Abstract

Event horizons of astrophysical black holes and gravitational analogues have been predicted to excite the quantum vacuum and give rise to the emission of quanta, known as Hawking radiation. We experimentally create such a gravitational analogue using ultrashort laser pulse filaments and our measurements demonstrate a spontaneous emission of photons that confirms theoretical predictions.

    • I specifically stated we have not seen it coming off of a black hole, but dismissing this as just a simulation is silly and reductionist. To do the same in a counter-argument, if I can accurately model fluid dynamics, I don't have to go drop a log in my bathtub to observe the…
