ppl talk about singularity, infinite density, gravition so strong that even light cannot escape, spacetime twisted so much that some laws of physics don't apply there. to an average person who thinks laws of physics apply everywhere, this is very very confusing. one cannot comprehend black holes so easily. What do scientists mean by nothing can return after event horizon? where does that mass go once its crosses event horizon?, it reaches singularity but what after that? there are too many questions and not many answers. and yet black holes are everywhere, every galaxy probably has supermassive black holes at centre running the whole show. i keep reading black holes gobbles up stars, but where does the mass go once its reaches inside black hole is all a mystery to us till date.
