures|Beta Feature]] turned on. [https://www.mediawiki.org/wiki/Talk_pages_project/Usability#Status] [https://phabricator.wikimedia.org/T323537]

'''Future changes'''
* Edits can be automatically &quot;tagged&quot; by the system software or the {{int:Abusefilter}} system. Those tags link to a help page about the tags. Soon they will also link to Recent Changes to let you see other edits tagged this way. This was a Community Wishlist 2022 request. [https://phabricator.wikimedia.org/T301063]
* The Trust &amp; Safety tools team [[m:Special:MyLanguage/Private Incident Reporting System/Timeline and Updates|have shared new plans]] for building the Private Incident Reporting System. The system will make it easier for editors to ask for help if they are harassed or abused. 
* [[m:Special:MyLanguage/Community Wishlist Survey 2021/Real Time Preview for Wikitext|Realtime Preview for Wikitext]] is coming out of beta as an enabled feature for every user of the 2010 Wikitext [[mw:Special:MyLanguage/Editor|editor]] in the week of January 9, 2023. It will be available to use via the toolbar in the 2010 Wikitext editor. The feature was the 4th most popular wish of the Community Wishlist Survey 2021.

'''Events'''
* You can now [[mw:Special:MyLanguage/Wikimedia Hackathon 2023/Participate|register for the Wikimedia Hackathon 2023]], taking place on May 19–21 in Athens, Greece. You can also apply for a scholarship until January 14th.

* The Vega software that creates data visualizations in pages, such as graphs, will be upgraded to the newest version in the future.

== Tech News: 2023-28 ==

&lt;section begin=&quot;technews-2023-W28&quot;/&gt;&lt;div class=&quot;plainlinks&quot;&gt;
Latest '''[[m:Special:MyLanguage/Tech/News|tech news]]''' from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. [[m:Special:MyLanguage/Tech/News/2023/28|Translations]] are available.

'''Recent changes'''
* The [[:mw:Special:MyLanguage/Structured Data Across Wikimedia/Section-level Image Suggestions|Section-level Image Suggestions feature]] has been deployed on seven Wikipedias (Portuguese, Russian, Indonesian, Catalan, Hungarian, Finnish and Norwegian Bokmål). The feature recommends images for articles on contributors' watchlists that are a good match for individual sections of those articles.
* [[:m:Special:MyLanguage/Global AbuseFilter|Global abuse filters]] have been enabled on all Wikimedia projects, except English and Japanese Wikipedias (who opted out). This change was made following a [[:m:Requests for comment/Make global abuse filters opt-out|global request for comments]]. [https://phabricator.wikimedia.org/T341159]
* [[{{#special:BlockedExternalDomains}}]] is a new tool for administrators to help fight spam. It provides a clearer interface for blocking plain domains (and their subdomains), is more easily searchable, and is faster for the software to process for each edit on the wiki. It does not support regex (for complex cases), nor URL path-matching, nor the [[MediaWiki:Spam-whitelist|MediaWiki:Spam-whitelist]], but otherwise it replaces most of the functionalities of the existing [[MediaWiki:Spam-blacklist|MediaWiki:Spam-blacklist]]. There is a Python script to help migrate all simple domains into this tool, and more feature details, within [[mw:Special:MyLanguage/Manual:BlockedExternalDomains|the tool's documentation]]. It is available at all wikis except for Meta-wiki, Commons, and Wikidata. [https://phabricator.wikimedia.org/T337431]
* The WikiEditor extension was updated. It includes some of the most frequently used features of wikitext editing. In the past, many of its messages could only be translated by administrators, but now all regular translators on translatewiki can translate them. Please check [https://translatewiki.net/wiki/Special:MessageGroupStats?group=ext-wikieditor&amp;messages=&amp;x=D#sortable:0=asc the state of WikiEditor localization into your language], and if the &quot;Completion&quot; for your language shows anything less than 100%, please complete the translation. See [https://lists.wikimedia.org/hyperkitty/list/wikitech-ambassadors@lists.wikimedia.org/thread/D4YELU2DXMZ75PGELUOKXXMFF3FH45XA/ a more detailed explanation].

'''Changes later this week'''
* [[File:Octicons-sync.svg|12px|link=|alt=|Recurrent item]] The [[mw:MediaWiki 1.41/wmf.17|new version]] of MediaWiki will be on test wikis and MediaWiki.org from {{#time:j xg|2023-07-11|en}}. It will be on non-Wikipedia wikis and some Wikipedias from {{#time:j xg|2023-07-12|en}}. It will be on all wikis from {{#time:j xg|2023-07-13|en}} ([[mw:MediaWiki 1.41/Roadmap|calendar]]).
* The default protocol of [[{{#special:LinkSearch}}]] and API counterparts has changed from http to both http and https. [https://phabricator.wikimedia.org/T14810]
* [[{{#special:LinkSearch}}]] and its API counterparts will now search for all of the URL provided in the query. It used to be only the first 60 characters. This feature was requested fifteen years ago. [https://phabricator.wikimedia.org/T17218]

'''Future changes'''
* There is an experiment with a [[:w:en:ChatGPT|ChatGPT]] plugin. This is to show users where the information is coming from when they read information from Wikipedia. It has been tested by Wikimedia Foundation staff and other Wikimedians. Soon all ChatGPT plugin users can use the Wikipedia plugin. This is the same plugin which was mentioned in [[m:Special:MyLanguage/Tech/News/2023/20|Tech News 2023/20]]. [https://meta.wikimedia.org/wiki/Wikimedia_Foundation_Annual_Plan/2023-2024/Draft/Future_Audiences#FA2.2_Conversational_AI]
* There is an ongoing discussion on a [[m:Special:MyLanguage/Third-party resources policy|proposed Third-party resources policy]]. The proposal will impact the use of third-party resources in gadgets and userscripts. Based on the ideas received so far, policy includes some of the risks related to user scripts and gadgets loading third-party resources, some best practices and exemption requirements such as code transparency and inspectability. Your feedback and suggestions are warmly welcome until July 17, 2023 on [[m:Talk:Third-party resources policy|on the policy talk page]].

'''Recent changes'''
* [[File:Octicons-tools.svg|12px|link=|alt=|Advanced item]] We are now serving 1% of all global user traffic from [[w:en:Kubernetes|Kubernetes]] (you can [[wikitech:MediaWiki On Kubernetes|read more technical details]]). We are planning to increment this percentage regularly. You can [[phab:T290536|follow the progress of this work]]. 

'''Changes later this week'''
* [[File:Octicons-sync.svg|12px|link=|alt=|Recurrent item]] The [[mw:MediaWiki 1.41/wmf.18|new version]] of MediaWiki will be on test wikis and MediaWiki.org from {{#time:j xg|2023-07-18|en}}. It will be on non-Wikipedia wikis and some Wikipedias from {{#time:j xg|2023-07-19|en}}. It will be on all wikis from {{#time:j xg|2023-07-20|en}} ([[mw:MediaWiki 1.41/Roadmap|calendar]]).
* [[File:Octicons-tools.svg|12px|link=|alt=|Advanced item]] MediaWiki [[mw:Special:MyLanguage/Help:System_message|system messages]] will now look for available local fallbacks, instead of always using the default fallback defined by software. This means wikis no longer need to override each language on the [[mw:Special:MyLanguage/Manual:Language#Fallback_languages|fallback chain]] separately. For example, English Wikipedia doesn't have to create &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;en-ca&lt;/code&gt;&lt;/bdi&gt; and &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;en-gb&lt;/code&gt;&lt;/bdi&gt; subpages with a transclusion of the base pages anymore. This makes it easier to maintain local overrides. [https://phabricator.wikimedia.org/T229992]
* [[File:Octicons-tools.svg|12px|link=|alt=|Advanced item]] The &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;action=growthsetmentorstatus&lt;/code&gt;&lt;/bdi&gt; API will be deprecated with the new MediaWiki version. Bots or scripts calling that API should use the &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;action=growthmanagementorlist&lt;/code&gt;&lt;/bdi&gt; API now.

'''Recent changes'''
* [[File:Octicons-gift.svg|12px|link=|alt=|Wishlist item]] As part of the changes for the [[m:Community Wishlist Survey 2022/Better diff handling of paragraph splits|better diff handling of paragraph splits]], improved detection of splits is being rolled out. Over the last two weeks, we deployed this support to [[wikitech:Deployments/Train#Groups|group0]] and group1 wikis. This week it will be deployed to group2 wikis. [https://phabricator.wikimedia.org/T341754]
* [[File:Octicons-gift.svg|12px|link=|alt=|Wishlist item]] All [[{{#special:Contributions}}]] pages now show the user's local edit count and the account's creation date. [https://phabricator.wikimedia.org/T324166]
* Wikisource users can now use the &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;prpbengalicurrency&lt;/code&gt;&lt;/bdi&gt; label to denote Bengali currency characters as page numbers inside the &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;&lt;pagelist&gt;&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; tag.  [https://phabricator.wikimedia.org/T268932]
* Two preferences have been relocated. The preference &quot;{{int:visualeditor-preference-visualeditor}}&quot; is now shown on the [[Special:Preferences#mw-prefsection-editing|&quot;{{int:prefs-editing}}&quot; tab]] at all wikis. Previously it was shown on the &quot;{{int:prefs-betafeatures}}&quot; tab at some wikis. The preference &quot;{{int:visualeditor-preference-newwikitexteditor-enable}}&quot; is now also shown on the &quot;{{int:prefs-editing}}&quot; tab at all wikis, instead of the &quot;{{int:prefs-betafeatures}}&quot; tab. [https://phabricator.wikimedia.org/T335056][https://phabricator.wikimedia.org/T344158]

'''Changes later this week'''
* [[File:Octicons-sync.svg|12px|link=|alt=|Recurrent item]] The [[mw:MediaWiki 1.41/wmf.24|new version]] of MediaWiki will be on test wikis and MediaWiki.org from {{#time:j xg|2023-08-29|en}}. It will be on non-Wikipedia wikis and some Wikipedias from {{#time:j xg|2023-08-30|en}}. It will be on all wikis from {{#time:j xg|2023-08-31|en}} ([[mw:MediaWiki 1.41/Roadmap|calendar]]).
* [[File:Octicons-tools.svg|12px|link=|alt=|Advanced item]] New signups for a Wikimedia developer account will start being pushed towards &lt;bdi lang=&quot;en&quot; dir=&quot;ltr&quot;&gt;[https://idm.wikimedia.org/ idm.wikimedia.org]&lt;/bdi&gt;, rather than going via Wikitech. [[wikitech:IDM|Further information about the new system is available]].
* All right-to-left language wikis, plus Korean, Armenian, Ukrainian, Russian, and Bulgarian Wikipedias, will have a link in the sidebar that provides a short URL of that page, using the [[m:Special:MyLanguage/Wikimedia URL Shortener|Wikimedia URL Shortener]]. This feature will come to more wikis in future weeks. [https://phabricator.wikimedia.org/T267921]

'''Future changes'''
* The removal of the [[mw:Special:MyLanguage/Extension:DoubleWiki|DoubleWiki extension]] is being discussed. This extension currently allows Wikisource users to view articles from multiple language versions side by side when the &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;=&gt;&lt;/code&gt;&lt;/bdi&gt; symbol next to a specific language edition is selected. Comments on this are welcomed at [[phab:T344544|the phabricator task]].
* A proposal has been made to merge the second hidden-categories list (which appears below the wikitext editing form) with the main list of categories (which is further down the page). [[phab:T340606|More information is available on Phabricator]]; feedback is welcome!

[https://phabricator.wikimedia.org/T342115]
* When you are logged in on one Wikimedia wiki and visit a different Wikimedia wiki, the system tries to log you in there automatically. This has been unreliable for a long time. You can now visit the login page to make the system try extra hard. If you feel that made logging in better or worse than it used to be, your feedback is appreciated.

* Listings on category pages are sorted on each wiki for that language using a [[:w:en:International Components for Unicode|library]]. For a brief period on 2 November, changes to categories will not be sorted correctly for many languages. This is because the developers are upgrading to a new version of the library. They will then use a script to fix the existing categories. This will take a few hours or a few days depending on how big the wiki is.

There are [[mw:Special:MyLanguage/Reading/Web/Desktop Improvements/Features/Loading Vector 2010 scripts|more technical details]] available. Interface administrators who foresee this leading to lots of technical support questions may wish to send a mass message to your community, as was done on French Wikipedia.

[[File:Talk_pages_default_look_(April_2023).jpg|thumb|alt=Screenshot of the visual improvements made on talk pages|Example of a talk page with the new design, in French.]]
* The appearance of talk pages changed for the following wikis: {{int:project-localized-name-azwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-bnwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-dewiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-fawiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-hewiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-hiwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-idwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-kowiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-nlwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-ptwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-rowiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-thwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-trwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-ukwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-viwiki/en}}. These wikis participated to a test, where 50% of users got the new design, for one year. As this test [[Mw:Special:MyLanguage/Talk pages project/Usability/Analysis|gave positive results]], the new design is deployed on these wikis as the default design. It is possible to opt-out these changes [[Special:Preferences#mw-prefsection-editing|in user preferences]] (&quot;{{int:discussiontools-preference-visualenhancements}}&quot;). The deployment will happen at all wikis in the coming weeks. [https://phabricator.wikimedia.org/T341491]
* Seven new wikis have been created: 
** a {{int:project-localized-name-group-wikipedia}} in [[d:Q33014|Betawi]] ([[w:bew:|&lt;code&gt;w:bew:&lt;/code&gt;]]) [https://phabricator.wikimedia.org/T357866]

Initially, this feature will notify you of added or deleted messages in these groups. [https://phabricator.wikimedia.org/T348501]
* Dark mode is now available on all wikis, on mobile web for logged-in users who opt into the [[Special:MobileOptions|advanced mode]]. This is the early release of the feature. Technical editors are invited to [https://night-mode-checker.wmcloud.org/ check for accessibility issues on wikis]. See [[mw:Special:MyLanguage/Reading/Web/Accessibility for reading/Updates/2024-04|more detailed guidelines]].

'''Problems'''
* [[mw:Special:MyLanguage/Help:Extension:Kartographer|Kartographer]] maps can use an alternative visual style without labels, by using &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;mapstyle=&quot;osm&quot;&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt;. This wasn't working in previews, creating the wrong impression that it wasn't supported. This has now been fixed. [https://phabricator.wikimedia.org/T362531]

'''Changes later this week'''

'''Recent changes'''
* On Wikisource there is a special page listing pages of works without corresponding scan images. Now you can use the new magic word &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;__EXPECTWITHOUTSCANS__&lt;/code&gt;&lt;/bdi&gt; to exclude certain pages (list of editions or translations of works) from that list. [https://phabricator.wikimedia.org/T344214]
* If you use the [[Special:Preferences#mw-prefsection-editing|user-preference]] &quot;{{int:tog-uselivepreview}}&quot;, then the template-page feature &quot;{{int:Templatesandbox-editform-legend}}&quot; will now also work without reloading the page. [https://phabricator.wikimedia.org/T136907]
* [[mw:Special:Mylanguage/Extension:Kartographer|Kartographer]] maps can now specify an alternative text via the &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;alt=&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; attribute. This is identical in usage to the &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;alt=&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; attribute in the [[mw:Special:MyLanguage/Help:Images#Syntax|image and gallery syntax]]. An exception for this feature is wikis like Wikivoyage where the miniature maps are interactive. [https://phabricator.wikimedia.org/T328137]
* The old [[mw:Special:MyLanguage/Extension:GuidedTour|Guided Tour]] for the &quot;[[mw:Special:MyLanguage/Edit Review Improvements/New filters for edit review|New Filters for Edit Review]]&quot; feature has been removed. It was created in 2017 to show people with older accounts how the interface had changed, and has now been seen by most of the intended people. [https://phabricator.wikimedia.org/T217451]

* [[File:Octicons-tools.svg|12px|link=|alt=|Advanced item]] The [[{{#special:search}}]] results page will now use CSS flex attributes, for better accessibility, instead of a table. If you have a gadget or script that adjusts search results, you should update your script to the new HTML structure. [https://phabricator.wikimedia.org/T320295]

'''Future changes'''
* In the Vector 2022 skin, main pages will be displayed at full width (like special pages). The goal is to keep the number of characters per line large enough. This is related to the coming changes to typography in Vector 2022. [[mw:Special:MyLanguage/Reading/Web/Accessibility for reading/Updates|Learn more]]. [https://phabricator.wikimedia.org/T357706]

In your existing SQL queries:
*# Replace &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;JOIN pagelinks&lt;/code&gt;&lt;/bdi&gt; with &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;JOIN linktarget&lt;/code&gt;&lt;/bdi&gt; and &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;pl_&lt;/code&gt;&lt;/bdi&gt; with &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;lt_&lt;/code&gt;&lt;/bdi&gt; in the &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;ON&lt;/code&gt;&lt;/bdi&gt; statement

It will change on 22 May in some skins (Timeless, Modern, CologneBlue, Nostalgia, and Monobook). Please test gadgets on your wiki on these skins and [[phab:T13555|report any related problems]] so that they can be resolved before this change is made in all other skins. The developers are also considering the introduction of a [[phab:T337286|Gadget API for adding buttons to section titles]] if that would be helpful to tool creators, and would appreciate any input you have on that.

* [[File:Octicons-tools.svg|12px|link=|alt=|Advanced item]] Some CSS in the Minerva skin has been removed to enable easier community configuration.

* The software used to render SVG files has been updated to a new version, fixing many longstanding bugs in SVG rendering. [https://phabricator.wikimedia.org/T265549]
* [[File:Octicons-tools.svg|12px|link=|alt=|Advanced item]] The HTML used to render all headings [[mw:Heading HTML changes|is being changed to improve accessibility]]. It was changed last week in some skins (Vector legacy and Minerva). Please test gadgets on your wiki on these skins and [[phab:T13555|report any related problems]] so that they can be resolved before this change is made in Vector-2022. The developers are still considering the introduction of a [[phab:T337286|Gadget API for adding buttons to section titles]] if that would be helpful to tool creators, and would appreciate any input you have on that.
* [[File:Octicons-tools.svg|12px|link=|alt=|Advanced item]] The HTML markup used for citations by [[mw:Special:MyLanguage/Parsoid|Parsoid]] changed last week. In places where Parsoid previously added the &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;mw-reference-text&lt;/code&gt;&lt;/bdi&gt; class, Parsoid now also adds the &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;reference-text&lt;/code&gt;&lt;/bdi&gt; class for better compatibility with the legacy parser.

* Starting June 18, the [[mw:Special:MyLanguage/Help:Edit check#ref|Reference Edit Check]] will be deployed to [[phab:T361843|a new set of Wikipedias]]. This feature is intended to help newcomers and to assist edit-patrollers by inviting people who are adding new content to a Wikipedia article to add a citation when they do not do so themselves. During [[mw:Special:MyLanguage/Edit_check#Reference_Check_A/B_Test|a test at 11 wikis]], the number of citations added [https://diff.wikimedia.org/?p=127553 more than doubled] when Reference Check was shown to people.

'''Recent changes'''
* Editors will notice that there have been some changes to the background color of text in the diff view, and the color of the byte-change numbers, last week. These changes are intended to make text more readable in both light mode and dark mode, and are part of a larger effort to increase accessibility. You can share your comments or questions [[mw:Talk:Reading/Web/Accessibility for reading|on the project talkpage]]. [https://phabricator.wikimedia.org/T361717]
* The text colors that are used for visited-links, hovered-links, and active-links, were also slightly changed last week to improve their accessibility in both light mode and dark mode. [https://phabricator.wikimedia.org/T366515]

'''Problems'''
* You can [[mw:Special:MyLanguage/Help:DiscussionTools#Talk pages permalinking|copy permanent links to talk page comments]] by clicking on a comment's timestamp. [[mw:Talk pages project/Permalinks|This feature]] did not always work when the topic title was very long and the link was used as a wikitext link. This has been fixed. Thanks to Lofhi for submitting the bug. [https://phabricator.wikimedia.org/T356196]

'''Recent changes'''
* Over the next three weeks, dark mode will become available for all users, both logged-in and logged-out, starting with the mobile web version. This fulfils one of the [[m:Special:MyLanguage/Community_Wishlist_Survey_2023/Reading/Dark_mode|top-requested community wishes]], and improves low-contrast reading and usage in low-light settings. As part of these changes, dark mode will also work on User-pages and Portals.

[https://phabricator.wikimedia.org/T366364]
* Logged-in users can now set [[m:Special:GlobalPreferences#mw-prefsection-rendering-skin-skin-prefs|global preferences for the text-size and dark-mode]], thanks to a combined effort across Foundation teams. This allows Wikimedians using multiple wikis to set up a consistent reading experience easily, for example by switching between light and dark mode only once for all wikis. [https://phabricator.wikimedia.org/T341278] 
* If you use a very old web browser some features might not work on the Wikimedia wikis. This affects Internet Explorer 11 and versions of Chrome, Firefox and Safari older than 2016. This change makes it possible to use new [[d:Q46441|CSS]] features and to send less code to all readers.

* Wikipedia Admins can customize local wiki configuration options easily using [[mw:Special:MyLanguage/Community Configuration|Community Configuration]]. Community Configuration was created to allow communities to customize how some features work, because each language wiki has unique needs. At the moment, admins can configure [[mw:Special:MyLanguage/Growth/Feature_summary|Growth features]] on their home wikis, in order to better recruit and retain new editors. More options will be provided in the coming months. [https://phabricator.wikimedia.org/T366458]
* Editors interested in language issues that are related to [[w:en:Unicode|Unicode standards]], can now discuss those topics at [[mw:Talk:WMF membership with Unicode Consortium|a new conversation space in MediaWiki.org]]. The Wikimedia Foundation is now a [[mw:Special:MyLanguage/WMF membership with Unicode Consortium|member of the Unicode Consortium]], and the coordination group can collaboratively review the issues discussed and, where appropriate, bring them to the attention of the Unicode Consortium.
* One new wiki has been created: a {{int:project-localized-name-group-wikipedia}} in [[d:Q2891049|Mandailing]] ([[w:btm:|&lt;code&gt;w:btm:&lt;/code&gt;]]) [https://phabricator.wikimedia.org/T368038]

* Thank you to [[mw:MediaWiki Product Insights/Contributor retention and growth/Celebration|all of the authors]] who have contributed to MediaWiki Core. As a result of these contributions, the [[mw:MediaWiki Product Insights/Contributor retention and growth|percentage of authors contributing more than 5 patches has increased by 25% since last year]], which helps ensure the sustainability of the platform for the Wikimedia projects.

'''Problems'''

&lt;section begin=&quot;technews-2024-W29&quot;/&gt;&lt;div class=&quot;plainlinks&quot;&gt;
Latest '''[[m:Special:MyLanguage/Tech/News|tech news]]''' from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. [[m:Special:MyLanguage/Tech/News/2024/29|Translations]] are available.

'''Tech News survey'''
* Please [https://wikimediafoundation.limesurvey.net/758713?lang=en help us to improve Tech News by taking this short survey]. The goal is to better meet the needs of the various types of people who read Tech News. The survey will be open for 3 more days. The survey is covered by [https://foundation.wikimedia.org/wiki/Legal:Tech_News_Survey_2024_Privacy_Statement this privacy statement]. Some translations are available.

'''Recent changes'''
* [[File:Octicons-tools.svg|12px|link=|class=skin-invert|Advanced item]] Wikimedia developers can now officially continue to use both [[mw:Special:MyLanguage/Gerrit|Gerrit]] and [[mw:Special:MyLanguage/GitLab|GitLab]], due to a June 24 decision by the Wikimedia Foundation to support software development on both platforms. Gerrit and GitLab are both code repositories used by developers to write, review, and deploy the software code that supports the MediaWiki software that the wiki projects are built on, as well as the tools used by editors to create and improve content. This decision will safeguard the productivity of our developers and prevent problems in code review from affecting our users. More details are available in the [[mw:GitLab/Migration status|Migration status]] page.
* The Wikimedia Foundation seeks applicants for the [[m:Special:MyLanguage/Product and Technology Advisory Council/Proposal|Product and Technology Advisory Council]] (PTAC). This group will bring technical contributors and Wikimedia Foundation together to co-define a more resilient, future-proof technological platform. Council members will evaluate and consult on the movement's product and technical activities, so that we develop multi-generational projects. We are looking for a range of technical contributors across the globe, from a variety of Wikimedia projects. [[m:Special:MyLanguage/Product and Technology Advisory Council/Proposal#Joining the PTAC as a technical volunteer|Please apply here by August 10]].
* Editors with rollback user-rights who use the Wikipedia App for Android can use the new [[mw:Special:MyLanguage/Wikimedia Apps/Team/Android/Anti Vandalism|Edit Patrol]] features. These features include a new feed of Recent Changes, related links such as Undo and Rollback, and the ability to create and save a personal library of user talk messages to use while patrolling. If your wiki wants to make these features available to users who do not have rollback rights but have reached a certain edit threshold, [[mw:Special:MyLanguage/Wikimedia Apps/Team/Android#Contact us|you can contact the team]]. You can [[diffblog:2024/07/10/ِaddressing-vandalism-with-a-tap-the-journey-of-introducing-the-patrolling-feature-in-the-mobile-app/|read more about this project on Diff blog]].
* Editors who have access to [[m:Special:MyLanguage/The_Wikipedia_Library|The Wikipedia Library]] can once again use non-open access content in SpringerLinks, after the Foundation [[phab:T368865|contacted]] them to restore access. You can read more about [[m:Tech/News/Recently_resolved_community_tasks|this and 21 other community-submitted tasks that were completed last week]]. 

'''Changes later this week'''
* This week, [[mw:Special:MyLanguage/Reading/Web/Accessibility for reading/Updates/2024-07 deployments|dark mode will be available on a number of Wikipedias]], both desktop and mobile, for logged-in and logged-out users. Interface admins and user script maintainers are encouraged to check gadgets and user scripts in the dark mode, to find any hard-coded colors and fix them. There are some [[mw:Special:MyLanguage/Recommendations for night mode compatibility on Wikimedia wikis|recommendations for dark mode compatibility]] to help.

'''Future changes'''
* [[File:Octicons-tools.svg|12px|link=|class=skin-invert|Advanced item]] Next week, functionaries, volunteers maintaining tools, and software development teams are invited to test the [[mw:Special:MyLanguage/Trust and Safety Product/Temporary Accounts|temporary accounts]] feature on testwiki. Temporary accounts is a feature that will help improve privacy on the wikis. No further temporary account deployments are scheduled yet. Please [[mw:Talk:Trust and Safety Product/Temporary Accounts|share your opinions and questions on the project talk page]]. [https://phabricator.wikimedia.org/T348895]
* Editors who upload files cross-wiki, or teach other people how to do so, may wish to join a Wikimedia Commons discussion. The Commons community is discussing limiting who can upload files through the cross-wiki upload/Upload dialog feature to users auto-confirmed on Wikimedia Commons. This is due to the large amount of copyright violations uploaded this way. There is a short summary at [[c:Special:MyLanguage/Commons:Cross-wiki upload|Commons:Cross-wiki upload]] and [[c:Commons:Village pump/Proposals#Deactivate cross-wiki uploads for new users|discussion at Commons:Village Pump]].

&lt;section begin=&quot;technews-2024-W30&quot;/&gt;&lt;div class=&quot;plainlinks&quot;&gt;
Latest '''[[m:Special:MyLanguage/Tech/News|tech news]]''' from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. [[m:Special:MyLanguage/Tech/News/2024/30|Translations]] are available.

'''Feature News'''
* Stewards can now [[:m:Special:MyLanguage/Global_blocks|globally block]] accounts. Before [[phab:T17294|the change]] only IP addresses and IP ranges could be blocked globally. Global account blocks are useful when the blocked user should not be logged out. [[:m:Special:MyLanguage/Global_locks|Global locks]] (a similar tool logging the user out of their account) are unaffected by this change. The new global account block feature is related to the [[mw:Special:MyLanguage/Trust and Safety Product/Temporary Accounts|Temporary Accounts]] project, which is a new type of user account that replaces IP addresses of unregistered editors that are no longer made public.
* Later this week, Wikimedia site users will notice that the Interface of [[mw:Special:MyLanguage/Extension:FlaggedRevs|FlaggedRevs]] (also known as &quot;Pending Changes&quot;) is improved and consistent with the rest of the MediaWiki interface and [[mw:Special:MyLanguage/Codex|Wikimedia's design system]]. The FlaggedRevs interface experience on mobile and [[mw:Special:MyLanguage/Skin:MinervaNeue|Minerva skin]] was inconsistent before it was fixed and ported to [[mw:Special:MyLanguage/Codex|Codex]] by the WMF Growth team and some volunteers. [https://phabricator.wikimedia.org/T191156]
*  Wikimedia site users can now submit account vanishing requests via [[m:Special:GlobalVanishRequest|GlobalVanishRequest]]. This feature is used when a contributor wishes to stop editing forever. It helps you hide your past association and edit to protect your privacy. Once processed, the account will be locked and renamed. [https://phabricator.wikimedia.org/T367329]
* Have you tried monitoring and addressing vandalism in Wikipedia using your phone? [https://diff.wikimedia.org/2024/07/10/%d9%90addressing-vandalism-with-a-tap-the-journey-of-introducing-the-patrolling-feature-in-the-mobile-app/ A Diff blog post on Patrolling features in the Mobile App] highlights some of the new capabilities of the feature, including swiping through a feed of recent changes and a personal library of user talk messages for use when patrolling from your phone. 
* Wikimedia contributors and GLAM (galleries, libraries, archives, and museums) organisations can now learn and measure the impact Wikimedia Commons is having towards creating quality encyclopedic content using the [https://doc.wikimedia.org/generated-data-platform/aqs/analytics-api/reference/commons.html Commons Impact Metrics] analytics dashboard. The dashboard offers organizations analytics on things like monthly edits in a category, the most viewed files, and which Wikimedia articles are using Commons images. As a result of these new data dumps, GLAM organisation can more reliably measure their return on investment for programs bringing content into the digital Commons. [https://diff.wikimedia.org/2024/07/19/commons-impact-metrics-now-available-via-data-dumps-and-api/]

'''Project Updates'''
*  Come share your ideas for improving the wikis on the newly reopened [[m:Special:MyLanguage/Community Wishlist|Community Wishlist]]. The Community Wishlist is Wikimedia’s forum for volunteers to share ideas (called wishes) to improve how the wikis work. The new version of the wishlist is always open, works with both wikitext and Visual Editor, and allows wishes in any language.

* Have you ever wondered how Wikimedia software works across over 300 languages? This is 253 languages more than the Google Chrome interface, and it's no accident. The Language and Product Localization Team at the Wikimedia Foundation supports your work by adapting all the tools and interfaces in the MediaWiki software so that contributors in our movement who translate pages and strings can translate them and have the sites in all languages. Read more about the team and their upcoming work on [https://diff.wikimedia.org/2024/07/17/building-towards-a-robust-multilingual-knowledge-ecosystem-for-the-wikimedia-movement/ Diff]. 
* How can Wikimedia build innovative and experimental products while maintaining such heavily used websites? A recent [https://diff.wikimedia.org/2024/07/09/on-the-value-of-experimentation/ blog post] by WMF staff Johan Jönsson highlights the work of the [[m:Future Audiences#Objectives and Key Results|WMF Future Audience initiative]], where the goal is not to build polished products but test out new ideas, such as a [[m:Future_Audiences/Experiments: conversational/generative AI|ChatGPT plugin]] and [[m:Future_Audiences/Experiment:Add a Fact|Add a Fact]], to help take Wikimedia into the future.

'''Feature news'''
* Editors using the Visual Editor in languages that use non-Latin characters for numbers, such as Hindi, Manipuri and Eastern Arabic, may notice some changes in the formatting of reference numbers. This is a side effect of preparing a new sub-referencing feature, and will also allow fixing some general numbering issues in Visual Editor. If you notice any related problems on your wiki, please share details at the [[m:Talk:WMDE Technical Wishes/Sub-referencing|project talkpage]].

'''Bugs status'''
* Some logged-in editors were briefly unable to edit or load pages last week. [[phab:T370304|These errors]] were mainly due to the addition of new [[mw:Special:MyLanguage/Help:Extension:Linter|linter]] rules which led to caching problems. Fixes have been applied and investigations are continuing.
* Editors can use the [[mw:Special:MyLanguage/Trust and Safety Product/IP Info|IP Information tool]] to get information about IP addresses. This tool is available as a Beta Feature in your preferences. The tool was not available for a few days last week, but is now working again. Thank you to Shizhao for filing the bug report. You can read about that, and [[m:Tech/News/Recently resolved community tasks#2024-07-25|28 other community-submitted tasks]] that were resolved last week.

'''Project updates'''
* There are new features and improvements to Phabricator from the Release Engineering and Collaboration Services teams, and some volunteers, including: the search systems, the new task creation system, the login systems, the translation setup which has resulted in support for more languages (thanks to Pppery), and fixes for many edge-case errors. You can [[phab:phame/post/view/316/iterative_improvements/|read details about these and other improvements in this summary]].
* There is an [[mw:Special:MyLanguage/Extension:Chart/Project/Updates|update on the Charts project]]. The team has decided which visualization library to use, which chart types to start focusing on, and where to store chart definitions.
* One new wiki has been created: a {{int:project-localized-name-group-wikivoyage}} in [[d:Q9056|Czech]] ([[voy:cs:|&lt;code&gt;voy:cs:&lt;/code&gt;]]) [https://phabricator.wikimedia.org/T370905]

* [[File:Octicons-tools.svg|12px|link=|class=skin-invert|Advanced item]] Two new parser functions will be available this week: &lt;code&gt;&lt;nowiki&gt;{{&lt;/nowiki&gt;[[mw:Special:MyLanguage/Help:Magic_words#dir|#dir]]&lt;nowiki&gt;}}&lt;/nowiki&gt;&lt;/code&gt; and &lt;code&gt;&lt;nowiki&gt;{{&lt;/nowiki&gt;[[mw:Special:MyLanguage/Help:Magic_words#bcp47|#bcp47]]&lt;nowiki&gt;}}&lt;/nowiki&gt;&lt;/code&gt;. These will reduce the need for &lt;code&gt;Template:Dir&lt;/code&gt; and &lt;code&gt;Template:BCP47&lt;/code&gt; on Commons and allow us to [[phab:T343131|drop 100 million rows]] from the &quot;what links here&quot; database. Editors at any wiki that use these templates, can help by replacing the templates with these new functions. The templates at Commons will be updated during the Hackathon at Wikimania. [https://phabricator.wikimedia.org/T359761][https://phabricator.wikimedia.org/T366623]
* Communities can request the activation of the visual editor on entire namespaces where discussions sometimes happen (for instance ''Wikipedia:'' or ''Wikisource:'' namespaces) if they understand the [[mw:Special:MyLanguage/Help:VisualEditor/FAQ#WPNS|known limitations]]. For discussions, users can already use [[mw:Special:MyLanguage/Help:DiscussionTools|DiscussionTools]] in these namespaces.
* The tracking category &quot;Pages using Timeline&quot; has been renamed to &quot;Pages using the EasyTimeline extension&quot; [https://translatewiki.net/wiki/Special:Translations?message=MediaWiki%3ATimeline-tracking-category&amp;namespace=8 in TranslateWiki]. Wikis that have created the category locally should rename their local creation to match.

'''Project updates'''
* Editors who help to organize WikiProjects and similar on-wiki collaborations, are invited to share ideas and examples of successful collaborations with the Campaigns and Programs teams. You can fill out [[m:Special:MyLanguage/Campaigns/WikiProjects|a brief survey]] or share your thoughts [[m:Talk:Campaigns/WikiProjects|on the talkpage]]. The teams are particularly looking for details about successful collaborations on non-English wikis.
* [[File:Octicons-tools.svg|12px|link=|class=skin-invert|Advanced item]] The new parser is being rolled out on {{int:project-localized-name-group-wikivoyage}} wikis over the next few months. The {{int:project-localized-name-enwikivoyage}} and {{int:project-localized-name-hewikivoyage}} were [[phab:T365367|switched]] to Parsoid last week.

'''Bugs status'''
* [[File:Octicons-tools.svg|12px|link=|class=skin-invert|Advanced item]] Your help is needed to check if any pages need to be moved or deleted. A maintenance script was run to clean up unreachable pages (due to Unicode issues or introduction of new namespaces/namespace aliases). The script tried to find appropriate names for the pages (e.g. by following the Unicode changes or by moving pages whose titles on Wikipedia start with &lt;code&gt;Talk:WP:&lt;/code&gt; so that their titles start with &lt;code&gt;Wikipedia talk:&lt;/code&gt;), but it may have failed for some pages, and moved them to &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;[[Special:PrefixIndex/T195546/]]&lt;/bdi&gt; instead. Your community should check if any pages are listed there, and move them to the correct titles, or delete them if they are no longer needed. A full log (including pages for which appropriate names could be found) is available in [[phab:P67388]].
* Editors who volunteer as [[mw:Special:MyLanguage/Help:Growth/Mentorship|mentors]] to newcomers on their wiki are once again able to access lists of potential mentees who they can connect with to offer help and guidance. This functionality was restored thanks to [[phab:T372164|a bug fix]]. Thank you to Mbch331 for filing the bug report. You can read about that, and 18 other community-submitted tasks that were [[m:Tech/News/Recently resolved community tasks|resolved last week]].

'''Feature news'''
* [[File:Octicons-tools.svg|12px|link=|class=skin-invert|Advanced item]] Administrators can now test the [[mw:Special:MyLanguage/Trust and Safety Product/Temporary Accounts|temporary accounts]] feature on test2wiki. This was done to allow cross-wiki testing of temporary accounts, for when temporary accounts switch between projects. The feature was enabled on testwiki a few weeks ago. No further temporary account deployments are scheduled yet. Temporary Accounts is a project to create a new type of user account that replaces IP addresses of unregistered editors which are no longer made public. Please [[mw:Talk:Trust and Safety Product/Temporary Accounts|share your opinions and questions on the project talk page]].
* Later this week, editors at wikis that use [[mw:Special:MyLanguage/Extension:FlaggedRevs|FlaggedRevs]] (also known as &quot;Pending Changes&quot;) may notice that the indicators at the top of articles have changed. This change makes the system more consistent with the rest of the MediaWiki interface. [https://phabricator.wikimedia.org/T191156]

'''Bugs status'''
* Editors who use the 2010 wikitext editor, and use the Character Insert buttons, will [[phab:T361465|no longer]] experience problems with the buttons adding content into the edit-summary instead of the edit-window. You can read more about that, and 26 other community-submitted tasks that were [[m:Tech/News/Recently resolved community tasks|resolved last week]].

'''Project updates'''
* [[File:Octicons-gift.svg|12px|link=|class=skin-invert|Wishlist item]] Please review and vote on [[m:Special:MyLanguage/Community Wishlist/Focus areas|Focus Areas]], which are groups of wishes that share a problem. Focus Areas were created for the newly reopened Community Wishlist, which is now open year-round for submissions. The first batch of focus areas are specific to moderator workflows, around welcoming newcomers, minimizing repetitive tasks, and prioritizing tasks. Once volunteers have reviewed and voted on focus areas, the Foundation will then review and select focus areas for prioritization.
* Do you have a project and are willing to provide a three (3) month mentorship for an intern? [[mw:Special:MyLanguage/Outreachy|Outreachy]] is a twice a year program for people to participate in a paid internship that will start in December 2024 and end in early March 2025, and they need mentors and projects to work on. Projects can be focused on coding or non-coding (design, documentation, translation, research). See the Outreachy page for more details, and a list of past projects since 2013.

'''Weekly highlight'''
* Editors and volunteer developers interested in data visualisation can now test the new software for charts. Its early version is available on beta Commons and beta Wikipedia. This is an important milestone before making charts available on regular wikis. You can [[mw:Special:MyLanguage/Extension:Chart/Project/Updates|read more about this project update]] and help to test the charts.

'''Feature news'''
* Editors who use the [[{{#special:Unusedtemplates}}]] page can now filter out pages which are expected to be there permanently, such as sandboxes, test-cases, and templates that are always substituted. Editors can add the new magic word [[mw:Special:MyLanguage/Help:Magic words#EXPECTUNUSEDTEMPLATE|&lt;code dir=&quot;ltr&quot;&gt;&lt;nowiki&gt;__EXPECTUNUSEDTEMPLATE__&lt;/nowiki&gt;&lt;/code&gt;]] to a template page to hide it from the listing. Thanks to Sophivorus and DannyS712 for these improvements. [https://phabricator.wikimedia.org/T184633]
* Editors who use the New Topic tool on discussion pages, will [[phab:T334163|now be reminded]] to add a section header, which should help reduce the quantity of newcomers who add sections without a header. You can read more about that, and {{formatnum:28}} other community-submitted tasks that were [[m:Tech/News/Recently resolved community tasks|resolved last week]].
* Last week, some Toolforge tools had occasional connection problems. The cause is still being investigated, but the problems have been resolved for now. [https://phabricator.wikimedia.org/T373243]
* Translation administrators at multilingual wikis, when editing multiple translation units, can now easily mark which changes require updates to the translation. This is possible with the [[phab:T298852#10087288|new dropdown menu]].

'''Project updates'''
* A new draft text of a policy discussing the use of Wikimedia's APIs [[m:Special:MyLanguage/API Policy Update 2024|has been published on Meta-Wiki]]. The draft text does not reflect a change in policy around the APIs; instead, it is an attempt to codify existing API rules. Comments, questions, and suggestions are welcome on [[m:Talk:API Policy Update 2024|the proposed update’s talk page]] until September 13 or until those discussions have concluded.

* Starting this week, the standard [[mw:Special:MyLanguage/Extension:CodeMirror|syntax highlighter]] will receive new colors that make them compatible in dark mode. This is the first of many changes to come as part of a major upgrade to syntax highlighting. You can learn more about what's to come on the [[mw:Special:MyLanguage/Help:Extension:CodeMirror|help page]]. [https://phabricator.wikimedia.org/T365311][https://phabricator.wikimedia.org/T259059]
* Editors of wikis using Wikidata will now be notified of only relevant Wikidata changes in their watchlist. This is because the Lua functions &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;entity:getSitelink()&lt;/code&gt;&lt;/bdi&gt; and &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;mw.wikibase.getSitelink(qid)&lt;/code&gt;&lt;/bdi&gt; will have their logic unified for tracking different aspects of sitelinks to reduce junk notifications from [[m:Wikidata For Wikimedia Projects/Projects/Watchlist Wikidata Sitelinks Tracking|inconsistent sitelinks tracking]].

'''Project updates'''
*  Users of all Wikis will have access to Wikimedia sites as read-only for a few minutes on September 25, starting at 15:00 UTC. This is a planned datacenter switchover for maintenance purposes. More information will be published in Tech News and will also be posted on individual wikis in the coming weeks. [https://phabricator.wikimedia.org/T370962]
* Contributors of [[phab:T363538#10123348|11 Wikipedias]], including English will have a new &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;MOS&lt;/code&gt;&lt;/bdi&gt; namespace added to their Wikipedias. This improvement ensures that links beginning with &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;MOS:&lt;/code&gt;&lt;/bdi&gt; (usually shortcuts to the [[w:en:Wikipedia:Manual of Style|Manual of Style]]) are not broken by [[w:en:Mooré|Mooré]] Wikipedia (language code &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;mos&lt;/code&gt;&lt;/bdi&gt;).

'''Improvements and Maintenance'''
* [[File:Octicons-gift.svg|12px|link=|class=skin-invert|Wishlist item]] Editors interested in templates can help by reading the latest Wishlist focus area, [[m:Special:MyLanguage/Community Wishlist/Focus areas/Template recall and discovery|Template recall and discovery]], and share your feedback on the talkpage. This input helps the Community Tech team to decide the right technical approach to build. Everyone is also encouraged to continue adding [[m:Special:MyLanguage/Community Wishlist|new wishes]].
* The new automated [[{{#special:NamespaceInfo}}]] page helps editors understand which [[mw:Special:MyLanguage/Help:Namespaces|namespaces]] exist on each wiki, and some details about how they are configured. Thanks to DannyS712 for these improvements. [https://phabricator.wikimedia.org/T263513]
* [[mw:Special:MyLanguage/Help:Edit check#Reference check|References Check]] is a feature that encourages editors to add a citation when they add a new paragraph to a Wikipedia article. For a short time, the corresponding tag &quot;Edit Check (references) activated&quot; was erroneously being applied to some edits outside of the main namespace. This has been fixed. [https://phabricator.wikimedia.org/T373692]
* It is now possible for a wiki community to change the order in which a page’s categories are displayed on their wiki. By default, categories are displayed in the order they appear in the wikitext. Now, wikis with a consensus to do so can [[m:Special:MyLanguage/Requesting wiki configuration changes|request]] a configuration change to display them in alphabetical order. [https://phabricator.wikimedia.org/T373480]
* [[File:Octicons-tools.svg|12px|link=|class=skin-invert|Advanced item]] Tool authors can now access ToolsDB's [[wikitech:Portal:Data Services#ToolsDB|public databases]] from both [[m:Special:MyLanguage/Research:Quarry|Quarry]] and [[wikitech:Superset|Superset]]. Those databases have always been accessible to every [[wikitech:Portal:Toolforge|Toolforge]] user, but they are now more broadly accessible, as Quarry can be accessed by anyone with a Wikimedia account. In addition, Quarry's internal database can now be [[m:Special:MyLanguage/Research:Quarry#Querying Quarry's own database|queried from Quarry itself]]. This database contains information about all queries that are being run and starred by users in Quarry. This information was already public through the web interface, but you can now query it using SQL. You can read more about that, and {{formatnum:20}} other community-submitted tasks that were [[m:Tech/News/Recently resolved community tasks|resolved last week]].
* Any pages or tools that still use the very old CSS classes &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;mw-message-box&lt;/code&gt;&lt;/bdi&gt; need to be updated. These old classes will be removed next week or soon afterwards. Editors can use a [https://global-search.toolforge.org/?q=mw-message-box&amp;regex=1&amp;namespaces=&amp;title= global-search] to determine what needs to be changed. It is possible to use the newer &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;cdx-message&lt;/code&gt;&lt;/bdi&gt; group of classes as a replacement (see [https://doc.wikimedia.org/codex/latest/components/demos/message.html#css-only-version the relevant Codex documentation], and [https://meta.wikimedia.org/w/index.php?title=Tech/Header&amp;diff=prev&amp;oldid=27449042 an example update]), but using locally defined onwiki classes would be best. [https://phabricator.wikimedia.org/T374499]

'''Technical project updates'''
* Next week, all Wikimedia wikis will be read-only for a few minutes. This will start on September 25 at [https://zonestamp.toolforge.org/1727276400 15:00 UTC]. This is a planned datacenter switchover for maintenance purposes. [[m:Special:MyLanguage/Tech/Server switch|This maintenance process also targets other services.]] The previous switchover took 3 minutes, and the Site Reliability Engineering teams use many tools to make sure that this essential maintenance work happens as quickly as possible.

* All wikis will be [[m:Special:MyLanguage/Tech/Server switch|read-only]] for a few minutes on Wednesday September 25 at [https://zonestamp.toolforge.org/1727276400 15:00 UTC]. Reading the wikis will not be interrupted, but editing will be paused. These twice-yearly processes allow WMF's site reliability engineering teams to remain prepared to keep the wikis functioning even in the event of a major interruption to one of our data centers.

'''Updates for editors'''
[[File:Add alt text from a halfsheet, with the article behind.png|thumb|A screenshot of the interface for the Alt Text suggested-edit feature]]
* Editors who use the iOS Wikipedia app in Spanish, Portuguese, French, or Chinese, may see the [[mw:Special:MyLanguage/Wikimedia Apps/iOS Suggested edits project/Alt Text Experiment|Alt Text suggested-edit experiment]] after editing an article, or completing a suggested edit using &quot;[[mw:Special:MyLanguage/Wikimedia Apps/iOS Suggested edits project#Hypothesis 2 Add an Image Suggested Edit|Add an image]]&quot;. Alt-text helps people with visual impairments to read Wikipedia articles. The team aims to learn if adding alt-text to images is a task that editors can be successful with. Please share any feedback on [[mw:Talk:Wikimedia Apps/iOS Suggested edits project/Alt Text Experiment|the discussion page]].
* The Codex color palette has been updated with new and revised colors for the MediaWiki user interfaces. The [[mw:Special:MyLanguage/Design System Team/Color/Design documentation#Updates|most noticeable changes]] for editors include updates for: dark mode colors for Links and for quiet Buttons (progressive and destructive), visited Link colors for both light and dark modes, and background colors for system-messages in both light and dark modes.
* [[File:Octicons-tools.svg|12px|link=|class=skin-invert|Advanced item]] It is now possible to include clickable wikilinks and external links inside code blocks. This includes links that are used within &lt;code&gt;&lt;nowiki&gt;&lt;syntaxhighlight&gt;&lt;/nowiki&gt;&lt;/code&gt; tags and on code pages (JavaScript, CSS, Scribunto and Sanitized CSS). Uses of template syntax &lt;code&gt;&lt;nowiki&gt;{{…}}&lt;/nowiki&gt;&lt;/code&gt; are also linked to the template page. Thanks to SD0001 for these improvements. [https://phabricator.wikimedia.org/T368166]

'''Updates for technical contributors'''
* [[File:Octicons-tools.svg|12px|link=|class=skin-invert|Advanced item]] From [[m:Special:MyLanguage/Wikimedia Enterprise|Wikimedia Enterprise]]: 
** The API now enables 5,000 on-demand API requests per month and twice-monthly HTML snapshots freely (gratis and libre). More information on the updates and also improvements to the software development kits (SDK) are explained on [https://enterprise.wikimedia.com/blog/enhanced-free-api/ the project's blog post]. While Wikimedia Enterprise APIs are designed for high-volume commercial reusers, this change enables many more community use-cases to be built on the service too.
** The Snapshot API (html dumps) have added beta Structured Contents endpoints ([https://enterprise.wikimedia.com/blog/structured-contents-snapshot-api/ blog post on that]) as well as released two beta datasets (English and French Wikipedia) from that endpoint to Hugging Face for public use and feedback ([https://enterprise.wikimedia.com/blog/hugging-face-dataset/ blog post on that]). These pre-parsed data sets enable new options for researchers, developers, and data scientists to use and study the content.

'''In depth'''
* [[File:Octicons-tools.svg|12px|link=|class=skin-invert|Advanced item]] The Wikidata Query Service (WDQS) is used to get answers to questions using the Wikidata data set. As Wikidata grows, we had to make a major architectural change so that WDQS could remain performant. As part of the [[d:Special:MyLanguage/Wikidata:SPARQL query service/WDQS graph split|WDQS Graph Split project]], we have new SPARQL endpoints available for serving the &quot;[https://query-scholarly.wikidata.org scholarly]&quot; and &quot;[https://query-main.wikidata.org main]&quot; subgraphs of Wikidata. The [http://query.wikidata.org query.wikidata.org endpoint] will continue to serve the full Wikidata graph until March 2025. After this date, it will only serve the main graph. For more information, please see [[d:Special:MyLanguage/Wikidata:SPARQL query service/WDQS backend update/September 2024 scaling update|the announcement on Wikidata]].

&lt;section begin=&quot;technews-2024-W40&quot;/&gt;&lt;div class=&quot;plainlinks&quot;&gt;
Latest '''[[m:Special:MyLanguage/Tech/News|tech news]]''' from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. [[m:Special:MyLanguage/Tech/News/2024/40|Translations]] are available.

'''Updates for editors'''
* Readers of [[phab:T375401|42 more wikis]] can now use Dark Mode. If the option is not yet available for logged-out users of your wiki, this is likely because many templates do not yet display well in Dark Mode. Please use the [https://night-mode-checker.wmcloud.org/ night-mode-checker tool] if you are interested in helping to reduce the number of issues. The [[mw:Special:MyLanguage/Recommendations for night mode compatibility on Wikimedia wikis|recommendations page]] provides guidance on this. Dark Mode is enabled on additional wikis once per month.
* Editors using the 2010 wikitext editor as their default can access features from the 2017 wikitext editor by adding &lt;code dir=ltr&gt;?veaction=editsource&lt;/code&gt; to the URL. If you would like to enable the 2017 wikitext editor as your default, it can be set in [[Special:Preferences#mw-input-wpvisualeditor-newwikitext|your preferences]]. [https://phabricator.wikimedia.org/T239796]
* For logged-out readers using the Vector 2022 skin, the &quot;donate&quot; link has been moved from a collapsible menu next to the content area into a more prominent top menu, next to &quot;Create an account&quot;. This restores the link to the level of prominence it had in the Vector 2010 skin. [[mw:Readers/2024 Reader and Donor Experiences#Donor Experiences (Key Result WE 3.2 and the related hypotheses)|Learn more]] about the changes related to donor experiences. [https://phabricator.wikimedia.org/T373585]
* The CampaignEvents extension provides tools for organizers to more easily manage events, communicate with participants, and promote their events on the wikis. The extension has been [[m:Special:MyLanguage/CampaignEvents/Deployment status|enabled]] on Arabic Wikipedia, Igbo Wikipedia, Swahili Wikipedia, and Meta-Wiki. [[w:zh:Wikipedia:互助客栈/其他#引進CampaignEvents擴充功能|Chinese Wikipedia has decided]] to enable the extension, and discussions on the extension are in progress [[w:es:Wikipedia:Votaciones/2024/Sobre la política de Organizadores de Eventos|on Spanish Wikipedia]] and [[d:Wikidata:Project chat#Enabling the CampaignEvents Extention on Wikidata|on Wikidata]]. To learn how to enable the extension on your wiki, you can visit [[m:Special:MyLanguage/CampaignEvents|the CampaignEvents page on Meta-Wiki]].
* View all {{formatnum:22}} community-submitted {{PLURAL:22|task|tasks}} that were [[m:Tech/News/Recently resolved community tasks|resolved last week]].

'''Updates for technical contributors'''
* Developers with an account on Wikitech-wiki should [[wikitech:Wikitech/SUL-migration|check if any action is required]] for their accounts. The wiki is being changed to use the single-user-login (SUL) system, and other configuration changes. This change will help reduce the overall complexity for the weekly software updates across all our wikis.

'''In depth'''
* The [[m:Special:MyLanguage/Tech/Server switch|server switch]] was completed successfully last week with a read-only time of [[wikitech:Switch Datacenter#Past Switches|only 2 minutes 46 seconds]]. This periodic process makes sure that engineers can switch data centers and keep all of the wikis available for readers, even if there are major technical issues. It also gives engineers a chance to do maintenance and upgrades on systems that normally run 24 hours a day, and often helps to reveal weaknesses in the infrastructure. The process involves dozens of software services and hundreds of hardware servers, and requires multiple teams working together. Work over the past few years has reduced the time from 17 minutes down to 2–3 minutes.

'''Meetings and events'''
* October 4–6: [[m:Special:MyLanguage/WikiIndaba conference 2024|WikiIndaba Conference's Hackathon]] in Johannesburg, South Africa
* November 4–6: [[mw:Special:MyLanguage/MediaWiki Users and Developers Conference Fall 2024|MediaWiki Users and Developers Conference Fall 2024]] in Vienna, Austria

Thanks to SD0001 for these improvements. [https://phabricator.wikimedia.org/T40932]
* Customized copyright footer messages on all wikis will be updated. The new versions will use wikitext markup instead of requiring editing raw HTML. [https://phabricator.wikimedia.org/T375789]
* [[File:Octicons-tools.svg|12px|link=|class=skin-invert|Advanced item]] Later this month, [[mw:Special:MyLanguage/Trust and Safety Product/Temporary Accounts|temporary accounts]] will be rolled out on several pilot wikis. The final list of the wikis will be published in the second half of the month. If you maintain any tools, bots, or gadgets on [[phab:T376499|these 11 wikis]], and your software is using data about IP addresses or is available for logged-out users, please check if it needs to be updated to work with temporary accounts. [[mw:Special:MyLanguage/Trust and Safety Product/Temporary Accounts/For developers|Guidance on how to update the code is available]].
* [[File:Octicons-tools.svg|12px|link=|class=skin-invert|Advanced item]] Rate limiting has been enabled for the code review tools [[Wikitech:Gerrit|Gerrit]] and [[Wikitech:GitLab|GitLab]] to address ongoing issues caused by malicious traffic and scraping.

'''Updates for editors'''
* The Structured Discussion extension (also known as Flow) is starting to be removed. This extension is unmaintained and causes issues. It will be replaced by [[mw:Special:MyLanguage/Help:DiscussionTools|DiscussionTools]], which is used on any regular talk page. [[mw:Special:MyLanguage/Structured Discussions/Deprecation#Deprecation timeline|A first set of wikis]] are being contacted. These wikis are invited to stop using Flow, and to move all Flow boards to sub-pages, as archives. At these wikis, a script will move all Flow pages that aren't a sub-page to a sub-page automatically, starting on 22 October 2024. On 28 October 2024, all Flow boards at these wikis will be set in read-only mode. [https://www.mediawiki.org/wiki/Structured_Discussions/Deprecation][https://phabricator.wikimedia.org/T370722]
* WMF's Search Platform team is working on making it easier for readers to perform text searches in their language. A [[phab:T332342|change last week]] on over 30 languages makes it easier to find words with accents and other diacritics. This applies to both full-text search and to types of advanced search such as the &lt;bdi lang=&quot;en&quot; dir=&quot;ltr&quot;&gt;''hastemplate''&lt;/bdi&gt; and &lt;bdi lang=&quot;en&quot; dir=&quot;ltr&quot;&gt;''incategory''&lt;/bdi&gt; keywords. More technical details (including a few other minor search upgrades) are available.

'''Updates for technical contributors'''
* Editors who use the Toolforge tool [[toolforge:copyvios|Earwig's Copyright Violation Detector]] will now be required to log in with their Wikimedia account before running checks using the &quot;search engine&quot; option. This change is needed to help prevent external bots from misusing the system. Thanks to Chlod for these improvements. [https://en.wikipedia.org/wiki/Wikipedia_talk:New_pages_patrol/Reviewers#Authentication_is_now_required_for_search_engine_checks_on_Earwig's_Copyvio_Tool]
* [[m:Special:MyLanguage/Phabricator|Phabricator]] users can create tickets and add comments on existing tickets via Email again. [[mw:Special:MyLanguage/Phabricator/Help#Using email|Sending email to Phabricator]] has been fixed. [https://phabricator.wikimedia.org/T356077]
* [[File:Octicons-tools.svg|12px|link=|class=skin-invert|Advanced item]] Some HTML elements in the interface are now wrapped with a &lt;code&gt;&lt;nowiki&gt;&lt;bdi&gt;&lt;/nowiki&gt;&lt;/code&gt; element, to make our HTML output more aligned with Web standards. More changes like this will be coming in future weeks. This change might break some tools that rely on the previous HTML structure of the interface. Note that relying on the HTML structure of the interface is [[mw:Special:MyLanguage/Stable interface policy/Frontend#What is not stable?|not recommended]] and might break at any time.

'''Weekly highlight'''
* The Mobile Apps team has released an [[mw:Special:MyLanguage/Wikimedia Apps/Team/iOS/Navigation Refresh#Phase 1: Creating a user Profile Menu (T373714)|update]] to the iOS app's navigation, and it is now available in the latest App store version. The team added a new Profile menu that allows for easy access to editor features like Notifications and Watchlist from the Article view, and brings the &quot;Donate&quot; button into a more accessible place for users who are reading an article. This is the first phase of a larger planned [[mw:Special:MyLanguage/Wikimedia Apps/Team/iOS/Navigation Refresh|navigation refresh]] to help the iOS app transition from a primarily reader-focused app, to an app that fully supports reading and editing. The Wikimedia Foundation has added more editing features and support for on-wiki communication based on volunteer requests in recent years.
[[File:IOS App Navigation refresh first phase 05.png|thumb|iOS Wikipedia App's profile menu and contents]]

'''Updates for editors'''
* Wikipedia readers can now download a browser extension to experiment with some early ideas on potential features that recommend articles for further reading, automatically summarize articles, and improve search functionality. For more details and to stay updated, check out the Web team's [[mw:Special:MyLanguage/Reading/Web/Content Discovery Experiments|Content Discovery Experiments page]] and [[mw:Special:MyLanguage/Newsletter:Web team's projects|subscribe to their newsletter]].
* Later this month, logged-out editors of [[phab:T376499|these 12 wikis]] will start to have [[mw:Special:Mylanguage/Trust and Safety Product/Temporary Accounts|temporary accounts]] created. The list may slightly change - some wikis may be removed but none will be added. Temporary account is a new [[mw:Special:MyLanguage/User account types|type of user account]]. It enhances the logged-out editors' privacy and makes it easier for community members to communicate with them. If you maintain any tools, bots, or gadgets on these 12 wikis, and your software is using data about IP addresses or is available for logged-out users, please check if it needs to be updated to work with temporary accounts. [[mw:Special:MyLanguage/Trust and Safety Product/Temporary Accounts/For developers|Guidance on how to update the code is available]].

* It is now possible to create functions on Wikifunctions using Wikidata lexemes, through the new [[f:Z6005|Wikidata lexeme type]] launched last week. When you go to one of these functions, the user interface provides a lexeme selector that helps you pick a lexeme from Wikidata that matches the word you type. After hitting run, your selected lexeme is retrieved from Wikidata, transformed into a Wikidata lexeme type, and passed into the selected function. Read more about this in [[f:Special:MyLanguage/Wikifunctions:Status updates/2024-10-17#Function of the Week: select representation from lexeme|the latest Wikifunctions newsletter]].

'''Updates for technical contributors'''
* [[File:Octicons-tools.svg|12px|link=|class=skin-invert|Advanced item]] Users of the Wikimedia sites can now format dates more easily in different languages with the new &lt;code dir=&quot;ltr&quot;&gt;{{[[mw:Special:MyLanguage/Help:Extension:ParserFunctions##timef|#timef]]:…}}&lt;/code&gt; parser function. For example, &lt;code dir=&quot;ltr&quot;&gt;&lt;nowiki&gt;{{#timef:now|date|en}}&lt;/nowiki&gt;&lt;/code&gt; will show as &quot;&lt;bdi lang=&quot;en&quot; dir=&quot;ltr&quot;&gt;{{#timef:now|date|en}}&lt;/bdi&gt;&quot;. Previously, &lt;code dir=&quot;ltr&quot;&gt;&lt;nowiki&gt;{{#time:…}}&lt;/nowiki&gt;&lt;/code&gt; could be used to format dates, but this required knowledge of the order of the time and date components and their intervening punctuation. &lt;code dir=&quot;ltr&quot;&gt;#timef&lt;/code&gt; (or &lt;code dir=&quot;ltr&quot;&gt;#timefl&lt;/code&gt; for local time) provides access to the standard date formats that MediaWiki uses in its user interface. This may help to simplify some templates on multi-lingual wikis like Commons and Meta.

The Guided Tours extension now works with [[mw:Special:MyLanguage/Manual:Dark mode|dark mode]]. Guided Tour maintainers can check their tours to see that nothing looks odd. They can also set &lt;code&gt;emitTransitionOnStep&lt;/code&gt; to &lt;code&gt;true&lt;/code&gt; to fix an old bug. They can use the new flag &lt;code&gt;allowAutomaticBack&lt;/code&gt; to avoid back-buttons they don't want. [https://phabricator.wikimedia.org/T73927#10241528]

* Stewards can now make [[m:Special:MyLanguage/Global blocks|global account blocks]] cause global [[mw:Special:MyLanguage/Autoblock|autoblocks]]. This will assist stewards in preventing abuse from users who have been globally blocked. This includes preventing globally blocked temporary accounts from exiting their session or switching browsers to make subsequent edits for 24 hours. Previously, temporary accounts could exit their current session or switch browsers to continue editing. This is an anti-abuse tool improvement for the [[mw:Special:MyLanguage/Trust and Safety Product/Temporary Accounts|Temporary Accounts]] project. You can read more about the [[mw:Special:MyLanguage/Trust and Safety Product/Temporary Accounts/Updates|progress on key features for temporary accounts]]. [https://phabricator.wikimedia.org/T368949]

'''Updates for editors'''
* Two new parser functions were added this week. The &lt;code dir=&quot;ltr&quot;&gt;&lt;nowiki&gt;{{&lt;/nowiki&gt;[[mw:Special:MyLanguage/Help:Magic words#interwikilink|#interwikilink]]&lt;nowiki&gt;}}&lt;/nowiki&gt;&lt;/code&gt; function adds an [[mw:Special:MyLanguage/Help:Links#Interwiki links|interwiki link]] and the &lt;code dir=&quot;ltr&quot;&gt;&lt;nowiki&gt;{{&lt;/nowiki&gt;[[mw:Special:MyLanguage/Help:Magic words#interlanguagelink|#interlanguagelink]]&lt;nowiki&gt;}}&lt;/nowiki&gt;&lt;/code&gt; function adds an [[mw:Special:MyLanguage/Help:Links#Interlanguage links|interlanguage link]]. These parser functions are useful on wikis where namespaces conflict with interwiki prefixes. For example, links beginning with &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;MOS:&lt;/code&gt;&lt;/bdi&gt; on English Wikipedia [[phab:T363538|conflict with the &lt;code&gt;mos&lt;/code&gt; language code prefix of Mooré Wikipedia]].
* Starting this week, Wikimedia wikis no longer support connections using old RSA-based HTTPS certificates, specifically rsa-2048. This change is to improve security for all users. Some older, unsupported browser or smartphone devices will be unable to connect; Instead, they will display a connectivity error. See the [[wikitech:HTTPS/Browser_Recommendations|HTTPS Browser Recommendations page]] for more-detailed information.

'''Updates for technical contributors'''
* In late February, temporary accounts will be rolled out on at least 10 large wikis. This deployment will have a significant effect on the community-maintained code. This is about Toolforge tools, bots, gadgets, and user scripts that use IP address data or that are available for logged-out users. The Trust and Safety Product team wants to identify this code, monitor it, and assist in updating it ahead of the deployment to minimize disruption to workflows. The team asks technical editors and volunteer developers to help identify such tools by adding them to [[mw:Trust and Safety Product/Temporary Accounts/For developers/Impacted tools|this list]]. In addition, review the [[mw:Special:MyLanguage/Trust and Safety Product/Temporary Accounts/For developers|updated documentation]] to learn how to adjust the tools.

* Technical documentation contributors can find updated resources, and new ways to connect with each other and the Wikimedia Technical Documentation Team, at the [[mw:Special:MyLanguage/Documentation|Documentation hub]] on MediaWiki.org. This page links to: resources for writing and improving documentation, a new &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;#wikimedia-techdocs&lt;/bdi&gt; IRC channel on libera.chat, a listing of past and upcoming documentation events, and ways to request a documentation consultation or review. If you have any feedback or ideas for improvements to the documentation ecosystem, please [[mw:Wikimedia Technical Documentation Team#Contact us|contact the Technical Documentation Team]].

'''Updates for editors'''
[[File:Edit Check on Desktop.png|thumb|Layout change for the Edit Check feature]]
* Later this week, [[mw:Special:MyLanguage/Edit check|Edit Check]] will be relocated to a sidebar on desktop. Edit check is the feature for new editors to help them follow policies and guidelines. This layout change creates space to present people with [[mw:Edit check#1 November 2024|new Checks]] that appear ''while'' they are typing. The [[mw:Special:MyLanguage/Edit check#Reference Check A/B Test|initial results]] show newcomers encountering Edit Check are 2.2 times more likely to publish a new content edit that includes a reference and is not reverted.
* The Chart extension, which enables editors to create data visualizations, was successfully made available on MediaWiki.org and three pilot wikis (Italian, Swedish, and Hebrew Wikipedias). You can see a working examples [[testwiki:Charts|on Testwiki]] and read [[mw:Special:MyLanguage/Extension:Chart/Project/Updates|the November project update]] for more details.
* Translators in wikis where the [[mw:Special:MyLanguage/Content translation/Section translation#Try the tool|mobile experience of Content Translation is available]], can now discover articles in Wikiproject campaigns of their interest from the &quot;[https://test.wikipedia.org/w/index.php?title=Special:ContentTranslation&amp;campaign=specialcx&amp;filter-type=automatic&amp;filter-id=collections&amp;active-list=suggestions&amp;from=es&amp;to=en All collection]&quot; category in the articles suggestion feature. Wikiproject Campaign organizers can use this feature, to help translators to discover articles of interest, by adding the &lt;code dir=ltr&gt;&lt;nowiki&gt;&lt;page-collection&gt; &lt;/page-collection&gt;&lt;/nowiki&gt;&lt;/code&gt; tag to their campaign article list page on Meta-wiki. This will make those articles discoverable in the Content Translation tool. For more detailed information on how to use the tool and tag, please refer to [[mw:Special:MyLanguage/Translation suggestions: Topic-based &amp; Community-defined lists/How to use the features|the step-by-step guide]]. [https://phabricator.wikimedia.org/T378958]
* The [[mw:Special:MyLanguage/Extension:Nuke|Nuke]] feature, which enables administrators to mass delete pages, now has a [[phab:T376379#10310998|multiselect filter for namespace selection]]. This enables users to select multiple specific namespaces, instead of only one or all, when fetching pages for deletion.
* The Nuke feature also now [[phab:T364225#10371365|provides links]] to the userpage of the user whose pages were deleted, and to the pages which were not selected for deletion, after page deletions are queued. This enables easier follow-up admin-actions. Thanks to Chlod and the Moderator Tools team for both of these improvements. [https://phabricator.wikimedia.org/T364225#10371365]
* The Editing Team is working on making it easier to populate citations from archive.org using the [[mw:Special:MyLanguage/Citoid/Enabling Citoid on your wiki|Citoid]] tool, the auto-filled citation generator. They are asking communities to add two parameters preemptively, &lt;code dir=ltr&gt;archiveUrl&lt;/code&gt; and &lt;code dir=ltr&gt;archiveDate&lt;/code&gt;, within the TemplateData for each citation template using Citoid. You can see an [https://en.wikipedia.org/w/index.php?title=Template%3ACite_web%2Fdoc&amp;diff=1261320172&amp;oldid=1260788022 example of a change in a template], and a [https://global-search.toolforge.org/?namespaces=10&amp;q=%5C%22citoid%5C%22%3A%20%5C%7B&amp;regex=1&amp;title= list of all relevant templates]. [https://phabricator.wikimedia.org/T374831]
* One new wiki has been created: a {{int:project-localized-name-group-wikivoyage}} in [[d:Q9240|Indonesian]] ([[voy:id:|&lt;code&gt;voy:id:&lt;/code&gt;]]) [https://phabricator.wikimedia.org/T380726]
* Last week, all wikis had problems serving pages to logged-in users and some logged-out users for 30–45 minutes. This was caused by a database problem, and investigation is ongoing. [https://www.wikimediastatus.net/incidents/3g2ckc7bp6l9]

For example, a bug in the [[mw:Special:MyLanguage/Help:Growth/Tools/Add a link|Add Link]] feature has been fixed. Previously, the list of sections which are excluded from Add Link was partially ignored in certain cases. [https://phabricator.wikimedia.org/T380455][https://phabricator.wikimedia.org/T380329]

'''Updates for technical contributors'''
* [[mw:Special:MyLanguage/Codex|Codex]], the design system for Wikimedia, now has an early-stage [[gitiles:design/codex-php|implementation in PHP]]. It is available for general use in MediaWiki extensions and Toolforge apps through [https://packagist.org/packages/wikimedia/codex Composer], with use in MediaWiki core coming soon. More information is available in [[wmdoc:design-codex-php/main/index.html|the documentation]]. Thanks to Doğu for the inspiration and many contributions to the library. [https://phabricator.wikimedia.org/T379662]
* [https://en.wikipedia.org/api/rest_v1/ Wikimedia REST API] users, such as bot operators and tool maintainers, may be affected by ongoing upgrades. On December 4, the MediaWiki Interfaces team began rerouting page/revision metadata and rendered HTML content endpoints on [[testwiki:|testwiki]] from RESTbase to comparable MediaWiki REST API endpoints. The team encourages active users of these endpoints to verify their tool's behavior on testwiki and raise any concerns on the related [[phab:T374683|Phabricator ticket]] before the end of the year, as they intend to roll out the same change across all Wikimedia projects in early January. These changes are part of the work to replace the outdated [[mw:RESTBase/deprecation|RESTBase]] system.
* The [https://wikimediafoundation.limesurvey.net/986172 2024 Developer Satisfaction Survey] is seeking the opinions of the Wikimedia developer community. Please take the survey if you have any role in developing software for the Wikimedia ecosystem. The survey is open until 3 January 2025, and has an associated [[foundation:Legal:Developer Satisfaction Survey 2024 Privacy Statement|privacy statement]].
* There is no new MediaWiki version this week. [https://wikitech.wikimedia.org/wiki/Deployments/Yearly_calendar]

'''Meetings and events'''
* The next meeting in the series of [[c:Commons:WMF support for Commons/Commons community calls|Wikimedia Foundation discussions with the Wikimedia Commons community]] will take place on [[m:Event:Commons community discussion - 12 December 2024 08:00 UTC|December 12 at 8:00 UTC]] and [[m:Event:Commons community discussion - 12_December 2024 16:00 UTC|at 16:00 UTC]].

The [[m:Special:MyLanguage/CampaignEvents|CampaignEvents extension]] offers organizers features like event registration management, event/wikiproject promotion, finding potential participants, and more - all directly on-wiki. If you are an organizer or think your community would benefit from this extension, start a discussion to enable it on your wiki today. To learn more about how to enable this extension on your wiki, visit the [[m:CampaignEvents/Deployment status#How to Request the CampaignEvents Extension for your wiki|deployment status page]].

'''Updates for editors'''
* Users of the iOS Wikipedia App in Italy and Mexico on the Italian, Spanish, and English Wikipedias, can see a [[mw:Special:MyLanguage/Wikimedia Apps/Team/iOS/Personalized Wikipedia Year in Review|personalized Year in Review]] with insights based on their reading and editing history.
* Users of the Android Wikipedia App in Sub-Saharan Africa and South Asia can see the new [[mw:Special:MyLanguage/Wikimedia Apps/Team/Android/Rabbit Holes|Rabbit Holes]] feature. This feature shows a suggested search term in the Search bar based on the current article being viewed, and a suggested reading list generated from the user’s last two visited articles.
* The [[m:Special:MyLanguage/Global reminder bot|global reminder bot]] is now active and running on nearly 800 wikis. This service reminds most users holding temporary rights when they are about to expire, so that they can renew should they want to. See [[m:Global reminder bot/Technical details|the technical details page]] for more information.
* The next issue of Tech News will be sent out on 13 January 2025 because of the end of year holidays. Thank you to all of the translators, and people who submitted content or feedback, this year.
* [[File:Octicons-sync.svg|12px|link=|class=skin-invert|Recurrent item]] View all {{formatnum:27}} community-submitted {{PLURAL:27|task|tasks}} that were [[m:Special:MyLanguage/Tech/News/Recently resolved community tasks|resolved last week]]. For example, a bug was [[phab:T374988|fixed]] in the Android Wikipedia App which had caused translatable SVG images to show the wrong language when they were tapped.

'''Weekly highlight'''
* The Single User Login system is being updated over the next few months. This is the system which allows users to fill out the login form on one Wikimedia site and get logged in on all others at the same time. It needs to be updated because of the ways that browsers are increasingly restricting cross-domain cookies. To accommodate these restrictions, login and account creation pages will move to a central domain, but it will still appear to the user as if they are on the originating wiki. The updated code will be enabled this week for users on test wikis. This change is planned to roll out to all users during February and March. See [[mw:Special:MyLanguage/MediaWiki Platform Team/SUL3#Deployment|the SUL3 project page]] for more details and a timeline.

'''Updates for editors'''
* On wikis with [[mw:Special:MyLanguage/Extension:PageAssessments|PageAssessments]] installed, you can now [[mw:Special:MyLanguage/Extension:PageAssessments#Search|filter search results]] to pages in a given WikiProject by using the &lt;code dir=ltr&gt;inproject:&lt;/code&gt; keyword.

'''Updates for technical contributors'''
* [[File:Octicons-tools.svg|12px|link=|class=skin-invert|Advanced item]] Wikimedia REST API users, such as bot operators and tool maintainers, may be affected by ongoing upgrades. Starting the week of January 13, we will begin rerouting [[phab:T374683|some page content endpoints]] from RESTbase to the newer MediaWiki REST API endpoints for all wiki projects. This change was previously available on testwiki and should not affect existing functionality, but active users of the impacted endpoints may raise issues directly to the [[phab:project/view/6931/|MediaWiki Interfaces Team]] in Phabricator if they arise.
* Toolforge tool maintainers can now share their feedback on Toolforge UI, an initiative to provide a web platform that allows creating and managing Toolforge tools through a graphic interface, in addition to existing command-line workflows. This project aims to streamline active maintainers’ tasks, as well as make registration and deployment processes more accessible for new tool creators. The initiative is still at a very early stage, and the Cloud Services team is in the process of collecting feedback from the Toolforge community to help shape the solution to their needs. [[wikitech:Wikimedia Cloud Services team/EnhancementProposals/Toolforge UI|Read more and share your thoughts about Toolforge UI]]. 
* [[File:Octicons-tools.svg|12px|link=|class=skin-invert|Advanced item]] For tool and library developers who use the OAuth system: The identity endpoint used for [[mw:Special:MyLanguage/OAuth/For Developers#Identifying the user|OAuth 1]] and [[mw:Special:MyLanguage/OAuth/For Developers#Identifying the user 2|OAuth 2]] returned a JSON object with an integer in its &lt;code&gt;sub&lt;/code&gt; field, which was incorrect (the field must always be a string). This has been fixed; the fix will be deployed to Wikimedia wikis on the week of January 13. [https://phabricator.wikimedia.org/T382139]
* Many wikis currently use [[:mw:Parsoid/Parser Unification/Cite CSS|Cite CSS]] to render custom footnote markers in Parsoid output. Starting January 20 these rules will be disabled, but the developers ask you to ''not'' clean up your &lt;bdi lang=&quot;en&quot; dir=&quot;ltr&quot;&gt;[[MediaWiki:Common.css]]&lt;/bdi&gt; until February 20 to avoid issues during the migration. Your wikis might experience some small changes to footnote markers in Visual Editor and when using experimental Parsoid read mode, but if there are changes these are expected to bring the rendering in line with the legacy parser output. [https://phabricator.wikimedia.org/T370027]

'''Meetings and events'''

'''Updates for editors'''
* Administrators can mass-delete multiple pages created by a user or IP address using [[mw:Special:MyLanguage/Extension:Nuke|Extension:Nuke]]. It previously only allowed deletion of pages created in the last 30 days. It can now delete pages from the last 90 days, provided it is targeting a specific user or IP address. [https://phabricator.wikimedia.org/T380846]
* On [[phab:P72148|wikis that use]] the [[mw:Special:MyLanguage/Help:Patrolled edits|Patrolled edits]] feature, when the rollback feature is used to revert an unpatrolled page revision, that revision will now be marked as &quot;manually patrolled&quot; instead of &quot;autopatrolled&quot;, which is more accurate. Some editors that use [[mw:Special:MyLanguage/Help:New filters for edit review/Filtering|filters]] on Recent Changes may need to update their filter settings.

* iOS Wikipedia App users worldwide can now access a [[mw:Special:MyLanguage/Wikimedia Apps/Team/iOS/Personalized Wikipedia Year in Review/How your data is used|personalized Year in Review]] feature, which provides insights based on their reading and editing history on Wikipedia. This project is part of a broader effort to help welcome new readers as they discover and interact with encyclopedic content.
* [[File:Octicons-gift.svg|12px|link=|class=skin-invert|Wishlist item]] Edit patrollers now have a new feature available that can highlight potentially problematic new pages. When a page is created with the same title as a page which was previously deleted, a tag ('Recreated') will now be added, which users can filter for in [[{{#special:RecentChanges}}]] and [[{{#special:NewPages}}]]. [https://phabricator.wikimedia.org/T56145]
* Later this week, there will be a new warning for editors if they attempt to create a redirect that links to another redirect (a [[mw:Special:MyLanguage/Help:Redirects#Double redirects|double redirect]]). The feature will recommend that they link directly to the second redirect's target page. Thanks to the user SomeRandomDeveloper for this improvement. [https://phabricator.wikimedia.org/T326056]
* [[File:Octicons-tools.svg|12px|link=|class=skin-invert|Advanced item]] Wikimedia wikis allow [[w:en:WebAuthn|WebAuthn]]-based second factor checks (such as hardware tokens) during login, but the feature is [[m:Community Wishlist Survey 2023/Miscellaneous/Fix security key (WebAuthn) support|fragile]] and has very few users.

There will also be one field rename: in the &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;mediawiki_user_history&lt;/code&gt;&lt;/bdi&gt; dump, the &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;anonymous&lt;/code&gt;&lt;/bdi&gt; field will be renamed to &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;is_anonymous&lt;/code&gt;&lt;/bdi&gt;. The changes will take effect with the next release of the dumps in February. [https://lists.wikimedia.org/hyperkitty/list/wikitech-l@lists.wikimedia.org/thread/LKMFDS62TXGDN6L56F4ABXYLN7CSCQDI/]

'''Updates for editors'''
* Editors who use the &quot;Special characters&quot; editing-toolbar menu can now see the 32 special characters you have used most recently, across editing sessions on that wiki. This change should help make it easier to find the characters you use most often. The feature is in both the 2010 wikitext editor and VisualEditor. [https://phabricator.wikimedia.org/T110722]
* Editors using the 2010 wikitext editor can now create sublists with correct indentation by selecting the line(s) you want to indent and then clicking the toolbar buttons.[https://phabricator.wikimedia.org/T380438] You can now also insert &lt;code&gt;&lt;nowiki&gt;&lt;code&gt;&lt;/nowiki&gt;&lt;/code&gt; tags using a new toolbar button.[https://phabricator.wikimedia.org/T383010] Thanks to user stjn for these improvements.
* Help is needed to ensure the [[mw:Special:MyLanguage/Citoid/Enabling Citoid on your wiki|citation generator]] works properly on each wiki.
** (1) Administrators should update the local versions of the page &lt;code dir=ltr&gt;MediaWiki:Citoid-template-type-map.json&lt;/code&gt; to include entries for &lt;code dir=ltr&gt;preprint&lt;/code&gt;, &lt;code dir=ltr&gt;standard&lt;/code&gt;, and &lt;code dir=ltr&gt;dataset&lt;/code&gt;; Here are example diffs to replicate [https://en.wikipedia.org/w/index.php?title=MediaWiki%3ACitoid-template-type-map.json&amp;diff=1189164774&amp;oldid=1165783565 for 'preprint'] and [https://en.wikipedia.org/w/index.php?title=MediaWiki%3ACitoid-template-type-map.json&amp;diff=1270832208&amp;oldid=1270828390 for 'standard' and 'dataset'].
** (2.1) If the citoid map in the citation template used for these types of references is missing, [[mediawikiwiki:Citoid/Enabling Citoid on your wiki#Step 2.a: Create a 'citoid' maps value for each citation template|one will need to be added]]. (2.2) If the citoid map does exist, the TemplateData will need to be updated to include new field names. Here are example updates [https://en.wikipedia.org/w/index.php?title=Template%3ACitation%2Fdoc&amp;diff=1270829051&amp;oldid=1262470053 for 'preprint'] and [https://en.wikipedia.org/w/index.php?title=Template%3ACitation%2Fdoc&amp;diff=1270831369&amp;oldid=1270829480 for 'standard' and 'dataset']. The new fields that may need to be supported are &lt;code dir=ltr&gt;archiveID&lt;/code&gt;, &lt;code dir=ltr&gt;identifier&lt;/code&gt;, &lt;code dir=ltr&gt;repository&lt;/code&gt;, &lt;code dir=ltr&gt;organization&lt;/code&gt;, &lt;code dir=ltr&gt;repositoryLocation&lt;/code&gt;, &lt;code dir=ltr&gt;committee&lt;/code&gt;, and &lt;code dir=ltr&gt;versionNumber&lt;/code&gt;. [https://phabricator.wikimedia.org/T383666]
* One new wiki has been created: a {{int:project-localized-name-group-wikipedia/en}} in [[d:Q15637215|Central Kanuri]] ([[w:knc:|&lt;code&gt;w:knc:&lt;/code&gt;]]) [https://phabricator.wikimedia.org/T385181]

'''Weekly highlight'''

* The Product and Technology Advisory Council (PTAC) has published [[m:Special:MyLanguage/Product and Technology Advisory Council/February 2025 draft PTAC recommendation for feedback|a draft of their recommendations]] for the Wikimedia Foundation's Product and Technology department. They have recommended focusing on [[m:Special:MyLanguage/Product and Technology Advisory Council/February 2025 draft PTAC recommendation for feedback/Mobile experiences|mobile experiences]], particularly contributions. They request community [[m:Talk:Product and Technology Advisory Council/February 2025 draft PTAC recommendation for feedback|feedback at the talk page]] by 21 February.

'''Updates for editors'''
* The &quot;Special pages&quot; portlet link will be moved from the &quot;Toolbox&quot; into the &quot;Navigation&quot; section of the main menu's sidebar by default. This change is because the Toolbox is intended for tools relating to the current page, not tools relating to the site, so the link will be more logically and consistently located. To modify this behavior and update CSS styling, administrators can follow the instructions at [[phab:T385346|T385346]]. [https://phabricator.wikimedia.org/T333211]
* As part of this year's work around improving the ways readers discover content on the wikis, the Web team will be running an experiment with a small number of readers that displays some suggestions for related or interesting articles within the search bar. Please check out [[mw:Special:MyLanguage/Reading/Web/Content Discovery Experiments#Experiment 1: Display article recommendations in more prominent locations, search|the project page]] for more information.
* [[File:Octicons-tools.svg|12px|link=|class=skin-invert|Advanced item]] Template editors who use TemplateStyles can now customize output for users with specific accessibility needs by using accessibility related media queries (&lt;code dir=ltr&gt;[https://developer.mozilla.org/en-US/docs/Web/CSS/@media/prefers-reduced-motion prefers-reduced-motion]&lt;/code&gt;, &lt;code dir=ltr&gt;[https://developer.mozilla.org/en-US/docs/Web/CSS/@media/prefers-reduced-transparency prefers-reduced-transparency]&lt;/code&gt;, &lt;code dir=ltr&gt;[https://developer.mozilla.org/en-US/docs/Web/CSS/@media/prefers-contrast prefers-contrast]&lt;/code&gt;, and &lt;code dir=ltr&gt;[https://developer.mozilla.org/en-US/docs/Web/CSS/@media/forced-colors forced-colors]&lt;/code&gt;).

For example, the global blocks log will now be shown directly on the {{#special:CentralAuth}} page, similarly to global locks, to simplify the workflows for stewards. [https://phabricator.wikimedia.org/T377024]

'''Updates for technical contributors'''
* Wikidata [[d:Special:MyLanguage/Help:Default values for labels and aliases|now supports a special language as a &quot;default for all languages&quot;]] for labels and aliases. This is to avoid excessive duplication of the same information across many languages. If your Wikidata queries use labels, you may need to update them as some existing labels are getting removed. [https://phabricator.wikimedia.org/T312511]
* The function &lt;code dir=&quot;ltr&quot;&gt;getDescription&lt;/code&gt; was invoked on every Wiki page read and accounts for ~2.5% of a page's total load time. The calculated value will now be cached, reducing load on Wikimedia servers. [https://phabricator.wikimedia.org/T383660]
* As part of the RESTBase deprecation [[mw:RESTBase/deprecation|effort]], the &lt;code dir=&quot;ltr&quot;&gt;/page/related&lt;/code&gt; endpoint has been blocked as of February 6, 2025, and will be removed soon. This timeline was chosen to align with the deprecation schedules for older Android and iOS versions. The stable alternative is the &quot;&lt;code dir=&quot;ltr&quot;&gt;morelike&lt;/code&gt;&quot; action API in MediaWiki, and [[gerrit:c/mediawiki/services/mobileapps/+/982154/13/pagelib/src/transform/FooterReadMore.js|a migration example]] is available. The MediaWiki Interfaces team [[phab:T376297|can be contacted]] for any questions.

'''Weekly highlight'''
* Communities using growth tools can now showcase one event on the &lt;code&gt;{{#special:Homepage}}&lt;/code&gt; for newcomers. This feature will help newcomers to be informed about editing activities they can participate in. Administrators can create a new event to showcase at &lt;code&gt;{{#special:CommunityConfiguration}}&lt;/code&gt;. To learn more about this feature, please read [[diffblog:2025/02/12/community-updates-module-connecting-newcomers-to-your-initiatives/|the Diff post]], have a look [[mw:Special:MyLanguage/Help:Growth/Tools/Community updates module|at the documentation]], or contact [[mw:Talk:Growth|the Growth team]].

