'Project Anchor' — claim that gravity switches off on 12 August 2026

That at 14:33 UTC on 12 August 2026, intersecting gravitational waves will switch off Earth's gravity for seven seconds, per a secret NASA program called 'Project Anchor'.

A viral rumor that Earth's gravity would stop for seven seconds on 12 August 2026. NASA said plainly that it would not, and on the day it did not. Gravity is produced by Earth's mass, which stayed where it was.

Anonymous social-media accounts citing an unpublished 'NASA document' — rumor / popular framing.

Fact-checkers trace the narrative to an Instagram video of 31 December 2025 presenting an alleged 'Project Anchor' document. It moved to TikTok, X, and Threads through early 2026, drawing millions of views and prompting an explicit NASA denial, a BBC Bitesize explainer, and fact-checks in several countries.

WHY IT RESONATEDThe claim arrives with institutional furniture — a codename, an $89 billion budget, a 94.7 percent probability, and a time to the minute — none of which has a document behind it.

12 August 2026 passed with gravity fully operational. No observatory reported an anomaly, no agency revised anything, and the alleged Project Anchor document remains unproduced. The claim's most durable legacy is its structure, which the next rumor of this type will almost certainly reuse.

There was no document, no program, and no mechanism. Gravitational waves are real but are measured at scales smaller than a proton's width; two of them meeting does not cancel a planet. The claim's precision was decoration, not derivation.
