Hello people, I have a question regarding black holes. The way i understand it, black holes form in supernovas, and they occur because the gravitational pull of the stellar remnant is so great that nothing can stop it, and it basically collapses down to a singe point, virtually nothing... Now, my knowledge of Physics is very limited, since i've only just began studying university level physics, but i've learned that points can't have spin right? Because they are points, rotation itself doesn't make sense. But if that's the case, isn't the conservation of angular momentum broken when a black hole forms? Since the remnant that created the black hole was spinning, as it collapsed, no matter how brief and quick that collapse happens, it should spin faster and faster until it becomes a point and then angular velocity becomes...infinite? Or just none? Don't both cases break the conservation of angular momentum? Or does something else happen that somehow obeys the rule? I would appreciate an answer to this question, thanks for any replies!
