In his theory, Stephen Hawking suggests that a black hole will give off thermal radiation. Radiation is light, so how can light escape the gravity of a black hole, especially originating from one? The only way I could see this was that if radiation were traveling beyond the speed of light, but that's not possible, right?

it doesn't come from the black hole …

it comes from the intense gravitational field just outside the event horizon :smile:
