will cause it to emit radiation and lose mass. That's the process we refer to as Hawking radiation. And as time goes by, the black hole will actually just evaporate. The black hole temperature is predicted to be inversely proportionate to its mass. So if you're looking at that massive astrophysical black hole, which even some of the supermassive ones that most galaxies have in their center, the effects of the minuscule with temperature so low that its radiation is basically undetectable. But for really, really small tiny, tiny black holes, things are really, really different.
