Hello guys.
From my understanding of the Hawking radiation, it is a consequence of QFT in curved space time. The fact that a uniformly accelerated observer sees the Unruh radiation means that by the equivalence principle, a stationary observer at a distance from a black hole will see Hawking radiation. Is this correct?
If my understanding is correct, what would a freely falling observer see? Would an observer in a free fall orbit around a black hole no longer detect a Hawking radiation, just as a freely floating observer in free space detects no Unruh radiation? How can this be reconciled with the fact that the black hole will evaporate in finite time? Or is my understanding incorrect?
Thanks.
