If black holes curve space so much that nothing, even light, can escape the event horizon, how do they also emit radiation?

Question

Isn’t light just a form of radiation? How come it can’t escape, but other radiation can?

In: Physics

Answer 1

The radiation isn’t emitted directly from the black hole, but from the matter falling into it, as such it isn’t coming from behind the event horizon and therefore isn’t trapped by it.