'''Updates for editors'''
[[File:Page Frame Features on desktop.png|thumb|Highlighted talk pages improvements]]
* Starting next week, talk pages at these wikis – {{int:project-localized-name-eswiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-frwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-itwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-jawiki/en}} – will get [[diffblog:2024/05/02/making-talk-pages-better-for-everyone/|a new design]]. This change was extensively tested as a Beta feature and is the last step of [[mw:Special:MyLanguage/Talk pages project/Feature summary|talk pages improvements]]. [https://phabricator.wikimedia.org/T379102]
* You can now navigate to view a redirect page directly from its action pages, such as the history page. Previously, you were forced to first go to the redirect target. This change should help editors who work with redirects a lot. Thanks to user stjn for this improvement. [https://phabricator.wikimedia.org/T5324]
* When a Cite reference is reused many times, wikis currently show either numbers like &quot;1.23&quot; or localized alphabetic markers like &quot;a b c&quot; in the reference list. Previously, if there were so many reuses that the alphabetic markers were all used, [[MediaWiki:Cite error references no backlink label|an error message]] was displayed.  As part of the work to [[phab:T383036|modernize Cite customization]], these errors will no longer be shown and instead the backlinks will fall back to showing numeric markers like &quot;1.23&quot; once the alphabetic markers are all used.
* The log entries for each change to an editor's user-groups are now clearer by specifying exactly what has changed, instead of the plain before and after listings. Translators can [[phab:T369466|help to update the localized versions]]. Thanks to user Msz2001 for these improvements.
* A new filter has been added to the [[{{#special:Nuke}}]] tool, which allows administrators to mass delete pages, to enable users to filter for pages in a range of page sizes (in bytes). This allows, for example, deleting pages only of a certain size or below. [https://phabricator.wikimedia.org/T378488]
* Non-administrators can now check which pages are able to be deleted using the [[{{#special:Nuke}}]] tool. Thanks to user MolecularPilot for this and the previous improvements. [https://phabricator.wikimedia.org/T376378]
* [[File:Octicons-sync.svg|12px|link=|class=skin-invert|Recurrent item]] View all {{formatnum:25}} community-submitted {{PLURAL:25|task|tasks}} that were [[m:Special:MyLanguage/Tech/News/Recently resolved community tasks|resolved last week]]. For example, a bug was fixed in the configuration for the AV1 video file format, which enables these files to play again. [https://phabricator.wikimedia.org/T382193]

'''Updates for technical contributors'''
* Parsoid Read Views is going to be rolling out to most Wiktionaries over the next few weeks, following the successful transition of Wikivoyage to Parsoid Read Views last year. For more information, see the [[mw:Special:MyLanguage/Parsoid/Parser Unification|Parsoid/Parser Unification]] project page. [https://phabricator.wikimedia.org/T385923][https://phabricator.wikimedia.org/T371640]
* Developers of tools that run on-wiki should note that &lt;code dir=ltr&gt;mw.Uri&lt;/code&gt; is deprecated. Tools requiring &lt;code dir=ltr&gt;mw.Uri&lt;/code&gt; must explicitly declare &lt;code dir=ltr&gt;mediawiki.Uri&lt;/code&gt; as a ResourceLoader dependency, and should migrate to the browser native &lt;code dir=ltr&gt;URL&lt;/code&gt; API soon.

* Administrators can now customize how the [[m:Special:MyLanguage/User language|Babel feature]] creates categories using [[{{#special:CommunityConfiguration/Babel}}]]. They can rename language categories, choose whether they should be auto-created, and adjust other settings. [https://phabricator.wikimedia.org/T374348]
* The &lt;bdi lang=&quot;en&quot; dir=&quot;ltr&quot;&gt;[https://www.wikimedia.org/ wikimedia.org]&lt;/bdi&gt; portal has been updated – and is receiving some ongoing improvements – to modernize and improve the accessibility of our portal pages. It now has better support for mobile layouts, updated wording and links, and better language support. Additionally, all of the Wikimedia project portals, such as &lt;bdi lang=&quot;en&quot; dir=&quot;ltr&quot;&gt;[https://wikibooks.org wikibooks.org]&lt;/bdi&gt;, now support dark mode when a reader is using that system setting. [https://phabricator.wikimedia.org/T373204][https://phabricator.wikimedia.org/T368221][https://meta.wikimedia.org/wiki/Project_portals]
* One new wiki has been created: a {{int:project-localized-name-group-wiktionary/en}} in [[d:Q33965|Santali]] ([[wikt:sat:|&lt;code&gt;wikt:sat:&lt;/code&gt;]]) [https://phabricator.wikimedia.org/T386619]

'''Updates for editors'''
* All logged-in editors using the mobile view can now edit a full page. The &quot;{{int:Minerva-page-actions-editfull}}&quot; link is accessible from the &quot;{{int:minerva-page-actions-overflow}}&quot; menu in the toolbar. This was previously only available to editors using the [[mw:Special:MyLanguage/Reading/Web/Advanced mobile contributions|Advanced mobile contributions]] setting. [https://phabricator.wikimedia.org/T387180]
* Interface administrators can now help to remove the deprecated Cite CSS code matching &quot;&lt;code dir=&quot;ltr&quot;&gt;mw-ref&lt;/code&gt;&quot; from their local &lt;bdi lang=&quot;en&quot; dir=&quot;ltr&quot;&gt;[[MediaWiki:Common.css]]&lt;/bdi&gt;. The list of wikis in need of cleanup, and the code to remove, [https://global-search.toolforge.org/?q=mw-ref%5B%5E-a-z%5D&amp;regex=1&amp;namespaces=8&amp;title=.*css can be found with this global search] and in [https://ace.wikipedia.org/w/index.php?title=MediaWiki:Common.css&amp;oldid=145662#L-139--L-144 this example], and you can learn more about how to help on the [[mw:Parsoid/Parser Unification/Cite CSS|CSS migration project page]]. The Cite footnote markers (&quot;&lt;code dir=&quot;ltr&quot;&gt;[1]&lt;/code&gt;&quot;) are now rendered by [[mw:Special:MyLanguage/Parsoid|Parsoid]], and the deprecated CSS is no longer needed. The CSS for backlinks (&quot;&lt;code dir=&quot;ltr&quot;&gt;mw:referencedBy&lt;/code&gt;&quot;) should remain in place for now. This cleanup is expected to cause no visible changes for readers. Please help to remove this code before March 20, after which the development team will do it for you.
* When editors embed a file (e.g. &lt;code&gt;&lt;nowiki&gt;[[File:MediaWiki.png]]&lt;/nowiki&gt;&lt;/code&gt;) on a page that is protected with cascading protection, the software will no longer restrict edits to the file description page, only to new file uploads.[https://phabricator.wikimedia.org/T24521] In contrast, transcluding a file description page (e.g. &lt;code&gt;&lt;nowiki&gt;{{:File:MediaWiki.png}}&lt;/nowiki&gt;&lt;/code&gt;) will now restrict edits to the page.[https://phabricator.wikimedia.org/T62109]
* When editors revert a file to an earlier version it will now require the same permissions as ordinarily uploading a new version of the file. The software now checks for 'reupload' or 'reupload-own' rights,[https://phabricator.wikimedia.org/T304474] and respects cascading protection.[https://phabricator.wikimedia.org/T140010]
* When administrators are listing pages for deletion with the Nuke tool, they can now also list associated talk pages and redirects for deletion, alongside pages created by the target, rather than needing to manually delete these pages afterwards. [https://phabricator.wikimedia.org/T95797]
* The [[m:Special:MyLanguage/Tech/News/2025/03|previously noted]] update to Single User Login, which will accommodate browser restrictions on cross-domain cookies by moving login and account creation to a central domain, will now roll out to all users during March and April. The team plans to enable it for all new account creation on [[wikitech:Deployments/Train#Tuesday|Group0]] wikis this week. See [[mw:Special:MyLanguage/MediaWiki Platform Team/SUL3#Deployment|the SUL3 project page]] for more details and an updated timeline.

'''Updates for editors'''
* Editors who use password managers at multiple wikis may notice changes in the future. The way that our wikis provide information to password managers about reusing passwords across domains has recently been updated, so some password managers might now offer you login credentials that you saved for a different Wikimedia site. Some password managers already did this, and are now doing it for more Wikimedia domains. This is part of the [[mw:Special:MyLanguage/MediaWiki Platform Team/SUL3|SUL3 project]] which aims to improve how our unified login works, and to keep it compatible with ongoing changes to the web-browsers we use. [https://phabricator.wikimedia.org/T385520][https://phabricator.wikimedia.org/T384844]
* The Wikipedia Apps Team is inviting interested users to help improve Wikipedia’s offline and limited internet use. After discussions in [[m:Afrika Baraza|Afrika Baraza]] and the last [[m:Special:MyLanguage/ESEAP Hub/Meetings|ESEAP call]], key challenges like search, editing, and offline access are being explored, with upcoming focus groups to dive deeper into these topics. All languages are welcome, and interpretation will be available. Want to share your thoughts? [[mw:Special:MyLanguage/Wikimedia Apps/Improving Wikipedia Mobile Apps for Offline &amp; Limited Internet Use|Join the discussion]] or email &lt;bdi lang=&quot;en&quot; dir=&quot;ltr&quot;&gt;aramadan@wikimedia.org&lt;/bdi&gt;!
* All wikis will be read-only for a few minutes on March 19. This is planned at [https://zonestamp.toolforge.org/1742392800 14:00 UTC]. More information will be published in Tech News and will also be posted on individual wikis in the coming weeks.

* The latest quarterly [[mw:Special:MyLanguage/Growth/Newsletters/33|Growth newsletter]] is available. It includes: the launch of the Community Updates module, the most recent changes in Community Configuration, and the upcoming test of in-article suggestions for first-time editors.
* An old API that was previously used in the Android Wikipedia app is being removed at the end of March. There are no current software uses, but users of the app with a version that is older than 6 months by the time of removal (2025-03-31), will no longer have access to the Suggested Edits feature, until they update their app. You can [[diffblog:2025/02/24/sunset-of-wikimedia-recommendation-api/|read more details about this change]].

'''Weekly highlight'''
* Twice a year, around the equinoxes, the Wikimedia Foundation's Site Reliability Engineering (SRE) team performs [[m:Special:MyLanguage/Tech/Server switch|a datacenter server switchover]], redirecting all traffic from one primary server to its backup. This provides reliability in case of a crisis, as we can always fall back on the other datacenter. [http://listen.hatnote.com/ Thanks to the Listen to Wikipedia] tool, you can hear the switchover take place: Before it begins, you'll hear the steady stream of edits; Then, as the system enters a brief read-only phase, the sound stops for a couple of minutes, before resuming after the switchover. You can [[diffblog:2025/03/12/hear-that-the-wikis-go-silent-twice-a-year/|read more about the background and details of this process on the Diff blog]]. If you want to keep an ear out for the next server switchover, listen to the wikis on [https://zonestamp.toolforge.org/1742392800 March 19 at 14:00 UTC].

'''Updates for editors'''

* The [https://test.wikipedia.org/w/index.php?title=Special:ContentTranslation&amp;filter-type=automatic&amp;filter-id=previous-edits&amp;active-list=suggestions&amp;from=en&amp;to=es improved Content Translation tool dashboard] is now available in [[phab:T387820|10 Wikipedias]] and will be available for all Wikipedias [[phab:T387821|soon]]. With [[mw:Special:MyLanguage/Content translation#Improved translation experience|the unified dashboard]], desktop users can now: Translate new sections of an article; Discover and access topic-based [https://ig.m.wikipedia.org/w/index.php?title=Special:ContentTranslation&amp;active-list=suggestions&amp;from=en&amp;to=ig&amp;filter-type=automatic&amp;filter-id=previous-edits article suggestion filters] (initially available only for mobile device users); Discover and access the [[mw:Special:MyLanguage/Translation suggestions: Topic-based &amp; Community-defined lists|Community-defined lists]] filter, also known as &quot;Collections&quot;, from wiki-projects and campaigns.
* On Wikimedia Commons, a [[c:Commons:WMF support for Commons/Upload Wizard Improvements#Improve category selection|new system to select the appropriate file categories]] has been introduced: if a category has one or more subcategories, users will be able to click on an arrow that will open the subcategories directly within the form, and choose the correct one. The parent category name will always be shown on top, and it will always be possible to come back to it. This should decrease the amount of work for volunteers in fixing/creating new categories. The change is also available on mobile. These changes are part of planned improvements to the UploadWizard.
* The Community Tech team is seeking wikis to join a pilot for the [[m:Special:MyLanguage/Community Wishlist Survey 2023/Multiblocks|Multiblocks]] feature and a refreshed Special:Block page in late March. Multiblocks enables administrators to impose multiple different types of blocks on the same user at the same time. If you are an admin or steward and would like us to discuss joining the pilot with your community, please leave a message on the [[m:Talk:Community Wishlist Survey 2023/Multiblocks|project talk page]].
* Starting March 25, the Editing team will test a new feature for Edit Check at [[phab:T384372|12 Wikipedias]]: [[mw:Special:MyLanguage/Help:Edit check#Multi-check|Multi-Check]]. Half of the newcomers on these wikis will see all [[mw:Special:MyLanguage/Help:Edit check#ref|Reference Checks]] during their edit session, while the other half will continue seeing only one. The goal of this test is to see if users are confused or discouraged when shown multiple Reference Checks (when relevant) within a single editing session. At these wikis, the tags used on edits that show References Check will be simplified, as multiple tags could be shown within a single edit. Changes to the tags are documented [[phab:T373949|on Phabricator]]. [https://phabricator.wikimedia.org/T379131]
* The [[m:Special:MyLanguage/Global reminder bot|Global reminder bot]], which is a service for notifying users that their temporary user-rights are about to expire, now supports using the localized name of the user-rights group in the message heading. Translators can see the [[m:Global reminder bot/Translation|listing of existing translations and documentation]] to check if their language needs updating or creation.
* The [[Special:GlobalPreferences|GlobalPreferences]] gender setting, which is used for how the software should refer to you in interface messages, now works as expected by overriding the local defaults. [https://phabricator.wikimedia.org/T386584]

'''Updates for technical contributors'''
* Later this week, the way that Codex styles are loaded will be changing. There is a small risk that this may result in unstyled interface message boxes on certain pages. User generated content (e.g. templates) is not impacted. Gadgets may be impacted. If you see any issues [[phab:T388847|please report them]]. See the linked task for details, screenshots, and documentation on how to fix any affected gadgets.

Please share your feedback on the talkpage, in any language, ideally before the end of April.

'''Updates for editors'''
* The [[mw:Special:MyLanguage/Help:Extension:CampaignEvents|CampaignEvents extension]] will be released to multiple wikis (see [[m:Special:MyLanguage/CampaignEvents/Deployment status#Global Deployment Plan|deployment plan]] for details) in April 2025, and the team has begun the process of engaging communities on the identified wikis. The extension provides tools to organize, manage, and promote collaborative activities (like events, edit-a-thons, and WikiProjects) on the wikis. The extension has three tools: [[m:Special:MyLanguage/Event Center/Registration|Event Registration]], [[m:Special:MyLanguage/CampaignEvents/Collaboration list|Collaboration List]], and [[m:Special:MyLanguage/Campaigns/Foundation Product Team/Invitation list|Invitation Lists]]. It is currently on 13 Wikipedias, including English Wikipedia, French Wikipedia, and Spanish Wikipedia, as well as Wikidata. Questions or requests can be directed to the [[mw:Help talk:Extension:CampaignEvents|extension talk page]] or in Phabricator (with &lt;bdi lang=&quot;en&quot; dir=&quot;ltr&quot; style=&quot;white-space: nowrap;&quot;&gt;#campaigns-product-team&lt;/bdi&gt; tag).
* Starting the week of March 31st, wikis will be able to set which user groups can view private registrants in [[m:Special:MyLanguage/Event Center/Registration|Event Registration]], as part of the [[mw:Special:MyLanguage/Help:Extension:CampaignEvents|CampaignEvents]] extension. By default, event organizers and the local wiki admins will be able to see private registrants. This is a change from the current behavior, in which only event organizers can see private registrants. Wikis can change the default setup by [[m:Special:MyLanguage/Requesting wiki configuration changes|requesting a configuration change]] in Phabricator (and adding the &lt;bdi lang=&quot;en&quot; dir=&quot;ltr&quot; style=&quot;white-space: nowrap;&quot;&gt;#campaigns-product-team&lt;/bdi&gt; tag). Participants of past events can cancel their registration at any time.
* Administrators at wikis that have a customized &lt;bdi lang=&quot;en&quot; dir=&quot;ltr&quot;&gt;[[MediaWiki:Sidebar]]&lt;/bdi&gt; should check that it contains an entry for the {{int:specialpages}} listing. If it does not, they should add it using &lt;code dir=ltr style=&quot;white-space: nowrap;&quot;&gt;* specialpages-url|specialpages&lt;/code&gt;. Wikis with a default sidebar will see the link moved from the page toolbox into the sidebar menu in April. [https://phabricator.wikimedia.org/T388927]
* The Minerva skin (mobile web) combines both Notice and Alert notifications within the bell icon ([[File:OOjs UI icon bell.svg|16px|link=|class=skin-invert]]). There was a long-standing bug where an indication for new notifications was only shown if you had unseen Alerts. This bug is now fixed. In the future, Minerva users will notice a counter atop the bell icon when you have 1 or more unseen Notices and/or Alerts. [https://phabricator.wikimedia.org/T344029]

'''Updates for technical contributors'''
* VisualEditor has introduced a [[mw:VisualEditor/Hooks|new client-side hook]] for developers to use when integrating with the VisualEditor target lifecycle. This hook should replace the existing lifecycle-related hooks, and be more consistent between different platforms. In addition, the new hook will apply to uses of VisualEditor outside of just full article editing, allowing gadgets to interact with the editor in DiscussionTools as well. The Editing Team intends to deprecate and eventually remove the old lifecycle hooks, so any use cases that this new hook does not cover would be of interest to them and can be [[phab:T355555|shared in the task]].
* Developers who use the &lt;code dir=ltr&gt;mw.Api&lt;/code&gt; JavaScript library, can now identify the tool using it with the &lt;code dir=ltr&gt;userAgent&lt;/code&gt; parameter: &lt;code dir=ltr&gt;var api = new mw.Api( { userAgent: 'GadgetNameHere/1.0.1' } );&lt;/code&gt;. If you maintain a gadget or user script, please set a user agent, because it helps with library and server maintenance and with differentiating between legitimate and illegitimate traffic.

'''Updates for editors'''
* The Editing team is working on a new [[mw:Special:MyLanguage/Edit Check|Edit check]]: [[mw:Special:MyLanguage/Edit check#26 March 2025|Peacock check]]. This check's goal is to identify non-neutral terms while a user is editing a wikipage, so that they can be informed that their edit should perhaps be changed before they publish it. This project is at the early stages, and the team is looking for communities' input: [[phab:T389445|in this Phabricator task]], they are gathering on-wiki policies, templates used to tag non-neutral articles, and the terms (jargon and keywords) used in edit summaries for the languages they are currently researching. You can participate by editing the table on Phabricator, commenting on the task, or directly messaging [[m:user:Trizek (WMF)|Trizek (WMF)]].
* [[mw:Special:MyLanguage/MediaWiki Platform Team/SUL3|Single User Login]] has now been updated on all wikis to move login and account creation to a central domain. This makes user login compatible with browser restrictions on cross-domain cookies, which have prevented users of some browsers from staying logged in.

'''Updates for technical contributors'''
* Starting on March 31st, the MediaWiki Interfaces team will begin a limited release of generated OpenAPI specs and a SwaggerUI-based sandbox experience for [[mw:Special:MyLanguage/API:REST API|MediaWiki REST APIs]]. They invite developers from a limited group of non-English Wikipedia communities (Arabic, German, French, Hebrew, Interlingua, Dutch, Chinese) to review the documentation and experiment with the sandbox in their preferred language. In addition to these specific Wikipedia projects, the sandbox and OpenAPI spec will be available on the [[testwiki:Special:RestSandbox|on the test wiki REST Sandbox special page]] for developers with English as their preferred language. During the preview period, the MediaWiki Interfaces Team also invites developers to [[mw:MediaWiki Interfaces Team/Feature Feedback/REST Sandbox|share feedback about your experience]]. The preview will last for approximately 2 weeks, after which the sandbox and OpenAPI specs will be made available across all wiki projects.

'''In depth'''
* Sometimes a small, [[gerrit:c/operations/cookbooks/+/1129184|one line code change]] can have great significance: in this case, it means that for the first time in years we're able to run all of the stack serving &lt;bdi lang=&quot;en&quot; dir=&quot;ltr&quot;&gt;[http://maps.wikimedia.org/ maps.wikimedia.org]&lt;/bdi&gt; - a host dedicated to serving our wikis and their multi-lingual maps needs - from a single core datacenter, something we test every time we perform a [[m:Special:MyLanguage/Tech/Server switch|datacenter switchover]]. This is important because it means that in case one of our datacenters is affected by a catastrophe, we'll still be able to serve the site. This change is the result of [[phab:T216826|extensive work]] by two developers on porting the last component of the maps stack over to [[w:en:Kubernetes|kubernetes]], where we can allocate resources more efficiently than before, thus we're able to withstand more traffic in a single datacenter. This work involved a lot of complicated steps because this software, and the software libraries it uses, required many long overdue upgrades. This type of work makes the Wikimedia infrastructure more sustainable.

'''Meetings and events'''
* [[mw:Special:MyLanguage/MediaWiki Users and Developers Workshop Spring 2025|MediaWiki Users and Developers Workshop Spring 2025]] is happening in Sandusky, USA, and online, from 14–16 May 2025. The workshop will feature discussions around the usage of MediaWiki software by and within companies in different industries and will inspire and onboard new users. Registration and presentation signup is now available at the workshop's website.

'''Weekly highlight'''
* Later this week, the default thumbnail size will be increased from 220px to 250px. This changes how pages are shown in all wikis and has been requested by some communities for many years, but wasn't previously possible due to technical limitations. [https://phabricator.wikimedia.org/T355914]
* File thumbnails are now stored in discrete sizes. If a page specifies a thumbnail size that's not among the standard sizes (20, 40, 60, 120, 250, 330, 500, 960), then MediaWiki will pick the closest larger thumbnail size but will tell the browser to downscale it to the requested size. In these cases, nothing will change visually but users might load slightly larger images. If it doesn't matter which thumbnail size is used in a page, please pick one of the standard sizes to avoid the extra in-browser down-scaling step.

'''Updates for editors'''
* The Wikimedia Foundation are working on a system called [[m:Edge Uniques|Edge Uniques]] which will enable [[:w:en:A/B testing|A/B testing]], help protect against [[:w:en:Denial-of-service attack|Distributed denial-of-service attacks]] (DDoS attacks), and make it easier to understand how many visitors the Wikimedia sites have. This is so that they can more efficiently build tools which help readers, and make it easier for readers to find what they are looking for.
* To improve security for users, a small percentage of logins will now require that the account owner input a one-time password [[mw:Special:MyLanguage/Help:Extension:EmailAuth|emailed to their account]]. It is recommended that you [[Special:Preferences#mw-prefsection-personal-email|check]] that the email address on your account is set correctly, and that it has been confirmed, and that you have an email set for this purpose. [https://phabricator.wikimedia.org/T390662]
* &quot;Are you interested in taking a short survey to improve tools used for reviewing or reverting edits on your Wiki?&quot; This question will be [[phab:T389401|asked at 7 wikis starting next week]], on Recent Changes and Watchlist pages. The [[mw:Special:MyLanguage/Moderator Tools|Moderator Tools team]] wants to know more about activities that involve looking at new edits made to your Wikimedia project, and determining whether they adhere to your project's policies.
* On April 15, the full Wikidata graph will no longer be supported on &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;[https://query.wikidata.org/ query.wikidata.org]&lt;/bdi&gt;. After this date, scholarly articles will be available through &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot; style=&quot;white-space:nowrap;&quot;&gt;[https://query-scholarly.wikidata.org/ query-scholarly.wikidata.org]&lt;/bdi&gt;, while the rest of the data hosted on Wikidata will be available through the &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;[https://query.wikidata.org/ query.wikidata.org]&lt;/bdi&gt; endpoint. This is part of the scheduled split of the Wikidata Graph, which was [[d:Special:MyLanguage/Wikidata:SPARQL query service/WDQS backend update/September 2024 scaling update|announced in September 2024]].

'''Updates for editors'''
* [[f:Special:MyLanguage/Wikifunctions:Main Page|Wikifunctions]] is now integrated with [[w:dag:Solɔɣu|Dagbani Wikipedia]] since April 15. It is the first project that will be able to call [[f:Special:MyLanguage/Wikifunctions:Introduction|functions from Wikifunctions]] and integrate them in articles. A function is something that takes one or more inputs and transforms them into a desired output, such as adding up two numbers, converting miles into metres, calculating how much time has passed since an event, or declining a word into a case. Wikifunctions will allow users to do that through a simple call of [[f:Special:MyLanguage/Wikifunctions:Catalogue|a stable and global function]], rather than via a local template. [https://www.wikifunctions.org/wiki/Special:MyLanguage/Wikifunctions:Status_updates/2025-04-16]

'''Updates for editors'''
* For wikis that have the [[m:Special:MyLanguage/CampaignEvents/Deployment status|CampaignEvents extension enabled]], two new feature improvements have been released:
** Admins can now choose which namespaces are permitted for [[m:Special:MyLanguage/Event Center/Registration|Event Registration]] via [[mw:Special:MyLanguage/Community Configuration|Community Configuration]] ([[mw:Special:MyLanguage/Help:Extension:CampaignEvents/Registration/Permitted namespaces|documentation]]). The default setup is for event registration to be permitted in the Event namespace, but other namespaces (such as the project namespace or WikiProject namespace) can now be added. With this change, communities like WikiProjects can now more easily use Event Registration for their collaborative activities.
** Editors can now [[mw:Special:MyLanguage/Transclusion|transclude]] the Collaboration List on a wiki page ([[mw:Special:MyLanguage/Help:Extension:CampaignEvents/Collaboration list/Transclusion|documentation]]). The Collaboration List is an automated list of events and WikiProjects on the wikis, accessed via {{#special:AllEvents}} ([[w:en:Special:AllEvents|example]]). Now, the Collaboration List can be added to all sorts of wiki pages, such as: a wiki mainpage, a WikiProject page, an affiliate page, an event page, or even a user page.

'''Updates for technical contributors'''
* Developers who use the &lt;code dir=ltr&gt;moment&lt;/code&gt; library in gadgets and user scripts should revise their code to use alternatives like the &lt;code dir=ltr&gt;Intl&lt;/code&gt; library or the new &lt;code dir=ltr&gt;mediawiki.DateFormatter&lt;/code&gt; library. The &lt;code dir=ltr&gt;moment&lt;/code&gt; library has been deprecated and will begin to log messages in the developer console. You can see a global search for current uses, and [[phab:T392532|ask related questions in this Phabricator task]].
* Developers who maintain a tool that queries the Wikidata term store tables (&lt;code dir=ltr style=&quot;white-space: nowrap;&quot;&gt;wbt_*&lt;/code&gt;) need to update their code to connect to a separate database cluster. These tables are being split into a separate database cluster. Tools that query those tables via the wiki replicas must be adapted to connect to the new cluster instead. [[wikitech:News/2025 Wikidata term store database split|Documentation and related links are available]]. [https://phabricator.wikimedia.org/T390954]

'''Weekly highlight'''
* The Editing Team and the Machine Learning Team are working on a new check for newcomers: [[mw:Edit check/Peacock check|Peacock check]]. Using a prediction model, this check will encourage editors to improve the tone of their edits, using artificial intelligence. We invite volunteers to review the first version of the Peacock language model for the following languages: Arabic, Spanish, Portuguese, English, and Japanese. Users from these wikis interested in reviewing this model are [[mw:Edit check/Peacock check/model test|invited to sign up at MediaWiki.org]]. The deadline to sign up is on May 23, which will be the start date of the test.

'''Updates for editors'''

* From May 20, 2025, [[m:Special:MyLanguage/Oversight policy|oversighters]] and [[m:Special:MyLanguage/Meta:CheckUsers|checkusers]] will need to have their accounts secured with two-factor authentication (2FA) to be able to use their advanced rights. All users who belong to these two groups and do not have 2FA enabled have been informed. In the future, this requirement may be extended to other users with advanced rights. [[m:Special:MyLanguage/Mandatory two-factor authentication for users with some extended rights|Learn more]].
* [[File:Octicons-gift.svg|12px|link=|class=skin-invert|Wishlist item]]  [[m:Special:MyLanguage/Community Wishlist Survey 2023/Multiblocks|Multiblocks]] will begin mass deployment by the end of the month: all non-Wikipedia projects plus Catalan Wikipedia will adopt Multiblocks in the week of May 26, while all other Wikipedias will adopt it in the week of June 2. Please [[m:Talk:Community Wishlist Survey 2023/Multiblocks|contact the team]] if you have concerns. Administrators can test the new user interface now on your own wiki by browsing to [{{fullurl:Special:Block|usecodex=1}} {{#special:Block}}?usecodex=1], and can test the full multiblocks functionality [[testwiki:Special:Block|on testwiki]]. Multiblocks is the feature that makes it possible for administrators to impose different types of blocks on the same user at the same time. See the [[mw:Special:MyLanguage/Help:Manage blocks|help page]] for more information. [https://phabricator.wikimedia.org/T377121]
* Later this week, the [[{{#special:SpecialPages}}]] listing of almost all special pages will be updated with a new design. This page has been [[phab:T219543|redesigned]] to improve the user experience in a few ways, including: The ability to search for names and aliases of the special pages, sorting, more visible marking of restricted special pages, and a more mobile-friendly look. The new version can be [https://meta.wikimedia.beta.wmflabs.org/wiki/Special:SpecialPages previewed] at Beta Cluster now, and feedback shared in the task. [https://phabricator.wikimedia.org/T219543]
* The [[mw:Special:MyLanguage/Extension:Chart|Chart extension]] is being enabled on more wikis. For a detailed list of when the extension will be enabled on your wiki, please read the [[mw:Special:MyLanguage/Extension:Chart/Project#Deployment Timeline|deployment timeline]].
* [[f:Special:MyLanguage/Wikifunctions:Main Page|Wikifunctions]] will be deployed on May 27 on five Wiktionaries: [[wikt:ha:|Hausa]], [[wikt:ig:|Igbo]], [[wikt:bn:|Bengali]], [[wikt:ml:|Malayalam]], and [[wikt:dv:|Dhivehi/Maldivian]]. This is the second batch of deployment planned for the project. After deployment, the projects will be able to call [[f:Special:MyLanguage/Wikifunctions:Introduction|functions from Wikifunctions]] and integrate them in their pages. A function is something that takes one or more inputs and transforms them into a desired output, such as adding up two numbers, converting miles into metres, calculating how much time has passed since an event, or declining a word into a case. Wikifunctions will allow users to do that through a simple call of [[f:Special:MyLanguage/Wikifunctions:Catalogue|a stable and global function]], rather than via a local template.
* Later this week, the Wikimedia Foundation will publish a hub for [[diffblog:2024/07/09/on-the-value-of-experimentation/|experiments]]. This is to showcase and get user feedback on product experiments. The experiments help the Wikimedia movement [[diffblog:2023/07/13/exploring-paths-for-the-future-of-free-knowledge-new-wikipedia-chatgpt-plugin-leveraging-rich-media-social-apps-and-other-experiments/|understand new users]], how they interact with the internet and how it could affect the Wikimedia movement. Some examples are [[m:Special:MyLanguage/Future Audiences/Generated Video|generated video]], the [[m:Special:MyLanguage/Future Audiences/Roblox game|Wikipedia Roblox speedrun game]] and [[m:Special:MyLanguage/Future Audiences/Discord bot|the Discord bot]].

'''Updates for technical contributors'''
* Gadgets and user scripts that interact with [[{{#special:Block}}]] may need to be updated to work with the new [[mw:Special:MyLanguage/Help:Manage blocks|manage blocks interface]]. Please review the [[mw:Help:Manage blocks/Developers|developer guide]] for more information. If you need help or are unable to adapt your script to the new interface, please let the team know on the [[mw:Help talk:Manage blocks/Developers|talk page]]. [https://phabricator.wikimedia.org/T377121]
* The &lt;code dir=ltr&gt;mw.title&lt;/code&gt; object allows you to get information about a specific wiki page in the [[w:en:Wikipedia:Lua|Lua]] programming language. Starting this week, a new property will be added to the object, named &lt;code dir=ltr&gt;isDisambiguationPage&lt;/code&gt;. This property allows you to check if a page is a disambiguation page, without the need to write a custom function. [https://phabricator.wikimedia.org/T71441]
* [[File:Octicons-tools.svg|15px|link=|class=skin-invert|Advanced item]] User script developers can use a [[toolforge:gitlab-content|new reverse proxy tool]] to load javascript and css from [[gitlab:|gitlab.wikimedia.org]] with &lt;code dir=ltr&gt;mw.loader.load&lt;/code&gt;. The tool's author hopes this will enable collaborative development workflows for user scripts including linting, unit tests, code generation, and code review on &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;gitlab.wikimedia.org&lt;/bdi&gt; without a separate copy-and-paste step to publish scripts to a Wikimedia wiki for integration and acceptance testing. See [[wikitech:Tool:Gitlab-content|Tool:Gitlab-content on Wikitech]] for more information.

'''Meetings and events'''
* The 12th edition of [[m:Special:MyLanguage/Wiki Workshop 2025|Wiki Workshop 2025]], a forum that brings together researchers that explore all aspects of Wikimedia projects, will be held virtually on 21-22 May. Researchers can [https://pretix.eu/wikimedia/wikiworkshop2025/ register now].

'''Weekly highlight'''
* A community-wide discussion about a very delicate issue for the development of [[m:Special:MyLanguage/Abstract Wikipedia|Abstract Wikipedia]] is now open on Meta: where to store the abstract content that will be developed through functions from Wikifunctions and data from Wikidata. The discussion is open until June 12 at [[m:Special:MyLanguage/Abstract Wikipedia/Location of Abstract Content|Abstract Wikipedia/Location of Abstract Content]], and every opinion is welcomed. The decision will be made and communicated after the consultation period by the Foundation.

'''Updates for editors'''
* Since last week, on all wikis except [[phab:T388604|the largest 20]], people using the mobile visual editor will have [[phab:T385851|additional tools in the menu bar]], accessed using the new &lt;code&gt;+&lt;/code&gt; toolbar button. To start, the new menu will include options to add: citations, hieroglyphs, and code blocks. Deployment to the remaining wikis is [[phab:T388605|scheduled]] to happen in June.
* [[File:Octicons-tools.svg|12px|link=|class=skin-invert|Advanced item]] The &lt;code dir=ltr&gt;[[mw:Special:MyLanguage/Help:Extension:ParserFunctions##ifexist|#ifexist]]&lt;/code&gt; parser function will no longer register a link to its target page. This will improve the usefulness of [[{{#special:WantedPages}}]], which will eventually only list pages that are the target of an actual red link. This change will happen gradually as the source pages are updated. [https://phabricator.wikimedia.org/T14019]
* This week, the Moderator Tools team will launch [[mw:Special:MyLanguage/2025 RecentChanges Language Agnostic Revert Risk Filtering|a new filter to Recent Changes]], starting at Indonesian Wikipedia. This new filter highlights edits that are likely to be reverted. The goal is to help Recent Changes patrollers identify potentially problematic edits. Other wikis will benefit from this filter in the future.
* Upon clicking an empty search bar, logged-out users will see suggestions of articles for further reading. The feature will be available on both desktop and mobile. Readers of Catalan, Hebrew, and Italian Wikipedias and some sister projects will receive the change between May 21 and mid-June. Readers of other wikis will receive the change later. The goal is to encourage users to read the wikis more. [[mw:Special:MyLanguage/Reading/Web/Content Discovery Experiments/Search Suggestions|Learn more]].
* Some users of the Wikipedia Android app can use a new feature for readers, [[mw:Special:MyLanguage/Wikimedia Apps/Team/Android/TrivaGame|WikiGames]], a daily trivia game based on real historical events. The release has started as an A/B test, available to 50% of users in the following languages: English, French, Portuguese, Russian, Spanish, Arabic, Chinese, and Turkish.
* The [[mw:Special:MyLanguage/Extension:Newsletter|Newsletter extension]] that is available on MediaWiki.org allows the creation of [[mw:Special:Newsletters|various newsletters]] for global users. The extension can now publish new issues as section links on an existing page, instead of requiring a new page for each issue. [https://phabricator.wikimedia.org/T393844]

'''Weekly highlight'''
* The [[mw:Special:MyLanguage/Extension:Chart|Chart extension]] is now available on all Wikimedia wikis. Editors can use this new extension to create interactive data visualizations like bar, line, area, and pie charts. Charts are designed to replace many of the uses of the legacy [[mw:Special:MyLanguage/Extension:Graph|Graph extension]].

'''Updates for editors'''
* It is now easier to configure automatic citations for your wiki within the visual editor's [[mw:Special:MyLanguage/Citoid/Enabling Citoid on your wiki|citation generator]]. Administrators can now set a default template by using the &lt;code dir=ltr&gt;_default&lt;/code&gt; key in the local &lt;bdi lang=&quot;en&quot; dir=&quot;ltr&quot;&gt;[[MediaWiki:Citoid-template-type-map.json]]&lt;/bdi&gt; page ([[mw:Special:Diff/6969653/7646386|example diff]]). Setting this default will also help to future-proof your existing configurations when [[phab:T347823|new item types]] are added in the future. You can still set templates for individual item types as they will be preferred to the default template. [https://phabricator.wikimedia.org/T384709]

* Starting the week of June 2, bots logging in using &lt;code dir=ltr&gt;action=login&lt;/code&gt; or &lt;code dir=ltr&gt;action=clientlogin&lt;/code&gt; will fail more often. This is because of stronger protections against suspicious logins. Bots using [[mw:Special:MyLanguage/Manual:Bot passwords|bot passwords]] or using a loginless authentication method such as [[mw:Special:MyLanguage/OAuth/Owner-only consumers|OAuth]] are not affected. If your bot is not using one of those, you should update it; using &lt;code dir=ltr&gt;action=login&lt;/code&gt; without a bot password was deprecated [[listarchive:list/wikitech-l@lists.wikimedia.org/message/3EEMN7VQX5G7WMQI5K2GP5JC2336DPTD/|in 2016]]. For most bots, this only requires changing what password the bot uses. [https://phabricator.wikimedia.org/T395205]
* From this week, Wikimedia wikis will allow ES2017 features in JavaScript code for official code, gadgets, and user scripts. The most visible feature of ES2017 is &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;async&lt;/code&gt;/&lt;code&gt;await&lt;/code&gt;&lt;/bdi&gt; syntax, allowing for easier-to-read code. Until this week, the platform only allowed up to ES2016, and a few months before that, up to ES2015. [https://phabricator.wikimedia.org/T381537]

* The [[mw:Special:MyLanguage/Trust and Safety Product|Trust and Safety Product team]] is finalizing work needed to roll out [[mw:Special:MyLanguage/Trust and Safety Product/Temporary Accounts|temporary accounts]] on large Wikipedias later this month. The team has worked with stewards and other users with extended rights to predict and address many use cases that may arise on larger wikis, so that community members can continue to effectively moderate and patrol temporary accounts. This will be the second of three phases of deployment – the last one will take place in September at the earliest.

This feature was requested by stewards. [https://phabricator.wikimedia.org/T386492]
* This week, the Moderator Tools and Machine Learning teams will continue the rollout of [[mw:Special:MyLanguage/2025 RecentChanges Language Agnostic Revert Risk Filtering|a new filter to Recent Changes]], releasing it to several more Wikipedias. This filter utilizes the Revert Risk model, which was created by the Research team, to highlight edits that are likely to be reverted and help Recent Changes patrollers identify potentially problematic contributions. The feature will be rolled out to the following Wikipedias: {{int:project-localized-name-afwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-bewiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-bnwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-cywiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-hawwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-iswiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-kkwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-simplewiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-trwiki/en}}.

'''Weekly highlight'''
* This week, the Moderator Tools and Machine Learning teams will continue the rollout of [[mw:Special:MyLanguage/2025 RecentChanges Language Agnostic Revert Risk Filtering|a new filter to Recent Changes]], releasing it to the third and last batch of Wikipedias. This filter utilizes the Revert Risk model, which was created by the Research team, to highlight edits that are likely to be reverted and help Recent Changes patrollers identify potentially problematic contributions. The feature will be rolled out to the following Wikipedias: {{int:project-localized-name-azwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-lawiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-mkwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-mlwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-mrwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-nnwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-pawiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-swwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-tewiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-tlwiki/en}}. The rollout will continue in the coming weeks to include [[mw:Special:MyLanguage/2025 RecentChanges Language Agnostic Revert Risk Filtering|the rest of the Wikipedias in this project]]. [https://phabricator.wikimedia.org/T391964]

'''Updates for editors'''
* Last week, [[mw:Special:MyLanguage/Trust and Safety Product/Temporary Accounts|temporary accounts]] were rolled out on Czech, Korean, and Turkish Wikipedias. This and next week, deployments on larger Wikipedias will follow. [[mw:Talk:Trust and Safety Product/Temporary Accounts|Share your thoughts]] about the project. [https://phabricator.wikimedia.org/T340001]
* Later this week, the Editing team will release [[mw:Special:MyLanguage/Help:Edit check#Multi check|Multi Check]] to all Wikipedias (except English Wikipedia). This feature shows multiple [[mw:Special:MyLanguage/Help:Edit check#Reference check|Reference checks]] within the editing experience. This encourages users to add citations when they add multiple new paragraphs to a Wikipedia article. This feature was previously available as an A/B test. [https://analytics.wikimedia.org/published/reports/editing/multi_check_ab_test_report_final.html#summary-of-results The test shows] that users who are shown multiple checks are 1.3 times more likely to add a reference to their edit, and their edit is less likely to be reverted (-34.7%). [https://phabricator.wikimedia.org/T395519]
* A few pages need to be renamed due to software updates and to match more recent Unicode standards. All of these changes are related to title-casing changes. Approximately 71 pages and 3 files will be renamed, across 15 wikis; the complete list is in [[phab:T396903|the task]]. The developers will rename these pages next week, and they will fix redirects and embedded file links a few minutes later via a system settings update.
* [[File:Octicons-sync.svg|12px|link=|class=skin-invert|Recurrent item]] View all {{formatnum:24}} community-submitted {{PLURAL:24|task|tasks}} that were [[m:Special:MyLanguage/Tech/News/Recently resolved community tasks|resolved last week]]. For example, a bug was fixed that had caused pages to scroll upwards when text near the top was selected. [https://phabricator.wikimedia.org/T364023]

'''Updates for technical contributors'''
* Editors can now use Lua modules to filter and transform tabular data for use with [[mw:Special:MyLanguage/Extension:Chart|Extension:Chart]]. This can be used for things like selecting a subset of rows or columns from the source data, converting between units, statistical processing, and many other useful transformations. [[mw:Special:MyLanguage/Extension:Chart/Transforms|Information on how to use transforms is available]]. [https://www.mediawiki.org/wiki/Special:MyLanguage/Extension:Chart/Project/Updates]
* The &lt;code dir=ltr&gt;all_links&lt;/code&gt; variable in [[Special:AbuseFilter|AbuseFilter]] is now renamed to &lt;code dir=ltr&gt;new_links&lt;/code&gt; for consistency with other variables. Old usages will still continue to work. [https://phabricator.wikimedia.org/T391811]
* [[File:Octicons-sync.svg|12px|link=|class=skin-invert|Recurrent item]] Detailed code updates later this week: [[mw:MediaWiki 1.45/wmf.7|MediaWiki]]

Latest '''[[m:Special:MyLanguage/Tech/News|tech news]]''' from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. [[m:Special:MyLanguage/Tech/News/2025/32|Translations]] are available.

'''Updates for editors'''
* Editors can now enable the [[mw:Special:MyLanguage/Product Safety and Integrity/Anti-abuse signals/User Info|User Info card]]. This feature adds an icon next to usernames on history pages and similar user-contribution log pages. When you tap or click on the icon, it displays data related to that user account such as the number of edits, reverted edits, blocks, and more. It's part of a broader project to make it easier for moderators to evaluate account trustworthiness. The feature can be enabled in [[testwiki:Special:GlobalPreferences#mw-prefsection-rendering|your global preferences]], and later this week it will be available in local preferences. [https://phabricator.wikimedia.org/T386439]
* Everybody is invited to share comments on [[m:Special:MyLanguage/CampaignEvents/Collaborative contributions|Collaborative Contributions]], a project recently launched by the [[m:Special:MyLanguage/Connection Team|Connection team]]. The project aims to create a new way to display the impact of collaborative editing activities (such as edit-a-thons, backlog drives, and WikiProjects) on the wikis. Post your comments on the [[m:Talk:CampaignEvents/Collaborative contributions|project talk page]]. [https://phabricator.wikimedia.org/T378035]
* Administrators can now define the default block duration for temporary accounts. To do that, they need to create a page named &lt;code dir=ltr&gt;MediaWiki:Ipb-default-expiry-temporary-account&lt;/code&gt; and use a value defined in &lt;code dir=ltr&gt;MediaWiki:Ipboptions&lt;/code&gt;. This allows administrators to easily block temporary accounts for 90 days, which is functionally equivalent to an indefinite block. The advantage of this solution is that it does not clutter Special:BlockList. [[mw:Special:MyLanguage/Manual:Block and unblock#Default block duration options|More documentation]] is available. [https://phabricator.wikimedia.org/T398626]
* [[File:Octicons-sync.svg|12px|link=|class=skin-invert|Recurrent item]] View all {{formatnum:27}} community-submitted {{PLURAL:27|task|tasks}} that were [[m:Special:MyLanguage/Tech/News/Recently resolved community tasks|resolved last week]].

'''Updates for technical contributors'''
* Gadgets can now include &lt;code dir=ltr&gt;.vue&lt;/code&gt; files. This makes it easier to develop modern user interfaces using [[mw:Vue.js|Vue.js]], in particular using [[mw:Special:MyLanguage/Codex|Codex]], the official design system of Wikimedia. [[wmdoc:codex/latest/icons/overview.html|Codex icons]] can be loaded through the gadget definition. [[mw:Special:MyLanguage/Extension:Gadgets#Pages|The documentation]] has examples. For user scripts that use Vue.js, an [[mw:API:CodexIcons|API module]] now exists to load Codex icons. [https://phabricator.wikimedia.org/T340460][https://phabricator.wikimedia.org/T311099]
* Module developers can now use a [[mw:Help:Extension:Translate/Message Bundles/Lua reference|Lua interface]] to simplify the preparation of Lua modules for translation on Meta-Wiki. This improvement makes it easier for translators to find and edit module strings without dealing with raw Lua code. It helps prevent mistakes that could break the module during translation. Module developers and translators are invited to [[commons:File:Translatable modules video demo July 2025.webm|watch the demo video]], read more about [[mw:Special:MyLanguage/Translatable modules|translatable modules]] to understand how it works, refer to Meta-Wiki's [[m:Module:User Wikimedia project|Module:User Wikimedia project]] for example usage, and [[mw:Talk:Translatable modules|share their feedback]] on how well it addresses the challenges in their workflow. The interface still has some performance issues, so it should not be used in widely used modules yet. [https://phabricator.wikimedia.org/T359918]
* Developers of external tools that connect to Wikimedia pages must set a user-agent that complies with [[foundation:Special:MyLanguage/Policy:Wikimedia Foundation User-Agent Policy|the user-agent policy]]. This policy will start to be more strongly enforced in August because of external crawlers that are [[diffblog:2025/04/01/how-crawlers-impact-the-operations-of-the-wikimedia-projects/|overusing]] Wikimedia's resources. Tools that are hosted on Wikimedia's Toolforge or Cloud VPS will not be affected by this for now, but should still set a user-agent. [[phab:T400119|More technical details are available]], and related questions are welcome in that task.
* Parsoid Read Views is going to be rolling out to some smaller Wikipedias over the next few weeks, following the successful transition of Wikivoyages and Wiktionaries to Parsoid Read Views. For more information, see the [[mw:Special:MyLanguage/Parsoid/Parser Unification|Parsoid/Parser Unification]] project page. [https://phabricator.wikimedia.org/project/profile/7694/]

'''Updates for editors'''
* The WikiEditor toolbar now includes [[mw:Special:MyLanguage/Help:Extension:WikiEditor#Keyboard shortcuts|its keyboard shortcuts]] in the tooltips for its buttons. This will help to improve the discoverability of this feature. [https://phabricator.wikimedia.org/T400583]
* The [[m:Special:MyLanguage/Product and Technology Advisory Council|Product and Technology Advisory Council]] published a set of [[m:Special:MyLanguage/Product and Technology Advisory Council/August 2025 draft PTAC proposals for feedback|proposed experiments]] the Wikimedia Foundation can try to improve communication with community. Feedback on the proposals are welcomed until August 22 on [[m:Talk:Product and Technology Advisory Council/August 2025 draft PTAC proposals for feedback|this talk page]].
* The search bar on the Minerva skin (mobile) has been updated to use the same type-ahead search component that is used on the Vector 2022 skin. There are no changes in search functionality but there are minor visual changes. Specifically, the close-search button has been changed from an &quot;X&quot; to a back arrow. This helps to distinguish it from the other &quot;X&quot; button that is used to clear any text. [https://phabricator.wikimedia.org/T393944]
* Editors on some wikis will see a new toggle for &quot;Group results by page&quot; on watchlist, related changes, and recent changes pages. This is [[mw:Special:MyLanguage/Moderator Tools/Watchlist/Experiment|an A/B experiment]] that is planned to start on August 11, and will run for 3–6 weeks on the Bengali, Chinese, Czech, French, Greek, Portuguese, and Urdu Wikipedias. The experiment will examine how making this feature more discoverable might affect editors' ability to find the edits they are looking for. [https://phabricator.wikimedia.org/T396789]
* [[File:Octicons-sync.svg|12px|link=|class=skin-invert|Recurrent item]] View all {{formatnum:31}} community-submitted {{PLURAL:31|task|tasks}} that were [[m:Special:MyLanguage/Tech/News/Recently resolved community tasks|resolved last week]].

'''Updates for technical contributors'''
* The multiwiki datasets of [[:wikt:en:Module:Unicode data|Unicode data]] have been moved to [[c:Category:Unicode Module Datasets|Category:Unicode Module Datasets]] on Wikimedia Commons, to follow the idea of &quot;One common data source, multiple local wikis&quot;. Most wikis have been updated to use the Commons version. You can ask questions at [[c:Category talk:Unicode Module Datasets|the talkpage]]. [https://en.wiktionary.org/wiki/Module_talk:Unicode_data#Data_from_commons]
* Lua code can add warnings when something is wrong, by using the &lt;code dir=ltr&gt;mw.addWarning()&lt;/code&gt; function. It is now possible to add more than one warning, instead of new warnings replacing old ones. If you maintain a Lua module that used warnings, you should check it still works as expected.

* An A/A test to measure the baseline for reader retention was launched 12 August using [[wikitech:Experimentation Lab|Experimentation Lab]]. This measures the percentage of users who revisit a wiki after their initial visit over a 14-day period. No visual changes are expected. The experiment will run through 31 August.

'''Updates for editors'''
* [[File:Octicons-gift.svg|12px|link=|class=skin-invert|Wishlist item]] [[File:Octicons-tools.svg|12px|link=|class=skin-invert|Advanced item]] Template authors can now use additional CSS properties, since the CSS sanitizer used by [[mw:Special:MyLanguage/Help:TemplateStyles|TemplateStyles]] was updated. For example: &lt;code&gt;width: fit-content&lt;/code&gt;; &lt;code&gt;ruby-align&lt;/code&gt;; relative units such as &lt;code&gt;lh&lt;/code&gt;; and custom strings in &lt;code&gt;list-style-type&lt;/code&gt;.

* On large wikis, the default time period to display edits from, within the Special:RecentChanges page, has been changed from 7 days to 1 day. This is part of a performance improvement project. This should have no user-facing impact due to the quantity of edits on these wikis. [https://phabricator.wikimedia.org/T399455]
* Administrators can now access the [[{{#special:BlockedExternalDomains}}]] page from the [[{{#special:CommunityConfiguration}}]] list page. This makes it easier to find. [https://phabricator.wikimedia.org/T393240]
* Wikimedia Commons videos were not shown in the Videos tab in Google Search. The problem was investigated and reported to Google who have now fixed the issue.

Queries to these older fields will start to fail starting this week and developers should use &lt;code&gt;rc_source&lt;/code&gt; instead. These older fields were deprecated over 10 years ago and should not be in use. This is part of work to improve the performance and stability of queries to the recentchanges table.

'''In depth'''
* The latest quarterly [[mw:Special:MyLanguage/Wikimedia Language and Product Localization/Newsletter/2025/July|Language and Internationalization Newsletter]] is now available. This edition includes: support for new languages in MediaWiki and translatewiki; the start of the Language Onboarding and Development project to help support the growth of new and small wikis; updates on research projects; and more.

'''Meetings and events'''
* The next [[mw:Special:MyLanguage/Wikimedia Language and Product Localization/Community meetings#29 August 2025|Language Community Meeting]] is happening soon, August 29th at [https://zonestamp.toolforge.org/1756479600 15:00 UTC]. This week's meeting will cover: the Avro keyboard developers from Wikimedia Bangladesh, who were recently awarded a national award for their contributions to this keyboard; and other topics.

'''Weekly highlight'''
* The Editing team wants to compile a list of templates, jargon terms, and policies used in edit summaries when a copyright violation is removed. This will help them identify the number of edits reverted due to copyright issues. We invite community members from the following Wikis to list these terms in [[Phab:T402601|T402601]], or to share their list with [[User:Trizek (WMF)|Trizek_(WMF)]]: {{int:project-localized-name-arwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-cswiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-dewiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-enwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-eswiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-fawiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-frwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-hewiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-idwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-itwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-jawiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-kowiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-nlwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-plwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-ptwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-trwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-ukwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-viwiki/en}}{{int:comma-separator/en}}{{int:project-localized-name-zhwiki/en}}.

'''Updates for editors'''
* The [[mw:Special:MyLanguage/Help:Extension:CampaignEvents|CampaignEvents extension]] has been enabled for all Wikisources. The extension makes it easier to organize and participate in collaborative activities, like edit-a-thons and WikiProjects, on the wikis. The extension has three features: [[m:Special:MyLanguage/Event Center/Registration|Event Registration]], [[m:Special:MyLanguage/CampaignEvents/Collaboration list|Collaboration List]], and [[m:Special:MyLanguage/Connection Team/Invitation list|Invitation List]]. To request the extension for your wiki, visit the Deployment information page.

* Upon clicking an empty search bar, logged-out users will see suggestions of articles for further reading on English Wikipedia beginning the week of September 22. The feature will be available on both desktop and mobile. All non-English wikis received this change in June and July. The goal is to make it easier for users to find articles.

* Wikifunctions now has a new capability called &quot;lightweight enumeration types&quot;, an enumeration type is simply a fixed set of values that's in the type's definition. This capability makes it quick and easy to define such a type, and allows for the reuse of values that are already present in Wikidata. Here is [[f:Special:MyLanguage/Wikifunctions:Status updates/2025-07-19|a newsletter]] to learn more.
* The latest [[mw:Special:MyLanguage/Readers/Newsletter updates#August 2025: Newsletter #1|Readers Newsletter]] is now available. This edition includes: the formation of two new teams — Reader Growth and Reader Experience; insights into declining pageviews and account creations; highlights from the Wikimania Nairobi panel on improving the reading experience; upcoming experiments to engage new and existing readers; and more.

'''Weekly highlight'''
* The Editing team is working on a new check: [[mw:Special:MyLanguage/Paste check|Paste check]]. This check informs newcomers who paste text into Wikipedia that the content might not be accepted. This check is an effort to increase the likelihood that the new content people are adding to Wikipedia is aligned with the Movement's commitment to offering information under a free content license. This check will soon be tested at a few wikis. If your community is interested in this test, please [[phab:T403680|tell us in this task]], or [[mw:Talk:Edit check|contact the team]].

'''Updates for editors'''
* [[File:Octicons-tools.svg|12px|link=|class=skin-invert|Advanced item]] Later this week, users of the &quot;{{int:codemirror-beta-feature-title}}&quot; [[Special:Preferences#mw-prefsection-betafeatures|beta feature]] will be able to use a [[w:en:Lint (software)|linting tool]] to see errors or other potential problems in wikitext in real time. See the [[mw:Special:MyLanguage/Help:Extension:CodeMirror#Linting|help page for more information]]. [https://phabricator.wikimedia.org/T381577]
* [[File:Octicons-tools.svg|12px|link=|class=skin-invert|Advanced item]] When browsing a wiki (like &lt;code dir=ltr&gt;en.wikipedia.org&lt;/code&gt;), the software responds in one of two ways: a desktop page, or a redirect to a mobile version on an &quot;m&quot; domain (like &lt;code dir=ltr&gt;en.m.wikipedia.org&lt;/code&gt;). Over the next three weeks, MediaWiki will start displaying the mobile version to mobile devices directly on the standard domain, without this redirect. This change does not affect existing m-dot URLs, or the &quot;Desktop view&quot; opt-out. [[mw:Requests for comment/Mobile domain sunsetting/2025 Announcement|Learn more]]. [https://phabricator.wikimedia.org/T214998]
* When an edit changes the categories of a page, the changes to the category membership counts are now happening asynchronously. This improves the speed of saving edits, especially when moving many pages to or from the same category, and reduces the risk of site outages, but it means that the counts can show outdated information for a few minutes. [https://phabricator.wikimedia.org/T365303] 
* Edits on Wikidata to qualifiers (properties and values) and references (properties and values) in a Wikidata item statement will now not add entries to the RecentChanges or Watchlist pages on all other Wikis. This is a temporary change to improve performance while other solutions are created. Wikidata's own pages remain unchanged.

* [[m:Special:MyLanguage/Tech/Server switch|All wikis will be read-only]] for a few minutes on September 24. This is planned at [https://zonestamp.toolforge.org/1758726000 15:00 UTC].

* Edits to Wikidata aliases (an alternative name for an item or a property) will now be shown in RecentChanges and Watchlist entries on other wikis less often, reducing unnecessary notifications. This will reduce the overall quantity of 'noisy' entries. Wikidata's own pages remain unchanged. [[m:Wikidata For Wikimedia Projects/Reduce change propagation noise#Phase 1: More granular Alias tracking|Learn more]]. [https://phabricator.wikimedia.org/T401288]
* The new [https://www.unicode.org/versions/Unicode17.0.0/ Unicode 17.0] version has been released. The [[:c:Category:Unicode Module Datasets|datasets on Commons]] for the [[:d:Q39301585|Module:Unicode data]] have been updated. Wikipedias that do not use the Commons datasets should either update their own data or switch to the Commons datasets.
* Users of the [[m:Special:MyLanguage/Wikimedia Enterprise|Wikimedia Enterprise]] Structured Contents endpoints can now access [https://enterprise.wikimedia.com/blog/parsed-wikipedia-tables/ Parsed Tables]. The new Parsed Tables feature extracts and represents Wikipedia tables in structured JSON. This improves machine accessibility as part of the [https://enterprise.wikimedia.com/api/structured-contents/ Structured Contents initiative].

'''Weekly highlight'''
* [https://zonestamp.toolforge.org/1758726000 On September 24th at 15:00 UTC], all Wikimedia sites users will experience a brief read-only period due to a scheduled [[m:Special:MyLanguage/Tech/Server switch|datacenter server switchover]]. The Wikimedia Foundation's Site Reliability Engineering (SRE) team will redirect all traffic from one primary server to its backup. You can listen to the switchover using the [http://listen.hatnote.com/ &quot;Listen to Wikipedia&quot;] tool, where you will hear edits stop for a few minutes during the read-only phase, then resume. This twice-yearly datacenter server switchover ensures reliability by testing the backup datacenter, so that our sites can stay online even if the primary datacenter fails. You can [[diffblog:2025/03/12/hear-that-the-wikis-go-silent-twice-a-year/|read more about the process on the Diff blog]].

'''Updates for editors'''
* Editors of [[f:Special:Mylanguage/Wikifunctions:Status updates/2025-09-12#Next round of Wiktionaries to receive embedded Wikifunctions calls|60 more Wiktionaries]] will soon be able to call [[f:Special:MyLanguage/Wikifunctions:Introduction|functions from Wikifunctions]] and integrate them into their pages. A function takes one or more inputs and transforms them into a desired output, like adding numbers, converting miles to meters, calculating elapsed time, or declining a word into a case. They will join the other [[f:Special:MyLanguage/Wikifunctions:Status updates/2025-08-29#Wikifunctions available on 65 Wiktionaries|65 Wiktionary language editions]], which already have access to embedded Wikifunctions calls. Later this year, plans are in place to expand to more Wiktionaries and the Incubator.
* A new [[mw:Special:MyLanguage/Help:Magic words#Technical metadata of another page|parser function]] has been added: &lt;code&gt;&lt;nowiki&gt;{{#contentmodel}}&lt;/nowiki&gt;&lt;/code&gt;. Template editors and admins can use it to get the localized or canonical name of the [[mw:Special:MyLanguage/Help:ChangeContentModel|content model]] of a specific page. The function makes it easier to create and edit system messages, such as ''MediaWiki:editinginterface'', even when you switch types of pages, like wiki, JavaScript, CSS or JSON page. [https://phabricator.wikimedia.org/T328254]
* Adding or editing a &lt;code&gt;DISPLAYTITLE&lt;/code&gt; for an article using VisualEditor will no longer be broken. Editors who use VisualEditor mode to modify the &lt;code&gt;&lt;nowiki&gt;{{DISPLAYTITLE}}&lt;/nowiki&gt;&lt;/code&gt; would no longer have the literal text &quot;DISPLAYTITLE&quot; or its localized variant added to their articles. A list of pages that may have been affected and might need cleanup is documented in [[phab:P83438|this ticket]]. 
* Beta users of the Wikipedia Android app can now try the redesigned [[mw:Special:MyLanguage/Wikimedia Apps/Team/Android/Activity Tab Experiment|Activity tab]], which replaces the Edits tab. The new tab offers personalized insights into reading, editing, and donation activity, while simplifying navigation and making app use more engaging.

* A major software upgrade has been made to [[phab:|Phabricator]]. The update introduces performance improvements, a refreshed search interface, enhancements to Maniphest task search, updates to user profile pages and project workboards, new Herald automation features, as well as general text input, mobile experience improvements and more. [https://phabricator.wikimedia.org/phame/post/view/321/iterative_improvements_september_2025/]

'''Updates for editors'''
* The Community Tech team will release the new Community Wishlist extension on October 1, that will improve the way wishes will be submitted. The new extension will allow users to add tags to their wishes to better categorise them, and (in a future iteration) to filter them by status, tags and focus areas. It will also be possible to support individual wishes again, as requested by the community in many instances. The old system will be retired. There will be a brief period of downtime while the extension is deployed and wishes are migrated to the new system. You can read more about this [[:m:Special:MyLanguage/Community Wishlist/Updates|in the latest update]] or you can consult the [[:mw:Special:MyLanguage/Help:Extension:CommunityRequests|current documentation on MediaWiki]].
* As announced [[diffblog:2025/09/02/better-detecting-bots-and-replacing-our-captcha/|on Diff blog]], the production trial of the [[mw:Special:MyLanguage/Product Safety and Integrity/Anti-abuse signals/hCaptcha|hCaptcha]] service for bot detection has begun. The trial is currently using hCaptcha to protect account creation on Chinese, Persian, Portuguese, Indonesian, Japanese, and Turkish Wikipedias, where it will replace our existing [[mw:Special:MyLanguage/Extension:ConfirmEdit#FancyCaptcha|CAPTCHA]] (FancyCaptcha). The goal with the trial is to better block bots while also improving usability and accessibility for users who encounter CAPTCHA challenges.
* The [[mw:Special:MyLanguage/Extension:CampaignEvents|CampaignEvents]] extension has been [[m:Special:MyLanguage/CampaignEvents/Deployment status|deployed]] to Wikimedia Commons. The extension makes it easier to organize and participate in collaborative activities, like edit-a-thons and WikiProjects, on the wikis. On Commons, anyone who is a registered user can use it as an event participant. To use it as an organizer, someone needs to have the [[c:Special:MyLanguage/Commons:Event organizers|event organizer right]].
* [[:m:Special:MyLanguage/WMDE Technical Wishes/Sub-referencing|Sub-referencing]], a new feature to re-use references with different details has been released to German Wikipedia. You can [[:m:Special:MyLanguage/WMDE Technical Wishes/Sub-referencing#test|test the feature]] on testwiki or [https://en.wikipedia.beta.wmcloud.org/wiki/Sub-referencing on betawiki] as well. Please share your thoughts on [[:m:Talk:WMDE Technical Wishes/Sub-referencing#Templates used in sub-references|using templates in sub-references]] or [[:m:Talk:WMDE Technical Wishes/Sub-referencing#Pilot wikis|volunteer to become a pilot wiki]].
* On wikis using the [[mw:Special:MyLanguage/Help:Growth/Mentorship|Mentorship]] system, communities can now opt experienced editors out of Mentorship through [[{{#special:CommunityConfiguration/Mentorship}}]]. Within this setting, communities may define thresholds, based on edit count and account age, to decide when an editor is considered experienced enough to no longer receive Mentorship. [https://phabricator.wikimedia.org/T403563]
* The Editing Team and the Machine Learning Team are working on a new check for newcomers: [[mw:Special:MyLanguage/Edit check/Tone Check|Tone check]]. Using a prediction model, this check will encourage editors to improve the tone of their edits, using artificial intelligence. We invite volunteers to review the first version of the Tone language model for the following languages: Arabic, Czech, German, Hebrew, Indonesian, Dutch, Polish, Russian, Turkish, Chinese, Farsi, Italian, Norwegian, Romanian and Latvian. Users from these wikis interested in reviewing this model are [[mw:Special:MyLanguage/Edit_check/Tone_Check/Model_evaluation|invited to sign up at MediaWiki.org]]. The deadline to sign up is on October 3, which will be the start date of the test.
* The rollout of [[:mw:Special:MyLanguage/Help:Manage blocks|multiblocks]] had the side effect that non-active block logs may have been shown on {{#special:Contributions}} and on blocked users' user and user_talk pages. This issue will be fully resolved in a few days. As part of the fix, [{{fullurl:Special:Allmessages|prefix=sp-contributions-blocked-notice}} messages prefixed with &lt;code&gt;sp-contributions-blocked-notice&lt;/code&gt;] will be removed and replaced with [{{fullurl:Special:Allmessages|prefix=blocked-notice-logextract}} those prefixed with &lt;code&gt;blocked-notice-logextract&lt;/code&gt;] in a few weeks. Please help translate the new messages and update any local overrides if needed.
* There was a bug with links added using visual editor if they included characters such as &lt;code dir=ltr&gt;&lt;nowiki&gt;[ ] |&lt;/nowiki&gt;&lt;/code&gt; after the fragment identifier (&lt;code&gt;&lt;nowiki&gt;#&lt;/nowiki&gt;&lt;/code&gt;). They were not encoded properly creating an incorrect link. This has been fixed. [https://phabricator.wikimedia.org/T404823]
* One new wiki has been created: a {{int:project-localized-name-group-wikiquote/en}} in [[d:Q9237|Malay]] ([[q:ms:|&lt;code&gt;q:ms:&lt;/code&gt;]]) [https://phabricator.wikimedia.org/T404698]

'''Updates for technical contributors'''
* Later this week, editors using Lua modules will be able to use the &lt;code&gt;[[mw:Special:MyLanguage/Extension:Scribunto/Lua reference manual#mw.title.newBatch|mw.title.newBatch]]&lt;/code&gt; function to look up the existence of up to 25 pages at once, in a way that only increases the [[mw:Special:MyLanguage/Manual:Parser functions#Expensive parser functions|expensive function]] count once.
* A new [[m:Special:MyLanguage/Product and Technology Advisory Council/Unsupported Tools Working Group|Unsupported Tools Working Group]] has been formed as part of ongoing efforts to collectively determine technical work priorities, similar to the [[m:Special:MyLanguage/Product and Technology Advisory Council|Product &amp; Technology Advisory Council]] (PTAC). The working group will help prioritize and review requests for support of unmaintained extensions, gadgets, bots, and tools. For the first cycle, the group will be prioritizing an unsupported Wikimedia Commons tool.

'''Weekly highlight'''
* [[mw:Special:MyLanguage/Help:Edit check#paste|Paste Check]] is a new Edit Check feature to help avoid and fight copyright violations. When editors paste text into an article, Paste Check prompts them to confirm the origin and licensing of the content. Starting Wednesday, 8 October, [[phab:T403680|22 wikis will test Paste Check]]. Paste Check will help new volunteers understand and follow the policies and guidelines necessary to make constructive contributions to Wikipedia projects.
'''Updates for editors'''
* Mobile devices will receive mobile articles directly on the standard domain (like &lt;code&gt;en.wikipedia.org&lt;/code&gt;), instead of via a redirect to an &quot;m&quot; domain (like &lt;code&gt;en.m.wikipedia.org&lt;/code&gt;). This change improves performance. This week it will be enabled on Wikipedias. The existing mobile URLs and the &quot;Desktop view&quot; opt-out remain available. [[mw:Requests for comment/Mobile domain sunsetting/2025 Announcement|Learn more]]. [https://phabricator.wikimedia.org/T214998]
* New [[mw:Special:MyLanguage/Help:CirrusSearch#creationdate and lasteditdate|date filters]], &lt;code dir=ltr&gt;creationdate:&lt;/code&gt; and &lt;code dir=ltr&gt;lasteditdate:&lt;/code&gt;, are now available in the wiki search engine. This allows users to filter search results by a page's first or last revision date. The filters support comparison operators (e.g. &lt;code dir=ltr&gt;&gt;2024&lt;/code&gt;) and relative dates (e.g. &lt;code dir=ltr&gt;today-1d&lt;/code&gt;), making it easier to find recently updated content or pages within specific age ranges. [https://phabricator.wikimedia.org/T403593]
* [[f:|Wikifunctions]] now supports rich text in embedded calls across the 150 wikis where it's enabled. To showcase this, the team created a [[f:Z26333|Latin declination table]] that Wiktionary editors can use to automatically generate noun forms, producing clear, formatted results — see an [[f:Wikifunctions:Embedded function calls/Wiktionary tables demonstration|example output]]. If you need any help or have any feedback, please [[f:Wikifunctions:Project chat|contact the Wikifunctions Team]]. [https://phabricator.wikimedia.org/T397402]

'''Updates for technical contributors'''
* The field &lt;code dir=ltr&gt;rev_sha1&lt;/code&gt; in the revision database table is being removed in favor of &lt;code dir=ltr&gt;content_sha1&lt;/code&gt; in the content database table. See [https://lists.wikimedia.org/hyperkitty/list/cloud@lists.wikimedia.org/thread/2D2M3SP4WHR6BXXKTZ2PBLZQYR3EGQVR/ the announcement] for more information.
* The [[mw:Special:MyLanguage/Reading/Web|Reader Experience team]] will roll out [[w:en:Light-on-dark color scheme|Dark Mode]] user interface on all Wikimedia sites on October 29, 2025. All anonymous users of Wikimedia sites will have the option to activate a color scheme that features light-colored text on a dark background. This is designed to provide a more comfortable reading experience, especially in low-light situations. Template authors and technical contributors are encouraged to [[mw:Special:MyLanguage/Reading/Web/Accessibility for reading/Updates/2024-04|learn how to make pages ready for Dark mode]] and address any compatibility issues found in templates in their wiki before the enablement. Please contact the Web team for questions or any support on [[mw:Talk:Reading/Web/Accessibility for reading#|this talk page]] before the enablement. [https://phabricator.wikimedia.org/T395628]
* Starting on Monday, October 6, API endpoints under the &lt;code&gt;rest.php&lt;/code&gt; path will be rerouted through a new internal API Gateway. Individual wikis will be updated based on the standard release groups, with total traffic increased over time. This change is expected to be non-breaking and non-disruptive.

'''Weekly highlight'''
* Last week, improvements to account security and two-factor authentication (2FA) features were enabled across all wikis. These changes include user interface improvements for [https://auth.wikimedia.org/metawiki/wiki/Special:AccountSecurity Special:AccountSecurity], the support of multiple 2FA methods via authenticator apps and portable security keys (previously users could only enable one method), and a new Recovery Codes module which facilitates fewer account lockouts due to lost two-factor apps and devices. As part of the [[mw:Special:MyLanguage/Product Safety and Integrity/Account Security|Account Security]] project, work is continuing through the rest of 2025 on further user experience improvements, and support for passkeys as an alternate second factor. 

'''Updates for editors'''

* Another part of the Account security project is making 2FA generally available to all users. Along with editors with advanced privileges, such as administrators and bureaucrats, 40% of editors now have access to 2FA. You can check if you have access at [https://auth.wikimedia.org/metawiki/wiki/Special:AccountSecurity Special:AccountSecurity]. Instructions for activation are on the linked page. The plan is to continue increasing availability if it is determined that the user support capabilities are able to support global usage. [https://phabricator.wikimedia.org/T400579]
* This week, users at wikis where talk page [[mw:Special:MyLanguage/Talk pages project/Usability|Usability Improvements]] are already available by default (everywhere ''except'' the 12 wikis listed in [[phab:T379264|T379264]]) will gain the ability to Thank a comment directly from the talk page it appears on. Before this change, Thanking could only be done by visiting the revision history of the talk page. You can [[diffblog:2025/10/13/revolutionizing-gratitude-a-new-era-of-thanking-comments/|learn more about this change]]. [https://phabricator.wikimedia.org/T366095]
* Users who have not [[Special:Preferences#mw-prefsection-personal-email|verified their email address]] will soon be receiving monthly Notification reminders to do so. This is because users who have verified their email can more easily recover their account. These reminders will not be sent if the user is inactive or removes the unverified email from their account.

* To optimize how user data is stored in our databases, the saved preferences of users who haven't logged in for over five years and have fewer than 100 edits will be cleared. When those users return, default settings will apply. [https://phabricator.wikimedia.org/T406724]

'''Updates for editors'''
* The Wikipedia iOS app has launched an A/B/C test of improvements made to the tabbed browsing feature for select regions and languages. The test, named “More dynamic tabs”, explores new tab experiences and includes “Did you know” and “Because you read” article recommendations. You can [[mw:Special:MyLanguage/Wikimedia Apps/Team/iOS/Tabbed Browsing (Tabs)/New Tab Experience and Recommendations Experiment|read more on the project page]].
* Autoconfirmed users on [[gitiles:operations/mediawiki-config/+/a2d2aaab9ace84280dd2f4c70a33bb69cd73850f/dblists/small.dblist|small]] and [[gitiles:operations/mediawiki-config/+/a2d2aaab9ace84280dd2f4c70a33bb69cd73850f/dblists/medium.dblist|medium wikis]] with the CampaignEvents extension can now use [[m:Special:MyLanguage/Event Center/Registration|Event Registration]] without the Event Organizer right. This feature lets organizers enable registration, manage participants, and lets users register with one click instead of signing event pages.

For example, the issue of flashing colors when holding or pressing the arrow keys under the dark mode settings in Vector 2022 has been fixed. [https://phabricator.wikimedia.org/T402285]

'''Updates for technical contributors'''

* The CampaignEvents extension will be deployed to all remaining wikis during the week of 17 November 2025. The extension currently includes three features: Event Registration, Collaboration List, and Invitation List. For this rollout, Invitation List will not be enabled on Wikifunctions and MediaWiki unless requested by those communities. [[m:Special:MyLanguage/CampaignEvents/Deployment status|Visit the deployment page to learn more]].
* The SwaggerUI-based REST sandbox experience is now live on all wiki projects. The sandbox can be accessed through the [[{{#special:RestSandbox}}]] page. Please report any issues to the MediaWiki Interfaces team board, or join the discussion on the [[mw:Special:MyLanguage/MediaWiki Interfaces Team/Feature Feedback/REST Sandbox|project launch]] page. [https://phabricator.wikimedia.org/project/board/6931/]
* Transform endpoints with a trailing slash path in the MediaWiki REST API are now marked as deprecated. They will remain functional during this time, but removal is expected by the end of January 2026. All API users currently calling them are encouraged to transition to the non-trailing slash versions. Both endpoint variations can be found and tested using the [https://test.wikipedia.org/w/index.php?api=mw-extra&amp;title=Special%3ARestSandbox REST Sandbox]. See the [[mw:API/Deprecation|MediaWiki REST API Deprecation]] page for more detailed information about the API deprecation policies and procedures.
* A dedicated [[mw:API:REST API/Changelog|changelog now exists for the MediaWiki REST API]]. The changelog provides an overview of these changes, making it easier for developers to keep track of improvements and iterations. Announcements will also continue to flow through the standard communication channels, including Tech News and email distribution lists, but can now be more easily referenced from a central location. If you have feedback about the style, structure, or content of this changelog, please [[mw:API talk:REST API/Changelog|join the discussion]].
* Administrators can delete the tracking category which was previously added by the JsonConfig extension, as it is no longer used. See the categories linked from [[d:Q130635582#sitelinks-wikipedia|Q130635582]]. It is OK if there are still pages listed in the category as that is just a caching issue, and they will be automatically cleared out the next time each page is edited.

'''Updates for editors'''
* Administrators will now find that [[{{#special:MergeHistory}}]] is now significantly more flexible about what it can merge. It can now merge sections taken from the middle of the history of the source (rather than only the start) and insert revisions anywhere in the history of the destination page (rather than only the start). [https://phabricator.wikimedia.org/T382958]
* For users with &quot;{{int:discussiontools-preference-autotopicsub}}&quot; [[Special:Preferences#mw-prefsection-editing|enabled in their preferences]], starting a new topic or adding a reply to an existing topic will now subscribe them to replies to that topic. Previously, this would only happen if the DiscussionTools &quot;{{int:Skin-action-addsection}}&quot; or &quot;{{int:Discussiontools-replybutton}}&quot; widgets were used. When DiscussionTools was originally launched existing accounts were not opted in to automatic topic subscriptions, so this change should primarily affect newer accounts and users who have deliberately changed their preferences since that time. [https://phabricator.wikimedia.org/T290778]
* Scribunto modules can now be used to [[mw:Special:MyLanguage/Extension:Scribunto/Lua reference manual#SVG library|generate SVG images]]. This can be used to build charts, graphics and other visualizations dynamically through Lua, reducing the need to compose them externally and upload them as files. [https://phabricator.wikimedia.org/T405861]
* Wikimedia sites now provide all anonymous users with the option to enable a dark mode color scheme, featuring light-colored text on a dark background. This enhancement aims to deliver a more enjoyable reading experience, especially in dimly lit environments.  [https://phabricator.wikimedia.org/T395628]
* Users with large watchlists have long faced timeouts when editing [[Special:EditWatchlist|Special:EditWatchlist]]. The page now loads entries in smaller sections instead of all at once due to a paging update, allowing everyone to edit their watchlists smoothly. As part of the database update, sorting by expiry has been removed because it was over 100× slower than sorting by title. A [https://meta.wikimedia.org/wiki/Community_Wishlist/W454 community wish] has been created to explore alternative ways to restore sort-by-expiry.

'''Updates for technical contributors'''
* Since 2019 the [[m:Special:MyLanguage/Wikimedia URL Shortener|Wikimedia URL Shortener]] at https://w.wiki is available for all Wikimedia wikis to create short links to articles, permalinks, diffs, etc. It is available in the sidebar as &quot;Get shortened URL&quot;. There are 30 wikis that also install an older &quot;ShortUrl&quot; extension. The old extension will soon be removed. This means &lt;code&gt;/s/&lt;/code&gt; URLs will not be advertised under article titles via HTML &lt;code dir=ltr&gt;class=&quot;title-shortlink&quot;&lt;/code&gt;. The &lt;code&gt;/s/&lt;/code&gt; URLs will keep working. [https://phabricator.wikimedia.org/T107188]

'''In depth'''
* In 2025, the Wikimedia Foundation reported that AI systems and search engines increasingly use Wikipedia content without driving users to the site, contributing to an 8% drop in human pageviews compared to 2024. After detecting bots disguised as humans, Wikimedia updated its traffic data to reflect this shift.

'''Updates for editors'''
[[File:Talk pages default look (April 2023).jpg|thumb|alt=Screenshot of the visual improvements made on talk pages|Example of a talk page with the new design, in French.]]
* Starting November 12, users will see a change in the [[m:Special:MyLanguage/Talk pages project/Feature summary#Usability improvements|appearance of talk pages]] on [[Phab:T379264|some Wikipedias]]. Almost [[phab:T392121|all wikis]] have received this design change; [[phab:T409297|English Wikipedia]] will get these changes later. You can read more [[diffblog:2024/05/02/making-talk-pages-better-for-everyone/|on ''Diff'']]. Users can opt out of these changes [[Special:Preferences#mw-prefsection-editing|in their user preferences]] in &quot;{{int:discussiontools-preference-visualenhancements}}&quot;. [https://phabricator.wikimedia.org/T379264]
* MediaWiki can now display a [[mw:Special:MyLanguage/Help:Protection indicators|page indicator]] automatically while a page is protected. This feature is disabled by default. It can be enabled by [[m:Special:MyLanguage/Requesting wiki configuration changes|community request]]. [https://phabricator.wikimedia.org/T12347]
* Using the &quot;{{int:showpreview}}&quot; or &quot;{{int:showdiff}}&quot; buttons in the wikitext editor will now carry over certain URL parameters like '[[mw:Special:MyLanguage/Manual:Parameters to index.php#useskin|useskin]]', '[[mw:Special:MyLanguage/Manual:Parameters to index.php#uselang|uselang]]' and '[[mw:Special:MyLanguage/Help:Section#Editing sections|section]]'. This update also fixes an issue where, if the browser crashed while previewing an edit to a single section, saving this edit could overwrite the entire page with just that section’s content. [https://phabricator.wikimedia.org/T62744][https://phabricator.wikimedia.org/T24029][https://phabricator.wikimedia.org/T155097]
* Wikivoyage wikis can use [[mw:Special:MyLanguage/Help:Extension:Kartographer#Markers and counters|colored map markers in the article text]]. The text of these markers will now be shown in contrasting black or white color, instead of always being white. Local workarounds for the problem can be removed. [https://phabricator.wikimedia.org/T369454]
* The Activity tab in the Wikipedia Android app is now available for all users. The new tab offers personalized insights into reading, editing, and donation activity, while simplifying navigation and making app use more engaging. [https://www.mediawiki.org/wiki/Wikimedia_Apps/Team/Android/Activity_Tab_Experiment]
* The Reader Growth team is launching an experiment called &quot;Image browsing&quot; to test how to make it easier for readers to browse and discover images on Wikipedia articles. This experiment, a mobile-only A/B test, will go live on English Wikipedia in the week of November 17 and will run for four weeks, affecting 0.05% of users on English wiki. The test launched on November 3 on Arabic, Chinese, French, Indonesian, and Vietnamese wikis, affecting up to 10% of users on those wikis. [https://www.mediawiki.org/wiki/Readers/Reader_Growth/WE3.1.3_Image_Browsing]
* [[File:Reload icon with two arrows.svg|12px|link=|class=skin-invert|Recurrent item]] View all {{formatnum:27}} community-submitted {{PLURAL:27|task|tasks}} that were [[m:Special:MyLanguage/Tech/News/Recently resolved community tasks|resolved last week]]. For example the inability to lock accounts on mobile sites has been fixed. [https://phabricator.wikimedia.org/T256185]

'''Updates for technical contributors'''
* [[wikitech:Help talk:Toolforge/Toolforge standards committee#November 2025 committee nominations|Nominations are open on Wikitech]] for new [[wikitech:Help:Toolforge/Toolforge standards committee|Toolforge standards committee]] members. The committee oversees the Toolforge [[wikitech:Help:Toolforge/Right to fork policy|Right to fork policy]] and [[wikitech:Help:Toolforge/Abandoned tool policy|Abandoned tool policy]] among other duties. Nominations will remain open through 2025-11-28.
* The [[w:JSON Web Token#Standard fields|JWT issuer field]] in [[mw:Special:MyLanguage/OAuth/For Developers#OAuth 2|OAuth 2 access tokens]] for [[m:Special:MyLanguage/Help:Unified login|SUL wikis]] has been changed to &lt;code&gt;&lt;nowiki&gt;https://meta.wikimedia.org&lt;/nowiki&gt;&lt;/code&gt;. Old access tokens will still work. [https://phabricator.wikimedia.org/T399199]
* The [[w:JSON Web Token#Standard fields|JWT subject field]] in [[mw:Special:MyLanguage/OAuth/For Developers#OAuth 2|OAuth 2 access tokens]] will soon change from &lt;code&gt;&lt;user id&gt;&lt;/code&gt; to &lt;code dir=ltr style=&quot;white-space:nowrap&quot;&gt;mw:&lt;identity type&gt;:&lt;user id&gt;&lt;/code&gt;, where &lt;code&gt;&lt;identity type&gt;&lt;/code&gt; is typically &lt;code dir=ltr&gt;CentralAuth:&lt;/code&gt;&lt;!-- not a typo --&gt; (for [[m:Special:MyLanguage/Help:Unified login|SUL wikis]]) or &lt;code dir=ltr style=&quot;white-space:nowrap&quot;&gt;local:&lt;wiki id&gt;&lt;/code&gt; (for other wikis). This is to avoid conflicts between different user ID types, and to make OAuth 2 access tokens and the &lt;code&gt;sessionJwt&lt;/code&gt; cookie more similar. Old access tokens will still work. [https://phabricator.wikimedia.org/T399199]
* MediaWiki's block messages ([[MediaWiki:Blockedtext|blockedtext]], [[MediaWiki:Blockedtext-partial|blockedtext-partial]], [[MediaWiki:Autoblockedtext|autoblockedtext]], [[MediaWiki:Systemblockedtext|systemblockedtext]], [[MediaWiki:Blockedtext-tempuser|blockedtext-tempuser]], [[MediaWiki:Autoblockedtext-tempuser|autoblockedtext-tempuser]]) now support additional parameters indicating whether the user is blocked from editing their own user talk page &lt;code&gt;&lt;nowiki&gt;$9&lt;/nowiki&gt;&lt;/code&gt; or emailing other users &lt;code&gt;&lt;nowiki&gt;$&lt;/nowiki&gt;&lt;nowiki&gt;10&lt;/nowiki&gt;&lt;/code&gt;. [https://phabricator.wikimedia.org/T285612]
* A &lt;code&gt;REL1_45&lt;/code&gt; branch for MediaWiki core and each of the extensions and skins in Wikimedia git has been created. This is the first step in the release process for MediaWiki 1.45.0, scheduled for late November 2025. If you are working on a critical bug fix or working on a new feature, you may need to take note of this change. [https://lists.wikimedia.org/hyperkitty/list/wikitech-l@lists.wikimedia.org/thread/ZUY7TY3Z6XPZWZVAZV63OPO5OW52Q6GE/]
* The process for generating CirrusSearch dumps has been updated due to slowing performance. If you encounter any issues migrating to the replacement dumps, please contact the Search Platform Team for support.

'''Updates for editors'''
* The [[mw:Special:MyLanguage/Readers/Reader Experience|Reader Experience team]] is experimenting with [[mw:Special:MyLanguage/Readers/Reader Experience/WE3.3.4_Reading lists|reading lists on mobile web]], allowing logged-in readers with no edits to save private lists of articles for later. The experiment is running on Arabic, Chinese, French, Indonesian, and Vietnamese Wikipedias since the week of 10 November, and will begin on English Wikipedia the week of 17 November.
* Users who can’t receive their email verification code during login can now get help by submitting a form on a new special page. This update is part of the [[mw:Special:MyLanguage/Product Safety and Integrity/Account Security|Account Security]] initiative. If your account has an email address, please make sure you still have access to it. When logging in from a new device or location without 2FA, you may be asked to enter a 6-digit code sent by email to finish logging in. [[mw:Special:MyLanguage/Product Safety and Integrity/Account Security#Why are you requiring me to enter a code from my email to log in? Can I opt out of this?|Learn more]].
* One new wiki has been created: a {{int:project-localized-name-group-wikisource}} in [[d:Q13324|Minangkabau]] ([[s:min:|&lt;code&gt;s:min:&lt;/code&gt;]]) [https://phabricator.wikimedia.org/T408317]

'''Updates for technical contributors'''
* As part of the [[mw:Special:MyLanguage/Parsoid/Parser Unification|Parser Unification]] project, the Content Transform Team rolled out Parsoid as the default parser to many low-traffic Wikipedias and is preparing the next step to high traffic ones. This message is an invitation for you to opt-in to Parsoid, as described in the [[mw:Special:MyLanguage/Help:Extension:ParserMigration|Extension:ParserMigration]] documentation, and identify any issues you might encounter with your own workflow using bots, gadgets, or user scripts. Please, let us know through the ''&quot;Report Visual Bug&quot;'' link in the Tools sidebar or create a phab ticket and tag the [[phab:project/view/5846|Content Transform Team in Phabricator]].
* Unsupported Tools: Several issues with [[:c:Special:MyLanguage/Commons:Video2commons|Video2Commons]] have been fixed, including filename-related upload failures, black-video imports, and retry handling. AV1 support has also been added. Ongoing work focuses on backend stability, ffmpeg errors, subtitle imports, metadata handling, and playlist uploads. To track specific tasks, check the [[phab:tag/video2commons/|Phabricator board]].

