Gravity Bhechoes Ligocatalog Echo Delay Pos

The echo delay theorem

In the Recognition Science framework, a black hole merger is treated as a sequence of discrete recognition events, each at a numbered rung. The framework's geodesic-completeness theorem derives a bounce radius for each rung, and from that radius it derives an echo delay: the time a gravitational-wave echo would take to return after the main merger signal. The declaration echoDelay_pos is a machine-checked proof that this delay is strictly greater than zero at every rung from the first onward. It also proves that moving from one rung to the next multiplies the delay by the golden ratio, roughly 1.618. The proof is axiom-clean: it relies only on the framework's constants and standard real-number arithmetic, with no additional assumptions.

The delay itself is defined as two times the bounce radius times the natural logarithm of the golden ratio. Because the golden ratio is greater than one, its logarithm is positive, and because the bounce radius is a positive power of the golden ratio, it too is positive. The product of positive quantities is positive, which is the entire content of the proof. The adjacent-rung ratio follows from the same definitions: the bounce radius at the next rung is the previous radius times the golden ratio, so the delay inherits that same multiplicative step.

In the framework's account, this positivity is a structural prediction, not a measurement. The declaration names a catalog of four headline LIGO/Virgo merger events, from the first black hole merger GW150914 to the neutron star black hole merger GW230529, and states that each carries a predicted echo at the bounce delay scaled by its source mass. The theorem does not say that any of these echoes has been observed. It does not say that the delay values match any measured signal. It establishes only that, within the framework, the predicted delay is always a positive, well-defined number, and that the delays form a geometric sequence with ratio the golden ratio.

The framework itself states the falsifier plainly: a null result on a high signal-to-noise catalog event with at least one rung would falsify the bounce mechanism. That is a prediction with a named test, not a claim of detection. The machine-checked library of formal theorems certifies the internal consistency of the derivation, not the existence of echoes in the sky.

What this page does not claim

No observed echo has been detected in any LIGO/Virgo event. The theorem does not state that the predicted delay matches any measured value. The framework does not derive the echo amplitude or waveform, only the delay positivity and ratio.

Verify this page

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:

expected axiom basis: [propext, Classical.choice, Quot.sound] (the Lean kernel's standard three; no RS-specific axioms)

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.
