Is Hawking radiation really the same as Unruh radiation?

WebThe Ffowcs Williams–Hawkings (FW–H) equation has been extensively used to model sound generation by moving surfaces including the noise of aircraft propellers, helicopters rotors and turbomachinery [33]. The FW–H equation allows for surfaces in arbitrary motion in a medium at rest or a uniform flow. The FW–H equation has been extended ... WebHawking radiation, Radiation theoretically emitted from just outside the event horizon of a black hole. Stephen W. Hawking proposed in 1974 that subatomic particle pairs (photons, neutrinos, and some massive particles) arising naturally near the event horizon may result in one particle’s escaping the vicinity of the black hole while the other particle, of negative … dicks sporting goods sneaker release calendar