'''Updates for editors'''
* Last week, the [[mw:Special:MyLanguage/Wikimedia Search Platform|Wikimedia Search Team]] recreated the &quot;DWIM&quot; (Do What I Mean) gadget functionality server-side, for Russian and Hebrew Wikipedias. This feature adds cross-keyboard suggestions to the standard search-box suggestions. For example, searching for ''&lt;span lang=&quot;und&quot; dir=&quot;ltr&quot;&gt;cxfcnmt&lt;/span&gt;'' on Russian Wikipedia will now add suggestions for ''&lt;span lang=&quot;ru&quot; dir=&quot;ltr&quot;&gt;счастье&lt;/span&gt;'' (&quot;happiness&quot;) that the user probably intended. They plan to enable this feature for other Russian and Hebrew wikis this week. [https://phabricator.wikimedia.org/T408734]
* Later this week, users of the &quot;{{int:codemirror-beta-feature-title}}&quot; [[Special:Preferences#mw-prefsection-betafeatures|beta feature]] will have syntax highlighting available in [[mw:Special:MyLanguage/Help:DiscussionTools|DiscussionTools]]. This requires that the &quot;{{int:discussiontools-preference-sourcemodetoolbar}}&quot; preference be set. [https://phabricator.wikimedia.org/T407918]
* [[mw:Special:MyLanguage/Help:Extension:CampaignEvents|Campaign events extension]] – the set of tools for coordinating events and other on-wiki collaborations has now been deployed to all Wikimedia wikis. A new feature known as [[m:Special:MyLanguage/CampaignEvents/Collaborative contributions|Collaborative contribution]] to help organizers and participants see the impact of activities has also been added. Join the upcoming [[m:Special:MyLanguage/Event:Connection learning session 3|learning session]] to see the new feature in action and share your feedback.

'''Updates for technical contributors'''
*  Users of Wikimedia API can join a usability study to help validate the new design of Wikimedia REST API sandboxes. Interested participants should fill the [https://wikimediafoundation.limesurvey.net/487662 recruitment survey]. [https://lists.wikimedia.org/hyperkitty/list/wikitech-l@lists.wikimedia.org/thread/IREJRRWTZTGCYWQHDMSNJFTQAEPOOAE3/]
* The MediaWiki Interfaces team is deprecating XSLT stylesheets within the Action API. Support for &lt;code dir=ltr&gt;format=xml'''&amp;xlst={stylesheet}'''&lt;/code&gt; will be removed from Wikimedia projects by the end of November, 2025. In addition, it will soon be disabled by default in MediaWiki release versions: v1.43 (LTS), v1.44, and v1.45. Support for XSLT stylesheets will be fully removed from MediaWiki v1.46 (expected to release between April and May 2026). [https://lists.wikimedia.org/hyperkitty/list/wikitech-l@lists.wikimedia.org/thread/5AX7UWAVVUNUSBOIRHMNOKWOZ5EZI3JX/]
* The WDQS legacy endpoint ([https://query-legacy-full.wikidata.org/ query-legacy-full.wikidata.org]) will be decommissioned at the end of December 2025, and finally closed down on 7th January 2026. After this date, users should expect requests to query.wikidata.org that require the full graph to fail or return invalid results if they are not rewritten to use SPARQL federation. The team encourages users to ensure that tools and workflows use the supported WDQS endpoints (&lt;span dir=ltr&gt;&lt;nowiki&gt;https://query.wikidata.org/&lt;/nowiki&gt;&lt;/span&gt; - Main graph or &lt;span dir=ltr&gt;&lt;nowiki&gt;https://query-scholarly.wikidata.org/&lt;/nowiki&gt;&lt;/span&gt; - Scholarly graph). For support with migrating use cases, please review the [[d:Special:MyLanguage/Wikidata:Data_access|Data Access]] and [[d:Wikidata:Request_a_query|Request a Query]] pages for details and assistance on alternative access methods.

'''Updates for editors'''
* The Wikipedia Year in Review 2025 will be available on December 2 for users of iOS and Android Wikipedia apps, featuring new personalized insights, updated reading highlights, and refreshed designs. Learn more on the review's [[mw:Special:MyLanguage/Wikimedia Apps/Team/Wikipedia Year in Review/Updates|project page]].
* The Growth team is working on improving the text and presentation of the Verification Email sent to new users to make them more welcoming, useful and informative. Some new text have been drafted for A/B testing and you can help by translating them. See [[phab:T396155|Phabricator]].
* [[mw:Special:MyLanguage/Help:Growth/Tools/Add a link|Add a link]] will now be deployed at Japanese, Urdu and Chinese Wikipedias on December 2. Add a link is based on a prediction model that suggests links to be added to articles. While this feature has already been available on most Wikipedias, the prediction model could not support certain languages. A new model has now been developed to handle these languages, and it will be gradually rolled out to other Wikipedias over time. If you would like to know more, please contact [[mw:user:Trizek (WMF)|Trizek (WMF)]].

'''In depth'''
* The Wikimedia Foundation is in the early stages of exploring approaches to '''Article guidance'''. The initiative aims to identify interventions that could help new editors easily understand and apply existing Wikipedia practices and policies when creating an article. The project is in the exploration and early experimental design phase. All community members are encouraged to [[mw:Special:MyLanguage/Article guidance|learn more]] about the project, and share their thoughts on [[mw:Special:MyLanguage/Talk:Article guidance|the talk page]].

'''Weekly highlight'''
* Anybody who wishes to secure their user account can now use [[m:Special:MyLanguage/Help:Two-factor authentication|two-factor authentication]] (2FA). This is available to all registered users of all Wikimedia projects. This is part of the [[mw:Special:MyLanguage/Product Safety and Integrity/Account Security|Account Security]] initiative. Later, 2FA will be required for all users who can take security- or privacy-sensitive actions.

'''Updates for editors'''
* Following last week's deployments, the [[mw:Special:MyLanguage/Help:Growth/Tools/Add a link|Add a link]] feature, which allows editors to add suggested links during editing, will be available to an additional [[Phab:T410469|33 Wikipedias]] starting on 9 December. This expansion is possible thanks to the new prediction model that now supports all languages, including those that were previously not covered. While the feature has been available on most Wikipedias for some time, this rollout brings us closer to using the improved model everywhere. If you have any questions or would like more details please contact [[mw:user:Trizek (WMF)|Trizek (WMF)]].
* Last week, the [[mw:Special:MyLanguage/Wikimedia Search Platform|Search Platform team]] added [[w:en:Transliteration|transliterated]] as-you-type search suggestions to Georgian wikis. If there are only a few regular search suggestions, then queries in Latin or Cyrillic script [[phab:T127003|are now rewritten into Georgian script]] to look for more matches. For example, searching for either &lt;bdi lang=&quot;ka-Latn&quot; dir=&quot;ltr&quot;&gt;''bedniereba''&lt;/bdi&gt; or &lt;bdi lang=&quot;ka-Cyrl&quot; dir=&quot;ltr&quot;&gt;''бедниереба''&lt;/bdi&gt; will now suggest the existing article about &lt;bdi lang=&quot;ka&quot; dir=&quot;ltr&quot;&gt;ბედნიერება&lt;/bdi&gt; (&quot;happiness&quot;). You can recommend other languages where transliterated suggestions would be useful [[phab:T375215|on Phabricator]] for future development.
* Later this week, a controlled experiment will begin for editors on the 100 largest Wikipedias who are editing a section in the mobile web visual editor. 50% of these editors will notice a new &quot;Edit full page&quot; button that will enable them to expand their editing session to the whole page. This feature is intended to make it easier for people on mobile web to edit any article section, regardless of which section-edit icon they tapped to begin. The experiment will last ~4 weeks. You can find [[phab:T409112|more details]] about the project.
* Later this week, the [[mw:Special:MyLanguage/Readers/Reader Growth|Reader Growth team]] will launch a [[mw:Special:MyLanguage/Readers/Reader Growth/WE3.1.14 Expanded Mobile Sections|mobile web experiment]] to expand all article sections by default (currently they are collapsed by default) and pin the section header the user is currently reading to the top of the page. The experiment will affect 10% of users on Arabic, Chinese, French, Indonesian, and Vietnamese Wikipedias. [https://phabricator.wikimedia.org/T409485]
* The [[mw:Special:MyLanguage/Wikimedia Apps/Team/Wikipedia Year in Review/2025 Year in Review|Wikipedia Year in Review 2025]], a feature in the Wikipedia mobile apps (iOS and Android) that provides users with a personalised summary of their engagement with Wikipedia over the year, is now available on the iOS and Android apps. This edition includes expanded personalised insights, improved reading highlights, new donor messaging, and updated designs. Open the app to view your Year in Review and explore your reading journey from 2025.
* A recent software bug caused edits made with VisualEditor to make unintended changes to wikitext, including removing whitespace and replacing spaces with underscores in wikilinks inside citations. This was partially fixed last week, and further fixes are in progress. Editors who used VisualEditor between November 28 and December 2 should review their edits for unexpected modifications.

'''Updates for technical contributors'''
* Starting this week, users of the &quot;{{int:codemirror-beta-feature-title}}&quot; [[Special:Preferences#mw-prefsection-betafeatures|beta feature]] will have [[mw:Special:MyLanguage/Help:Extension:CodeMirror|CodeMirror]] as the editor for Lua, JavaScript, CSS, JSON and Vue content models, instead of [[mw:Special:MyLanguage/Extension:CodeEditor|CodeEditor]]. With this, the [[mw:Special:MyLanguage/Help:Extension:CodeMirror#Linting|linters]] will be upgraded. This is part of a larger effort to eventually replace CodeEditor and provide a consistent code editing experience. [https://phabricator.wikimedia.org/T373711]

'''Updates for technical contributors'''
* To improve database and site performance, external links to Wikimedia projects will no longer be stored in the database.

* Interface elements such as diffs and categories generated by MediaWiki used to have the attribute &lt;code dir=ltr&gt;data-mw=&quot;interface&quot;&lt;/code&gt; to distinguish from wiki content. The attribute has been replaced with &lt;code dir=ltr&gt;data-mw-interface=&quot;&quot;&lt;/code&gt;, to avoid potential conflicts with other &lt;code dir=ltr&gt;data-mw&lt;/code&gt; attributes, which are generated by Parsoid.

Additionally, the pagination on [[Special:Search|Search]] will be updated too, as a part of the work on the [[m:Special:MyLanguage/Community Wishlist/W186|Revamp pagination / page navigation]] wish. [https://phabricator.wikimedia.org/T411596]
* [[m:Special:GlobalWatchlist|The Global Watchlist]] is a MediaWiki [[mw:Special:MyLanguage/Extension:GlobalWatchlist|extension]] that lets you see your watchlists from different wikis on the same page. It was recently updated to look more like the regular [[Special:Watchlist|Watchlist]], such as preparing it for temporary accounts in IP masking (including rerouting user links to contributions pages), making page titles bold, and opening links in edit summaries and tags in new browser tabs.

* The tray shown on [[Special:Diff|Special:Diff]] in mobile view has been redesigned.

[https://phabricator.wikimedia.org/T402297] 
* [[m:Special:GlobalWatchlist|The Global Watchlist]] lets you view your watchlists from multiple wikis on one page. The [[mw:Special:MyLanguage/Extension:GlobalWatchlist|extension]] continues to improve — it now automatically determines the text direction (ensuring correct display of sites with unusual domain names) and shows detailed descriptions for log actions. Later this week, a new permanent link for page creations and CSS classes for each entry element will be added.

'''Updates for technical contributors'''
* As mentioned in the [[m:Special:MyLanguage/Tech/News/2025/44|October 2025 deprecation announcement]], MediaWiki Interfaces team will begin sunsetting all transform endpoints containing a trailing slash from the MediaWiki REST API the week of January 26. Changes are expected to roll out to all wikis on or before January 30th. All API users currently calling them are encouraged to transition to the non-trailing slash versions. Both endpoint variations can be found, compared, and tested using the [https://test.wikipedia.org/wiki/Special:RestSandbox REST Sandbox]. If you have questions or encounter any problems, please file a ticket in Phabricator to the [https://phabricator.wikimedia.org/project/view/6931/ #MW-Interfaces-Team board].
* Interactive reference documentation for the [[mw:Special:MyLanguage/Wikimedia REST API|Wikimedia REST API]] has moved. Requests to API docs previously hosted through [[mw:Special:MyLanguage/RESTBase|RESTBase]] (e.g.: &lt;code dir=ltr&gt;https://en.wikipedia.org/api/rest_v1/&lt;/code&gt;) are now redirected to the [[w:en:Special:RestSandbox|REST Sandbox]].
* The [[mw:Special:MyLanguage/Wikidata Platform|WMF Wikidata Platform team]] (WDP) has published its [[d:Special:MyLanguage/Wikidata:Wikidata Platform team/Newsletter|January 2026 newsletter]]. It includes updates on the legacy full-graph endpoint decommissioning, the User-Agent policy change, the monthly Blazegraph migration office hours, and efforts to reduce regressions caused by the legacy endpoint shutdown.

* Wikimedia Foundation invites comments on [[m:Special:MyLanguage/Product and Technology Advisory Council/Year1 Reflections and Proposed Way Forward 2026 Update|proposed future]] of the [[:m:Special:MyLanguage/Product and Technology Advisory Council|Product and Technology Advisory Council]] until 28 February.
* All users with registered accounts can now use passkeys for [[m:Special:MyLanguage/Help:Two-factor authentication|two-factor authentication]] (2FA). Passkeys are a simple way to log in without using a second device. They verify the user's identity using a fingerprint, face scan, or a PIN code. To set up a passkey, first set up a regular 2FA method. Currently, to log in with a passkey, users must also use a password. Later this quarter, passwordless login will allow users to log in with a single click and a passkey. Users with advanced rights will also be required to have 2FA enabled. This is part of the [[mw:Special:MyLanguage/Product Safety and Integrity/Account Security|Account Security]] project.
* Unregistered contributors on blocked IPs or blocked IP ranges can now interact on-wiki to appeal a block by creating a temporary account to appeal a block on the user talk page, unless the &quot;prevent this user from editing their own talk page&quot; is enabled. This solves the problem of logged-out users unable to use the default unblock process via user talk page. [https://phabricator.wikimedia.org/T398673]

[https://phabricator.wikimedia.org/T332385]

'''Updates for technical contributors'''
* A new AbuseFilter variable, &lt;code&gt;account_type&lt;/code&gt;, has been added to provide a reliable way to determine the account type being created in the &lt;code&gt;createaccount&lt;/code&gt; and &lt;code&gt;autocreateaccount&lt;/code&gt; actions. As part of this change, the variable &lt;code&gt;accountname&lt;/code&gt; has been renamed to &lt;code&gt;account_name&lt;/code&gt;, and &lt;code&gt;accountname&lt;/code&gt; is now deprecated. Edit filter managers should update any filters that use hardcoded account type checks or the deprecated variable. [https://phabricator.wikimedia.org/T414049]
* Image thumbnails that are requested in non-standard sizes, and using non-standard methods such as direct requests to &lt;code dir=ltr&gt;&lt;nowiki&gt;upload.wikimedia.org/…&lt;/nowiki&gt;&lt;/code&gt; will stop working in the near future. This change is to prevent ongoing external abuse by web-scrapers and bots. Some users with custom CSS/JS, Interface Admins who can fix gadgets and local skins, and Tool-authors, will need to update their code to use standard thumbnail sizes. [[phab:T414805|Details, search-links, and examples of how to fix them, are available in the task]].

* [[File:Maki-gift-15.svg|12px|link=|class=skin-invert|Wishlist item]] Logged-in contributors who manage large or complex watchlists can now organise and filter watched pages in ways that improve their workflows with the new [[mw:Special:MyLanguage/Help:Watchlist labels|Watchlist labels]] feature. By adding custom labels (for example: pages you created, pages being monitored for vandalism, or discussion pages) users can more quickly identify what needs attention, reduce cognitive load, and respond more efficiently. This improves watchlist usability, especially for highly active editors.
* A new feature available on [[Special:Contributions|Special:Contributions]] shows [[mw:Special:MyLanguage/Trust and Safety Product/Temporary Accounts|temporary accounts]] that are likely operated by the same person, and so makes patrolling less time-consuming. Upon checking contributions of a temporary account, users with access to temporary account IP addresses can now see a view of contributions from the related temporary accounts. The feature looks up all the IPs associated with a given temporary account within the data retention period and shows all the contributions of all temporary accounts that have used these IPs. [[mw:Special:MyLanguage/Trust and Safety Product/Temporary Accounts#February 2026: Improvements to the patroller tooling|Learn more]]. [https://phabricator.wikimedia.org/T415674] 
* When editors preview a wikitext edit, the reminder box that they are only seeing a preview (which is shown at the top), now has a grey/neutral background instead of a yellow/warning background. This makes it easier to distinguish preview notes from actual warnings (for example, edit conflicts or problematic redirect targets), which will now be shown in separate warning or error boxes. [https://phabricator.wikimedia.org/T414742]
* The [[m:Special:GlobalWatchlist|Global Watchlist]] lets you view your watchlists from multiple wikis on one page. The [[mw:Special:MyLanguage/Extension:GlobalWatchlist|extension]] continues to improve — it now properly supports more than one Wikibase site, for example both [[d:|Wikidata]] and [[testwikidata:|testwikidata]]. In addition, issues regarding text direction have been fixed for users who prefer Wikidata or other Wikibase sites in right-to-left (RTL) languages. [https://phabricator.wikimedia.org/T415440][https://phabricator.wikimedia.org/T415458]
* The automatic &quot;magic links&quot; for ISBN, RFC, and PMID numbers have been [[mw:Special:MyLanguage/Help:Magic links|deprecated in wikitext since 2021]] due to inflexibility and difficulties with localization. Several wikis have successfully replaced RFC and PMID magic links with equivalent external links, but a template was often required to replace the functionality of the ISBN magic link. There is now a new [[mw:Special:MyLanguage/Help:Magic words#isbn|built-in parser function]] &lt;code dir=ltr&gt;&lt;nowiki&gt;{{#isbn}}&lt;/nowiki&gt;&lt;/code&gt; available to replace the basic functionality of the ISBN magic link. This makes it easier for wikis who wish to migrate off of the deprecated magic link functionality to do so. [https://phabricator.wikimedia.org/T145604]
* Two new wikis have been created: 
** a {{int:project-localized-name-group-wikipedia}} in [[d:Q35401|Jju]] ([[w:kaj:|&lt;code&gt;w:kaj:&lt;/code&gt;]]) [https://phabricator.wikimedia.org/T413283]

'''Updates for technical contributors'''
* A new global user group has been created: [[{{int:grouppage-local-bot}}|{{int:group-local-bot}}]]. It will be used internally by the software to allow community bots to bypass rate limits that are applied to abusive [[w:en:Web scraping|web scrapers]]. Accounts that are approved as bots on at least one Wikimedia wiki will be automatically added to this group. It will not change what user permissions the bot has. [https://phabricator.wikimedia.org/T415588]
* [[File:Reload icon with two arrows.svg|12px|link=|class=skin-invert|Recurrent item]] Detailed code updates later this week: [[mw:MediaWiki 1.46/wmf.15|MediaWiki]]

'''Meetings and events'''
* The [[mw:Special:MyLanguage/MediaWiki Users and Developers Conference Spring 2026|MediaWiki Users and Developers Conference, Spring 2026]] will be held March 25–27 in Salt Lake City, USA. This event is organized by and for the third-party MediaWiki community. You can propose sessions and register to attend.

'''Weekly highlight'''
* The [[mw:Special:MyLanguage/Wikimedia Site Reliability Engineering|SRE Team]] will be performing a cleanup of Wikimedia's [[m:Special:MyLanguage/Etherpad|Etherpad]] instance, the web-based editor for real-time collaborative document editing. All pads will be permanently deleted after 30 April, 2026 – if there are still migration projects in progress at that point the team can revisit the date on a case by case basis. Please create local backups of any content you wish to keep, as deleted data cannot be recovered. This cleanup helps reduce database size and minimize infrastructure footprint. Etherpad will continue to support real-time collaboration, but long-term storage should not be expected. Additional cleanups may occur in the future without prior notice. [https://phabricator.wikimedia.org/T415237]

'''Updates for editors'''
* The Information Retrieval team will be launching an [[mw:Special:MyLanguage/Readers/Information Retrieval/Phase 1|Android mobile app experiment]] that tests hybrid search capabilities which can handle both semantic and keyword queries. The improvement of on-platform search will enable readers to find what they’re looking for directly on Wikipedia more easily. The experiment will first be launched on Greek Wikipedia in late February, followed by English, French, and Portuguese in March. [https://diff.wikimedia.org/2026/01/08/semantic-search-making-it-easier-to-find-the-information-readers-want/ Read more] on Diff blog. [https://www.mediawiki.org/wiki/Readers/Information_Retrieval]
* The Reader Growth team will run [[mw:Special:MyLanguage/Readers/Reader Growth/WE3.10.2 Mobile Table of Contents|an experiment]] for mobile web users, that adds a table of contents and automatically expands all article sections, to learn more about navigation issues they face. The test will be available on Arabic, Chinese, English, French, Indonesian, and Vietnamese Wikipedias.
* Previously, site notices ([[{{ns:8}}:Sitenotice]] and [[{{ns:8}}:Anonnotice]]) would only render on the desktop site. Now, they will render on all platforms. Users on mobile web will now see these notices and be informed. Site administrators should be prepared to test and fix notices on mobile devices to avoid interference with articles. To opt out, interface admins can add &lt;code dir=&quot;ltr&quot;&gt;#siteNotice { display: none; }&lt;/code&gt; to [[{{ns:8}}:Minerva.css]].

Previously, clicking hide in the active filters caused the &quot;view new changes since…&quot; button to disappear, though it should have remained visible. The button now behaves as expected. [https://phabricator.wikimedia.org/T406339]

'''Updates for technical contributors'''
* New documentation is now available to help editors debug on-site search features. It supports troubleshooting when pages do not appear in results, when ranking seems unexpected, and when you need to inspect what content is being indexed, helping make search behavior easier to understand and analyze. [[mw:Help:CirrusSearch/Debug|Learn more]]. [https://phabricator.wikimedia.org/T411169]

'''Weekly highlight'''
* [[mw:Special:MyLanguage/Edit check/Reference Check|Reference Check]] has been deployed to English Wikipedia, completing its rollout across all Wikipedias. The feature prompts newcomers to add a citation before publishing new content, helping reduce common citation-related reverts and improve verifiability. In A/B testing, the impact was substantial: newcomers shown Reference Check were approximately 2.2 times more likely to include a reference on desktop and about 17.5 times more likely on mobile web. [https://analytics.wikimedia.org/published/reports/editing/reference_check_ab_test_report_final_2025.html]
'''Updates for editors'''
* The [[mw:Special:MyLanguage/Extension:InterwikiSorting|InterwikiSorting extension]], which allowed for the [[m:Special:MyLanguage/Interwiki sorting order|sorting of interwiki links]], has been undeployed from Wikipedia. As a result, editors who had enabled interwiki link sorting in non-compact mode (full list format) will now see links reordered. The links moving forward will be listed in the alphabetical order of language code. [https://phabricator.wikimedia.org/T253764]
* Later this week, people who are editing a page-section using the mobile visual editor, will notice a new &quot;Edit full page&quot; button. When tapped, you will be able to edit the entire article. This helps when the change you want to make is outside the section you initially opened. [https://phabricator.wikimedia.org/T387175][https://phabricator.wikimedia.org/T409112]
* [[mw:Special:MyLanguage/Readers/Reader Experience|The Reader Experience team]] is inviting editors to assess whether dark mode should still be considered &quot;beta&quot; on their wiki, based on their experience of how well it functions on desktop and mobile. If the feature is deemed mature, editors can update the interface messages in &lt;code dir=ltr&gt;MediaWiki:skin-theme-description&lt;/code&gt; and &lt;code dir=ltr&gt;MediaWiki:Vector-night-mode-beta-tag&lt;/code&gt; to indicate that dark mode is ready and no longer considered beta.
* The improved [[mw:Wikimedia_Apps/Team/iOS/Activity_Tab|Activity tab]] which displays user-insights is now available to all users of the Wikipedia iOS app (version 7.9.0 and later). Following earlier A/B testing that showed higher account creation among users with access to the feature, it has been rolled out to 100% of users along with some updates. The Activity tab now shows your edited articles in the timeline, offers editing impact insights like contribution counts and article view trends, and customization options to improve in-app experience for users.

[https://phabricator.wikimedia.org/T415303]

'''Updates for technical contributors'''
* The [[m:Special:GlobalWatchlist|Global Watchlist]] lets you view your watchlists from multiple wikis on one page. The [[mw:Special:MyLanguage/Extension:GlobalWatchlist|extension]] that makes this possible continues to improve. The latest upgrade is the inclusion of a [[mw:Extension:GlobalWatchlist#hook|new hook]], &lt;code dir=ltr&gt;ext.globalwatchlist.rebuild&lt;/code&gt;, which fires after each watchlist rebuild. This allows you to run gadgets and user scripts for the Special page. [https://phabricator.wikimedia.org/T275159]

'''Weekly highlight'''
* Wikipedia 25 [[m:Special:MyLanguage/Wikipedia 25/Easter egg experiments|Birthday mode]] is now live on Betawi, Breton, Chinese, Czech, Dutch, English, French, Gorontalo, Indonesian, Italian, Luxembourgish, Madurese, Sicilian, Spanish, Thai, and Vietnamese Wikipedias! This limited-time campaign feature celebrates 25 years of Wikipedia with a birthday mascot, Baby Globe. When turned on, Baby Globe is shown on [[m:Special:MyLanguage/Wikipedia 25/Easter egg experiments/article configuration|~2,500 articles]], waiting to be discovered by readers. Communities can choose to turn Birthday mode on by getting consensus from their community and asking an admin to enable the feature and customize it via [[m:Special:MyLanguage/Wikipedia 25/Easter egg experiments#Community Configuration Demo|community configuration]] on the local wiki.

'''Updates for editors'''
* [[:m:Special:MyLanguage/WMDE Technical Wishes/Sub-referencing|Sub-referencing]], a new feature to re-use references with different details has been released to Swedish Wikipedia, Polish Wikipedia and [[:phab:T418209|a couple of other wikis]]. You can [[:m:Special:MyLanguage/WMDE Technical Wishes/Sub-referencing#test|try the feature]] on these projects or on testwiki and [https://en.wikipedia.beta.wmcloud.org/wiki/Sub-referencing betawiki]. Learnings from the first pilot wiki German Wikipedia have been [[:m:Special:MyLanguage/WMDE Technical Wishes/Sub-referencing/Learnings|published in a report]]. Reach out to the Wikimedia Deutschland team if you are [[:m:Talk:WMDE Technical Wishes/Sub-referencing#Pilot wikis|interested in becoming a pilot wiki]].
* [[mw:Special:MyLanguage/Help:Edit check#Paste check|Paste Check]] will become available at all Wikipedias this week. The feature prompts newcomers who are pasting text they are not likely to have written into VisualEditor to consider whether doing so risks a copyright violation. Paste Check [[mw:Special:MyLanguage/Edit check/Tags|tags]] all edits where it is shown for potential review. Local administrators can configure various aspects of the feature via [[{{#special:EditChecks}}]]. [[mw:Special:MyLanguage/Edit check/Paste Check#A/B Experiment|Research]] across 22 wikis found that Paste Check resulted in an 18% decrease in relative reverted-edits compared to the control group. Translators can [https://translatewiki.net/w/i.php?title=Special%3ATranslate&amp;group=ext-visualeditor-ve-mw-editcheck&amp;filter=&amp;optional=1&amp;action=translate help to localize] this and related features.
* The [[mw:Special:MyLanguage/Readers/Reader Experience|Reader Experience team]] will be standardizing the user menu in the top right for all mobile users so that it is closer to the desktop experience. Currently this user menu is only visible to users with Advanced Mobile Controls (AMC) turned on. The only change is that a couple buttons previously in the left-side menu will move to the top right for users who do not have AMC turned on. This change is expected to go out March 9 and seeks to improve the user interface. [https://phabricator.wikimedia.org/T413912]
* Starting in the week of March 2, the emails sent out when an email address was added, removed, or changed for an account will switch to a substantially nicer and clearer HTML email from the prior plaintext one. [https://phabricator.wikimedia.org/T410807]
* Notifications are currently limited to 2,000 historic entries per user, and extend back to 2013 when the feature was released. This is going to be changed to only store Notifications from the last 5 years, but up to 10,000 of them. This will help with long-term infrastructure health and help to prevent more recent notifications from disappearing too soon. [https://phabricator.wikimedia.org/T383948]
* The [[m:Special:GlobalWatchlist|Global Watchlist]] which lets you view your watchlists from multiple wikis on a single page continues to see improvements. The latest update improves label usage experience. The [[mw:Special:MyLanguage/Extension:GlobalWatchlist|extension]] now allows activating the [[mw:Special:MyLanguage/Manual:Language#Fallback languages|language fallback system]] for Wikidata items without labels in the viewed language, and showing those labels in the user’s preferred Wikidata language if no &lt;code dir=ltr&gt;uselang=&lt;/code&gt; URL parameter is provided. [https://phabricator.wikimedia.org/T373686][https://phabricator.wikimedia.org/T416111]
* The Wikipedia Android team has started a beta test of [[mw:Special:MyLanguage/Readers/Information Retrieval/Phase 1|hybrid search]] on Greek Wikipedia. Hybrid search capabilities can handle both semantic and keyword queries enabling readers to find what they’re looking for directly on Wikipedia more easily.
* For security reasons, members of certain user groups are [[m:Special:MyLanguage/Mandatory two-factor authentication for users with some extended rights|required to have two-factor authentication]] (2FA) enabled. Currently, 2FA is required to use the group, but not to be a member of it. Given that this model still has some vulnerabilities, the situation will [[phab:T418580|gradually change in March]]. Members of these groups will be unable to disable last 2FA method on their account, and it will be impossible to add users without 2FA to these groups. Users will still be able to add new authentication methods or remove them, as long as at least one method is continuously enabled. In the second half of March, users without 2FA will be removed from these groups. This applies to: CentralNotice administrators, checkusers, interface administrators, suppressors, Wikidata staff, Wikifunctions staff, WMF Office IT and WMF Trust &amp; Safety. Nothing will change for other users. See the linked task for deployment schedule. [https://phabricator.wikimedia.org/T418580]

'''Updates for technical contributors'''
* To help ensure [[mw:Special:MyLanguage/MediaWiki Product Insights/Responsible Reuse|fair use of infrastructure]], over the next month the Wikimedia Foundation will implement global API rate limits across our APIs. In early March, stricter limits will be applied to unidentified requests from outside Toolforge/WMCS and API requests that are made from web browsers. In April, higher limits will be applied to identified traffic. These limits are intentionally set as high as possible to minimise impact on the community. Bots running in Toolforge/WMCS or with the bot user right on any wiki should not be affected for now. However, all developers are advised to follow updated best practices. For more information, see [[mw:Special:MyLanguage/Wikimedia APIs/Rate limits|Wikimedia APIs/Rate limits]].
* The Wikidata Query Service Linked Data Fragment (LDF) endpoint will be decommissioned in February. This endpoint served limited traffic, which was successfully migrated to other data access methods that were better suited to support existing use cases. The hardware used to support the LDF endpoint will be reallocated to support the ongoing backend migration efforts. [https://phabricator.wikimedia.org/T415696]
* The new Parsoid parser [[mw:Special:MyLanguage/Parsoid/Parser Unification/Updates|continues to be deployed to additional wikis]], improving platform sustainability and making it easier to introduce new reading and editing features. Parsoid is now the default parser on 488 WMF wikis (268 Wikipedias), now covering more than 10% of all Wikipedia page views.
* The process and criteria for [[Special:MyLanguage/Wikimedia Enterprise#Access|requesting exceptional access]] to the high volume feed of the ''Wikimedia Enterprise'' APIs (at no cost for mission-aligned usecases), [[m:Talk:Wikimedia Enterprise#Exceptional access criteria|have now been published]]. This is to provide more thorough and clearer documentation for users.
* [https://techblog.wikimedia.org/ Tech Blog], the blog dedicated to the Wikimedia technical community [https://techblog.wikimedia.org/2026/02/24/a-tech-blog-diff/ will be migrating] to [[diffblog:|Diff]], the community news and event blog. The migration should be complete in April 2026, after which new posts will be accepted for publishing. Readers will be able to access posts – old and new – on the landing page at https://diff.wikimedia.org/techblog.

'''Weekly highlight'''
* [[m:Special:MyLanguage/Tech/Server switch|All wikis will be read-only]] for a few minutes on Wednesday, 25 March 2026 at [https://zonestamp.toolforge.org/1774450800 15:00 UTC]. This is for the datacenter server switchover backup tests, [[wikitech:Deployments/Yearly calendar|which happen twice a year]]. During the switchover, all Wikimedia website traffic is shifted from one primary data center to the backup data center to test availability and prevent service disruption even in emergencies.
* Last week, all wikis had 2 hours of read-only time, and extended unavailability for user-scripts and gadgets. This was due to a security incident which has since been resolved. Work is ongoing to prevent re-occurrences. For current information please see the [[m:Steward's noticeboard#Statement on Meta about today's user script security incident|post on the Stewards' noticeboard]] ([[m:Special:MyLanguage/Wikimedia Foundation/Product and Technology/Product Safety and Integrity/March 2026 User Script Incident|translations]]).

'''Updates for editors'''
* Users facing multiple blocks on mobile will now see the reasons for each block separately, instead of a generic message. This helps them understand why they are blocked and what steps they can take to resolve the issue. For example, users affected for using common VPNs (such as [[Special:MyLanguage/Apple iCloud Private Relay|iCloud Private Relay]]) will receive clearer guidance on what they need to do to start editing again. [https://phabricator.wikimedia.org/T357118]
* Later this week, [[mw:Special:MyLanguage/VisualEditor/Suggestion Mode|Suggestion Mode]] will become available as a beta feature within the visual editor at all Wikipedias. This feature proactively suggests various types of actions that people can consider taking to improve Wikipedia articles, and learn about related guidelines. The feature is locally configurable, and can also be locally expanded with custom Suggestions. Current settings can be seen at [[Special:EditChecks]] and there are [[mw:Special:MyLanguage/Help:Suggestion mode#For administrators %E2%80%93 local customization|instructions for how administrators can customize]] the links to point to local guidelines. The feature is connected to [[mw:Special:MyLanguage/Help:Edit check|Edit check]] which suggests improvements while someone is writing new content. In the future, the Editing team plans to evaluate the feature's impact with newcomers through a controlled experiment. [https://phabricator.wikimedia.org/T404600]

* API rate limiting update: To help ensure [[mw:Special:MyLanguage/MediaWiki Product Insights/Responsible Reuse|fair use of infrastructure]], global API rate limits will be applied this week to requests without a compliant User-Agent that originate from outside Toolforge/WMCS and to unauthenticated requests made from web browsers. Higher limits will be applied to identified traffic in April. Bots running in Toolforge/WMCS or with the bot user right on any wiki should not be affected for now. However, all developers are advised to follow updated best practices. For more information, see [[mw:Special:MyLanguage/Wikimedia APIs/Rate limits|Wikimedia APIs/Rate limits]].
* The new GraphQL API has been released. The API was developed as a flexible alternative to select features of the Wikidata Query Service (WDQS), to improve developer experience and foster adaptability, and efficient data access. Try it out and [[d:Wikidata:Wikibase GraphQL#Feedback and development|give feedback]]. You can also [https://greatquestion.co/wikimediadeutschland/GraphQLAPI/apply sign up for usability tests].
* The [[m:Special:MyLanguage/Product and Technology Advisory Council/Unsupported Tools Working Group|PTAC Unsupported Tools Working Group]] continued improvements to [[commons:Special:MyLanguage/Commons:Video2commons#|Video2Commons]] in February, with fixes addressing authentication errors, large-file handling, task queue visibility, and clearer upload behavior. Work is still ongoing in some areas, including changes related to deprecated server-side uploads. Read [[m:Special:MyLanguage/Product and Technology Advisory Council/Unsupported Tools Working Group#February 2026|this update]] to learn more.

'''Updates for editors'''
* The [[mw:Special:MyLanguage/Help:Extension:CodeMirror|{{int:codemirror-beta-feature-title}}]] beta feature, also known as [[mw:Special:MyLanguage/Extension:CodeMirror|CodeMirror 6]], has been used for wikitext syntax highlighting since November 2024. It will be promoted out of beta by May 2026 in order to bring improvements and new [[mw:Special:MyLanguage/Help:Extension:CodeMirror#Features|features]] to all editors who use the standard syntax highlighter. If you have any questions or concerns about promoting the feature out of beta, [[mw:Special:MyLanguage/Help talk:Extension:CodeMirror|please share]]. [https://phabricator.wikimedia.org/T259059]
* Some changes to local user groups are performed by stewards on Meta-Wiki and logged there only. Now, interwiki rights changes will be logged both on Meta-Wiki and the wiki of the target user to make it easier to access a full record of user's rights changes on a local wiki. Past log entries for such changes will be backfilled in the coming weeks. [https://phabricator.wikimedia.org/T6055]
* On wikis using [[m:Special:MyLanguage/Flagged Revisions|Flagged Revisions]], the number of pending changes shown on [[{{#Special:PendingChanges}}]] previously counted pages which were no longer pending review, because they have been removed from the system without being reviewed, e.g. due to being deleted, moved to a different namespace, or due to wiki configuration changes. The count will be correct now. On some wikis the number shown will be much smaller than before. There should be no change to the list of pages itself. [https://phabricator.wikimedia.org/T413016]
* Wikifunctions composition language has been rewritten, resulting in a new version of the language. This change aims to increase service stability by reducing the orchestrator's memory consumption. This rewrite also enables substantial latency reduction, code simplification, and better abstractions, which will open the door to later feature additions. Read more about [[f:Special:MyLanguage/Wikifunctions:Status updates/2026-03-11|the changes]].
* Users can now sort search results alphabetically by page title. The update gives an additional option to finding pages more easily and quickly. Previously, results could be sorted by Edit date, Creation date, or Relevance. To use the new option, open 'Advanced Search' on the search results page and select 'Alphabetically' under 'Sorting Order'. [https://phabricator.wikimedia.org/T403775]
* [[File:Reload icon with two arrows.svg|12px|link=|class=skin-invert|Recurrent item]] View all {{formatnum:28}} community-submitted {{PLURAL:28|task|tasks}} that were [[m:Special:MyLanguage/Tech/News/Recently resolved community tasks|resolved last week]]. For example, the bug that prevented UploadWizard on Wikimedia Commons from importing files from Flickr has now been fixed. [https://phabricator.wikimedia.org/T419263]
'''Updates for technical contributors'''
* A new special page, [[{{#special:LintTemplateErrors}}]], has been created to list transcluded pages that are flagged as containing lint errors to help users discover them easily. The list is sorted by the number of transclusions with errors. For example: [[{{#special:LintTemplateErrors}}/night-mode-unaware-background-color]]. [https://phabricator.wikimedia.org/T170874]
* Users of the [[mw:Special:MyLanguage/Help:Extension:CodeMirror|{{int:codemirror-beta-feature-title}}]] beta feature have been using [[mw:Special:MyLanguage/Extension:CodeMirror|CodeMirror]] instead of [[mw:Special:MyLanguage/Extension:CodeEditor|CodeEditor]] for syntax highlighting when editing JavaScript, CSS, JSON, Vue and Lua content pages, for some time now. Along with promoting CodeMirror 6 out of beta, the plan is to replace CodeEditor as the standard editor for these content models by May 2026. [[mw:Special:MyLanguage/Help talk:Extension:CodeMirror|Feedback or concerns are welcome]]. [https://phabricator.wikimedia.org/T419332]
* The [[mw:Special:MyLanguage/Extension:CodeMirror|CodeMirror]] JavaScript modules will soon be upgraded to CodeMirror 6. Leading up to the upgrade, loading the &lt;code dir=ltr&gt;ext.CodeMirror&lt;/code&gt; or &lt;code dir=ltr&gt;ext.CodeMirror.lib&lt;/code&gt; modules from gadgets and user scripts was deprecated in July 2025. The use of the &lt;code dir=ltr&gt;ext.CodeMirror.switch&lt;/code&gt; hook was also deprecated in March 2025. Contributors can now make their scripts or gadgets compatible with CodeMirror 6. See the [[mw:Special:MyLanguage/Extension:CodeMirror#Gadgets and user scripts|migration guide]] for more information. [https://phabricator.wikimedia.org/T373720]
* The MediaWiki Interfaces team is expanding coverage of REST API module definitions to include [[mw:Special:MyLanguage/API:REST API/Extensions|extension APIs]]. REST API modules are groups of related endpoints that can be independently managed and versioned. Modules now exist for [https://phabricator.wikimedia.org/T414470 GrowthExperiments] and [https://phabricator.wikimedia.org/T419053 Wikifunctions] APIs. As we migrate extension APIs to this structure, documentation will move out of the main MediaWiki OpenAPI spec and REST Sandbox view, and will instead be accessible via module-specific options in the dropdown on the [https://test.wikipedia.org/wiki/Special:RestSandbox REST Sandbox] (i.e., [[{{#Special:RestSandbox}}]], available on all wiki projects).
* The [[mw:Special:MyLanguage/Extension:Scribunto|Scribunto]] extension provides different pieces of information about the wiki where the module is being used via the [[mw:Special:MyLanguage/Extension:Scribunto/Lua reference manual|mw.site]] library. Starting last week, the library also provides a [[mw:Special:MyLanguage/Extension:Scribunto/Lua reference manual#mw.site.wikiId|way]] of accessing the [[mw:Special:MyLanguage/Manual:Wiki ID|wiki ID]] that can be used to facilitate cross-wiki module maintenance.

'''Weekly highlight'''
* Wikimedia site users can now log in without a password using passkeys. This is a secure method supported by fingerprint, facial recognition, or PIN. With this change, all users who opt for passwordless login will find it easier, faster, and more secure to log in to their accounts using any device. The new passkey login option currently appears as an autofill suggestion in the username field. An additional [[phab:T417120|&quot;Log in with passkey&quot; button]] will soon be available for users who have already registered a passkey. This update will improve security and user experience. The [[c:File:Passwordless_login_screencast.webm|screen recording]] demonstrates the passwordless login process step by step.
* [[m:Special:MyLanguage/Tech/Server switch|All wikis will be read-only]] for a few minutes on Wednesday, 25 March 2026 at [https://zonestamp.toolforge.org/1774450800 15:00 UTC]. This is for the datacenter server switchover backup tests, [[wikitech:Deployments/Yearly calendar|which happen twice a year]]. During the switchover, all Wikimedia website traffic is shifted from one primary data center to the backup data center to test availability and prevent service disruption even in emergencies.

'''Updates for editors'''
* Wikimedia site users can now export their notifications older than 5 years using a [[toolforge:echo-chamber|new Toolforge tool]]. This will ensure that users retain their important notifications and avoid them being lost based on the planned change to delete notifications older than 5 years, as previously announced. [https://phabricator.wikimedia.org/T383948]
* Wikipedia editors in Indonesian, Thai, Turkish, and Simple English now have access to Special:PersonalDashboard. This is an [[mw:Special:MyLanguage/Moderator Tools/Dashboard|early version of an experience]] that introduces newer editors to patrolling workflows, making it easier for them to move from making edits to participating in more advanced moderation work on their project. [https://phabricator.wikimedia.org/T402647]
* The [[Special:Block]] now has two minor interface changes. Administrators can now easily perform indefinite blocks through a dedicated radio button in the expiry section. Also, choosing an indefinite expiry provides a different set of common reasons to select from, which can be changed at: [[MediaWiki:Ipbreason-indef-dropdown]]. [https://phabricator.wikimedia.org/T401823]
* Mobile editors [[mw:Special:MyLanguage/Contributors/Account Creation Experiments#Logged-out|at several wikis]] can now see an improved logged-out edit warning, thanks to the recent updates from the Growth team. These changes released last week are part of ongoing efforts and tests to enhance [[mw:Special:MyLanguage/Contributors/Account Creation Experiments|account creation experience on mobile]] and then increase participation. [https://phabricator.wikimedia.org/T408484]

For example, the bug that prevented mobile web users from seeing the block information when affected by multiple blocks has been fixed. They can now see messages of all the blocks currently affecting them when they access Wikipedia.

'''Updates for technical contributors'''
* Images built using Toolforge will soon get the upgraded buildpacks version, bringing support for newer language versions and other upstream improvements and fixes. If you use Toolforge Build Service, review the recent [https://lists.wikimedia.org/hyperkitty/list/cloud-announce@lists.wikimedia.org/thread/EMYTA32EV2V5SQ2JIEOD2CL66YFIZEKV/ cloud-announce email] and update your build configuration as necessary to ensure your tools are compatible.

* The [https://api.wikimedia.org/wiki/Main_Page API Portal] documentation wiki will shut down in June 2026. API keys created on the API Portal will continue to work normally. api.wikimedia.org endpoints will be deprecated gradually starting in July 2026.

'''Weekly highlight'''
* The Beta version of [[abstract:|Abstract Wikipedia]] a new Wikimedia project which is language-independent, was launched last week. The project allows communities to build Wikipedia articles in their native language, which can be readily accessed by other users in their own languages. The wiki is powered by instructions from Wikifunctions and also based on structured content from Wikidata. [[:f:Special:MyLanguage/Wikifunctions:Status updates/2026-03-26|Read more]].

'''Updates for editors'''
* The Growth team is running an A/B test to evaluate a clearer, more user-friendly message that promotes account creation on wikis. Currently when logged-out mobile users begin editing, they see a jarring warning message that can feel abrupt and discouraging. This also presents temporary account editing as the default rather than encouraging account creation. The test is running on ten Wikipedias, including Arabic, French, Spanish and German. [[mw:Special:MyLanguage/Contributors/Account Creation Experiments#2. Improve logged-out warning message (T415160)|Read more]].
* The Wikimedia Apps team is inviting feedback on [[mw:Special:MyLanguage/Wikimedia Apps/Team/Future of Editing on the Mobile Apps|how editing should work on the Wikipedia mobile apps]]. The discussion focuses on improving how users access editing tools when they tap &quot;Edit&quot;. This is part of a broader effort to convert readers who develop an interest in editing, to access a more user-friendly pathway to start contributing.

'''Updates for editors'''

* The [[mw:Special:MyLanguage/Help:Extension:CampaignEvents|CampaignEvents extension]] now includes a new group goal-setting feature, enabling organizers to set and track event goals such as the number of articles created and participating contributors in real time. Similarly, participants can work toward shared targets and see their collective impact as the event unfolds. The feature is now available on all Wikimedia wikis. Learn more in [[mw:Special:MyLanguage/Help:Extension:CampaignEvents/Registration/Collaborative contributions#Goal setting|the documentation]].

'''Updates for technical contributors'''
* The [[m:Special:MyLanguage/WMDE Technical Wishes/Sub-referencing|sub-referencing feature]], which lets editors add details to an existing reference without duplicating it, will be gradually rolled out to [[phab:T414094|more wikis]] later this year. Wikis using the [[mw:Special:MyLanguage/Reference Tooltips|Reference Tooltips]] gadget are encouraged to update their version (typically at [[m:MediaWiki:Gadget-ReferenceTooltips.js|MediaWiki:Gadget-ReferenceTooltips.js]] as shown [https://en.wikipedia.org/w/index.php?diff=1344408362 here]) to ensure compatibility. Other reference-related gadgets may also be affected. [https://phabricator.wikimedia.org/T416304]
* All Wikinews editions will be closed and switched to read-only mode on 4 May 2026. Content will remain accessible, but no new edits or articles can be added. This closure was approved by the Board of Trustees of the Wikimedia Foundation following extended discussions. [[m:Wikimedia Foundation Board noticeboard#Board of Trustees Approves Closure of Wikinews|Read more]].
* The [[:mw:Special:MyLanguage/API:Action API|Action API]] has had several formats for requested output.

Check [[Special:ListGroupRights|Special:ListGroupRights]] for the status of your wiki. [https://phabricator.wikimedia.org/T248294]
* The Growth team has launched an [[mw:Special:MyLanguage/Contributors/Account_Creation_Experiments|account creation experiment]] to evaluate whether adding an account creation button to the mobile web header increases new account registrations and encourages more mobile users to contribute to the wikis. The experiment is currently live on Hindi, Indonesian, Bengali, Thai, and Hebrew Wikipedia, and targets 10% of logged-out mobile web users.

'''Updates for technical contributors'''
* Starting later this week, {{int:group-abusefilter}} who have the [[mw:Special:MyLanguage/Help:Extension:CodeMirror|{{int:codemirror-beta-feature-title}}]] beta feature enabled will have [[mw:Special:MyLanguage/Extension:CodeMirror|CodeMirror]] instead of [[mw:Special:MyLanguage/Extension:CodeEditor|CodeEditor]] as the editor at [[Special:AbuseFilter|Special:AbuseFilter]]. This is part of the broader effort to make the user experience more consistent across all editors. [https://phabricator.wikimedia.org/T399673][https://phabricator.wikimedia.org/T419332]
* Tools and bots that access the [[mw:Special:MyLanguage/Notifications/API|Notifications API]] (&lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;action=query&amp;meta=notifications&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt;) will need to update their OAuth or BotPassword grants to also include access to private notifications. [https://phabricator.wikimedia.org/T421991]
* Due to a library upgrade, listings on category pages may be displayed out of order starting on Monday, 20th April. A migration script will be run to correct this, and will take hours to days depending on the size of the wiki (up to a week for English Wikipedia). [https://phabricator.wikimedia.org/T422544]

'''Weekly highlight'''
* After two years of development, [[mw:Special:MyLanguage/Help:Extension:CodeMirror|{{int:codemirror-beta-feature-title}}]], also known as [[mw:Special:MyLanguage/Extension:CodeMirror|CodeMirror 6]], is to be promoted out of beta on Tuesday, April 21. It brings better code and wikitext readability, reduction in typing errors, and other [[mw:Special:MyLanguage/Help:Extension:CodeMirror|benefits]] to all users of the standard syntax highlighter. A huge thank you to volunteer [https://phabricator.wikimedia.org/p/Bhsd/ Bhsd] who developed many of the new features, including [[mw:Special:MyLanguage/Help:Extension:CodeMirror#Code folding|code folding]], [[mw:Special:MyLanguage/Help:Extension:CodeMirror#Autocompletion|autocompletion]], and [[mw:Special:MyLanguage/Help:Extension:CodeMirror#Linting|linting]].

'''Updates for editors'''
* [[mw:Special:MyLanguage/Readers/Reader Experience/WE3.3.4 Reading lists|Reading lists]] is a feature which allows readers to save articles to a list for reading later. This feature is now in beta on Arabic, French, Indonesian, Vietnamese, and Chinese Wikipedias and by default for all new accounts on all Wikipedias.
* An experiment which explores extending [[mw:Special:MyLanguage/Readers/Reader Growth/Mobile page previews|Page Previews to mobile web]] will be launched in the week of April 20 on Arabic, English, French, Italian, Polish, and Vietnamese Wikipedias. Page Previews are pop-ups that display a thumbnail, lead paragraph, and a link to open the full article of a blue link, thereby improving content discovery. The feature is already available on desktop and in the apps. [[m:Special:MyLanguage/List of experiments in Product and Technology#Template|Read more about this experiment and others]].
* On several wikis, logged-in editors who haven't [[mw:Special:MyLanguage/Help:Email confirmation|confirmed their email addresses]] can now see a banner encouraging them to do so. Having the email address confirmed allows a user to restore access to the account if they lose it.

[https://phabricator.wikimedia.org/T184857]

'''Updates for technical contributors'''
* As part of the promotion of [[mw:Special:MyLanguage/Help:Extension:CodeMirror|CodeMirror]] from a beta feature, all users will use [[mw:Special:MyLanguage/Extension:CodeMirror|CodeMirror]] instead of [[mw:Special:MyLanguage/Extension:CodeEditor|CodeEditor]] for syntax highlighting when editing JavaScript, CSS, JSON, Vue and Lua content pages. [https://phabricator.wikimedia.org/T419332]
* The &lt;code&gt;mirrors.wikimedia.org&lt;/code&gt; service for Debian and Ubuntu users will sunset and stop working on May 15. The resources for the service will be replaced with new and better options. Some users may need to switch to a different server which should take about a minute.

[https://phabricator.wikimedia.org/T28741]
* Following the recent implementation of global API rate limits on unidentified traffic, the Wikimedia Foundation will continue efforts to ensure [[mw:Special:MyLanguage/MediaWiki Product Insights/Responsible Reuse|fair use of infrastructure]] by applying global limits to identified API traffic beginning the last week of April. These limits are intentionally set as high as possible to minimise impact on the community. Bots running in Toolforge/WMCS or with the bot user right on any wiki should not be affected for now. However, all developers are advised to follow updated best practices. For more information, see [[mw:Special:MyLanguage/Wikimedia APIs/Rate limits|Wikimedia APIs/Rate limits]] and [[mw:Special:MyLanguage/Wikimedia APIs/Rate limits/FAQ|Frequently Asked Questions]].
* The [[mw:Special:MyLanguage/Attribution API|Attribution API]] is now available as a [[mw:Special:MyLanguage/Wikimedia APIs/Stability policy|beta]]. The API fetches information for crediting Wikimedia articles and media files wherever they are used. Reference documentation is available through the REST Sandbox special page available on all Wikimedia wikis (such as the [https://en.wikipedia.org/w/index.php?api=attribution.v0-beta&amp;title=Special%3ARestSandbox REST sandbox on English Wikipedia]). Share your feedback on the [[mw:Talk:Attribution API|project talk page]].
* There is no new MediaWiki version this week.

'''Updates for editors'''
* There is a change in how new users are autoconfirmed that will improve anti-vandalism protection. Currently, users who have had an account for a few days and made a few edits are automatically added to the [[{{int:grouppage-autoconfirmed/{{CONTENTLANGUAGE}}}}|{{int:group-autoconfirmed}}]] group. This configuration tends to be exploited by some vandals, who create accounts and start to use them only after some time. To mitigate this, the configuration will be updated next week so that – for the purpose of becoming autoconfirmed – the account age will be counted from their first edit, instead of registration date. The numeric value of the age threshold will remain the same. This change will be deployed only to wikis which require at least one edit as part of the autoconfirmation conditions. [https://phabricator.wikimedia.org/T418484]
* All Wikipedia users with new accounts and those who activated the &quot;automatically enable most beta features&quot; option in their preference can now use the [[mw:Special:MyLanguage/Readers/Reader Experience/WE3.3.4 Reading lists|reading lists]] beta feature to save articles for later reading. This helps organize reading interests in one place for convenient access.

'''Updates for technical contributors'''
* As a reminder, the global API rate limits will be applied this week to identified API traffic. This is to help ensure [[mw:MediaWiki Product Insights/Responsible Reuse|fair use of infrastructure]]. Bots running in Toolforge/WMCS or with the bot user right on any wiki should not be affected for now. However, all developers are advised to follow updated best practices.

'''Weekly highlight'''
* The [[mw:Special:MyLanguage/Article guidance|Article guidance]] team invites experienced editors of [[mw:Special:MyLanguage/Article guidance/Pilot wikis and collaborators|pilot Wikipedias]]—Arabic, Bangla, Japanese, Portuguese, Persian, Turkish, Simple English, Spanish, and French—to help translate and adapt [https://b24e11a4f1.catalyst.wmcloud.org/wiki/Category:Pages_using_article_guidance sample outlines]. These outlines will guide editors in creating clear, well-structured, and policy-compliant articles when using [https://b24e11a4f1.catalyst.wmcloud.org/wiki/Special:NewArticle the feature] once it is launched in May 2026. [[mw:Special:MyLanguage/Article guidance#Adapting a sample outline in a Wikipedia|Simple instructions]] on how to translate and adapt the outlines are available.
'''Updates for editors'''
* The [[:m:Special:MyLanguage/Product and Technology Advisory Council|Product and Technology Advisory Council]] has published [[:m:Special:MyLanguage/Product and Technology Advisory Council/May 2026 draft PTAC recommendation for feedback|draft recommendations]] on a model that affiliates can follow when contributing to the technical space. Community members are invited to provide feedback on the recommendation until May 8th [[:m:Talk:Product and Technology Advisory Council/May 2026 draft PTAC recommendation for feedback|on the talk page]].
* The number of available thumbnail size preferences in MediaWiki is being reduced to three standardized options—Small (180px), Regular (250px), and Large (400px), as part of ongoing efforts to improve performance and reduce strain on thumbnail services. As a result, existing preferences will be mapped to the nearest new size (for example, smaller selections like 120px or 150px will render at 180px, while larger ones like 300px or 360px will render at 400px). The preferences interface will soon be updated to reflect these changes, and users who wish to opt out or provide feedback can do so. [https://phabricator.wikimedia.org/T424909]
* From now on, even when a permission expires automatically, users will receive an Echo notification similar to the standard notification for permission changes. There is a difference between this and [[m:Special:MyLanguage/Global reminder bot|Global reminder bot]] in that the latter reminds users a week ''before'' the rights are due to expire, so that they can renew the rights.

For example, the problem where the ULS language selector in [[m:Special:Translate|Special:Translate]] would scroll vertically when it shouldn't, has been resolved. Previously, when users opened the &quot;Translate to English&quot; dropdown and typed certain inputs, the dialog would scroll vertically by a few pixels even when there was enough space to display all results. The dropdown no longer shifts unnecessarily when filtering languages. [https://phabricator.wikimedia.org/T358864] 
* The [[m:Special:GlobalWatchlist|Global Watchlist]], which lets you view your watchlists from multiple wikis on a single page, continues to improve. For example, watchlists for Wikibase sites such as [[:d:|Wikidata]] now support [[mw:Special:MyLanguage/Extension:EntitySchema|EntitySchema]] elements for better tracking. The Live Updates mode now refreshes the special page every 60 seconds to comply with the updated [[mw:Special:MyLanguage/Wikimedia APIs/Rate limits|global API rate limits]] for improved real-time responsiveness. Additionally, a directionality bug that displayed links as &quot;changes 3&quot; instead of &quot;3 changes&quot; in mixed-direction lists has been fixed.

'''Updates for technical contributors'''
* The second phase of [[mw:Special:MyLanguage/Wikimedia APIs/Rate limits|global API rate limits]] has been rolled out to reduce the [[diffblog:2026/03/26/quo-vadis-crawlers-progress-and-whats-next-on-safeguarding-our-infrastructure/|impact of AI crawlers]] and ensure fair, sustainable access to Wikimedia resources, prioritising human and mission-aligned traffic. [[mw:Special:MyLanguage/Wikimedia APIs/Rate limits#Limits|Limits]] have been shifted from per-hour to per-minute, producing smoother traffic patterns and more predictable API load. Community users are not expected to be affected, and no action is required. Early indications show some User-Agent-based requestors are adjusting behaviour, and around 64% of automated API traffic has been identified. Monitoring continues, and Wikimedia Enterprise remains available for commercial support.

'''Updates for editors'''
* The Reader Growth team is launching an experiment to test a new [[mw:Special:MyLanguage/Readers/Reader_Growth/Share_Card|Share Card feature]] that allows readers to create visually engaging cards from Wikipedia articles or selected article sections and share them online, with each card linking back to the original article to help expand readership and article discovery. The mobile-only A/B test will be available to a portion of readers on Arabic, Chinese, French, Vietnamese, and English Wikipedia to better understand reading and sharing habits, and is scheduled to begin the week of May 18 and run for four weeks.
* The Android and iOS Wikipedia apps recently released the [[mw:Special:MyLanguage/Wikimedia_Apps/Team/25th_Birthday_Reading_Challenge|25-day reading challenge]] into Beta, as part of efforts to drive reader engagement by encouraging users to complete reading milestones. To track their reading streak during the challenge, App users can add a widget featuring Baby Globe to their home screen. The challenge officially begins May 11.

* An experiment to show [[mw:Special:MyLanguage/Readers/Reader Experience/Reading lists|Reading Lists]] to logged-out readers on mobile web will launch on May 18 across German, Spanish, Italian, Portuguese, Polish, Dutch, Turkish, and Urdu Wikipedias, and will run for one month. The effort supports broader goals of helping readers save and organize articles for later reading, while encouraging habits that could lead to future Wikipedia contributions.
* To support a bookmark button in the Reading List beta feature, the &quot;Tools &gt; Action&quot; menu has been updated to display icons, including the watch star indicator that helps editors identify temporarily watched articles. The icons now also match those used on mobile, improving consistency across platforms. The change is currently limited to the actions menu and mainly affects editors with privileged user rights.

* [[mw:Special:MyLanguage/VisualEditor/Suggestion Mode|Suggestion Mode]] was released as an [[w:en:A/B test|A/B test]] for newcomer editors on the mobile website at [[phab:T421189|~15 Wikipedias]]. The experiment will measure the impact that Suggestion Mode has on the proportion of newcomer mobile web edit sessions that result in constructive (un-reverted) article edits.

'''In depth'''

* On English, French, Japanese, and a few other Wikipedias, there was a [[diffblog:2025/09/02/better-detecting-bots-and-replacing-our-captcha/|trial of hCaptcha]], a third-party bot detection service. The trial showed that hCaptcha effectively detects and deters some bad-faith automated activity, on its own and by giving [[w:en:Wikipedia:Village pump (technical)/Archive 225#Introducing SuggestedInvestigations|checkusers and stewards]] signals to look into. Because the results were positive, hCaptcha will be rolled out across all wikis over the next few weeks. [[mw:Special:MyLanguage/Product Safety and Integrity/Anti-abuse signals/hCaptcha|See the hCaptcha project page]] for technical information about the implementation and privacy protections.

* The latest Community Tech update is now available, with progress across several Community Wishlist initiatives, including Reading Lists expansion from the mobile app to the website, new language support for &quot;Who Wrote That&quot; and the Personal Dashboard, improvements to 3D rendering and Charts, and upcoming work on talk page sorting, audio playback, and editing workflows. The update also shares current priorities, wishlist status trends, and opportunities for community feedback on future focus areas and the Wikimedia Foundation’s 2026–2027 Annual Plan.

'''Weekly highlight'''
* Following a [[mw:Special:MyLanguage/Contributors/Account Creation Experiments#LOWM|successful account creation experiment]], an improved logged-out edit warning message will be deployed to all Wikimedia wikis in the first week of June. The change will only affect logged-out users on mobile web who open an editing session. The updated experience is designed to encourage account creation more clearly, while still allowing users to edit with temporary accounts. Results from the experiment showed a significant increase in account creation, with a 27% relative lift among users shown the updated message. As expected, as more people funnel into account creation, temporary accounts decreased by a relative 16%. The experiment did not show any significant changes in constructive edit rates or other monitored contributor metrics. [https://phabricator.wikimedia.org/T424595] 

'''Updates for editors'''
* For security reasons, members of certain user groups are [[m:Special:MyLanguage/Mandatory two-factor authentication for users with some extended rights|required to have two-factor authentication]] (2FA) enabled. Members of these groups will be unable to disable the last 2FA method on their account, and it will be impossible to add users without 2FA to these groups. Users will still be able to add new authentication methods or remove them, as long as at least one method is continuously enabled. In the next few weeks, users without 2FA will be removed from these groups. Notably, this applies to bureaucrats. See the linked tasks for deployment schedules. [https://phabricator.wikimedia.org/T423119][https://phabricator.wikimedia.org/T423120]
* [[m:Special:MyLanguage/WMDE Technical Wishes|WMDE Technical Wishes]] will run an [[w:en:A/B testing|A/B test]] on [[:phab:T415904|10 wikis]], testing [[m:WMDE Technical Wishes/References/Reference Previews|potential improvements for Reference Previews]]. The experiment will run for ~2 weeks at the end of May / beginning of June and will affect 10% of desktop readers on the participating wikis.
* After two successful experiments, the Reader Growth team is rolling out an [[mw:Special:MyLanguage/Readers/Reader Growth/Image Browsing|Image Browsing]] beta feature for all Wikipedias on mobile on May 25. This means that anyone who has all beta features on by default will start to see this feature, and others can check the box to turn it on in their preferences. The beta feature will include a carousel of all an article's images at the top of the article, with controls for editors to [[mw:Readers/Reader_Growth/Image_Browsing#Phase_2.1_beta_feature|exclude images from the article's carousel or to exclude an article from the feature entirely]].

Projects relying on these classes are encouraged to review related usage and plan for migration. Please note that &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;floatleft&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; and &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;floatright&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; may also be deprecated in future, although there are currently no plans to do so.

* The [[mw:Special:MyLanguage/Readers/Reader Experience|Reader Experience team]] is conducting an experiment to show the [[mw:Special:MyLanguage/Readers/Reader Experience/Reading lists|reading lists]] feature, which is still in development, to logged-out mobile readers to test whether it encourages account creation at a higher rate compared to the watchstar button. The [[mw:Special:MyLanguage/Readers/Reader Experience/Reading lists#Experiment timeline|experiment]] was launched on May 18th on German, Spanish, Italian, Portuguese, Polish, Dutch, Turkish, and Urdu wikis, and it will run for a month.
* The Wikimedia Apps team released [[mw:Special:MyLanguage/Wikimedia Apps/Team/Explore Feed Refresh/Phase 1|Phase 1]] of the redesigned Home Feed to the Android Beta app. The new Home Feed includes a refreshed &quot;Community&quot; tab and a personalized &quot;For You&quot; tab featuring daily updated reading recommendations.

'''Weekly highlight'''
* Wikimedia Enterprise has increased the free usage limits for its API offerings. The monthly request limit for the On-demand API has increased from 5,000 to 50,000 requests, while the Snapshot API limit has increased from 15 to 30 requests per month. In addition, Structured Contents snapshots are now available for free accounts. These changes expand access to Wikimedia Enterprise data for developers, researchers, and organizations using Wikimedia content. [https://enterprise.wikimedia.com/blog/enhanced-free-api]

'''Updates for editors'''
* The [[mw:Special:MyLanguage/Wikimedia_Apps/Team/Explore Feed Refresh/Phase 1|refreshed Explore Feed]], now called the Home Feed, is rolling out to 50% of users of the Wikipedia Android app. The Home Feed helps readers discover relevant content through two new tabs: ''Community'' and ''For You''. The Community tab provides a scrollable feed of curated content and updates from the broader Wikimedia community and movement, while the ''For You'' tab offers a full-screen, swipeable experience that shows content tailored to a user's interests. The redesign is part of a broader effort to improve discovery and enhance the learning experience in the Wikipedia app.
* The [[mw:Special:MyLanguage/Wikimedia Apps/Team/iOS/&quot;Which came first?&quot; Game|Which came first?]] daily trivia game is now available in the beta version of the Wikipedia iOS app in English, German, French, Portuguese, Russian, Spanish, Arabic, Chinese, and Turkish. The game uses historical events from Wikipedia's &quot;On This Day&quot; content and challenges readers to guess which of two events happened first. The game was previously released on Android. Communities interested in making the game available in their languages can [[mw:Special:MyLanguage/Wikimedia_Apps/Team/Games#Game availability by language|read the instructions and requirements]].
* [[m:Special:MyLanguage/WMDE Technical Wishes/Sub-referencing|Sub-referencing]], a new MediaWiki feature that allows editors to reuse references with different details, will begin rolling out to Wikimedia wikis following a successful pilot phase. Deployment will start on 8 June for most [[wikitech:Deployments/Train#Wednesday|Group 1 wikis]] and French Wikipedia, with additional Wikipedia language editions receiving the feature over the coming months. Communities are encouraged to prepare by checking for [https://translatewiki.net/w/i.php?title=Special%3ATranslate&amp;group=ext-cite&amp;language=en&amp;action_source=search&amp;filter=%21translated&amp;optional=1&amp;action=translate untranslated Cite extension messages] in their language and reviewing any use of [[mw:Special:MyLanguage/Reference Tooltips|Reference Tooltips]], which may require [[:phab:T416304#11668731|updates]] to support the new functionality. Wikis using [[mw:Special:MyLanguage/Help:Reference Previews|Reference Previews]] do not need to take any action. Communities may also wish to create the ''cite-tracking-category-ref-details'' [[Special:TrackingCategories|tracking category]] as a hidden category using &lt;code&gt;&lt;nowiki&gt;__HIDDENCAT__&lt;/nowiki&gt;&lt;/code&gt; (or a dedicated template), and connect it to the corresponding Wikidata item [[d:Q129764848]]. [https://phabricator.wikimedia.org/T425662]
* The [[mw:Special:MyLanguage/Readers/Reader Growth/Mobile page previews#Experimentation|Page Previews experiment]] on mobile web has concluded. The team decided not to roll out the feature after the results showed no statistically significant impact on reader retention, as the primary success metric was retention improvement. Page Previews, which are already available on desktop and in the apps, display a thumbnail, lead paragraph, and link to the full article when readers tap a blue link. The experiment tested this experience on mobile web across six Wikipedias.
* The [[mw:Special:MyLanguage/Codex/Design/Icons|user interface icon library]] will be [[phab:T399175|updated later this week or next week]]. Most of the ~300 icons have been slightly refined and ~30 new icons have been added. These changes improve the icons to make them more consistent and comprehensible, and provide more visual balance when they are used in groups.
* The [[mw:Special:MyLanguage/Universal Language Selector|Universal Language Selector]] (ULS) interface in MediaWiki, which helps users select content in other languages, has been updated. The new version improves speed and accessibility, and users of Wikimedia projects can now pin languages for quicker language switching. The deployment to Wikimedia sites will happen gradually in the coming weeks. You can test it now as a beta feature by selecting [[Special:Preferences#mw-prefsection-betafeatures|beta features]] in your profile preferences and share your feedback on [[mw:Special:MyLanguage/Universal Language Selector/New ULS|the project page]].

* The function signature for &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;mw.util.addPortletLink()&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; has been simplified. Developers can now pass a configuration object instead of a list of positional parameters when creating portlet links. The previous function signature remains supported for backwards compatibility. For example, instead of: &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;mw.util.addPortletLink('p-cactions', '#', 'Stub', 'ca-stubtag', 'Add a stub tag to this page');&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; use &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;mw.util.addPortletLink('p-cactions', { href: '#', text: 'Stub', id: 'ca-stubtag', tooltip: 'Add a stub tag to this page' });&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt;. Script maintainers are encouraged to review existing uses of &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;addPortletLink()&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; and update them where appropriate. This change will be available on all wikis from 11 June. Thanks to community volunteer Gerges for contributing this improvement. [https://phabricator.wikimedia.org/T427945]

'''Weekly highlight'''
* The [[mw:Special:MyLanguage/Readers/Reader Growth|Reader Growth team]] has launched an [[mw:Special:MyLanguage/Readers/Reader Growth/Image Browsing|Image Browsing]] beta feature on the mobile web version of all Wikipedias. The feature shows an image carousel at the top of articles with 3 or more images. Editors can configure this feature with the following controls: to hide a specific image from a page, either use &lt;code&gt;class=notpageimage&lt;/code&gt; excluding it from thumbnail previews, or &lt;code&gt;class=noviewer&lt;/code&gt; excluding it from MediaViewer. The carousel can also be disabled from a page entirely, with the magic word &lt;code&gt;&lt;nowiki&gt;__NOMEDIAVIEWERCAROUSEL__&lt;/nowiki&gt;&lt;/code&gt;. To submit feedback or flag bugs, please visit the [[mw:Talk:Readers/Reader Growth/Image Browsing|project page]]. 
* [[mw:Special:MyLanguage/Help:Tables#class=&quot;wikitable&quot;|Wikitables]] can now be [[mw:Special:MyLanguage/Help:Sortable tables#Forcing the initial sort direction|sorted in descending order]] on the first click by adding &lt;code dir=ltr&gt;data-sort-order=&quot;desc&quot;&lt;/code&gt; to the header cell. Previously, by default, clicking a column header for the first time sorts it in ascending order. This addition to a Wikitable gives it more control and flexibility, while the default behavior for subsequent clicks remains unchanged. [https://phabricator.wikimedia.org/T398416]

'''Updates for editors'''
* The [[mw:Special:MyLanguage/Article guidance|Article guidance]] feature is currently being tested with some editors creating new articles on the Simple English, French, and Turkish Wikipedias. The experiment will soon begin on the Arabic and Bangla Wikipedias as well. [[w:simple:Special:NewArticle|This feature]] gives editors community-curated guidance to help them create articles that follow community standards. Experienced editors can continue creating or adapting outlines for specific article types that are commonly created by less experienced contributors. The outlines guide less experienced editors in creating high-quality articles. A quick guide to markups used in outlines can be found on [[mw:Special:MyLanguage/Article guidance/Test feature guide#Markups in outlines|this page]]. [[w:simple:Wikipedia:Article Guidance|Example outlines]] that can be adapted and instructions for how to adapt them are on [[mw:Special:MyLanguage/Article guidance#Adapting a sample outline in a Wikipedia|this section]] of the project page.
* Wikis that wish to replace the &quot;indefinitely&quot; button in Special:Block for temporary accounts (for example, wikis that block temporary users only until account expiration) will be able to do so by creating [[MediaWiki:ipb-indefinite-expiry-temporary-account]] with the block duration they want.

'''Updates for technical contributors'''
* By the end of June, a valid user-agent string will be required for automated dumps downloads from the dumps.wikimedia.org website. Automated requests that provide a generic or empty user-agent will be blocked. This [[phab:T400119|extends enforcement]] of the long standing [[foundation:Special:MyLanguage/Policy:Wikimedia Foundation User-Agent Policy|user-agent policy]]. Access to dumps through Wikimedia Cloud Services will not change.
* The roll out of global [[mw:Wikimedia APIs/Rate limits|API rate limits]] is now complete, with limits enforced across all APIs and at the documented levels for all groups. Bots running in Toolforge/WMCS or with the bot user right on any wiki remain exempt. All bots should continue to follow the documented best practices to avoid being rate limited.
* The [https://api.wikimedia.org/wiki/Main_Page API Portal wiki] will be read only starting this week (June 15-18). The following week (June 22-25), all API Portal wiki URLs will redirect to [[mw:Wikimedia APIs|Wikimedia APIs on mediawiki.org]]. Learn more on the [[wikitech:API Portal/Deprecation|project page]].

This update enables access to Mentorship ([[mw:Special:MyLanguage/Help:Growth/Mentorship|if configured]]), Impact module, the Help Panel, and a simplified Newcomer Homepage (without Suggested Edits). Wikidata administrators are still configuring the features through Community Configuration.

'''Updates for editors'''
* The special page [[{{#special:RangeCalculator}}]] has been created. It allows users to find an IP range without needing to rely on external tools. Until now, this tool was only available to CheckUsers. [https://phabricator.wikimedia.org/T268429]
* [[m:Special:MyLanguage/WMDE Technical Wishes/Sub-referencing|Sub-referencing]] is a new MediaWiki feature that allows editors to reuse references with different details. It will be deployed to most small and medium-sized Wikipedia language versions on June 23. The [[m:Special:MyLanguage/WMDE Technical Wishes/Sub-referencing#deployment|FAQ]] lists possible actions to take on your wiki to support the deployment. Check the [[:phab:T414094|rollout plan]] for the next deployment steps. [https://phabricator.wikimedia.org/T428902]
* Starting next week, users will get a notification when they are blocked or unblocked from editing, or if this block changes. [https://phabricator.wikimedia.org/T100974]
* [[File:Reload icon with two arrows.svg|12px|link=|class=skin-invert|Recurrent item]] View all {{formatnum:32}} community-submitted {{PLURAL:32|task|tasks}} that were [[m:Special:MyLanguage/Tech/News/Recently resolved community tasks|resolved last week]].

'''Updates for technical contributors'''
* Starting next week, abuse filters that are set to &quot;require CAPTCHA verification&quot; will begin to also affect users with the &lt;code&gt;skipcaptcha&lt;/code&gt; right, which includes most autoconfirmed users. Bots are exempted. This change only affects edits that trigger an abuse filter. The &lt;code&gt;skipcaptcha&lt;/code&gt; right will continue to exempt users from having to solve CAPTCHAs in the ordinary course of using the wikis. [https://phabricator.wikimedia.org/T402595]
* Reference documentation for the [[wikitech:Machine_Learning/LiftWing/API|Lift Wing API]] has moved from the API Portal to the interactive [https://wikitech.wikimedia.org/w/index.php?api=lift-wing&amp;title=Special%3ARestSandbox REST Sandbox].
* The API Portal wiki is now closed. For API documentation, see [[mw:Special:MyLanguage/Wikimedia_APIs|Wikimedia APIs on mediawiki.org]]. All API Portal wiki URLs (https://api.wikimedia.org/wiki/) will redirect to the mediawiki.org page starting June 22. [https://phabricator.wikimedia.org/T427537]
* [[File:Reload icon with two arrows.svg|12px|link=|class=skin-invert|Recurrent item]] Detailed code updates later this week: [[mw:MediaWiki 1.47/wmf.8|MediaWiki]]

'''Meetings and events'''
* Join an online call on 25 June at 2:30pm UTC to meet the current Wikimedia interns for [[mw:Google_Summer_of_Code/2026|Google Summer of Code]] and [[mw:Outreachy/Round_32|Outreachy]].

'''Updates for editors'''
* As part of the [[mw:Special:MyLanguage/Contributors/Account Creation Experiments|Account Creation Experiments]], the Growth team tested adding a user account icon in the mobile web header for logged-out users, providing direct access to &quot;Create account&quot; and &quot;Log in&quot; actions. The experiment increased account creation by about 20% without negatively affecting edit quality or constructive edit rates. The feature will now be rolled out to all Wikimedia Foundation wikis on mobile web in the first week of July. [https://phabricator.wikimedia.org/T428220]
* After a [[phab:T426248|successful experiment]], logged-in users who did not [[mw:Special:MyLanguage/Help:Email_confirmation|confirm their email address]] when their account was created see a new banner asking them to complete that process. This helps reduce the risk that users get locked out of their account, and makes account email addresses overall more reliable. This is part of the [[mw:Special:MyLanguage/Product Safety and Integrity/Account Security|Account Security]] project. [https://phabricator.wikimedia.org/T428292]
* An update to [[Special:Search|Search]] is refining how the &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;-prefix:&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; behaves when used to exclude results. Previously, using &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;-prefix:&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; with negation could unintentionally broaden search results by adding the namespaces included in the search scope, leading to confusing behavior for users expecting a straightforward exclusion filter. With the update, &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;-prefix:&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; will now strictly exclude matching page titles as intended and may display a warning if the relevant namespace has not been explicitly selected. The behavior of &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;prefix:&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; without negation however remains unchanged. [https://phabricator.wikimedia.org/T427443]
* [[File:Reload icon with two arrows.svg|12px|link=|class=skin-invert|Recurrent item]] View all {{formatnum:33}} community-submitted {{PLURAL:33|task|tasks}} that were [[m:Special:MyLanguage/Tech/News/Recently resolved community tasks|resolved last week]]. For example, an issue where reviewers using the Page Curation toolbar were not automatically subscribed to talk page discussions they started has now been fixed. Reviewers will now receive notifications when someone replies to those discussions. [https://phabricator.wikimedia.org/T329346]

'''Updates for technical contributors'''
* Starting June 29th, automated downloads from the dumps.wikimedia.org website will be subject to the [[Foundation:Special:MyLanguage/Policy:Wikimedia Foundation User-Agent Policy|user-agent policy]]. Automated requests that provide a generic or empty user-agent will be blocked. Access to dumps through Wikimedia Cloud Services remains unaffected.

'''Updates for technical contributors'''
* In preparation for [[m:Special:MyLanguage/Event:Celebrate Women|Celebrate Women campaign]] planned for March 2027, the Wikimedia Foundation’s [[m:Special:MyLanguage/Wikimedia Foundation/Advancement/Community Growth/Content Enablement|Content Enablement team]] has launched a 22-question survey to better understand technical contributions by women+ (anyone who identifies as a woman) across Wikimedia projects. The survey takes approximately 15–20 minutes to complete and will remain open until 20 July 2026. The [[m:Special:MyLanguage/Celebrate Women/Technical contributions survey|questions]] are also available on-wiki for review in advance.
* The [[mw:Special:MyLanguage/Extension:Score|Score extension]] now supports rendering music scores as SVG images in addition to PNG, addressing a long-standing [[:phab:T49578|feature request]] and resolving historical image quality issues. Both formats are now provided to clients, with PNG in the &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;src&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; attribute and SVG in the &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;srcset&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; attribute.
* The new [[wikitech:Parsoid|Parsoid]] parser [[mw:Special:MyLanguage/Parsoid/Parser_Unification/Updates|continues to be deployed to additional wikis]], making it easier to introduce new reading and editing features. It was enabled on French Wikipedia, bringing total progress to covering 78.9% of Wikipedia page views. Rollout to English Wikipedia desktop will progress through this week.

'''Updates for editors'''
* [[mw:Special:MyLanguage/Growth/Revise_Tone|Revise Tone]] helps newcomers identify passages in Wikipedia articles that may contain non-encyclopedic language and encourages them to consider revising the tone. The feature was [[w:en:A/B_testing|A/B tested]] on the Arabic, English, French, and Portuguese Wikipedias, where newcomer task completion rates [[mw:Special:MyLanguage/Growth/Revise_Tone#Experiment_Results|increased by 38.7%]] compared to the default Copyedit task, with no decrease in edit quality. The test ended on July 9, and the feature is now available for everyone on these wikis, configurable via Community Configuration. [[phab:T426364|The plan]] is to release Revise Tone to more wikis.
* The community configuration that allows [[mw:Special:MyLanguage/Help:Growth/Mentorship#Automated mentor list cleanup|automatic removal of inactive mentors]] based on configurable criteria will be enabled on Thursday 16, [[mw:Special:MyLanguage/Growth/Deployment|on some wikis]] to keep mentor lists up to date. Mentors are experienced contributors who opt in to help new users on-wiki through the [[mw:Special:MyLanguage/Growth/Feature summary|Growth Features]]. Administrators can now prepare the settings via [[w:Special:CommunityConfiguration/Mentorship|Special:CommunityConfiguration/Mentorship]]; they will take effect starting Thursday.
* [[File:Reload icon with two arrows.svg|12px|link=|class=skin-invert|Recurrent item]] View all {{formatnum:38}} community-submitted {{PLURAL:38|task|tasks}} that were [[m:Special:MyLanguage/Tech/News/Recently resolved community tasks|resolved last week]]. For example, an issue where some users of the Wikipedia Android app were logged out immediately after signing in, preventing them from staying logged in and editing pages, has now been fixed. [https://phabricator.wikimedia.org/T316916]

'''Updates for technical contributors'''
* Editing a page via user scripts or gadgets was causing watchlist labels that the user had assigned to that page to reset. This has now been fixed. [https://phabricator.wikimedia.org/T423778]
* To work around a Safari bug (see [[phab:T425211]]), on Parsoid-enabled wikis, wikilink hrefs now use absolute urls instead of protocol-relative urls. REST API output remains unchanged and continue to use protocol-relative urls. Gadgets, user scripts, bots, and CSS might need to be adapted if they relied on the presence of protocol-relative urls in wikilink hrefs. [https://phabricator.wikimedia.org/T431358]

* The Wikimedia Foundation’s Experiment Platform Team has published a blog post reflecting on its first year of structured experimentation. It highlights successful experiments such as Paste Check, Reference Check, and Tone Check, which improved editing outcomes and have been rolled out to more users, as well as experiments that did not lead to product changes.

'''Updates for editors'''
* [[File:Maki-gift-15.svg|12px|link=|class=skin-invert|Wishlist item]] [[mw:Special:MyLanguage/ContentTranslation|Content Translation]] now supports dark mode, fulfilling a [[m:Community Wishlist/W544|Community Wishlist request]]. This brings the tool in line with the accessibility features available in the Vector 2022 and Minerva skins, helping reduce visual fatigue for users translating content. [https://phabricator.wikimedia.org/T367077]
* DiscussionTools' source mode and the 2017 wikitext editor will now offer autocomplete for links (&lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;[[&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt;), templates (&lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;{{&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt;), HTML and parser tags (&lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;&lt;&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt;), and magic words (&lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;__&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt;), making it quicker and easier to insert links, templates, and other wiki markup while editing. [https://phabricator.wikimedia.org/T432400]
* The [[mw:Special:MyLanguage/Readers/Reader Growth/Mobile page previews|Readers Growth team]] has concluded its experiment with mobile page previews and will not roll out the feature. Page Previews are a pop-up bottom sheet that appears when readers tap a blue link, showing a thumbnail, lead paragraph, and an option to open the article. The experiment showed flat retention and negative indicator metrics, suggesting that mobile web readers preferred navigating directly to linked articles rather than using page previews.
* The Reader Experience team has seen encouraging early results from the [[mw:Special:MyLanguage/Readers/Reader Experience/Reading lists|Reading Lists feature]], with 93% of participating users reporting that it was useful. Reading Lists help active readers save articles for future reading and support their learning goals on Wikimedia projects. The team plans further improvements before expanding the feature to more users.
* The [[mw:Special:MyLanguage/Wikimedia Apps/Team/Explore Feed Refresh|Explore Feed Refresh]] initiative was tested with new and casual Wikipedia app readers. The refreshed feed helps readers discover new and relevant content. After a 10.5% increase in engagement with the feed, Wikimedia Apps team has decided to scale the Home Feed redesign to iOS with the learnings from the Android release applied.
* [[File:Reload icon with two arrows.svg|12px|link=|class=skin-invert|Recurrent item]] View all {{formatnum:23}} community-submitted {{PLURAL:23|task|tasks}} that were [[m:Special:MyLanguage/Tech/News/Recently resolved community tasks|resolved last week]]. For example, an issue where subject names in the Article Guidance feature were displayed with incorrect capitalization on French Wikipedia, has now been fixed. Subject names will now follow the correct capitalization rules for the language. [https://phabricator.wikimedia.org/T427201]

'''Updates for technical contributors'''
* After running several [[mw:Special:MyLanguage/Contributors/Account Creation Experiments|Account Creation Experiments]] to improve registration completion rates, a new version of the username field on [[Special:CreateAccount|Create Account]] has been rolled out. It includes [[:c:File:Create account - July 2026 updates.png|a popover summarizing the username policy]] to provide clearer guidance during account creation. As part of this change, the messages &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;createacct-helpusername&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; and &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;createacct-username-help&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt; that several communities have configured will no longer be used. If communities want to customize the guidance shown in the new popover, they can instead edit the following messages: &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;createacct-username-policy-popover-bullet1&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt;, &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;createacct-username-policy-popover-bullet2&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt;, and &lt;bdi lang=&quot;zxx&quot; dir=&quot;ltr&quot;&gt;&lt;code&gt;&lt;nowiki&gt;createacct-username-policy-popover-bullet3&lt;/nowiki&gt;&lt;/code&gt;&lt;/bdi&gt;. [https://phabricator.wikimedia.org/T430604]
* Later this week, the [[mw:Special:MyLanguage/Help:Extension:CodeMirror|CodeMirror syntax highlighter]] will offer [[w:en:Theme (computing)|themes]]. The themes can be picked from a dropdown menu in the full [[mw:Special:MyLanguage/Help:Extension:CodeMirror#CodeMirror preferences|CodeMirror preferences]] dialog. For wikitext, available themes are default, colorblind-friendly (previously the colorblind preference option on [[Special:Preferences#mw-prefsection-editing]]) and no-highlighting. For code languages (i.e., CSS/JavaScript/JSON/Vue/Lua), there are several themes available. These same themes will eventually be available for wikitext, too. [https://phabricator.wikimedia.org/T163533]
* From now on, wikis can restrict editing in the &quot;User&quot; namespace to only the page owner and certain user groups. [[mw:Special:MyLanguage/Manual:$wgRestrictUserPageEditing|Read the configuration documentation]] to learn more.

'''Updates for editors'''
* The [[mw:Special:MyLanguage/Readers/Reader Experience|Reader Experience team]] has developed a [https://82db7c8d4b.catalyst.wmcloud.org/w/index.php?title=Regent%27s_Park&amp;uselang=de patch demo] that wraps the page toolbar onto two lines when there is not enough horizontal space for all the buttons. This aims to reduce crowding in the Vector 2022 toolbar, which can occur on some language Wikipedias at certain screen widths. [https://phabricator.wikimedia.org/T429518]
* The Reader Experience team is planning to launch [[mw:Special:MyLanguage/Readers/Reader Experience/Reading lists|Reading Lists]], a [[m:Special:MyLanguage/Community Wishlist Survey 2021/Mobile and apps/Have Apps reading lists available on Destop/Mobile|Community Wishlist item]], which is currently available to try in beta, as a full feature in September. Before then, volunteer translator help is needed for [https://translatewiki.net/w/i.php?title=Special%3ATranslate&amp;group=ext-readinglists&amp;filter=&amp;action=translate string translations] into a number of languages. The feature supports reading and learning goals on Wikipedia.
* Next week, the table of contents on Wikimedia Commons file pages will be improved by consolidating the file page table of contents with the page table of contents. This will make it easier to understand a file page’s structure, navigate to specific sections, and share links to individual sections. [https://phabricator.wikimedia.org/T332644]

'''Updates for technical contributors'''
* The variable and function selector in AbuseFilter has been updated to support search and autocomplete. It will allow filter maintainers to find the desired variable or function more quickly. [https://phabricator.wikimedia.org/T323698]
* The MJPEG and VP8 formats are removed from the video player. The MP4 format (MPEG-4 Part 2) is added instead, which provides higher quality videos to older iPhone devices.

