Question

Does a black hole cool off and obey laws of thermal equilibium?

Answer 1

Nothing gets out of a black hole, I understand, except Hawking radiation.

Now every object in the universe is trying to get to thermal equilibrium with its environment.

All these answers did not talk about whether the black hole can/does exchange heat with the environment (vacuum).

Since nothing escapes a black hole, is a black hole an exception of the law of thermal equilibrium

Answer 2

All these answers did not talk about whether the black hole can/does exchange heat with the environment (vacuum).
