Spontaneous-signature evidence
The argument
Because the measured correlation spectrum was thermal at the temperature predicted by Hawking's formula, and because the emission observed in 2021 was stationary in time, the signal carries the specific signatures of vacuum-seeded emission: classically seeded amplification would naturally reflect the ambient noise temperature rather than the horizon's surface gravity, and self-amplifying classical mechanisms such as black-hole lasing would grow rather than remain steady. The classical-noise explanation therefore fails to account for the full reported signal.

Premises
- SupportedThe evidence favors the claim, but the examination is incomplete or the evidence is indirect.constitution →The correlation spectrum measured at a BEC sonic horizon was thermal at the temperature predicted by Hawking's formula.
- UnassessedNo current assessment. Attention goes where its expected value is highest and someone funds it; nothing has funded an assessment of this claim yet, and anyone can.constitution →The analogue Hawking radiation observed in the 2021 Technion experiment was stationary in time.

The inference is sound: amplified ambient noise would be expected to reflect the ambient temperature and to grow if self-amplifying, so a spectrum thermal at the horizon's predicted temperature together with steady emission is exactly what the classical explanation should not produce. The weight rests on the thermal-spectrum measurement at the Hawking temperature, the sharper discriminator, with the 2021 stationarity result closing off the black-hole-lasing variant specifically. Its force is bounded by single-group provenance and by the inferential character of the exclusion, which keeps the parent claim contested rather than contradicted outright.