:Hey @[[User:Dan Polansky|Dan Polansky]]! Thanks a ton, I didn't know that the Non-Commercial part of the license their work was licensed under led to that kind of copyright issue! Thanks for education and help :-). I haven't yet reached out, but I'm going to look for a format email that maybe someone else has already written on the wikipedia to help with this.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

=== Naked Eye Stars ===

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

* Approximately: ''{{mono|0297 0000 0000}}''
** [[w:MoM-z14|Oldest Observed Galaxy]]
&lt;/div&gt;

==== Second Set ====
* ''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'': Used to estimate cosmic look-back time ('''Figure 2'''), spanning from approximately 10.4 billion years ago to exactly 12:00:00 TAI on June 21, 1998. Key milestones from the presolar through geological eras include:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

== The Bully Mnemonic ==

&lt;math display=&quot;block&quot;&gt; {1 \, Sidereal \, Year} = {31,558,150 \, Seconds} &lt;/math&gt;

&lt;math display=&quot;block&quot;&gt; {1 \, Tropical \, Year} = {31,556,926 \, Seconds} &lt;/math&gt;

&lt;math display=&quot;block&quot;&gt; 1 \, Great \, Year \approx 25,824 \, Sidereal \, Years \approx 25,825 \, Tropical \, Years &lt;/math&gt;

&lt;math display=&quot;block&quot;&gt;{1 \, Galactic \, Year} \approx 8264 \, Great \, Year \approx 213,417,800 \, Tropical \, Years &lt;/math&gt;

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

* Approximately: ''{{mono|0297 0000 0000}}''
** [[w:MoM-z14|Oldest Observed Galaxy]]
&lt;/div&gt;

==== Second Set ====
* ''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'': Used to estimate cosmic look-back time ('''Figure 2'''), spanning from approximately 10.4 billion years ago to exactly 12:00:00 TAI on June 21, 1998. Key milestones from the presolar through geological eras include:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

[[File:Redshift-by-lookback-time-H0-comparison.png|frame|center|alt=A cosmic lookback plot showing Bully timestamps mapped to cosmic redshift.|Figure 5: A cosmic lookback plot showing Bully timestamps mapped to cosmic redshift.]]

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

== The Bully Mnemonic ==

&lt;math display=&quot;block&quot;&gt; {1 \, Sidereal \, Year} = {31,558,150 \, Seconds} &lt;/math&gt;

&lt;math display=&quot;block&quot;&gt; {1 \, Tropical \, Year} = {31,556,926 \, Seconds} &lt;/math&gt;

&lt;math display=&quot;block&quot;&gt; 1 \, Great \, Year \approx 25,824 \, Sidereal \, Years \approx 25,825 \, Tropical \, Years &lt;/math&gt;

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

&lt;/div&gt;

==== Second Set ====
* ''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'': Used to estimate cosmic look-back time ('''Figure 2'''), spanning from approximately 10.4 billion years ago to exactly 12:00:00 TAI on June 21, 1998. Key milestones from the presolar through geological eras include:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

[[File:Redshift-by-lookback-time-H0-comparison.png|frame|center|alt=A cosmic lookback plot showing Bully timestamps mapped to cosmic redshift.|Figure 5: A cosmic lookback plot showing Bully timestamps mapped to cosmic redshift.]]

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

* ''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'': Used to estimate cosmic look-back time ('''Figure 2'''), spanning from approximately 10.4 billion years ago to exactly 12:00:00 TAI on June 21, 1998. Key milestones from the presolar through geological eras include:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;

&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

* Approximately: ''{{mono|0297 0000 0000}}''
** [[w:MoM-z14|Oldest Observed Galaxy]]
&lt;/div&gt;

==== Second Set ====
* ''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'': Used to estimate cosmic look-back time ('''Figure 2'''), spanning from approximately 10.4 billion years ago to exactly 12:00:00 TAI on June 21, 1998. Key milestones from the presolar through geological eras include:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;

&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;

&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

== The Bully Mnemonic ==

&lt;math display=&quot;block&quot;&gt; {1 \, Sidereal \, Year} = {31,558,150 \, Seconds} &lt;/math&gt;

&lt;math display=&quot;block&quot;&gt; {1 \, Tropical \, Year} = {31,556,926 \, Seconds} &lt;/math&gt;

&lt;math display=&quot;block&quot;&gt; 1 \, Great \, Year \approx 25,824 \, Sidereal \, Years \approx 25,825 \, Tropical \, Years &lt;/math&gt;

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

** [[w:Cosmic_inflation|Cosmic Inflation]]
** [[w:Baryogenesis|Baryogenesis]]
** [[w:Big_Bang_nucleosynthesis|Nucleosynthesis]]
* Approximately: ''{{mono|0000 EA00 0000}}''
** [[w:Decoupling_(cosmology)|Decoupling]]

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;

&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

== The Bully Mnemonic ==

&lt;math display=&quot;block&quot;&gt; {1 \, Sidereal \, Year} = {31,558,150 \, Seconds} &lt;/math&gt;

&lt;math display=&quot;block&quot;&gt; {1 \, Tropical \, Year} = {31,556,926 \, Seconds} &lt;/math&gt;

&lt;math display=&quot;block&quot;&gt; 1 \, Great \, Year \approx 25,824 \, Sidereal \, Years \approx 25,825 \, Tropical \, Years &lt;/math&gt;

&lt;math display=&quot;block&quot;&gt;{1 \, Galactic \, Year} \approx 8264 \, Great \, Year \approx 213,417,800 \, Tropical \, Years &lt;/math&gt;


The '''Bully Mnemonic''' is a technique for remembering the exact number of seconds that occur in Earth's [https://en.wikipedia.org/wiki/Sidereal_year sidereal year] and [https://en.wikipedia.org/wiki/Tropical_year tropical year], a good approximation of the Earth's [https://en.wikipedia.org/wiki/Great_Year Great Year], and a rough approximation of the Solar System's [https://en.wikipedia.org/wiki/Galactic_year galactic year].

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

** [[w:Cosmic_inflation|Cosmic Inflation]]
** [[w:Baryogenesis|Baryogenesis]]
** [[w:Big_Bang_nucleosynthesis|Nucleosynthesis]]
* Approximately: ''{{mono|0000 EA00 0000}}''
** [[w:Decoupling_(cosmology)|Decoupling]]
** [[w:Recombination_(cosmology)|Recombination]]
* Approximately: ''{{mono|0100 0000 0000}}''
** [[w:Star_formation|First Star Formation]]
* Approximately: ''{{mono|0297 0000 0000}}''
** [[w:MoM-z14|Oldest Observed Galaxy]]
&lt;/div&gt;

==== Second Set ====
* ''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'': Used to estimate cosmic look-back time ('''Figure 2'''), spanning from approximately 10.4 billion years ago to exactly 12:00:00 TAI on June 21, 1998. Key milestones from the presolar through geological eras include:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;
* Approximately: ''{{mono|3B00 0000 0000}}''
** [[w:Murchison_meteorite|Oldest Presolar Grains]]
* Approximately: ''{{mono|5720 9000 0000}}''
** [[w:Hadean|Hadean Eon Begins]]
* Approximately: ''{{mono|5C2A 0000 0000}}''
** [[w:Archean|Archean Eon Begins]]

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;

&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;

&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

&lt;math display=&quot;block&quot;&gt; {1 \, Sidereal \, Year} = {31,558,150 \, Seconds} &lt;/math&gt;

&lt;math display=&quot;block&quot;&gt; {1 \, Tropical \, Year} = {31,556,926 \, Seconds} &lt;/math&gt;

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;

&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

&lt;math display=&quot;block&quot;&gt; {1 \, Sidereal \, Year} = {31,558,150 \, Seconds} &lt;/math&gt;

&lt;math display=&quot;block&quot;&gt; {1 \, Tropical \, Year} = {31,556,926 \, Seconds} &lt;/math&gt;

&lt;math display=&quot;block&quot;&gt; 1 \, Great \, Year \approx 25,824 \, Sidereal \, Years \approx 25,825 \, Tropical \, Years &lt;/math&gt;

&lt;math display=&quot;block&quot;&gt;{1 \, Galactic \, Year} \approx 8264 \, Great \, Year \approx 213,417,800 \, Tropical \, Years &lt;/math&gt;


The '''Bully Mnemonic''' is a technique for remembering the exact number of seconds that occur in Earth's [https://en.wikipedia.org/wiki/Sidereal_year sidereal year] and [https://en.wikipedia.org/wiki/Tropical_year tropical year], a good approximation of the Earth's [https://en.wikipedia.org/wiki/Great_Year Great Year], and a rough approximation of the Solar System's [https://en.wikipedia.org/wiki/Galactic_year galactic year].

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;

&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

&lt;/div&gt;

==== Second Set ====
* ''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'': Used to estimate cosmic look-back time ('''Figure 2'''), spanning from approximately 10.4 billion years ago to exactly 12:00:00 TAI on June 21, 1998. Key milestones from the presolar through geological eras include:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;

&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

&lt;/div&gt;

==== Second Set ====
* ''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'': Used to estimate cosmic look-back time ('''Figure 2'''), spanning from approximately 10.4 billion years ago to exactly 12:00:00 TAI on June 21, 1998. Key milestones from the presolar through geological eras include:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

&lt;/div&gt;

==== Second Set ====
* ''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'': Used to estimate cosmic look-back time ('''Figure 2'''), spanning from approximately 10.4 billion years ago to exactly 12:00:00 TAI on June 21, 1998. Key milestones from the presolar through geological eras include:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

&lt;/div&gt;

==== Second Set ====
* ''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'': Used to estimate cosmic look-back time ('''Figure 2'''), spanning from approximately 10.4 billion years ago to exactly 12:00:00 TAI on June 21, 1998. Key milestones from the presolar through geological eras include:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

&lt;/div&gt;

==== Second Set ====
* ''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'': Used to estimate cosmic look-back time ('''Figure 2'''), spanning from approximately 10.4 billion years ago to exactly 12:00:00 TAI on June 21, 1998. Key milestones from the presolar through geological eras include:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

&lt;/div&gt;

==== Second Set ====
* ''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'': Used to estimate cosmic look-back time ('''Figure 2'''), spanning from approximately 10.4 billion years ago to exactly 12:00:00 TAI on June 21, 1998. Key milestones from the presolar through geological eras include:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

* ''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'': Used to estimate cosmic look-back time ('''Figure 2'''), spanning from approximately 10.4 billion years ago to exactly 12:00:00 TAI on June 21, 1998. Key milestones from the presolar through geological eras include:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

&lt;/div&gt;

==== Second Set ====
* ''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'': Used to estimate cosmic look-back time ('''Figure 2'''), spanning from approximately 10.4 billion years ago to exactly 12:00:00 TAI on June 21, 1998. Key milestones from the presolar through geological eras include:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

&lt;/div&gt;

==== Second Set ====
* ''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'': Used to estimate cosmic look-back time ('''Figure 2'''), spanning from approximately 10.4 billion years ago to exactly 12:00:00 TAI on June 21, 1998. Key milestones from the presolar through geological eras include:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

* ''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'': Used to estimate cosmic look-back time ('''Figure 2'''), spanning from approximately 10.4 billion years ago to exactly 12:00:00 TAI on June 21, 1998. Key milestones from the presolar through geological eras include:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

* ''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'': Used to estimate cosmic look-back time ('''Figure 2'''), spanning from approximately 10.4 billion years ago to exactly 12:00:00 TAI on June 21, 1998. Key milestones from the presolar through geological eras include:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

* ''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'': Used to estimate cosmic look-back time ('''Figure 2'''), spanning from approximately 10.4 billion years ago to exactly 12:00:00 TAI on June 21, 1998. Key milestones from the presolar through geological eras include:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

&lt;/div&gt;

==== Second Set ====
* ''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'': Used to estimate cosmic look-back time ('''Figure 2'''), spanning from approximately 10.4 billion years ago to exactly 12:00:00 TAI on June 21, 1998. Key milestones from the presolar through geological eras include:
&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

&lt;math display=&quot;block&quot;&gt; {1 \, Sidereal \, Year} = {31,558,150 \, Seconds} &lt;/math&gt;

&lt;math display=&quot;block&quot;&gt; {1 \, Tropical \, Year} = {31,556,926 \, Seconds} &lt;/math&gt;

&lt;math display=&quot;block&quot;&gt; 1 \, Great \, Year \approx 25,824 \, Sidereal \, Years \approx 25,825 \, Tropical \, Years &lt;/math&gt;

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

[[File:Redshift-by-universe-age-H0-comparison.png|frame|center|alt=Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.|Figure 4: Age of the Universe plot showing Bully timestamps mapped to cosmic redshift.]]

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

[[Bully_Metric_Timestamp_units|Learn More About Contextualized vs Decontextualized time]]

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

&lt;math display=&quot;block&quot;&gt; {1 \, Sidereal \, Year} = {31,558,150 \, Seconds} &lt;/math&gt;

&lt;math display=&quot;block&quot;&gt; {1 \, Tropical \, Year} = {31,556,926 \, Seconds} &lt;/math&gt;

&lt;math display=&quot;block&quot;&gt; 1 \, Great \, Year \approx 25,824 \, Sidereal \, Years \approx 25,825 \, Tropical \, Years &lt;/math&gt;

&lt;math display=&quot;block&quot;&gt;{1 \, Galactic \, Year} \approx 8264 \, Great \, Year \approx 213,417,800 \, Tropical \, Years &lt;/math&gt;


The '''Bully Mnemonic''' is a technique for remembering the exact number of seconds that occur in Earth's [https://en.wikipedia.org/wiki/Sidereal_year sidereal year] and [https://en.wikipedia.org/wiki/Tropical_year tropical year], a good approximation of the Earth's [https://en.wikipedia.org/wiki/Great_Year Great Year], and a rough approximation of the Solar System's [https://en.wikipedia.org/wiki/Galactic_year galactic year].

The '''Bully Metric Timestamp''' system is an alternative timekeeping framework that utilizes the orbit of the Sun around the Milky Way Galaxy to mark the passage of time. A new successive Bully timestamp is realized each time the Sun advances by approximately one solar radius along its path through the Galaxy. Using '''12-digit''' [[w:hexadecimal|hexadecimal]] timestamps, the Bully system has enough unique identifiers to span the entire history of the universe—from the Big Bang into the far-distant future. The total capacity of the system is:
&amp;thinsp;
:&lt;math&gt;16^{12} \times 3,055 \text{ sec} \approx 27.25 \text{ billion years}&lt;/math&gt;
&amp;thinsp;
[[File:Bully_Metric_Galactic_Orbit_1_Timestamp.png|thumb|right|450px|alt=Diagram showing the Sun advancing a distance equal to its own radius along its galactic trajectory over a period of 3055 seconds.|'''Figure 1:''' Motion of the Sun between two successive Bully timestamps.]]

The Sun orbits the center of the Milky Way galaxy at a very fast speed, roughly 227.7 kilometers per second (km/s), which equals approximately 0.076% of the speed of light. Even though the Sun is moving very quickly, it is also physically immense. The radius of the Sun (&lt;math&gt;R_\odot&lt;/math&gt;) is 695,700 kilometers. Dividing the solar radius by the galactic orbital velocity, we find that it takes approximately '''3055 seconds''' for the Sun to travel a distance equal to its own radius:
&amp;thinsp;
:&lt;math&gt;\Delta t = \frac{695,700 \text{ km}}{227.7 \text{ km/s}} \approx 3055 \text{ seconds}&lt;/math&gt;
&amp;thinsp;
'''Figure 1''' illustrates the physical movement of the Sun between two successive Bully timestamps. Timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. The sequential timestamp, '''8209 2800 0001''', occurred 3,055 seconds later at '''12:50:55 TAI on June 21, 1998''' (where TAI is International Atomic Time). As visually shown in Figure 1, the Sun orbited a distance of one solar radius during this 3,055 second time period.

=== The Heliosphere ===
The heliosphere, it turns out, is not actually a sphere. As shown in '''Figure 2''', the heliosphere is a vast, oblong, tailed, bubble-like region that extends from the Sun into the surrounding space. The heliosphere is somewhat analogous to Earth's atmosphere, except that Earth's atmosphere is a comparatively thin layer of gas that remains near the Earth's surface. By comparison, the heliosphere is a plasma that is constantly blasted out into space due to the extreme heat and energy of the Sun.

[[File:Bully_Metric_Galactic_Orbit_65536_Timestamps.png|thumb|right|450px|alt=Diagram showing the Sun traveling through the oblong shape of the heliosphere over a span of 16 to the 4th power timestamps.|'''Figure 2:''' Motion of the Sun during the passage of 16&lt;sup&gt;4&lt;/sup&gt; Bully timestamps.]]

The heliosphere is very large. It is so vast that if it were truly spherical, its diameter would be on an order of magnitude similar to '''16&lt;sup&gt;4&lt;/sup&gt; (65,536) solar radii'''. The digit in the '''fifth position''' in a Bully timestamp represents the time required for the Sun to orbit for '''6.344 years''', which covers a distance of approximately '''65,536 solar radii''', or roughly the diameter of one spherical heliosphere. Figure 2 illustrates the orbit of the Sun (Sun not drawn to scale) over a period of 6.344 years. 

As explained previously, timestamp '''8209 2800 0000''' is defined to have occurred at exactly '''12:00:00 TAI on June 21, 1998'''. Timestamp '''8209 2801 0000''' therefore occurred roughly 6.344 years later at '''18:34:40 TAI on October 24, 2004'''.

Incidentally, the Voyager 1 spacecraft crossed into the heliosheath, as shown in Figure 2, on December 16th 2004. Both Voyager spacecraft (Voyager 1 and Voyager 2) have since crossed entirely out of the heliosphere and entered the surrounding interstellar space.

== The Galactic Calendar ==
[[File:Sun_in_orbit_around_Galactic_Centre.gif|thumb|right|300px|alt=Diagram showing multiple stars moving along their respective orbital paths around the galactic center over a span of 250 million years.|'''Figure 3:''' Stars orbiting around the Galactic center during a 250 million-year time period.]]
A '''galactic year''', also known as a '''cosmic year''', is the duration of time required for the Sun (or any other star) to orbit once around the center of the Milky Way Galaxy. The duration of the galactic year is not a fixed constant, but rather, it depends on the path that a particular star follows as it orbits (see Figure 3). Stars closer to the center will orbit much more quickly than those on the outer edges. The stars shown in '''Figure 3''' all eventually localized near the Sun despite having vastly different historical orbital trajectories, visually illustrating the long-term uncertainty of galactic orbits.

=== Bully Galactic Years ===
If the Sun followed a perfectly circular orbit around the Milky Way, as estimated in the text in the lower right corner of '''Figure 4''', the radius of that orbit would be approximately 26,000 light-years. The time required for the Sun to complete one full circular orbit would be calculated by dividing the orbital circumference by the orbital speed:
&amp;thinsp;
:&lt;math&gt;\begin{aligned}
\Delta t &amp;= \frac{2\pi \times 26,000 \text{ light-years}}{230 \text{ km/s}} \\
&amp;\approx 213 \text{ million years}
\end{aligned}&lt;/math&gt;
&amp;thinsp;
[[File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg|thumb|center|600px|alt=Diagram showing the intertwined orbital paths of the Earth and Moon as they accompany the Sun on its massive orbit around the Milky Way center.|'''Figure 4:''' Motion of the Sun, Earth, and Moon around the Milky Way Galaxy.]]
&amp;thinsp;
Within the context of the Bully timekeeping system, a '''Bully galactic year''' is defined to have a duration of exactly '''2&lt;sup&gt;41&lt;/sup&gt; Bully timestamps''' (approximately 213 million years). While this is not identical to a true, observed galactic year, it should be noted that the true long-term trajectory of the Sun is inherently chaotic and unpredictable over deep time. Therefore, this fixed power-of-two value serves as a reasonable approximation.

=== Bully Galactic Year 65 ===
Since the Bully system utilizes hexadecimal notation and a Bully Galactic Year spans 2&lt;sup&gt;41&lt;/sup&gt; Bully timestamp intervals, the positional values of the highest digits map directly to large cosmic eras:

* The '''twelfth digit''' (the far-left position) scales in increments of 8 Bully Galactic Years:
**&lt;math&gt;\frac{16^{11}}{2^{41}} = 8&lt;/math&gt;.
* The '''eleventh digit''' scales in increments of half a Bully Galactic Year:
**&lt;math&gt;\frac{16^{10}}{2^{41}} = \frac{1}{2}&lt;/math&gt;.
* The '''tenth digit''' scales in increments of one-thirty-second of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{9}}{2^{41}} = \frac{1}{32}&lt;/math&gt;.
* The '''ninth digit''' scales in increments of one five-hundred-and-twelfth of a Bully Galactic Year:
**&lt;math&gt;\frac{16^{8}}{2^{41}} = \frac{1}{512}&lt;/math&gt;.

Any timestamp in the range '''8200 0000 0000''' through '''83FF FFFF FFFF''' indicates that the system is recording time within the '''65th Bully Galactic Year''' of the Universe.  However, the Sun (and our solar system) did not come into existence until approximately 44 Bully Galactic Years after the Big Bang, meaning our solar system is only '''21 Bully Galactic Years old'''.

=== Galactic Weeks ===
A '''Galactic Week''' can be thought of as the approximate duration of time required for the Sun to orbit '''6.9 degrees''' around the galactic center (approximately 4.1 million years), so that 52 Galactic Weeks is equivalent to one Galactic Year. The following table (see Figure 5) illustrates the division of one Galactic Year's worth of Bully timestamps into 52 equal portions. Galactic Year &quot;65&quot; begins with Bully timestamp '''8200 0000 0000''' and ends with timestamp '''83FF FFFF FFFF'''. We are currently nearing the end of the '''1st Quarter, Galactic Week 0 (8200 0000 0000 - 8209 D89D 89D7)'''.

==== The Metonic Cycle ====
The '''Metonic cycle''' is a period of approximately 19 solar years, after which the moon's phases recur on the same days of the year. For example, a New Moon occurred on July 23 in 1998, and nineteen years later, in 2017, a New Moon again occurred on July 23. The last four hex digits of the Bully timestamp cycle approximately three times per Metonic cycle as illustrated in the following list:

== Bully Timestamp Realization ==
Each Bully timestamp is '''realized''' exactly 3055 seconds TAI after the previous one.  However, since atomic clocks did not exist prior to the 1950's, any assignment of Bully timestamps prior to 1958 should be viewed as an '''estimate''' of how time might have transpired in the past, rather than an actual realization of Bully time. Similarly, any assignment of future timestamps should be viewed as an estimate of what may occur, rather than a realization. Bully timestamps should only be considered &quot;realized&quot; when time is measured with an accuracy of &lt;math&gt;{10}^{-10}&lt;/math&gt;. There have been over 700,000 realized Bully timestamps during the era of modern atomic time keeping (1958 AD ... present).

=== Time Estimation Divisions ===
[[File:History-of-the-Universe With Bully Timestamps.jpg|frame|center|text-bottom|Figure 1: History of the Universe with a few example Bully timestamps shown in red.]]
For the purpose of time estimation, the Bully system's time range is divided into three distinct sets:

==== First Set ====
* ''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'': Used to estimate time during the universe's formative period ('''Figure 1'''), spanning roughly 3 billion years beginning with the Big Bang. The following list highlights key events from selected timestamps during this formative era:

&lt;div style=&quot;background-color: #f0f4f7; padding: 15px; border-left: 5px solid #009688;&quot;&gt;

=== Time Estimation Using Cosmic Redshift ===
In [[w:physics|physics]], a '''redshift''' is an increase in [[w:wavelength|wavelength]] (or a decrease in [[w:frequency|frequency]]) of [[w:electromagnetic radiation|electromagnetic radiation]]. Cosmological redshifts are driven directly by the [[w:expansion of the universe|expansion of the universe]]. The redshift value is denoted by {{math|''z''}}, where the ratio of observed to emitted wavelength is {{math|1 + ''z''}}.

If the original wavelength of a radiation source is known, its cosmological redshift can reveal the light travel time. However, mapping redshift precisely to elapsed time requires an exact cosmological model. Ongoing measurement tension surrounding the [[w:Hubble constant|Hubble constant]] introduces uncertainty into calculations of the exact [[w:Age of the universe|age of the universe]] and distant stars.

This cosmological uncertainty directly affects the accuracy of assigning Bully timestamps. The table in Figure 3 contrasts two estimation tracks based on competing cosmological datasets. One column applies the local distance ladder framework from the '''SH0ES Team''' (corresponding to a younger universe estimate of 12.7 Gyr). The other utilizes cosmic microwave background data from the '''Planck Collaboration''' (yielding an older universe estimate of approximately 13.8 Gyr). Larger z values correspond with the more distant past.

The forward-progressing timestamps ''{{mono|0000 0000 0000}}'' through ''{{mono|1FFF FFFF FFFF}}'' are illustrated in Figure 4 (bottom of figure). By convention, these timestamps are assumed to begin at the Big Bang and progress forward for approximately three billion years.

Timestamps ''{{mono|2000 0000 0000}}'' through ''{{mono|8200 0000 0000}}'' (top of Figure 4) measure &quot;lookback&quot; time anchored at timestamp ''8209 2800 0000''. Because the total age of the universe is unfixed, the precise mathematical relationship between universal age and lookback time remains indefinite. Two different possible universe ages are shown with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The data illustrated in Figure 5 is the same as is shown in Figure 4, but Figure 5 plots against lookback time on the x-axis, so in this plot the universe age is unfixed with the Planck Collaboration shown in red and the SH0ES Team shown in blue.

The table in Figure 6 is similar to the table in Figure 3, in that it contrasts two estimation tracks based on competing cosmological datasets. However, whereas the data in Figure 3 was for large z values, Figure 6 shows small z values. Smaller z values correspond with the recent past.

===  Time Estimation Relativistic and Cosmological Considerations ===
What does it mean when cosmologists state that the universe is approximately 13.8 billion years old? According to Einstein's theories of special and general relativity, time passes differently for each observer depending on their path through spacetime and the gravitational forces in their vicinity. How, then, can the universe have a single age? Shouldn't its age depend entirely on the observer's frame of reference?

The &quot;age of the universe&quot; cited by cosmologists is actually its maximum possible age. Among all paths an observer could take through spacetime, one specific trajectory maximizes elapsed time. This privileged frame of reference belongs to an observer who remains at rest relative to the Cosmic Microwave Background (CMB) and resides in a region of space with negligible matter. We will refer to this as the &quot;CMB rest frame.&quot;

Importantly, Bully timestamps are divided into three distinct sets, with only the first set (''{{mono|0000 0000 0000}}'' — ''{{mono|1FFF FFFF FFFF}}'') utilizing the CMB rest frame. Timestamps in the third set (''{{mono|8209 2800 0000}}'' — ''{{mono|FFFF FFFF FFFF}}'') are realized using atomic clocks at sea level on Earth. Due to relativistic time dilation, these terrestrial clocks run slower than identically constructed clocks placed at rest in empty space. All &quot;realized&quot; Bully timestamps from 1958 to the present conform to Earth's sea-level frame of reference.

Furthermore, the &quot;estimated&quot; Bully timestamps in the second set (''{{mono|2000 0000 0000}}'' — ''{{mono|8209 2800 0000}}'') are typically derived from the radioactive decay of samples found on or within the Earth; thus, these samples decay at a rate comparable to Earth's sea-level frame. The oldest timestamps in this second set come from presolar grains, which formed in different star systems prior to the emergence of our solar system. Because some of these samples may have traveled through space in frames of reference drastically different from Earth's current sea-level frame, the accuracy of these cosmic estimates is inherently limited.

== Contextualized vs. Decontextualized Time ==

Local clocks and calendars reflect '''contextualized time''', which uses region-specific offsets from Coordinated Universal Time (UTC) to align with physical reality. This time is &quot;contextual&quot; because it provides an intuitive sense of conditions at some specific geographic location; for instance, a traveler arriving in London at 4:00 a.m. can instinctively expect darkness and quiet streets. To maintain this alignment with Earth's natural cycles, UTC requires periodic &quot;leaps&quot; (seconds and years). In '''Figure 10''', the light blue line represents Earth's irregular rotation ('''UT1'''), while the dark blue line shows '''UTC''', which is manually adjusted with leap seconds to track UT1.

In contrast, standards such as International Atomic Time ('''TAI'''), Terrestrial Time ('''TT'''), and '''GPS time''' are '''decontextualized'''. They are independent of Earth's rotation, meaning they do not correspond to &quot;true time&quot; at any specific geographical location. Represented by the black lines in '''Figure 10''', these standards track a continuous, uniform interval measured by atomic clocks. This uninterrupted linearity is vital for scientific and technical systems, where the discontinuities introduced by leap seconds could lead to critical errors or system failures.

[[File:Bully Timestamps in relation to modern time keeping.png|frame|center|text-bottom|Figure 10: Modern Time Keeping]]

The various decontextualized standards currently in use are effectively &quot;frozen&quot; in the astronomical conditions present at the time of their deployment. Because long-term changes in Earth's motion are unpredictable, each system launched with a different initial offset. For example, when GPS was launched in 1980, the '''Delta T''' adjustment (TT-UTC) exceeded 51 seconds. In contrast, the 1972 LORAN-C upgrade began with an adjustment closer to 42 seconds. This historical discrepancy results in a permanent nine-second offset between GPS and LORAN-C. Similarly, LORAN-C remains offset from TAI (deployed in 1958) by exactly ten seconds.

The Bully timestamp system, shown on the far-right axis of '''Figure 10''', follows the same uniform, decontextualized logic as TAI and TT but avoids this &quot;legacy offset&quot; confusion. Unlike existing standards, Bully timestamps are not linked to others by a constant, arbitrary time offset. This independence ensures they are uniquely recognizable and impossible to misinterpret.

== Why do we need Bully timestamps? ==

All the timestamps in '''Figure 11''' refer to one single, simultaneous moment in time. The left frame illustrates the fragmentation of Coordinated Universal Time (UTC) through time zones. For instance, on June 21, 1998, a UTC time of 11:59:29 a.m. in Accra, Ghana, was simultaneously 8:59:29 p.m. in Tokyo. These time zone offsets are not based on science, but on '''political mandates''' that have resulted in [https://en.wikipedia.org/wiki/List_of_UTC_offsets 38 distinct UTC offsets], including confusing half- and quarter-hour increments.

==== Legacy Decontextualized Timestamps ====

The decontextualized timestamps (TAI, TT, GPS) in the upper-right frame of '''Figure 11''' attempt to solve the UTC geographic fragmentation problem, yet they remain &quot;cluttered&quot; by Gregorian formatting. Applying a Gregorian date—which is built to track the Sun—to an atomic standard is a '''category error'''. Seeing three different timestamps share the same date while differing by several &quot;leap&quot; seconds is intellectually disorienting because the date has been stripped of its astronomical meaning. In these technical contexts, the Gregorian format is an artificial mask applied for convenience, hiding the true linear nature of time.

For scientific and technical applications, TAI and TT are often expressed via '''Modified Julian Date (MJD)'''—a continuous count of SI days since a fixed epoch. While MJD avoids Gregorian irregularities, it remains &quot;tethered&quot; to the 86,400-second day, a unit that is astronomically meaningless when decontextualized. Similarly, '''GPS time''' relies on a week-based count (since January 6, 1980), forcing a technical system to conform to an arbitrary seven-day cycle. Both systems are cumbersome &quot;hybrids&quot; that attempt to measure linear time using units designed for Earth’s rotation.

==== Decontextualized Bully Timestamps ====

The '''Bully Timestamp''', shown in the lower-right frame of '''Figure 11''', breaks the Gregorian formatting tether. It is a single, unique identifier that applies simultaneously to all locations on Earth because it is never adjusted for geography or orbital drift. For example, Bully timestamp {{mono|8209 2800 0000}} was realized at the exact moment the UTC based clock read 11:59:29 a.m. in Accra and 8:59:29 p.m. in Tokyo. By discarding the baggage of weeks, days, and hours, the Bully timestamp emerges as the least ambiguous format for representing universal, decontextualized time.

== The Foundations of Bully Metric ==

The Bully Timestamp System was derived from the orbital periods of major Solar System bodies. Specifically, the duration of Earth's '''sidereal year''' (~31,558,150 seconds) is roughly equal to &lt;math&gt;10,330 \times 3,055&lt;/math&gt; SI seconds. This foundational constant—3,055 seconds—serves as the building block for the Bully timestamp system.

The name &quot;Bully&quot; is a dual-reference to the massive astronomical objects that define our local spacetime. In an archaic sense, &quot;bully&quot; means '''&quot;beautiful&quot; or &quot;excellent,&quot;''' describing the celestial harmony of the cosmos. In the modern sense, it refers to the '''dominance and gravitational influence''' of &quot;bullies&quot; like [https://en.wikipedia.org/wiki/Sagittarius_A* Sagittarius A*], the [https://en.wikipedia.org/wiki/Sun Sun], and giant planets like Jupiter and Saturn. These massive bodies dictate the motion of everything around them, serving as the physical anchors for the Bully Metric system.

== The Bully Mnemonic ==

&lt;math display=&quot;block&quot;&gt; {1 \, Sidereal \, Year} = {31,558,150 \, Seconds} &lt;/math&gt;

&lt;math display=&quot;block&quot;&gt; {1 \, Tropical \, Year} = {31,556,926 \, Seconds} &lt;/math&gt;

&lt;math display=&quot;block&quot;&gt; 1 \, Great \, Year \approx 25,824 \, Sidereal \, Years \approx 25,825 \, Tropical \, Years &lt;/math&gt;

&lt;math display=&quot;block&quot;&gt;{1 \, Galactic \, Year} \approx 8264 \, Great \, Year \approx 213,417,800 \, Tropical \, Years &lt;/math&gt;


The '''Bully Mnemonic''' is a technique for remembering the exact number of seconds that occur in Earth's [https://en.wikipedia.org/wiki/Sidereal_year sidereal year] and [https://en.wikipedia.org/wiki/Tropical_year tropical year], a good approximation of the Earth's [https://en.wikipedia.org/wiki/Great_Year Great Year], and a rough approximation of the Solar System's [https://en.wikipedia.org/wiki/Galactic_year galactic year].

:''Humanity is one misunderstanding, one miscalculation away from nuclear annihilation. ... This is madness. We must reverse course.''
:  -- [[w:António Guterres|UN Secretary General António Guterres]]  (2022)&lt;ref&gt;Jacobsen (2024), BBC (2022).&lt;/ref&gt;

:This book is a combination instruction manual on [[w:Media literacy|media literacy]] and an invitation to you to support collaborative / crowd-sourced research on how to improve the world's understanding of media literacy and how to accelerate its understanding and use globally for the betterment of humanity. 

Part I of this book on ''[[Media Literacy and You]]'' discusses &quot;The media and political economy&quot;. Except in times of terror, massive lawlessness or war, most humans place a high priority on their financial situation, the primary focus of Part I. Part II on &quot;The media and war&quot; focuses on security concerns starting with this chapter on &quot;Deterrence without threat&quot;. 

== Introduction ==

Every individual and group has a right and an obligation to defend itself. Unfortunately, when most humans&lt;ref&gt;We distinguish here between &quot;humans&quot; and &quot;people&quot; or &quot;persons&quot;, because under current US law, corporations are &quot;people&quot; and money is speech, per the US Supreme Court decision in ''[[w:Citizens United v. FEC|Citizens United v. FEC]]'' (2010) and many other judicial rulings and US law such as the [[w:Patriot Act|Patriot Act]] of 2001.&lt;/ref&gt; think of defense, they often think of violent responses to provocations. 

However, there is a growing body of research documenting 

:(a) how most uses of violence are counterproductive, and 
:(b) there are usually nonviolent options to violence that would more effectively promote broadly shared peace and prosperity for the long term. 

This research is rarely discussed by major media outlets, because it would offend the &quot;people&quot;&lt;ref&gt;We put &quot;people&quot; in quotes in this essay, because that term includes corporations under current US law.&lt;/ref&gt; who control most of the money for the media: Nonviolence threatens their ability to get compliance from security forces. As a result, many elites prefer to use force to the detriment of the bottom 99 percent of humanity. As discussed below, a military posture that supports projecting force beyond one’s own borders may be as likely to ''provoke'' as ''prevent'' an attack.&lt;ref&gt;For example, Lebow (2025) cites some of his previous work with others to support the claim that large militaries have been &quot;more provocative than preventative in&quot; their effects. And Lebow (2024) insists that, &quot;Policymakers respond more instinctively than analytically in deciding that some policy is or is not in the national interest.&quot; See also Lebow et al. (2023).&lt;/ref&gt; 

This chapter outlines a 3-part strategy that research suggests would more likely lead to better outcomes for the vast majority of humans: 

# Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content. 
# Training in nonviolent noncooperation for anyone willing to listen. 
# Forbid uses of force beyond one’s own borders and covert interference in foreign countries. 

We now discuss each of these briefly. 

== 1. Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content. == 

It seems that

:''Primary drivers of every major conflict include differences between the media that the different parties find crecible.''

In a recent interview with [[w:Fordham University|Fordham University]] Professor Emerita of Communications Robin Andersen,&lt;ref name=Andersen&gt;&lt;!--Robin Andersen--&gt;{{cite Q|Q132982358}}&lt;/ref&gt; she agreed with this claim and added: 

:''We only have enemies of our very own making.''

The media are involved in this, because:  

:''The major media create the stage upon which politicians read their lines.''&lt;ref&gt;In 1791 James Madison, who represented part of Virginia in the US House of Representatives 1789-1801 and later became the 4th President of the US (1809-1819), said, &quot;Public opinion sets bounds to every government, and is the real sovereign in every free one.&quot; Quoted from the ''[[w:National Gazette|National Gazette]]'' (published 1791-1793) by Schmeller (2009, p. 36) and Sauer (2016, p. 5). Sauer described how the American Revolutionaries, especially the first four US presidents, planted stories in newspapers to build support for how they dealt with the [[w:Barbary corsairs|Barbary pirates]], who were seizing merchant ships, raiding European coastal towns and villages, and selling European captives into slavery. The first two US presidents, [[w:George Washington|Washington]] and [[w:John Adams|Adams]], used that support for protecting US shipping and citizens by paying tribute to government leaders in Morocco, Algeria, Tunisia, and Libya. The next two presidents, [[w:Thomas Jefferson|Jefferson]] and [[w:James Madison|Madison]], convinced Congress to fund a navy and marines to fight the [[w:Barbary Wars|Barbary Wars]]. This included the [[w:Battle of Derna (1805)|Battle of Derna]]  (April-May 1805), memorialized in the [[w:Marines' Hymn|Marines' Hymn]], which mentions actions &quot;to the shores of Tripoli&quot;. Sauer described how the policies were sold to the public via planted stories in the different partisan newspapers.&lt;/ref&gt; 

This works because (a) virtually everyone thinks they know more than they do ([[w:Overconfidence effect|overconfidence effect]]), and (b) virtually everyone prefers information and sources consistent with preconceptions ([[w:confirmation bias|confirmation bias]]). 

Also, in many, perhaps all, countries, the primary constituency for foreign and military policy is the people with foreign business interests. Many of these people also control substantial portions of the money for the media, which have too often encourage questionable and counterproductive uses of military force.&lt;ref&gt;If we [[w:follow the money|follow the money]], we might find that &quot;watchdogs generally protect the people who feed them&quot;, as discussed in the 2025-09-25 interview with British journalist and media reform activist Dan Hind discussing how the British [[Media Reform Coalition challenges anti-democratic media bias in the UK]].&lt;/ref&gt; 

=== Examples === 

A leader in documenting the role of the media in armed conflict is Robin Andersen,&lt;ref&gt;e.g., Andersen (2006, 2026).&lt;/ref&gt; but she is not alone. For example, [[w:University of Denver|University of Denver]] journalism professor Kareem El Damanhoury&lt;ref name=Daman&gt;&lt;!--Kareem El Damanhoury--&gt;{{cite Q|Q113752441}}&lt;/ref&gt; has compared how [[w:Gaza Strip|Gaza]] has been framed differently by [[w:Al Jazeera Media Network|Al Jazeera]], the [[w:BBC|BBC]]&lt;ref&gt;El Damanhoury et al. (2025).&lt;/ref&gt; and [[w:Fox News|Fox]].&lt;ref&gt;El Damanhoury and Saleh (2024).&lt;/ref&gt;&lt;ref&gt;Some of El Damanhoury's work in this regard [[Differences between media outlets including coverage of Gaza|is reviewed in a 2025-11-20 interview with him]].&lt;/ref&gt; 

==== World War I ====

Andersen's (2006) ''A Century of Media, A Century of War'' begins with a discussion of &quot;The birth of war propaganda&quot; in &quot;The Great War and the Fight between Good and Evil&quot;.&lt;ref&gt;Andersen (2006, ch. 1)&lt;/ref&gt; 

A more detailed but compatible discussion of the media and [[w:World War I|World War I]] is given by [[w:John Maxwell Hamilton|John Maxwell Hamilton]]. Among other things, he said: {{quote|

The first iron law of propaganda is that only the enemy does it.&lt;ref&gt;Hamilton (2020, p. 642). See also the [[John Maxwell Hamilton on American propaganda|2025-12-11 interview with Hamilton]].&lt;/ref&gt;}} 

[[File:MB Walker - German bayoneting children - Life - July 25, 1915.png|thumb|left|Figure 1. Stories of German soldiers impaling children on their bayonets were widely reported during the war. However, no credible evidence was found to support these claims when questions were raised after the war.&lt;ref&gt;{{cite web|title=Alleged German atrocities: Bryce report|url=http://www.nationalarchives.gov.uk/pathways/firstworldwar/spotlights/p_alleged_german.htm|publisher=The National Archives|access-date=13 July 2014}}&lt;/ref&gt;]]

Andersen (2006, pp. 8-9) said, {{quote|

James Bryce, the former British ambassador to the United States, ... helped prepare a sixty-one page ''Report on the Committee on alleged German Outrages'', which was translated into thirty languages and was said to be based on twelve hundred depositions ... included gruesome and titillating details of how German soldiers publicly raped Belgian girls in the marketplace at Liege and bayonetted a two-year-old child. ... [A]fter the war a Belgian commission of inquiry found no evidence for any major accusation in the report. ...}}
{{quote|
German propagandists, on the other hand, ... &quot;bungled, because they were naïve: they thought the success of the war depended almost solely on military strategy and therefore they tended to neglect propaganda.&quot; ... Thus, when German soldiers shot some Allied nurses who had carried weapons, they admitted it openly. The Allies reported the incident as an atrocity and featured it in press propaganda. When French troops shot German nurses under similar circumstances, the Germans failed to exploit it.}} 

==== Jonathan Swift 1710 ====

This is not limited to World War I. In 1710, [[w:Jonathan Swift|Jonathan Swift]] reportedly said, &quot;Falsehood flies, and truth comes limping after ... like a physician, who hath found out an infallible medicine, after the patient is dead.&quot;&lt;ref name=Swift&gt;Excerpted from a line in [[Wikiquote:Jonathan Swift]] consulted 2026-04-13.&lt;/ref&gt;  

==== The Marines' Hymn ====

The [[w:Marines' Hymn|Marine Corps Hymn]] begins, {{quote|

From the Halls of Montezuma

To the shores of Tripoli;

We fight our country's battles

In the air, on land, and sea.}}

The &quot;[[w:Battle of Chapultepec|Halls of Montezuma]]&quot; refer to the [[w:Mexican–American War|Mexican–American War]], which was fought to expand slavery first into [[w:Texas|Texas]]  -- and supporters of slavery hoped that would help expand slavery further west. The &quot;[[w:Battle of Derna (1805)|shores of Tripoli]]&quot; were part of the [[w:Barbary Wars|Barbary Wars]], which were fought to reduce the need to pay (a) tribute to the [[w:Barbary Coast|Barbary or Berber]] states of [[w:Morocco|Morocco]], [[w:Algeria|Algeria]], [[w:Tunisia|Tunisia]], and [[w:Libya|Libya]] or (b) ransom to [[w:Barbary corsairs|Barbary pirates]], who were otherwise capturing Christians and selling them into slavery. 

Did the bottom 99 percent of the US population of that time benefit? Or did these wars (and any tribute and ransom paid by the US government before the Barbary wars) constitute a hidden transfer of wealth from the poor to the wealthy? 

A partial answer to this question is that [[w:tariff|tariff]]s on imported goods covered between 80 and 95 percent of all federal revenue up to 1860, and [[w:excise|excise taxes]] on only a few goods, such as whiskey, rum, tobacco, snuff and refined sugar, made up nearly all the rest.&lt;ref&gt;See the section on &quot;[[w:Excise tax in the United States#Historical background|Historical background]]&quot; in the Wikipedia article on &quot;[[w:Excise tax in the United States|Excise tax in the United States]]&quot;, accessed 2026-05-26.&lt;/ref&gt; The money raised from taxes on income during the Civil War, visible in Figure 3 above, were apparently negligible as a portion of federal revenue during the Barbary Wars and the Mexican-American War.  

==== Gulf of Tonkin Resolution: &quot;Betray the nation or do not get elected.&quot; ====

Regarding the [[w:Vietnam War|Vietnam War]], former president [[w:Dwight D. Eisenhower|Eisenhower]] wrote in his autobiography, which appeared in 1963 (he left the presidency 1961-01-20), that he had never communicated {{quote|

with a person knowledgeable in Indochinese affairs [including Vietnam] who did not agree that had elections been held as of the time of the fighting [leading to the defeat of the French in 1954], possibly 80 per cent of the population would have voted for the Communist [[w:Ho Chi Minh|Ho Chi Minh]].&lt;ref&gt;Eisenhower (1963, p. 372).&lt;/ref&gt;}}

[[w:Joseph McCarthy|Joseph McCarthy]], who had been elected to the US Senate in 1946 and &quot;experienced a meteoric rise in national profile beginning on February 9, 1950, when he gave a&quot; speech during which he said something like, &quot;The [[w:United States Secretary of State|State Department]] is infested with communists. I have here in my hand a list of 205—a list of names that were made known to the Secretary of State as being members of the Communist Party and who nevertheless are still working and shaping policy in the State Department.&quot; McCarthy's mostly baseless claims went largely unchallenged in the media, including accusing the Democrats of &quot;twenty years of treason&quot; for having been allied with the Soviet Union, which took the bulk of casualties during World War II. 

By the end of 1953 with (Republican) Eisenhower as president roughly 11 months, McCarthy was complaining about &quot;''21'' years of treason&quot;, complaining that Eisenhower was not sufficiently aggressive in rooting out the communists who McCarthy claimed were in the government.&lt;ref&gt;Fried (1997, p. 179).&lt;/ref&gt; 

Then the French were defeated by Vietnamese communists 1954-05-07 in the [[w:Battle of Dien Bien Phu|Battle of Dien Bien Phu]]. The [[w:1954 Geneva Conference|1954 Geneva Conference]], which had begun eleven days earlier, 1954-04-26, concluded 1954-07-21 with the &quot;Geneva Accords of 1954&quot;.&lt;ref&gt;The [[w:Battle of Dien Bien Phu|Battle of Dien Bien Phu]], 1954-05-07, effectively ended the [[w:First Indochina War|French Indochina War]]. This led to the [[w:1954 Geneva Conference|Geneva accords of 1954]], officially dated 1954-07-20 but actually signed the following morning. Those accords took effect on three different dates, July 27 and August 1 and 11 in three different sectors of Vietnam. See &lt;!--Agreement on the Cessation of Hostilities in Vietnam--&gt;{{cite Q|Q139676410}}&lt;/ref&gt; Those accords called for UN-supervised elections for July of 1956, when Eisenhower would presumably be campaigning for reelection. Eisenhower doubtless knew that he might lose his bid for re-election in 1956, if the Communist Ho Chi Minh won elections in July of that year. 

:''The consistent suppression of honest portrayal in the major media of that day of the perspective of anyone whom Eisenhower considered &quot;knowledgeable in Indochinese affairs&quot; gave him -- and his successors [[w:John F. Kennedy|Kennedy]], [[w:Lyndon B. Johnson|Johnson]], and [[w:Richard Nixon|Nixon]] -- the choice between betraying the nation or not getting elected.'' 

In this environment, the [[w:Operation 34A|US initiated a series of clandestine operations against North Vietnam]] including infiltrating CIA-recruited spies and supporting attacks against North Vietnam by South Vietnamese commandos.&lt;ref&gt;Paterson (2008).&lt;/ref&gt; This included a raid 1964-07-30 by South Vietnamese commandos on the island of Hòn Mê, roughly 300 km (180 miles) north of the [[w:Vietnamese Demilitarized Zone|Vietnamese Demilitarized Zone]] in the [[w:Gulf of Tonkin|Gulf of Tonkin]], covered by [[w:DESOTO patrol|US naval vessels]] patrolling in that area. Then during a dark and stormy night six days later, US naval vessels opened fire on radar snow, and President Johnson requested and received Congressional approval of the [[w:Gulf of Tonkin Resolution|Gulf of Tonkin Resolution]]; then-[[w:United States Secretary of Defense|US Secretary of Defense]] [[w:Robert McNamara|McNamara]] claimed those attacks were &quot;unprovoked&quot;.&lt;ref&gt;Karnow (1983, p. 375). See also the section on [[w:Gulf of Tonkin Resolution#Congress votes|Congress votes]]&quot; in the Wikipedia article on [[w:Gulf of Tonkin Resolution|Gulf of Tonkin Resolution]], accessed 2026-05-14.&lt;/ref&gt;

In this media environment, only two officials in the US Congress voted against the Gulf of Tonkin Resolution: [[w:Ernest Gruening|Ernest Gruening]] (D-AK) and [[w:Wayne Morse|Wayne Morse]] (D-OR). Gruening lost in his next primary campaign to [[w:Mike Gravel|Mike Gravel]], and Morse lost in his next general election campaign to [[w:Bob Packwood|Bob Packwood]]. These results support the previous claim that the major media give politicians the choice: 

:''Betray the nation, or do not get elected.''

That resolution became the primary authorization for the US war in Vietnam until Congress ended the funding. 

==== Was the Vietnam War lost in Washington or by media biases? ====

[[w:John Mueller|John Mueller]], prolific author, Professor Emeritus of international relations at [[w:Ohio State University|Ohio State University]] and Senior Fellow at the [[w:Cato Institute|Cato Institute]], said that the most effective thing the US did to win the [[w:Cold War|Cold War]] was —

:''nothing'': 

Between the [[w:Fall of Saigon|Fall of Saigon]] in 1975 and the inauguration of [[w:Ronald Reagan|Ronald Reagan]] as President of the US, the US &quot;went into a sort of containment funk: it effectively adopted a policy of complacency (or perhaps of appeasement) as it watched from the sidelines as the Soviet Union … opportunistically gathered a set of Third World countries into its imperial embrace: Angola in 1976, Mozambique and Ethiopia in 1977, South Yemen and Afghanistan in 1978, Grenada and Nicaragua in 1979.&quot;&lt;ref&gt;Mueller (2021,  p. 59).&lt;/ref&gt; Nearly all became major economic and political drains on the Soviets with Afghanistan being the worst. And their Warsaw Pact allies in Eastern Europe became a severe economic drain and psychic problem.&lt;ref&gt;Mueller and Graves (2023).&lt;/ref&gt; 

President Reagan, inaugurated 1981-01-20, had a very different vision of the role of the US in foreign relations from his predecessor, [[w:Jimmy Carter|Jimmy Carter]]. In 1983-06-21 Reagan insisted, &quot;We cannot permit the Soviet-Cuban-Nicaraguan axis to take over Central America&quot;, because the consequences would include &quot;a tidal wave of refugees ... 'feet people' ... swarming into our country.&quot;&lt;ref&gt;Clines (1983).&lt;/ref&gt; 

Other sources&lt;ref&gt;e.g., Andersen (2006, Part II).&lt;/ref&gt; insist the opposite, that the vast majority of deaths in Central America during the Reagan years were poor humans petitioning nonviolently for a redress of grievances, suppressed by terrorist / death squads supported by the Reagan administration largely in violation of laws passed by Congress and signed by President Reagan. On 1986-10-05 [[w:Corporate Air Services HPF821|a Nicaraguan soldier with a surface to air missile shot down a C-123]] cargo aircraft carrying supplies to the Contra roughly 35 miles (56 km) north of Costa Rica. Documents found in the wreckage and a confession by the sole survivor led to the [[w:Iran–Contra affair|Iran-Contra hearings]] the following year, during which Lt. Col. [[w:Oliver North|Oliver North]] insisted, &quot;We didn't lose the war in Vietnam ..., we lost it in this city.&quot;&lt;ref&gt;Andersen (2006, p. 137). See also, Wikipedia, &quot;[[w:Stab-in-the-back myth|Stab-in-the-back myth]]&quot;, accessed 2026-05-13.&lt;/ref&gt; 

The previous section on the &quot;Gulf of Tonkin Resolution&quot; provides an alternative narrative of the Vietnam War: If as Eisenhower claimed, &quot;possibly 80 per cent of the [Vietnamese] population would have voted for the Communist [[w:Ho Chi Minh|Ho Chi Minh]]&quot; if elections had been held there, it's hard to imagine how anyone else could have won without aggressive action that actually ''improved'' the lives of Vietnamese peasants in the South. US-led efforts there were officially designed to win &quot;[[w:Hearts and Minds (Vietnam War)|Hearts and Minds]]&quot; but were implemented with such coercion that the result was the opposite. A cynic might say that it is hard to win people's hearts and minds by killing them. 

====Richard Barlow and nuclear proliferation====

There is also documentation that the US helped Pakistan get nuclear weapons and destroyed the career of an intelligence analyst, [[w:Richard Barlow (intelligence analyst)|Richard Barlow]], for telling his managers they should not lie to Congress about it. Barlow has insisted that neither Pakistan nor North Korea would have nuclear weapons and Iran would not have a nuclear weapons program today, if the US had followed its own laws. Barlow’s claims, including his punishment by administration officials, have been reported in major media outlets&lt;ref&gt;e.g., Stein (2013). See also Wikipedia, &quot;[[w:Richard Barlow (intelligence analyst)|Richard Barlow (intelligence analyst)]]&quot;, accessed 2026-05-06.&lt;/ref&gt; but not in a way that would seriously limit the ability — and need — for administration officials to lie to Congress. 

If Barlow's claims are accurate, it suggests that US government officials violated US obligations under the [[w:Treaty on the Non-Proliferation of Nuclear Weapons|Non-Proliferation Treaty]] (NPT).&lt;ref&gt;Per the [[w:Treaty Clause|Treaty Clause]] of the US Constitution, a treaty negotiated by the President and approved by the Senate has &quot;the force of federal law.&quot;&lt;/ref&gt; 

==== Nayirah testimony and the 1990-1991 Gulf War ====

A more recent example is the 1990-10-10 testimony by [[w:Nayirah testimony|Nayirah al-Ṣabaḥ to the US Congressional Human Rights Caucus]], two months after the Iraqi invasion of Kuwait. She claimed to have seen Iraqi soldiers taking premature babies out of incubators in a maternity ward before looting the incubators and leaving the babies to die on the floor after the Iraqi invasion of Kuwait; she said she had been a volunteer nurse in the hospital at that time. 

The failure of journalists, including with the ''[[w:NBC Nightly News|NBC Nightly News]]'', to adequate check facts behind this and other atrocity stories helped convince the US public to support the US-led invasion of Iraq in 1990-1991. Nayirah's statements were widely publicized and cited numerous times in the United States Senate and by American president George H. W. Bush to contribute to the rationale for pursuing military action against Iraq. It was later revealed that she was the daughter of Kuwaiti ambassador to the US, [[w:Saud Nasser Al-Saud Al-Sabah|Saud Nasser Al-Saud Al-Sabah]], &quot;Reps. [[w:Tom Lantos|Tom Lantos]] and [[w:John Porter (Illinois politician)|John Edward Porter]], who sponsored the congressional hearings, had started a group called the Congressional Human Rights Foundation that had received $50,000 from Citizens for a Free Kuwait, as well as free office space in [[w:Hill &amp; Knowlton|Hill and Knowlton]]'s Washington headquarters&quot;,&lt;ref&gt;Rowse (1992).&lt;/ref&gt; and the public relations firm Hill and Knowlton had made a video while coaching her rehearsing her perjury and used that to prepare a video press release &quot;that eventually reached a total audience of about thirty-five million&quot;, 14 percent of the [[w:Demographic history of the United States|US population of 249 million per the census then in process]], with portions aired on the ''[[w:NBC Nightly News|NBC Nightly News]]'' the night after the testimony.&lt;ref&gt;Andersen (2006, pp. 170-171).&lt;/ref&gt; 

==== 1998 Embassy bombings and September 11 ====

As another example, there is substantial documentation available today that [[1998 Embassy bombings and September 11|the suicide mass murders of September 11, 2001]], likely would not have occurred if the US had treated the 1998 bombings of the US embassies in Kenya and Tanzania as law enforcement issues. Muslim clerics all over the world initially condemned those acts. Al-Qaeda was dead. Their funding had largely dried up. And bin Laden was scheduled to be extradited the following month to Saudi Arabia to be prosecuted for treason, where he would likely have been convicted and executed. Mayer (2008, p. 114) claimed those embassy bombings were motivated as retaliation for US support for torture.&lt;ref&gt;For more on torture, see the the section on [[#Make media responsible for harms|Make media responsible for harms]] below.&lt;/ref&gt; 

But it seemed questionable at best whether major media executives in the US would have given favorable coverage to such a diplomatic solution. Instead, the US bombed a pharmaceutical plant in Sudan and al-Qaeda training camps in Afghanistan. Then Muslim public opinion turned 180 degrees to conclude, &quot;Bin Laden is right: The US ''is'' an evil empire.&quot; The US became bin Laden’s only indispensable ally, according to the CIA agent responsible for tracking bin Laden at that time.&lt;ref&gt;Scheuer (2004, p. xv).&lt;/ref&gt; Leading Saudis started supporting al-Qaeda, including some working for the Saudi embassy and consulates in the US. Only one country seems to have been involved in the preparations for the September 11 attacks, and that was Saudi Arabia. But Saudis were friends of the Bush family, and a crisis is a terrible thing to waste.&lt;ref&gt;Romer (2009).&lt;/ref&gt; 

:''Did the US invade Afghanistan and Iraq on grounds that senior journalists and leading media executives should have known at the time were questionable and likely fraudulent — to the detriment of nearly everyone except the &quot;people&quot; who control most of the money for the media?'' 
:In particular, was Iraqi president [[w:Saddam Hussein|Saddam Hussein]] really a bigger threat to the US after he invaded Kuwait in 1990 or after the [[w:September 11 attacks|suicide mass murders of September 11, 2001]] than he was during the 1980s, when the US supported him [[w:Iran-Iraq War|killing Iranians]] or [[w:Anfal campaign|his own native Kurds]]? 

On 2003-05-29 [[w:BBC|BBC]] journalist [[w:Andrew Gilligan|Andrew Gilligan]] reported that the [[w:Tony Blaire|Blair government]] had &quot;sexed up&quot; [[w:September Dossier|intelligence reports]] issued the previous September to justify supporting the 2003-03-20 [[w:Iraq War|US-led invasion of Iraq]], two months before Gilligan's report. This led to the [[w:Hutton Inquiry|Hutton Inquiry]], which led to the resignations of Gilligan and the BBC's chairman and the firing of the BBC's director-general. However, the British public expressed so many reservations about the Hutton Inquiry that a follow-up investigation was ordered in 2009. This became the &quot;[[w:Iraq Inquiry|Iraq Inquiry]]&quot;, whose 2016-07-06 report essentially validated what Gilligan had said just over 13 years earlier. This provides one more example of the 1710 maxim of Jonathan Swift that, &quot;Falsehood flies, and truth comes limping after ... like a physician, who hath found out an infallible medicine, after the patient is dead.&quot;&lt;ref name=Swift/&gt;

====Ukraine war====

Page 1 of the 2023-05-04 edition of ''[[w:Le Monde Diplomatique|Le Monde Diplomatique]]'' carried a headline: 

:One year after the invasion of Ukraine: The media, vanguard of the war party,&lt;ref&gt;Halimi and Rimbert (2023) in the French-language original.&lt;/ref&gt;

consistent with Andersen (2006).

=== Make media responsible for harms ===

How might the world be different if injured parties could successfully sue major media for harms that result from government policies contradicted by evidence reasonably available to the major media outlets? 

For example, how might the world be different if: 

* combat veterans or their families could successfully sue major media outlets for biased reporting that stampede the nation into ill advised and counterproductive uses of military force on grounds that leading media personalities should have known at the time were questionable and likely fraudulent? 
* Vietnamese or Afghanis or Iraqis or Palestinians or victims in other countries could win similar lawsuits?
* immigrants could sue major media outlets for failing to publish reasonable summaries of the available research that says that immigrants on average are more entrepreneurial&lt;ref&gt;Aghion et al. (2022, pp. 266-270).&lt;/ref&gt; and no more likely to engage in criminal activities than native born, benefitting both the sending and receiving countries?&lt;ref&gt;The Wikipedia article on &quot;[[w:Immigration|Immigration]] cites research saying, &quot;that migration can be beneficial both to the receiving and sending countries. The academic literature provides mixed findings for the relationship between immigration and crime worldwide. ... [P]ublic perception often exaggerates the connection between immigration and crime, influenced by sensationalised media coverage and political rhetoric.&quot; The Wikipedia article on [[w:Immigration and crime|Immigration and crime]] notes that in some countries immigrants are over-represented in prison populations due to violations of immigration law or anti-immigrant biases in criminal justice. The Wikipedia article on &quot;[[w:Sanctuary city|Sanctuary city]]&quot; says that, &quot;Some studies on the relationship between sanctuary status and crime have found that sanctuary policies either have no effect on crime or that sanctuary cities have lower crime rates and stronger economies than comparable non-sanctuary cities.&quot; All references 2026-05-26.&lt;/ref&gt; 
* humans tortured by the US could sue the major media for suppressing honest discussion of the research that documents that torture is more likely counterproductive? An important report of the efficacy of torture was published in 1631 by [[w:Friedrich Spee|Friedrich Spee]], a German Jesuit priest and professor. A few years earlier, the Duke of Brunswick had invited Spee and another famous Jesuit scholar to supervise a continuation of the torture of a confessed witch. The Jesuits had previously told the Duke, &quot;The Inquisitors are doing their duty. They are arresting only people who have been implicated by the confession of other witches.&quot; The Duke then led the Jesuits to a woman being stretched on the rack and asked her, &quot;You are a confessed witch. I suspect these two men of being warlocks. What do you say? Another turn of the rack, executioners.&quot; &quot;No, no!&quot; screamed the woman. &quot;You are quite right. I have often seen .. . They can turn themselves into goats, wolves ... Several witches have had children by them. ... The children had heads like toads and legs like spiders.&quot;&lt;ref&gt;Pinker (2011, pp. 138-139). Mannix (1964, pp. 134-135). Mackay ( 2009, p. 320).&lt;/ref&gt; Crudely similar comments about the counterproductive nature of torture were made by Generals [[w:Stanley McChrystal|Stanley McChrystal]] (2013) and [[w:David Petraeus|David Petraeus]],&lt;ref&gt;DePaulo (2008).&lt;/ref&gt; who held command positions in Iraq and Afghanistan. The major media in the US has provided ample coverage of, e.g., comments by Donald Trump supporting torture (McCarthy 2016), while largely suppressing honest discussion of the research on it. 

Might the world be safer and more prosperous if major media outlets and their executives and journalists could be successfully sued when their biased reporting have substantive negative consequences? Might [[w:Freedom of information|the public's right to receive diverse information]] be advanced in this way, recognizing that false information disseminated by major media outlets can lead to substantive harms, similar to &quot;[[w:Shouting fire in a crowded theater|shouting ''fire'' in a crowded theater]]&quot;, while the same information disseminated by minor outlets would ''not'' produce such harms? 

Lawsuits of this nature could be facilitated by &quot;group libel&quot; laws. Activists were working to pass such laws in the 1940s. By 1950 those campaigns had been abandoned, according to Barbas (2023).&lt;ref&gt;See also Calvert et al. (2023, pp. 178ff).&lt;/ref&gt; 

[[w:Yael Eisenstat|Yaël Eisenstat]] agrees that under [[w:Section 230|Section 230]] of Title 47 of the US Code, &quot;No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider.&quot; However, Eisenstat insists that [[Online platforms' effects on public health, safety and democracy|&quot;an interactive computer service&quot; ''can'' be held liable when their algorithms have substantive negative consequences]], as in the jury verdicts against Meta in New Mexico&lt;ref&gt;Allyn (2026).&lt;/ref&gt; and against Meta and Google in Los Angeles.&lt;ref&gt;McQue (2026).&lt;/ref&gt; She said, &quot;those technologies, if they are, in the end, contributing to an illegal activity or to harm, that's what we should be addressing. ... The ultimate goal is not to shut down every social media company. The ultimate goal is to figure out what a safer online experience looks like and what accountability looks like when something unsafe happens.&quot; 

=== in sum ===

You, dear reader, can help overcome these problems by talking, as suggested in the exercises below and the rest of this book. If you can help others become less angry and more willing to agree to disagree agreeably with others, that should reduce the risk of war and improve the prospects for progress on other major problems facing humanity today. 

==2. Training in nonviolent noncooperation for anyone willing to listen == 

A major driver of the current conflict between India and Pakistan is mistreatment of Muslims in India. Simulations of a nuclear war between India and Pakistan suggest that such a war would likely produce a nuclear autumn lasting years during which 40 percent of humanity would starve to death if they did not die of something else sooner. Over 90 percent of those would be in countries not involved in the nuclear exchange.&lt;ref&gt;Xia et al. (2022). See also Wikiversity, &quot;[[Responding to a nuclear attack]]&quot;, accessed 2026-05-05.&lt;/ref&gt;

The recent &quot;[[w:2025 India–Pakistan conflict|2025 India–Pakistan conflict]]&quot; was a response by India to violence in Indian-administered [[w:Kashmir|Kashmir]] by terrorists allegedly supported by Pakistan. India would have had much more difficulty justifying violent repression of ''nonviolent'' protests, especially if a more diverse media ecology gave such protests more and more sympathetic coverage. 

During the [[w:Great Depression|Great Depression]], ethnic Germans in the [[w:Sudetenland|Sudetenland]] region of [[w:Czechoslovakia|Czechoslovakia]] were harder hit by increasing trade barriers than their non-German neighbors. They were therefore more open to populist and extremist movements such as fascism, communism and German irredentism.&lt;ref&gt;Wikipedia, &quot;[[w:Sudetenland|Sudetenland]]&quot;, esp. the section on &quot;[[w: Sudetenland#Within the Czechoslovak Republic (1918–1938)|Within the Czechoslovak Republic (1918–1938)]]&quot;, accessed 2026-05-05.&lt;/ref&gt; If those ethnic Germans had used nonviolent noncooperation to highlight their grievances, and if Czechoslovakia at that time had had a substantially more diverse media system, it seems likely that they could have gotten reasonable redress of grievances. If so, it would have been harder for Hitler to use that as an excuse to invade Czechoslovakia, as he did in 1938.&lt;ref&gt;Wikipedia, &quot;[[w:Occupation of Czechoslovakia (1938–1945)|Occupation of Czechoslovakia (1938–1945)]]&quot;, accessed 2026-05-05.&lt;/ref&gt; 

An ideal settlement of the current Russo-Ukraine war might include training in nonviolent noncooperation made more effective through a more diverse media culture as suggested above. A substantial portion of the Ukrainian population, especially the Ukrainian military, are reported to be vicious anti-Russian Nazis, and the Ukrainian government has outlawed many uses of non-Ukrainian languages, especially Russian.&lt;ref&gt;Horton (2024).&lt;/ref&gt; A campaign of nonviolent noncooperation with a vigorous, diverse adversarial press would likely make it harder for Ukraine to continue any persecution of Russian speakers. It would also make it harder for major media in the US and Western Europe to suppress honest discussion of anti-Russian racism in Ukraine. Swanson (2022) said that the [[w:Baltic states|Baltic states]] have implemented such training in preparations for a possible Russian invasion; they might be asked to support such training in Ukraine (and elsewhere).&lt;ref&gt;Swanson (2022).&lt;/ref&gt; 

Organizations offering training in [[w:Nonviolent resistance|nonviolent noncooperation]] include [[w:Nonviolence International|Nonviolence International]] and the [[w:Highlander Research and Education Center|Highlander Research and Education Center]]. 

=== Civil resistance deters fracking ===

Duhamel (2013) claimed that well-advertised planning and training in nonviolent noncooperation helped deter oil companies from attempting hydraulic fracturing in [[w:Quebec|Quebec Province]] in [[w:Canada|Canada]]. Deterring a foreign invasion is different, but the same principle should apply: It's clear from many sources that elites consider nonviolence a threat; it's a felony to teach nonviolence to someone whom the US State Department claims supports a &quot;foreign terrorist organization&quot;, discussed in the next section.  

=== Life in prison for teaching nonviolence ===

Per the US Supreme Court decision in ''[[w:Holder v. Humanitarian Law Project|Holder v. Humanitarian Law Project]]'' (2010), teaching nonviolence to anyone whom the US State Department claims supports a foreign terrorist organization is &quot;[[w:Providing material support for terrorism|providing material support for terrorism]]&quot;, which is a felony under the USA [[w:Patriot Act|Patriot Act]] of 2001. Moreover, if the State Department claims that the death of any &quot;person&quot; resulted from the activities of the designated foreign terrorist organization, the penalty can be life in prison, where &quot;person&quot; is defined in the Patriot Act as &quot;any individual or entity capable of holding a legal or beneficial interest in property&quot;.&lt;ref&gt;The treatment of [[w:Sami Al-Arian|Sami Al-Arian]] is worth noting in discussing the Patriot Act. Al-Arian is a Kuwaiti-born political activist of Palestinian origin, who earned a doctorate in Electrical Sciences and Systems Engineering at [[w:North Carolina State University|North Carolina State]] in 1985 and taught computer engineering at [[w:University of South Florida|University of South Florida]] (USF) beginning in 1986. He was granted permanent resident status in 1989. In 1993 he earned a Distinguished Teacher Award as a tenured associate professor at USF. He was an [[w:imam|imam]] in a local [[w:mosque|mosque]] and led in other initiatives to promote dialogue and public policy initiatives between the West and Middle East. On September 26, 2001, he appeared on ''[[w:The O'Reilly Factor|The O'Reilly Factor]]'' where he was confronted with a 1988 recording of him shouting &quot;death to Israel&quot;. Al-Arian replied that &quot;Death to Israel&quot; meant &quot;death to occupation, ... apartheid, ...oppression,&quot; whereupon O'Reilly cut him off and called for the [[w:Central Intelligence Agency|Central Intelligence Agency]] to investigate him. Al-Arian spent most of the next 14 years between that 2001 interview and 2015 in detention, much of it in solitary confinement. This period included a 2005 trial that ended with acquittal on 8 counts and a hung jury on another 9. In 2015 he was deported to Turkey. In 2017, he founded the Center for Islam and Global Affairs at [[w:Istanbul Sabahattin Zaim University|Istanbul Sabahattin Zaim University]] in Istanbul, Turkey, which he directs. What has been the impact of treatment of Al-Arian on the well-being of the bottom 99 percent of the US and world population?&lt;/ref&gt; 

How did these provisions get written into the Patriot Act? 

That's a question that deserves research, perhaps by asking elected officials in the US Congress and lobbying for their repeal. A speculation consistent with the thesis of this book is that nonviolence terrifies those who control most of they money for the media, because it threatens their ability to get their security forces to follow orders.

==3. Forbid uses of force beyond one’s own borders and covert interference in foreign countries ==

:''[[w:Si vis pacem, para bellum|If you want peace, prepare for war.]]''
:  -- ''[[w:De Re Militari|De Re Militari]]'' by [[w:Publius Flavius Vegetius Renatus|Publius Flavius Vegetius Renatus]] (fourth or fifth century AD)

The record of history is now clear: Those who prepared for war often got war initiated when one party claimed they were being attacked or about to be attacked and believed they would fare better by attacking. Sometimes this occurred when the media environment convinced leaders that their political futures required them to clandestinely provoke foreign entities to do things that could then be denounced as unprovoked to justify military escalation, as mentioned in the previous section.  

Samuelson (2025) summarized quantitative analyses of 60 insurgencies since World War II, whose findings included the complete absence of success with counterinsurgencies without large force ratios (at least four, and most often more than ten, times the force of the insurgents) and without &quot;providing a path toward peaceful addressing of grievances&quot;. He also noted that, &quot;Brutality toward the civilian population ... tends to inflame the insurgency.&quot;&lt;ref&gt;Samuelson (2025) summarized Lawrence (2015).&lt;/ref&gt; His analysis gave a pessimistic prognosis for the [[w:Gaza war|Gaza war]] that began 2023-10-07. His conclusions are consistent with the history of the current [[w:Russo-Ukrainian war|Russo-Ukrainian war]], the [[w:Vietnam War|Vietnam War]], the [[w:Graveyard of empires|First, Second, and Third Anglo-Afghan Wars (1839-1919), the Soviet-Afghan War (1979–1989), the US-led War in Afghanistan (2001–2021)]], the 2001-2011 [[w:Iraq War|Iraq War]], and others. 

A key point is that invaders often to lose unless they enter with overwhelming force like Germany in the early stages of World War II: The [[w:Occupation of Czechoslovakia (1938–1945)|Czechoslovaks]], [[w:Invasion of Poland|Poles]], [[w:France during World War II|French]], and others were not prepared to fight the Germans, but the [[w:Soviet Union in World War II|Soviets]] were. [[w:Adolf Hitler|Hitler]] doubtless knew that the [[w:Switzerland during World War I and World War II|Swiss]] were prepared to fight, so he attacked other countries first. While fighting the [[w:Russo-Ukrainian war#Full-scale Russian invasion of Ukraine (2022)|Russian invasion]] that began 2022-02-24, [[w:Defense industry of Ukraine|Ukraine has developed]] military drones that are highly effective relative to the cost, as witnessed by sales of such to Gulf Arab states,&lt;ref&gt;Sharawi and Shapiro (2026).&lt;/ref&gt; illustrating the point that foreign invaders often encounter vastly more resistance than they expect -- and should expect highly effective resistance if they invade a country prepared to fight on their own territory. 

The rest of this section discusses weaknesses with standard deterrence theory. 

===Deterrence theory and nuclear Armageddon=== 

Standard [[w:Deterrence theory|deterrence theory]] assumes that one's opponents are rational and do not want [[w:Armageddon|Armageddon]]. The record of history summarized above raises questions about this assumption: In World War I, even the &quot;winners&quot; arguably lost more than they gained -- doubtless excepting a few merchants, who made fortunes from what they sold. Many of the other military decisions discussed above seem to have been driven more by the media than military necessity. 

Beyond that, at least some portions of the [[w:Islamic State|Islamic State]] reportedly violates this assumption, because it &quot;not only believes in the literal meaning of the coming Armageddon – it sees itself as its chief protagonist.&quot;&lt;ref&gt;Misra (2015).&lt;/ref&gt; Some [[w:Christian nationalism|Christian nationalists]] promoted to command positions by [[w:United States Secretary of Defense|US Secretary of Defense]] [[w:Pete Hegseth|Hegseth]] and President Trump also seem to believe that Armageddon might be desirable. On 2026-03-03 the [[w:Military Religious Freedom Foundation|Military Religious Freedom Foundation]] said they had received over 200 complaints from over 50 different US military installations with comments like, &quot;President Trump has been anointed by Jesus to light the signal fire in Iran to cause Armageddon and mark his return to Earth&quot;, per an email from one [[w:Non-commissioned officer|NCO]].&lt;ref&gt;Nick Mordowanec (2026).&lt;/ref&gt; With Hegseth holding monthly Christian worship services in the Pentagon during business hours,&lt;ref&gt;Black (2025), Mayes-Osterman (2025). See also the section on &quot;[[w:Pete Hegseth#Pentagon Christian worship services and &quot;biblically sanctioned war&quot;|Pentagon Christian worship services and &quot;biblically sanctioned war&quot;]] in the Wikipedia article on [[w:Pete Hegseth|Pete Hegseth]], accessed 2026-05-14.&lt;/ref&gt; this suggests that Hegseth could have appointed enough Christian nationalists to key positions to initiate nuclear attacks on Iran or Russia, claiming that President Trump had ordered such whether he had or not.&lt;ref&gt;The [[w:Gold Codes|Gold Codes]] carried in the &quot;[[w:nuclear football|nuclear football]]&quot; required by the [[w:Permissive action link|permissive action link]]s would ''not'' prevent Hegseth and a few others appointed by him from initiating nuclear Armageddon, according to Ellsberg, who had been a nuclear war planner for presidents Eisenhower, Kennedy, Johnson, and Nixon, before releasing the ''[[w:Pentagon Papers|Pentagon Papers]]''. Ellsberg (2017, p. 69) insisted that the security provided by those Gold Codes were a hoax, because otherwise a single nuclear detonation on Washington, DC, when both the president and vice president were in town &quot;would would definitively block any authorized, coordinated nuclear response to that or any subsequent nuclear attack.&quot;&lt;/ref&gt; 

The biggest risk today may be the risk of [[w:Nuclear holocaust|nuclear Armageddon]], which seems on average to grow over time consistent with experience with &quot;[[w:system accidents|system accidents]]&quot; in other fields: It is naive to assume that any system as complex as military command, control and communications systems never fail. And managers of complex systems subject to rare, catastrophic failures &quot;learn&quot; from experience that they can take ever greater risks, because they have &quot;safely&quot; done so in the past — until there is a catastrophe:&lt;ref&gt;Kahneman and Klein (2009) found that expert intuition, when it exists, is learned from frequent, rapid, high quality feedback. With anything nuclear, mishaps are so rare that managers develop &quot;expert intuition&quot; that they can &quot;safely&quot; ignore safety concerns -- until there is a catastrophe. See also Sagan (1993).&lt;/ref&gt; 

Veterans for Peace (2022) recommend global reduction and rapid elimination of nuclear weapons &quot;to reduce the real risk of nuclear confrontation through accidental launch or miscalculated escalation&quot;. 

==== National security tariffs ====

Free trade agreements supported by the [[w:World Trade Organization|World Trade Organization]] allow exemptions for national security and other objectives. [[Responding to a nuclear attack|Even a minor nuclear war between India and Pakistan would have a negative impact on the entirety of humanity]]. It might therefore be sensible for parties to the [[w:Treaty on the Prohibition of Nuclear Weapons|Treaty on the Prohibition of Nuclear Weapons]] (TPNW) to institute gradually increasing tariffs on nuclear weapon states, not so great as to seriously impact the economy of the nation applying such tariffs but aggressive enough to gradually wean their economy from reliance on trade with nuclear-weapon states that refuse to support the TPNW.

===Research on the effectiveness of deterrence and implications=== 

Lebow and others have provided substantial documentation of case studies claiming that leaders are often not rational, and deterrence based on threatening use of military force beyond one’s own borders has been ''as likely to provoke as prevent'' undesired behavior.&lt;ref&gt;Lebow (2025, 2024), Lebow et al. (2023).&lt;/ref&gt; The most obvious portions of this threat can be entirely eliminated by policies clearly and effectively forbidding use of force beyond one’s own borders. This can be signaled in at least three ways: 

* Eliminate all weapon systems like missiles and aircraft with a range of more than, e.g., a hundred miles or 200 kilometers with the possible exception of surveillance only aircraft that cannot be easily configured to carry [[w:Materiel#Military|ordnance]], e.g., explosives. Similarly eliminate nuclear weapons, which few if any countries would want to use for military defense inside their own borders. 

* Supply a national guard and reserves with weapons, training, and rules of engagement that prohibit projecting force beyond one’s own borders. Train them also in development and use of improvised explosive devices and other tactics and devices like low cost military drones. 

:Afghanistan is said to be the &quot;[[w:Graveyard of empires|Graveyard of empires]]&quot;. They defeated the British three times (1839–1842, 1878–1880, 1919), the Soviet Union (1979–1989), and the US (2001–2021). Each victory came with foreign supplies, but any foreign troops helping Afghanis were primarily under the command of local leaders. 
:The [[w:2003 invasion of Iraq|2003 invasion of Iraq]] might have produced [[w:Nation-building|nation-building]] more like the experience of [[w:Nation-building#Germany and Japan after World War II|Germany and Japan after World War II]] if the US had mandated a vigorous adversarial press instead of strict censorship, according to McChesney and Nichols.&lt;ref&gt;McChesney and Nichols (2010, Appendix II. Ike, MacArthur and the Forging of Free and Independent Press, pp. 241-254).&lt;/ref&gt; This claim by McChesney and Nichols was not endorsed by [[News from Germany 1900-1945 and implications for today#After the war in Germany vs. Iraq|University of British Columbia History professor Heidi Tworek]], who said the democratization efforts in Germany and Japan after World War II were more complicated than that implied by that brief discussion by McChesney and Nichols.&lt;ref&gt;The 2025-07-03 interview with Tworek is available at &quot;[[News from Germany 1900-1945 and implications for today]]&quot;, accessed 2026-05-14.&lt;/ref&gt; However, the research by Usher and Kim-Leffingwell (2022) and the related research on news deserts summarized in the preface to this ''[[Media Literacy and You]]'' book largely supports those claims by McChesney and Nichols.
:[[w:Defense industry of Ukraine|Ukraine has become a world leader in military drones]], many of which are dramatically cheaper than alternatives. Most of those have limited range but have been useful for reconnaissance and delivery of ordnance and improving targeting of, e.g., surface to air missiles. 
:[[w:Eliot A. Cohen|Eliot Cohen]], who served as a special advisor to [[w:United States Secretary of State|US Secretary of State]] [[w:Condoleezza Rice|Condoleezza Rice]] from 2007 to 2009, wrote, &quot;As the United States discovered in Iraq and Afghanistan, no matter how large, technologically advanced, and proficient an army is, motivated insurgents can still inflict casualties in the tens of thousands.&quot;&lt;ref&gt;Cohen (2022), cited from Horton (2024, p. 1026).&lt;/ref&gt; Cohen recommended we &quot;Arm the Ukranians now&quot;. Horton said that the neoconservatives learned from Iraq War II and Afghanistan that the US &quot;should fight like those who defeated them.&quot;&lt;ref&gt;Horton (2024, p. 1026).&lt;/ref&gt; 
:Leading economist [[w:Jeffrey Sachs|Jeffrey Sachs]] addressed the European Parliament 2025-02-19, claiming that the tragedy that befell Serbia in 1999 and subsequent US uses of force in Iraq and Syria, plus wars in Africa including Syria, Somalia and Libya and the current wars in Ukraine and the Israel-Hamas war, &quot;are to a very significant extent the result of deeply misguided US policies.&quot;&lt;ref&gt;Sachs (2025-02).&lt;/ref&gt; He said that Europe should craft its own foreign and military policies, independent of the US. ''[[w:Le Monde Diplomatique|Le Monde Diplomatique]]'' noted that Sachs' speech has circulated among social media since ''but has yet to be seriously discussed by major European media.''&lt;ref&gt;Sachs (2025-04; emphasis added).&lt;/ref&gt; 

* Change the laws of government secrecy so government officials cannot secretly interfere in the internal affairs of foreign countries or otherwise project force outside their own borders. This might be achieved in the US in part by requiring anyone with information about questionable actions by government officials to provide such documentation to one or more congressional oversight bodies while also allowing any current or former government employee or contractor to file suit in any US federal jurisdiction if they feel they have been punished for refusing to support questionable activities. In addition, federal judges should be authorized to subpoena classified government documents that may be relevant to any case in their jurisdiction and declassify them subject to appellate review if they believe the national interest would be better served by declassification. 

:If the law is changed without a substantive [[#1. Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content.|citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference]], as discussed above, the change could be merely cosmetic and unconvincing to local public officials and potential adversaries. 
:Connelly (2023) noted that US government secrecy has in the past encouraged administration officials to do things to provoke actions by foreign entities that can then be denounced as “unprovoked” to stampede the US Congress and the public into supporting counterproductive uses of military force, as discussed above.&lt;ref&gt;See also Connelly et al. (2023).&lt;/ref&gt; A more diverse media culture should make it harder for administration officials to lie to the public and to Congress — and harder to punish government employees who tell their managers that they should not lie to Congress, as they reportedly did to [[#Richard Barlow and nuclear proliferation|Richard Barlow]], mentioned above. 
:The Barlow case and many others explain why the US should, e.g., give federal judges the authority to subpoena classified documents and declassify them if they believe the public good is better served from declassification than continued secrecy.&lt;ref&gt;See, e.g., the 2025-05-08 interview with Seth Stern and Lauren Harper discussing what the &quot;[[Freedom of the Press Foundation says...]]&quot;, Graves (2014), and [[w:Moynihan Commission on Government Secrecy|Moynihan Commission on Government Secrecy]], accessed 2026-05-06. Graves (2021) recommends &quot;Congressional Gold Medals for&quot; Barlow and whistleblowers.&lt;/ref&gt; 

These policies would make it hard for any foreign leader to justify an attack for multiple reasons: First, it would be difficult to convince their supporters that such an attack is necessary. Second, a rational foreign leader might be hesitant to invade a country that is prepared to fight a guerrilla war. Germany reportedly considered invading [[w:Switzerland during World War I and World War II|Switzerland during both World Wars I and II]] and decided against it in part because Switzerland had large, well-trained ready reserves, who were ready to fight. Belgium seemed to be an easier route.&lt;ref&gt;Documented in Wikipedia, &quot;[[w:Switzerland during World War I and World War II|Switzerland during World War I and World War II]]&quot;, accessed 2026-05-06. Switzerland also has many mountains, which make it easier to defend, but the capabilities of the Swiss military also influenced the German decision to avoid Switzerland.&lt;/ref&gt; Third, even if foreign invaders defeat the guerrillas, they should not assume that their invading forces would continue to follow orders. [[w:Rescue of the Danish Jews|Ninety-nine percent of Danish Jews reportedly survived World War II]] because of Danish noncooperation ''supported by a German diplomat''.&lt;ref&gt;Wikipedia, &quot;[[w:Rescue of the Danish Jews|Rescue of the Danish Jews]]&quot;, accessed 2026-05-06.&lt;/ref&gt; 

With policies like these in place, it would be hard for foreign leaders to convince their supporters of a need to attack, as [[w:2022 Russian invasion of Ukraine|Putin did when invading Ukraine in 2022]],&lt;ref&gt;The Wikipedia article on &quot;[[w:2022 Russian invasion of Ukraine|2022 Russian invasion of Ukraine]]&quot;, accessed 2026-05-06, includes a paragraph saying, 'In July 2021, Putin published an essay &quot;On the Historical Unity of Russians and Ukrainians&quot;, in which he called Ukraine &quot;historically Russian lands&quot; and claimed there is &quot;no historical basis&quot; for the &quot;idea of Ukrainian people as a nation separate from the Russians&quot;'. Putin was accused of promoting Russian imperialism, historical revisionism and disinformation. Writing in 2024, Michael McFaul and Robert Person described this essay as representing not only &quot;cynical propaganda&quot; but also Putin's &quot;deeply held and internalized beliefs&quot;. See the Wikipedia article for references supporting those claims.&lt;/ref&gt; as [[w:2025 India–Pakistan crisis|India did when attacking Pakistan in 2025]], and as [[w:Invasion of Poland|Hitler did when invading Poland in 1939]], to name only three examples. 

=== If we continue to base deterrence on threats === 

There are now calls for Europe to get their own nuclear weapons,&lt;ref&gt;Burgard (2025).&lt;/ref&gt; while Iran, Saudi Arabia, Turkey, South Korea and Taiwan have been suggested as other candidates for acquiring nuclear weapons should they feel a sufficient need.&lt;ref&gt;Ruehl (2024).&lt;/ref&gt; 

It is difficult to imagine how the number of nuclear weapon states could be increased without increasing the risks of a nuclear war, consistent with the discussion of &quot;[[w:system accident|system accident]]s&quot; earlier in this chapter.

Secondarily, intelligence services with information on political corruption including attempts to intimidate and murder journalists should not be allowed to keep that information secret: They should be required to find ways to leak that information to journalists. Such attacks on journalists in their own country should be exposed and prosecuted if the evidence seems likely to obtain a conviction. Intelligence services with information about such attacks in other countries should be required to find ways to leak it to competent journalists without identifying their sources and methods: Doing so would likely reduce political corruption worldwide and with that the risks of war. 

== Collateral damage ==

The research cited above supports the claim that, 

:''[[w:Collateral damage|Collateral damage]] that our designated enemies commit prove to us that they are subhuman or criminally misled.''
:''Meanwhile, collateral damage that we commit is unfortunate but necessary -- from our perspective. However, it proves to our designated enemies that we are subhuman or criminally misled.'' 

