i understand that a black hole occurs because the atoms are not strong enough to hold back gravity after a certain point. is the matter continually collapsing on itself or does it stop after the atoms have been crushed? like is it a runaway effect?
my next question is why does a large mass in a small area create more gravity? thinking about the rubber sheet analogy... if you have 2 balls of the same mass but different densities (therefore different volumes)... will the denser ball really create a larger indent in the rubber sheet? i don't understand why the required gravity only occurs when an amount of mass is compressed in a small enough space.
my last question... there are two different things that I've found to define black holes. 1. light doesn't escape and 2. matter has collapsed on itself. my question is... do these occur at precicely the same moment or do they occur at different moments? are we able to have a gravity so powerful that light doesn't escape, yet matter isn't collapsed? are we able to have collapsed matter with light escaping from it?
thank u so much
