Verification Ehtm87 Strong Field Likelihood

EHT M87* Likelihood Certificate

The Event Horizon Telescope's 2019 image of the supermassive black hole at the center of galaxy M87* shows a bright ring of emission around a dark shadow. The ring's diameter is 42 microarcseconds, with an uncertainty of 3 microarcseconds. Two additional measurements describe the image's shape: the ring's circularity deviation is at most 10 percent, and its shadow size is consistent with the Kerr solution of general relativity at roughly the 17 percent level.

Recognition Science (RS) is a framework that derives physical structure from a single starting point: reality keeps a ledger, a discrete record of recognition events, and the cost of recognition is forced, not chosen. From this starting point, the framework derives a chain of results including a prediction for a tiny positive fractional deviation from pure general relativity and Kerr black holes, represented structurally by the quantity φ⁻⁴⁴, where φ is the golden ratio. This target scale is the framework's predicted size of any deviation from standard black-hole physics.

The verification module for EHT M87* strong-field likelihood establishes two honest facts. First, the RS structural target is within the current EHT shadow-size and circularity sensitivity scales. The residual between the current Kerr-consistent central fractional deviation (0) and the RS target is less than both the 17 percent shadow sensitivity and the 10 percent circularity sensitivity. Second, EHT is not currently sensitive to the RS target scale: φ⁻⁴⁴ is far below both 17 percent and 10 percent. The module proves these facts as formal theorems in a machine-checked library of formal theorems, with zero unproved assumptions and zero new framework-specific axioms.

The module assembles these facts into a certificate structure, named EHTM87StrongFieldLikelihoodCert, that bundles all the positivity, compatibility, and non-sensitivity statements into a single object. A theorem proves this certificate is inhabited, meaning all the required conditions hold. The one-statement theorem packages the entire result: the shadow residual is below the shadow sensitivity, the circularity residual is below the circularity sensitivity, the RS target scale is below both sensitivities, the current sensitivity flag is false, and the certificate exists.

This is a consistency and non-sensitivity test, not empirical confirmation. The module does not claim the RS target is real or observed; it claims the framework's prediction is not ruled out by current data, and that current data cannot yet see the predicted effect. The practical consequence is a clear experimental roadmap: to test the RS prediction, future telescopes must improve sensitivity by roughly seventeen orders of magnitude, from the 10 percent level down to the φ⁻⁴⁴ scale. The certificate makes the gap explicit and formal.

What this page does not claim

This module does not claim empirical confirmation of the RS target. This module does not claim EHT can detect the RS prediction. This module does not derive the value φ⁻⁴⁴; it takes it from the strong-field attachment.

Every tagged claim above names its theorem. To check one yourself rather than trust this page, elaborate the source module with Lean 4 and audit its axiom basis:

A page whose claims cannot be reproduced this way does not ship. In production, every anchor links to the exact declaration in the public source release, and this block carries the build receipt for the page itself.
