Galaxies form and evolve around supermassive black holes, but the black holes do not create the galaxy by exploding. Rather, the black hole and the galaxy influence and grow with each other over billions of years.

The entropy of a black hole increases as it absorbs more mass and energy. In fact, black holes have an extremely high entropy and are considered to be the ultimate sources of entropy in the universe.

The only mechanism for a black hole to release energy is through a process called Hawking radiation, but this is a very slow process. For a black hole to evaporate entirely, it would take an unimaginable amount of time, far longer than the current age of the universe.