This observation supports this entire program of deterrence without threat: 
* Forbidding use of force beyond one’s own borders and covert interference in foreign countries would automatically reduce collateral damage. It would also avoid uses of force that seem not to contribute to broadly shared peace and prosperity, according to research cited above. 
* The effectiveness of nonviolent noncooperation rests in part on its near universal avoidance of collateral damage. 
* Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content should make it much harder for major media to convince the public to do things contrary to their best interests, like invading or interfering covertly in foreign countries. 

== Call for help == 

Do you, dear reader, know other serious research not cited herein that might improve this analysis? If yes, you can help improve this discussion by adding comments with citations -- or by adding such citation(s) to the &quot;Discuss&quot; page associated with this chapter, suggesting someone else revise the chapter appropriately. 

There are plenty of contrary claims in the major media, but the lead author of this chapter is not aware of any that are based on serious research. 

In the absence of such research, the current author finds it difficult to imagine any national defense policies that carry a greater risk of nuclear Armageddon than our current policies, as discussed in the next chapter of this book on ''[[Media Literacy and You]]'' on &quot;[[Media Literacy and You/Responding to a nuclear attack|Responding to a nuclear attack]]&quot;. That chapter, in sum, claims that the ''worst'' response to a nuclear attack would be nuclear response, because it would escalate a catastrophe killing millions of humans to one killing ''billions'', possibly 80 percent of humanity in a war between the US and Russia that lofts so much smoke from burning cities to the stratosphere where it covers the globe depressing crop yields for years during with 99 percent of the humans in the US, Europe and Russia would starve to death if they did not die of something else sooner. Moreover, the record of &quot;[[w:System accident|system accident]]s&quot; suggests that the chances of such a war before the end of this century is substantially greater than the 40 percent median estimate based on history mentioned in a presentation on &quot;[[Time to nuclear Armageddon]]&quot; delivered to the 2019 Joint Statistical Meetings. 

This chapter is being written in the hopes of inspiring action to improve the prospects for broadly shared peace and prosperity for the long term. 

== Exercises ==

1. Disconfirmation bias: Brainstorm your biggest concerns about a current or possible future war. 
:1.1. Select the one that is of greatest concern to you currently. 
::One issue that may not be a major concern for many but might elicit a broad consensus for action would be a campaign to ask elected officials in the US Congress to explain how we benefit from the provisions of the USA Patriot Act of 2001 that authorize [[#life in prison for teaching nonviolence|life in prison for teaching nonviolence]]. 
:1.2. Who are your designated enemies? 
:1.3. Research what your designated enemies are saying about your biggest concern.  
:1.4. Under what circumstances would you support what you see your designated enemies advocating or doing? 
::If you cannot see such circumstances, expand your research: Look for more sources that support your designated enemies. 

2. Interacting: Ask others if you can share what you've learned about that conflict. If they say, &quot;No&quot;, don't push it. If they agree, share what you've learned in a friendly supportive manner without saying that anything is &quot;true&quot;. 

::''Show me someone who knows the truth, and I will show you someone who is dangerous.''

:2.1. The primary goal in this is ''not'' to convince anyone that you are right and they are wrong but to lower the level of anger and increase the level of tolerance for dissenting views. 
:2.2. Another goal is to comfortably enjoy civil conversations of this nature, agreeing to disagree agreeably and building trusting relationships that support collaboration on issues of common concern. 
:2.3. After becoming adept at building collaborations on issues of common concern, you might consider teaching this important skill and approach to issues.  

3. Teaching: Each one teach two, as discussed in the section on &quot;[[Media Literacy and You#Text and self-help book and point of discuss|Text and self-help book and point of discuss]]&quot; in the preface to this book.

:''Humanity is one misunderstanding, one miscalculation away from nuclear annihilation. ... This is madness. We must reverse course.''
:  -- [[w:António Guterres|UN Secretary General António Guterres]]  (2022)&lt;ref&gt;Jacobsen (2024), BBC (2022).&lt;/ref&gt;

:This book is a combination instruction manual on [[w:Media literacy|media literacy]] and an invitation to you to support collaborative / crowd-sourced research on how to improve the world's understanding of media literacy and how to accelerate its understanding and use globally for the betterment of humanity. 

Part I of this book on ''[[Media Literacy and You]]'' discusses &quot;The media and political economy&quot;. Except in times of terror, massive lawlessness or war, most humans place a high priority on their financial situation, the primary focus of Part I. Part II on &quot;The media and war&quot; focuses on security concerns starting with this chapter on &quot;Deterrence without threat&quot;. 

== Introduction ==

Every individual and group has a right and an obligation to defend itself. Unfortunately, when most humans&lt;ref&gt;We distinguish here between &quot;humans&quot; and &quot;people&quot; or &quot;persons&quot;, because under current US law, corporations are &quot;people&quot; and money is speech, per the US Supreme Court decision in ''[[w:Citizens United v. FEC|Citizens United v. FEC]]'' (2010) and many other judicial rulings and US law such as the [[w:Patriot Act|Patriot Act]] of 2001.&lt;/ref&gt; think of defense, they often think of violent responses to provocations. 

However, there is a growing body of research documenting 

:(a) how most uses of violence are counterproductive, and 
:(b) there are usually nonviolent options to violence that would more effectively promote broadly shared peace and prosperity for the long term. 

This research is rarely discussed by major media outlets, because it would offend the &quot;people&quot;&lt;ref&gt;We put &quot;people&quot; in quotes in this essay, because that term includes corporations under current US law.&lt;/ref&gt; who control most of the money for the media: Nonviolence threatens their ability to get compliance from security forces. As a result, many elites prefer to use force to the detriment of the bottom 99 percent of humanity. As discussed below, a military posture that supports projecting force beyond one’s own borders may be as likely to ''provoke'' as ''prevent'' an attack.&lt;ref&gt;For example, Lebow (2025) cites some of his previous work with others to support the claim that large militaries have been &quot;more provocative than preventative in&quot; their effects. And Lebow (2024) insists that, &quot;Policymakers respond more instinctively than analytically in deciding that some policy is or is not in the national interest.&quot; See also Lebow et al. (2023).&lt;/ref&gt; 

This chapter outlines a 3-part strategy that research suggests would more likely lead to better outcomes for the vast majority of humans: 

# Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content. 
# Training in nonviolent noncooperation for anyone willing to listen. 
# Forbid uses of force beyond one’s own borders and covert interference in foreign countries. 

We now discuss each of these briefly. 

== 1. Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content. == 

It seems that

:''Primary drivers of every major conflict include differences between the media that the different parties find crecible.''

In a recent interview with [[w:Fordham University|Fordham University]] Professor Emerita of Communications Robin Andersen,&lt;ref name=Andersen&gt;&lt;!--Robin Andersen--&gt;{{cite Q|Q132982358}}&lt;/ref&gt; she agreed with this claim and added: 

:''We only have enemies of our very own making.''

The media are involved in this, because:  

:''The major media create the stage upon which politicians read their lines.''&lt;ref&gt;In 1791 James Madison, who represented part of Virginia in the US House of Representatives 1789-1801 and later became the 4th President of the US (1809-1819), said, &quot;Public opinion sets bounds to every government, and is the real sovereign in every free one.&quot; Quoted from the ''[[w:National Gazette|National Gazette]]'' (published 1791-1793) by Schmeller (2009, p. 36) and Sauer (2016, p. 5). Sauer described how the American Revolutionaries, especially the first four US presidents, planted stories in newspapers to build support for how they dealt with the [[w:Barbary corsairs|Barbary pirates]], who were seizing merchant ships, raiding European coastal towns and villages, and selling European captives into slavery. The first two US presidents, [[w:George Washington|Washington]] and [[w:John Adams|Adams]], used that support for protecting US shipping and citizens by paying tribute to government leaders in Morocco, Algeria, Tunisia, and Libya. The next two presidents, [[w:Thomas Jefferson|Jefferson]] and [[w:James Madison|Madison]], convinced Congress to fund a navy and marines to fight the [[w:Barbary Wars|Barbary Wars]]. This included the [[w:Battle of Derna (1805)|Battle of Derna]]  (April-May 1805), memorialized in the [[w:Marines' Hymn|Marines' Hymn]], which mentions actions &quot;to the shores of Tripoli&quot;. Sauer described how the policies were sold to the public via planted stories in the different partisan newspapers.&lt;/ref&gt; 

This works because (a) virtually everyone thinks they know more than they do ([[w:Overconfidence effect|overconfidence effect]]), and (b) virtually everyone prefers information and sources consistent with preconceptions ([[w:confirmation bias|confirmation bias]]). 

Also, in many, perhaps all, countries, the primary constituency for foreign and military policy is the people with foreign business interests. Many of these people also control substantial portions of the money for the media, which have too often encourage questionable and counterproductive uses of military force.&lt;ref&gt;If we [[w:follow the money|follow the money]], we might find that &quot;watchdogs generally protect the people who feed them&quot;, as discussed in the 2025-09-25 interview with British journalist and media reform activist Dan Hind discussing how the British [[Media Reform Coalition challenges anti-democratic media bias in the UK]].&lt;/ref&gt; 

=== Examples === 

A leader in documenting the role of the media in armed conflict is Robin Andersen,&lt;ref&gt;e.g., Andersen (2006, 2026).&lt;/ref&gt; but she is not alone. For example, [[w:University of Denver|University of Denver]] journalism professor Kareem El Damanhoury&lt;ref name=Daman&gt;&lt;!--Kareem El Damanhoury--&gt;{{cite Q|Q113752441}}&lt;/ref&gt; has compared how [[w:Gaza Strip|Gaza]] has been framed differently by [[w:Al Jazeera Media Network|Al Jazeera]], the [[w:BBC|BBC]]&lt;ref&gt;El Damanhoury et al. (2025).&lt;/ref&gt; and [[w:Fox News|Fox]].&lt;ref&gt;El Damanhoury and Saleh (2024).&lt;/ref&gt;&lt;ref&gt;Some of El Damanhoury's work in this regard [[Differences between media outlets including coverage of Gaza|is reviewed in a 2025-11-20 interview with him]].&lt;/ref&gt; 

==== World War I ====

Andersen's (2006) ''A Century of Media, A Century of War'' begins with a discussion of &quot;The birth of war propaganda&quot; in &quot;The Great War and the Fight between Good and Evil&quot;.&lt;ref&gt;Andersen (2006, ch. 1)&lt;/ref&gt; 

A more detailed but compatible discussion of the media and [[w:World War I|World War I]] is given by [[w:John Maxwell Hamilton|John Maxwell Hamilton]]. Among other things, he said: {{quote|

The first iron law of propaganda is that only the enemy does it.&lt;ref&gt;Hamilton (2020, p. 642). See also the [[John Maxwell Hamilton on American propaganda|2025-12-11 interview with Hamilton]].&lt;/ref&gt;}} 

[[File:MB Walker - German bayoneting children - Life - July 25, 1915.png|thumb|left|Figure 1. Stories of German soldiers impaling children on their bayonets were widely reported during the war. However, no credible evidence was found to support these claims when questions were raised after the war.&lt;ref&gt;{{cite web|title=Alleged German atrocities: Bryce report|url=http://www.nationalarchives.gov.uk/pathways/firstworldwar/spotlights/p_alleged_german.htm|publisher=The National Archives|access-date=13 July 2014}}&lt;/ref&gt;]]

Andersen (2006, pp. 8-9) said, {{quote|

James Bryce, the former British ambassador to the United States, ... helped prepare a sixty-one page ''Report on the Committee on alleged German Outrages'', which was translated into thirty languages and was said to be based on twelve hundred depositions ... included gruesome and titillating details of how German soldiers publicly raped Belgian girls in the marketplace at Liege and bayonetted a two-year-old child. ... [A]fter the war a Belgian commission of inquiry found no evidence for any major accusation in the report. ...}}
{{quote|
German propagandists, on the other hand, ... &quot;bungled, because they were naïve: they thought the success of the war depended almost solely on military strategy and therefore they tended to neglect propaganda.&quot; ... Thus, when German soldiers shot some Allied nurses who had carried weapons, they admitted it openly. The Allies reported the incident as an atrocity and featured it in press propaganda. When French troops shot German nurses under similar circumstances, the Germans failed to exploit it.}} 

==== Jonathan Swift 1710 ====

This is not limited to World War I. In 1710, [[w:Jonathan Swift|Jonathan Swift]] reportedly said, &quot;Falsehood flies, and truth comes limping after ... like a physician, who hath found out an infallible medicine, after the patient is dead.&quot;&lt;ref name=Swift&gt;Excerpted from a line in [[Wikiquote:Jonathan Swift]] consulted 2026-04-13.&lt;/ref&gt;  

==== The Marines' Hymn ====

The [[w:Marines' Hymn|Marine Corps Hymn]] begins, {{quote|

From the Halls of Montezuma

To the shores of Tripoli;

We fight our country's battles

In the air, on land, and sea.}}

The &quot;[[w:Battle of Chapultepec|Halls of Montezuma]]&quot; refer to the [[w:Mexican–American War|Mexican–American War]], which was fought to expand slavery first into [[w:Texas|Texas]]  -- and supporters of slavery hoped that would help expand slavery further west. The &quot;[[w:Battle of Derna (1805)|shores of Tripoli]]&quot; were part of the [[w:Barbary Wars|Barbary Wars]], which were fought to reduce the need to pay (a) tribute to the [[w:Barbary Coast|Barbary or Berber]] states of [[w:Morocco|Morocco]], [[w:Algeria|Algeria]], [[w:Tunisia|Tunisia]], and [[w:Libya|Libya]] or (b) ransom to [[w:Barbary corsairs|Barbary pirates]], who were otherwise capturing Christians and selling them into slavery. 

Did the bottom 99 percent of the US population of that time benefit? Or did these wars (and any tribute and ransom paid by the US government before the Barbary wars) constitute a hidden transfer of wealth from the poor to the wealthy? 

A partial answer to this question is that [[w:tariff|tariff]]s on imported goods covered between 80 and 95 percent of all federal revenue up to 1860, and [[w:excise|excise taxes]] on only a few goods, such as whiskey, rum, tobacco, snuff and refined sugar, made up nearly all the rest.&lt;ref&gt;See the section on &quot;[[w:Excise tax in the United States#Historical background|Historical background]]&quot; in the Wikipedia article on &quot;[[w:Excise tax in the United States|Excise tax in the United States]]&quot;, accessed 2026-05-26.&lt;/ref&gt; The money raised from taxes on income during the Civil War, visible in Figure 3 above, were apparently negligible as a portion of federal revenue during the Barbary Wars and the Mexican-American War.  

==== Gulf of Tonkin Resolution: &quot;Betray the nation or do not get elected.&quot; ====

Regarding the [[w:Vietnam War|Vietnam War]], former president [[w:Dwight D. Eisenhower|Eisenhower]] wrote in his autobiography, which appeared in 1963 (he left the presidency 1961-01-20), that he had never communicated {{quote|

with a person knowledgeable in Indochinese affairs [including Vietnam] who did not agree that had elections been held as of the time of the fighting [leading to the defeat of the French in 1954], possibly 80 per cent of the population would have voted for the Communist [[w:Ho Chi Minh|Ho Chi Minh]].&lt;ref&gt;Eisenhower (1963, p. 372).&lt;/ref&gt;}}

[[w:Joseph McCarthy|Joseph McCarthy]], who had been elected to the US Senate in 1946 and &quot;experienced a meteoric rise in national profile beginning on February 9, 1950, when he gave a&quot; speech during which he said something like, &quot;The [[w:United States Secretary of State|State Department]] is infested with communists. I have here in my hand a list of 205—a list of names that were made known to the Secretary of State as being members of the Communist Party and who nevertheless are still working and shaping policy in the State Department.&quot; McCarthy's mostly baseless claims went largely unchallenged in the media, including accusing the Democrats of &quot;twenty years of treason&quot; for having been allied with the Soviet Union, which took the bulk of casualties during World War II. 

By the end of 1953 with (Republican) Eisenhower as president roughly 11 months, McCarthy was complaining about &quot;''21'' years of treason&quot;, complaining that Eisenhower was not sufficiently aggressive in rooting out the communists who McCarthy claimed were in the government.&lt;ref&gt;Fried (1997, p. 179).&lt;/ref&gt; 

Then the French were defeated by Vietnamese communists 1954-05-07 in the [[w:Battle of Dien Bien Phu|Battle of Dien Bien Phu]]. The [[w:1954 Geneva Conference|1954 Geneva Conference]], which had begun eleven days earlier, 1954-04-26, concluded 1954-07-21 with the &quot;Geneva Accords of 1954&quot;.&lt;ref&gt;The [[w:Battle of Dien Bien Phu|Battle of Dien Bien Phu]], 1954-05-07, effectively ended the [[w:First Indochina War|French Indochina War]]. This led to the [[w:1954 Geneva Conference|Geneva accords of 1954]], officially dated 1954-07-20 but actually signed the following morning. Those accords took effect on three different dates, July 27 and August 1 and 11 in three different sectors of Vietnam. See &lt;!--Agreement on the Cessation of Hostilities in Vietnam--&gt;{{cite Q|Q139676410}}&lt;/ref&gt; Those accords called for UN-supervised elections for July of 1956, when Eisenhower would presumably be campaigning for reelection. Eisenhower doubtless knew that he might lose his bid for re-election in 1956, if the Communist Ho Chi Minh won elections in July of that year. 

:''The consistent suppression of honest portrayal in the major media of that day of the perspective of anyone whom Eisenhower considered &quot;knowledgeable in Indochinese affairs&quot; gave him -- and his successors [[w:John F. Kennedy|Kennedy]], [[w:Lyndon B. Johnson|Johnson]], and [[w:Richard Nixon|Nixon]] -- the choice between betraying the nation or not getting elected.'' 

In this environment, the [[w:Operation 34A|US initiated a series of clandestine operations against North Vietnam]] including infiltrating CIA-recruited spies and supporting attacks against North Vietnam by South Vietnamese commandos.&lt;ref&gt;Paterson (2008).&lt;/ref&gt; This included a raid 1964-07-30 by South Vietnamese commandos on the island of Hòn Mê, roughly 300 km (180 miles) north of the [[w:Vietnamese Demilitarized Zone|Vietnamese Demilitarized Zone]] in the [[w:Gulf of Tonkin|Gulf of Tonkin]], covered by [[w:DESOTO patrol|US naval vessels]] patrolling in that area. Then during a dark and stormy night six days later, US naval vessels opened fire on radar snow, and President Johnson requested and received Congressional approval of the [[w:Gulf of Tonkin Resolution|Gulf of Tonkin Resolution]]; then-[[w:United States Secretary of Defense|US Secretary of Defense]] [[w:Robert McNamara|McNamara]] claimed those attacks were &quot;unprovoked&quot;.&lt;ref&gt;Karnow (1983, p. 375). See also the section on [[w:Gulf of Tonkin Resolution#Congress votes|Congress votes]]&quot; in the Wikipedia article on [[w:Gulf of Tonkin Resolution|Gulf of Tonkin Resolution]], accessed 2026-05-14.&lt;/ref&gt;

In this media environment, only two officials in the US Congress voted against the Gulf of Tonkin Resolution: [[w:Ernest Gruening|Ernest Gruening]] (D-AK) and [[w:Wayne Morse|Wayne Morse]] (D-OR). Gruening lost in his next primary campaign to [[w:Mike Gravel|Mike Gravel]], and Morse lost in his next general election campaign to [[w:Bob Packwood|Bob Packwood]]. These results support the previous claim that the major media give politicians the choice: 

:''Betray the nation, or do not get elected.''

That resolution became the primary authorization for the US war in Vietnam until Congress ended the funding. 

==== Was the Vietnam War lost in Washington or by media biases? ====

[[w:John Mueller|John Mueller]], prolific author, Professor Emeritus of international relations at [[w:Ohio State University|Ohio State University]] and Senior Fellow at the [[w:Cato Institute|Cato Institute]], said that the most effective thing the US did to win the [[w:Cold War|Cold War]] was —

:''nothing'': 

Between the [[w:Fall of Saigon|Fall of Saigon]] in 1975 and the inauguration of [[w:Ronald Reagan|Ronald Reagan]] as President of the US, the US &quot;went into a sort of containment funk: it effectively adopted a policy of complacency (or perhaps of appeasement) as it watched from the sidelines as the Soviet Union … opportunistically gathered a set of Third World countries into its imperial embrace: Angola in 1976, Mozambique and Ethiopia in 1977, South Yemen and Afghanistan in 1978, Grenada and Nicaragua in 1979.&quot;&lt;ref&gt;Mueller (2021,  p. 59).&lt;/ref&gt; Nearly all became major economic and political drains on the Soviets with Afghanistan being the worst. And their Warsaw Pact allies in Eastern Europe became a severe economic drain and psychic problem.&lt;ref&gt;Mueller and Graves (2023).&lt;/ref&gt; 

President Reagan, inaugurated 1981-01-20, had a very different vision of the role of the US in foreign relations from his predecessor, [[w:Jimmy Carter|Jimmy Carter]]. In 1983-06-21 Reagan insisted, &quot;We cannot permit the Soviet-Cuban-Nicaraguan axis to take over Central America&quot;, because the consequences would include &quot;a tidal wave of refugees ... 'feet people' ... swarming into our country.&quot;&lt;ref&gt;Clines (1983).&lt;/ref&gt; 

Other sources&lt;ref&gt;e.g., Andersen (2006, Part II).&lt;/ref&gt; insist the opposite, that the vast majority of deaths in Central America during the Reagan years were poor humans petitioning nonviolently for a redress of grievances, suppressed by terrorist / death squads supported by the Reagan administration largely in violation of laws passed by Congress and signed by President Reagan. On 1986-10-05 [[w:Corporate Air Services HPF821|a Nicaraguan soldier with a surface to air missile shot down a C-123]] cargo aircraft carrying supplies to the Contra roughly 35 miles (56 km) north of Costa Rica. Documents found in the wreckage and a confession by the sole survivor led to the [[w:Iran–Contra affair|Iran-Contra hearings]] the following year, during which Lt. Col. [[w:Oliver North|Oliver North]] insisted, &quot;We didn't lose the war in Vietnam ..., we lost it in this city.&quot;&lt;ref&gt;Andersen (2006, p. 137). See also, Wikipedia, &quot;[[w:Stab-in-the-back myth|Stab-in-the-back myth]]&quot;, accessed 2026-05-13.&lt;/ref&gt; 

The previous section on the &quot;Gulf of Tonkin Resolution&quot; provides an alternative narrative of the Vietnam War: If as Eisenhower claimed, &quot;possibly 80 per cent of the [Vietnamese] population would have voted for the Communist [[w:Ho Chi Minh|Ho Chi Minh]]&quot; if elections had been held there, it's hard to imagine how anyone else could have won without aggressive action that actually ''improved'' the lives of Vietnamese peasants in the South. US-led efforts there were officially designed to win &quot;[[w:Hearts and Minds (Vietnam War)|Hearts and Minds]]&quot; but were implemented with such coercion that the result was the opposite. A cynic might say that it is hard to win people's hearts and minds by killing them. 

====Richard Barlow and nuclear proliferation====

There is also documentation that the US helped Pakistan get nuclear weapons and destroyed the career of an intelligence analyst, [[w:Richard Barlow (intelligence analyst)|Richard Barlow]], for telling his managers they should not lie to Congress about it. Barlow has insisted that neither Pakistan nor North Korea would have nuclear weapons and Iran would not have a nuclear weapons program today, if the US had followed its own laws. Barlow’s claims, including his punishment by administration officials, have been reported in major media outlets&lt;ref&gt;e.g., Stein (2013). See also Wikipedia, &quot;[[w:Richard Barlow (intelligence analyst)|Richard Barlow (intelligence analyst)]]&quot;, accessed 2026-05-06.&lt;/ref&gt; but not in a way that would seriously limit the ability — and need — for administration officials to lie to Congress. 

If Barlow's claims are accurate, it suggests that US government officials violated US obligations under the [[w:Treaty on the Non-Proliferation of Nuclear Weapons|Non-Proliferation Treaty]] (NPT).&lt;ref&gt;Per the [[w:Treaty Clause|Treaty Clause]] of the US Constitution, a treaty negotiated by the President and approved by the Senate has &quot;the force of federal law.&quot;&lt;/ref&gt; 

==== Nayirah testimony and the 1990-1991 Gulf War ====

A more recent example is the 1990-10-10 testimony by [[w:Nayirah testimony|Nayirah al-Ṣabaḥ to the US Congressional Human Rights Caucus]], two months after the Iraqi invasion of Kuwait. She claimed to have seen Iraqi soldiers taking premature babies out of incubators in a maternity ward before looting the incubators and leaving the babies to die on the floor after the Iraqi invasion of Kuwait; she said she had been a volunteer nurse in the hospital at that time. 

The failure of journalists, including with the ''[[w:NBC Nightly News|NBC Nightly News]]'', to adequate check facts behind this and other atrocity stories helped convince the US public to support the US-led invasion of Iraq in 1990-1991. Nayirah's statements were widely publicized and cited numerous times in the United States Senate and by American president George H. W. Bush to contribute to the rationale for pursuing military action against Iraq. It was later revealed that she was the daughter of Kuwaiti ambassador to the US, [[w:Saud Nasser Al-Saud Al-Sabah|Saud Nasser Al-Saud Al-Sabah]], &quot;Reps. [[w:Tom Lantos|Tom Lantos]] and [[w:John Porter (Illinois politician)|John Edward Porter]], who sponsored the congressional hearings, had started a group called the Congressional Human Rights Foundation that had received $50,000 from Citizens for a Free Kuwait, as well as free office space in [[w:Hill &amp; Knowlton|Hill and Knowlton]]'s Washington headquarters&quot;,&lt;ref&gt;Rowse (1992).&lt;/ref&gt; and the public relations firm Hill and Knowlton had made a video while coaching her rehearsing her perjury and used that to prepare a video press release &quot;that eventually reached a total audience of about thirty-five million&quot;, 14 percent of the [[w:Demographic history of the United States|US population of 249 million per the census then in process]], with portions aired on the ''[[w:NBC Nightly News|NBC Nightly News]]'' the night after the testimony.&lt;ref&gt;Andersen (2006, pp. 170-171).&lt;/ref&gt; 

==== 1998 Embassy bombings and September 11 ====

As another example, there is substantial documentation available today that [[1998 Embassy bombings and September 11|the suicide mass murders of September 11, 2001]], likely would not have occurred if the US had treated the 1998 bombings of the US embassies in Kenya and Tanzania as law enforcement issues. Muslim clerics all over the world initially condemned those acts. Al-Qaeda was dead. Their funding had largely dried up. And bin Laden was scheduled to be extradited the following month to Saudi Arabia to be prosecuted for treason, where he would likely have been convicted and executed. Mayer (2008, p. 114) claimed those embassy bombings were motivated as retaliation for US support for torture.&lt;ref&gt;For more on torture, see the the section on [[#Make media responsible for harms|Make media responsible for harms]] below.&lt;/ref&gt; 

But it seemed questionable at best whether major media executives in the US would have given favorable coverage to such a diplomatic solution. Instead, the US bombed a pharmaceutical plant in Sudan and al-Qaeda training camps in Afghanistan. Then Muslim public opinion turned 180 degrees to conclude, &quot;Bin Laden is right: The US ''is'' an evil empire.&quot; The US became bin Laden’s only indispensable ally, according to the CIA agent responsible for tracking bin Laden at that time.&lt;ref&gt;Scheuer (2004, p. xv).&lt;/ref&gt; Leading Saudis started supporting al-Qaeda, including some working for the Saudi embassy and consulates in the US. Only one country seems to have been involved in the preparations for the September 11 attacks, and that was Saudi Arabia. But Saudis were friends of the Bush family, and a crisis is a terrible thing to waste.&lt;ref&gt;Romer (2009).&lt;/ref&gt; 

:''Did the US invade Afghanistan and Iraq on grounds that senior journalists and leading media executives should have known at the time were questionable and likely fraudulent — to the detriment of nearly everyone except the &quot;people&quot; who control most of the money for the media?'' 
:In particular, was Iraqi president [[w:Saddam Hussein|Saddam Hussein]] really a bigger threat to the US after he invaded Kuwait in 1990 or after the [[w:September 11 attacks|suicide mass murders of September 11, 2001]] than he was during the 1980s, when the US supported him [[w:Iran-Iraq War|killing Iranians]] or [[w:Anfal campaign|his own native Kurds]]? 

On 2003-05-29 [[w:BBC|BBC]] journalist [[w:Andrew Gilligan|Andrew Gilligan]] reported that the [[w:Tony Blaire|Blair government]] had &quot;sexed up&quot; [[w:September Dossier|intelligence reports]] issued the previous September to justify supporting the 2003-03-20 [[w:Iraq War|US-led invasion of Iraq]], two months before Gilligan's report. This led to the [[w:Hutton Inquiry|Hutton Inquiry]], which led to the resignations of Gilligan and the BBC's chairman and the firing of the BBC's director-general. However, the British public expressed so many reservations about the Hutton Inquiry that a follow-up investigation was ordered in 2009. This became the &quot;[[w:Iraq Inquiry|Iraq Inquiry]]&quot;, whose 2016-07-06 report essentially validated what Gilligan had said just over 13 years earlier. This provides one more example of the 1710 maxim of Jonathan Swift that, &quot;Falsehood flies, and truth comes limping after ... like a physician, who hath found out an infallible medicine, after the patient is dead.&quot;&lt;ref name=Swift/&gt;

====Ukraine war====

Page 1 of the 2023-05-04 edition of ''[[w:Le Monde Diplomatique|Le Monde Diplomatique]]'' carried a headline: 

:One year after the invasion of Ukraine: The media, vanguard of the war party,&lt;ref&gt;Halimi and Rimbert (2023) in the French-language original.&lt;/ref&gt;

consistent with Andersen (2006).

=== Make media responsible for harms ===

How might the world be different if injured parties could successfully sue major media for harms that result from government policies contradicted by evidence reasonably available to the major media outlets? 

For example, how might the world be different if: 

* combat veterans or their families could successfully sue major media outlets for biased reporting that stampede the nation into ill advised and counterproductive uses of military force on grounds that leading media personalities should have known at the time were questionable and likely fraudulent? 
* Vietnamese or Afghanis or Iraqis or Palestinians or victims in other countries could win similar lawsuits?
* immigrants could sue major media outlets for failing to publish reasonable summaries of the available research that says that immigrants on average are more entrepreneurial&lt;ref&gt;Aghion et al. (2022, pp. 266-270).&lt;/ref&gt; and no more likely to engage in criminal activities than native born, benefitting both the sending and receiving countries?&lt;ref&gt;The Wikipedia article on &quot;[[w:Immigration|Immigration]] cites research saying, &quot;that migration can be beneficial both to the receiving and sending countries. The academic literature provides mixed findings for the relationship between immigration and crime worldwide. ... [P]ublic perception often exaggerates the connection between immigration and crime, influenced by sensationalised media coverage and political rhetoric.&quot; The Wikipedia article on [[w:Immigration and crime|Immigration and crime]] notes that in some countries immigrants are over-represented in prison populations due to violations of immigration law or anti-immigrant biases in criminal justice. The Wikipedia article on &quot;[[w:Sanctuary city|Sanctuary city]]&quot; says that, &quot;Some studies on the relationship between sanctuary status and crime have found that sanctuary policies either have no effect on crime or that sanctuary cities have lower crime rates and stronger economies than comparable non-sanctuary cities.&quot; All references 2026-05-26.&lt;/ref&gt; 
* humans tortured by the US could sue the major media for suppressing honest discussion of the research that documents that torture is more likely counterproductive? An important report of the efficacy of torture was published in 1631 by [[w:Friedrich Spee|Friedrich Spee]], a German Jesuit priest and professor. A few years earlier, the Duke of Brunswick had invited Spee and another famous Jesuit scholar to supervise a continuation of the torture of a confessed witch. The Jesuits had previously told the Duke, &quot;The Inquisitors are doing their duty. They are arresting only people who have been implicated by the confession of other witches.&quot; The Duke then led the Jesuits to a woman being stretched on the rack and asked her, &quot;You are a confessed witch. I suspect these two men of being warlocks. What do you say? Another turn of the rack, executioners.&quot; &quot;No, no!&quot; screamed the woman. &quot;You are quite right. I have often seen .. . They can turn themselves into goats, wolves ... Several witches have had children by them. ... The children had heads like toads and legs like spiders.&quot;&lt;ref&gt;Pinker (2011, pp. 138-139). Mannix (1964, pp. 134-135). Mackay ( 2009, p. 320).&lt;/ref&gt; Crudely similar comments about the counterproductive nature of torture were made by Generals [[w:Stanley McChrystal|Stanley McChrystal]] (2013) and [[w:David Petraeus|David Petraeus]],&lt;ref&gt;DePaulo (2008).&lt;/ref&gt; who held command positions in Iraq and Afghanistan. The major media in the US has provided ample coverage of, e.g., comments by Donald Trump supporting torture (McCarthy 2016), while largely suppressing honest discussion of the research on it. 

Might the world be safer and more prosperous if major media outlets and their executives and journalists could be successfully sued when their biased reporting have substantive negative consequences? Might [[w:Freedom of information|the public's right to receive diverse information]] be advanced in this way, recognizing that false information disseminated by major media outlets can lead to substantive harms, similar to &quot;[[w:Shouting fire in a crowded theater|shouting ''fire'' in a crowded theater]]&quot;, while the same information disseminated by minor outlets would ''not'' produce such harms? 

Lawsuits of this nature could be facilitated by &quot;group libel&quot; laws. Activists were working to pass such laws in the 1940s. By 1950 those campaigns had been abandoned, according to Barbas (2023).&lt;ref&gt;See also Calvert et al. (2023, pp. 178ff).&lt;/ref&gt; 

[[w:Yael Eisenstat|Yaël Eisenstat]] agrees that under [[w:Section 230|Section 230]] of Title 47 of the US Code, &quot;No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider.&quot; However, Eisenstat insists that [[Online platforms' effects on public health, safety and democracy|&quot;an interactive computer service&quot; ''can'' be held liable when their algorithms have substantive negative consequences]], as in the jury verdicts against Meta in New Mexico&lt;ref&gt;Allyn (2026).&lt;/ref&gt; and against Meta and Google in Los Angeles.&lt;ref&gt;McQue (2026).&lt;/ref&gt; She said, &quot;those technologies, if they are, in the end, contributing to an illegal activity or to harm, that's what we should be addressing. ... The ultimate goal is not to shut down every social media company. The ultimate goal is to figure out what a safer online experience looks like and what accountability looks like when something unsafe happens.&quot;

You, dear reader, can help overcome these problems by talking, as suggested in the exercises below and the rest of this book. If you can help others become less angry and more willing to agree to disagree agreeably with others, that should reduce the risk of war and improve the prospects for progress on other major problems facing humanity today. 

==2. Training in nonviolent noncooperation for anyone willing to listen == 

A major driver of the current conflict between India and Pakistan is mistreatment of Muslims in India. Simulations of a nuclear war between India and Pakistan suggest that such a war would likely produce a nuclear autumn lasting years during which 40 percent of humanity would starve to death if they did not die of something else sooner. Over 90 percent of those would be in countries not involved in the nuclear exchange.&lt;ref&gt;Xia et al. (2022). See also Wikiversity, &quot;[[Responding to a nuclear attack]]&quot;, accessed 2026-05-05.&lt;/ref&gt;

The recent &quot;[[w:2025 India–Pakistan conflict|2025 India–Pakistan conflict]]&quot; was a response by India to violence in Indian-administered [[w:Kashmir|Kashmir]] by terrorists allegedly supported by Pakistan. India would have had much more difficulty justifying violent repression of ''nonviolent'' protests, especially if a more diverse media ecology gave such protests more and more sympathetic coverage. 

During the [[w:Great Depression|Great Depression]], ethnic Germans in the [[w:Sudetenland|Sudetenland]] region of [[w:Czechoslovakia|Czechoslovakia]] were harder hit by increasing trade barriers than their non-German neighbors. They were therefore more open to populist and extremist movements such as fascism, communism and German irredentism.&lt;ref&gt;Wikipedia, &quot;[[w:Sudetenland|Sudetenland]]&quot;, esp. the section on &quot;[[w: Sudetenland#Within the Czechoslovak Republic (1918–1938)|Within the Czechoslovak Republic (1918–1938)]]&quot;, accessed 2026-05-05.&lt;/ref&gt; If those ethnic Germans had used nonviolent noncooperation to highlight their grievances, and if Czechoslovakia at that time had had a substantially more diverse media system, it seems likely that they could have gotten reasonable redress of grievances. If so, it would have been harder for Hitler to use that as an excuse to invade Czechoslovakia, as he did in 1938.&lt;ref&gt;Wikipedia, &quot;[[w:Occupation of Czechoslovakia (1938–1945)|Occupation of Czechoslovakia (1938–1945)]]&quot;, accessed 2026-05-05.&lt;/ref&gt; 

In 1940, during World War II, Germany invade Denmark, which had previously declared neutrality. The Germans allowed [[w:1943 Danish Folketing election|Danish parliamentary elections in 1943]]. A Danish Nazi party won on 2.1% of the votes.&lt;ref&gt;{{cite web|title=Rigsdagsvalgene i Marts og April 1943|url=http://www.dst.dk/pukora/epub/upload/20217/valg1943.pdf|date=|publisher=Danmarks Statistic|accessdate=11 February 2021}}&lt;/ref&gt; [[w:Rescue of the Danish Jews|The Danes ignored Nazi orders to ship Danish Jews to the death camps.]] When the Germans decided to round up the Jews themselves, a German diplomat leaked those plans to the Danish government, and nearly all Danish Jews escaped to neutral Sweden; 99% of Denmark's Jewish population survived the Holocaust.

An ideal settlement of the current Russo-Ukraine war might include training in nonviolent noncooperation made more effective through a more diverse media culture as suggested above. A substantial portion of the Ukrainian population, especially the Ukrainian military, are reported to be vicious anti-Russian Nazis, and the Ukrainian government has outlawed many uses of non-Ukrainian languages, especially Russian.&lt;ref&gt;Horton (2024).&lt;/ref&gt; A campaign of nonviolent noncooperation with a vigorous, diverse adversarial press would likely make it harder for Ukraine to continue any persecution of Russian speakers. It would also make it harder for major media in the US and Western Europe to suppress honest discussion of anti-Russian racism in Ukraine. Swanson (2022) said that the [[w:Baltic states|Baltic states]] have implemented such training in preparations for a possible Russian invasion; they might be asked to support such training in Ukraine (and elsewhere).&lt;ref&gt;Swanson (2022).&lt;/ref&gt; 

Organizations offering training in [[w:Nonviolent resistance|nonviolent noncooperation]] include [[w:Nonviolence International|Nonviolence International]] and the [[w:Highlander Research and Education Center|Highlander Research and Education Center]]. 

=== Civil resistance deters fracking ===

Duhamel (2013) claimed that well-advertised planning and training in nonviolent noncooperation helped deter oil companies from attempting hydraulic fracturing in [[w:Quebec|Quebec Province]] in [[w:Canada|Canada]]. Deterring a foreign invasion is different, but the same principle should apply: It's clear from many sources that elites consider nonviolence a threat; it's a felony to teach nonviolence to someone whom the US State Department claims supports a &quot;foreign terrorist organization&quot;, discussed in the next section.  

=== Life in prison for teaching nonviolence ===

Per the US Supreme Court decision in ''[[w:Holder v. Humanitarian Law Project|Holder v. Humanitarian Law Project]]'' (2010), teaching nonviolence to anyone whom the US State Department claims supports a foreign terrorist organization is &quot;[[w:Providing material support for terrorism|providing material support for terrorism]]&quot;, which is a felony under the USA [[w:Patriot Act|Patriot Act]] of 2001. Moreover, if the State Department claims that the death of any &quot;person&quot; resulted from the activities of the designated foreign terrorist organization, the penalty can be life in prison, where &quot;person&quot; is defined in the Patriot Act as &quot;any individual or entity capable of holding a legal or beneficial interest in property&quot;.&lt;ref&gt;The treatment of [[w:Sami Al-Arian|Sami Al-Arian]] is worth noting in discussing the Patriot Act. Al-Arian is a Kuwaiti-born political activist of Palestinian origin, who earned a doctorate in Electrical Sciences and Systems Engineering at [[w:North Carolina State University|North Carolina State]] in 1985 and taught computer engineering at [[w:University of South Florida|University of South Florida]] (USF) beginning in 1986. He was granted permanent resident status in 1989. In 1993 he earned a Distinguished Teacher Award as a tenured associate professor at USF. He was an [[w:imam|imam]] in a local [[w:mosque|mosque]] and led in other initiatives to promote dialogue and public policy initiatives between the West and Middle East. On September 26, 2001, he appeared on ''[[w:The O'Reilly Factor|The O'Reilly Factor]]'' where he was confronted with a 1988 recording of him shouting &quot;death to Israel&quot;. Al-Arian replied that &quot;Death to Israel&quot; meant &quot;death to occupation, ... apartheid, ...oppression,&quot; whereupon O'Reilly cut him off and called for the [[w:Central Intelligence Agency|Central Intelligence Agency]] to investigate him. Al-Arian spent most of the next 14 years between that 2001 interview and 2015 in detention, much of it in solitary confinement. This period included a 2005 trial that ended with acquittal on 8 counts and a hung jury on another 9. In 2015 he was deported to Turkey. In 2017, he founded the Center for Islam and Global Affairs at [[w:Istanbul Sabahattin Zaim University|Istanbul Sabahattin Zaim University]] in Istanbul, Turkey, which he directs. What has been the impact of treatment of Al-Arian on the well-being of the bottom 99 percent of the US and world population?&lt;/ref&gt; 

How did these provisions get written into the Patriot Act? 

That's a question that deserves research, perhaps by asking elected officials in the US Congress and lobbying for their repeal. A speculation consistent with the thesis of this book is that nonviolence terrifies those who control most of they money for the media, because it threatens their ability to get their security forces to follow orders.

==3. Forbid uses of force beyond one’s own borders and covert interference in foreign countries ==

:''[[w:Si vis pacem, para bellum|If you want peace, prepare for war.]]''
:  -- ''[[w:De Re Militari|De Re Militari]]'' by [[w:Publius Flavius Vegetius Renatus|Publius Flavius Vegetius Renatus]] (fourth or fifth century AD)

The record of history is now clear: Those who prepared for war often got war initiated when one party claimed they were being attacked or about to be attacked and believed they would fare better by attacking. Sometimes this occurred when the media environment convinced leaders that their political futures required them to clandestinely provoke foreign entities to do things that could then be denounced as unprovoked to justify military escalation, as mentioned in the previous section.  

Samuelson (2025) summarized quantitative analyses of 60 insurgencies since World War II, whose findings included the complete absence of success with counterinsurgencies without large force ratios (at least four, and most often more than ten, times the force of the insurgents) and without &quot;providing a path toward peaceful addressing of grievances&quot;. He also noted that, &quot;Brutality toward the civilian population ... tends to inflame the insurgency.&quot;&lt;ref&gt;Samuelson (2025) summarized Lawrence (2015).&lt;/ref&gt; His analysis gave a pessimistic prognosis for the [[w:Gaza war|Gaza war]] that began 2023-10-07. His conclusions are consistent with the history of the current [[w:Russo-Ukrainian war|Russo-Ukrainian war]], the [[w:Vietnam War|Vietnam War]], the [[w:Graveyard of empires|First, Second, and Third Anglo-Afghan Wars (1839-1919), the Soviet-Afghan War (1979–1989), the US-led War in Afghanistan (2001–2021)]], the 2001-2011 [[w:Iraq War|Iraq War]], and others. 

A key point is that invaders often to lose unless they enter with overwhelming force like Germany in the early stages of World War II: The [[w:Occupation of Czechoslovakia (1938–1945)|Czechoslovaks]], [[w:Invasion of Poland|Poles]], [[w:France during World War II|French]], and others were not prepared to fight the Germans, but the [[w:Soviet Union in World War II|Soviets]] were. [[w:Adolf Hitler|Hitler]] doubtless knew that the [[w:Switzerland during World War I and World War II|Swiss]] were prepared to fight, so he attacked other countries first. While fighting the [[w:Russo-Ukrainian war#Full-scale Russian invasion of Ukraine (2022)|Russian invasion]] that began 2022-02-24, [[w:Defense industry of Ukraine|Ukraine has developed]] military drones that are highly effective relative to the cost, as witnessed by sales of such to Gulf Arab states,&lt;ref&gt;Sharawi and Shapiro (2026).&lt;/ref&gt; illustrating the point that foreign invaders often encounter vastly more resistance than they expect -- and should expect highly effective resistance if they invade a country prepared to fight on their own territory. 

The rest of this section discusses weaknesses with standard deterrence theory. 

===Deterrence theory and nuclear Armageddon=== 

Standard [[w:Deterrence theory|deterrence theory]] assumes that one's opponents are rational and do not want [[w:Armageddon|Armageddon]]. The record of history summarized above raises questions about this assumption: In World War I, even the &quot;winners&quot; arguably lost more than they gained -- doubtless excepting a few merchants, who made fortunes from what they sold. Many of the other military decisions discussed above seem to have been driven more by the media than military necessity. 

Beyond that, at least some portions of the [[w:Islamic State|Islamic State]] reportedly violates this assumption, because it &quot;not only believes in the literal meaning of the coming Armageddon – it sees itself as its chief protagonist.&quot;&lt;ref&gt;Misra (2015).&lt;/ref&gt; Some [[w:Christian nationalism|Christian nationalists]] promoted to command positions by [[w:United States Secretary of Defense|US Secretary of Defense]] [[w:Pete Hegseth|Hegseth]] and President Trump also seem to believe that Armageddon might be desirable. On 2026-03-03 the [[w:Military Religious Freedom Foundation|Military Religious Freedom Foundation]] said they had received over 200 complaints from over 50 different US military installations with comments like, &quot;President Trump has been anointed by Jesus to light the signal fire in Iran to cause Armageddon and mark his return to Earth&quot;, per an email from one [[w:Non-commissioned officer|NCO]].&lt;ref&gt;Nick Mordowanec (2026).&lt;/ref&gt; With Hegseth holding monthly Christian worship services in the Pentagon during business hours,&lt;ref&gt;Black (2025), Mayes-Osterman (2025). See also the section on &quot;[[w:Pete Hegseth#Pentagon Christian worship services and &quot;biblically sanctioned war&quot;|Pentagon Christian worship services and &quot;biblically sanctioned war&quot;]] in the Wikipedia article on [[w:Pete Hegseth|Pete Hegseth]], accessed 2026-05-14.&lt;/ref&gt; this suggests that Hegseth could have appointed enough Christian nationalists to key positions to initiate nuclear attacks on Iran or Russia, claiming that President Trump had ordered such whether he had or not.&lt;ref&gt;The [[w:Gold Codes|Gold Codes]] carried in the &quot;[[w:nuclear football|nuclear football]]&quot; required by the [[w:Permissive action link|permissive action link]]s would ''not'' prevent Hegseth and a few others appointed by him from initiating nuclear Armageddon, according to Ellsberg, who had been a nuclear war planner for presidents Eisenhower, Kennedy, Johnson, and Nixon, before releasing the ''[[w:Pentagon Papers|Pentagon Papers]]''. Ellsberg (2017, p. 69) insisted that the security provided by those Gold Codes were a hoax, because otherwise a single nuclear detonation on Washington, DC, when both the president and vice president were in town &quot;would would definitively block any authorized, coordinated nuclear response to that or any subsequent nuclear attack.&quot;&lt;/ref&gt; 

The biggest risk today may be the risk of [[w:Nuclear holocaust|nuclear Armageddon]], which seems on average to grow over time consistent with experience with &quot;[[w:system accidents|system accidents]]&quot; in other fields: It is naive to assume that any system as complex as military command, control and communications systems never fail. And managers of complex systems subject to rare, catastrophic failures &quot;learn&quot; from experience that they can take ever greater risks, because they have &quot;safely&quot; done so in the past — until there is a catastrophe:&lt;ref&gt;Kahneman and Klein (2009) found that expert intuition, when it exists, is learned from frequent, rapid, high quality feedback. With anything nuclear, mishaps are so rare that managers develop &quot;expert intuition&quot; that they can &quot;safely&quot; ignore safety concerns -- until there is a catastrophe. See also Sagan (1993).&lt;/ref&gt; 

Veterans for Peace (2022) recommend global reduction and rapid elimination of nuclear weapons &quot;to reduce the real risk of nuclear confrontation through accidental launch or miscalculated escalation&quot;. 

==== National security tariffs ====

Free trade agreements supported by the [[w:World Trade Organization|World Trade Organization]] allow exemptions for national security and other objectives. [[Responding to a nuclear attack|Even a minor nuclear war between India and Pakistan would have a negative impact on the entirety of humanity]]. It might therefore be sensible for parties to the [[w:Treaty on the Prohibition of Nuclear Weapons|Treaty on the Prohibition of Nuclear Weapons]] (TPNW) to institute gradually increasing tariffs on nuclear weapon states, not so great as to seriously impact the economy of the nation applying such tariffs but aggressive enough to gradually wean their economy from reliance on trade with nuclear-weapon states that refuse to support the TPNW. 

See also the chapter below on [[/Media Literacy and You/Responding to a nuclear attack/|Responding to a nuclear attack]]. 

===Research on the effectiveness of deterrence and implications=== 

Lebow and others have provided substantial documentation of case studies claiming that leaders are often not rational, and deterrence based on threatening use of military force beyond one’s own borders has been ''as likely to provoke as prevent'' undesired behavior.&lt;ref&gt;Lebow (2025, 2024), Lebow et al. (2023).&lt;/ref&gt; The most obvious portions of this threat can be entirely eliminated by policies clearly and effectively forbidding use of force beyond one’s own borders. This can be signaled in at least three ways: 

* Eliminate all weapon systems like missiles and aircraft with a range of more than, e.g., a hundred miles or 200 kilometers with the possible exception of surveillance only aircraft that cannot be easily configured to carry [[w:Materiel#Military|ordnance]], e.g., explosives. Similarly eliminate nuclear weapons, which few if any countries would want to use for military defense inside their own borders. 

* Supply a national guard and reserves with weapons, training, and rules of engagement that prohibit projecting force beyond one’s own borders. Train them also in development and use of improvised explosive devices and other tactics and devices like low cost military drones. 

:Afghanistan is said to be the &quot;[[w:Graveyard of empires|Graveyard of empires]]&quot;. They defeated the British three times (1839–1842, 1878–1880, 1919), the Soviet Union (1979–1989), and the US (2001–2021). Each victory came with foreign supplies, but any foreign troops helping Afghanis were primarily under the command of local leaders. 
:The [[w:2003 invasion of Iraq|2003 invasion of Iraq]] might have produced [[w:Nation-building|nation-building]] more like the experience of [[w:Nation-building#Germany and Japan after World War II|Germany and Japan after World War II]] if the US had mandated a vigorous adversarial press instead of strict censorship, according to McChesney and Nichols.&lt;ref&gt;McChesney and Nichols (2010, Appendix II. Ike, MacArthur and the Forging of Free and Independent Press, pp. 241-254).&lt;/ref&gt; This claim by McChesney and Nichols was not endorsed by [[News from Germany 1900-1945 and implications for today#After the war in Germany vs. Iraq|University of British Columbia History professor Heidi Tworek]], who said the democratization efforts in Germany and Japan after World War II were more complicated than that implied by that brief discussion by McChesney and Nichols.&lt;ref&gt;The 2025-07-03 interview with Tworek is available at &quot;[[News from Germany 1900-1945 and implications for today]]&quot;, accessed 2026-05-14.&lt;/ref&gt; However, the research by Usher and Kim-Leffingwell (2022) and the related research on news deserts summarized in the preface to this ''[[Media Literacy and You]]'' book largely supports those claims by McChesney and Nichols.
:[[w:Defense industry of Ukraine|Ukraine has become a world leader in military drones]], many of which are dramatically cheaper than alternatives. Most of those have limited range but have been useful for reconnaissance and delivery of ordnance and improving targeting of, e.g., surface to air missiles. 
:[[w:Eliot A. Cohen|Eliot Cohen]], who served as a special advisor to [[w:United States Secretary of State|US Secretary of State]] [[w:Condoleezza Rice|Condoleezza Rice]] from 2007 to 2009, wrote, &quot;As the United States discovered in Iraq and Afghanistan, no matter how large, technologically advanced, and proficient an army is, motivated insurgents can still inflict casualties in the tens of thousands.&quot;&lt;ref&gt;Cohen (2022), cited from Horton (2024, p. 1026).&lt;/ref&gt; Cohen recommended we &quot;Arm the Ukranians now&quot;. Horton said that the neoconservatives learned from Iraq War II and Afghanistan that the US &quot;should fight like those who defeated them.&quot;&lt;ref&gt;Horton (2024, p. 1026).&lt;/ref&gt; 
:Leading economist [[w:Jeffrey Sachs|Jeffrey Sachs]] addressed the European Parliament 2025-02-19, claiming that the tragedy that befell Serbia in 1999 and subsequent US uses of force in Iraq and Syria, plus wars in Africa including Syria, Somalia and Libya and the current wars in Ukraine and the Israel-Hamas war, &quot;are to a very significant extent the result of deeply misguided US policies.&quot;&lt;ref&gt;Sachs (2025-02).&lt;/ref&gt; He said that Europe should craft its own foreign and military policies, independent of the US. ''[[w:Le Monde Diplomatique|Le Monde Diplomatique]]'' noted that Sachs' speech has circulated among social media since ''but has yet to be seriously discussed by major European media.''&lt;ref&gt;Sachs (2025-04; emphasis added).&lt;/ref&gt; 

* Change the laws of government secrecy so government officials cannot secretly interfere in the internal affairs of foreign countries or otherwise project force outside their own borders. This might be achieved in the US in part by requiring anyone with information about questionable actions by government officials to provide such documentation to one or more congressional oversight bodies while also allowing any current or former government employee or contractor to file suit in any US federal jurisdiction if they feel they have been punished for refusing to support questionable activities. In addition, federal judges should be authorized to subpoena classified government documents that may be relevant to any case in their jurisdiction and declassify them subject to appellate review if they believe the national interest would be better served by declassification. 

:If the law is changed without a substantive [[#1. Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content.|citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference]], as discussed above, the change could be merely cosmetic and unconvincing to local public officials and potential adversaries. 
:Connelly (2023) noted that US government secrecy has in the past encouraged administration officials to do things to provoke actions by foreign entities that can then be denounced as “unprovoked” to stampede the US Congress and the public into supporting counterproductive uses of military force, as discussed above.&lt;ref&gt;See also Connelly et al. (2023).&lt;/ref&gt; A more diverse media culture should make it harder for administration officials to lie to the public and to Congress — and harder to punish government employees who tell their managers that they should not lie to Congress, as they reportedly did to [[#Richard Barlow and nuclear proliferation|Richard Barlow]], mentioned above. 
:The Barlow case and many others explain why the US should, e.g., give federal judges the authority to subpoena classified documents and declassify them if they believe the public good is better served from declassification than continued secrecy.&lt;ref&gt;See, e.g., the 2025-05-08 interview with Seth Stern and Lauren Harper discussing what the &quot;[[Freedom of the Press Foundation says...]]&quot;, Graves (2014), and [[w:Moynihan Commission on Government Secrecy|Moynihan Commission on Government Secrecy]], accessed 2026-05-06. Graves (2021) recommends &quot;Congressional Gold Medals for&quot; Barlow and whistleblowers.&lt;/ref&gt; 

These policies would make it hard for any foreign leader to justify an attack for multiple reasons: First, it would be difficult to convince their supporters that such an attack is necessary. Second, a rational foreign leader might be hesitant to invade a country that is prepared to fight a guerrilla war. Germany reportedly considered invading [[w:Switzerland during World War I and World War II|Switzerland during both World Wars I and II]] and decided against it in part because Switzerland had large, well-trained ready reserves, who were ready to fight. Belgium seemed to be an easier route.&lt;ref&gt;Documented in Wikipedia, &quot;[[w:Switzerland during World War I and World War II|Switzerland during World War I and World War II]]&quot;, accessed 2026-05-06. Switzerland also has many mountains, which make it easier to defend, but the capabilities of the Swiss military also influenced the German decision to avoid Switzerland.&lt;/ref&gt; Third, even if foreign invaders defeat the guerrillas, they should not assume that their invading forces would continue to follow orders. [[w:Rescue of the Danish Jews|Ninety-nine percent of Danish Jews reportedly survived World War II]] because of Danish noncooperation ''supported by a German diplomat''.&lt;ref&gt;Wikipedia, &quot;[[w:Rescue of the Danish Jews|Rescue of the Danish Jews]]&quot;, accessed 2026-05-06.&lt;/ref&gt; 

With policies like these in place, it would be hard for foreign leaders to convince their supporters of a need to attack, as [[w:2022 Russian invasion of Ukraine|Putin did when invading Ukraine in 2022]],&lt;ref&gt;The Wikipedia article on &quot;[[w:2022 Russian invasion of Ukraine|2022 Russian invasion of Ukraine]]&quot;, accessed 2026-05-06, includes a paragraph saying, 'In July 2021, Putin published an essay &quot;On the Historical Unity of Russians and Ukrainians&quot;, in which he called Ukraine &quot;historically Russian lands&quot; and claimed there is &quot;no historical basis&quot; for the &quot;idea of Ukrainian people as a nation separate from the Russians&quot;'. Putin was accused of promoting Russian imperialism, historical revisionism and disinformation. Writing in 2024, Michael McFaul and Robert Person described this essay as representing not only &quot;cynical propaganda&quot; but also Putin's &quot;deeply held and internalized beliefs&quot;. See the Wikipedia article for references supporting those claims.&lt;/ref&gt; as [[w:2025 India–Pakistan crisis|India did when attacking Pakistan in 2025]], and as [[w:Invasion of Poland|Hitler did when invading Poland in 1939]], to name only three examples. 

=== If we continue to base deterrence on threats === 

There are now calls for Europe to get their own nuclear weapons,&lt;ref&gt;Burgard (2025).&lt;/ref&gt; while Iran, Saudi Arabia, Turkey, South Korea and Taiwan have been suggested as other candidates for acquiring nuclear weapons should they feel a sufficient need.&lt;ref&gt;Ruehl (2024).&lt;/ref&gt; 

It is difficult to imagine how the number of nuclear weapon states could be increased without increasing the risks of a nuclear war, consistent with the discussion of &quot;[[w:system accident|system accident]]s&quot; earlier in this chapter.

Secondarily, intelligence services with information on political corruption including attempts to intimidate and murder journalists should not be allowed to keep that information secret: They should be required to find ways to leak that information to journalists. Such attacks on journalists in their own country should be exposed and prosecuted if the evidence seems likely to obtain a conviction. Intelligence services with information about such attacks in other countries should be required to find ways to leak it to competent journalists without identifying their sources and methods: Doing so would likely reduce political corruption worldwide and with that the risks of war. 

== Collateral damage ==

The research cited above supports the claim that, 

:''[[w:Collateral damage|Collateral damage]] that our designated enemies commit prove to us that they are subhuman or criminally misled.''
:''Meanwhile, collateral damage that we commit is unfortunate but necessary -- from our perspective. However, it proves to our designated enemies that we are subhuman or criminally misled.'' 

This observation supports this entire program of deterrence without threat: 
* Forbidding use of force beyond one’s own borders and covert interference in foreign countries would automatically reduce collateral damage. It would also avoid uses of force that seem not to contribute to broadly shared peace and prosperity, according to research cited above. 
* The effectiveness of nonviolent noncooperation rests in part on its near universal avoidance of collateral damage. 
* Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content should make it much harder for major media to convince the public to do things contrary to their best interests, like invading or interfering covertly in foreign countries.

There are plenty of contrary claims in the major media, but the lead author of this chapter is not aware of any that are based on serious research. 

In the absence of such research, the current author finds it difficult to imagine any national defense policies that carry a greater risk of nuclear Armageddon than our current policies, as discussed in the next chapter of this book on ''[[Media Literacy and You]]'' on &quot;[[Media Literacy and You/Responding to a nuclear attack|Responding to a nuclear attack]]&quot;. That chapter, in sum, claims that the ''worst'' response to a nuclear attack would be nuclear response, because it would escalate a catastrophe killing millions of humans to one killing ''billions'', possibly 80 percent of humanity in a war between the US and Russia that lofts so much smoke from burning cities to the stratosphere where it covers the globe depressing crop yields for years during with 99 percent of the humans in the US, Europe and Russia would starve to death if they did not die of something else sooner. Moreover, the record of &quot;[[w:System accident|system accident]]s&quot; suggests that the chances of such a war before the end of this century is substantially greater than the 40 percent median estimate based on history mentioned in a presentation on &quot;[[Time to nuclear Armageddon]]&quot; delivered to the 2019 Joint Statistical Meetings. 

This chapter is being written in the hopes of inspiring action to improve the prospects for broadly shared peace and prosperity for the long term. 

== Exercises ==

1. Disconfirmation bias: Brainstorm your biggest concerns about a current or possible future war. 
:1.1. Select the one that is of greatest concern to you currently. 
::One issue that may not be a major concern for many but might elicit a broad consensus for action would be a campaign to ask elected officials in the US Congress to explain how we benefit from the provisions of the USA Patriot Act of 2001 that authorize [[#life in prison for teaching nonviolence|life in prison for teaching nonviolence]]. 
:1.2. Who are your designated enemies? 
:1.3. Research what your designated enemies are saying about your biggest concern.  
:1.4. Under what circumstances would you support what you see your designated enemies advocating or doing? 
::If you cannot see such circumstances, expand your research: Look for more sources that support your designated enemies. 

2. Interacting: Ask others if you can share what you've learned about that conflict. If they say, &quot;No&quot;, don't push it. If they agree, share what you've learned in a friendly supportive manner without saying that anything is &quot;true&quot;. 

::''Show me someone who knows the truth, and I will show you someone who is dangerous.''

:2.1. The primary goal in this is ''not'' to convince anyone that you are right and they are wrong but to lower the level of anger and increase the level of tolerance for dissenting views. 
:2.2. Another goal is to comfortably enjoy civil conversations of this nature, agreeing to disagree agreeably and building trusting relationships that support collaboration on issues of common concern. 
:2.3. After becoming adept at building collaborations on issues of common concern, you might consider teaching this important skill and approach to issues.  

3. Teaching: Each one teach two, as discussed in the section on &quot;[[Media Literacy and You#Text and self-help book and point of discuss|Text and self-help book and point of discuss]]&quot; in the preface to this book.

:''Humanity is one misunderstanding, one miscalculation away from nuclear annihilation. ... This is madness. We must reverse course.''
:  -- [[w:António Guterres|UN Secretary General António Guterres]]  (2022)&lt;ref&gt;Jacobsen (2024), BBC (2022).&lt;/ref&gt;

:This book is a combination instruction manual on [[w:Media literacy|media literacy]] and an invitation to you to support collaborative / crowd-sourced research on how to improve the world's understanding of media literacy and how to accelerate its understanding and use globally for the betterment of humanity. 

Part I of this book on ''[[Media Literacy and You]]'' discusses &quot;The media and political economy&quot;. Except in times of terror, massive lawlessness or war, most humans place a high priority on their financial situation, the primary focus of Part I. Part II on &quot;The media and war&quot; focuses on security concerns starting with this chapter on &quot;Deterrence without threat&quot;. 

== Introduction ==

Every individual and group has a right and an obligation to defend itself. Unfortunately, when most humans&lt;ref&gt;We distinguish here between &quot;humans&quot; and &quot;people&quot; or &quot;persons&quot;, because under current US law, corporations are &quot;people&quot; and money is speech, per the US Supreme Court decision in ''[[w:Citizens United v. FEC|Citizens United v. FEC]]'' (2010) and many other judicial rulings and US law such as the [[w:Patriot Act|Patriot Act]] of 2001.&lt;/ref&gt; think of defense, they often think of violent responses to provocations. 

However, there is a growing body of research documenting 

:(a) how most uses of violence are counterproductive, and 
:(b) there are usually nonviolent options to violence that would more effectively promote broadly shared peace and prosperity for the long term. 

This research is rarely discussed by major media outlets, because it would offend the &quot;people&quot;&lt;ref&gt;We put &quot;people&quot; in quotes in this essay, because that term includes corporations under current US law.&lt;/ref&gt; who control most of the money for the media: Nonviolence threatens their ability to get compliance from security forces. As a result, many elites prefer to use force to the detriment of the bottom 99 percent of humanity. As discussed below, a military posture that supports projecting force beyond one’s own borders may be as likely to ''provoke'' as ''prevent'' an attack.&lt;ref&gt;For example, Lebow (2025) cites some of his previous work with others to support the claim that large militaries have been &quot;more provocative than preventative in&quot; their effects. And Lebow (2024) insists that, &quot;Policymakers respond more instinctively than analytically in deciding that some policy is or is not in the national interest.&quot; See also Lebow et al. (2023).&lt;/ref&gt; 

This chapter outlines a 3-part strategy that research suggests would more likely lead to better outcomes for the vast majority of humans: 

# Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content. 
# Training in nonviolent noncooperation for anyone willing to listen. 
# Forbid uses of force beyond one’s own borders and covert interference in foreign countries. 

We now discuss each of these briefly. 

== 1. Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content. == 

It seems that

:''Primary drivers of every major conflict include differences between the media that the different parties find crecible.''

In a recent interview with [[w:Fordham University|Fordham University]] Professor Emerita of Communications Robin Andersen,&lt;ref name=Andersen&gt;&lt;!--Robin Andersen--&gt;{{cite Q|Q132982358}}&lt;/ref&gt; she agreed with this claim and added: 

:''We only have enemies of our very own making.''

The media are involved in this, because:  

:''The major media create the stage upon which politicians read their lines.''&lt;ref&gt;In 1791 James Madison, who represented part of Virginia in the US House of Representatives 1789-1801 and later became the 4th President of the US (1809-1819), said, &quot;Public opinion sets bounds to every government, and is the real sovereign in every free one.&quot; Quoted from the ''[[w:National Gazette|National Gazette]]'' (published 1791-1793) by Schmeller (2009, p. 36) and Sauer (2016, p. 5). Sauer described how the American Revolutionaries, especially the first four US presidents, planted stories in newspapers to build support for how they dealt with the [[w:Barbary corsairs|Barbary pirates]], who were seizing merchant ships, raiding European coastal towns and villages, and selling European captives into slavery. The first two US presidents, [[w:George Washington|Washington]] and [[w:John Adams|Adams]], used that support for protecting US shipping and citizens by paying tribute to government leaders in Morocco, Algeria, Tunisia, and Libya. The next two presidents, [[w:Thomas Jefferson|Jefferson]] and [[w:James Madison|Madison]], convinced Congress to fund a navy and marines to fight the [[w:Barbary Wars|Barbary Wars]]. This included the [[w:Battle of Derna (1805)|Battle of Derna]]  (April-May 1805), memorialized in the [[w:Marines' Hymn|Marines' Hymn]], which mentions actions &quot;to the shores of Tripoli&quot;. Sauer described how the policies were sold to the public via planted stories in the different partisan newspapers.&lt;/ref&gt; 

This works because (a) virtually everyone thinks they know more than they do ([[w:Overconfidence effect|overconfidence effect]]), and (b) virtually everyone prefers information and sources consistent with preconceptions ([[w:confirmation bias|confirmation bias]]). 

Also, in many, perhaps all, countries, the primary constituency for foreign and military policy is the people with foreign business interests. Many of these people also control substantial portions of the money for the media, which have too often encourage questionable and counterproductive uses of military force.&lt;ref&gt;If we [[w:follow the money|follow the money]], we might find that &quot;watchdogs generally protect the people who feed them&quot;, as discussed in the 2025-09-25 interview with British journalist and media reform activist Dan Hind discussing how the British [[Media Reform Coalition challenges anti-democratic media bias in the UK]].&lt;/ref&gt; 

=== Examples === 

A leader in documenting the role of the media in armed conflict is Robin Andersen,&lt;ref&gt;e.g., Andersen (2006, 2026).&lt;/ref&gt; but she is not alone. For example, [[w:University of Denver|University of Denver]] journalism professor Kareem El Damanhoury&lt;ref name=Daman&gt;&lt;!--Kareem El Damanhoury--&gt;{{cite Q|Q113752441}}&lt;/ref&gt; has compared how [[w:Gaza Strip|Gaza]] has been framed differently by [[w:Al Jazeera Media Network|Al Jazeera]], the [[w:BBC|BBC]]&lt;ref&gt;El Damanhoury et al. (2025).&lt;/ref&gt; and [[w:Fox News|Fox]].&lt;ref&gt;El Damanhoury and Saleh (2024).&lt;/ref&gt;&lt;ref&gt;Some of El Damanhoury's work in this regard [[Differences between media outlets including coverage of Gaza|is reviewed in a 2025-11-20 interview with him]].&lt;/ref&gt; 

==== World War I ====

Andersen's (2006) ''A Century of Media, A Century of War'' begins with a discussion of &quot;The birth of war propaganda&quot; in &quot;The Great War and the Fight between Good and Evil&quot;.&lt;ref&gt;Andersen (2006, ch. 1)&lt;/ref&gt; 

A more detailed but compatible discussion of the media and [[w:World War I|World War I]] is given by [[w:John Maxwell Hamilton|John Maxwell Hamilton]]. Among other things, he said: {{quote|

The first iron law of propaganda is that only the enemy does it.&lt;ref&gt;Hamilton (2020, p. 642). See also the [[John Maxwell Hamilton on American propaganda|2025-12-11 interview with Hamilton]].&lt;/ref&gt;}} 

[[File:MB Walker - German bayoneting children - Life - July 25, 1915.png|thumb|left|Figure 1. Stories of German soldiers impaling children on their bayonets were widely reported during the war. However, no credible evidence was found to support these claims when questions were raised after the war.&lt;ref&gt;{{cite web|title=Alleged German atrocities: Bryce report|url=http://www.nationalarchives.gov.uk/pathways/firstworldwar/spotlights/p_alleged_german.htm|publisher=The National Archives|access-date=13 July 2014}}&lt;/ref&gt;]]

Andersen (2006, pp. 8-9) said, {{quote|

James Bryce, the former British ambassador to the United States, ... helped prepare a sixty-one page ''Report on the Committee on alleged German Outrages'', which was translated into thirty languages and was said to be based on twelve hundred depositions ... included gruesome and titillating details of how German soldiers publicly raped Belgian girls in the marketplace at Liege and bayonetted a two-year-old child. ... [A]fter the war a Belgian commission of inquiry found no evidence for any major accusation in the report. ...}}
{{quote|
German propagandists, on the other hand, ... &quot;bungled, because they were naïve: they thought the success of the war depended almost solely on military strategy and therefore they tended to neglect propaganda.&quot; ... Thus, when German soldiers shot some Allied nurses who had carried weapons, they admitted it openly. The Allies reported the incident as an atrocity and featured it in press propaganda. When French troops shot German nurses under similar circumstances, the Germans failed to exploit it.}} 

==== Jonathan Swift 1710 ====

This is not limited to World War I. In 1710, [[w:Jonathan Swift|Jonathan Swift]] reportedly said, &quot;Falsehood flies, and truth comes limping after ... like a physician, who hath found out an infallible medicine, after the patient is dead.&quot;&lt;ref name=Swift&gt;Excerpted from a line in [[Wikiquote:Jonathan Swift]] consulted 2026-04-13.&lt;/ref&gt;  

==== The Marines' Hymn ====

The [[w:Marines' Hymn|Marine Corps Hymn]] begins, {{quote|

From the Halls of Montezuma

To the shores of Tripoli;

We fight our country's battles

In the air, on land, and sea.}}

The &quot;[[w:Battle of Chapultepec|Halls of Montezuma]]&quot; refer to the [[w:Mexican–American War|Mexican–American War]], which was fought to expand slavery first into [[w:Texas|Texas]]  -- and supporters of slavery hoped that would help expand slavery further west. The &quot;[[w:Battle of Derna (1805)|shores of Tripoli]]&quot; were part of the [[w:Barbary Wars|Barbary Wars]], which were fought to reduce the need to pay (a) tribute to the [[w:Barbary Coast|Barbary or Berber]] states of [[w:Morocco|Morocco]], [[w:Algeria|Algeria]], [[w:Tunisia|Tunisia]], and [[w:Libya|Libya]] or (b) ransom to [[w:Barbary corsairs|Barbary pirates]], who were otherwise capturing Christians and selling them into slavery. 

Did the bottom 99 percent of the US population of that time benefit? Or did these wars (and any tribute and ransom paid by the US government before the Barbary wars) constitute a hidden transfer of wealth from the poor to the wealthy? 

A partial answer to this question is that [[w:tariff|tariff]]s on imported goods covered between 80 and 95 percent of all federal revenue up to 1860, and [[w:excise|excise taxes]] on only a few goods, such as whiskey, rum, tobacco, snuff and refined sugar, made up nearly all the rest.&lt;ref&gt;See the section on &quot;[[w:Excise tax in the United States#Historical background|Historical background]]&quot; in the Wikipedia article on &quot;[[w:Excise tax in the United States|Excise tax in the United States]]&quot;, accessed 2026-05-26.&lt;/ref&gt; The money raised from taxes on income during the Civil War, visible in Figure 3 above, were apparently negligible as a portion of federal revenue during the Barbary Wars and the Mexican-American War.  

==== Gulf of Tonkin Resolution: &quot;Betray the nation or do not get elected.&quot; ====

Regarding the [[w:Vietnam War|Vietnam War]], former president [[w:Dwight D. Eisenhower|Eisenhower]] wrote in his autobiography, which appeared in 1963 (he left the presidency 1961-01-20), that he had never communicated {{quote|

with a person knowledgeable in Indochinese affairs [including Vietnam] who did not agree that had elections been held as of the time of the fighting [leading to the defeat of the French in 1954], possibly 80 per cent of the population would have voted for the Communist [[w:Ho Chi Minh|Ho Chi Minh]].&lt;ref&gt;Eisenhower (1963, p. 372).&lt;/ref&gt;}}

[[w:Joseph McCarthy|Joseph McCarthy]], who had been elected to the US Senate in 1946 and &quot;experienced a meteoric rise in national profile beginning on February 9, 1950, when he gave a&quot; speech during which he said something like, &quot;The [[w:United States Secretary of State|State Department]] is infested with communists. I have here in my hand a list of 205—a list of names that were made known to the Secretary of State as being members of the Communist Party and who nevertheless are still working and shaping policy in the State Department.&quot; McCarthy's mostly baseless claims went largely unchallenged in the media, including accusing the Democrats of &quot;twenty years of treason&quot; for having been allied with the Soviet Union, which took the bulk of casualties during World War II. 

By the end of 1953 with (Republican) Eisenhower as president roughly 11 months, McCarthy was complaining about &quot;''21'' years of treason&quot;, complaining that Eisenhower was not sufficiently aggressive in rooting out the communists who McCarthy claimed were in the government.&lt;ref&gt;Fried (1997, p. 179).&lt;/ref&gt; 

Then the French were defeated by Vietnamese communists 1954-05-07 in the [[w:Battle of Dien Bien Phu|Battle of Dien Bien Phu]]. The [[w:1954 Geneva Conference|1954 Geneva Conference]], which had begun eleven days earlier, 1954-04-26, concluded 1954-07-21 with the &quot;Geneva Accords of 1954&quot;.&lt;ref&gt;The [[w:Battle of Dien Bien Phu|Battle of Dien Bien Phu]], 1954-05-07, effectively ended the [[w:First Indochina War|French Indochina War]]. This led to the [[w:1954 Geneva Conference|Geneva accords of 1954]], officially dated 1954-07-20 but actually signed the following morning. Those accords took effect on three different dates, July 27 and August 1 and 11 in three different sectors of Vietnam. See &lt;!--Agreement on the Cessation of Hostilities in Vietnam--&gt;{{cite Q|Q139676410}}&lt;/ref&gt; Those accords called for UN-supervised elections for July of 1956, when Eisenhower would presumably be campaigning for reelection. Eisenhower doubtless knew that he might lose his bid for re-election in 1956, if the Communist Ho Chi Minh won elections in July of that year. 

:''The consistent suppression of honest portrayal in the major media of that day of the perspective of anyone whom Eisenhower considered &quot;knowledgeable in Indochinese affairs&quot; gave him -- and his successors [[w:John F. Kennedy|Kennedy]], [[w:Lyndon B. Johnson|Johnson]], and [[w:Richard Nixon|Nixon]] -- the choice between betraying the nation or not getting elected.'' 

In this environment, the [[w:Operation 34A|US initiated a series of clandestine operations against North Vietnam]] including infiltrating CIA-recruited spies and supporting attacks against North Vietnam by South Vietnamese commandos.&lt;ref&gt;Paterson (2008).&lt;/ref&gt; This included a raid 1964-07-30 by South Vietnamese commandos on the island of Hòn Mê, roughly 300 km (180 miles) north of the [[w:Vietnamese Demilitarized Zone|Vietnamese Demilitarized Zone]] in the [[w:Gulf of Tonkin|Gulf of Tonkin]], covered by [[w:DESOTO patrol|US naval vessels]] patrolling in that area. Then during a dark and stormy night six days later, US naval vessels opened fire on radar snow, and President Johnson requested and received Congressional approval of the [[w:Gulf of Tonkin Resolution|Gulf of Tonkin Resolution]]; then-[[w:United States Secretary of Defense|US Secretary of Defense]] [[w:Robert McNamara|McNamara]] claimed those attacks were &quot;unprovoked&quot;.&lt;ref&gt;Karnow (1983, p. 375). See also the section on [[w:Gulf of Tonkin Resolution#Congress votes|Congress votes]]&quot; in the Wikipedia article on [[w:Gulf of Tonkin Resolution|Gulf of Tonkin Resolution]], accessed 2026-05-14.&lt;/ref&gt;

In this media environment, only two officials in the US Congress voted against the Gulf of Tonkin Resolution: [[w:Ernest Gruening|Ernest Gruening]] (D-AK) and [[w:Wayne Morse|Wayne Morse]] (D-OR). Gruening lost in his next primary campaign to [[w:Mike Gravel|Mike Gravel]], and Morse lost in his next general election campaign to [[w:Bob Packwood|Bob Packwood]]. These results support the previous claim that the major media give politicians the choice: 

:''Betray the nation, or do not get elected.''

That resolution became the primary authorization for the US war in Vietnam until Congress ended the funding. 

==== Was the Vietnam War lost in Washington or by media biases? ====

[[w:John Mueller|John Mueller]], prolific author, Professor Emeritus of international relations at [[w:Ohio State University|Ohio State University]] and Senior Fellow at the [[w:Cato Institute|Cato Institute]], said that the most effective thing the US did to win the [[w:Cold War|Cold War]] was —

:''nothing'': 

Between the [[w:Fall of Saigon|Fall of Saigon]] in 1975 and the inauguration of [[w:Ronald Reagan|Ronald Reagan]] as President of the US, the US &quot;went into a sort of containment funk: it effectively adopted a policy of complacency (or perhaps of appeasement) as it watched from the sidelines as the Soviet Union … opportunistically gathered a set of Third World countries into its imperial embrace: Angola in 1976, Mozambique and Ethiopia in 1977, South Yemen and Afghanistan in 1978, Grenada and Nicaragua in 1979.&quot;&lt;ref&gt;Mueller (2021,  p. 59).&lt;/ref&gt; Nearly all became major economic and political drains on the Soviets with Afghanistan being the worst. And their Warsaw Pact allies in Eastern Europe became a severe economic drain and psychic problem.&lt;ref&gt;Mueller and Graves (2023).&lt;/ref&gt; 

President Reagan, inaugurated 1981-01-20, had a very different vision of the role of the US in foreign relations from his predecessor, [[w:Jimmy Carter|Jimmy Carter]]. In 1983-06-21 Reagan insisted, &quot;We cannot permit the Soviet-Cuban-Nicaraguan axis to take over Central America&quot;, because the consequences would include &quot;a tidal wave of refugees ... 'feet people' ... swarming into our country.&quot;&lt;ref&gt;Clines (1983).&lt;/ref&gt; 

Other sources&lt;ref&gt;e.g., Andersen (2006, Part II).&lt;/ref&gt; insist the opposite, that the vast majority of deaths in Central America during the Reagan years were poor humans petitioning nonviolently for a redress of grievances, suppressed by terrorist / death squads supported by the Reagan administration largely in violation of laws passed by Congress and signed by President Reagan. On 1986-10-05 [[w:Corporate Air Services HPF821|a Nicaraguan soldier with a surface to air missile shot down a C-123]] cargo aircraft carrying supplies to the Contra roughly 35 miles (56 km) north of Costa Rica. Documents found in the wreckage and a confession by the sole survivor led to the [[w:Iran–Contra affair|Iran-Contra hearings]] the following year, during which Lt. Col. [[w:Oliver North|Oliver North]] insisted, &quot;We didn't lose the war in Vietnam ..., we lost it in this city.&quot;&lt;ref&gt;Andersen (2006, p. 137). See also, Wikipedia, &quot;[[w:Stab-in-the-back myth|Stab-in-the-back myth]]&quot;, accessed 2026-05-13.&lt;/ref&gt; 

The previous section on the &quot;Gulf of Tonkin Resolution&quot; provides an alternative narrative of the Vietnam War: If as Eisenhower claimed, &quot;possibly 80 per cent of the [Vietnamese] population would have voted for the Communist [[w:Ho Chi Minh|Ho Chi Minh]]&quot; if elections had been held there, it's hard to imagine how anyone else could have won without aggressive action that actually ''improved'' the lives of Vietnamese peasants in the South. US-led efforts there were officially designed to win &quot;[[w:Hearts and Minds (Vietnam War)|Hearts and Minds]]&quot; but were implemented with such coercion that the result was the opposite. A cynic might say that it is hard to win people's hearts and minds by killing them. 

====Richard Barlow and nuclear proliferation====

There is also documentation that the US helped Pakistan get nuclear weapons and destroyed the career of an intelligence analyst, [[w:Richard Barlow (intelligence analyst)|Richard Barlow]], for telling his managers they should not lie to Congress about it. Barlow has insisted that neither Pakistan nor North Korea would have nuclear weapons and Iran would not have a nuclear weapons program today, if the US had followed its own laws. Barlow’s claims, including his punishment by administration officials, have been reported in major media outlets&lt;ref&gt;e.g., Stein (2013). See also Wikipedia, &quot;[[w:Richard Barlow (intelligence analyst)|Richard Barlow (intelligence analyst)]]&quot;, accessed 2026-05-06.&lt;/ref&gt; but not in a way that would seriously limit the ability — and need — for administration officials to lie to Congress. 

If Barlow's claims are accurate, it suggests that US government officials violated US obligations under the [[w:Treaty on the Non-Proliferation of Nuclear Weapons|Non-Proliferation Treaty]] (NPT).&lt;ref&gt;Per the [[w:Treaty Clause|Treaty Clause]] of the US Constitution, a treaty negotiated by the President and approved by the Senate has &quot;the force of federal law.&quot;&lt;/ref&gt; 

==== Nayirah testimony and the 1990-1991 Gulf War ====

A more recent example is the 1990-10-10 testimony by [[w:Nayirah testimony|Nayirah al-Ṣabaḥ to the US Congressional Human Rights Caucus]], two months after the Iraqi invasion of Kuwait. She claimed to have seen Iraqi soldiers taking premature babies out of incubators in a maternity ward before looting the incubators and leaving the babies to die on the floor after the Iraqi invasion of Kuwait; she said she had been a volunteer nurse in the hospital at that time. 

The failure of journalists, including with the ''[[w:NBC Nightly News|NBC Nightly News]]'', to adequate check facts behind this and other atrocity stories helped convince the US public to support the US-led invasion of Iraq in 1990-1991. Nayirah's statements were widely publicized and cited numerous times in the United States Senate and by American president George H. W. Bush to contribute to the rationale for pursuing military action against Iraq. It was later revealed that she was the daughter of Kuwaiti ambassador to the US, [[w:Saud Nasser Al-Saud Al-Sabah|Saud Nasser Al-Saud Al-Sabah]], &quot;Reps. [[w:Tom Lantos|Tom Lantos]] and [[w:John Porter (Illinois politician)|John Edward Porter]], who sponsored the congressional hearings, had started a group called the Congressional Human Rights Foundation that had received $50,000 from Citizens for a Free Kuwait, as well as free office space in [[w:Hill &amp; Knowlton|Hill and Knowlton]]'s Washington headquarters&quot;,&lt;ref&gt;Rowse (1992).&lt;/ref&gt; and the public relations firm Hill and Knowlton had made a video while coaching her rehearsing her perjury and used that to prepare a video press release &quot;that eventually reached a total audience of about thirty-five million&quot;, 14 percent of the [[w:Demographic history of the United States|US population of 249 million per the census then in process]], with portions aired on the ''[[w:NBC Nightly News|NBC Nightly News]]'' the night after the testimony.&lt;ref&gt;Andersen (2006, pp. 170-171).&lt;/ref&gt; 

==== 1998 Embassy bombings and September 11 ====

As another example, there is substantial documentation available today that [[1998 Embassy bombings and September 11|the suicide mass murders of September 11, 2001]], likely would not have occurred if the US had treated the 1998 bombings of the US embassies in Kenya and Tanzania as law enforcement issues. Muslim clerics all over the world initially condemned those acts. Al-Qaeda was dead. Their funding had largely dried up. And bin Laden was scheduled to be extradited the following month to Saudi Arabia to be prosecuted for treason, where he would likely have been convicted and executed. Mayer (2008, p. 114) claimed those embassy bombings were motivated as retaliation for US support for torture.&lt;ref&gt;For more on torture, see the the section on [[#Make media responsible for harms|Make media responsible for harms]] below.&lt;/ref&gt; 

But it seemed questionable at best whether major media executives in the US would have given favorable coverage to such a diplomatic solution. Instead, the US bombed a pharmaceutical plant in Sudan and al-Qaeda training camps in Afghanistan. Then Muslim public opinion turned 180 degrees to conclude, &quot;Bin Laden is right: The US ''is'' an evil empire.&quot; The US became bin Laden’s only indispensable ally, according to the CIA agent responsible for tracking bin Laden at that time.&lt;ref&gt;Scheuer (2004, p. xv).&lt;/ref&gt; Leading Saudis started supporting al-Qaeda, including some working for the Saudi embassy and consulates in the US. Only one country seems to have been involved in the preparations for the September 11 attacks, and that was Saudi Arabia. But Saudis were friends of the Bush family, and a crisis is a terrible thing to waste.&lt;ref&gt;Romer (2009).&lt;/ref&gt; 

:''Did the US invade Afghanistan and Iraq on grounds that senior journalists and leading media executives should have known at the time were questionable and likely fraudulent — to the detriment of nearly everyone except the &quot;people&quot; who control most of the money for the media?'' 
:In particular, was Iraqi president [[w:Saddam Hussein|Saddam Hussein]] really a bigger threat to the US after he invaded Kuwait in 1990 or after the [[w:September 11 attacks|suicide mass murders of September 11, 2001]] than he was during the 1980s, when the US supported him [[w:Iran-Iraq War|killing Iranians]] or [[w:Anfal campaign|his own native Kurds]]? 

On 2003-05-29 [[w:BBC|BBC]] journalist [[w:Andrew Gilligan|Andrew Gilligan]] reported that the [[w:Tony Blaire|Blair government]] had &quot;sexed up&quot; [[w:September Dossier|intelligence reports]] issued the previous September to justify supporting the 2003-03-20 [[w:Iraq War|US-led invasion of Iraq]], two months before Gilligan's report. This led to the [[w:Hutton Inquiry|Hutton Inquiry]], which led to the resignations of Gilligan and the BBC's chairman and the firing of the BBC's director-general. However, the British public expressed so many reservations about the Hutton Inquiry that a follow-up investigation was ordered in 2009. This became the &quot;[[w:Iraq Inquiry|Iraq Inquiry]]&quot;, whose 2016-07-06 report essentially validated what Gilligan had said just over 13 years earlier. This provides one more example of the 1710 maxim of Jonathan Swift that, &quot;Falsehood flies, and truth comes limping after ... like a physician, who hath found out an infallible medicine, after the patient is dead.&quot;&lt;ref name=Swift/&gt;

====Ukraine war====

Page 1 of the 2023-05-04 edition of ''[[w:Le Monde Diplomatique|Le Monde Diplomatique]]'' carried a headline: 

:One year after the invasion of Ukraine: The media, vanguard of the war party,&lt;ref&gt;Halimi and Rimbert (2023) in the French-language original.&lt;/ref&gt;

consistent with Andersen (2006).

=== Make media responsible for harms ===

How might the world be different if injured parties could successfully sue major media for harms that result from government policies contradicted by evidence reasonably available to the major media outlets? 

