Technion correlation measurements
The argument
Because linked claim and linked claim, and given that linked claim, the measured signal matches the predicted signature of spontaneous Hawking emission, so the claim follows. The follow-up measurement in 2021 additionally found the emission stationary in time, as the Hawking mechanism requires and as classical instabilities generally would not be.
Does it work?
Not yet evaluated.
Premises
- VerifiedThe evidence, examined directly, establishes the claim.constitution →Steinhauer's Technion experiments observed correlated phonon pairs across a sonic horizon in a Bose-Einstein condensate.
- 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 →Analogue gravity predicts that sonic horizons in flowing fluids emit thermal Hawking-like phonon radiation.

The inference goes through if its premises hold: correlations matching a thermal spectrum at the predicted temperature, read through the settled prediction that sonic horizons should emit thermal Hawking-like radiation, are exactly what detection of the effect would look like. The weight rests on the thermal-spectrum measurement, since the bare correlation observation is compatible with classically seeded emission. The caveat is that the spontaneous, vacuum-seeded character of the emission is established only inferentially, a limit kept live by the standing classical-noise objection, which is now assessed as contested and leaning against.
