The universe is expanding as described by Hubble's law, which means that at a certain distance from an observer, expansion exceeds the speed of light, so all waves become infinitely red-shifted. In other words, if an goes beyond this point, no information about it can ever come back to the observer.
My question is this: Does that mean that every observer has a sort of event horizon at that distance? If so, shouldn't that even horizon emit Hawking radiation?
