Black Holes: Horizon Response

After two black holes merge, the remnant settles by emitting gravitational waves. This project asks how such a signal could test a proposed response at the horizon, and what an experiment can actually distinguish.

Research status

A hypothesis, methods and reproducibility release. It establishes neither an HRF detection nor a quantum horizon, area quantization or an exact ln(4) identification.

What the public work reports

An exact-point testing limit

Under the stated total-variation continuity condition, alternatives can approach an exact target so closely that uniform separation vanishes. This does not rule out learning about fixed, separated alternatives.

A repeatable archived calculation

The fixed-conditioning −7M replay contains an 85 × 40 grid. Its released-row network maximum is 200 Hz, 450 s⁻¹; an alternate released row gives 200 Hz, 420 s⁻¹. Several inputs change together, so this does not isolate a causal parameter effect.

Agreement within the computation

The archived centered cache-to-raw maximum discrepancy is below 7.8 × 10⁻⁵ log-likelihood units. This supports the specified computation, not independent astrophysical confirmation.

Assumptions and open questions

Gaussian separation calculations are stipulated design requirements, not measured GW250114 precision. Full nuisance, calibration, global identification and search-null calibration questions remain unresolved. Integrity checks do not run a new raw-strain analysis.
