Hey guys this is my first post so I hope this doesn't come out stupid since I only know slightly more than a layman. Recently I have been trying to wrap my mind around what happens inside an event horizon. Specifally I have been confused with the matter which resided inside the schwarzchild radius before the collapse. I know that matter falling into a black hole accelerates until it hits the event horizon, but matter which was already inside the event horizon may be able to move freely. I know there is no actual evidence about what happens in there, but I want to know if there are credible models or theories which predict what may happen inside the EH concerning the matter which resided and still resides inside the shrwazchild radius?