For example, how might the world be different if: 

* combat veterans or their families could successfully sue major media outlets for biased reporting that stampede the nation into ill advised and counterproductive uses of military force on grounds that leading media personalities should have known at the time were questionable and likely fraudulent? 
* Vietnamese or Afghanis or Iraqis or Palestinians or victims in other countries could win similar lawsuits?
* immigrants could sue major media outlets for failing to publish reasonable summaries of the available research that says that immigrants on average are more entrepreneurial&lt;ref&gt;Aghion et al. (2022, pp. 266-270).&lt;/ref&gt; and no more likely to engage in criminal activities than native born, benefitting both the sending and receiving countries?&lt;ref&gt;The Wikipedia article on &quot;[[w:Immigration|Immigration]] cites research saying, &quot;that migration can be beneficial both to the receiving and sending countries. The academic literature provides mixed findings for the relationship between immigration and crime worldwide. ... [P]ublic perception often exaggerates the connection between immigration and crime, influenced by sensationalised media coverage and political rhetoric.&quot; The Wikipedia article on [[w:Immigration and crime|Immigration and crime]] notes that in some countries immigrants are over-represented in prison populations due to violations of immigration law or anti-immigrant biases in criminal justice. The Wikipedia article on &quot;[[w:Sanctuary city|Sanctuary city]]&quot; says that, &quot;Some studies on the relationship between sanctuary status and crime have found that sanctuary policies either have no effect on crime or that sanctuary cities have lower crime rates and stronger economies than comparable non-sanctuary cities.&quot; All references 2026-05-26.&lt;/ref&gt; 
* humans tortured by the US could sue the major media for suppressing honest discussion of the research that documents that torture is more likely counterproductive? An important report of the efficacy of torture was published in 1631 by [[w:Friedrich Spee|Friedrich Spee]], a German Jesuit priest and professor. A few years earlier, the Duke of Brunswick had invited Spee and another famous Jesuit scholar to supervise a continuation of the torture of a confessed witch. The Jesuits had previously told the Duke, &quot;The Inquisitors are doing their duty. They are arresting only people who have been implicated by the confession of other witches.&quot; The Duke then led the Jesuits to a woman being stretched on the rack and asked her, &quot;You are a confessed witch. I suspect these two men of being warlocks. What do you say? Another turn of the rack, executioners.&quot; &quot;No, no!&quot; screamed the woman. &quot;You are quite right. I have often seen .. . They can turn themselves into goats, wolves ... Several witches have had children by them. ... The children had heads like toads and legs like spiders.&quot;&lt;ref&gt;Pinker (2011, pp. 138-139). Mannix (1964, pp. 134-135). Mackay ( 2009, p. 320).&lt;/ref&gt; Crudely similar comments about the counterproductive nature of torture were made by Generals [[w:Stanley McChrystal|Stanley McChrystal]] (2013) and [[w:David Petraeus|David Petraeus]],&lt;ref&gt;DePaulo (2008).&lt;/ref&gt; who held command positions in Iraq and Afghanistan. The major media in the US has provided ample coverage of, e.g., comments by Donald Trump supporting torture (McCarthy 2016), while largely suppressing honest discussion of the research on it. 

Might the world be safer and more prosperous if major media outlets and their executives and journalists could be successfully sued when their biased reporting have substantive negative consequences? Might [[w:Freedom of information|the public's right to receive diverse information]] be advanced in this way, recognizing that false information disseminated by major media outlets can lead to substantive harms, similar to &quot;[[w:Shouting fire in a crowded theater|shouting ''fire'' in a crowded theater]]&quot;, while the same information disseminated by minor outlets would ''not'' produce such harms? 

Lawsuits of this nature could be facilitated by &quot;group libel&quot; laws. Activists were working to pass such laws in the 1940s. By 1950 those campaigns had been abandoned, according to Barbas (2023).&lt;ref&gt;See also Calvert et al. (2023, pp. 178ff).&lt;/ref&gt; 

[[w:Yael Eisenstat|Yaël Eisenstat]] agrees that under [[w:Section 230|Section 230]] of Title 47 of the US Code, &quot;No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider.&quot; However, Eisenstat insists that [[Online platforms' effects on public health, safety and democracy|&quot;an interactive computer service&quot; ''can'' be held liable when their algorithms have substantive negative consequences]], as in the jury verdicts against Meta in New Mexico&lt;ref&gt;Allyn (2026).&lt;/ref&gt; and against Meta and Google in Los Angeles.&lt;ref&gt;McQue (2026).&lt;/ref&gt; She said, &quot;those technologies, if they are, in the end, contributing to an illegal activity or to harm, that's what we should be addressing. ... The ultimate goal is not to shut down every social media company. The ultimate goal is to figure out what a safer online experience looks like and what accountability looks like when something unsafe happens.&quot; 

=== in sum ===

You, dear reader, can help overcome these problems by talking, as suggested in the exercises below and the rest of this book. If you can help others become less angry and more willing to agree to disagree agreeably with others, that should reduce the risk of war and improve the prospects for progress on other major problems facing humanity today. 

==2. Training in nonviolent noncooperation for anyone willing to listen == 

A major driver of the current conflict between India and Pakistan is mistreatment of Muslims in India. Simulations of a nuclear war between India and Pakistan suggest that such a war would likely produce a nuclear autumn lasting years during which 40 percent of humanity would starve to death if they did not die of something else sooner. Over 90 percent of those would be in countries not involved in the nuclear exchange.&lt;ref&gt;Xia et al. (2022). See also Wikiversity, &quot;[[Responding to a nuclear attack]]&quot;, accessed 2026-05-05.&lt;/ref&gt;

The recent &quot;[[w:2025 India–Pakistan conflict|2025 India–Pakistan conflict]]&quot; was a response by India to violence in Indian-administered [[w:Kashmir|Kashmir]] by terrorists allegedly supported by Pakistan. India would have had much more difficulty justifying violent repression of ''nonviolent'' protests, especially if a more diverse media ecology gave such protests more and more sympathetic coverage. 

During the [[w:Great Depression|Great Depression]], ethnic Germans in the [[w:Sudetenland|Sudetenland]] region of [[w:Czechoslovakia|Czechoslovakia]] were harder hit by increasing trade barriers than their non-German neighbors. They were therefore more open to populist and extremist movements such as fascism, communism and German irredentism.&lt;ref&gt;Wikipedia, &quot;[[w:Sudetenland|Sudetenland]]&quot;, esp. the section on &quot;[[w: Sudetenland#Within the Czechoslovak Republic (1918–1938)|Within the Czechoslovak Republic (1918–1938)]]&quot;, accessed 2026-05-05.&lt;/ref&gt; If those ethnic Germans had used nonviolent noncooperation to highlight their grievances, and if Czechoslovakia at that time had had a substantially more diverse media system, it seems likely that they could have gotten reasonable redress of grievances. If so, it would have been harder for Hitler to use that as an excuse to invade Czechoslovakia, as he did in 1938.&lt;ref&gt;Wikipedia, &quot;[[w:Occupation of Czechoslovakia (1938–1945)|Occupation of Czechoslovakia (1938–1945)]]&quot;, accessed 2026-05-05.&lt;/ref&gt; 

In 1940, during World War II, Germany invade Denmark, which had previously declared neutrality. The Germans allowed [[w:1943 Danish Folketing election|Danish parliamentary elections in 1943]]. A Danish Nazi party won on 2.1% of the votes.&lt;ref&gt;{{cite web|title=Rigsdagsvalgene i Marts og April 1943|url=http://www.dst.dk/pukora/epub/upload/20217/valg1943.pdf|date=|publisher=Danmarks Statistic|accessdate=11 February 2021}}&lt;/ref&gt; When the Nazis ordered the Danes [[w:Rescue of the Danish Jews|to ship their Jews to the death camps, the Danes ignored those orders.]] When the Germans decided to do it themselves, a German diplomat leaked that decision, and nearly all Danish Jews escaped to neutral Sweden; 99% of Denmark's Jewish population survived the Holocaust.

An ideal settlement of the current Russo-Ukraine war might include training in nonviolent noncooperation made more effective through a more diverse media culture as suggested above. A substantial portion of the Ukrainian population, especially the Ukrainian military, are reported to be vicious anti-Russian Nazis, and the Ukrainian government has outlawed many uses of non-Ukrainian languages, especially Russian.&lt;ref&gt;Horton (2024).&lt;/ref&gt; A campaign of nonviolent noncooperation with a vigorous, diverse adversarial press would likely make it harder for Ukraine to continue any persecution of Russian speakers. It would also make it harder for major media in the US and Western Europe to suppress honest discussion of anti-Russian racism in Ukraine. Swanson (2022) said that the [[w:Baltic states|Baltic states]] have implemented such training in preparations for a possible Russian invasion; they might be asked to support such training in Ukraine (and elsewhere).&lt;ref&gt;Swanson (2022).&lt;/ref&gt; 

Organizations offering training in [[w:Nonviolent resistance|nonviolent noncooperation]] include [[w:Nonviolence International|Nonviolence International]] and the [[w:Highlander Research and Education Center|Highlander Research and Education Center]]. 

=== Civil resistance deters fracking ===

Duhamel (2013) claimed that well-advertised planning and training in nonviolent noncooperation helped deter oil companies from attempting hydraulic fracturing in [[w:Quebec|Quebec Province]] in [[w:Canada|Canada]]. Deterring a foreign invasion is different, but the same principle should apply: It's clear from many sources that elites consider nonviolence a threat; it's a felony to teach nonviolence to someone whom the US State Department claims supports a &quot;foreign terrorist organization&quot;, discussed in the next section.  

=== Life in prison for teaching nonviolence ===

Per the US Supreme Court decision in ''[[w:Holder v. Humanitarian Law Project|Holder v. Humanitarian Law Project]]'' (2010), teaching nonviolence to anyone whom the US State Department claims supports a foreign terrorist organization is &quot;[[w:Providing material support for terrorism|providing material support for terrorism]]&quot;, which is a felony under the USA [[w:Patriot Act|Patriot Act]] of 2001. Moreover, if the State Department claims that the death of any &quot;person&quot; resulted from the activities of the designated foreign terrorist organization, the penalty can be life in prison, where &quot;person&quot; is defined in the Patriot Act as &quot;any individual or entity capable of holding a legal or beneficial interest in property&quot;.&lt;ref&gt;The treatment of [[w:Sami Al-Arian|Sami Al-Arian]] is worth noting in discussing the Patriot Act. Al-Arian is a Kuwaiti-born political activist of Palestinian origin, who earned a doctorate in Electrical Sciences and Systems Engineering at [[w:North Carolina State University|North Carolina State]] in 1985 and taught computer engineering at [[w:University of South Florida|University of South Florida]] (USF) beginning in 1986. He was granted permanent resident status in 1989. In 1993 he earned a Distinguished Teacher Award as a tenured associate professor at USF. He was an [[w:imam|imam]] in a local [[w:mosque|mosque]] and led in other initiatives to promote dialogue and public policy initiatives between the West and Middle East. On September 26, 2001, he appeared on ''[[w:The O'Reilly Factor|The O'Reilly Factor]]'' where he was confronted with a 1988 recording of him shouting &quot;death to Israel&quot;. Al-Arian replied that &quot;Death to Israel&quot; meant &quot;death to occupation, ... apartheid, ...oppression,&quot; whereupon O'Reilly cut him off and called for the [[w:Central Intelligence Agency|Central Intelligence Agency]] to investigate him. Al-Arian spent most of the next 14 years between that 2001 interview and 2015 in detention, much of it in solitary confinement. This period included a 2005 trial that ended with acquittal on 8 counts and a hung jury on another 9. In 2015 he was deported to Turkey. In 2017, he founded the Center for Islam and Global Affairs at [[w:Istanbul Sabahattin Zaim University|Istanbul Sabahattin Zaim University]] in Istanbul, Turkey, which he directs. What has been the impact of treatment of Al-Arian on the well-being of the bottom 99 percent of the US and world population?&lt;/ref&gt; 

How did these provisions get written into the Patriot Act? 

That's a question that deserves research, perhaps by asking elected officials in the US Congress and lobbying for their repeal. A speculation consistent with the thesis of this book is that nonviolence terrifies those who control most of they money for the media, because it threatens their ability to get their security forces to follow orders.

==3. Forbid uses of force beyond one’s own borders and covert interference in foreign countries ==

:''[[w:Si vis pacem, para bellum|If you want peace, prepare for war.]]''
:  -- ''[[w:De Re Militari|De Re Militari]]'' by [[w:Publius Flavius Vegetius Renatus|Publius Flavius Vegetius Renatus]] (fourth or fifth century AD)

The record of history is now clear: Those who prepared for war often got war initiated when one party claimed they were being attacked or about to be attacked and believed they would fare better by attacking. Sometimes this occurred when the media environment convinced leaders that their political futures required them to clandestinely provoke foreign entities to do things that could then be denounced as unprovoked to justify military escalation, as mentioned in the previous section.  

Samuelson (2025) summarized quantitative analyses of 60 insurgencies since World War II, whose findings included the complete absence of success with counterinsurgencies without large force ratios (at least four, and most often more than ten, times the force of the insurgents) and without &quot;providing a path toward peaceful addressing of grievances&quot;. He also noted that, &quot;Brutality toward the civilian population ... tends to inflame the insurgency.&quot;&lt;ref&gt;Samuelson (2025) summarized Lawrence (2015).&lt;/ref&gt; His analysis gave a pessimistic prognosis for the [[w:Gaza war|Gaza war]] that began 2023-10-07. His conclusions are consistent with the history of the current [[w:Russo-Ukrainian war|Russo-Ukrainian war]], the [[w:Vietnam War|Vietnam War]], the [[w:Graveyard of empires|First, Second, and Third Anglo-Afghan Wars (1839-1919), the Soviet-Afghan War (1979–1989), the US-led War in Afghanistan (2001–2021)]], the 2001-2011 [[w:Iraq War|Iraq War]], and others. 

A key point is that invaders often to lose unless they enter with overwhelming force like Germany in the early stages of World War II: The [[w:Occupation of Czechoslovakia (1938–1945)|Czechoslovaks]], [[w:Invasion of Poland|Poles]], [[w:France during World War II|French]], and others were not prepared to fight the Germans, but the [[w:Soviet Union in World War II|Soviets]] were. [[w:Adolf Hitler|Hitler]] doubtless knew that the [[w:Switzerland during World War I and World War II|Swiss]] were prepared to fight, so he attacked other countries first. While fighting the [[w:Russo-Ukrainian war#Full-scale Russian invasion of Ukraine (2022)|Russian invasion]] that began 2022-02-24, [[w:Defense industry of Ukraine|Ukraine has developed]] military drones that are highly effective relative to the cost, as witnessed by sales of such to Gulf Arab states,&lt;ref&gt;Sharawi and Shapiro (2026).&lt;/ref&gt; illustrating the point that foreign invaders often encounter vastly more resistance than they expect -- and should expect highly effective resistance if they invade a country prepared to fight on their own territory. 

The rest of this section discusses weaknesses with standard deterrence theory. 

===Deterrence theory and nuclear Armageddon=== 

Standard [[w:Deterrence theory|deterrence theory]] assumes that one's opponents are rational and do not want [[w:Armageddon|Armageddon]]. The record of history summarized above raises questions about this assumption: In World War I, even the &quot;winners&quot; arguably lost more than they gained -- doubtless excepting a few merchants, who made fortunes from what they sold. Many of the other military decisions discussed above seem to have been driven more by the media than military necessity. 

Beyond that, at least some portions of the [[w:Islamic State|Islamic State]] reportedly violates this assumption, because it &quot;not only believes in the literal meaning of the coming Armageddon – it sees itself as its chief protagonist.&quot;&lt;ref&gt;Misra (2015).&lt;/ref&gt; Some [[w:Christian nationalism|Christian nationalists]] promoted to command positions by [[w:United States Secretary of Defense|US Secretary of Defense]] [[w:Pete Hegseth|Hegseth]] and President Trump also seem to believe that Armageddon might be desirable. On 2026-03-03 the [[w:Military Religious Freedom Foundation|Military Religious Freedom Foundation]] said they had received over 200 complaints from over 50 different US military installations with comments like, &quot;President Trump has been anointed by Jesus to light the signal fire in Iran to cause Armageddon and mark his return to Earth&quot;, per an email from one [[w:Non-commissioned officer|NCO]].&lt;ref&gt;Nick Mordowanec (2026).&lt;/ref&gt; With Hegseth holding monthly Christian worship services in the Pentagon during business hours,&lt;ref&gt;Black (2025), Mayes-Osterman (2025). See also the section on &quot;[[w:Pete Hegseth#Pentagon Christian worship services and &quot;biblically sanctioned war&quot;|Pentagon Christian worship services and &quot;biblically sanctioned war&quot;]] in the Wikipedia article on [[w:Pete Hegseth|Pete Hegseth]], accessed 2026-05-14.&lt;/ref&gt; this suggests that Hegseth could have appointed enough Christian nationalists to key positions to initiate nuclear attacks on Iran or Russia, claiming that President Trump had ordered such whether he had or not.&lt;ref&gt;The [[w:Gold Codes|Gold Codes]] carried in the &quot;[[w:nuclear football|nuclear football]]&quot; required by the [[w:Permissive action link|permissive action link]]s would ''not'' prevent Hegseth and a few others appointed by him from initiating nuclear Armageddon, according to Ellsberg, who had been a nuclear war planner for presidents Eisenhower, Kennedy, Johnson, and Nixon, before releasing the ''[[w:Pentagon Papers|Pentagon Papers]]''. Ellsberg (2017, p. 69) insisted that the security provided by those Gold Codes were a hoax, because otherwise a single nuclear detonation on Washington, DC, when both the president and vice president were in town &quot;would would definitively block any authorized, coordinated nuclear response to that or any subsequent nuclear attack.&quot;&lt;/ref&gt; 

The biggest risk today may be the risk of [[w:Nuclear holocaust|nuclear Armageddon]], which seems on average to grow over time consistent with experience with &quot;[[w:system accidents|system accidents]]&quot; in other fields: It is naive to assume that any system as complex as military command, control and communications systems never fail. And managers of complex systems subject to rare, catastrophic failures &quot;learn&quot; from experience that they can take ever greater risks, because they have &quot;safely&quot; done so in the past — until there is a catastrophe:&lt;ref&gt;Kahneman and Klein (2009) found that expert intuition, when it exists, is learned from frequent, rapid, high quality feedback. With anything nuclear, mishaps are so rare that managers develop &quot;expert intuition&quot; that they can &quot;safely&quot; ignore safety concerns -- until there is a catastrophe. See also Sagan (1993).&lt;/ref&gt; 

Veterans for Peace (2022) recommend global reduction and rapid elimination of nuclear weapons &quot;to reduce the real risk of nuclear confrontation through accidental launch or miscalculated escalation&quot;. 

==== National security tariffs ====

Free trade agreements supported by the [[w:World Trade Organization|World Trade Organization]] allow exemptions for national security and other objectives. [[Responding to a nuclear attack|Even a minor nuclear war between India and Pakistan would have a negative impact on the entirety of humanity]]. It might therefore be sensible for parties to the [[w:Treaty on the Prohibition of Nuclear Weapons|Treaty on the Prohibition of Nuclear Weapons]] (TPNW) to institute gradually increasing tariffs on nuclear weapon states, not so great as to seriously impact the economy of the nation applying such tariffs but aggressive enough to gradually wean their economy from reliance on trade with nuclear-weapon states that refuse to support the TPNW.

===Research on the effectiveness of deterrence and implications=== 

Lebow and others have provided substantial documentation of case studies claiming that leaders are often not rational, and deterrence based on threatening use of military force beyond one’s own borders has been ''as likely to provoke as prevent'' undesired behavior.&lt;ref&gt;Lebow (2025, 2024), Lebow et al. (2023).&lt;/ref&gt; The most obvious portions of this threat can be entirely eliminated by policies clearly and effectively forbidding use of force beyond one’s own borders. This can be signaled in at least three ways: 

* Eliminate all weapon systems like missiles and aircraft with a range of more than, e.g., a hundred miles or 200 kilometers with the possible exception of surveillance only aircraft that cannot be easily configured to carry [[w:Materiel#Military|ordnance]], e.g., explosives. Similarly eliminate nuclear weapons, which few if any countries would want to use for military defense inside their own borders. 

* Supply a national guard and reserves with weapons, training, and rules of engagement that prohibit projecting force beyond one’s own borders. Train them also in development and use of improvised explosive devices and other tactics and devices like low cost military drones. 

:Afghanistan is said to be the &quot;[[w:Graveyard of empires|Graveyard of empires]]&quot;. They defeated the British three times (1839–1842, 1878–1880, 1919), the Soviet Union (1979–1989), and the US (2001–2021). Each victory came with foreign supplies, but any foreign troops helping Afghanis were primarily under the command of local leaders. 
:The [[w:2003 invasion of Iraq|2003 invasion of Iraq]] might have produced [[w:Nation-building|nation-building]] more like the experience of [[w:Nation-building#Germany and Japan after World War II|Germany and Japan after World War II]] if the US had mandated a vigorous adversarial press instead of strict censorship, according to McChesney and Nichols.&lt;ref&gt;McChesney and Nichols (2010, Appendix II. Ike, MacArthur and the Forging of Free and Independent Press, pp. 241-254).&lt;/ref&gt; This claim by McChesney and Nichols was not endorsed by [[News from Germany 1900-1945 and implications for today#After the war in Germany vs. Iraq|University of British Columbia History professor Heidi Tworek]], who said the democratization efforts in Germany and Japan after World War II were more complicated than that implied by that brief discussion by McChesney and Nichols.&lt;ref&gt;The 2025-07-03 interview with Tworek is available at &quot;[[News from Germany 1900-1945 and implications for today]]&quot;, accessed 2026-05-14.&lt;/ref&gt; However, the research by Usher and Kim-Leffingwell (2022) and the related research on news deserts summarized in the preface to this ''[[Media Literacy and You]]'' book largely supports those claims by McChesney and Nichols.
:[[w:Defense industry of Ukraine|Ukraine has become a world leader in military drones]], many of which are dramatically cheaper than alternatives. Most of those have limited range but have been useful for reconnaissance and delivery of ordnance and improving targeting of, e.g., surface to air missiles. 
:[[w:Eliot A. Cohen|Eliot Cohen]], who served as a special advisor to [[w:United States Secretary of State|US Secretary of State]] [[w:Condoleezza Rice|Condoleezza Rice]] from 2007 to 2009, wrote, &quot;As the United States discovered in Iraq and Afghanistan, no matter how large, technologically advanced, and proficient an army is, motivated insurgents can still inflict casualties in the tens of thousands.&quot;&lt;ref&gt;Cohen (2022), cited from Horton (2024, p. 1026).&lt;/ref&gt; Cohen recommended we &quot;Arm the Ukranians now&quot;. Horton said that the neoconservatives learned from Iraq War II and Afghanistan that the US &quot;should fight like those who defeated them.&quot;&lt;ref&gt;Horton (2024, p. 1026).&lt;/ref&gt; 
:Leading economist [[w:Jeffrey Sachs|Jeffrey Sachs]] addressed the European Parliament 2025-02-19, claiming that the tragedy that befell Serbia in 1999 and subsequent US uses of force in Iraq and Syria, plus wars in Africa including Syria, Somalia and Libya and the current wars in Ukraine and the Israel-Hamas war, &quot;are to a very significant extent the result of deeply misguided US policies.&quot;&lt;ref&gt;Sachs (2025-02).&lt;/ref&gt; He said that Europe should craft its own foreign and military policies, independent of the US. ''[[w:Le Monde Diplomatique|Le Monde Diplomatique]]'' noted that Sachs' speech has circulated among social media since ''but has yet to be seriously discussed by major European media.''&lt;ref&gt;Sachs (2025-04; emphasis added).&lt;/ref&gt; 

* Change the laws of government secrecy so government officials cannot secretly interfere in the internal affairs of foreign countries or otherwise project force outside their own borders. This might be achieved in the US in part by requiring anyone with information about questionable actions by government officials to provide such documentation to one or more congressional oversight bodies while also allowing any current or former government employee or contractor to file suit in any US federal jurisdiction if they feel they have been punished for refusing to support questionable activities. In addition, federal judges should be authorized to subpoena classified government documents that may be relevant to any case in their jurisdiction and declassify them subject to appellate review if they believe the national interest would be better served by declassification. 

:If the law is changed without a substantive [[#1. Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content.|citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference]], as discussed above, the change could be merely cosmetic and unconvincing to local public officials and potential adversaries. 
:Connelly (2023) noted that US government secrecy has in the past encouraged administration officials to do things to provoke actions by foreign entities that can then be denounced as “unprovoked” to stampede the US Congress and the public into supporting counterproductive uses of military force, as discussed above.&lt;ref&gt;See also Connelly et al. (2023).&lt;/ref&gt; A more diverse media culture should make it harder for administration officials to lie to the public and to Congress — and harder to punish government employees who tell their managers that they should not lie to Congress, as they reportedly did to [[#Richard Barlow and nuclear proliferation|Richard Barlow]], mentioned above. 
:The Barlow case and many others explain why the US should, e.g., give federal judges the authority to subpoena classified documents and declassify them if they believe the public good is better served from declassification than continued secrecy.&lt;ref&gt;See, e.g., the 2025-05-08 interview with Seth Stern and Lauren Harper discussing what the &quot;[[Freedom of the Press Foundation says...]]&quot;, Graves (2014), and [[w:Moynihan Commission on Government Secrecy|Moynihan Commission on Government Secrecy]], accessed 2026-05-06. Graves (2021) recommends &quot;Congressional Gold Medals for&quot; Barlow and whistleblowers.&lt;/ref&gt; 

These policies would make it hard for any foreign leader to justify an attack for multiple reasons: First, it would be difficult to convince their supporters that such an attack is necessary. Second, a rational foreign leader might be hesitant to invade a country that is prepared to fight a guerrilla war. Germany reportedly considered invading [[w:Switzerland during World War I and World War II|Switzerland during both World Wars I and II]] and decided against it in part because Switzerland had large, well-trained ready reserves, who were ready to fight. Belgium seemed to be an easier route.&lt;ref&gt;Documented in Wikipedia, &quot;[[w:Switzerland during World War I and World War II|Switzerland during World War I and World War II]]&quot;, accessed 2026-05-06. Switzerland also has many mountains, which make it easier to defend, but the capabilities of the Swiss military also influenced the German decision to avoid Switzerland.&lt;/ref&gt; Third, even if foreign invaders defeat the guerrillas, they should not assume that their invading forces would continue to follow orders. [[w:Rescue of the Danish Jews|Ninety-nine percent of Danish Jews reportedly survived World War II]] because of Danish noncooperation ''supported by a German diplomat''.&lt;ref&gt;Wikipedia, &quot;[[w:Rescue of the Danish Jews|Rescue of the Danish Jews]]&quot;, accessed 2026-05-06.&lt;/ref&gt; 

With policies like these in place, it would be hard for foreign leaders to convince their supporters of a need to attack, as [[w:2022 Russian invasion of Ukraine|Putin did when invading Ukraine in 2022]],&lt;ref&gt;The Wikipedia article on &quot;[[w:2022 Russian invasion of Ukraine|2022 Russian invasion of Ukraine]]&quot;, accessed 2026-05-06, includes a paragraph saying, 'In July 2021, Putin published an essay &quot;On the Historical Unity of Russians and Ukrainians&quot;, in which he called Ukraine &quot;historically Russian lands&quot; and claimed there is &quot;no historical basis&quot; for the &quot;idea of Ukrainian people as a nation separate from the Russians&quot;'. Putin was accused of promoting Russian imperialism, historical revisionism and disinformation. Writing in 2024, Michael McFaul and Robert Person described this essay as representing not only &quot;cynical propaganda&quot; but also Putin's &quot;deeply held and internalized beliefs&quot;. See the Wikipedia article for references supporting those claims.&lt;/ref&gt; as [[w:2025 India–Pakistan crisis|India did when attacking Pakistan in 2025]], and as [[w:Invasion of Poland|Hitler did when invading Poland in 1939]], to name only three examples. 

=== If we continue to base deterrence on threats === 

There are now calls for Europe to get their own nuclear weapons,&lt;ref&gt;Burgard (2025).&lt;/ref&gt; while Iran, Saudi Arabia, Turkey, South Korea and Taiwan have been suggested as other candidates for acquiring nuclear weapons should they feel a sufficient need.&lt;ref&gt;Ruehl (2024).&lt;/ref&gt; 

It is difficult to imagine how the number of nuclear weapon states could be increased without increasing the risks of a nuclear war, consistent with the discussion of &quot;[[w:system accident|system accident]]s&quot; earlier in this chapter.

Secondarily, intelligence services with information on political corruption including attempts to intimidate and murder journalists should not be allowed to keep that information secret: They should be required to find ways to leak that information to journalists. Such attacks on journalists in their own country should be exposed and prosecuted if the evidence seems likely to obtain a conviction. Intelligence services with information about such attacks in other countries should be required to find ways to leak it to competent journalists without identifying their sources and methods: Doing so would likely reduce political corruption worldwide and with that the risks of war. 

== Collateral damage ==

The research cited above supports the claim that, 

:''[[w:Collateral damage|Collateral damage]] that our designated enemies commit prove to us that they are subhuman or criminally misled.''
:''Meanwhile, collateral damage that we commit is unfortunate but necessary -- from our perspective. However, it proves to our designated enemies that we are subhuman or criminally misled.'' 

This observation supports this entire program of deterrence without threat: 
* Forbidding use of force beyond one’s own borders and covert interference in foreign countries would automatically reduce collateral damage. It would also avoid uses of force that seem not to contribute to broadly shared peace and prosperity, according to research cited above. 
* The effectiveness of nonviolent noncooperation rests in part on its near universal avoidance of collateral damage. 
* Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content should make it much harder for major media to convince the public to do things contrary to their best interests, like invading or interfering covertly in foreign countries. 

== Call for help == 

Do you, dear reader, know other serious research not cited herein that might improve this analysis? If yes, you can help improve this discussion by adding comments with citations -- or by adding such citation(s) to the &quot;Discuss&quot; page associated with this chapter, suggesting someone else revise the chapter appropriately. 

There are plenty of contrary claims in the major media, but the lead author of this chapter is not aware of any that are based on serious research. 

In the absence of such research, the current author finds it difficult to imagine any national defense policies that carry a greater risk of nuclear Armageddon than our current policies, as discussed in the next chapter of this book on ''[[Media Literacy and You]]'' on &quot;[[Media Literacy and You/Responding to a nuclear attack|Responding to a nuclear attack]]&quot;. That chapter, in sum, claims that the ''worst'' response to a nuclear attack would be nuclear response, because it would escalate a catastrophe killing millions of humans to one killing ''billions'', possibly 80 percent of humanity in a war between the US and Russia that lofts so much smoke from burning cities to the stratosphere where it covers the globe depressing crop yields for years during with 99 percent of the humans in the US, Europe and Russia would starve to death if they did not die of something else sooner. Moreover, the record of &quot;[[w:System accident|system accident]]s&quot; suggests that the chances of such a war before the end of this century is substantially greater than the 40 percent median estimate based on history mentioned in a presentation on &quot;[[Time to nuclear Armageddon]]&quot; delivered to the 2019 Joint Statistical Meetings. 

This chapter is being written in the hopes of inspiring action to improve the prospects for broadly shared peace and prosperity for the long term. 

== Exercises ==

1. Disconfirmation bias: Brainstorm your biggest concerns about a current or possible future war. 
:1.1. Select the one that is of greatest concern to you currently. 
::One issue that may not be a major concern for many but might elicit a broad consensus for action would be a campaign to ask elected officials in the US Congress to explain how we benefit from the provisions of the USA Patriot Act of 2001 that authorize [[#life in prison for teaching nonviolence|life in prison for teaching nonviolence]]. 
:1.2. Who are your designated enemies? 
:1.3. Research what your designated enemies are saying about your biggest concern.  
:1.4. Under what circumstances would you support what you see your designated enemies advocating or doing? 
::If you cannot see such circumstances, expand your research: Look for more sources that support your designated enemies. 

2. Interacting: Ask others if you can share what you've learned about that conflict. If they say, &quot;No&quot;, don't push it. If they agree, share what you've learned in a friendly supportive manner without saying that anything is &quot;true&quot;. 

::''Show me someone who knows the truth, and I will show you someone who is dangerous.''

:2.1. The primary goal in this is ''not'' to convince anyone that you are right and they are wrong but to lower the level of anger and increase the level of tolerance for dissenting views. 
:2.2. Another goal is to comfortably enjoy civil conversations of this nature, agreeing to disagree agreeably and building trusting relationships that support collaboration on issues of common concern. 
:2.3. After becoming adept at building collaborations on issues of common concern, you might consider teaching this important skill and approach to issues.  

3. Teaching: Each one teach two, as discussed in the section on &quot;[[Media Literacy and You#Text and self-help book and point of discuss|Text and self-help book and point of discuss]]&quot; in the preface to this book.

:''Humanity is one misunderstanding, one miscalculation away from nuclear annihilation. ... This is madness. We must reverse course.''
:  -- [[w:António Guterres|UN Secretary General António Guterres]]  (2022)&lt;ref&gt;Jacobsen (2024), BBC (2022).&lt;/ref&gt;

:This book is a combination instruction manual on [[w:Media literacy|media literacy]] and an invitation to you to support collaborative / crowd-sourced research on how to improve the world's understanding of media literacy and how to accelerate its understanding and use globally for the betterment of humanity. 

Part I of this book on ''[[Media Literacy and You]]'' discusses &quot;The media and political economy&quot;. Except in times of terror, massive lawlessness or war, most humans place a high priority on their financial situation, the primary focus of Part I. Part II on &quot;The media and war&quot; focuses on security concerns starting with this chapter on &quot;Deterrence without threat&quot;. 

== Introduction ==

Every individual and group has a right and an obligation to defend itself. Unfortunately, when most humans&lt;ref&gt;We distinguish here between &quot;humans&quot; and &quot;people&quot; or &quot;persons&quot;, because under current US law, corporations are &quot;people&quot; and money is speech, per the US Supreme Court decision in ''[[w:Citizens United v. FEC|Citizens United v. FEC]]'' (2010) and many other judicial rulings and US law such as the [[w:Patriot Act|Patriot Act]] of 2001.&lt;/ref&gt; think of defense, they often think of violent responses to provocations. 

However, there is a growing body of research documenting 

:(a) how most uses of violence are counterproductive, and 
:(b) there are usually nonviolent options to violence that would more effectively promote broadly shared peace and prosperity for the long term. 

This research is rarely discussed by major media outlets, because it would offend the &quot;people&quot;&lt;ref&gt;We put &quot;people&quot; in quotes in this essay, because that term includes corporations under current US law.&lt;/ref&gt; who control most of the money for the media: Nonviolence threatens their ability to get compliance from security forces. As a result, many elites prefer to use force to the detriment of the bottom 99 percent of humanity. As discussed below, a military posture that supports projecting force beyond one’s own borders may be as likely to ''provoke'' as ''prevent'' an attack.&lt;ref&gt;For example, Lebow (2025) cites some of his previous work with others to support the claim that large militaries have been &quot;more provocative than preventative in&quot; their effects. And Lebow (2024) insists that, &quot;Policymakers respond more instinctively than analytically in deciding that some policy is or is not in the national interest.&quot; See also Lebow et al. (2023).&lt;/ref&gt; 

This chapter outlines a 3-part strategy that research suggests would more likely lead to better outcomes for the vast majority of humans: 

# Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content. 
# Training in nonviolent noncooperation for anyone willing to listen. 
# Forbid uses of force beyond one’s own borders and covert interference in foreign countries. 

We now discuss each of these briefly. 

== 1. Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content. == 

It seems that

:''Primary drivers of every major conflict include differences between the media that the different parties find crecible.''

In a recent interview with [[w:Fordham University|Fordham University]] Professor Emerita of Communications Robin Andersen,&lt;ref name=Andersen&gt;&lt;!--Robin Andersen--&gt;{{cite Q|Q132982358}}&lt;/ref&gt; she agreed with this claim and added: 

:''We only have enemies of our very own making.''

The media are involved in this, because:  

:''The major media create the stage upon which politicians read their lines.''&lt;ref&gt;In 1791 James Madison, who represented part of Virginia in the US House of Representatives 1789-1801 and later became the 4th President of the US (1809-1819), said, &quot;Public opinion sets bounds to every government, and is the real sovereign in every free one.&quot; Quoted from the ''[[w:National Gazette|National Gazette]]'' (published 1791-1793) by Schmeller (2009, p. 36) and Sauer (2016, p. 5). Sauer described how the American Revolutionaries, especially the first four US presidents, planted stories in newspapers to build support for how they dealt with the [[w:Barbary corsairs|Barbary pirates]], who were seizing merchant ships, raiding European coastal towns and villages, and selling European captives into slavery. The first two US presidents, [[w:George Washington|Washington]] and [[w:John Adams|Adams]], used that support for protecting US shipping and citizens by paying tribute to government leaders in Morocco, Algeria, Tunisia, and Libya. The next two presidents, [[w:Thomas Jefferson|Jefferson]] and [[w:James Madison|Madison]], convinced Congress to fund a navy and marines to fight the [[w:Barbary Wars|Barbary Wars]]. This included the [[w:Battle of Derna (1805)|Battle of Derna]]  (April-May 1805), memorialized in the [[w:Marines' Hymn|Marines' Hymn]], which mentions actions &quot;to the shores of Tripoli&quot;. Sauer described how the policies were sold to the public via planted stories in the different partisan newspapers.&lt;/ref&gt; 

This works because (a) virtually everyone thinks they know more than they do ([[w:Overconfidence effect|overconfidence effect]]), and (b) virtually everyone prefers information and sources consistent with preconceptions ([[w:confirmation bias|confirmation bias]]). 

Also, in many, perhaps all, countries, the primary constituency for foreign and military policy is the people with foreign business interests. Many of these people also control substantial portions of the money for the media, which have too often encourage questionable and counterproductive uses of military force.&lt;ref&gt;If we [[w:follow the money|follow the money]], we might find that &quot;watchdogs generally protect the people who feed them&quot;, as discussed in the 2025-09-25 interview with British journalist and media reform activist Dan Hind discussing how the British [[Media Reform Coalition challenges anti-democratic media bias in the UK]].&lt;/ref&gt; 

=== Examples === 

A leader in documenting the role of the media in armed conflict is Robin Andersen,&lt;ref&gt;e.g., Andersen (2006, 2026).&lt;/ref&gt; but she is not alone. For example, [[w:University of Denver|University of Denver]] journalism professor Kareem El Damanhoury&lt;ref name=Daman&gt;&lt;!--Kareem El Damanhoury--&gt;{{cite Q|Q113752441}}&lt;/ref&gt; has compared how [[w:Gaza Strip|Gaza]] has been framed differently by [[w:Al Jazeera Media Network|Al Jazeera]], the [[w:BBC|BBC]]&lt;ref&gt;El Damanhoury et al. (2025).&lt;/ref&gt; and [[w:Fox News|Fox]].&lt;ref&gt;El Damanhoury and Saleh (2024).&lt;/ref&gt;&lt;ref&gt;Some of El Damanhoury's work in this regard [[Differences between media outlets including coverage of Gaza|is reviewed in a 2025-11-20 interview with him]].&lt;/ref&gt; 

==== World War I ====

Andersen's (2006) ''A Century of Media, A Century of War'' begins with a discussion of &quot;The birth of war propaganda&quot; in &quot;The Great War and the Fight between Good and Evil&quot;.&lt;ref&gt;Andersen (2006, ch. 1)&lt;/ref&gt; 

A more detailed but compatible discussion of the media and [[w:World War I|World War I]] is given by [[w:John Maxwell Hamilton|John Maxwell Hamilton]]. Among other things, he said: {{quote|

The first iron law of propaganda is that only the enemy does it.&lt;ref&gt;Hamilton (2020, p. 642). See also the [[John Maxwell Hamilton on American propaganda|2025-12-11 interview with Hamilton]].&lt;/ref&gt;}} 

[[File:MB Walker - German bayoneting children - Life - July 25, 1915.png|thumb|left|Figure 1. Stories of German soldiers impaling children on their bayonets were widely reported during the war. However, no credible evidence was found to support these claims when questions were raised after the war.&lt;ref&gt;{{cite web|title=Alleged German atrocities: Bryce report|url=http://www.nationalarchives.gov.uk/pathways/firstworldwar/spotlights/p_alleged_german.htm|publisher=The National Archives|access-date=13 July 2014}}&lt;/ref&gt;]]

Andersen (2006, pp. 8-9) said, {{quote|

James Bryce, the former British ambassador to the United States, ... helped prepare a sixty-one page ''Report on the Committee on alleged German Outrages'', which was translated into thirty languages and was said to be based on twelve hundred depositions ... included gruesome and titillating details of how German soldiers publicly raped Belgian girls in the marketplace at Liege and bayonetted a two-year-old child. ... [A]fter the war a Belgian commission of inquiry found no evidence for any major accusation in the report. ...}}
{{quote|
German propagandists, on the other hand, ... &quot;bungled, because they were naïve: they thought the success of the war depended almost solely on military strategy and therefore they tended to neglect propaganda.&quot; ... Thus, when German soldiers shot some Allied nurses who had carried weapons, they admitted it openly. The Allies reported the incident as an atrocity and featured it in press propaganda. When French troops shot German nurses under similar circumstances, the Germans failed to exploit it.}} 

==== Jonathan Swift 1710 ====

This is not limited to World War I. In 1710, [[w:Jonathan Swift|Jonathan Swift]] reportedly said, &quot;Falsehood flies, and truth comes limping after ... like a physician, who hath found out an infallible medicine, after the patient is dead.&quot;&lt;ref name=Swift&gt;Excerpted from a line in [[Wikiquote:Jonathan Swift]] consulted 2026-04-13.&lt;/ref&gt;  

==== The Marines' Hymn ====

The [[w:Marines' Hymn|Marine Corps Hymn]] begins, {{quote|

From the Halls of Montezuma

To the shores of Tripoli;

We fight our country's battles

In the air, on land, and sea.}}

The &quot;[[w:Battle of Chapultepec|Halls of Montezuma]]&quot; refer to the [[w:Mexican–American War|Mexican–American War]], which was fought to expand slavery first into [[w:Texas|Texas]]  -- and supporters of slavery hoped that would help expand slavery further west. The &quot;[[w:Battle of Derna (1805)|shores of Tripoli]]&quot; were part of the [[w:Barbary Wars|Barbary Wars]], which were fought to reduce the need to pay (a) tribute to the [[w:Barbary Coast|Barbary or Berber]] states of [[w:Morocco|Morocco]], [[w:Algeria|Algeria]], [[w:Tunisia|Tunisia]], and [[w:Libya|Libya]] or (b) ransom to [[w:Barbary corsairs|Barbary pirates]], who were otherwise capturing Christians and selling them into slavery. 

Did the bottom 99 percent of the US population of that time benefit? Or did these wars (and any tribute and ransom paid by the US government before the Barbary wars) constitute a hidden transfer of wealth from the poor to the wealthy? 

A partial answer to this question is that [[w:tariff|tariff]]s on imported goods covered between 80 and 95 percent of all federal revenue up to 1860, and [[w:excise|excise taxes]] on only a few goods, such as whiskey, rum, tobacco, snuff and refined sugar, made up nearly all the rest.&lt;ref&gt;See the section on &quot;[[w:Excise tax in the United States#Historical background|Historical background]]&quot; in the Wikipedia article on &quot;[[w:Excise tax in the United States|Excise tax in the United States]]&quot;, accessed 2026-05-26.&lt;/ref&gt; The money raised from taxes on income during the Civil War, visible in Figure 3 above, were apparently negligible as a portion of federal revenue during the Barbary Wars and the Mexican-American War.  

==== Gulf of Tonkin Resolution: &quot;Betray the nation or do not get elected.&quot; ====

Regarding the [[w:Vietnam War|Vietnam War]], former president [[w:Dwight D. Eisenhower|Eisenhower]] wrote in his autobiography, which appeared in 1963 (he left the presidency 1961-01-20), that he had never communicated {{quote|

with a person knowledgeable in Indochinese affairs [including Vietnam] who did not agree that had elections been held as of the time of the fighting [leading to the defeat of the French in 1954], possibly 80 per cent of the population would have voted for the Communist [[w:Ho Chi Minh|Ho Chi Minh]].&lt;ref&gt;Eisenhower (1963, p. 372).&lt;/ref&gt;}}

[[w:Joseph McCarthy|Joseph McCarthy]], who had been elected to the US Senate in 1946 and &quot;experienced a meteoric rise in national profile beginning on February 9, 1950, when he gave a&quot; speech during which he said something like, &quot;The [[w:United States Secretary of State|State Department]] is infested with communists. I have here in my hand a list of 205—a list of names that were made known to the Secretary of State as being members of the Communist Party and who nevertheless are still working and shaping policy in the State Department.&quot; McCarthy's mostly baseless claims went largely unchallenged in the media, including accusing the Democrats of &quot;twenty years of treason&quot; for having been allied with the Soviet Union, which took the bulk of casualties during World War II. 

By the end of 1953 with (Republican) Eisenhower as president roughly 11 months, McCarthy was complaining about &quot;''21'' years of treason&quot;, complaining that Eisenhower was not sufficiently aggressive in rooting out the communists who McCarthy claimed were in the government.&lt;ref&gt;Fried (1997, p. 179).&lt;/ref&gt; 

Then the French were defeated by Vietnamese communists 1954-05-07 in the [[w:Battle of Dien Bien Phu|Battle of Dien Bien Phu]]. The [[w:1954 Geneva Conference|1954 Geneva Conference]], which had begun eleven days earlier, 1954-04-26, concluded 1954-07-21 with the &quot;Geneva Accords of 1954&quot;.&lt;ref&gt;The [[w:Battle of Dien Bien Phu|Battle of Dien Bien Phu]], 1954-05-07, effectively ended the [[w:First Indochina War|French Indochina War]]. This led to the [[w:1954 Geneva Conference|Geneva accords of 1954]], officially dated 1954-07-20 but actually signed the following morning. Those accords took effect on three different dates, July 27 and August 1 and 11 in three different sectors of Vietnam. See &lt;!--Agreement on the Cessation of Hostilities in Vietnam--&gt;{{cite Q|Q139676410}}&lt;/ref&gt; Those accords called for UN-supervised elections for July of 1956, when Eisenhower would presumably be campaigning for reelection. Eisenhower doubtless knew that he might lose his bid for re-election in 1956, if the Communist Ho Chi Minh won elections in July of that year. 

:''The consistent suppression of honest portrayal in the major media of that day of the perspective of anyone whom Eisenhower considered &quot;knowledgeable in Indochinese affairs&quot; gave him -- and his successors [[w:John F. Kennedy|Kennedy]], [[w:Lyndon B. Johnson|Johnson]], and [[w:Richard Nixon|Nixon]] -- the choice between betraying the nation or not getting elected.'' 

In this environment, the [[w:Operation 34A|US initiated a series of clandestine operations against North Vietnam]] including infiltrating CIA-recruited spies and supporting attacks against North Vietnam by South Vietnamese commandos.&lt;ref&gt;Paterson (2008).&lt;/ref&gt; This included a raid 1964-07-30 by South Vietnamese commandos on the island of Hòn Mê, roughly 300 km (180 miles) north of the [[w:Vietnamese Demilitarized Zone|Vietnamese Demilitarized Zone]] in the [[w:Gulf of Tonkin|Gulf of Tonkin]], covered by [[w:DESOTO patrol|US naval vessels]] patrolling in that area. Then during a dark and stormy night six days later, US naval vessels opened fire on radar snow, and President Johnson requested and received Congressional approval of the [[w:Gulf of Tonkin Resolution|Gulf of Tonkin Resolution]]; then-[[w:United States Secretary of Defense|US Secretary of Defense]] [[w:Robert McNamara|McNamara]] claimed those attacks were &quot;unprovoked&quot;.&lt;ref&gt;Karnow (1983, p. 375). See also the section on [[w:Gulf of Tonkin Resolution#Congress votes|Congress votes]]&quot; in the Wikipedia article on [[w:Gulf of Tonkin Resolution|Gulf of Tonkin Resolution]], accessed 2026-05-14.&lt;/ref&gt;

In this media environment, only two officials in the US Congress voted against the Gulf of Tonkin Resolution: [[w:Ernest Gruening|Ernest Gruening]] (D-AK) and [[w:Wayne Morse|Wayne Morse]] (D-OR). Gruening lost in his next primary campaign to [[w:Mike Gravel|Mike Gravel]], and Morse lost in his next general election campaign to [[w:Bob Packwood|Bob Packwood]]. These results support the previous claim that the major media give politicians the choice: 

:''Betray the nation, or do not get elected.''

That resolution became the primary authorization for the US war in Vietnam until Congress ended the funding. 

==== Was the Vietnam War lost in Washington or by media biases? ====

[[w:John Mueller|John Mueller]], prolific author, Professor Emeritus of international relations at [[w:Ohio State University|Ohio State University]] and Senior Fellow at the [[w:Cato Institute|Cato Institute]], said that the most effective thing the US did to win the [[w:Cold War|Cold War]] was —

:''nothing'': 

Between the [[w:Fall of Saigon|Fall of Saigon]] in 1975 and the inauguration of [[w:Ronald Reagan|Ronald Reagan]] as President of the US, the US &quot;went into a sort of containment funk: it effectively adopted a policy of complacency (or perhaps of appeasement) as it watched from the sidelines as the Soviet Union … opportunistically gathered a set of Third World countries into its imperial embrace: Angola in 1976, Mozambique and Ethiopia in 1977, South Yemen and Afghanistan in 1978, Grenada and Nicaragua in 1979.&quot;&lt;ref&gt;Mueller (2021,  p. 59).&lt;/ref&gt; Nearly all became major economic and political drains on the Soviets with Afghanistan being the worst. And their Warsaw Pact allies in Eastern Europe became a severe economic drain and psychic problem.&lt;ref&gt;Mueller and Graves (2023).&lt;/ref&gt; 

President Reagan, inaugurated 1981-01-20, had a very different vision of the role of the US in foreign relations from his predecessor, [[w:Jimmy Carter|Jimmy Carter]]. In 1983-06-21 Reagan insisted, &quot;We cannot permit the Soviet-Cuban-Nicaraguan axis to take over Central America&quot;, because the consequences would include &quot;a tidal wave of refugees ... 'feet people' ... swarming into our country.&quot;&lt;ref&gt;Clines (1983).&lt;/ref&gt; 

Other sources&lt;ref&gt;e.g., Andersen (2006, Part II).&lt;/ref&gt; insist the opposite, that the vast majority of deaths in Central America during the Reagan years were poor humans petitioning nonviolently for a redress of grievances, suppressed by terrorist / death squads supported by the Reagan administration largely in violation of laws passed by Congress and signed by President Reagan. On 1986-10-05 [[w:Corporate Air Services HPF821|a Nicaraguan soldier with a surface to air missile shot down a C-123]] cargo aircraft carrying supplies to the Contra roughly 35 miles (56 km) north of Costa Rica. Documents found in the wreckage and a confession by the sole survivor led to the [[w:Iran–Contra affair|Iran-Contra hearings]] the following year, during which Lt. Col. [[w:Oliver North|Oliver North]] insisted, &quot;We didn't lose the war in Vietnam ..., we lost it in this city.&quot;&lt;ref&gt;Andersen (2006, p. 137). See also, Wikipedia, &quot;[[w:Stab-in-the-back myth|Stab-in-the-back myth]]&quot;, accessed 2026-05-13.&lt;/ref&gt; 

The previous section on the &quot;Gulf of Tonkin Resolution&quot; provides an alternative narrative of the Vietnam War: If as Eisenhower claimed, &quot;possibly 80 per cent of the [Vietnamese] population would have voted for the Communist [[w:Ho Chi Minh|Ho Chi Minh]]&quot; if elections had been held there, it's hard to imagine how anyone else could have won without aggressive action that actually ''improved'' the lives of Vietnamese peasants in the South. US-led efforts there were officially designed to win &quot;[[w:Hearts and Minds (Vietnam War)|Hearts and Minds]]&quot; but were implemented with such coercion that the result was the opposite. A cynic might say that it is hard to win people's hearts and minds by killing them. 

====Richard Barlow and nuclear proliferation====

There is also documentation that the US helped Pakistan get nuclear weapons and destroyed the career of an intelligence analyst, [[w:Richard Barlow (intelligence analyst)|Richard Barlow]], for telling his managers they should not lie to Congress about it. Barlow has insisted that neither Pakistan nor North Korea would have nuclear weapons and Iran would not have a nuclear weapons program today, if the US had followed its own laws. Barlow’s claims, including his punishment by administration officials, have been reported in major media outlets&lt;ref&gt;e.g., Stein (2013). See also Wikipedia, &quot;[[w:Richard Barlow (intelligence analyst)|Richard Barlow (intelligence analyst)]]&quot;, accessed 2026-05-06.&lt;/ref&gt; but not in a way that would seriously limit the ability — and need — for administration officials to lie to Congress. 

If Barlow's claims are accurate, it suggests that US government officials violated US obligations under the [[w:Treaty on the Non-Proliferation of Nuclear Weapons|Non-Proliferation Treaty]] (NPT).&lt;ref&gt;Per the [[w:Treaty Clause|Treaty Clause]] of the US Constitution, a treaty negotiated by the President and approved by the Senate has &quot;the force of federal law.&quot;&lt;/ref&gt; 

==== Nayirah testimony and the 1990-1991 Gulf War ====

A more recent example is the 1990-10-10 testimony by [[w:Nayirah testimony|Nayirah al-Ṣabaḥ to the US Congressional Human Rights Caucus]], two months after the Iraqi invasion of Kuwait. She claimed to have seen Iraqi soldiers taking premature babies out of incubators in a maternity ward before looting the incubators and leaving the babies to die on the floor after the Iraqi invasion of Kuwait; she said she had been a volunteer nurse in the hospital at that time. 

The failure of journalists, including with the ''[[w:NBC Nightly News|NBC Nightly News]]'', to adequate check facts behind this and other atrocity stories helped convince the US public to support the US-led invasion of Iraq in 1990-1991. Nayirah's statements were widely publicized and cited numerous times in the United States Senate and by American president George H. W. Bush to contribute to the rationale for pursuing military action against Iraq. It was later revealed that she was the daughter of Kuwaiti ambassador to the US, [[w:Saud Nasser Al-Saud Al-Sabah|Saud Nasser Al-Saud Al-Sabah]], &quot;Reps. [[w:Tom Lantos|Tom Lantos]] and [[w:John Porter (Illinois politician)|John Edward Porter]], who sponsored the congressional hearings, had started a group called the Congressional Human Rights Foundation that had received $50,000 from Citizens for a Free Kuwait, as well as free office space in [[w:Hill &amp; Knowlton|Hill and Knowlton]]'s Washington headquarters&quot;,&lt;ref&gt;Rowse (1992).&lt;/ref&gt; and the public relations firm Hill and Knowlton had made a video while coaching her rehearsing her perjury and used that to prepare a video press release &quot;that eventually reached a total audience of about thirty-five million&quot;, 14 percent of the [[w:Demographic history of the United States|US population of 249 million per the census then in process]], with portions aired on the ''[[w:NBC Nightly News|NBC Nightly News]]'' the night after the testimony.&lt;ref&gt;Andersen (2006, pp. 170-171).&lt;/ref&gt; 

==== 1998 Embassy bombings and September 11 ====

As another example, there is substantial documentation available today that [[1998 Embassy bombings and September 11|the suicide mass murders of September 11, 2001]], likely would not have occurred if the US had treated the 1998 bombings of the US embassies in Kenya and Tanzania as law enforcement issues. Muslim clerics all over the world initially condemned those acts. Al-Qaeda was dead. Their funding had largely dried up. And bin Laden was scheduled to be extradited the following month to Saudi Arabia to be prosecuted for treason, where he would likely have been convicted and executed. Mayer (2008, p. 114) claimed those embassy bombings were motivated as retaliation for US support for torture.&lt;ref&gt;For more on torture, see the the section on [[#Make media responsible for harms|Make media responsible for harms]] below.&lt;/ref&gt; 

But it seemed questionable at best whether major media executives in the US would have given favorable coverage to such a diplomatic solution. Instead, the US bombed a pharmaceutical plant in Sudan and al-Qaeda training camps in Afghanistan. Then Muslim public opinion turned 180 degrees to conclude, &quot;Bin Laden is right: The US ''is'' an evil empire.&quot; The US became bin Laden’s only indispensable ally, according to the CIA agent responsible for tracking bin Laden at that time.&lt;ref&gt;Scheuer (2004, p. xv).&lt;/ref&gt; Leading Saudis started supporting al-Qaeda, including some working for the Saudi embassy and consulates in the US. Only one country seems to have been involved in the preparations for the September 11 attacks, and that was Saudi Arabia. But Saudis were friends of the Bush family, and a crisis is a terrible thing to waste.&lt;ref&gt;Romer (2009).&lt;/ref&gt; 

:''Did the US invade Afghanistan and Iraq on grounds that senior journalists and leading media executives should have known at the time were questionable and likely fraudulent — to the detriment of nearly everyone except the &quot;people&quot; who control most of the money for the media?'' 
:In particular, was Iraqi president [[w:Saddam Hussein|Saddam Hussein]] really a bigger threat to the US after he invaded Kuwait in 1990 or after the [[w:September 11 attacks|suicide mass murders of September 11, 2001]] than he was during the 1980s, when the US supported him [[w:Iran-Iraq War|killing Iranians]] or [[w:Anfal campaign|his own native Kurds]]? 

On 2003-05-29 [[w:BBC|BBC]] journalist [[w:Andrew Gilligan|Andrew Gilligan]] reported that the [[w:Tony Blaire|Blair government]] had &quot;sexed up&quot; [[w:September Dossier|intelligence reports]] issued the previous September to justify supporting the 2003-03-20 [[w:Iraq War|US-led invasion of Iraq]], two months before Gilligan's report. This led to the [[w:Hutton Inquiry|Hutton Inquiry]], which led to the resignations of Gilligan and the BBC's chairman and the firing of the BBC's director-general. However, the British public expressed so many reservations about the Hutton Inquiry that a follow-up investigation was ordered in 2009. This became the &quot;[[w:Iraq Inquiry|Iraq Inquiry]]&quot;, whose 2016-07-06 report essentially validated what Gilligan had said just over 13 years earlier. This provides one more example of the 1710 maxim of Jonathan Swift that, &quot;Falsehood flies, and truth comes limping after ... like a physician, who hath found out an infallible medicine, after the patient is dead.&quot;&lt;ref name=Swift/&gt;

====Ukraine war====

Page 1 of the 2023-05-04 edition of ''[[w:Le Monde Diplomatique|Le Monde Diplomatique]]'' carried a headline: 

:One year after the invasion of Ukraine: The media, vanguard of the war party,&lt;ref&gt;Halimi and Rimbert (2023) in the French-language original.&lt;/ref&gt;

consistent with Andersen (2006).

=== Make media responsible for harms ===

How might the world be different if injured parties could successfully sue major media for harms that result from government policies contradicted by evidence reasonably available to the major media outlets? 

For example, how might the world be different if: 

* combat veterans or their families could successfully sue major media outlets for biased reporting that stampede the nation into ill advised and counterproductive uses of military force on grounds that leading media personalities should have known at the time were questionable and likely fraudulent? 
* Vietnamese or Afghanis or Iraqis or Palestinians or victims in other countries could win similar lawsuits?
* immigrants could sue major media outlets for failing to publish reasonable summaries of the available research that says that immigrants on average are more entrepreneurial&lt;ref&gt;Aghion et al. (2022, pp. 266-270).&lt;/ref&gt; and no more likely to engage in criminal activities than native born, benefitting both the sending and receiving countries?&lt;ref&gt;The Wikipedia article on &quot;[[w:Immigration|Immigration]] cites research saying, &quot;that migration can be beneficial both to the receiving and sending countries. The academic literature provides mixed findings for the relationship between immigration and crime worldwide. ... [P]ublic perception often exaggerates the connection between immigration and crime, influenced by sensationalised media coverage and political rhetoric.&quot; The Wikipedia article on [[w:Immigration and crime|Immigration and crime]] notes that in some countries immigrants are over-represented in prison populations due to violations of immigration law or anti-immigrant biases in criminal justice. The Wikipedia article on &quot;[[w:Sanctuary city|Sanctuary city]]&quot; says that, &quot;Some studies on the relationship between sanctuary status and crime have found that sanctuary policies either have no effect on crime or that sanctuary cities have lower crime rates and stronger economies than comparable non-sanctuary cities.&quot; All references 2026-05-26.&lt;/ref&gt; 
* humans tortured by the US could sue the major media for suppressing honest discussion of the research that documents that torture is more likely counterproductive? An important report of the efficacy of torture was published in 1631 by [[w:Friedrich Spee|Friedrich Spee]], a German Jesuit priest and professor. A few years earlier, the Duke of Brunswick had invited Spee and another famous Jesuit scholar to supervise a continuation of the torture of a confessed witch. The Jesuits had previously told the Duke, &quot;The Inquisitors are doing their duty. They are arresting only people who have been implicated by the confession of other witches.&quot; The Duke then led the Jesuits to a woman being stretched on the rack and asked her, &quot;You are a confessed witch. I suspect these two men of being warlocks. What do you say? Another turn of the rack, executioners.&quot; &quot;No, no!&quot; screamed the woman. &quot;You are quite right. I have often seen .. . They can turn themselves into goats, wolves ... Several witches have had children by them. ... The children had heads like toads and legs like spiders.&quot;&lt;ref&gt;Pinker (2011, pp. 138-139). Mannix (1964, pp. 134-135). Mackay ( 2009, p. 320).&lt;/ref&gt; Crudely similar comments about the counterproductive nature of torture were made by Generals [[w:Stanley McChrystal|Stanley McChrystal]] (2013) and [[w:David Petraeus|David Petraeus]],&lt;ref&gt;DePaulo (2008).&lt;/ref&gt; who held command positions in Iraq and Afghanistan. The major media in the US has provided ample coverage of, e.g., comments by Donald Trump supporting torture (McCarthy 2016), while largely suppressing honest discussion of the research on it. 

Might the world be safer and more prosperous if major media outlets and their executives and journalists could be successfully sued when their biased reporting have substantive negative consequences? Might [[w:Freedom of information|the public's right to receive diverse information]] be advanced in this way, recognizing that false information disseminated by major media outlets can lead to substantive harms, similar to &quot;[[w:Shouting fire in a crowded theater|shouting ''fire'' in a crowded theater]]&quot;, while the same information disseminated by minor outlets would ''not'' produce such harms? 

Lawsuits of this nature could be facilitated by &quot;group libel&quot; laws. Activists were working to pass such laws in the 1940s. By 1950 those campaigns had been abandoned, according to Barbas (2023).&lt;ref&gt;See also Calvert et al. (2023, pp. 178ff).&lt;/ref&gt; 

[[w:Yael Eisenstat|Yaël Eisenstat]] agrees that under [[w:Section 230|Section 230]] of Title 47 of the US Code, &quot;No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider.&quot; However, Eisenstat insists that [[Online platforms' effects on public health, safety and democracy|&quot;an interactive computer service&quot; ''can'' be held liable when their algorithms have substantive negative consequences]], as in the jury verdicts against Meta in New Mexico&lt;ref&gt;Allyn (2026).&lt;/ref&gt; and against Meta and Google in Los Angeles.&lt;ref&gt;McQue (2026).&lt;/ref&gt; She said, &quot;those technologies, if they are, in the end, contributing to an illegal activity or to harm, that's what we should be addressing. ... The ultimate goal is not to shut down every social media company. The ultimate goal is to figure out what a safer online experience looks like and what accountability looks like when something unsafe happens.&quot;

You, dear reader, can help overcome these problems by talking, as suggested in the exercises below and the rest of this book. If you can help others become less angry and more willing to agree to disagree agreeably with others, that should reduce the risk of war and improve the prospects for progress on other major problems facing humanity today. 

==2. Training in nonviolent noncooperation for anyone willing to listen == 

A major driver of the current conflict between India and Pakistan is mistreatment of Muslims in India. Simulations of a nuclear war between India and Pakistan suggest that such a war would likely produce a nuclear autumn lasting years during which 40 percent of humanity would starve to death if they did not die of something else sooner. Over 90 percent of those would be in countries not involved in the nuclear exchange.&lt;ref&gt;Xia et al. (2022). See also Wikiversity, &quot;[[Responding to a nuclear attack]]&quot;, accessed 2026-05-05.&lt;/ref&gt;

The recent &quot;[[w:2025 India–Pakistan conflict|2025 India–Pakistan conflict]]&quot; was a response by India to violence in Indian-administered [[w:Kashmir|Kashmir]] by terrorists allegedly supported by Pakistan. India would have had much more difficulty justifying violent repression of ''nonviolent'' protests, especially if a more diverse media ecology gave such protests more and more sympathetic coverage. 

During the [[w:Great Depression|Great Depression]], ethnic Germans in the [[w:Sudetenland|Sudetenland]] region of [[w:Czechoslovakia|Czechoslovakia]] were harder hit by increasing trade barriers than their non-German neighbors. They were therefore more open to populist and extremist movements such as fascism, communism and German irredentism.&lt;ref&gt;Wikipedia, &quot;[[w:Sudetenland|Sudetenland]]&quot;, esp. the section on &quot;[[w: Sudetenland#Within the Czechoslovak Republic (1918–1938)|Within the Czechoslovak Republic (1918–1938)]]&quot;, accessed 2026-05-05.&lt;/ref&gt; If those ethnic Germans had used nonviolent noncooperation to highlight their grievances, and if Czechoslovakia at that time had had a substantially more diverse media system, it seems likely that they could have gotten reasonable redress of grievances. If so, it would have been harder for Hitler to use that as an excuse to invade Czechoslovakia, as he did in 1938.&lt;ref&gt;Wikipedia, &quot;[[w:Occupation of Czechoslovakia (1938–1945)|Occupation of Czechoslovakia (1938–1945)]]&quot;, accessed 2026-05-05.&lt;/ref&gt; 

In 1940, during World War II, Germany invade Denmark, which had previously declared neutrality. The Germans allowed [[w:1943 Danish Folketing election|Danish parliamentary elections in 1943]]; the Danish Nazi party won on 2.1% of the votes.&lt;ref&gt;{{cite web|title=Rigsdagsvalgene i Marts og April 1943|url=http://www.dst.dk/pukora/epub/upload/20217/valg1943.pdf|date=|publisher=Danmarks Statistic|accessdate=11 February 2021}}&lt;/ref&gt; When the Nazis ordered the Danes [[w:Rescue of the Danish Jews|to ship their Jews to the death camps, the Danes ignored those orders.]] When the Germans decided to do it themselves, a German diplomat leaked that decision, and nearly all Danish Jews escaped to neutral Sweden; 99% of Denmark's Jewish population survived the Holocaust.

An ideal settlement of the current Russo-Ukraine war might include training in nonviolent noncooperation made more effective through a more diverse media culture as suggested above. A substantial portion of the Ukrainian population, especially the Ukrainian military, are reported to be vicious anti-Russian Nazis, and the Ukrainian government has outlawed many uses of non-Ukrainian languages, especially Russian.&lt;ref&gt;Horton (2024).&lt;/ref&gt; A campaign of nonviolent noncooperation with a vigorous, diverse adversarial press would likely make it harder for Ukraine to continue any persecution of Russian speakers. It would also make it harder for major media in the US and Western Europe to suppress honest discussion of anti-Russian racism in Ukraine. Swanson (2022) said that the [[w:Baltic states|Baltic states]] have implemented such training in preparations for a possible Russian invasion; they might be asked to support such training in Ukraine (and elsewhere).&lt;ref&gt;Swanson (2022).&lt;/ref&gt; 

Organizations offering training in [[w:Nonviolent resistance|nonviolent noncooperation]] include [[w:Nonviolence International|Nonviolence International]] and the [[w:Highlander Research and Education Center|Highlander Research and Education Center]]. 

=== Civil resistance deters fracking ===

Duhamel (2013) claimed that well-advertised planning and training in nonviolent noncooperation helped deter oil companies from attempting hydraulic fracturing in [[w:Quebec|Quebec Province]] in [[w:Canada|Canada]]. Deterring a foreign invasion is different, but the same principle should apply: It's clear from many sources that elites consider nonviolence a threat; it's a felony to teach nonviolence to someone whom the US State Department claims supports a &quot;foreign terrorist organization&quot;, discussed in the next section.  

=== Life in prison for teaching nonviolence ===

Per the US Supreme Court decision in ''[[w:Holder v. Humanitarian Law Project|Holder v. Humanitarian Law Project]]'' (2010), teaching nonviolence to anyone whom the US State Department claims supports a foreign terrorist organization is &quot;[[w:Providing material support for terrorism|providing material support for terrorism]]&quot;, which is a felony under the USA [[w:Patriot Act|Patriot Act]] of 2001. Moreover, if the State Department claims that the death of any &quot;person&quot; resulted from the activities of the designated foreign terrorist organization, the penalty can be life in prison, where &quot;person&quot; is defined in the Patriot Act as &quot;any individual or entity capable of holding a legal or beneficial interest in property&quot;.&lt;ref&gt;The treatment of [[w:Sami Al-Arian|Sami Al-Arian]] is worth noting in discussing the Patriot Act. Al-Arian is a Kuwaiti-born political activist of Palestinian origin, who earned a doctorate in Electrical Sciences and Systems Engineering at [[w:North Carolina State University|North Carolina State]] in 1985 and taught computer engineering at [[w:University of South Florida|University of South Florida]] (USF) beginning in 1986. He was granted permanent resident status in 1989. In 1993 he earned a Distinguished Teacher Award as a tenured associate professor at USF. He was an [[w:imam|imam]] in a local [[w:mosque|mosque]] and led in other initiatives to promote dialogue and public policy initiatives between the West and Middle East. On September 26, 2001, he appeared on ''[[w:The O'Reilly Factor|The O'Reilly Factor]]'' where he was confronted with a 1988 recording of him shouting &quot;death to Israel&quot;. Al-Arian replied that &quot;Death to Israel&quot; meant &quot;death to occupation, ... apartheid, ...oppression,&quot; whereupon O'Reilly cut him off and called for the [[w:Central Intelligence Agency|Central Intelligence Agency]] to investigate him. Al-Arian spent most of the next 14 years between that 2001 interview and 2015 in detention, much of it in solitary confinement. This period included a 2005 trial that ended with acquittal on 8 counts and a hung jury on another 9. In 2015 he was deported to Turkey. In 2017, he founded the Center for Islam and Global Affairs at [[w:Istanbul Sabahattin Zaim University|Istanbul Sabahattin Zaim University]] in Istanbul, Turkey, which he directs. What has been the impact of treatment of Al-Arian on the well-being of the bottom 99 percent of the US and world population?&lt;/ref&gt; 

How did these provisions get written into the Patriot Act? 

That's a question that deserves research, perhaps by asking elected officials in the US Congress and lobbying for their repeal. A speculation consistent with the thesis of this book is that nonviolence terrifies those who control most of they money for the media, because it threatens their ability to get their security forces to follow orders.

==3. Forbid uses of force beyond one’s own borders and covert interference in foreign countries ==

:''[[w:Si vis pacem, para bellum|If you want peace, prepare for war.]]''
:  -- ''[[w:De Re Militari|De Re Militari]]'' by [[w:Publius Flavius Vegetius Renatus|Publius Flavius Vegetius Renatus]] (fourth or fifth century AD)

The record of history is now clear: Those who prepared for war often got war initiated when one party claimed they were being attacked or about to be attacked and believed they would fare better by attacking. Sometimes this occurred when the media environment convinced leaders that their political futures required them to clandestinely provoke foreign entities to do things that could then be denounced as unprovoked to justify military escalation, as mentioned in the previous section.  

Samuelson (2025) summarized quantitative analyses of 60 insurgencies since World War II, whose findings included the complete absence of success with counterinsurgencies without large force ratios (at least four, and most often more than ten, times the force of the insurgents) and without &quot;providing a path toward peaceful addressing of grievances&quot;. He also noted that, &quot;Brutality toward the civilian population ... tends to inflame the insurgency.&quot;&lt;ref&gt;Samuelson (2025) summarized Lawrence (2015).&lt;/ref&gt; His analysis gave a pessimistic prognosis for the [[w:Gaza war|Gaza war]] that began 2023-10-07. His conclusions are consistent with the history of the current [[w:Russo-Ukrainian war|Russo-Ukrainian war]], the [[w:Vietnam War|Vietnam War]], the [[w:Graveyard of empires|First, Second, and Third Anglo-Afghan Wars (1839-1919), the Soviet-Afghan War (1979–1989), the US-led War in Afghanistan (2001–2021)]], the 2001-2011 [[w:Iraq War|Iraq War]], and others. 

A key point is that invaders often to lose unless they enter with overwhelming force like Germany in the early stages of World War II: The [[w:Occupation of Czechoslovakia (1938–1945)|Czechoslovaks]], [[w:Invasion of Poland|Poles]], [[w:France during World War II|French]], and others were not prepared to fight the Germans, but the [[w:Soviet Union in World War II|Soviets]] were. [[w:Adolf Hitler|Hitler]] doubtless knew that the [[w:Switzerland during World War I and World War II|Swiss]] were prepared to fight, so he attacked other countries first. While fighting the [[w:Russo-Ukrainian war#Full-scale Russian invasion of Ukraine (2022)|Russian invasion]] that began 2022-02-24, [[w:Defense industry of Ukraine|Ukraine has developed]] military drones that are highly effective relative to the cost, as witnessed by sales of such to Gulf Arab states,&lt;ref&gt;Sharawi and Shapiro (2026).&lt;/ref&gt; illustrating the point that foreign invaders often encounter vastly more resistance than they expect -- and should expect highly effective resistance if they invade a country prepared to fight on their own territory. 

The rest of this section discusses weaknesses with standard deterrence theory. 

===Deterrence theory and nuclear Armageddon=== 

Standard [[w:Deterrence theory|deterrence theory]] assumes that one's opponents are rational and do not want [[w:Armageddon|Armageddon]]. The record of history summarized above raises questions about this assumption: In World War I, even the &quot;winners&quot; arguably lost more than they gained -- doubtless excepting a few merchants, who made fortunes from what they sold. Many of the other military decisions discussed above seem to have been driven more by the media than military necessity. 

Beyond that, at least some portions of the [[w:Islamic State|Islamic State]] reportedly violates this assumption, because it &quot;not only believes in the literal meaning of the coming Armageddon – it sees itself as its chief protagonist.&quot;&lt;ref&gt;Misra (2015).&lt;/ref&gt; Some [[w:Christian nationalism|Christian nationalists]] promoted to command positions by [[w:United States Secretary of Defense|US Secretary of Defense]] [[w:Pete Hegseth|Hegseth]] and President Trump also seem to believe that Armageddon might be desirable. On 2026-03-03 the [[w:Military Religious Freedom Foundation|Military Religious Freedom Foundation]] said they had received over 200 complaints from over 50 different US military installations with comments like, &quot;President Trump has been anointed by Jesus to light the signal fire in Iran to cause Armageddon and mark his return to Earth&quot;, per an email from one [[w:Non-commissioned officer|NCO]].&lt;ref&gt;Nick Mordowanec (2026).&lt;/ref&gt; With Hegseth holding monthly Christian worship services in the Pentagon during business hours,&lt;ref&gt;Black (2025), Mayes-Osterman (2025). See also the section on &quot;[[w:Pete Hegseth#Pentagon Christian worship services and &quot;biblically sanctioned war&quot;|Pentagon Christian worship services and &quot;biblically sanctioned war&quot;]] in the Wikipedia article on [[w:Pete Hegseth|Pete Hegseth]], accessed 2026-05-14.&lt;/ref&gt; this suggests that Hegseth could have appointed enough Christian nationalists to key positions to initiate nuclear attacks on Iran or Russia, claiming that President Trump had ordered such whether he had or not.&lt;ref&gt;The [[w:Gold Codes|Gold Codes]] carried in the &quot;[[w:nuclear football|nuclear football]]&quot; required by the [[w:Permissive action link|permissive action link]]s would ''not'' prevent Hegseth and a few others appointed by him from initiating nuclear Armageddon, according to Ellsberg, who had been a nuclear war planner for presidents Eisenhower, Kennedy, Johnson, and Nixon, before releasing the ''[[w:Pentagon Papers|Pentagon Papers]]''. Ellsberg (2017, p. 69) insisted that the security provided by those Gold Codes were a hoax, because otherwise a single nuclear detonation on Washington, DC, when both the president and vice president were in town &quot;would would definitively block any authorized, coordinated nuclear response to that or any subsequent nuclear attack.&quot;&lt;/ref&gt; 

The biggest risk today may be the risk of [[w:Nuclear holocaust|nuclear Armageddon]], which seems on average to grow over time consistent with experience with &quot;[[w:system accidents|system accidents]]&quot; in other fields: It is naive to assume that any system as complex as military command, control and communications systems never fail. And managers of complex systems subject to rare, catastrophic failures &quot;learn&quot; from experience that they can take ever greater risks, because they have &quot;safely&quot; done so in the past — until there is a catastrophe:&lt;ref&gt;Kahneman and Klein (2009) found that expert intuition, when it exists, is learned from frequent, rapid, high quality feedback. With anything nuclear, mishaps are so rare that managers develop &quot;expert intuition&quot; that they can &quot;safely&quot; ignore safety concerns -- until there is a catastrophe. See also Sagan (1993).&lt;/ref&gt; 

Veterans for Peace (2022) recommend global reduction and rapid elimination of nuclear weapons &quot;to reduce the real risk of nuclear confrontation through accidental launch or miscalculated escalation&quot;. 

==== National security tariffs ====

Free trade agreements supported by the [[w:World Trade Organization|World Trade Organization]] allow exemptions for national security and other objectives. [[Responding to a nuclear attack|Even a minor nuclear war between India and Pakistan would have a negative impact on the entirety of humanity]]. It might therefore be sensible for parties to the [[w:Treaty on the Prohibition of Nuclear Weapons|Treaty on the Prohibition of Nuclear Weapons]] (TPNW) to institute gradually increasing tariffs on nuclear weapon states, not so great as to seriously impact the economy of the nation applying such tariffs but aggressive enough to gradually wean their economy from reliance on trade with nuclear-weapon states that refuse to support the TPNW. 

See also the chapter below on [[/Media Literacy and You/Responding to a nuclear attack/|Responding to a nuclear attack]]. 

===Research on the effectiveness of deterrence and implications=== 

Lebow and others have provided substantial documentation of case studies claiming that leaders are often not rational, and deterrence based on threatening use of military force beyond one’s own borders has been ''as likely to provoke as prevent'' undesired behavior.&lt;ref&gt;Lebow (2025, 2024), Lebow et al. (2023).&lt;/ref&gt; The most obvious portions of this threat can be entirely eliminated by policies clearly and effectively forbidding use of force beyond one’s own borders. This can be signaled in at least three ways: 

* Eliminate all weapon systems like missiles and aircraft with a range of more than, e.g., a hundred miles or 200 kilometers with the possible exception of surveillance only aircraft that cannot be easily configured to carry [[w:Materiel#Military|ordnance]], e.g., explosives. Similarly eliminate nuclear weapons, which few if any countries would want to use for military defense inside their own borders. 

* Supply a national guard and reserves with weapons, training, and rules of engagement that prohibit projecting force beyond one’s own borders. Train them also in development and use of improvised explosive devices and other tactics and devices like low cost military drones. 

:Afghanistan is said to be the &quot;[[w:Graveyard of empires|Graveyard of empires]]&quot;. They defeated the British three times (1839–1842, 1878–1880, 1919), the Soviet Union (1979–1989), and the US (2001–2021). Each victory came with foreign supplies, but any foreign troops helping Afghanis were primarily under the command of local leaders. 
:The [[w:2003 invasion of Iraq|2003 invasion of Iraq]] might have produced [[w:Nation-building|nation-building]] more like the experience of [[w:Nation-building#Germany and Japan after World War II|Germany and Japan after World War II]] if the US had mandated a vigorous adversarial press instead of strict censorship, according to McChesney and Nichols.&lt;ref&gt;McChesney and Nichols (2010, Appendix II. Ike, MacArthur and the Forging of Free and Independent Press, pp. 241-254).&lt;/ref&gt; This claim by McChesney and Nichols was not endorsed by [[News from Germany 1900-1945 and implications for today#After the war in Germany vs. Iraq|University of British Columbia History professor Heidi Tworek]], who said the democratization efforts in Germany and Japan after World War II were more complicated than that implied by that brief discussion by McChesney and Nichols.&lt;ref&gt;The 2025-07-03 interview with Tworek is available at &quot;[[News from Germany 1900-1945 and implications for today]]&quot;, accessed 2026-05-14.&lt;/ref&gt; However, the research by Usher and Kim-Leffingwell (2022) and the related research on news deserts summarized in the preface to this ''[[Media Literacy and You]]'' book largely supports those claims by McChesney and Nichols.
:[[w:Defense industry of Ukraine|Ukraine has become a world leader in military drones]], many of which are dramatically cheaper than alternatives. Most of those have limited range but have been useful for reconnaissance and delivery of ordnance and improving targeting of, e.g., surface to air missiles. 
:[[w:Eliot A. Cohen|Eliot Cohen]], who served as a special advisor to [[w:United States Secretary of State|US Secretary of State]] [[w:Condoleezza Rice|Condoleezza Rice]] from 2007 to 2009, wrote, &quot;As the United States discovered in Iraq and Afghanistan, no matter how large, technologically advanced, and proficient an army is, motivated insurgents can still inflict casualties in the tens of thousands.&quot;&lt;ref&gt;Cohen (2022), cited from Horton (2024, p. 1026).&lt;/ref&gt; Cohen recommended we &quot;Arm the Ukranians now&quot;. Horton said that the neoconservatives learned from Iraq War II and Afghanistan that the US &quot;should fight like those who defeated them.&quot;&lt;ref&gt;Horton (2024, p. 1026).&lt;/ref&gt; 
:Leading economist [[w:Jeffrey Sachs|Jeffrey Sachs]] addressed the European Parliament 2025-02-19, claiming that the tragedy that befell Serbia in 1999 and subsequent US uses of force in Iraq and Syria, plus wars in Africa including Syria, Somalia and Libya and the current wars in Ukraine and the Israel-Hamas war, &quot;are to a very significant extent the result of deeply misguided US policies.&quot;&lt;ref&gt;Sachs (2025-02).&lt;/ref&gt; He said that Europe should craft its own foreign and military policies, independent of the US. ''[[w:Le Monde Diplomatique|Le Monde Diplomatique]]'' noted that Sachs' speech has circulated among social media since ''but has yet to be seriously discussed by major European media.''&lt;ref&gt;Sachs (2025-04; emphasis added).&lt;/ref&gt; 

* Change the laws of government secrecy so government officials cannot secretly interfere in the internal affairs of foreign countries or otherwise project force outside their own borders. This might be achieved in the US in part by requiring anyone with information about questionable actions by government officials to provide such documentation to one or more congressional oversight bodies while also allowing any current or former government employee or contractor to file suit in any US federal jurisdiction if they feel they have been punished for refusing to support questionable activities. In addition, federal judges should be authorized to subpoena classified government documents that may be relevant to any case in their jurisdiction and declassify them subject to appellate review if they believe the national interest would be better served by declassification. 

:If the law is changed without a substantive [[#1. Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content.|citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference]], as discussed above, the change could be merely cosmetic and unconvincing to local public officials and potential adversaries. 
:Connelly (2023) noted that US government secrecy has in the past encouraged administration officials to do things to provoke actions by foreign entities that can then be denounced as “unprovoked” to stampede the US Congress and the public into supporting counterproductive uses of military force, as discussed above.&lt;ref&gt;See also Connelly et al. (2023).&lt;/ref&gt; A more diverse media culture should make it harder for administration officials to lie to the public and to Congress — and harder to punish government employees who tell their managers that they should not lie to Congress, as they reportedly did to [[#Richard Barlow and nuclear proliferation|Richard Barlow]], mentioned above. 
:The Barlow case and many others explain why the US should, e.g., give federal judges the authority to subpoena classified documents and declassify them if they believe the public good is better served from declassification than continued secrecy.&lt;ref&gt;See, e.g., the 2025-05-08 interview with Seth Stern and Lauren Harper discussing what the &quot;[[Freedom of the Press Foundation says...]]&quot;, Graves (2014), and [[w:Moynihan Commission on Government Secrecy|Moynihan Commission on Government Secrecy]], accessed 2026-05-06. Graves (2021) recommends &quot;Congressional Gold Medals for&quot; Barlow and whistleblowers.&lt;/ref&gt; 

These policies would make it hard for any foreign leader to justify an attack for multiple reasons: First, it would be difficult to convince their supporters that such an attack is necessary. Second, a rational foreign leader might be hesitant to invade a country that is prepared to fight a guerrilla war. Germany reportedly considered invading [[w:Switzerland during World War I and World War II|Switzerland during both World Wars I and II]] and decided against it in part because Switzerland had large, well-trained ready reserves, who were ready to fight. Belgium seemed to be an easier route.&lt;ref&gt;Documented in Wikipedia, &quot;[[w:Switzerland during World War I and World War II|Switzerland during World War I and World War II]]&quot;, accessed 2026-05-06. Switzerland also has many mountains, which make it easier to defend, but the capabilities of the Swiss military also influenced the German decision to avoid Switzerland.&lt;/ref&gt; Third, even if foreign invaders defeat the guerrillas, they should not assume that their invading forces would continue to follow orders. [[w:Rescue of the Danish Jews|Ninety-nine percent of Danish Jews reportedly survived World War II]] because of Danish noncooperation ''supported by a German diplomat''.&lt;ref&gt;Wikipedia, &quot;[[w:Rescue of the Danish Jews|Rescue of the Danish Jews]]&quot;, accessed 2026-05-06.&lt;/ref&gt; 

With policies like these in place, it would be hard for foreign leaders to convince their supporters of a need to attack, as [[w:2022 Russian invasion of Ukraine|Putin did when invading Ukraine in 2022]],&lt;ref&gt;The Wikipedia article on &quot;[[w:2022 Russian invasion of Ukraine|2022 Russian invasion of Ukraine]]&quot;, accessed 2026-05-06, includes a paragraph saying, 'In July 2021, Putin published an essay &quot;On the Historical Unity of Russians and Ukrainians&quot;, in which he called Ukraine &quot;historically Russian lands&quot; and claimed there is &quot;no historical basis&quot; for the &quot;idea of Ukrainian people as a nation separate from the Russians&quot;'. Putin was accused of promoting Russian imperialism, historical revisionism and disinformation. Writing in 2024, Michael McFaul and Robert Person described this essay as representing not only &quot;cynical propaganda&quot; but also Putin's &quot;deeply held and internalized beliefs&quot;. See the Wikipedia article for references supporting those claims.&lt;/ref&gt; as [[w:2025 India–Pakistan crisis|India did when attacking Pakistan in 2025]], and as [[w:Invasion of Poland|Hitler did when invading Poland in 1939]], to name only three examples. 

=== If we continue to base deterrence on threats === 

There are now calls for Europe to get their own nuclear weapons,&lt;ref&gt;Burgard (2025).&lt;/ref&gt; while Iran, Saudi Arabia, Turkey, South Korea and Taiwan have been suggested as other candidates for acquiring nuclear weapons should they feel a sufficient need.&lt;ref&gt;Ruehl (2024).&lt;/ref&gt; 

It is difficult to imagine how the number of nuclear weapon states could be increased without increasing the risks of a nuclear war, consistent with the discussion of &quot;[[w:system accident|system accident]]s&quot; earlier in this chapter.

Secondarily, intelligence services with information on political corruption including attempts to intimidate and murder journalists should not be allowed to keep that information secret: They should be required to find ways to leak that information to journalists. Such attacks on journalists in their own country should be exposed and prosecuted if the evidence seems likely to obtain a conviction. Intelligence services with information about such attacks in other countries should be required to find ways to leak it to competent journalists without identifying their sources and methods: Doing so would likely reduce political corruption worldwide and with that the risks of war. 

== Collateral damage ==

The research cited above supports the claim that, 

:''[[w:Collateral damage|Collateral damage]] that our designated enemies commit prove to us that they are subhuman or criminally misled.''
:''Meanwhile, collateral damage that we commit is unfortunate but necessary -- from our perspective. However, it proves to our designated enemies that we are subhuman or criminally misled.'' 

This observation supports this entire program of deterrence without threat: 
* Forbidding use of force beyond one’s own borders and covert interference in foreign countries would automatically reduce collateral damage. It would also avoid uses of force that seem not to contribute to broadly shared peace and prosperity, according to research cited above. 
* The effectiveness of nonviolent noncooperation rests in part on its near universal avoidance of collateral damage. 
* Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content should make it much harder for major media to convince the public to do things contrary to their best interests, like invading or interfering covertly in foreign countries. 

== Call for help == 

Do you, dear reader, know other serious research not cited herein that might improve this analysis? If yes, you can help improve this discussion by adding comments with citations -- or by adding such citation(s) to the &quot;Discuss&quot; page associated with this chapter, suggesting someone else revise the chapter appropriately. 

There are plenty of contrary claims in the major media, but the lead author of this chapter is not aware of any that are based on serious research. 

