Question about black hole formation and evaporation
1st question, is it not simply that a star has a maximum size before gravity will overpower the other interactions? There’s star size comparison videos on YouTube, but they don’t mention some theoretical maximum, they just keep zooming out to show the next bigger star. I get that some stars are giving off less repulsive force to counter, so it’s not like all black holes form at the same mass cutoff.
2nd, when a black hole evaporates enough mass from hawking radiation, does it stay super super dense, or do the repulsive forces then spread it back out, like does it rein flat to a star or some other stellar body?
