i was bored and my mind wandered. a question popped up and it got me interested in what others thought who are more informed than me: since black hole is a theoretical construct (and hence can be geometrically perfect), what happens at the exact center of it. with uniform (assumed) density the geometric center of the black hole should have centripetally directed equal force of gravity perfectly in all directions, hence net zero force. so what happens there within this "singularity"? theoretically, there should be an equilibrium point of all forces near the center, even in a non-uniform black hole. as one radiates out from that equilibrium point there should be a graduation in variation of the force. as a consequence would there be a event horizon near the center of the black hole?