In the absence of such research, the current author finds it difficult to imagine any national defense policies that carry a greater risk of nuclear Armageddon than our current policies, as discussed in the next chapter of this book on ''[[Media Literacy and You]]'' on &quot;[[Media Literacy and You/Responding to a nuclear attack|Responding to a nuclear attack]]&quot;. That chapter, in sum, claims that the ''worst'' response to a nuclear attack would be nuclear response, because it would escalate a catastrophe killing millions of humans to one killing ''billions'', possibly 80 percent of humanity in a war between the US and Russia that lofts so much smoke from burning cities to the stratosphere where it covers the globe depressing crop yields for years during with 99 percent of the humans in the US, Europe and Russia would starve to death if they did not die of something else sooner. Moreover, the record of &quot;[[w:System accident|system accident]]s&quot; suggests that the chances of such a war before the end of this century is substantially greater than the 40 percent median estimate based on history mentioned in a presentation on &quot;[[Time to nuclear Armageddon]]&quot; delivered to the 2019 Joint Statistical Meetings. 

This chapter is being written in the hopes of inspiring action to improve the prospects for broadly shared peace and prosperity for the long term. 

== Exercises ==

1. Disconfirmation bias: Brainstorm your biggest concerns about a current or possible future war. 
:1.1. Select the one that is of greatest concern to you currently. 
::One issue that may not be a major concern for many but might elicit a broad consensus for action would be a campaign to ask elected officials in the US Congress to explain how we benefit from the provisions of the USA Patriot Act of 2001 that authorize [[#life in prison for teaching nonviolence|life in prison for teaching nonviolence]]. 
:1.2. Who are your designated enemies? 
:1.3. Research what your designated enemies are saying about your biggest concern.  
:1.4. Under what circumstances would you support what you see your designated enemies advocating or doing? 
::If you cannot see such circumstances, expand your research: Look for more sources that support your designated enemies. 

2. Interacting: Ask others if you can share what you've learned about that conflict. If they say, &quot;No&quot;, don't push it. If they agree, share what you've learned in a friendly supportive manner without saying that anything is &quot;true&quot;. 

::''Show me someone who knows the truth, and I will show you someone who is dangerous.''

:2.1. The primary goal in this is ''not'' to convince anyone that you are right and they are wrong but to lower the level of anger and increase the level of tolerance for dissenting views. 
:2.2. Another goal is to comfortably enjoy civil conversations of this nature, agreeing to disagree agreeably and building trusting relationships that support collaboration on issues of common concern. 
:2.3. After becoming adept at building collaborations on issues of common concern, you might consider teaching this important skill and approach to issues.  

3. Teaching: Each one teach two, as discussed in the section on &quot;[[Media Literacy and You#Text and self-help book and point of discuss|Text and self-help book and point of discuss]]&quot; in the preface to this book.

:''Humanity is one misunderstanding, one miscalculation away from nuclear annihilation. ... This is madness. We must reverse course.''
:  -- [[w:António Guterres|UN Secretary General António Guterres]]  (2022)&lt;ref&gt;Jacobsen (2024), BBC (2022).&lt;/ref&gt;

:This book is a combination instruction manual on [[w:Media literacy|media literacy]] and an invitation to you to support collaborative / crowd-sourced research on how to improve the world's understanding of media literacy and how to accelerate its understanding and use globally for the betterment of humanity. 

Part I of this book on ''[[Media Literacy and You]]'' discusses &quot;The media and political economy&quot;. Except in times of terror, massive lawlessness or war, most humans place a high priority on their financial situation, the primary focus of Part I. Part II on &quot;The media and war&quot; focuses on security concerns starting with this chapter on &quot;Deterrence without threat&quot;. 

== Introduction ==

Every individual and group has a right and an obligation to defend itself. Unfortunately, when most humans&lt;ref&gt;We distinguish here between &quot;humans&quot; and &quot;people&quot; or &quot;persons&quot;, because under current US law, corporations are &quot;people&quot; and money is speech, per the US Supreme Court decision in ''[[w:Citizens United v. FEC|Citizens United v. FEC]]'' (2010) and many other judicial rulings and US law such as the [[w:Patriot Act|Patriot Act]] of 2001.&lt;/ref&gt; think of defense, they often think of violent responses to provocations. 

However, there is a growing body of research documenting 

:(a) how most uses of violence are counterproductive, and 
:(b) there are usually nonviolent options to violence that would more effectively promote broadly shared peace and prosperity for the long term. 

This research is rarely discussed by major media outlets, because it would offend the &quot;people&quot;&lt;ref&gt;We put &quot;people&quot; in quotes in this essay, because that term includes corporations under current US law.&lt;/ref&gt; who control most of the money for the media: Nonviolence threatens their ability to get compliance from security forces. As a result, many elites prefer to use force to the detriment of the bottom 99 percent of humanity. As discussed below, a military posture that supports projecting force beyond one’s own borders may be as likely to ''provoke'' as ''prevent'' an attack.&lt;ref&gt;For example, Lebow (2025) cites some of his previous work with others to support the claim that large militaries have been &quot;more provocative than preventative in&quot; their effects. And Lebow (2024) insists that, &quot;Policymakers respond more instinctively than analytically in deciding that some policy is or is not in the national interest.&quot; See also Lebow et al. (2023).&lt;/ref&gt; 

This chapter outlines a 3-part strategy that research suggests would more likely lead to better outcomes for the vast majority of humans: 

# Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content. 
# Training in nonviolent noncooperation for anyone willing to listen. 
# Forbid uses of force beyond one’s own borders and covert interference in foreign countries. 

We now discuss each of these briefly. 

== 1. Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content. == 

It seems that

:''Primary drivers of every major conflict include differences between the media that the different parties find crecible.''

In a recent interview with [[w:Fordham University|Fordham University]] Professor Emerita of Communications Robin Andersen,&lt;ref name=Andersen&gt;&lt;!--Robin Andersen--&gt;{{cite Q|Q132982358}}&lt;/ref&gt; she agreed with this claim and added: 

:''We only have enemies of our very own making.''

The media are involved in this, because:  

:''The major media create the stage upon which politicians read their lines.''&lt;ref&gt;In 1791 James Madison, who represented part of Virginia in the US House of Representatives 1789-1801 and later became the 4th President of the US (1809-1819), said, &quot;Public opinion sets bounds to every government, and is the real sovereign in every free one.&quot; Quoted from the ''[[w:National Gazette|National Gazette]]'' (published 1791-1793) by Schmeller (2009, p. 36) and Sauer (2016, p. 5). Sauer described how the American Revolutionaries, especially the first four US presidents, planted stories in newspapers to build support for how they dealt with the [[w:Barbary corsairs|Barbary pirates]], who were seizing merchant ships, raiding European coastal towns and villages, and selling European captives into slavery. The first two US presidents, [[w:George Washington|Washington]] and [[w:John Adams|Adams]], used that support for protecting US shipping and citizens by paying tribute to government leaders in Morocco, Algeria, Tunisia, and Libya. The next two presidents, [[w:Thomas Jefferson|Jefferson]] and [[w:James Madison|Madison]], convinced Congress to fund a navy and marines to fight the [[w:Barbary Wars|Barbary Wars]]. This included the [[w:Battle of Derna (1805)|Battle of Derna]]  (April-May 1805), memorialized in the [[w:Marines' Hymn|Marines' Hymn]], which mentions actions &quot;to the shores of Tripoli&quot;. Sauer described how the policies were sold to the public via planted stories in the different partisan newspapers.&lt;/ref&gt; 

This works because (a) virtually everyone thinks they know more than they do ([[w:Overconfidence effect|overconfidence effect]]), and (b) virtually everyone prefers information and sources consistent with preconceptions ([[w:confirmation bias|confirmation bias]]). 

Also, in many, perhaps all, countries, the primary constituency for foreign and military policy is the people with foreign business interests. Many of these people also control substantial portions of the money for the media, which have too often encourage questionable and counterproductive uses of military force.&lt;ref&gt;If we [[w:follow the money|follow the money]], we might find that &quot;watchdogs generally protect the people who feed them&quot;, as discussed in the 2025-09-25 interview with British journalist and media reform activist Dan Hind discussing how the British [[Media Reform Coalition challenges anti-democratic media bias in the UK]].&lt;/ref&gt; 

=== Examples === 

A leader in documenting the role of the media in armed conflict is Robin Andersen,&lt;ref&gt;e.g., Andersen (2006, 2026).&lt;/ref&gt; but she is not alone. For example, [[w:University of Denver|University of Denver]] journalism professor Kareem El Damanhoury&lt;ref name=Daman&gt;&lt;!--Kareem El Damanhoury--&gt;{{cite Q|Q113752441}}&lt;/ref&gt; has compared how [[w:Gaza Strip|Gaza]] has been framed differently by [[w:Al Jazeera Media Network|Al Jazeera]], the [[w:BBC|BBC]]&lt;ref&gt;El Damanhoury et al. (2025).&lt;/ref&gt; and [[w:Fox News|Fox]].&lt;ref&gt;El Damanhoury and Saleh (2024).&lt;/ref&gt;&lt;ref&gt;Some of El Damanhoury's work in this regard [[Differences between media outlets including coverage of Gaza|is reviewed in a 2025-11-20 interview with him]].&lt;/ref&gt; 

==== World War I ====

Andersen's (2006) ''A Century of Media, A Century of War'' begins with a discussion of &quot;The birth of war propaganda&quot; in &quot;The Great War and the Fight between Good and Evil&quot;.&lt;ref&gt;Andersen (2006, ch. 1)&lt;/ref&gt; 

A more detailed but compatible discussion of the media and [[w:World War I|World War I]] is given by [[w:John Maxwell Hamilton|John Maxwell Hamilton]]. Among other things, he said: {{quote|

The first iron law of propaganda is that only the enemy does it.&lt;ref&gt;Hamilton (2020, p. 642). See also the [[John Maxwell Hamilton on American propaganda|2025-12-11 interview with Hamilton]].&lt;/ref&gt;}} 

[[File:MB Walker - German bayoneting children - Life - July 25, 1915.png|thumb|left|Figure 1. Stories of German soldiers impaling children on their bayonets were widely reported during the war. However, no credible evidence was found to support these claims when questions were raised after the war.&lt;ref&gt;{{cite web|title=Alleged German atrocities: Bryce report|url=http://www.nationalarchives.gov.uk/pathways/firstworldwar/spotlights/p_alleged_german.htm|publisher=The National Archives|access-date=13 July 2014}}&lt;/ref&gt;]]

Andersen (2006, pp. 8-9) said, {{quote|

James Bryce, the former British ambassador to the United States, ... helped prepare a sixty-one page ''Report on the Committee on alleged German Outrages'', which was translated into thirty languages and was said to be based on twelve hundred depositions ... included gruesome and titillating details of how German soldiers publicly raped Belgian girls in the marketplace at Liege and bayonetted a two-year-old child. ... [A]fter the war a Belgian commission of inquiry found no evidence for any major accusation in the report. ...}}
{{quote|
German propagandists, on the other hand, ... &quot;bungled, because they were naïve: they thought the success of the war depended almost solely on military strategy and therefore they tended to neglect propaganda.&quot; ... Thus, when German soldiers shot some Allied nurses who had carried weapons, they admitted it openly. The Allies reported the incident as an atrocity and featured it in press propaganda. When French troops shot German nurses under similar circumstances, the Germans failed to exploit it.}} 

==== Jonathan Swift 1710 ====

This is not limited to World War I. In 1710, [[w:Jonathan Swift|Jonathan Swift]] reportedly said, &quot;Falsehood flies, and truth comes limping after ... like a physician, who hath found out an infallible medicine, after the patient is dead.&quot;&lt;ref name=Swift&gt;Excerpted from a line in [[Wikiquote:Jonathan Swift]] consulted 2026-04-13.&lt;/ref&gt;  

==== The Marines' Hymn ====

The [[w:Marines' Hymn|Marine Corps Hymn]] begins, {{quote|

From the Halls of Montezuma

To the shores of Tripoli;

We fight our country's battles

In the air, on land, and sea.}}

The &quot;[[w:Battle of Chapultepec|Halls of Montezuma]]&quot; refer to the [[w:Mexican–American War|Mexican–American War]], which was fought to expand slavery first into [[w:Texas|Texas]]  -- and supporters of slavery hoped that would help expand slavery further west. The &quot;[[w:Battle of Derna (1805)|shores of Tripoli]]&quot; were part of the [[w:Barbary Wars|Barbary Wars]], which were fought to reduce the need to pay (a) tribute to the [[w:Barbary Coast|Barbary or Berber]] states of [[w:Morocco|Morocco]], [[w:Algeria|Algeria]], [[w:Tunisia|Tunisia]], and [[w:Libya|Libya]] or (b) ransom to [[w:Barbary corsairs|Barbary pirates]], who were otherwise capturing Christians and selling them into slavery. 

Did the bottom 99 percent of the US population of that time benefit? Or did these wars (and any tribute and ransom paid by the US government before the Barbary wars) constitute a hidden transfer of wealth from the poor to the wealthy? 

A partial answer to this question is that [[w:tariff|tariff]]s on imported goods covered between 80 and 95 percent of all federal revenue up to 1860, and [[w:excise|excise taxes]] on only a few goods, such as whiskey, rum, tobacco, snuff and refined sugar, made up nearly all the rest.&lt;ref&gt;See the section on &quot;[[w:Excise tax in the United States#Historical background|Historical background]]&quot; in the Wikipedia article on &quot;[[w:Excise tax in the United States|Excise tax in the United States]]&quot;, accessed 2026-05-26.&lt;/ref&gt; The money raised from taxes on income during the Civil War, visible in Figure 3 above, were apparently negligible as a portion of federal revenue during the Barbary Wars and the Mexican-American War.  

==== Gulf of Tonkin Resolution: &quot;Betray the nation or do not get elected.&quot; ====

Regarding the [[w:Vietnam War|Vietnam War]], former president [[w:Dwight D. Eisenhower|Eisenhower]] wrote in his autobiography, which appeared in 1963 (he left the presidency 1961-01-20), that he had never communicated {{quote|

with a person knowledgeable in Indochinese affairs [including Vietnam] who did not agree that had elections been held as of the time of the fighting [leading to the defeat of the French in 1954], possibly 80 per cent of the population would have voted for the Communist [[w:Ho Chi Minh|Ho Chi Minh]].&lt;ref&gt;Eisenhower (1963, p. 372).&lt;/ref&gt;}}

[[w:Joseph McCarthy|Joseph McCarthy]], who had been elected to the US Senate in 1946 and &quot;experienced a meteoric rise in national profile beginning on February 9, 1950, when he gave a&quot; speech during which he said something like, &quot;The [[w:United States Secretary of State|State Department]] is infested with communists. I have here in my hand a list of 205—a list of names that were made known to the Secretary of State as being members of the Communist Party and who nevertheless are still working and shaping policy in the State Department.&quot; McCarthy's mostly baseless claims went largely unchallenged in the media, including accusing the Democrats of &quot;twenty years of treason&quot; for having been allied with the Soviet Union, which took the bulk of casualties during World War II. 

By the end of 1953 with (Republican) Eisenhower as president roughly 11 months, McCarthy was complaining about &quot;''21'' years of treason&quot;, complaining that Eisenhower was not sufficiently aggressive in rooting out the communists who McCarthy claimed were in the government.&lt;ref&gt;Fried (1997, p. 179).&lt;/ref&gt; 

Then the French were defeated by Vietnamese communists 1954-05-07 in the [[w:Battle of Dien Bien Phu|Battle of Dien Bien Phu]]. The [[w:1954 Geneva Conference|1954 Geneva Conference]], which had begun eleven days earlier, 1954-04-26, concluded 1954-07-21 with the &quot;Geneva Accords of 1954&quot;.&lt;ref&gt;The [[w:Battle of Dien Bien Phu|Battle of Dien Bien Phu]], 1954-05-07, effectively ended the [[w:First Indochina War|French Indochina War]]. This led to the [[w:1954 Geneva Conference|Geneva accords of 1954]], officially dated 1954-07-20 but actually signed the following morning. Those accords took effect on three different dates, July 27 and August 1 and 11 in three different sectors of Vietnam. See &lt;!--Agreement on the Cessation of Hostilities in Vietnam--&gt;{{cite Q|Q139676410}}&lt;/ref&gt; Those accords called for UN-supervised elections for July of 1956, when Eisenhower would presumably be campaigning for reelection. Eisenhower doubtless knew that he might lose his bid for re-election in 1956, if the Communist Ho Chi Minh won elections in July of that year. 

:''The consistent suppression of honest portrayal in the major media of that day of the perspective of anyone whom Eisenhower considered &quot;knowledgeable in Indochinese affairs&quot; gave him -- and his successors [[w:John F. Kennedy|Kennedy]], [[w:Lyndon B. Johnson|Johnson]], and [[w:Richard Nixon|Nixon]] -- the choice between betraying the nation or not getting elected.'' 

In this environment, the [[w:Operation 34A|US initiated a series of clandestine operations against North Vietnam]] including infiltrating CIA-recruited spies and supporting attacks against North Vietnam by South Vietnamese commandos.&lt;ref&gt;Paterson (2008).&lt;/ref&gt; This included a raid 1964-07-30 by South Vietnamese commandos on the island of Hòn Mê, roughly 300 km (180 miles) north of the [[w:Vietnamese Demilitarized Zone|Vietnamese Demilitarized Zone]] in the [[w:Gulf of Tonkin|Gulf of Tonkin]], covered by [[w:DESOTO patrol|US naval vessels]] patrolling in that area. Then during a dark and stormy night six days later, US naval vessels opened fire on radar snow, and President Johnson requested and received Congressional approval of the [[w:Gulf of Tonkin Resolution|Gulf of Tonkin Resolution]]; then-[[w:United States Secretary of Defense|US Secretary of Defense]] [[w:Robert McNamara|McNamara]] claimed those attacks were &quot;unprovoked&quot;.&lt;ref&gt;Karnow (1983, p. 375). See also the section on [[w:Gulf of Tonkin Resolution#Congress votes|Congress votes]]&quot; in the Wikipedia article on [[w:Gulf of Tonkin Resolution|Gulf of Tonkin Resolution]], accessed 2026-05-14.&lt;/ref&gt;

In this media environment, only two officials in the US Congress voted against the Gulf of Tonkin Resolution: [[w:Ernest Gruening|Ernest Gruening]] (D-AK) and [[w:Wayne Morse|Wayne Morse]] (D-OR). Gruening lost in his next primary campaign to [[w:Mike Gravel|Mike Gravel]], and Morse lost in his next general election campaign to [[w:Bob Packwood|Bob Packwood]]. These results support the previous claim that the major media give politicians the choice: 

:''Betray the nation, or do not get elected.''

That resolution became the primary authorization for the US war in Vietnam until Congress ended the funding. 

==== Was the Vietnam War lost in Washington or by media biases? ====

[[w:John Mueller|John Mueller]], prolific author, Professor Emeritus of international relations at [[w:Ohio State University|Ohio State University]] and Senior Fellow at the [[w:Cato Institute|Cato Institute]], said that the most effective thing the US did to win the [[w:Cold War|Cold War]] was —

:''nothing'': 

Between the [[w:Fall of Saigon|Fall of Saigon]] in 1975 and the inauguration of [[w:Ronald Reagan|Ronald Reagan]] as President of the US, the US &quot;went into a sort of containment funk: it effectively adopted a policy of complacency (or perhaps of appeasement) as it watched from the sidelines as the Soviet Union … opportunistically gathered a set of Third World countries into its imperial embrace: Angola in 1976, Mozambique and Ethiopia in 1977, South Yemen and Afghanistan in 1978, Grenada and Nicaragua in 1979.&quot;&lt;ref&gt;Mueller (2021,  p. 59).&lt;/ref&gt; Nearly all became major economic and political drains on the Soviets with Afghanistan being the worst. And their Warsaw Pact allies in Eastern Europe became a severe economic drain and psychic problem.&lt;ref&gt;Mueller and Graves (2023).&lt;/ref&gt; 

President Reagan, inaugurated 1981-01-20, had a very different vision of the role of the US in foreign relations from his predecessor, [[w:Jimmy Carter|Jimmy Carter]]. In 1983-06-21 Reagan insisted, &quot;We cannot permit the Soviet-Cuban-Nicaraguan axis to take over Central America&quot;, because the consequences would include &quot;a tidal wave of refugees ... 'feet people' ... swarming into our country.&quot;&lt;ref&gt;Clines (1983).&lt;/ref&gt; 

Other sources&lt;ref&gt;e.g., Andersen (2006, Part II).&lt;/ref&gt; insist the opposite, that the vast majority of deaths in Central America during the Reagan years were poor humans petitioning nonviolently for a redress of grievances, suppressed by terrorist / death squads supported by the Reagan administration largely in violation of laws passed by Congress and signed by President Reagan. On 1986-10-05 [[w:Corporate Air Services HPF821|a Nicaraguan soldier with a surface to air missile shot down a C-123]] cargo aircraft carrying supplies to the Contra roughly 35 miles (56 km) north of Costa Rica. Documents found in the wreckage and a confession by the sole survivor led to the [[w:Iran–Contra affair|Iran-Contra hearings]] the following year, during which Lt. Col. [[w:Oliver North|Oliver North]] insisted, &quot;We didn't lose the war in Vietnam ..., we lost it in this city.&quot;&lt;ref&gt;Andersen (2006, p. 137). See also, Wikipedia, &quot;[[w:Stab-in-the-back myth|Stab-in-the-back myth]]&quot;, accessed 2026-05-13.&lt;/ref&gt; 

The previous section on the &quot;Gulf of Tonkin Resolution&quot; provides an alternative narrative of the Vietnam War: If as Eisenhower claimed, &quot;possibly 80 per cent of the [Vietnamese] population would have voted for the Communist [[w:Ho Chi Minh|Ho Chi Minh]]&quot; if elections had been held there, it's hard to imagine how anyone else could have won without aggressive action that actually ''improved'' the lives of Vietnamese peasants in the South. US-led efforts there were officially designed to win &quot;[[w:Hearts and Minds (Vietnam War)|Hearts and Minds]]&quot; but were implemented with such coercion that the result was the opposite. A cynic might say that it is hard to win people's hearts and minds by killing them. 

====Richard Barlow and nuclear proliferation====

There is also documentation that the US helped Pakistan get nuclear weapons and destroyed the career of an intelligence analyst, [[w:Richard Barlow (intelligence analyst)|Richard Barlow]], for telling his managers they should not lie to Congress about it. Barlow has insisted that neither Pakistan nor North Korea would have nuclear weapons and Iran would not have a nuclear weapons program today, if the US had followed its own laws. Barlow’s claims, including his punishment by administration officials, have been reported in major media outlets&lt;ref&gt;e.g., Stein (2013). See also Wikipedia, &quot;[[w:Richard Barlow (intelligence analyst)|Richard Barlow (intelligence analyst)]]&quot;, accessed 2026-05-06.&lt;/ref&gt; but not in a way that would seriously limit the ability — and need — for administration officials to lie to Congress. 

If Barlow's claims are accurate, it suggests that US government officials violated US obligations under the [[w:Treaty on the Non-Proliferation of Nuclear Weapons|Non-Proliferation Treaty]] (NPT).&lt;ref&gt;Per the [[w:Treaty Clause|Treaty Clause]] of the US Constitution, a treaty negotiated by the President and approved by the Senate has &quot;the force of federal law.&quot;&lt;/ref&gt; 

==== Nayirah testimony and the 1990-1991 Gulf War ====

A more recent example is the 1990-10-10 testimony by [[w:Nayirah testimony|Nayirah al-Ṣabaḥ to the US Congressional Human Rights Caucus]], two months after the Iraqi invasion of Kuwait. She claimed to have seen Iraqi soldiers taking premature babies out of incubators in a maternity ward before looting the incubators and leaving the babies to die on the floor after the Iraqi invasion of Kuwait; she said she had been a volunteer nurse in the hospital at that time. 

The failure of journalists, including with the ''[[w:NBC Nightly News|NBC Nightly News]]'', to adequate check facts behind this and other atrocity stories helped convince the US public to support the US-led invasion of Iraq in 1990-1991. Nayirah's statements were widely publicized and cited numerous times in the United States Senate and by American president George H. W. Bush to contribute to the rationale for pursuing military action against Iraq. It was later revealed that she was the daughter of Kuwaiti ambassador to the US, [[w:Saud Nasser Al-Saud Al-Sabah|Saud Nasser Al-Saud Al-Sabah]], &quot;Reps. [[w:Tom Lantos|Tom Lantos]] and [[w:John Porter (Illinois politician)|John Edward Porter]], who sponsored the congressional hearings, had started a group called the Congressional Human Rights Foundation that had received $50,000 from Citizens for a Free Kuwait, as well as free office space in [[w:Hill &amp; Knowlton|Hill and Knowlton]]'s Washington headquarters&quot;,&lt;ref&gt;Rowse (1992).&lt;/ref&gt; and the public relations firm Hill and Knowlton had made a video while coaching her rehearsing her perjury and used that to prepare a video press release &quot;that eventually reached a total audience of about thirty-five million&quot;, 14 percent of the [[w:Demographic history of the United States|US population of 249 million per the census then in process]], with portions aired on the ''[[w:NBC Nightly News|NBC Nightly News]]'' the night after the testimony.&lt;ref&gt;Andersen (2006, pp. 170-171).&lt;/ref&gt; 

==== 1998 Embassy bombings and September 11 ====

As another example, there is substantial documentation available today that [[1998 Embassy bombings and September 11|the suicide mass murders of September 11, 2001]], likely would not have occurred if the US had treated the 1998 bombings of the US embassies in Kenya and Tanzania as law enforcement issues. Muslim clerics all over the world initially condemned those acts. Al-Qaeda was dead. Their funding had largely dried up. And bin Laden was scheduled to be extradited the following month to Saudi Arabia to be prosecuted for treason, where he would likely have been convicted and executed. Mayer (2008, p. 114) claimed those embassy bombings were motivated as retaliation for US support for torture.&lt;ref&gt;For more on torture, see the the section on [[#Make media responsible for harms|Make media responsible for harms]] below.&lt;/ref&gt; 

But it seemed questionable at best whether major media executives in the US would have given favorable coverage to such a diplomatic solution. Instead, the US bombed a pharmaceutical plant in Sudan and al-Qaeda training camps in Afghanistan. Then Muslim public opinion turned 180 degrees to conclude, &quot;Bin Laden is right: The US ''is'' an evil empire.&quot; The US became bin Laden’s only indispensable ally, according to the CIA agent responsible for tracking bin Laden at that time.&lt;ref&gt;Scheuer (2004, p. xv).&lt;/ref&gt; Leading Saudis started supporting al-Qaeda, including some working for the Saudi embassy and consulates in the US. Only one country seems to have been involved in the preparations for the September 11 attacks, and that was Saudi Arabia. But Saudis were friends of the Bush family, and a crisis is a terrible thing to waste.&lt;ref&gt;Romer (2009).&lt;/ref&gt; 

:''Did the US invade Afghanistan and Iraq on grounds that senior journalists and leading media executives should have known at the time were questionable and likely fraudulent — to the detriment of nearly everyone except the &quot;people&quot; who control most of the money for the media?'' 
:In particular, was Iraqi president [[w:Saddam Hussein|Saddam Hussein]] really a bigger threat to the US after he invaded Kuwait in 1990 or after the [[w:September 11 attacks|suicide mass murders of September 11, 2001]] than he was during the 1980s, when the US supported him [[w:Iran-Iraq War|killing Iranians]] or [[w:Anfal campaign|his own native Kurds]]? 

On 2003-05-29 [[w:BBC|BBC]] journalist [[w:Andrew Gilligan|Andrew Gilligan]] reported that the [[w:Tony Blaire|Blair government]] had &quot;sexed up&quot; [[w:September Dossier|intelligence reports]] issued the previous September to justify supporting the 2003-03-20 [[w:Iraq War|US-led invasion of Iraq]], two months before Gilligan's report. This led to the [[w:Hutton Inquiry|Hutton Inquiry]], which led to the resignations of Gilligan and the BBC's chairman and the firing of the BBC's director-general. However, the British public expressed so many reservations about the Hutton Inquiry that a follow-up investigation was ordered in 2009. This became the &quot;[[w:Iraq Inquiry|Iraq Inquiry]]&quot;, whose 2016-07-06 report essentially validated what Gilligan had said just over 13 years earlier. This provides one more example of the 1710 maxim of Jonathan Swift that, &quot;Falsehood flies, and truth comes limping after ... like a physician, who hath found out an infallible medicine, after the patient is dead.&quot;&lt;ref name=Swift/&gt;

====Ukraine war====

Page 1 of the 2023-05-04 edition of ''[[w:Le Monde Diplomatique|Le Monde Diplomatique]]'' carried a headline: 

:One year after the invasion of Ukraine: The media, vanguard of the war party,&lt;ref&gt;Halimi and Rimbert (2023) in the French-language original.&lt;/ref&gt;

consistent with Andersen (2006).

=== Make media responsible for harms ===

How might the world be different if injured parties could successfully sue major media for harms that result from government policies contradicted by evidence reasonably available to the major media outlets? 

For example, how might the world be different if: 

* combat veterans or their families could successfully sue major media outlets for biased reporting that stampede the nation into ill advised and counterproductive uses of military force on grounds that leading media personalities should have known at the time were questionable and likely fraudulent? 
* Vietnamese or Afghanis or Iraqis or Palestinians or victims in other countries could win similar lawsuits?
* immigrants could sue major media outlets for failing to publish reasonable summaries of the available research that says that immigrants on average are more entrepreneurial&lt;ref&gt;Aghion et al. (2022, pp. 266-270).&lt;/ref&gt; and no more likely to engage in criminal activities than native born, benefitting both the sending and receiving countries?&lt;ref&gt;The Wikipedia article on &quot;[[w:Immigration|Immigration]] cites research saying, &quot;that migration can be beneficial both to the receiving and sending countries. The academic literature provides mixed findings for the relationship between immigration and crime worldwide. ... [P]ublic perception often exaggerates the connection between immigration and crime, influenced by sensationalised media coverage and political rhetoric.&quot; The Wikipedia article on [[w:Immigration and crime|Immigration and crime]] notes that in some countries immigrants are over-represented in prison populations due to violations of immigration law or anti-immigrant biases in criminal justice. The Wikipedia article on &quot;[[w:Sanctuary city|Sanctuary city]]&quot; says that, &quot;Some studies on the relationship between sanctuary status and crime have found that sanctuary policies either have no effect on crime or that sanctuary cities have lower crime rates and stronger economies than comparable non-sanctuary cities.&quot; All references 2026-05-26.&lt;/ref&gt; 
* humans tortured by the US could sue the major media for suppressing honest discussion of the research that documents that torture is more likely counterproductive? An important report of the efficacy of torture was published in 1631 by [[w:Friedrich Spee|Friedrich Spee]], a German Jesuit priest and professor. A few years earlier, the Duke of Brunswick had invited Spee and another famous Jesuit scholar to supervise a continuation of the torture of a confessed witch. The Jesuits had previously told the Duke, &quot;The Inquisitors are doing their duty. They are arresting only people who have been implicated by the confession of other witches.&quot; The Duke then led the Jesuits to a woman being stretched on the rack and asked her, &quot;You are a confessed witch. I suspect these two men of being warlocks. What do you say? Another turn of the rack, executioners.&quot; &quot;No, no!&quot; screamed the woman. &quot;You are quite right. I have often seen .. . They can turn themselves into goats, wolves ... Several witches have had children by them. ... The children had heads like toads and legs like spiders.&quot;&lt;ref&gt;Pinker (2011, pp. 138-139). Mannix (1964, pp. 134-135). Mackay ( 2009, p. 320).&lt;/ref&gt; Crudely similar comments about the counterproductive nature of torture were made by Generals [[w:Stanley McChrystal|Stanley McChrystal]] (2013) and [[w:David Petraeus|David Petraeus]],&lt;ref&gt;DePaulo (2008).&lt;/ref&gt; who held command positions in Iraq and Afghanistan. The major media in the US has provided ample coverage of, e.g., comments by Donald Trump supporting torture (McCarthy 2016), while largely suppressing honest discussion of the research on it. 

Might the world be safer and more prosperous if major media outlets and their executives and journalists could be successfully sued when their biased reporting have substantive negative consequences? Might [[w:Freedom of information|the public's right to receive diverse information]] be advanced in this way, recognizing that false information disseminated by major media outlets can lead to substantive harms, similar to &quot;[[w:Shouting fire in a crowded theater|shouting ''fire'' in a crowded theater]]&quot;, while the same information disseminated by minor outlets would ''not'' produce such harms? 

Lawsuits of this nature could be facilitated by &quot;group libel&quot; laws. Activists were working to pass such laws in the 1940s. By 1950 those campaigns had been abandoned, according to Barbas (2023).&lt;ref&gt;See also Calvert et al. (2023, pp. 178ff).&lt;/ref&gt; 

[[w:Yael Eisenstat|Yaël Eisenstat]] agrees that under [[w:Section 230|Section 230]] of Title 47 of the US Code, &quot;No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider.&quot; However, Eisenstat insists that [[Online platforms' effects on public health, safety and democracy|&quot;an interactive computer service&quot; ''can'' be held liable when their algorithms have substantive negative consequences]], as in the jury verdicts against Meta in New Mexico&lt;ref&gt;Allyn (2026).&lt;/ref&gt; and against Meta and Google in Los Angeles.&lt;ref&gt;McQue (2026).&lt;/ref&gt; She said, &quot;those technologies, if they are, in the end, contributing to an illegal activity or to harm, that's what we should be addressing. ... The ultimate goal is not to shut down every social media company. The ultimate goal is to figure out what a safer online experience looks like and what accountability looks like when something unsafe happens.&quot; 

=== in sum ===

You, dear reader, can help overcome these problems by talking, as suggested in the exercises below and the rest of this book. If you can help others become less angry and more willing to agree to disagree agreeably with others, that should reduce the risk of war and improve the prospects for progress on other major problems facing humanity today. 

==2. Training in nonviolent noncooperation for anyone willing to listen == 

A major driver of the current conflict between India and Pakistan is mistreatment of Muslims in India. Simulations of a nuclear war between India and Pakistan suggest that such a war would likely produce a nuclear autumn lasting years during which 40 percent of humanity would starve to death if they did not die of something else sooner. Over 90 percent of those would be in countries not involved in the nuclear exchange.&lt;ref&gt;Xia et al. (2022). See also Wikiversity, &quot;[[Responding to a nuclear attack]]&quot;, accessed 2026-05-05.&lt;/ref&gt;

The recent &quot;[[w:2025 India–Pakistan conflict|2025 India–Pakistan conflict]]&quot; was a response by India to violence in Indian-administered [[w:Kashmir|Kashmir]] by terrorists allegedly supported by Pakistan. India would have had much more difficulty justifying violent repression of ''nonviolent'' protests, especially if a more diverse media ecology gave such protests more and more sympathetic coverage. 

During the [[w:Great Depression|Great Depression]], ethnic Germans in the [[w:Sudetenland|Sudetenland]] region of [[w:Czechoslovakia|Czechoslovakia]] were harder hit by increasing trade barriers than their non-German neighbors. They were therefore more open to populist and extremist movements such as fascism, communism and German irredentism.&lt;ref&gt;Wikipedia, &quot;[[w:Sudetenland|Sudetenland]]&quot;, esp. the section on &quot;[[w: Sudetenland#Within the Czechoslovak Republic (1918–1938)|Within the Czechoslovak Republic (1918–1938)]]&quot;, accessed 2026-05-05.&lt;/ref&gt; If those ethnic Germans had used nonviolent noncooperation to highlight their grievances, and if Czechoslovakia at that time had had a substantially more diverse media system, it seems likely that they could have gotten reasonable redress of grievances. If so, it would have been harder for Hitler to use that as an excuse to invade Czechoslovakia, as he did in 1938.&lt;ref&gt;Wikipedia, &quot;[[w:Occupation of Czechoslovakia (1938–1945)|Occupation of Czechoslovakia (1938–1945)]]&quot;, accessed 2026-05-05.&lt;/ref&gt; 

In 1940, during [[w:World War II|World War II]], Germany invade Denmark, which had previously declared neutrality. The Germans allowed [[w:1943 Danish Folketing election|Danish parliamentary elections in 1943]]; the Danish Nazi party won on 2.1% of the votes.&lt;ref&gt;{{cite web|title=Rigsdagsvalgene i Marts og April 1943|url=http://www.dst.dk/pukora/epub/upload/20217/valg1943.pdf|date=|publisher=Danmarks Statistic|accessdate=11 February 2021}}&lt;/ref&gt; When the Nazis ordered the Danes [[w:Rescue of the Danish Jews|to ship their Jews to the death camps, the Danes ignored those orders.]] When the Germans decided to do it themselves, a German diplomat leaked that decision, and nearly all Danish Jews escaped to neutral Sweden; 99% of Denmark's Jewish population survived the Holocaust.

An ideal settlement of the current Russo-Ukraine war might include training in nonviolent noncooperation made more effective through a more diverse media culture as suggested above. A substantial portion of the Ukrainian population, especially the Ukrainian military, are reported to be vicious anti-Russian Nazis, and the Ukrainian government has outlawed many uses of non-Ukrainian languages, especially Russian.&lt;ref&gt;Horton (2024).&lt;/ref&gt; A campaign of nonviolent noncooperation with a vigorous, diverse adversarial press would likely make it harder for Ukraine to continue any persecution of Russian speakers. It would also make it harder for major media in the US and Western Europe to suppress honest discussion of anti-Russian racism in Ukraine. Swanson (2022) said that the [[w:Baltic states|Baltic states]] have implemented such training in preparations for a possible Russian invasion; they might be asked to support such training in Ukraine (and elsewhere).&lt;ref&gt;Swanson (2022).&lt;/ref&gt; 

Organizations offering training in [[w:Nonviolent resistance|nonviolent noncooperation]] include [[w:Nonviolence International|Nonviolence International]] and the [[w:Highlander Research and Education Center|Highlander Research and Education Center]]. 

=== Civil resistance deters fracking ===

Duhamel (2013) claimed that well-advertised planning and training in nonviolent noncooperation helped deter oil companies from attempting hydraulic fracturing in [[w:Quebec|Quebec Province]] in [[w:Canada|Canada]]. Deterring a foreign invasion is different, but the same principle should apply: It's clear from many sources that elites consider nonviolence a threat; it's a felony to teach nonviolence to someone whom the US State Department claims supports a &quot;foreign terrorist organization&quot;, discussed in the next section.  

=== Life in prison for teaching nonviolence ===

Per the US Supreme Court decision in ''[[w:Holder v. Humanitarian Law Project|Holder v. Humanitarian Law Project]]'' (2010), teaching nonviolence to anyone whom the US State Department claims supports a foreign terrorist organization is &quot;[[w:Providing material support for terrorism|providing material support for terrorism]]&quot;, which is a felony under the USA [[w:Patriot Act|Patriot Act]] of 2001. Moreover, if the State Department claims that the death of any &quot;person&quot; resulted from the activities of the designated foreign terrorist organization, the penalty can be life in prison, where &quot;person&quot; is defined in the Patriot Act as &quot;any individual or entity capable of holding a legal or beneficial interest in property&quot;.&lt;ref&gt;The treatment of [[w:Sami Al-Arian|Sami Al-Arian]] is worth noting in discussing the Patriot Act. Al-Arian is a Kuwaiti-born political activist of Palestinian origin, who earned a doctorate in Electrical Sciences and Systems Engineering at [[w:North Carolina State University|North Carolina State]] in 1985 and taught computer engineering at [[w:University of South Florida|University of South Florida]] (USF) beginning in 1986. He was granted permanent resident status in 1989. In 1993 he earned a Distinguished Teacher Award as a tenured associate professor at USF. He was an [[w:imam|imam]] in a local [[w:mosque|mosque]] and led in other initiatives to promote dialogue and public policy initiatives between the West and Middle East. On September 26, 2001, he appeared on ''[[w:The O'Reilly Factor|The O'Reilly Factor]]'' where he was confronted with a 1988 recording of him shouting &quot;death to Israel&quot;. Al-Arian replied that &quot;Death to Israel&quot; meant &quot;death to occupation, ... apartheid, ...oppression,&quot; whereupon O'Reilly cut him off and called for the [[w:Central Intelligence Agency|Central Intelligence Agency]] to investigate him. Al-Arian spent most of the next 14 years between that 2001 interview and 2015 in detention, much of it in solitary confinement. This period included a 2005 trial that ended with acquittal on 8 counts and a hung jury on another 9. In 2015 he was deported to Turkey. In 2017, he founded the Center for Islam and Global Affairs at [[w:Istanbul Sabahattin Zaim University|Istanbul Sabahattin Zaim University]] in Istanbul, Turkey, which he directs. What has been the impact of treatment of Al-Arian on the well-being of the bottom 99 percent of the US and world population?&lt;/ref&gt; 

How did these provisions get written into the Patriot Act? 

That's a question that deserves research, perhaps by asking elected officials in the US Congress and lobbying for their repeal. A speculation consistent with the thesis of this book is that nonviolence terrifies those who control most of they money for the media, because it threatens their ability to get their security forces to follow orders.

==3. Forbid uses of force beyond one’s own borders and covert interference in foreign countries ==

:''[[w:Si vis pacem, para bellum|If you want peace, prepare for war.]]''
:  -- ''[[w:De Re Militari|De Re Militari]]'' by [[w:Publius Flavius Vegetius Renatus|Publius Flavius Vegetius Renatus]] (fourth or fifth century AD)

The record of history is now clear: Those who prepared for war often got war initiated when one party claimed they were being attacked or about to be attacked and believed they would fare better by attacking. Sometimes this occurred when the media environment convinced leaders that their political futures required them to clandestinely provoke foreign entities to do things that could then be denounced as unprovoked to justify military escalation, as mentioned in the previous section.  

Samuelson (2025) summarized quantitative analyses of 60 insurgencies since World War II, whose findings included the complete absence of success with counterinsurgencies without large force ratios (at least four, and most often more than ten, times the force of the insurgents) and without &quot;providing a path toward peaceful addressing of grievances&quot;. He also noted that, &quot;Brutality toward the civilian population ... tends to inflame the insurgency.&quot;&lt;ref&gt;Samuelson (2025) summarized Lawrence (2015).&lt;/ref&gt; His analysis gave a pessimistic prognosis for the [[w:Gaza war|Gaza war]] that began 2023-10-07. His conclusions are consistent with the history of the current [[w:Russo-Ukrainian war|Russo-Ukrainian war]], the [[w:Vietnam War|Vietnam War]], the [[w:Graveyard of empires|First, Second, and Third Anglo-Afghan Wars (1839-1919), the Soviet-Afghan War (1979–1989), the US-led War in Afghanistan (2001–2021)]], the 2001-2011 [[w:Iraq War|Iraq War]], and others. 

A key point is that invaders often to lose unless they enter with overwhelming force like Germany in the early stages of World War II: The [[w:Occupation of Czechoslovakia (1938–1945)|Czechoslovaks]], [[w:Invasion of Poland|Poles]], [[w:France during World War II|French]], and others were not prepared to fight the Germans, but the [[w:Soviet Union in World War II|Soviets]] were. [[w:Adolf Hitler|Hitler]] doubtless knew that the [[w:Switzerland during World War I and World War II|Swiss]] were prepared to fight, so he attacked other countries first. While fighting the [[w:Russo-Ukrainian war#Full-scale Russian invasion of Ukraine (2022)|Russian invasion]] that began 2022-02-24, [[w:Defense industry of Ukraine|Ukraine has developed]] military drones that are highly effective relative to the cost, as witnessed by sales of such to Gulf Arab states,&lt;ref&gt;Sharawi and Shapiro (2026).&lt;/ref&gt; illustrating the point that foreign invaders often encounter vastly more resistance than they expect -- and should expect highly effective resistance if they invade a country prepared to fight on their own territory. 

The rest of this section discusses weaknesses with standard deterrence theory. 

===Deterrence theory and nuclear Armageddon=== 

Standard [[w:Deterrence theory|deterrence theory]] assumes that one's opponents are rational and do not want [[w:Armageddon|Armageddon]]. The record of history summarized above raises questions about this assumption: In World War I, even the &quot;winners&quot; arguably lost more than they gained -- doubtless excepting a few merchants, who made fortunes from what they sold. Many of the other military decisions discussed above seem to have been driven more by the media than military necessity. 

Beyond that, at least some portions of the [[w:Islamic State|Islamic State]] reportedly violates this assumption, because it &quot;not only believes in the literal meaning of the coming Armageddon – it sees itself as its chief protagonist.&quot;&lt;ref&gt;Misra (2015).&lt;/ref&gt; Some [[w:Christian nationalism|Christian nationalists]] promoted to command positions by [[w:United States Secretary of Defense|US Secretary of Defense]] [[w:Pete Hegseth|Hegseth]] and President Trump also seem to believe that Armageddon might be desirable. On 2026-03-03 the [[w:Military Religious Freedom Foundation|Military Religious Freedom Foundation]] said they had received over 200 complaints from over 50 different US military installations with comments like, &quot;President Trump has been anointed by Jesus to light the signal fire in Iran to cause Armageddon and mark his return to Earth&quot;, per an email from one [[w:Non-commissioned officer|NCO]].&lt;ref&gt;Nick Mordowanec (2026).&lt;/ref&gt; With Hegseth holding monthly Christian worship services in the Pentagon during business hours,&lt;ref&gt;Black (2025), Mayes-Osterman (2025). See also the section on &quot;[[w:Pete Hegseth#Pentagon Christian worship services and &quot;biblically sanctioned war&quot;|Pentagon Christian worship services and &quot;biblically sanctioned war&quot;]] in the Wikipedia article on [[w:Pete Hegseth|Pete Hegseth]], accessed 2026-05-14.&lt;/ref&gt; this suggests that Hegseth could have appointed enough Christian nationalists to key positions to initiate nuclear attacks on Iran or Russia, claiming that President Trump had ordered such whether he had or not.&lt;ref&gt;The [[w:Gold Codes|Gold Codes]] carried in the &quot;[[w:nuclear football|nuclear football]]&quot; required by the [[w:Permissive action link|permissive action link]]s would ''not'' prevent Hegseth and a few others appointed by him from initiating nuclear Armageddon, according to Ellsberg, who had been a nuclear war planner for presidents Eisenhower, Kennedy, Johnson, and Nixon, before releasing the ''[[w:Pentagon Papers|Pentagon Papers]]''. Ellsberg (2017, p. 69) insisted that the security provided by those Gold Codes were a hoax, because otherwise a single nuclear detonation on Washington, DC, when both the president and vice president were in town &quot;would would definitively block any authorized, coordinated nuclear response to that or any subsequent nuclear attack.&quot;&lt;/ref&gt; 

The biggest risk today may be the risk of [[w:Nuclear holocaust|nuclear Armageddon]], which seems on average to grow over time consistent with experience with &quot;[[w:system accidents|system accidents]]&quot; in other fields: It is naive to assume that any system as complex as military command, control and communications systems never fail. And managers of complex systems subject to rare, catastrophic failures &quot;learn&quot; from experience that they can take ever greater risks, because they have &quot;safely&quot; done so in the past — until there is a catastrophe:&lt;ref&gt;Kahneman and Klein (2009) found that expert intuition, when it exists, is learned from frequent, rapid, high quality feedback. With anything nuclear, mishaps are so rare that managers develop &quot;expert intuition&quot; that they can &quot;safely&quot; ignore safety concerns -- until there is a catastrophe. See also Sagan (1993).&lt;/ref&gt; 

Veterans for Peace (2022) recommend global reduction and rapid elimination of nuclear weapons &quot;to reduce the real risk of nuclear confrontation through accidental launch or miscalculated escalation&quot;. 

==== National security tariffs ====

Free trade agreements supported by the [[w:World Trade Organization|World Trade Organization]] allow exemptions for national security and other objectives. [[Responding to a nuclear attack|Even a minor nuclear war between India and Pakistan would have a negative impact on the entirety of humanity]]. It might therefore be sensible for parties to the [[w:Treaty on the Prohibition of Nuclear Weapons|Treaty on the Prohibition of Nuclear Weapons]] (TPNW) to institute gradually increasing tariffs on nuclear weapon states, not so great as to seriously impact the economy of the nation applying such tariffs but aggressive enough to gradually wean their economy from reliance on trade with nuclear-weapon states that refuse to support the TPNW.

===Research on the effectiveness of deterrence and implications=== 

Lebow and others have provided substantial documentation of case studies claiming that leaders are often not rational, and deterrence based on threatening use of military force beyond one’s own borders has been ''as likely to provoke as prevent'' undesired behavior.&lt;ref&gt;Lebow (2025, 2024), Lebow et al. (2023).&lt;/ref&gt; The most obvious portions of this threat can be entirely eliminated by policies clearly and effectively forbidding use of force beyond one’s own borders. This can be signaled in at least three ways: 

* Eliminate all weapon systems like missiles and aircraft with a range of more than, e.g., a hundred miles or 200 kilometers with the possible exception of surveillance only aircraft that cannot be easily configured to carry [[w:Materiel#Military|ordnance]], e.g., explosives. Similarly eliminate nuclear weapons, which few if any countries would want to use for military defense inside their own borders. 

* Supply a national guard and reserves with weapons, training, and rules of engagement that prohibit projecting force beyond one’s own borders. Train them also in development and use of improvised explosive devices and other tactics and devices like low cost military drones. 

:Afghanistan is said to be the &quot;[[w:Graveyard of empires|Graveyard of empires]]&quot;. They defeated the British three times (1839–1842, 1878–1880, 1919), the Soviet Union (1979–1989), and the US (2001–2021). Each victory came with foreign supplies, but any foreign troops helping Afghanis were primarily under the command of local leaders. 
:The [[w:2003 invasion of Iraq|2003 invasion of Iraq]] might have produced [[w:Nation-building|nation-building]] more like the experience of [[w:Nation-building#Germany and Japan after World War II|Germany and Japan after World War II]] if the US had mandated a vigorous adversarial press instead of strict censorship, according to McChesney and Nichols.&lt;ref&gt;McChesney and Nichols (2010, Appendix II. Ike, MacArthur and the Forging of Free and Independent Press, pp. 241-254).&lt;/ref&gt; This claim by McChesney and Nichols was not endorsed by [[News from Germany 1900-1945 and implications for today#After the war in Germany vs. Iraq|University of British Columbia History professor Heidi Tworek]], who said the democratization efforts in Germany and Japan after World War II were more complicated than that implied by that brief discussion by McChesney and Nichols.&lt;ref&gt;The 2025-07-03 interview with Tworek is available at &quot;[[News from Germany 1900-1945 and implications for today]]&quot;, accessed 2026-05-14.&lt;/ref&gt; However, the research by Usher and Kim-Leffingwell (2022) and the related research on news deserts summarized in the preface to this ''[[Media Literacy and You]]'' book largely supports those claims by McChesney and Nichols.
:[[w:Defense industry of Ukraine|Ukraine has become a world leader in military drones]], many of which are dramatically cheaper than alternatives. Most of those have limited range but have been useful for reconnaissance and delivery of ordnance and improving targeting of, e.g., surface to air missiles. 
:[[w:Eliot A. Cohen|Eliot Cohen]], who served as a special advisor to [[w:United States Secretary of State|US Secretary of State]] [[w:Condoleezza Rice|Condoleezza Rice]] from 2007 to 2009, wrote, &quot;As the United States discovered in Iraq and Afghanistan, no matter how large, technologically advanced, and proficient an army is, motivated insurgents can still inflict casualties in the tens of thousands.&quot;&lt;ref&gt;Cohen (2022), cited from Horton (2024, p. 1026).&lt;/ref&gt; Cohen recommended we &quot;Arm the Ukranians now&quot;. Horton said that the neoconservatives learned from Iraq War II and Afghanistan that the US &quot;should fight like those who defeated them.&quot;&lt;ref&gt;Horton (2024, p. 1026).&lt;/ref&gt; 
:Leading economist [[w:Jeffrey Sachs|Jeffrey Sachs]] addressed the European Parliament 2025-02-19, claiming that the tragedy that befell Serbia in 1999 and subsequent US uses of force in Iraq and Syria, plus wars in Africa including Syria, Somalia and Libya and the current wars in Ukraine and the Israel-Hamas war, &quot;are to a very significant extent the result of deeply misguided US policies.&quot;&lt;ref&gt;Sachs (2025-02).&lt;/ref&gt; He said that Europe should craft its own foreign and military policies, independent of the US. ''[[w:Le Monde Diplomatique|Le Monde Diplomatique]]'' noted that Sachs' speech has circulated among social media since ''but has yet to be seriously discussed by major European media.''&lt;ref&gt;Sachs (2025-04; emphasis added).&lt;/ref&gt; 

* Change the laws of government secrecy so government officials cannot secretly interfere in the internal affairs of foreign countries or otherwise project force outside their own borders. This might be achieved in the US in part by requiring anyone with information about questionable actions by government officials to provide such documentation to one or more congressional oversight bodies while also allowing any current or former government employee or contractor to file suit in any US federal jurisdiction if they feel they have been punished for refusing to support questionable activities. In addition, federal judges should be authorized to subpoena classified government documents that may be relevant to any case in their jurisdiction and declassify them subject to appellate review if they believe the national interest would be better served by declassification. 

:If the law is changed without a substantive [[#1. Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content.|citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference]], as discussed above, the change could be merely cosmetic and unconvincing to local public officials and potential adversaries. 
:Connelly (2023) noted that US government secrecy has in the past encouraged administration officials to do things to provoke actions by foreign entities that can then be denounced as “unprovoked” to stampede the US Congress and the public into supporting counterproductive uses of military force, as discussed above.&lt;ref&gt;See also Connelly et al. (2023).&lt;/ref&gt; A more diverse media culture should make it harder for administration officials to lie to the public and to Congress — and harder to punish government employees who tell their managers that they should not lie to Congress, as they reportedly did to [[#Richard Barlow and nuclear proliferation|Richard Barlow]], mentioned above. 
:The Barlow case and many others explain why the US should, e.g., give federal judges the authority to subpoena classified documents and declassify them if they believe the public good is better served from declassification than continued secrecy.&lt;ref&gt;See, e.g., the 2025-05-08 interview with Seth Stern and Lauren Harper discussing what the &quot;[[Freedom of the Press Foundation says...]]&quot;, Graves (2014), and [[w:Moynihan Commission on Government Secrecy|Moynihan Commission on Government Secrecy]], accessed 2026-05-06. Graves (2021) recommends &quot;Congressional Gold Medals for&quot; Barlow and whistleblowers.&lt;/ref&gt; 

These policies would make it hard for any foreign leader to justify an attack for multiple reasons: First, it would be difficult to convince their supporters that such an attack is necessary. Second, a rational foreign leader might be hesitant to invade a country that is prepared to fight a guerrilla war. Germany reportedly considered invading [[w:Switzerland during World War I and World War II|Switzerland during both World Wars I and II]] and decided against it in part because Switzerland had large, well-trained ready reserves, who were ready to fight. Belgium seemed to be an easier route.&lt;ref&gt;Documented in Wikipedia, &quot;[[w:Switzerland during World War I and World War II|Switzerland during World War I and World War II]]&quot;, accessed 2026-05-06. Switzerland also has many mountains, which make it easier to defend, but the capabilities of the Swiss military also influenced the German decision to avoid Switzerland.&lt;/ref&gt; Third, even if foreign invaders defeat the guerrillas, they should not assume that their invading forces would continue to follow orders. [[w:Rescue of the Danish Jews|Ninety-nine percent of Danish Jews reportedly survived World War II]] because of Danish noncooperation ''supported by a German diplomat''.&lt;ref&gt;Wikipedia, &quot;[[w:Rescue of the Danish Jews|Rescue of the Danish Jews]]&quot;, accessed 2026-05-06.&lt;/ref&gt; 

With policies like these in place, it would be hard for foreign leaders to convince their supporters of a need to attack, as [[w:2022 Russian invasion of Ukraine|Putin did when invading Ukraine in 2022]],&lt;ref&gt;The Wikipedia article on &quot;[[w:2022 Russian invasion of Ukraine|2022 Russian invasion of Ukraine]]&quot;, accessed 2026-05-06, includes a paragraph saying, 'In July 2021, Putin published an essay &quot;On the Historical Unity of Russians and Ukrainians&quot;, in which he called Ukraine &quot;historically Russian lands&quot; and claimed there is &quot;no historical basis&quot; for the &quot;idea of Ukrainian people as a nation separate from the Russians&quot;'. Putin was accused of promoting Russian imperialism, historical revisionism and disinformation. Writing in 2024, Michael McFaul and Robert Person described this essay as representing not only &quot;cynical propaganda&quot; but also Putin's &quot;deeply held and internalized beliefs&quot;. See the Wikipedia article for references supporting those claims.&lt;/ref&gt; as [[w:2025 India–Pakistan crisis|India did when attacking Pakistan in 2025]], and as [[w:Invasion of Poland|Hitler did when invading Poland in 1939]], to name only three examples. 

=== If we continue to base deterrence on threats === 

There are now calls for Europe to get their own nuclear weapons,&lt;ref&gt;Burgard (2025).&lt;/ref&gt; while Iran, Saudi Arabia, Turkey, South Korea and Taiwan have been suggested as other candidates for acquiring nuclear weapons should they feel a sufficient need.&lt;ref&gt;Ruehl (2024).&lt;/ref&gt; 

It is difficult to imagine how the number of nuclear weapon states could be increased without increasing the risks of a nuclear war, consistent with the discussion of &quot;[[w:system accident|system accident]]s&quot; earlier in this chapter.

Secondarily, intelligence services with information on political corruption including attempts to intimidate and murder journalists should not be allowed to keep that information secret: They should be required to find ways to leak that information to journalists. Such attacks on journalists in their own country should be exposed and prosecuted if the evidence seems likely to obtain a conviction. Intelligence services with information about such attacks in other countries should be required to find ways to leak it to competent journalists without identifying their sources and methods: Doing so would likely reduce political corruption worldwide and with that the risks of war. 

== Collateral damage ==

The research cited above supports the claim that, 

:''[[w:Collateral damage|Collateral damage]] that our designated enemies commit prove to us that they are subhuman or criminally misled.''
:''Meanwhile, collateral damage that we commit is unfortunate but necessary -- from our perspective. However, it proves to our designated enemies that we are subhuman or criminally misled.'' 

This observation supports this entire program of deterrence without threat: 
* Forbidding use of force beyond one’s own borders and covert interference in foreign countries would automatically reduce collateral damage. It would also avoid uses of force that seem not to contribute to broadly shared peace and prosperity, according to research cited above. 
* The effectiveness of nonviolent noncooperation rests in part on its near universal avoidance of collateral damage. 
* Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content should make it much harder for major media to convince the public to do things contrary to their best interests, like invading or interfering covertly in foreign countries. 

== Call for help == 

Do you, dear reader, know other serious research not cited herein that might improve this analysis? If yes, you can help improve this discussion by adding comments with citations -- or by adding such citation(s) to the &quot;Discuss&quot; page associated with this chapter, suggesting someone else revise the chapter appropriately. 

There are plenty of contrary claims in the major media, but the lead author of this chapter is not aware of any that are based on serious research. 

In the absence of such research, the current author finds it difficult to imagine any national defense policies that carry a greater risk of nuclear Armageddon than our current policies, as discussed in the next chapter of this book on ''[[Media Literacy and You]]'' on &quot;[[Media Literacy and You/Responding to a nuclear attack|Responding to a nuclear attack]]&quot;. That chapter, in sum, claims that the ''worst'' response to a nuclear attack would be nuclear response, because it would escalate a catastrophe killing millions of humans to one killing ''billions'', possibly 80 percent of humanity in a war between the US and Russia that lofts so much smoke from burning cities to the stratosphere where it covers the globe depressing crop yields for years during with 99 percent of the humans in the US, Europe and Russia would starve to death if they did not die of something else sooner. Moreover, the record of &quot;[[w:System accident|system accident]]s&quot; suggests that the chances of such a war before the end of this century is substantially greater than the 40 percent median estimate based on history mentioned in a presentation on &quot;[[Time to nuclear Armageddon]]&quot; delivered to the 2019 Joint Statistical Meetings. 

This chapter is being written in the hopes of inspiring action to improve the prospects for broadly shared peace and prosperity for the long term. 

== Exercises ==

1. Disconfirmation bias: Brainstorm your biggest concerns about a current or possible future war. 
:1.1. Select the one that is of greatest concern to you currently. 
::One issue that may not be a major concern for many but might elicit a broad consensus for action would be a campaign to ask elected officials in the US Congress to explain how we benefit from the provisions of the USA Patriot Act of 2001 that authorize [[#life in prison for teaching nonviolence|life in prison for teaching nonviolence]]. 
:1.2. Who are your designated enemies? 
:1.3. Research what your designated enemies are saying about your biggest concern.  
:1.4. Under what circumstances would you support what you see your designated enemies advocating or doing? 
::If you cannot see such circumstances, expand your research: Look for more sources that support your designated enemies. 

2. Interacting: Ask others if you can share what you've learned about that conflict. If they say, &quot;No&quot;, don't push it. If they agree, share what you've learned in a friendly supportive manner without saying that anything is &quot;true&quot;. 

::''Show me someone who knows the truth, and I will show you someone who is dangerous.''

:2.1. The primary goal in this is ''not'' to convince anyone that you are right and they are wrong but to lower the level of anger and increase the level of tolerance for dissenting views. 
:2.2. Another goal is to comfortably enjoy civil conversations of this nature, agreeing to disagree agreeably and building trusting relationships that support collaboration on issues of common concern. 
:2.3. After becoming adept at building collaborations on issues of common concern, you might consider teaching this important skill and approach to issues.  

3. Teaching: Each one teach two, as discussed in the section on &quot;[[Media Literacy and You#Text and self-help book and point of discuss|Text and self-help book and point of discuss]]&quot; in the preface to this book.

:''Humanity is one misunderstanding, one miscalculation away from nuclear annihilation. ... This is madness. We must reverse course.''
:  -- [[w:António Guterres|UN Secretary General António Guterres]]  (2022)&lt;ref&gt;Jacobsen (2024), BBC (2022).&lt;/ref&gt;

:This book is a combination instruction manual on [[w:Media literacy|media literacy]] and an invitation to you to support collaborative / crowd-sourced research on how to improve the world's understanding of media literacy and how to accelerate its understanding and use globally for the betterment of humanity. 

Part I of this book on ''[[Media Literacy and You]]'' discusses &quot;The media and political economy&quot;. Except in times of terror, massive lawlessness or war, most humans place a high priority on their financial situation, the primary focus of Part I. Part II on &quot;The media and war&quot; focuses on security concerns starting with this chapter on &quot;Deterrence without threat&quot;. 

== Introduction ==

Every individual and group has a right and an obligation to defend itself. Unfortunately, when most humans&lt;ref&gt;We distinguish here between &quot;humans&quot; and &quot;people&quot; or &quot;persons&quot;, because under current US law, corporations are &quot;people&quot; and money is speech, per the US Supreme Court decision in ''[[w:Citizens United v. FEC|Citizens United v. FEC]]'' (2010) and many other judicial rulings and US law such as the [[w:Patriot Act|Patriot Act]] of 2001.&lt;/ref&gt; think of defense, they often think of violent responses to provocations. 

However, there is a growing body of research documenting 

:(a) how most uses of violence are counterproductive, and 
:(b) there are usually nonviolent options to violence that would more effectively promote broadly shared peace and prosperity for the long term. 

This research is rarely discussed by major media outlets, because it would offend the &quot;people&quot;&lt;ref&gt;We put &quot;people&quot; in quotes in this essay, because that term includes corporations under current US law.&lt;/ref&gt; who control most of the money for the media: Nonviolence threatens their ability to get compliance from security forces. As a result, many elites prefer to use force to the detriment of the bottom 99 percent of humanity. As discussed below, a military posture that supports projecting force beyond one’s own borders may be as likely to ''provoke'' as ''prevent'' an attack.&lt;ref&gt;For example, Lebow (2025) cites some of his previous work with others to support the claim that large militaries have been &quot;more provocative than preventative in&quot; their effects. And Lebow (2024) insists that, &quot;Policymakers respond more instinctively than analytically in deciding that some policy is or is not in the national interest.&quot; See also Lebow et al. (2023).&lt;/ref&gt; 

This chapter outlines a 3-part strategy that research suggests would more likely lead to better outcomes for the vast majority of humans: 

# Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content. 
# Training in nonviolent noncooperation for anyone willing to listen. 
# Forbid uses of force beyond one’s own borders and covert interference in foreign countries. 

We now discuss each of these briefly. 

== 1. Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content. == 

It seems that

:''Primary drivers of every major conflict include differences between the media that the different parties find crecible.''

In a recent interview with [[w:Fordham University|Fordham University]] Professor Emerita of Communications Robin Andersen,&lt;ref name=Andersen&gt;&lt;!--Robin Andersen--&gt;{{cite Q|Q132982358}}&lt;/ref&gt; she agreed with this claim and added: 

:''We only have enemies of our very own making.''

The media are involved in this, because:  

:''The major media create the stage upon which politicians read their lines.''&lt;ref&gt;In 1791 James Madison, who represented part of Virginia in the US House of Representatives 1789-1801 and later became the 4th President of the US (1809-1819), said, &quot;Public opinion sets bounds to every government, and is the real sovereign in every free one.&quot; Quoted from the ''[[w:National Gazette|National Gazette]]'' (published 1791-1793) by Schmeller (2009, p. 36) and Sauer (2016, p. 5). Sauer described how the American Revolutionaries, especially the first four US presidents, planted stories in newspapers to build support for how they dealt with the [[w:Barbary corsairs|Barbary pirates]], who were seizing merchant ships, raiding European coastal towns and villages, and selling European captives into slavery. The first two US presidents, [[w:George Washington|Washington]] and [[w:John Adams|Adams]], used that support for protecting US shipping and citizens by paying tribute to government leaders in Morocco, Algeria, Tunisia, and Libya. The next two presidents, [[w:Thomas Jefferson|Jefferson]] and [[w:James Madison|Madison]], convinced Congress to fund a navy and marines to fight the [[w:Barbary Wars|Barbary Wars]]. This included the [[w:Battle of Derna (1805)|Battle of Derna]]  (April-May 1805), memorialized in the [[w:Marines' Hymn|Marines' Hymn]], which mentions actions &quot;to the shores of Tripoli&quot;. Sauer described how the policies were sold to the public via planted stories in the different partisan newspapers.&lt;/ref&gt; 

This works because (a) virtually everyone thinks they know more than they do ([[w:Overconfidence effect|overconfidence effect]]), and (b) virtually everyone prefers information and sources consistent with preconceptions ([[w:confirmation bias|confirmation bias]]). 

Also, in many, perhaps all, countries, the primary constituency for foreign and military policy is the people with foreign business interests. Many of these people also control substantial portions of the money for the media, which have too often encourage questionable and counterproductive uses of military force.&lt;ref&gt;If we [[w:follow the money|follow the money]], we might find that &quot;watchdogs generally protect the people who feed them&quot;, as discussed in the 2025-09-25 interview with British journalist and media reform activist Dan Hind discussing how the British [[Media Reform Coalition challenges anti-democratic media bias in the UK]].&lt;/ref&gt; 

=== Examples === 

A leader in documenting the role of the media in armed conflict is Robin Andersen,&lt;ref&gt;e.g., Andersen (2006, 2026).&lt;/ref&gt; but she is not alone. For example, [[w:University of Denver|University of Denver]] journalism professor Kareem El Damanhoury&lt;ref name=Daman&gt;&lt;!--Kareem El Damanhoury--&gt;{{cite Q|Q113752441}}&lt;/ref&gt; has compared how [[w:Gaza Strip|Gaza]] has been framed differently by [[w:Al Jazeera Media Network|Al Jazeera]], the [[w:BBC|BBC]]&lt;ref&gt;El Damanhoury et al. (2025).&lt;/ref&gt; and [[w:Fox News|Fox]].&lt;ref&gt;El Damanhoury and Saleh (2024).&lt;/ref&gt;&lt;ref&gt;Some of El Damanhoury's work in this regard [[Differences between media outlets including coverage of Gaza|is reviewed in a 2025-11-20 interview with him]].&lt;/ref&gt; 

==== World War I ====

Andersen's (2006) ''A Century of Media, A Century of War'' begins with a discussion of &quot;The birth of war propaganda&quot; in &quot;The Great War and the Fight between Good and Evil&quot;.&lt;ref&gt;Andersen (2006, ch. 1)&lt;/ref&gt; 

A more detailed but compatible discussion of the media and [[w:World War I|World War I]] is given by [[w:John Maxwell Hamilton|John Maxwell Hamilton]]. Among other things, he said: {{quote|

The first iron law of propaganda is that only the enemy does it.&lt;ref&gt;Hamilton (2020, p. 642). See also the [[John Maxwell Hamilton on American propaganda|2025-12-11 interview with Hamilton]].&lt;/ref&gt;}} 

[[File:MB Walker - German bayoneting children - Life - July 25, 1915.png|thumb|left|Figure 1. Stories of German soldiers impaling children on their bayonets were widely reported during the war. However, no credible evidence was found to support these claims when questions were raised after the war.&lt;ref&gt;{{cite web|title=Alleged German atrocities: Bryce report|url=http://www.nationalarchives.gov.uk/pathways/firstworldwar/spotlights/p_alleged_german.htm|publisher=The National Archives|access-date=13 July 2014}}&lt;/ref&gt;]]

Andersen (2006, pp. 8-9) said, {{quote|

James Bryce, the former British ambassador to the United States, ... helped prepare a sixty-one page ''Report on the Committee on alleged German Outrages'', which was translated into thirty languages and was said to be based on twelve hundred depositions ... included gruesome and titillating details of how German soldiers publicly raped Belgian girls in the marketplace at Liege and bayonetted a two-year-old child. ... [A]fter the war a Belgian commission of inquiry found no evidence for any major accusation in the report. ...}}
{{quote|
German propagandists, on the other hand, ... &quot;bungled, because they were naïve: they thought the success of the war depended almost solely on military strategy and therefore they tended to neglect propaganda.&quot; ... Thus, when German soldiers shot some Allied nurses who had carried weapons, they admitted it openly. The Allies reported the incident as an atrocity and featured it in press propaganda. When French troops shot German nurses under similar circumstances, the Germans failed to exploit it.}} 

==== Jonathan Swift 1710 ====

This is not limited to World War I. In 1710, [[w:Jonathan Swift|Jonathan Swift]] reportedly said, &quot;Falsehood flies, and truth comes limping after ... like a physician, who hath found out an infallible medicine, after the patient is dead.&quot;&lt;ref name=Swift&gt;Excerpted from a line in [[Wikiquote:Jonathan Swift]] consulted 2026-04-13.&lt;/ref&gt;  

==== The Marines' Hymn ====

The [[w:Marines' Hymn|Marine Corps Hymn]] begins, {{quote|

From the Halls of Montezuma

To the shores of Tripoli;

We fight our country's battles

In the air, on land, and sea.}}

The &quot;[[w:Battle of Chapultepec|Halls of Montezuma]]&quot; refer to the [[w:Mexican–American War|Mexican–American War]], which was fought to expand slavery first into [[w:Texas|Texas]]  -- and supporters of slavery hoped that would help expand slavery further west. The &quot;[[w:Battle of Derna (1805)|shores of Tripoli]]&quot; were part of the [[w:Barbary Wars|Barbary Wars]], which were fought to reduce the need to pay (a) tribute to the [[w:Barbary Coast|Barbary or Berber]] states of [[w:Morocco|Morocco]], [[w:Algeria|Algeria]], [[w:Tunisia|Tunisia]], and [[w:Libya|Libya]] or (b) ransom to [[w:Barbary corsairs|Barbary pirates]], who were otherwise capturing Christians and selling them into slavery. 

Did the bottom 99 percent of the US population of that time benefit? Or did these wars (and any tribute and ransom paid by the US government before the Barbary wars) constitute a hidden transfer of wealth from the poor to the wealthy? 

A partial answer to this question is that [[w:tariff|tariff]]s on imported goods covered between 80 and 95 percent of all federal revenue up to 1860, and [[w:excise|excise taxes]] on only a few goods, such as whiskey, rum, tobacco, snuff and refined sugar, made up nearly all the rest.&lt;ref&gt;See the section on &quot;[[w:Excise tax in the United States#Historical background|Historical background]]&quot; in the Wikipedia article on &quot;[[w:Excise tax in the United States|Excise tax in the United States]]&quot;, accessed 2026-05-26.&lt;/ref&gt; The money raised from taxes on income during the Civil War, visible in Figure 3 above, were apparently negligible as a portion of federal revenue during the Barbary Wars and the Mexican-American War.  

==== Gulf of Tonkin Resolution: &quot;Betray the nation or do not get elected.&quot; ====

Regarding the [[w:Vietnam War|Vietnam War]], former president [[w:Dwight D. Eisenhower|Eisenhower]] wrote in his autobiography, which appeared in 1963 (he left the presidency 1961-01-20), that he had never communicated {{quote|

with a person knowledgeable in Indochinese affairs [including Vietnam] who did not agree that had elections been held as of the time of the fighting [leading to the defeat of the French in 1954], possibly 80 per cent of the population would have voted for the Communist [[w:Ho Chi Minh|Ho Chi Minh]].&lt;ref&gt;Eisenhower (1963, p. 372).&lt;/ref&gt;}}

[[w:Joseph McCarthy|Joseph McCarthy]], who had been elected to the US Senate in 1946 and &quot;experienced a meteoric rise in national profile beginning on February 9, 1950, when he gave a&quot; speech during which he said something like, &quot;The [[w:United States Secretary of State|State Department]] is infested with communists. I have here in my hand a list of 205—a list of names that were made known to the Secretary of State as being members of the Communist Party and who nevertheless are still working and shaping policy in the State Department.&quot; McCarthy's mostly baseless claims went largely unchallenged in the media, including accusing the Democrats of &quot;twenty years of treason&quot; for having been allied with the Soviet Union, which took the bulk of casualties during World War II. 

By the end of 1953 with (Republican) Eisenhower as president roughly 11 months, McCarthy was complaining about &quot;''21'' years of treason&quot;, complaining that Eisenhower was not sufficiently aggressive in rooting out the communists who McCarthy claimed were in the government.&lt;ref&gt;Fried (1997, p. 179).&lt;/ref&gt; 

Then the French were defeated by Vietnamese communists 1954-05-07 in the [[w:Battle of Dien Bien Phu|Battle of Dien Bien Phu]]. The [[w:1954 Geneva Conference|1954 Geneva Conference]], which had begun eleven days earlier, 1954-04-26, concluded 1954-07-21 with the &quot;Geneva Accords of 1954&quot;.&lt;ref&gt;The [[w:Battle of Dien Bien Phu|Battle of Dien Bien Phu]], 1954-05-07, effectively ended the [[w:First Indochina War|French Indochina War]]. This led to the [[w:1954 Geneva Conference|Geneva accords of 1954]], officially dated 1954-07-20 but actually signed the following morning. Those accords took effect on three different dates, July 27 and August 1 and 11 in three different sectors of Vietnam. See &lt;!--Agreement on the Cessation of Hostilities in Vietnam--&gt;{{cite Q|Q139676410}}&lt;/ref&gt; Those accords called for UN-supervised elections for July of 1956, when Eisenhower would presumably be campaigning for reelection. Eisenhower doubtless knew that he might lose his bid for re-election in 1956, if the Communist Ho Chi Minh won elections in July of that year. 

:''The consistent suppression of honest portrayal in the major media of that day of the perspective of anyone whom Eisenhower considered &quot;knowledgeable in Indochinese affairs&quot; gave him -- and his successors [[w:John F. Kennedy|Kennedy]], [[w:Lyndon B. Johnson|Johnson]], and [[w:Richard Nixon|Nixon]] -- the choice between betraying the nation or not getting elected.'' 

In this environment, the [[w:Operation 34A|US initiated a series of clandestine operations against North Vietnam]] including infiltrating CIA-recruited spies and supporting attacks against North Vietnam by South Vietnamese commandos.&lt;ref&gt;Paterson (2008).&lt;/ref&gt; This included a raid 1964-07-30 by South Vietnamese commandos on the island of Hòn Mê, roughly 300 km (180 miles) north of the [[w:Vietnamese Demilitarized Zone|Vietnamese Demilitarized Zone]] in the [[w:Gulf of Tonkin|Gulf of Tonkin]], covered by [[w:DESOTO patrol|US naval vessels]] patrolling in that area. Then during a dark and stormy night six days later, US naval vessels opened fire on radar snow, and President Johnson requested and received Congressional approval of the [[w:Gulf of Tonkin Resolution|Gulf of Tonkin Resolution]]; then-[[w:United States Secretary of Defense|US Secretary of Defense]] [[w:Robert McNamara|McNamara]] claimed those attacks were &quot;unprovoked&quot;.&lt;ref&gt;Karnow (1983, p. 375). See also the section on [[w:Gulf of Tonkin Resolution#Congress votes|Congress votes]]&quot; in the Wikipedia article on [[w:Gulf of Tonkin Resolution|Gulf of Tonkin Resolution]], accessed 2026-05-14.&lt;/ref&gt;

In this media environment, only two officials in the US Congress voted against the Gulf of Tonkin Resolution: [[w:Ernest Gruening|Ernest Gruening]] (D-AK) and [[w:Wayne Morse|Wayne Morse]] (D-OR). Gruening lost in his next primary campaign to [[w:Mike Gravel|Mike Gravel]], and Morse lost in his next general election campaign to [[w:Bob Packwood|Bob Packwood]]. These results support the previous claim that the major media give politicians the choice: 

:''Betray the nation, or do not get elected.''

That resolution became the primary authorization for the US war in Vietnam until Congress ended the funding. 

==== Was the Vietnam War lost in Washington or by media biases? ====

[[w:John Mueller|John Mueller]], prolific author, Professor Emeritus of international relations at [[w:Ohio State University|Ohio State University]] and Senior Fellow at the [[w:Cato Institute|Cato Institute]], said that the most effective thing the US did to win the [[w:Cold War|Cold War]] was —

:''nothing'': 

Between the [[w:Fall of Saigon|Fall of Saigon]] in 1975 and the inauguration of [[w:Ronald Reagan|Ronald Reagan]] as President of the US, the US &quot;went into a sort of containment funk: it effectively adopted a policy of complacency (or perhaps of appeasement) as it watched from the sidelines as the Soviet Union … opportunistically gathered a set of Third World countries into its imperial embrace: Angola in 1976, Mozambique and Ethiopia in 1977, South Yemen and Afghanistan in 1978, Grenada and Nicaragua in 1979.&quot;&lt;ref&gt;Mueller (2021,  p. 59).&lt;/ref&gt; Nearly all became major economic and political drains on the Soviets with Afghanistan being the worst. And their Warsaw Pact allies in Eastern Europe became a severe economic drain and psychic problem.&lt;ref&gt;Mueller and Graves (2023).&lt;/ref&gt; 

President Reagan, inaugurated 1981-01-20, had a very different vision of the role of the US in foreign relations from his predecessor, [[w:Jimmy Carter|Jimmy Carter]]. In 1983-06-21 Reagan insisted, &quot;We cannot permit the Soviet-Cuban-Nicaraguan axis to take over Central America&quot;, because the consequences would include &quot;a tidal wave of refugees ... 'feet people' ... swarming into our country.&quot;&lt;ref&gt;Clines (1983).&lt;/ref&gt; 

Other sources&lt;ref&gt;e.g., Andersen (2006, Part II).&lt;/ref&gt; insist the opposite, that the vast majority of deaths in Central America during the Reagan years were poor humans petitioning nonviolently for a redress of grievances, suppressed by terrorist / death squads supported by the Reagan administration largely in violation of laws passed by Congress and signed by President Reagan. On 1986-10-05 [[w:Corporate Air Services HPF821|a Nicaraguan soldier with a surface to air missile shot down a C-123]] cargo aircraft carrying supplies to the Contra roughly 35 miles (56 km) north of Costa Rica. Documents found in the wreckage and a confession by the sole survivor led to the [[w:Iran–Contra affair|Iran-Contra hearings]] the following year, during which Lt. Col. [[w:Oliver North|Oliver North]] insisted, &quot;We didn't lose the war in Vietnam ..., we lost it in this city.&quot;&lt;ref&gt;Andersen (2006, p. 137). See also, Wikipedia, &quot;[[w:Stab-in-the-back myth|Stab-in-the-back myth]]&quot;, accessed 2026-05-13.&lt;/ref&gt; 

The previous section on the &quot;Gulf of Tonkin Resolution&quot; provides an alternative narrative of the Vietnam War: If as Eisenhower claimed, &quot;possibly 80 per cent of the [Vietnamese] population would have voted for the Communist [[w:Ho Chi Minh|Ho Chi Minh]]&quot; if elections had been held there, it's hard to imagine how anyone else could have won without aggressive action that actually ''improved'' the lives of Vietnamese peasants in the South. US-led efforts there were officially designed to win &quot;[[w:Hearts and Minds (Vietnam War)|Hearts and Minds]]&quot; but were implemented with such coercion that the result was the opposite. A cynic might say that it is hard to win people's hearts and minds by killing them. 

====Richard Barlow and nuclear proliferation====

There is also documentation that the US helped Pakistan get nuclear weapons and destroyed the career of an intelligence analyst, [[w:Richard Barlow (intelligence analyst)|Richard Barlow]], for telling his managers they should not lie to Congress about it. Barlow has insisted that neither Pakistan nor North Korea would have nuclear weapons and Iran would not have a nuclear weapons program today, if the US had followed its own laws. Barlow’s claims, including his punishment by administration officials, have been reported in major media outlets&lt;ref&gt;e.g., Stein (2013). See also Wikipedia, &quot;[[w:Richard Barlow (intelligence analyst)|Richard Barlow (intelligence analyst)]]&quot;, accessed 2026-05-06.&lt;/ref&gt; but not in a way that would seriously limit the ability — and need — for administration officials to lie to Congress. 

If Barlow's claims are accurate, it suggests that US government officials violated US obligations under the [[w:Treaty on the Non-Proliferation of Nuclear Weapons|Non-Proliferation Treaty]] (NPT).&lt;ref&gt;Per the [[w:Treaty Clause|Treaty Clause]] of the US Constitution, a treaty negotiated by the President and approved by the Senate has &quot;the force of federal law.&quot;&lt;/ref&gt; 

==== Nayirah testimony and the 1990-1991 Gulf War ====

A more recent example is the 1990-10-10 testimony by [[w:Nayirah testimony|Nayirah al-Ṣabaḥ to the US Congressional Human Rights Caucus]], two months after the Iraqi invasion of Kuwait. She claimed to have seen Iraqi soldiers taking premature babies out of incubators in a maternity ward before looting the incubators and leaving the babies to die on the floor after the Iraqi invasion of Kuwait; she said she had been a volunteer nurse in the hospital at that time. 

The failure of journalists, including with the ''[[w:NBC Nightly News|NBC Nightly News]]'', to adequate check facts behind this and other atrocity stories helped convince the US public to support the US-led invasion of Iraq in 1990-1991. Nayirah's statements were widely publicized and cited numerous times in the United States Senate and by American president George H. W. Bush to contribute to the rationale for pursuing military action against Iraq. It was later revealed that she was the daughter of Kuwaiti ambassador to the US, [[w:Saud Nasser Al-Saud Al-Sabah|Saud Nasser Al-Saud Al-Sabah]], &quot;Reps. [[w:Tom Lantos|Tom Lantos]] and [[w:John Porter (Illinois politician)|John Edward Porter]], who sponsored the congressional hearings, had started a group called the Congressional Human Rights Foundation that had received $50,000 from Citizens for a Free Kuwait, as well as free office space in [[w:Hill &amp; Knowlton|Hill and Knowlton]]'s Washington headquarters&quot;,&lt;ref&gt;Rowse (1992).&lt;/ref&gt; and the public relations firm Hill and Knowlton had made a video while coaching her rehearsing her perjury and used that to prepare a video press release &quot;that eventually reached a total audience of about thirty-five million&quot;, 14 percent of the [[w:Demographic history of the United States|US population of 249 million per the census then in process]], with portions aired on the ''[[w:NBC Nightly News|NBC Nightly News]]'' the night after the testimony.&lt;ref&gt;Andersen (2006, pp. 170-171).&lt;/ref&gt; 

==== 1998 Embassy bombings and September 11 ====

As another example, there is substantial documentation available today that [[1998 Embassy bombings and September 11|the suicide mass murders of September 11, 2001]], likely would not have occurred if the US had treated the 1998 bombings of the US embassies in Kenya and Tanzania as law enforcement issues. Muslim clerics all over the world initially condemned those acts. Al-Qaeda was dead. Their funding had largely dried up. And bin Laden was scheduled to be extradited the following month to Saudi Arabia to be prosecuted for treason, where he would likely have been convicted and executed. Mayer (2008, p. 114) claimed those embassy bombings were motivated as retaliation for US support for torture.&lt;ref&gt;For more on torture, see the the section on [[#Make media responsible for harms|Make media responsible for harms]] below.&lt;/ref&gt; 

But it seemed questionable at best whether major media executives in the US would have given favorable coverage to such a diplomatic solution. Instead, the US bombed a pharmaceutical plant in Sudan and al-Qaeda training camps in Afghanistan. Then Muslim public opinion turned 180 degrees to conclude, &quot;Bin Laden is right: The US ''is'' an evil empire.&quot; The US became bin Laden’s only indispensable ally, according to the CIA agent responsible for tracking bin Laden at that time.&lt;ref&gt;Scheuer (2004, p. xv).&lt;/ref&gt; Leading Saudis started supporting al-Qaeda, including some working for the Saudi embassy and consulates in the US. Only one country seems to have been involved in the preparations for the September 11 attacks, and that was Saudi Arabia. But Saudis were friends of the Bush family, and a crisis is a terrible thing to waste.&lt;ref&gt;Romer (2009).&lt;/ref&gt; 

:''Did the US invade Afghanistan and Iraq on grounds that senior journalists and leading media executives should have known at the time were questionable and likely fraudulent — to the detriment of nearly everyone except the &quot;people&quot; who control most of the money for the media?'' 
:In particular, was Iraqi president [[w:Saddam Hussein|Saddam Hussein]] really a bigger threat to the US after he invaded Kuwait in 1990 or after the [[w:September 11 attacks|suicide mass murders of September 11, 2001]] than he was during the 1980s, when the US supported him [[w:Iran-Iraq War|killing Iranians]] or [[w:Anfal campaign|his own native Kurds]]? 

On 2003-05-29 [[w:BBC|BBC]] journalist [[w:Andrew Gilligan|Andrew Gilligan]] reported that the [[w:Tony Blaire|Blair government]] had &quot;sexed up&quot; [[w:September Dossier|intelligence reports]] issued the previous September to justify supporting the 2003-03-20 [[w:Iraq War|US-led invasion of Iraq]], two months before Gilligan's report. This led to the [[w:Hutton Inquiry|Hutton Inquiry]], which led to the resignations of Gilligan and the BBC's chairman and the firing of the BBC's director-general. However, the British public expressed so many reservations about the Hutton Inquiry that a follow-up investigation was ordered in 2009. This became the &quot;[[w:Iraq Inquiry|Iraq Inquiry]]&quot;, whose 2016-07-06 report essentially validated what Gilligan had said just over 13 years earlier. This provides one more example of the 1710 maxim of Jonathan Swift that, &quot;Falsehood flies, and truth comes limping after ... like a physician, who hath found out an infallible medicine, after the patient is dead.&quot;&lt;ref name=Swift/&gt;

====Ukraine war====

Page 1 of the 2023-05-04 edition of ''[[w:Le Monde Diplomatique|Le Monde Diplomatique]]'' carried a headline: 

:One year after the invasion of Ukraine: The media, vanguard of the war party,&lt;ref&gt;Halimi and Rimbert (2023) in the French-language original.&lt;/ref&gt;

consistent with Andersen (2006).

=== Make media responsible for harms ===

How might the world be different if injured parties could successfully sue major media for harms that result from government policies contradicted by evidence reasonably available to the major media outlets? 

For example, how might the world be different if: 

* combat veterans or their families could successfully sue major media outlets for biased reporting that stampede the nation into ill advised and counterproductive uses of military force on grounds that leading media personalities should have known at the time were questionable and likely fraudulent? 
* Vietnamese or Afghanis or Iraqis or Palestinians or victims in other countries could win similar lawsuits?
* immigrants could sue major media outlets for failing to publish reasonable summaries of the available research that says that immigrants on average are more entrepreneurial&lt;ref&gt;Aghion et al. (2022, pp. 266-270).&lt;/ref&gt; and no more likely to engage in criminal activities than native born, benefitting both the sending and receiving countries?&lt;ref&gt;The Wikipedia article on &quot;[[w:Immigration|Immigration]] cites research saying, &quot;that migration can be beneficial both to the receiving and sending countries. The academic literature provides mixed findings for the relationship between immigration and crime worldwide. ... [P]ublic perception often exaggerates the connection between immigration and crime, influenced by sensationalised media coverage and political rhetoric.&quot; The Wikipedia article on [[w:Immigration and crime|Immigration and crime]] notes that in some countries immigrants are over-represented in prison populations due to violations of immigration law or anti-immigrant biases in criminal justice. The Wikipedia article on &quot;[[w:Sanctuary city|Sanctuary city]]&quot; says that, &quot;Some studies on the relationship between sanctuary status and crime have found that sanctuary policies either have no effect on crime or that sanctuary cities have lower crime rates and stronger economies than comparable non-sanctuary cities.&quot; All references 2026-05-26.&lt;/ref&gt; 
* humans tortured by the US could sue the major media for suppressing honest discussion of the research that documents that torture is more likely counterproductive? An important report of the efficacy of torture was published in 1631 by [[w:Friedrich Spee|Friedrich Spee]], a German Jesuit priest and professor. A few years earlier, the Duke of Brunswick had invited Spee and another famous Jesuit scholar to supervise a continuation of the torture of a confessed witch. The Jesuits had previously told the Duke, &quot;The Inquisitors are doing their duty. They are arresting only people who have been implicated by the confession of other witches.&quot; The Duke then led the Jesuits to a woman being stretched on the rack and asked her, &quot;You are a confessed witch. I suspect these two men of being warlocks. What do you say? Another turn of the rack, executioners.&quot; &quot;No, no!&quot; screamed the woman. &quot;You are quite right. I have often seen .. . They can turn themselves into goats, wolves ... Several witches have had children by them. ... The children had heads like toads and legs like spiders.&quot;&lt;ref&gt;Pinker (2011, pp. 138-139). Mannix (1964, pp. 134-135). Mackay ( 2009, p. 320).&lt;/ref&gt; Crudely similar comments about the counterproductive nature of torture were made by Generals [[w:Stanley McChrystal|Stanley McChrystal]] (2013) and [[w:David Petraeus|David Petraeus]],&lt;ref&gt;DePaulo (2008).&lt;/ref&gt; who held command positions in Iraq and Afghanistan. The major media in the US has provided ample coverage of, e.g., comments by Donald Trump supporting torture (McCarthy 2016), while largely suppressing honest discussion of the research on it. 

Might the world be safer and more prosperous if major media outlets and their executives and journalists could be successfully sued when their biased reporting have substantive negative consequences? Might [[w:Freedom of information|the public's right to receive diverse information]] be advanced in this way, recognizing that false information disseminated by major media outlets can lead to substantive harms, similar to &quot;[[w:Shouting fire in a crowded theater|shouting ''fire'' in a crowded theater]]&quot;, while the same information disseminated by minor outlets would ''not'' produce such harms? 

Lawsuits of this nature could be facilitated by &quot;group libel&quot; laws. Activists were working to pass such laws in the 1940s. By 1950 those campaigns had been abandoned, according to Barbas (2023).&lt;ref&gt;See also Calvert et al. (2023, pp. 178ff).&lt;/ref&gt; 

[[w:Yael Eisenstat|Yaël Eisenstat]] agrees that under [[w:Section 230|Section 230]] of Title 47 of the US Code, &quot;No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider.&quot; However, Eisenstat insists that [[Online platforms' effects on public health, safety and democracy|&quot;an interactive computer service&quot; ''can'' be held liable when their algorithms have substantive negative consequences]], as in the jury verdicts against Meta in New Mexico&lt;ref&gt;Allyn (2026).&lt;/ref&gt; and against Meta and Google in Los Angeles.&lt;ref&gt;McQue (2026).&lt;/ref&gt; She said, &quot;those technologies, if they are, in the end, contributing to an illegal activity or to harm, that's what we should be addressing. ... The ultimate goal is not to shut down every social media company. The ultimate goal is to figure out what a safer online experience looks like and what accountability looks like when something unsafe happens.&quot;

You, dear reader, can help overcome these problems by talking, as suggested in the exercises below and the rest of this book. If you can help others become less angry and more willing to agree to disagree agreeably with others, that should reduce the risk of war and improve the prospects for progress on other major problems facing humanity today. 

==2. Training in nonviolent noncooperation for anyone willing to listen == 

A major driver of the current conflict between India and Pakistan is mistreatment of Muslims in India. Simulations of a nuclear war between India and Pakistan suggest that such a war would likely produce a nuclear autumn lasting years during which 40 percent of humanity would starve to death if they did not die of something else sooner. Over 90 percent of those would be in countries not involved in the nuclear exchange.&lt;ref&gt;Xia et al. (2022). See also Wikiversity, &quot;[[Responding to a nuclear attack]]&quot;, accessed 2026-05-05.&lt;/ref&gt;

The recent &quot;[[w:2025 India–Pakistan conflict|2025 India–Pakistan conflict]]&quot; was a response by India to violence in Indian-administered [[w:Kashmir|Kashmir]] by terrorists allegedly supported by Pakistan. India would have had much more difficulty justifying violent repression of ''nonviolent'' protests, especially if a more diverse media ecology gave such protests more and more sympathetic coverage. 

During the [[w:Great Depression|Great Depression]], ethnic Germans in the [[w:Sudetenland|Sudetenland]] region of [[w:Czechoslovakia|Czechoslovakia]] were harder hit by increasing trade barriers than their non-German neighbors. They were therefore more open to populist and extremist movements such as fascism, communism and German irredentism.&lt;ref&gt;Wikipedia, &quot;[[w:Sudetenland|Sudetenland]]&quot;, esp. the section on &quot;[[w: Sudetenland#Within the Czechoslovak Republic (1918–1938)|Within the Czechoslovak Republic (1918–1938)]]&quot;, accessed 2026-05-05.&lt;/ref&gt; If those ethnic Germans had used nonviolent noncooperation to highlight their grievances, and if Czechoslovakia at that time had had a substantially more diverse media system, it seems likely that they could have gotten reasonable redress of grievances. If so, it would have been harder for Hitler to use that as an excuse to invade Czechoslovakia, as he did in 1938.&lt;ref&gt;Wikipedia, &quot;[[w:Occupation of Czechoslovakia (1938–1945)|Occupation of Czechoslovakia (1938–1945)]]&quot;, accessed 2026-05-05.&lt;/ref&gt; 

In 1940, during [[w:World War II|World War II]], Germany invade Denmark, which had previously declared neutrality. The Germans allowed [[w:1943 Danish Folketing election|Danish parliamentary elections in 1943]]; the Danish Nazi party won only 2.1% of the votes.&lt;ref&gt;{{cite web|title=Rigsdagsvalgene i Marts og April 1943|url=http://www.dst.dk/pukora/epub/upload/20217/valg1943.pdf|date=|publisher=Danmarks Statistic|accessdate=11 February 2021}}&lt;/ref&gt; When the Nazis ordered the Danes [[w:Rescue of the Danish Jews|to ship their Jews to the death camps, the Danes ignored those orders.]] When the Germans decided to do it themselves, a German diplomat leaked that decision, and nearly all Danish Jews escaped to neutral Sweden; 99% of Denmark's Jewish population survived the Holocaust.

An ideal settlement of the current Russo-Ukraine war might include training in nonviolent noncooperation made more effective through a more diverse media culture as suggested above. A substantial portion of the Ukrainian population, especially the Ukrainian military, are reported to be vicious anti-Russian Nazis, and the Ukrainian government has outlawed many uses of non-Ukrainian languages, especially Russian.&lt;ref&gt;Horton (2024).&lt;/ref&gt; A campaign of nonviolent noncooperation with a vigorous, diverse adversarial press would likely make it harder for Ukraine to continue any persecution of Russian speakers. It would also make it harder for major media in the US and Western Europe to suppress honest discussion of anti-Russian racism in Ukraine. Swanson (2022) said that the [[w:Baltic states|Baltic states]] have implemented such training in preparations for a possible Russian invasion; they might be asked to support such training in Ukraine (and elsewhere).&lt;ref&gt;Swanson (2022).&lt;/ref&gt; 

Organizations offering training in [[w:Nonviolent resistance|nonviolent noncooperation]] include [[w:Nonviolence International|Nonviolence International]] and the [[w:Highlander Research and Education Center|Highlander Research and Education Center]]. 

=== Civil resistance deters fracking ===

Duhamel (2013) claimed that well-advertised planning and training in nonviolent noncooperation helped deter oil companies from attempting hydraulic fracturing in [[w:Quebec|Quebec Province]] in [[w:Canada|Canada]]. Deterring a foreign invasion is different, but the same principle should apply: It's clear from many sources that elites consider nonviolence a threat; it's a felony to teach nonviolence to someone whom the US State Department claims supports a &quot;foreign terrorist organization&quot;, discussed in the next section.  

=== Life in prison for teaching nonviolence ===

Per the US Supreme Court decision in ''[[w:Holder v. Humanitarian Law Project|Holder v. Humanitarian Law Project]]'' (2010), teaching nonviolence to anyone whom the US State Department claims supports a foreign terrorist organization is &quot;[[w:Providing material support for terrorism|providing material support for terrorism]]&quot;, which is a felony under the USA [[w:Patriot Act|Patriot Act]] of 2001. Moreover, if the State Department claims that the death of any &quot;person&quot; resulted from the activities of the designated foreign terrorist organization, the penalty can be life in prison, where &quot;person&quot; is defined in the Patriot Act as &quot;any individual or entity capable of holding a legal or beneficial interest in property&quot;.&lt;ref&gt;The treatment of [[w:Sami Al-Arian|Sami Al-Arian]] is worth noting in discussing the Patriot Act. Al-Arian is a Kuwaiti-born political activist of Palestinian origin, who earned a doctorate in Electrical Sciences and Systems Engineering at [[w:North Carolina State University|North Carolina State]] in 1985 and taught computer engineering at [[w:University of South Florida|University of South Florida]] (USF) beginning in 1986. He was granted permanent resident status in 1989. In 1993 he earned a Distinguished Teacher Award as a tenured associate professor at USF. He was an [[w:imam|imam]] in a local [[w:mosque|mosque]] and led in other initiatives to promote dialogue and public policy initiatives between the West and Middle East. On September 26, 2001, he appeared on ''[[w:The O'Reilly Factor|The O'Reilly Factor]]'' where he was confronted with a 1988 recording of him shouting &quot;death to Israel&quot;. Al-Arian replied that &quot;Death to Israel&quot; meant &quot;death to occupation, ... apartheid, ...oppression,&quot; whereupon O'Reilly cut him off and called for the [[w:Central Intelligence Agency|Central Intelligence Agency]] to investigate him. Al-Arian spent most of the next 14 years between that 2001 interview and 2015 in detention, much of it in solitary confinement. This period included a 2005 trial that ended with acquittal on 8 counts and a hung jury on another 9. In 2015 he was deported to Turkey. In 2017, he founded the Center for Islam and Global Affairs at [[w:Istanbul Sabahattin Zaim University|Istanbul Sabahattin Zaim University]] in Istanbul, Turkey, which he directs. What has been the impact of treatment of Al-Arian on the well-being of the bottom 99 percent of the US and world population?&lt;/ref&gt; 

How did these provisions get written into the Patriot Act? 

That's a question that deserves research, perhaps by asking elected officials in the US Congress and lobbying for their repeal. A speculation consistent with the thesis of this book is that nonviolence terrifies those who control most of they money for the media, because it threatens their ability to get their security forces to follow orders.

==3. Forbid uses of force beyond one’s own borders and covert interference in foreign countries ==

:''[[w:Si vis pacem, para bellum|If you want peace, prepare for war.]]''
:  -- ''[[w:De Re Militari|De Re Militari]]'' by [[w:Publius Flavius Vegetius Renatus|Publius Flavius Vegetius Renatus]] (fourth or fifth century AD)

The record of history is now clear: Those who prepared for war often got war initiated when one party claimed they were being attacked or about to be attacked and believed they would fare better by attacking. Sometimes this occurred when the media environment convinced leaders that their political futures required them to clandestinely provoke foreign entities to do things that could then be denounced as unprovoked to justify military escalation, as mentioned in the previous section.  

Samuelson (2025) summarized quantitative analyses of 60 insurgencies since World War II, whose findings included the complete absence of success with counterinsurgencies without large force ratios (at least four, and most often more than ten, times the force of the insurgents) and without &quot;providing a path toward peaceful addressing of grievances&quot;. He also noted that, &quot;Brutality toward the civilian population ... tends to inflame the insurgency.&quot;&lt;ref&gt;Samuelson (2025) summarized Lawrence (2015).&lt;/ref&gt; His analysis gave a pessimistic prognosis for the [[w:Gaza war|Gaza war]] that began 2023-10-07. His conclusions are consistent with the history of the current [[w:Russo-Ukrainian war|Russo-Ukrainian war]], the [[w:Vietnam War|Vietnam War]], the [[w:Graveyard of empires|First, Second, and Third Anglo-Afghan Wars (1839-1919), the Soviet-Afghan War (1979–1989), the US-led War in Afghanistan (2001–2021)]], the 2001-2011 [[w:Iraq War|Iraq War]], and others. 

A key point is that invaders often to lose unless they enter with overwhelming force like Germany in the early stages of World War II: The [[w:Occupation of Czechoslovakia (1938–1945)|Czechoslovaks]], [[w:Invasion of Poland|Poles]], [[w:France during World War II|French]], and others were not prepared to fight the Germans, but the [[w:Soviet Union in World War II|Soviets]] were. [[w:Adolf Hitler|Hitler]] doubtless knew that the [[w:Switzerland during World War I and World War II|Swiss]] were prepared to fight, so he attacked other countries first. While fighting the [[w:Russo-Ukrainian war#Full-scale Russian invasion of Ukraine (2022)|Russian invasion]] that began 2022-02-24, [[w:Defense industry of Ukraine|Ukraine has developed]] military drones that are highly effective relative to the cost, as witnessed by sales of such to Gulf Arab states,&lt;ref&gt;Sharawi and Shapiro (2026).&lt;/ref&gt; illustrating the point that foreign invaders often encounter vastly more resistance than they expect -- and should expect highly effective resistance if they invade a country prepared to fight on their own territory. 

The rest of this section discusses weaknesses with standard deterrence theory. 

===Deterrence theory and nuclear Armageddon=== 

Standard [[w:Deterrence theory|deterrence theory]] assumes that one's opponents are rational and do not want [[w:Armageddon|Armageddon]]. The record of history summarized above raises questions about this assumption: In World War I, even the &quot;winners&quot; arguably lost more than they gained -- doubtless excepting a few merchants, who made fortunes from what they sold. Many of the other military decisions discussed above seem to have been driven more by the media than military necessity. 

Beyond that, at least some portions of the [[w:Islamic State|Islamic State]] reportedly violates this assumption, because it &quot;not only believes in the literal meaning of the coming Armageddon – it sees itself as its chief protagonist.&quot;&lt;ref&gt;Misra (2015).&lt;/ref&gt; Some [[w:Christian nationalism|Christian nationalists]] promoted to command positions by [[w:United States Secretary of Defense|US Secretary of Defense]] [[w:Pete Hegseth|Hegseth]] and President Trump also seem to believe that Armageddon might be desirable. On 2026-03-03 the [[w:Military Religious Freedom Foundation|Military Religious Freedom Foundation]] said they had received over 200 complaints from over 50 different US military installations with comments like, &quot;President Trump has been anointed by Jesus to light the signal fire in Iran to cause Armageddon and mark his return to Earth&quot;, per an email from one [[w:Non-commissioned officer|NCO]].&lt;ref&gt;Nick Mordowanec (2026).&lt;/ref&gt; With Hegseth holding monthly Christian worship services in the Pentagon during business hours,&lt;ref&gt;Black (2025), Mayes-Osterman (2025). See also the section on &quot;[[w:Pete Hegseth#Pentagon Christian worship services and &quot;biblically sanctioned war&quot;|Pentagon Christian worship services and &quot;biblically sanctioned war&quot;]] in the Wikipedia article on [[w:Pete Hegseth|Pete Hegseth]], accessed 2026-05-14.&lt;/ref&gt; this suggests that Hegseth could have appointed enough Christian nationalists to key positions to initiate nuclear attacks on Iran or Russia, claiming that President Trump had ordered such whether he had or not.&lt;ref&gt;The [[w:Gold Codes|Gold Codes]] carried in the &quot;[[w:nuclear football|nuclear football]]&quot; required by the [[w:Permissive action link|permissive action link]]s would ''not'' prevent Hegseth and a few others appointed by him from initiating nuclear Armageddon, according to Ellsberg, who had been a nuclear war planner for presidents Eisenhower, Kennedy, Johnson, and Nixon, before releasing the ''[[w:Pentagon Papers|Pentagon Papers]]''. Ellsberg (2017, p. 69) insisted that the security provided by those Gold Codes were a hoax, because otherwise a single nuclear detonation on Washington, DC, when both the president and vice president were in town &quot;would would definitively block any authorized, coordinated nuclear response to that or any subsequent nuclear attack.&quot;&lt;/ref&gt; 

The biggest risk today may be the risk of [[w:Nuclear holocaust|nuclear Armageddon]], which seems on average to grow over time consistent with experience with &quot;[[w:system accidents|system accidents]]&quot; in other fields: It is naive to assume that any system as complex as military command, control and communications systems never fail. And managers of complex systems subject to rare, catastrophic failures &quot;learn&quot; from experience that they can take ever greater risks, because they have &quot;safely&quot; done so in the past — until there is a catastrophe:&lt;ref&gt;Kahneman and Klein (2009) found that expert intuition, when it exists, is learned from frequent, rapid, high quality feedback. With anything nuclear, mishaps are so rare that managers develop &quot;expert intuition&quot; that they can &quot;safely&quot; ignore safety concerns -- until there is a catastrophe. See also Sagan (1993).&lt;/ref&gt; 

Veterans for Peace (2022) recommend global reduction and rapid elimination of nuclear weapons &quot;to reduce the real risk of nuclear confrontation through accidental launch or miscalculated escalation&quot;. 

==== National security tariffs ====

Free trade agreements supported by the [[w:World Trade Organization|World Trade Organization]] allow exemptions for national security and other objectives. [[Responding to a nuclear attack|Even a minor nuclear war between India and Pakistan would have a negative impact on the entirety of humanity]]. It might therefore be sensible for parties to the [[w:Treaty on the Prohibition of Nuclear Weapons|Treaty on the Prohibition of Nuclear Weapons]] (TPNW) to institute gradually increasing tariffs on nuclear weapon states, not so great as to seriously impact the economy of the nation applying such tariffs but aggressive enough to gradually wean their economy from reliance on trade with nuclear-weapon states that refuse to support the TPNW. 

See also the chapter below on [[/Media Literacy and You/Responding to a nuclear attack/|Responding to a nuclear attack]]. 

===Research on the effectiveness of deterrence and implications=== 

Lebow and others have provided substantial documentation of case studies claiming that leaders are often not rational, and deterrence based on threatening use of military force beyond one’s own borders has been ''as likely to provoke as prevent'' undesired behavior.&lt;ref&gt;Lebow (2025, 2024), Lebow et al. (2023).&lt;/ref&gt; The most obvious portions of this threat can be entirely eliminated by policies clearly and effectively forbidding use of force beyond one’s own borders. This can be signaled in at least three ways: 

* Eliminate all weapon systems like missiles and aircraft with a range of more than, e.g., a hundred miles or 200 kilometers with the possible exception of surveillance only aircraft that cannot be easily configured to carry [[w:Materiel#Military|ordnance]], e.g., explosives. Similarly eliminate nuclear weapons, which few if any countries would want to use for military defense inside their own borders. 

* Supply a national guard and reserves with weapons, training, and rules of engagement that prohibit projecting force beyond one’s own borders. Train them also in development and use of improvised explosive devices and other tactics and devices like low cost military drones. 

:Afghanistan is said to be the &quot;[[w:Graveyard of empires|Graveyard of empires]]&quot;. They defeated the British three times (1839–1842, 1878–1880, 1919), the Soviet Union (1979–1989), and the US (2001–2021). Each victory came with foreign supplies, but any foreign troops helping Afghanis were primarily under the command of local leaders. 
:The [[w:2003 invasion of Iraq|2003 invasion of Iraq]] might have produced [[w:Nation-building|nation-building]] more like the experience of [[w:Nation-building#Germany and Japan after World War II|Germany and Japan after World War II]] if the US had mandated a vigorous adversarial press instead of strict censorship, according to McChesney and Nichols.&lt;ref&gt;McChesney and Nichols (2010, Appendix II. Ike, MacArthur and the Forging of Free and Independent Press, pp. 241-254).&lt;/ref&gt; This claim by McChesney and Nichols was not endorsed by [[News from Germany 1900-1945 and implications for today#After the war in Germany vs. Iraq|University of British Columbia History professor Heidi Tworek]], who said the democratization efforts in Germany and Japan after World War II were more complicated than that implied by that brief discussion by McChesney and Nichols.&lt;ref&gt;The 2025-07-03 interview with Tworek is available at &quot;[[News from Germany 1900-1945 and implications for today]]&quot;, accessed 2026-05-14.&lt;/ref&gt; However, the research by Usher and Kim-Leffingwell (2022) and the related research on news deserts summarized in the preface to this ''[[Media Literacy and You]]'' book largely supports those claims by McChesney and Nichols.
:[[w:Defense industry of Ukraine|Ukraine has become a world leader in military drones]], many of which are dramatically cheaper than alternatives. Most of those have limited range but have been useful for reconnaissance and delivery of ordnance and improving targeting of, e.g., surface to air missiles. 
:[[w:Eliot A. Cohen|Eliot Cohen]], who served as a special advisor to [[w:United States Secretary of State|US Secretary of State]] [[w:Condoleezza Rice|Condoleezza Rice]] from 2007 to 2009, wrote, &quot;As the United States discovered in Iraq and Afghanistan, no matter how large, technologically advanced, and proficient an army is, motivated insurgents can still inflict casualties in the tens of thousands.&quot;&lt;ref&gt;Cohen (2022), cited from Horton (2024, p. 1026).&lt;/ref&gt; Cohen recommended we &quot;Arm the Ukranians now&quot;. Horton said that the neoconservatives learned from Iraq War II and Afghanistan that the US &quot;should fight like those who defeated them.&quot;&lt;ref&gt;Horton (2024, p. 1026).&lt;/ref&gt; 
:Leading economist [[w:Jeffrey Sachs|Jeffrey Sachs]] addressed the European Parliament 2025-02-19, claiming that the tragedy that befell Serbia in 1999 and subsequent US uses of force in Iraq and Syria, plus wars in Africa including Syria, Somalia and Libya and the current wars in Ukraine and the Israel-Hamas war, &quot;are to a very significant extent the result of deeply misguided US policies.&quot;&lt;ref&gt;Sachs (2025-02).&lt;/ref&gt; He said that Europe should craft its own foreign and military policies, independent of the US. ''[[w:Le Monde Diplomatique|Le Monde Diplomatique]]'' noted that Sachs' speech has circulated among social media since ''but has yet to be seriously discussed by major European media.''&lt;ref&gt;Sachs (2025-04; emphasis added).&lt;/ref&gt; 

* Change the laws of government secrecy so government officials cannot secretly interfere in the internal affairs of foreign countries or otherwise project force outside their own borders. This might be achieved in the US in part by requiring anyone with information about questionable actions by government officials to provide such documentation to one or more congressional oversight bodies while also allowing any current or former government employee or contractor to file suit in any US federal jurisdiction if they feel they have been punished for refusing to support questionable activities. In addition, federal judges should be authorized to subpoena classified government documents that may be relevant to any case in their jurisdiction and declassify them subject to appellate review if they believe the national interest would be better served by declassification. 

:If the law is changed without a substantive [[#1. Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content.|citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference]], as discussed above, the change could be merely cosmetic and unconvincing to local public officials and potential adversaries. 
:Connelly (2023) noted that US government secrecy has in the past encouraged administration officials to do things to provoke actions by foreign entities that can then be denounced as “unprovoked” to stampede the US Congress and the public into supporting counterproductive uses of military force, as discussed above.&lt;ref&gt;See also Connelly et al. (2023).&lt;/ref&gt; A more diverse media culture should make it harder for administration officials to lie to the public and to Congress — and harder to punish government employees who tell their managers that they should not lie to Congress, as they reportedly did to [[#Richard Barlow and nuclear proliferation|Richard Barlow]], mentioned above. 
:The Barlow case and many others explain why the US should, e.g., give federal judges the authority to subpoena classified documents and declassify them if they believe the public good is better served from declassification than continued secrecy.&lt;ref&gt;See, e.g., the 2025-05-08 interview with Seth Stern and Lauren Harper discussing what the &quot;[[Freedom of the Press Foundation says...]]&quot;, Graves (2014), and [[w:Moynihan Commission on Government Secrecy|Moynihan Commission on Government Secrecy]], accessed 2026-05-06. Graves (2021) recommends &quot;Congressional Gold Medals for&quot; Barlow and whistleblowers.&lt;/ref&gt; 

These policies would make it hard for any foreign leader to justify an attack for multiple reasons: First, it would be difficult to convince their supporters that such an attack is necessary. Second, a rational foreign leader might be hesitant to invade a country that is prepared to fight a guerrilla war. Germany reportedly considered invading [[w:Switzerland during World War I and World War II|Switzerland during both World Wars I and II]] and decided against it in part because Switzerland had large, well-trained ready reserves, who were ready to fight. Belgium seemed to be an easier route.&lt;ref&gt;Documented in Wikipedia, &quot;[[w:Switzerland during World War I and World War II|Switzerland during World War I and World War II]]&quot;, accessed 2026-05-06. Switzerland also has many mountains, which make it easier to defend, but the capabilities of the Swiss military also influenced the German decision to avoid Switzerland.&lt;/ref&gt; Third, even if foreign invaders defeat the guerrillas, they should not assume that their invading forces would continue to follow orders. [[w:Rescue of the Danish Jews|Ninety-nine percent of Danish Jews reportedly survived World War II]] because of Danish noncooperation ''supported by a German diplomat''.&lt;ref&gt;Wikipedia, &quot;[[w:Rescue of the Danish Jews|Rescue of the Danish Jews]]&quot;, accessed 2026-05-06.&lt;/ref&gt; 

With policies like these in place, it would be hard for foreign leaders to convince their supporters of a need to attack, as [[w:2022 Russian invasion of Ukraine|Putin did when invading Ukraine in 2022]],&lt;ref&gt;The Wikipedia article on &quot;[[w:2022 Russian invasion of Ukraine|2022 Russian invasion of Ukraine]]&quot;, accessed 2026-05-06, includes a paragraph saying, 'In July 2021, Putin published an essay &quot;On the Historical Unity of Russians and Ukrainians&quot;, in which he called Ukraine &quot;historically Russian lands&quot; and claimed there is &quot;no historical basis&quot; for the &quot;idea of Ukrainian people as a nation separate from the Russians&quot;'. Putin was accused of promoting Russian imperialism, historical revisionism and disinformation. Writing in 2024, Michael McFaul and Robert Person described this essay as representing not only &quot;cynical propaganda&quot; but also Putin's &quot;deeply held and internalized beliefs&quot;. See the Wikipedia article for references supporting those claims.&lt;/ref&gt; as [[w:2025 India–Pakistan crisis|India did when attacking Pakistan in 2025]], and as [[w:Invasion of Poland|Hitler did when invading Poland in 1939]], to name only three examples. 

=== If we continue to base deterrence on threats === 

There are now calls for Europe to get their own nuclear weapons,&lt;ref&gt;Burgard (2025).&lt;/ref&gt; while Iran, Saudi Arabia, Turkey, South Korea and Taiwan have been suggested as other candidates for acquiring nuclear weapons should they feel a sufficient need.&lt;ref&gt;Ruehl (2024).&lt;/ref&gt; 

It is difficult to imagine how the number of nuclear weapon states could be increased without increasing the risks of a nuclear war, consistent with the discussion of &quot;[[w:system accident|system accident]]s&quot; earlier in this chapter.

Secondarily, intelligence services with information on political corruption including attempts to intimidate and murder journalists should not be allowed to keep that information secret: They should be required to find ways to leak that information to journalists. Such attacks on journalists in their own country should be exposed and prosecuted if the evidence seems likely to obtain a conviction. Intelligence services with information about such attacks in other countries should be required to find ways to leak it to competent journalists without identifying their sources and methods: Doing so would likely reduce political corruption worldwide and with that the risks of war. 

== Collateral damage ==

The research cited above supports the claim that, 

:''[[w:Collateral damage|Collateral damage]] that our designated enemies commit prove to us that they are subhuman or criminally misled.''
:''Meanwhile, collateral damage that we commit is unfortunate but necessary -- from our perspective. However, it proves to our designated enemies that we are subhuman or criminally misled.'' 

This observation supports this entire program of deterrence without threat: 
* Forbidding use of force beyond one’s own borders and covert interference in foreign countries would automatically reduce collateral damage. It would also avoid uses of force that seem not to contribute to broadly shared peace and prosperity, according to research cited above. 
* The effectiveness of nonviolent noncooperation rests in part on its near universal avoidance of collateral damage. 
* Citizen-directed subsidies for local news nonprofits with firewall(s) to prevent political interference in the content should make it much harder for major media to convince the public to do things contrary to their best interests, like invading or interfering covertly in foreign countries. 

== Call for help == 

Do you, dear reader, know other serious research not cited herein that might improve this analysis? If yes, you can help improve this discussion by adding comments with citations -- or by adding such citation(s) to the &quot;Discuss&quot; page associated with this chapter, suggesting someone else revise the chapter appropriately. 

There are plenty of contrary claims in the major media, but the lead author of this chapter is not aware of any that are based on serious research. 

In the absence of such research, the current author finds it difficult to imagine any national defense policies that carry a greater risk of nuclear Armageddon than our current policies, as discussed in the next chapter of this book on ''[[Media Literacy and You]]'' on &quot;[[Media Literacy and You/Responding to a nuclear attack|Responding to a nuclear attack]]&quot;. That chapter, in sum, claims that the ''worst'' response to a nuclear attack would be nuclear response, because it would escalate a catastrophe killing millions of humans to one killing ''billions'', possibly 80 percent of humanity in a war between the US and Russia that lofts so much smoke from burning cities to the stratosphere where it covers the globe depressing crop yields for years during with 99 percent of the humans in the US, Europe and Russia would starve to death if they did not die of something else sooner. Moreover, the record of &quot;[[w:System accident|system accident]]s&quot; suggests that the chances of such a war before the end of this century is substantially greater than the 40 percent median estimate based on history mentioned in a presentation on &quot;[[Time to nuclear Armageddon]]&quot; delivered to the 2019 Joint Statistical Meetings. 

This chapter is being written in the hopes of inspiring action to improve the prospects for broadly shared peace and prosperity for the long term. 

== Exercises ==

1. Disconfirmation bias: Brainstorm your biggest concerns about a current or possible future war. 
:1.1. Select the one that is of greatest concern to you currently. 
::One issue that may not be a major concern for many but might elicit a broad consensus for action would be a campaign to ask elected officials in the US Congress to explain how we benefit from the provisions of the USA Patriot Act of 2001 that authorize [[#life in prison for teaching nonviolence|life in prison for teaching nonviolence]]. 
:1.2. Who are your designated enemies? 
:1.3. Research what your designated enemies are saying about your biggest concern.  
:1.4. Under what circumstances would you support what you see your designated enemies advocating or doing? 
::If you cannot see such circumstances, expand your research: Look for more sources that support your designated enemies. 

2. Interacting: Ask others if you can share what you've learned about that conflict. If they say, &quot;No&quot;, don't push it. If they agree, share what you've learned in a friendly supportive manner without saying that anything is &quot;true&quot;. 

::''Show me someone who knows the truth, and I will show you someone who is dangerous.''

:2.1. The primary goal in this is ''not'' to convince anyone that you are right and they are wrong but to lower the level of anger and increase the level of tolerance for dissenting views. 
:2.2. Another goal is to comfortably enjoy civil conversations of this nature, agreeing to disagree agreeably and building trusting relationships that support collaboration on issues of common concern. 
:2.3. After becoming adept at building collaborations on issues of common concern, you might consider teaching this important skill and approach to issues.  

3. Teaching: Each one teach two, as discussed in the section on &quot;[[Media Literacy and You#Text and self-help book and point of discuss|Text and self-help book and point of discuss]]&quot; in the preface to this book.

= The Ignorant Observer Framework =

''This research page is authored and maintained by [[User:IgnorantObserver|Aernoud Dekker]], an independent researcher and the originator of the framework described below. Page text is offered for review, critique, and collaborative refinement under [[Wikiversity:Copyrights|Wikiversity's standard licence]].''

== Status ==

Research project under active development. The framework is an interlinked set of technical and interpretive documents published at [https://ignorantobserver.xyz ignorantobserver.xyz] and archived on the [https://osf.io Open Science Framework]. ''The Ignorant Observer'' is the foundational paper. ''Where Did the Measurement Basis Come From?'' is the conceptual bridge that states, for a physics reader, exactly what claim the framework makes about the measurement basis. ''Bandwidth-Limited Quantum Control'' (BLQC) is the operational layer: a finite-rate phase-reference control law and its laboratory benchmark. ''A Capacity-Calibrated Protocol for Testing Penrose Objective Reduction'' applies that benchmark as the calibration arm of a test of gravitational collapse. A companion paper, ''The Born Rule from Finite Observation'', derives the binary Born form conditionally from finite-record geometry, and a no-go companion marks where that route stops. All work is single-authored.

'''Where the framework stands (July 2026).''' IOF is an interpretation of quantum mechanics, not a rival to it. Its central empirical claim was once sharpened to a testable form — that finite basis tracking produces an ''unrecoverable'' visibility loss, a genuine deviation from standard quantum mechanics — and that strong reading was found to be '''excluded by existing experiments'''. What survives is a no-world-collapse interpretation carrying a ''recoverable'', calibrated control-theoretic subtheory. Everett is the preferred host developed in the corpus, but not an exclusive one; scoped single-history and pilot-wave hosts remain possible. This page raises the strong reading and states its exclusion rather than asserting it.

== One-sentence thesis ==

Quantum measurement normally treats the basis as if it came from outside physics. The Ignorant Observer Framework treats the basis as a finite physical reference variable generated and tracked inside the apparatus itself — and reads quantum randomness as an observer-side appearance of bounded access, while the host supplies quantum phase and cross-context coherence.

== What kind of claim this is ==

The framework has three layers, kept deliberately in separate books and adjudicated by different standards. Confusing them is the most common misreading, so they are named up front.

* '''Operational layer''' (classical, measurable). The deficit κ = ''h''&lt;sub&gt;θ&lt;/sub&gt; − ''C''&lt;sub&gt;eff&lt;/sub&gt; ln 2 is a calibrated control law for the visibility of ''unconditioned'' records. Here ''h''&lt;sub&gt;θ&lt;/sub&gt; is the source-side instability rate relevant to tracking the designated basis coordinate θ; it equals the full Kolmogorov–Sinai rate ''h''&lt;sub&gt;KS&lt;/sub&gt; only in a one-effective-positive-mode source or when a projection result or coordinate-level calibration licenses that identification. Confirming the law '''benchmarks the apparatus; it does not discriminate IOF from quantum mechanics'''. Its hallmark is ''recoverability'': the lost contrast returns when the realised reference is supplied.
* '''Foundations layer''' (structural reconstruction). A conditional derivation obtains the binary Born weight ''p''(θ) = cos²(θ/2) from finite-record geometry under two named bridge assumptions and extends it, through hierarchical binary discrimination, to one calibrated finite-outcome context. A companion no-go theorem shows that the same route cannot generate quantum phase or cross-context composition. This is a reconstruction, not an independent empirical prediction — a constant Fisher information ''I''(θ) is itself a standard-quantum prediction, so the test of the bridge premise is a consistency check.
* '''Interpretation layer''' (the framework's identity). IOF adds no ontic collapse or stochastic selection. In the preferred Everettian host all outcomes occur; in scoped single-history hosts one outcome occurs without an IOF-added random selector. In either case apparent collapse is a record-relative information update, and randomness is the name a finite observer gives to an outcome whose determining dependencies it cannot resolve. The binary Born form is reconstructed on the finite-record side; phase and cross-context coherence remain host-side.

Because the framework as a whole reproduces standard quantum mechanics, it is '''not falsifiable as a whole — by design, not by evasion'''. Its falsifiable content is modular and named: the operational control law (with the caveat that a failure there indicts the apparatus model and the calibration of ''C''&lt;sub&gt;eff&lt;/sub&gt; and ''h''&lt;sub&gt;θ&lt;/sub&gt; before it indicts the framework); the Fisher-homogeneity premise of the Born bridge (exposed in the falsifying direction only); and a registered chaotic-corner module carried with the prior strongly against it.

== Core question ==

''When the classical degrees of freedom that define a measurement basis generate task-relevant information faster than the apparatus can track it, do the apparatus's raw, unconditioned records lose interference contrast on a schedule set by the deficit'' κ = ''h''&lt;sub&gt;θ&lt;/sub&gt; − ''C''&lt;sub&gt;eff&lt;/sub&gt; ln 2 ''— and is that loss recoverable by conditioning on a log of the realised reference?''

The framework's answer is yes to both, and the second half is the point. The loss is reference-frame physics ''within'' quantum mechanics, not a new channel beyond it: standard quantum mechanics already says that records taken against a blurred reference lose contrast, and recovers that contrast once the reference is restored. IOF's contribution is to make the blur a calibrated, controllable quantity — a number a laboratory can dial up and down.

== The strong reading, and why it was excluded ==

A bolder reading of the same formula would make the visibility loss ''unrecoverable'': a capacity-dependent suppression that no offline log could undo — that is, a measurable deviation from standard quantum mechanics. Sharpened, that reading requires the unresolved basis not to imprint on the records (a Markov condition giving a recovery statistic ''R''&lt;sub&gt;rec&lt;/sub&gt; ≈ 0).

Existing experiments exclude it. Logged-setting Bell tests recover the full quantum correlation when the realised settings are recorded and the data are sorted offline (Weihs et al. 1998); randomized-measurement tomography and classical shadows choose observables ''after'' measurement and reconstruct the quantum state (Huang, Kueng &amp; Preskill 2020); correlation spectroscopy recovers coherence beyond the laser linewidth from cross-records. In every case the lost contrast comes back — ''R''&lt;sub&gt;rec&lt;/sub&gt; ≈ 1 up to ordinary imperfections. The suppression is phase averaging over an unresolved reference, not a new physical channel; IOF's own diffusive formula correctly describes the ''raw, unconditioned'' signal, and the recovery is what reveals it as bookkeeping. The framework therefore raises the strong reading and excludes it; it does not claim it.

One corner remains formally open, and is registered rather than asserted: recoverability under ''certified deterministic-chaotic'' basis dynamics has not been directly tested. It is carried in the protocol with the prior strongly against any difference from the diffusive case, and a positive there would overturn the corpus's own exclusion, not confirm a surviving claim.

== Technical proposal ==

The framework introduces the following quantities.

'''Effective channel capacity ''C''&lt;sub&gt;eff&lt;/sub&gt;''' (bits/s): the information rate available to the basis-tracking control loop, operationalised as
:''C''&lt;sub&gt;eff&lt;/sub&gt; = ''r'' · ''b'' · ''f''
with ''r'' the update rate (Hz), ''b'' the effective bits per update that constrain the basis variable θ, and ''f'' ∈ (0,1] the fraction of updates that genuinely constrain θ after overhead and latency. ''C''&lt;sub&gt;eff&lt;/sub&gt; is ultimately bounded by the Landauer limit on the controller's irreversible bookkeeping,
:''C''&lt;sub&gt;eff&lt;/sub&gt; ≤ ''P'' / (''k''&lt;sub&gt;B&lt;/sub&gt; ''T'' ln 2),
but this is a thermodynamic ceiling, not the operating point: realised ''C''&lt;sub&gt;eff&lt;/sub&gt; is typically far lower and must be calibrated as ''useful'' information actually constraining θ, since added power can equally couple to actuator noise or backaction channels that do not constrain the basis.

'''Task-relevant source rate ''h''&lt;sub&gt;θ&lt;/sub&gt;''' (nats/s): the instability or information-production rate that actually burdens tracking of the designated basis coordinate θ. It is source-side, not the entropy of the observer. The full Kolmogorov–Sinai rate ''h''&lt;sub&gt;KS&lt;/sub&gt; is the source's uncertainty-volume production rate and equals ''h''&lt;sub&gt;θ&lt;/sub&gt; only in a one-effective-positive-mode reduction or under an explicit projection result or coordinate-level calibration. The nats/s convention lets κ combine ''h''&lt;sub&gt;θ&lt;/sub&gt; and ''C''&lt;sub&gt;eff&lt;/sub&gt; ln 2 in consistent units.

'''Self-ignorance rate κ''' (s&lt;sup&gt;−1&lt;/sup&gt;):
:κ = ''h''&lt;sub&gt;θ&lt;/sub&gt; − ''C''&lt;sub&gt;eff&lt;/sub&gt; · ln 2
with two regimes. When κ &lt; 0 (''capacity-wins''), basis-tracking error stays bounded and standard quantum visibility is recovered, modulo ordinary decoherence. When κ &gt; 0 (''chaos-wins''), '''standard quantum mechanics still holds''' — nothing new happens to the world — but the observer's reference is no longer fully resolved, and the variance of the basis-tracking error grows as σ&lt;sub&gt;θ&lt;/sub&gt;&lt;sup&gt;2&lt;/sup&gt;(''t'') = σ&lt;sub&gt;0&lt;/sub&gt;&lt;sup&gt;2&lt;/sup&gt; e&lt;sup&gt;2κ''t''&lt;/sup&gt;, so the ''raw, unconditioned'' records lose contrast.

'''Measured visibility and fringe phase'''. For an arbitrary logged tracking-error distribution, the exact reference factor is the circular phasor
:''G''&lt;sub&gt;ref&lt;/sub&gt;(''t'') = E[e&lt;sup&gt;−iδθ(t)&lt;/sup&gt;].
Its magnitude predicts the visibility multiplier and its argument predicts the fringe displacement. Only when the centered Gaussian or wrapped-Gaussian gate passes does this reduce to
:|''G''&lt;sub&gt;ref&lt;/sub&gt;(''t'')| = exp(−½ σ&lt;sub&gt;θ&lt;/sub&gt;&lt;sup&gt;2&lt;/sup&gt;(''t'')),
and, over the registered pre-wrapping range where σ&lt;sub&gt;θ&lt;/sub&gt;&lt;sup&gt;2&lt;/sup&gt;(''t'') = σ&lt;sub&gt;0&lt;/sub&gt;&lt;sup&gt;2&lt;/sup&gt;e&lt;sup&gt;2κ''t''&lt;/sup&gt;, to the double-exponential submodel ''V''(''t'') = exp(−½σ&lt;sub&gt;0&lt;/sub&gt;&lt;sup&gt;2&lt;/sup&gt;e&lt;sup&gt;2κ''t''&lt;/sup&gt;). Variance alone does not determine visibility for a general residual distribution.

'''Reference and baseline visibility'''. When the reference error is separable from the baseline coherence channel, the observed visibility factorises as ''V''&lt;sub&gt;obs&lt;/sub&gt; = ''V''&lt;sub&gt;std&lt;/sub&gt;|''G''&lt;sub&gt;ref&lt;/sub&gt;|. If reference error correlates with baseline coherence, detector acceptance, or geometry, this product is not licensed and the registered joint per-shot model must be used. The reference contribution is recoverable when the realised reference is supplied and may otherwise be misassigned to ordinary decoherence.

'''Breakdown time ''t''&lt;sub&gt;break&lt;/sub&gt;'''. For a chosen visibility threshold ''V''*,
:''t''&lt;sub&gt;break&lt;/sub&gt; = (1 / 2κ) · ln(−2 ln ''V''* / σ&lt;sub&gt;0&lt;/sub&gt;&lt;sup&gt;2&lt;/sup&gt;),    κ &gt; 0.
''t''&lt;sub&gt;break&lt;/sub&gt; is the operational layer's primary observable.

The benchmark uses a one-effective-mode reference source, for which ''h''&lt;sub&gt;θ&lt;/sub&gt; = ''h''&lt;sub&gt;KS&lt;/sub&gt;. Beyond that reference model, identifying a scalar tracking rate with the full ''h''&lt;sub&gt;KS&lt;/sub&gt; requires a separate projection result or coordinate-level calibration (see [[#Open review targets|Open review targets]]).

== The operational benchmark and the Penrose test ==

The experimental layer has two roles, and keeping them apart is essential: an operational ''benchmark'' that calibrates the apparatus, and a ''discrimination'' arm that tests gravitational collapse. Neither tests IOF against quantum mechanics.

'''The benchmark (calibration arm).''' First calibrate the complete estimator/controller chain and its useful timely capacity in a reference-only arm, then freeze that calibration before quantum outcomes. Vary ''C''&lt;sub&gt;eff&lt;/sub&gt; through a preregistered delivery schedule at clamped temperature, readout signal-to-noise, latency, actuator behaviour, and mass geometry. The prediction is that the raw-record breakdown time moves with κ = ''h''&lt;sub&gt;θ&lt;/sub&gt; − ''C''&lt;sub&gt;eff&lt;/sub&gt; ln 2. The distribution-free prediction is the trajectory-conditioned complex phasor; the double-exponential curve is used only after its Gaussian and dynamic-range gates pass. Confirmation benchmarks the instrument within standard quantum mechanics; failure indicts the apparatus model or calibration before it indicts the framework.

'''The recoverability classifier.''' The decisive operational quantity is the recovery statistic ''R''&lt;sub&gt;rec&lt;/sub&gt;: condition the raw records on a passive, full-resolution shadow log of the realised reference and ask whether the lost contrast returns. ''Recoverable'' (''R''&lt;sub&gt;rec&lt;/sub&gt; → 1) is reference-frame physics — the framework's own expected case, in the lineage of quantum reference frames (Bartlett, Rudolph &amp; Spekkens 2007). ''Unrecoverable'' loss is decoherence-type or collapse-type. The classifier is what separates the framework's subject from everything that is not its subject.

'''The discrimination arm — a test of Penrose, not of IOF.''' With tracking held at maximal capacity and the engineered channel quiet, sweep mass geometry and look for a κ-independent, ''unrecoverable'' visibility floor — the signature of gravitational [[w:Penrose interpretation|objective reduction]] (OR), whose timescale ''τ''&lt;sub&gt;OR&lt;/sub&gt; ≈ ℏ/''E''&lt;sub&gt;G&lt;/sub&gt; is fixed by the gravitational self-energy of the superposition. The framework's contribution here is methodological: the calibrated reference channel and the ''R''&lt;sub&gt;rec&lt;/sub&gt; classifier measure and subtract everything the observer's own finitude contributes, so that a null becomes a genuine bound on objective reduction and a surviving floor is certified as nature's rather than the apparatus's. '''The experiment tests Penrose's proposal, not IOF against quantum mechanics''': if an unrecoverable floor is found, quantum mechanics itself needs repair and Penrose is vindicated; if none is found, his proposal is constrained — and IOF remains exactly what it was, a way of understanding why quantum mechanics works. Neither outcome discriminates IOF from quantum mechanics.

This discipline has a sharp boundary, worth stating: calibration can move only the probability of a ''correct verdict given the data''; it cannot move the probability that objective reduction is true. The instrument decides; it does not vote.

The architecture is also not specific to Penrose. The same calibrate–subtract–classify procedure reads against the whole dynamical-collapse family — spontaneous-localisation (GRW/CSL) models and Diósi–Penrose gravitational collapse alike — distinguished by the variable the surviving floor scales with (mass and geometry for OR, nucleon-number amplification for GRW/CSL). Penrose is the flagship target because its schedule lands in an experimentally accessible mesoscopic window and carries a live debate, not because the method is bespoke to it. The [https://www.qgemproject.com/ QGEM] pathfinder is one candidate testbed; superconducting-qubit readout chains and precision-interferometer phase-locking loops are others.

'''The Fisher-homogeneity module.''' A separate module tests the Born-derivation bridge by measuring whether the empirical Fisher information ''I''(θ) is approximately constant across the calibrated basis range, as the scalar-threshold-homogeneity premise requires. Because a flat ''I''(θ) is ''also'' what standard quantum mechanics predicts for an ideal binary readout, a homogeneous result confirms a shared prediction and lends no positive weight to the bridge; the module is a falsification-only check on a foundations premise, logically independent of the κ-benchmark.

== Relation to quantum foundations ==

* '''The measurement problem'''. IOF introduces no world-side collapse. The host state continues according to the host dynamics, while &quot;collapse&quot; names only the bounded observer's update from unresolved alternatives to a definite record. In Everett all decohered outcomes occur and uncertainty is self-locating; in a scoped single-history host one outcome occurs without an IOF-added stochastic selector. In both cases the observer calls the answer random because the dependencies that determine its record are outside its finite access. Developed at length in ''[https://ignorantobserver.xyz/documents/Where_Did_the_Measurement_Basis_Come_From.pdf Where Did the Measurement Basis Come From?]''
* '''Indexed objectivity'''. The definiteness an observer meets is objective ''indexed to its configuration'' — irreducible at that access, found the same way by every inspector there. Penrose's proposal is precisely that the index can be dropped: that definiteness is absolute, gravitationally enforced, with no log anywhere able to restore the superposition. ''R''&lt;sub&gt;rec&lt;/sub&gt; is that question made operational — ''does the index drop?''
* '''ψ-ontic, collapse-epistemic'''. Within the empirical model the wavefunction is ontic and never collapses, so no-go results in the style of Pusey–Barrett–Rudolph — which constrain ψ-''epistemic'' models — do not bear against the framework; they support the wavefunction realism IOF requires. What is epistemic in IOF is ''collapse'': the record-relative update of a finite observer.
* '''Relational Quantum Mechanics''' (Rovelli) takes outcomes to be relative to an observer–system; the framework offers one candidate physical mechanism — finite ''C''&lt;sub&gt;eff&lt;/sub&gt; against the task-relevant source rate ''h''&lt;sub&gt;θ&lt;/sub&gt; — for what makes one observer's frame physically inequivalent to another's.
* '''Decoherence theory''' is not opposed. The framework brought one further thing inside the physics that decoherence leaves outside: the causal history of the measurement ''setting''. In the capacity-wins regime standard decoherence theory is recovered.
* '''Measurement independence'''. Extended to Bell-type set-ups, IOF does not assume measurement independence: the setting and the system share a common past, so they need not be statistically independent. This places the framework in the superdeterministic family in the technical sense only — non-conspiratorial, with no fine-tuned ledger and no signalling, in the spirit of Palmer (2024). The shared ancestry is real but structurally inaccessible to the embedded observer; the framework names this ''epistemically bounded ancestral correlation''. IOF does not derive the Bell correlations from this alone — the Born weights and joint correlations are supplied by the hosted no-collapse embedding and recovered in the capacity-wins limit. A full consistency treatment, including a no-signalling lemma, remains an [[#Open review targets|open review target]].
* '''Information geometry'''. The conditional Born reconstruction runs from finite-record constraints through a Fisher capacity bridge, Cencov's uniqueness theorem, and square-root record coordinates to ''p''(θ) = cos²(θ/2), with hierarchical binary discrimination extending the weights to one calibrated finite-outcome context. A companion no-go theorem shows this route does ''not'' generate quantum phase, interference between non-commuting contexts, or cross-context composition. Those structures remain host-side, and their unique gluing to the record weights remains open.
* '''Penrose Objective Reduction''' is treated as the live ''discrimination target'' of the experiment, not as a rival to be ruled out by the framework and not as a co-contributing IOF mechanism. The earlier &quot;additive combined-rate&quot; reading, and a speculative ''Bridge Ansatz'' identifying ''E''&lt;sub&gt;G&lt;/sub&gt; with κ, have both been retired: the ansatz met its own failure criterion and survives only as explicitly speculative cosmogony in ''The Creation of Duality''. What remains is the clean division of variables — mass and geometry set ''τ''&lt;sub&gt;OR&lt;/sub&gt;; capacity and instability set the benchmark — and the recoverability classifier that keeps them apart.

== The measurement problem: where the Heisenberg cut sits ==

The framework gives an operational reading of the Heisenberg cut — the boundary between the quantum description used for the system and the classical description used for the apparatus and record. Standard interpretations place it variously: von Neumann showed it can be slid without changing predictions and treated its location as conventional; decoherence ties it to the rate of environmental coupling; objective-collapse proposals fix it universally at a mass scale.

IOF places the operational cut where the observer-apparatus's ''useful'' basis-tracking rate runs out relative to the task-relevant source dynamics — at ''h''&lt;sub&gt;θ&lt;/sub&gt; = ''C''&lt;sub&gt;eff&lt;/sub&gt; ln 2. This production rate is source-side; it is not the entropy of the observer. In the BLQC one-effective-mode source, ''h''&lt;sub&gt;θ&lt;/sub&gt; = ''h''&lt;sub&gt;KS&lt;/sub&gt;, so the laboratory quantity is how that source production appears in the designated tracking task. The resulting κ&lt;sub&gt;θ&lt;/sub&gt; quantifies the operational basis-tracking component of self-ignorance, not the root non-dual limitation itself. This is not an objective collapse boundary; it is a design-dependent threshold the experimenter can move.

That the cut ''moves'' is what the benchmark measures — improving the controller raises ''C''&lt;sub&gt;eff&lt;/sub&gt; and shifts the cut toward more chaotic basis-producing dynamics. This motion is expected control physics, not a departure from quantum mechanics: it is the operational signature of finite self-tracking, calibrated, and it is what the κ-benchmark reads off. The measurement problem took its sharpest form because the cut was treated as floating; the framework's narrower, testable claim is that for a given finite apparatus the cut is not floating but located, by the basis-tracking budget that apparatus devotes to its reference.

== Philosophical interpretation ==

''This section describes interpretive extensions beyond the empirical core. Nothing in it is load-bearing for the operational benchmark or the Penrose test. Everett is the preferred no-collapse host developed in the corpus, while pilot-wave and single-history hosts remain scoped alternatives. The operational machinery and its exposure to experiment do not depend on making Everett exclusive.''

The cleanest entry point to the interpretive position is ''[https://ignorantobserver.xyz/documents/Where_Did_the_Measurement_Basis_Come_From.pdf Where Did the Measurement Basis Come From?]'' (Dekker, 2026). It states the central move — the measurement basis as a physical variable with causal ancestry inside the same history as the system — addresses the standard objections, and names the position ''epistemically bounded ancestral correlation''.

A second interpretive piece, ''[https://ignorantobserver.xyz/documents/Response_to_Rovelli_on_the_Hard_Problem.pdf The Hard Problem Dissolved — But Into What?]'' (Dekker, 2026), engages Carlo Rovelli's Noema essay, marks the ground it shares with the framework, and identifies where the framework presses beyond Rovelli's deflationary physicalism toward a non-dual reading.

The interpretive layer is developed in dialogue with Rovelli's relational quantum mechanics and the Advaita Vedānta tradition (Śaṅkara, Ramaṇa Maharṣi). The production rate in κ is the source-side rate relevant to the designated tracking task; it is not the entropy of the observer. The corresponding operational deficit quantifies one basis-tracking component of self-ignorance. The non-dual claim is deeper and is not numerically identified with κ: from the inside, a finite observer's own limitation makes a world of apparently distinct observers and records appear. The framework presents this as structural interpretation, not as evidence for Advaita or as a claim an interferometry experiment could confirm.

A separate IOF-internal derivation, ''[https://ignorantobserver.xyz/documents/The_Born_Rule_from_Finite_Observation.pdf The Born Rule from Finite Observation]'', obtains ''p''(θ) = cos²(θ/2) from finite-record geometry, with its scope fixed by the no-go companion ''[https://ignorantobserver.xyz/documents/Why_Fisher_Geometry_Gives_Binary_Born_but_Not_Quantum_Phase.pdf Why Fisher Geometry Gives Binary Born but Not Quantum Phase]''. Its metaphysical companion, ''[https://ignorantobserver.xyz/documents/Structural_Resonance.pdf Structural Resonance]'', documents how a structural reading of the ''Kaṭha Upaniṣad'' served as a disciplined search heuristic for the derivation, without claiming that Vedānta proves the Born rule.

A further speculative extension, ''The Creation of Duality'', asks whether space, time, objecthood, and gravity-like structure can themselves be read as features of a consistent finite-observer world-model. The document is under revision and its PDF is temporarily withdrawn.

Readers who prefer to ignore the interpretive readings can evaluate the framework's empirical content from the [[#Technical proposal|Technical proposal]] and [[#The operational benchmark and the Penrose test|operational]] sections alone.

== What a clean result would, and would not, establish ==

* '''A clean benchmark''' (κ-scaling, agreement with the trajectory-conditioned phasor null, and recoverable loss with ''R''&lt;sub&gt;rec&lt;/sub&gt; → 1) validates the calibrated reference-channel model in the tested regime. It does '''not''' establish IOF over quantum mechanics, because the benchmark lies within quantum mechanics.
* '''The Penrose discrimination''' settles a question about gravity, not about IOF. An unrecoverable mass-geometry floor would vindicate Penrose and show quantum mechanics incomplete; its absence would constrain objective reduction at the tested scales. IOF supplies the calibrated subtrahend that makes either verdict trustworthy.
* '''The interpretation''' gains nothing a discriminating experiment could give it, and loses nothing a null could take away. It competes — by coherence and economy — with the other no-collapse readings; a Penrose null leaves it standing among them, neither crowned nor refuted.
* '''The avidyā mapping''' gains a concrete physical anchor for σ&lt;sub&gt;θ&lt;/sub&gt;&lt;sup&gt;2&lt;/sup&gt;(''t'') as a limit on self-observation, but the framework's claim there is structural, not metaphysical, and no interferometry result adjudicates the philosophical positions the mapping connects.

== Open review targets ==

These are the points on which the proposal should be attacked. The list is split into ''core'' targets, load-bearing for the operational claim, and ''further technical caveats''.

=== Core review targets ===

# '''Operationalising the recoverability classifier'''. Recoverability is the framework's ''position'', not an objection to it: the expected case is that the engineered loss is reference physics and returns under conditioning on a passive shadow log. The load-bearing question is whether ''R''&lt;sub&gt;rec&lt;/sub&gt; can be made a clean classifier in practice — whether the logging-fidelity budget can be quantified and frozen, and the recovered-versus-residual contrast separated, well enough to certify any surviving floor as not-the-observer's. If it cannot, the Penrose discrimination loses its subtrahend.
# '''Decoherence confound'''. Distinguishing ''V''&lt;sub&gt;IOF&lt;/sub&gt; from ''V''&lt;sub&gt;std&lt;/sub&gt; in practice is the central experimental challenge of the benchmark. A sufficiently flexible Lindblad / phase-noise model may absorb the predicted curve under suitable parameters; the benchmark gains independent force only when κ predicts visibility timing after thermal, readout, latency, pulse, actuator, and offline-recovery controls have been given every chance to win.
# '''Useful-capacity calibration'''. The framework relies on independent calibration of ''C''&lt;sub&gt;eff&lt;/sub&gt; as ''useful'' tracking capacity, not raw input power or the Landauer ceiling. Establishing that calibration empirically — via the Fisher-homogeneity module or an equivalent operational mapping — is the load-bearing engineering claim.
# '''Instability measure'''. The benchmark must independently certify the task-relevant rate ''h''&lt;sub&gt;θ&lt;/sub&gt;. Identifying it with ''h''&lt;sub&gt;KS&lt;/sub&gt; is licensed only in the one-effective-mode source or by an explicit projection result or coordinate-level calibration. The expanding-dynamics gate must also distinguish deterministic expansion from stochastic diffusion before the exponential tracking submodel is read.
# '''Residual distribution and channel dependence'''. Variance does not determine visibility for an arbitrary phase-error distribution; the exact logged-reference factor is the complex circular phasor. The double-exponential form is registered only when the centered Gaussian or wrapped-Gaussian gate passes and only over the pre-wrapping range. If reference error and baseline coherence are correlated, the joint per-shot model replaces a product of averaged visibility factors.

=== Further technical caveats ===

# '''Nonlinear control bridge'''. Applying the one-mode multiplicative data-rate law to a nonlinear reference coordinate remains an empirical bridge whose finite-range scaling and delivery-schedule dependence must be calibrated directly.
# '''Prior-art and reparameterisation risk'''. The framework must show its predicted curve is not ordinary reference noise, phase jitter, or decoherence in new notation — the purpose of the adversarial-mimic analysis.
# '''Bell / locality consistency'''. The framework implies a non-conspiratorial violation of statistical measurement-independence (following Palmer 2024). A full consistency proof, including a no-signalling lemma for the hosted no-collapse embedding, has not been published.
# '''Scope of the Born-rule derivation'''. The companion note conditionally obtains the binary weight ''p''(θ) = cos²(θ/2) under two named premises and extends the weights through hierarchical binary discrimination to one calibrated finite-outcome context. Complex Hilbert space, tensor-product composition, unitary dynamics, quantum phase, and cross-context consistency are ''not'' derived; they remain host-side, and their unique gluing to the record weights remains open.
# '''Peer-review status and replication'''. The framework has not undergone peer review and the experiments have not been performed. Its case must be evaluated on the documents and on the conduct of the prospective experiment, not on any external imprimatur.

== Invitation for review ==

This page is offered as a venue for substantive critique. The author is particularly interested in:

* '''From physicists in quantum control or precision interferometry''': can the recoverability classifier be implemented cleanly enough on real hardware to certify a residual floor as not-the-observer's, and what existing apparatus is best positioned to host the calibrated benchmark and the mass-geometry sweep?
* '''From decoherence theorists''': under what conditions does the double-exponential law overlap with compound-channel decoherence models in ways that would make a recoverable κ-channel and an unrecoverable one hard to separate in practice?
* '''From researchers in quantum foundations''': how should a non-conspiratorial, epistemically bounded violation of measurement-independence be evaluated against the superdeterminism / retrocausality / many-worlds landscape, and what would a satisfactory no-signalling consistency proof require?
* '''From researchers in information geometry''': is the Fisher capacity bridge the right identification of useful tracking capacity, is scalar-threshold homogeneity the natural reading of the BLQC threshold in a calibrated basis, and is Cencov-based selection the correct uniqueness route? Critique of the no-go boundary — what genuinely cannot be reached from finite-record geometry — is equally welcome.
* '''From philosophers of mind''': the Advaita / RQM interpretive layer is offered conditionally on the empirical core and as an interpretation among peers. Is the conditional structure presented clearly enough, or does it still amount to overreach?

Comments, references to prior or parallel work, and pointers to confounds or alternative explanations are all welcome. Substantive critique on the [[Talk:The Ignorant Observer Framework|talk page]] will be acknowledged in subsequent revisions.

== Documents ==

The framework's documents are published at [https://ignorantobserver.xyz ignorantobserver.xyz], grouped by role.

'''Foundational and bridges'''

* '''[https://ignorantobserver.xyz/documents/The_Ignorant_Observer.pdf The Ignorant Observer]''' — the foundational paper. The philosophical motivation (avidyā as a physical limit) and the technical groundwork from which the project grew.
* '''[https://ignorantobserver.xyz/documents/Where_Did_the_Measurement_Basis_Come_From.pdf Where Did the Measurement Basis Come From?]''' — the conceptual bridge for physicists. States the claim the framework makes about the measurement basis, addresses the standard objections, and names the position ''epistemically bounded ancestral correlation''.
* '''[https://ignorantobserver.xyz/documents/Bandwidth-Limited_Quantum_Control.pdf Bandwidth-Limited Quantum Control]''' — the operational layer: a finite-rate phase-reference control law and its operational benchmark (calibration arm, capacity and instability sweeps, shadow-log recoverability classifier, registered chaotic-corner module).
* '''[https://ignorantobserver.xyz/documents/A_Capacity-Calibrated_Protocol_for_Testing_Penrose_Objective_Reduction.pdf A Capacity-Calibrated Protocol for Testing Penrose Objective Reduction]''' — the prospective experiment: a mass-geometry sweep for an unrecoverable collapse floor, with the BLQC benchmark as its calibration prerequisite. Tests Penrose, not IOF.

'''Foundational extensions'''

* '''[https://ignorantobserver.xyz/documents/The_Born_Rule_from_Finite_Observation.pdf The Born Rule from Finite Observation]''' — derives the binary Born form ''p''(θ) = cos²(θ/2) from finite-record geometry, conditional on two named, empirically exposed assumptions, and extends the weights to one calibrated finite-outcome context. Does not derive complex Hilbert space, tensor products, unitary dynamics, phase, or cross-context composition.
* '''[https://ignorantobserver.xyz/documents/Why_Fisher_Geometry_Gives_Binary_Born_but_Not_Quantum_Phase.pdf Why Fisher Geometry Gives Binary Born but Not Quantum Phase]''' — the no-go companion marking exactly where the finite-record route stops, so the boundary is a result rather than a gap.
* '''[https://ignorantobserver.xyz/documents/Structural_Resonance.pdf Structural Resonance]''' — a metaphysical companion explaining how a structural reading of the ''Kaṭha Upaniṣad'' served as a search heuristic for the derivation. Does not claim Vedānta proves the Born rule.

'''Supplements'''

* '''Forensic Signatures''' — under reconstruction; the PDF and archival deposit are temporarily withdrawn because the null calibration did not reproduce the complete selection-and-fitting pipeline. Earlier numerical findings are not treated as evidence for BLQC or IOF.
* '''The Creation of Duality''' — speculative extension on appearance, gravity, and information from self-ignorance; under revision, with its PDF temporarily withdrawn.
* '''The Capacity–Backaction Frontier''' — application to cryogenic quantum error correction; under revision, with its PDF temporarily withdrawn.
* '''Biological Observers''' — under experimental reconstruction; the earlier timing chain combined quantities that were not calibrated on the same biological tracking task, so its PDF is temporarily withdrawn.

The foundational paper is archived on the Open Science Framework at [https://doi.org/10.17605/OSF.IO/FCDSN doi.org/10.17605/OSF.IO/FCDSN]; the website lists the separate DOI-linked deposits for the companion papers.

Special emphasis is placed on co-simulation and interoperable modeling using the Functional Mock-up Interface (FMI) standard, enabling the integration of multiple simulation tools and domains. Applications extend from individual buildings to districts and urban energy systems, providing the foundations for advanced research in sustainable buildings, energy transition, and future Digital Twin applications. The course combines theoretical foundations, computational modeling, hands-on simulation, and current research challenges in building performance and sustainable cities.

Yonty Friesem&lt;ref name=Yonty/&gt; discusses media literacy education and the Media Education Lab,&lt;ref name=MEL&gt;&lt;!--Media Education Lab--&gt;{{cite Q|Q140686986}}&lt;/ref&gt; of which they are Executive Director. Friesem is an award-winning educator, scholar and filmmaker and an Associate Professor of Communication at [[w:Columbia College Chicago|Columbia College Chicago]]. The Media Education Lab is an online community working to advance digital and media literacy education through leadership development, scholarship, and community engagement. It was founded in 2003 by by [[w:Renee Hobbs|Renee Hobbs]], then at [[w:Temple University|Temple University]]. It has team members, faculty and graduate students in many different countries. 

Friesem completed a 4-year program in Video and Film Production at the Camera Obscura School of Art in Israel in 2001, a BA in Social Science and Humanities at the [[w:Open University of Israel|Open University of Israel]] in 2007, an MA in Management and Leadership in Education at [[w:Tel Aviv University|Tel Aviv University]] in 2010, and a PhD in Education at  the [[w:University of Rhode Island|University of Rhode Island]] in 2015. (Hobbs was appointed the Founding Director of the Harrington School of Communication and Media at the University of Rhode Island in 2012.) Friesem joined Columbia College Chicago in 2018.

Friesem is interviewed by Spencer Graves.&lt;ref&gt;&lt;!--Spencer Graves--&gt;{{cite Q|Q56452480}}&lt;/ref&gt;

== Highlights == 

:''These excerpts from the interview are rushed, lightly edited for readability, and may not be in final form. The ultimate authority on what was said is the accompanying video.''

When asked for the most important things he would like to communicate to this audience, Friesem replied, &quot;Media literacy is not an intellectual kind of thing of scholars. This is something that everybody needs to think about and address with their own personal family, community, life. ... I think most of the concerns of our digital life right now are about those kind of habits of minds of how to work with technology and us controlling the technology and not the technology controlling us, which is the gist of what it means to be media literate.&quot; 

=== Media and conflict? === 

Graves said, &quot;I claim that primary drivers of every major conflict include differences between the media that the different parties find credible&quot;, and ask for Friesem's thoughts. They replied, {{quote|

That's part of it definitely, and I think there is a lack of empathy.

That's my niche within media literacy.

Much of the work on media literacy since the 60s and 80s has focused on cognitive analysis and rationalizing what's the information that you're gathering. 

My claim is that we need to work on the emotional and social first, because we are where we are right now ... because we're not really empathizing or trying to understand the other person. We're just buried in our own echo chambers and fighting to say, &quot;This is right, and you're wrong.&quot;}}

Graves then asked, &quot;How do you get past that?&quot; Friesem replied, {{quote|

That's a very tough thing to do, because it means that you need to start thinking about other people and how might other people think about this information in a different way. ... 

That's one of the toughest questions in media literacy. By not looking at that, we're not empathizing with others and not looking at the humanity in each other and trying to find the connections instead of looking at the gaps and how the other person is wrong.}}

=== Media outlets want their audience to get angry === 

Graves noted that, &quot;Some of my research says that Fox, especially, but really all major media outlets want their audience to get angry at the evil others&quot;, and requested feedback. Friesem agreed, saying {{quote|

It's always easy on the the left to blame Fox News. I'm not saying that Fox News are innocent of being very partisan, but MSNBC is also partisan. CNN is trying to claim they're not, but they have their different ways. We saw even in the first Trump administration how ''[[w:The New York Times|The New York Times]]'', ''[[w:The Washington Post|The Washington Post]]'' capitalize on having Trump on the head news every day ... . 

The news media are definitely benefiting, money wise, from scandals, from making people outraged and have an emotional response to the titles. Most people are reading the titles and not necessarily the actual article that has more nuance .. .}}

=== 2024 Romanian presidential election ===

Graves noted that one of Friesem's recent papers with Nicola and Christina Nistor and Rares Bueran mentioned the annulment of the 2024 presidential election in Romania&lt;ref&gt;Nistor et al. (2026).&lt;/ref&gt; and asked about that. Friesem replied, &quot;In Romania, ... there were two major candidates, as we see in many places. One candidate was more centrist, and one was far right. And there was a use of TikTok in a manipulative way to persuade people toward the far right candidate who claimed to win the election. But then the Supreme Court of Romania looked at the evidence and saw the manipulation that was done through TikTok ... that was basically illegal from the laws about elections in Romania. ... They overruled those, and there were new election. The far right candidate, who was misusing the social media, got banned ... . This is very unique. ... In other places where far right candidates, who've been using social media, won and are in power right now.&quot; 

Graves asked Friesem to compare that to the United States. They replied, &quot;I think the United States is very unique. ...&lt;ref&gt;Freisem praise Sweden. The [[w:World Press Freedom Index|World Press Freedom Index]] Shows Scandanavia leading the world with the US rated &quot;Problematic&quot;. See also [[#Free speech in the US vs. other countries|Free speech in the US vs. other countries]] in [[#Discussion|Discussion]] below.&lt;/ref&gt; We have the somewhat vague definition of hate speech and also about violence, but that's really vague: Does the free speech incite violence? Can you prove that it incited violence? And if you cannot prove it, it's okay as free speech. That doesn't include hate speech, ... but that's a very legal battle that is fought in higher courts ... .&lt;ref&gt;For more on free speech in the US see the [[Foundation for Individual Rights and Expression|2026-07-02 interview with Robert Corn-Revere]], Chief Counsel at the [[w:Foundation for Individual Rights and Expression|Foundation for Individual Rights and Expression]]. See also [[#Free speech in the US vs. other countries|Free speech in the US vs. other countries]] in [[#Discussion|Discussion]] below.&lt;/ref&gt; At the end of the day, the freedom expression in the U.S. is really open, unlike almost any other country in the world.&quot;

=== Recommendations ===

Graves then asked what Friesem thinks should be done to reduce the threats posed by the media literacy problems that they and others have documented. Friesem replied, {{quote| 

As somebody who's been involved in media literacy for 35 years at least, I'm saying that media literacy is not the silver bullet or the ultimate solution. ... 

It's one of the pillars, but we also need social change, cultural change. We need to really address issues of poverty, of inequality, because education cannot solve something that is social economical. Just to say we're going to teach everybody to be media literate while you don't have food in your fridge is not going to help.&lt;ref&gt;Other experts insist that poverty can only be improved by improving media literacy, as discussed in the preface / landing page of the book-in-progress on [[Media Literacy and You]]; see the section on [[#Media and poverty|Media and poverty]] in the [[#Discussion|Discussion]] below for more on this.&lt;/ref&gt;

The young voters that are my students have a lot of social conscience. As part of what we're experiencing now with the second Trump administration, I believe there will be a big wave from the young generation that will come and address the social issues that we see. ...}}

=== Media Education Lab === 

Graves asked, &quot;What is the Media Education Lab?&quot; Friesem replied, &quot;The Media Education Lab is a community of learners that has been built for over 23 years. It's a group of people devoted to media literacy, creating curriculum, doing professional development and research. ...&quot; 

Graves asked, &quot;With scholars and graduate students all over the world?&quot;

Friesem confirmed, &quot;Yes, it's an international group.&quot;

Graves asked, &quot;What would you say are the most important things the Media Education Lab has done?&quot;

Friesem replied, {{quote|

We just finished a grant for the State Department to help Palestinian educators learn all the new innovative ways that we're using media and AI literacy to teach young Palestinians about how to use social media. We were able through a campaign online to reach more than 2 million people in the West Bank and Gaza to learn about media literacy from an online campaign done by the youth who were taught by the instructors that we were teaching for a year ... .&lt;ref&gt;

We just published a day ago the report about it on our platform, so you can see all the work that we have done and the impact that we did.

&lt;/ref&gt;

Also, we've been developing social media standards for what you need to do in schools to teach about social media. Even students who don't have social media yet, but as a prevention way, we call it pause to map, and map is manage, analyze, and participate. ...}} 

=== The role of music, poetry, fiction, art in media literacy ===

Graves asked Friesem to describe the role of music, poetry, fiction, art, and media literacy. They replied, {{quote|

Media is any mediated communication. It can be art murals, plays by Shakespeare, the Bible. Teaching the Bible and analyzing the Bible is media literacy. 

A lot of people think that the word &quot;media&quot; means digital, but it doesn't have to be. Media literacy includes looking at all the classics and all the art and knowing how to analyze it. 

I just came back from a trip in Spain and Italy and Greece and Norway. It was amazing to see art there. I was with my two kids and seeing how they understand and interpret the art and asking them questions to have their minds starting to think about the analysis and synthesis with other things that they're aware of. And they're using YouTube videos to learn more about the context of those art pieces before they see the art piece and after they see the art piece. ... Although they're young, eight and 10, we have a really intellectual discussion about the art piece, which for me is again a baseline of what does it mean to be media literate.}}

=== Motivation to learn media literacy? ===

Graves asked, &quot;What do you find that best motivates humans to learn more about media literacy?&quot; Friesem replied, {{quote|

Unfortunately, something happens, and then they think, &quot;Okay, I don't like what just happened on social media or in a fight with a relative or an article or something that happened. They have different points of view and different resources to talk about and refer to. Only then are people going to media literacy. And many educators are frustrated with what's happening with attention deficit and concentrating in the classroom, and they're looking for tools. Then they discover, &quot;Media literacy is addressing all of those things, and that's what we need right now with our students, with our kids, with our family.&quot; 

It's very easy to blame everything on kids and saying they don't know, and they need to learn at school. I was part of the people who advanced the mandate to teach media literacy to high school students in Illinois. 

But we can see from research that senior citizens are more susceptible than young people to mis- and disinformation on social media like Facebook. There's no way to force adults to come to a workshop, but you can mandate media literacy as part of the curriculum like math and languages. Part of the real struggle right now as a society is how do we help adults to acquire their own media literacy skills? Public libraries are doing amazing, important work, but there are not enough people who are coming and taking that. Some people do take advantage, which is great, but not enough are doing it.}}

=== Intercultural communicative competence === 

Graves asked about, &quot;intercultural communicative competence.&quot; Friesem replied, {{quote|

That goes back to my initial statement about empathy: &quot;Intercultural&quot; is understanding your identity but also being open to the fact that other people have other beliefs, ... We need to be able to have a dialog with them and not just argue, &quot;I'm right, you're wrong,&quot; because that's not even a debate.&lt;ref&gt;Yeh and Friesem (2024).&lt;/ref&gt; 

I'm not a big fan of debates. I'm a more fan of social deliberations, which I think comes as a dialog and not just as a fight. ... 

Presidential election debates are like a ring with two wrestlers.

I prefer a dialog and discussion that has a lot of content and really going back and forth with questions and mutual respect, not a fight to make the other look stupid ..., which is often what we seen in televised debates.}} 

Graves noted that &quot;intercultural communicative competence&quot; is discussed in his paper with Ellen Yeh on &quot;social justice education as an intercultural experience for foreign students in the US.&quot;&lt;ref&gt;Yeh and Friesem (2023).&lt;/ref&gt; 

Friesem said, 'That was a very special research that we did in Ellen's class. She is teaching public speaking to international students while introducing them to American values in a way that might improve their understanding of the education system of their own country.

But what do we mean by &quot;public speaking in the United States&quot;? Looking at speeches by [[w:Barack Obama|Obama]], [[w:Oprah Winfrey|Oprah Winfrey]], different [[w:TED (conference)|TED talks]] and analyzing them from a media literacy perspective. That's helpful for not just learning media literacy but also understanding the cultural differences, which can be discussed in class. ... If I'm coming from Brazil suddenly I'm learning of something from Zimbabwe and then we can learn something about India, China. This supports a dialog about cultural and intercultural competencies and the differences -- acknowledging differences, accepting them, welcoming them, and knowing how to behave differently when you're in that cultural context. 

=== Virtual reality and media literacy === 

Graves then asked about [[w:Virtual reality|virtual reality]] and media literacy. Friesem repled, {{quote|

Fourteen years ago, I went to the [[w:Museum of the Moving Image|Museum of Motion Pictures]] in [[w:Queens|Queens]]. They had a [[w:Virtual reality|VR]] exhibition. I think the movie ''[[w:Clouds Over Sidra|Clouds Over Sidra]]'' was one of the first documentaries done in VR. I put the helmet on and was really amazed, because I felt like I was in the refugee camp with Sidra, the teenager who was walking us through her day in the life. It was very impactful. As I put down my headset from the VR and came back to the museum space, I thought, &quot;That was cool.&quot; I felt for 10 minutes that I was like a Palestinian refugee in Lebanon. But what happened to Sidra, the girl? 

Several years later the director of the film was claiming that VR is an empathy machine. I thought, &quot;That was not really my experience.&quot; My experience was yes, I was there, because my eyes deceive me. I could move and see 360 of the places. But my empathy towards Sidra was not really addressed.

Then I learned that this movie helped UNICEF get millions of dollars in donations. I realized that it's not an empathy machine, it's a donation machine. ...&lt;ref&gt;Friesem (2021).&lt;/ref&gt;}}

=== Nonviolent Communication === 

Graves asked about [[w:Nonviolent Communication|Nonviolent Communication]]. Friesem replied, {{quote|

This goes back to my comment in the beginning, that any analysis must include social and emotional regulation.

Nonviolence Communication by [[w:Marshall Rosenberg|Marshall Rosenberg]] is giving us the steps to get there. Before we start analyzing or trying to deal with a conflict, we first need to regulate ourselves to feel heard, to make sure that the other person understands our needs, understands our perspective of how we observe things. Then we should make sure that we are requesting something that is doable from the other person. ...

The first thing is to focus on the nonviolent stages of connecting to each other. That's the intercultural competency. That's the empathy. All the things that we talked about is bringing it together before we get into the intellectual deliberation on whatever topic we want to discuss.&lt;ref&gt;Y. Friesem and E. Friesem (2021).&lt;/ref&gt;}}

=== Peer feedback and foster youth === 

Graves asked about the importance of peer feedback and with foster youth. Friesem replied, {{quote|

When I came to the University of Rhode Island, I was introduced to an amazing project called First Star Academies,&lt;ref&gt;&lt;!--First Star Academies--&gt;{{cite Q|Q140841585}}&lt;/ref&gt; which is a non-for-profit in Hollywood that helps foster youth. Statistically being in foster care puts you at the most disadvantage to have a graduate degree, no matter your gender, no matter your race.

The foster care system has its own issues, and each state has their own struggle with it. As a nation we're not doing enough to help foster youth to have a leverage and get into higher education. That program was doing that.

We were teaching media literacy in that program that was helping high school youth in the summer on a university campus. Many at the University of Rhode Island and other campuses are doing that. ... 

But we looked at how feedback was given. We started with what we thought was great [[w:sandwich feedback|sandwich feedback]]. ... You want to get to the meat, which is the criticism, but you try to sugarcoat it with some positive thing in the beginning, your actual criticism, and then another sugar sugar coating of like some positive thing. 

And we thought that would be an amazing way of providing feedback.

But the students from the foster care taught us that they're smart enough to know the sugar coating, and they're only listening to the criticism, and that's really disruptive for them.

In one extreme case, a student knew that it was coming, and he couldn't handle it. He was working on a website and knowing that he's going to hear criticism about his website, he deleted all his work just so that he won't get criticism.

That was a big alarm for us to say, &quot;Okay, that kind of sandwich feedback ... is disruptive and not helpful. We need to find another way.&quot; And that's how we develop the empathic feedback that doesn't have any criticism.

It has wonders from the perspective of the person saying, &quot;I think, I believe. And so, when you hear that, it also helps you kind of putting it in an empathic way of like, &quot;Okay, that's your beliefs. I think in a different way, and I might disagree with you.&quot;

So that was this publication. Since then we've been using it in different ways, like talking about what is the importance of empathy in providing feedback and not just giving what's called &quot;constructive criticism&quot;, which is still criticism and is really not helpful. So that has been really a core research of mine of looking how empathy can be helpful in media literacy as we provide feedback to students and other participants.&lt;ref&gt;Friesem and Greene (2020).&lt;/ref&gt;}}

=== Columbia College Chicago ===

Graves asked, &quot;What's Columbia College Chicago?&quot; Freisem replied, {{quote|

Columbia College Chicago is an art and communication school that is based on hands-on experience. The students who are coming to Columbia want to be professionals in their field. If it's theater, if it's voiceover, if it's animation, if it's journalism, you name it. And so they're taught by people like me who have academic credentials like I have a PhD in education, but I was a filmmaker, I was a journalist, so I'm bringing my experience, professional experience, with the academics, and most of the faculty are still working in the field,

And you come to Columbia to really own your skills as a professional, knowing that from the first semester you're going to have hands-on experience, and you're going to work with professional people.

A lot of our internship are paid, and a lot of them are connected with the media market in Chicago, which is the third largest market after New York and Los Angeles.

The students can go and have experiences in theater, in news, in media, in cinema, all the different types of art and communication that exist ... . 

That's what's so cool about Columbia: Our students are very diverse with a minority-serving institution, and they're coming to be professional. And that's what you get in the class. You're with peer groups who want to be professional in that field that you're interested in.}}

Graves asked, &quot;No relationship with Columbia University?&quot; Friesem replied, &quot;No, there are a lot of Columbia colleges around the country, and that's why the full name is Columbia College Chicago, so you know which one it is that you're talking about.&quot; 

=== In sum ===

When asked for final words, Friesem said, {{quote| 

The most important thing in media literacy that you need to know -- and the cheapest but hardest thing -- is to pause. 

That's the first thing from our program. If you pause for 90 seconds, your dopamine and adrenaline drops, and you can not think from your lizard brain that was activated by the emotions of whatever post you saw. Instead, you can calm down and really think: Does it mean that it's true, what I'm reading? Did it try to activate me in a way?

If all of us would take those 90 seconds to pause, our world would be in a much better place.}}

=== Free speech in the US vs. other countries ===

Friesem said, &quot;I think the United States is very unique&quot; regarding its laws regulating speech. They praise Sweden. 

However, the [[w:World Press Freedom Index|World Press Freedom Index]] shows Scandanavia leading the world, consitent with what Friesem said about Sweden, but the US is rated &quot;Problematic&quot;, which suggests that the US may not be living up to the values that Friesem described as &quot;unique&quot;. 

For more on free speech in the US see the [[Foundation for Individual Rights and Expression|2026-07-02 interview with Robert Corn-Revere]], Chief Counsel at the [[w:Foundation for Individual Rights and Expression|Foundation for Individual Rights and Expression]].

=== Media and poverty === 

Friesem said (above), &quot;that media literacy is not the silver bullet ... [Making everyone] media literate while you don't have like food in your fridge is not going to help.&quot; Research summarized in the preface / landing page of the book-in-progress on ''[[Media Literacy and You]]'' claims the opposite: The industrial revolution and the reduction of poverty from the policies of US President [[w:Franklin D. Roosevelt|Franklin Roosevelt]] dramatically improved the lot of the poor and middle class in the US, enabled by diverse ownership of the major media. Increased concentration of ownership of the major media in the US shifted the [[w:Overton window|terms of acceptable political debate]] in the US to the point that inequality and poverty in the US began increasing again after [[w:Ronald Reagan|Ronald Reagan]] became president. Plots of data supporting these claims are included in the chapters in that book on &quot;[[Media Literacy and You/The impact of the media on political economy since the time of the Pharaohs|The impact of the media on political economy since the time of the Pharaohs]]&quot; and &quot;[[Media Literacy and You/Fox, the Great Depression, the Great Recession, and our future|Fox, the Great Depression, the Great Recession, and our future]]&quot;.

[[w:Abiogenesis|Abiogenesis]]

Big Bang

[[w:The God Delusion]] by [[w:Richard Dawkins]]

[[w:The Story of Everything]] film based on [[w:Stephen_C._Meyer|Stephen C. Meyer]]'s 2021 book ''[[w:Return_of_the_God_Hypothesis|Return of the God Hypothesis]]''.&lt;ref name=&quot;bp&quot; /&gt; Backed by the [[w:Discovery_Institute|Discovery Institute]].  Central thesis is [[w:Intelligent_design|intelligent design]], which the mainstream scientific community classifies as [[pseudoscience]]. The [[w:American_Association_for_the_Advancement_of_Science|American Association for the Advancement of Science]], the [[w:National_Academies_of_Sciences,_Engineering,_and_Medicine|National Academy of Sciences]], and the [[w:National_Science_Teaching_Association|National Science Teaching Association]] have issued statements concluding that intelligent design is not science,&lt;ref name=&quot;aaas&quot; /&gt;&lt;ref name=&quot;nas&quot; /&gt;&lt;ref name=&quot;nsta&quot; /&gt; and in ''[[w:Kitzmiller_v._Dover_Area_School_District|Kitzmiller v. Dover Area School District]]'' (2005) a federal court ruled that intelligent design is a religious rather than scientific proposition.&lt;ref name=&quot;kitzmiller&quot; /&gt;


[[w:Edwin_Hubble|Edwin Hubble]] detects [[w:Redshift|Redshift]] in [[w:Nebula|Nebulae]] indicating [[Galaxies and the Expanding Universe|galaxies]] are moving away.

[[w:Steady-state_model|Steady state model]] of the Universe - universe infintely old.  

[[w:Einstein's_field_equations|Einstein's field equations]] predict [[w:Expansion_of_the_universe|expanding universe]]?

Laimaitre meets Einstein at a conferene in 1927

Einstein acknowledges that his fine-tuning of the cosmological constant was the biggest blunder of his scientific career.


1960's implication of General Relativity

[[w:Black_hole|Black hole physics]] - The [[w:Singularity_theory|singularity]] infinite density and infinitely tight space-time curvature.

[[w:Gravitational_singularity|Gravitational singularity]], in general relativity, a point in which gravity is so intense that spacetime itself becomes ill-defined
[[w:Initial_singularity|Initial singularity]], a hypothesized singularity of infinite density before quantum fluctuations caused the Big Bang and subsequent inflation that created the Universe
[[w:Penrose–Hawking_singularity_theorems|Penrose–Hawking singularity theorems]], in general relativity theory, theorems about how gravitation produces singularities such as in black holes.

Jay Richards

[[w:Fine-tuned_universe|Fine-tuned_universe]]

[[w:Fred_Hoyle|Fred Hoyle]] discovered that our universe is fine-tuned for life.  Tries to explain abundance of [[w:Carbon]] in the universe.  Not the big bang or steady state could form Carbon.. only possible to be synthesized in the bellies of stars.  [[w:Beryllium]] and [[w:Helium-3|w:Helium]] combine to make Carbon?  [[w:William_Fowler_(physicist)|William Fowler]].


[[w:Flagellum|Bacterial flagellum]] [[w:Flagellar_motor_switch_protein|Flagellar motor switch protein]]

[[w:ATP_synthase|ATP synthesase]] [[w:Molecular_machine|molecular machines]]

James Watson &amp; Francis Crick discover [[w:Nucleic_acid_double_helix|double-helix]] structure of [[w:DNA|DNA]] suggested duplication process

Discovers that in accord with an independent symbol convention that gives them ability to transmit information.  Digital bit string.  Carrying information for the construction of proteins.

David Kenyon

Codes within codes within codes.  Can be read backwards.  Overlapping.  Bill Gates - like software, but more complicated than anything we've created.

[[Problem of gratuitous beauty]] in evolutionary biology.  Aristotle: product of some rational structure from the Universe. 

True theories often convey a beauty or structural harmony.</text>
