right, so black holes have a thing called an event horizon, which is a sort of radius around the black hole. after you pass the event horizon, space and time flip. i'm not entirely able to verbalize why, but this means that you can't escape being sucked into the singularity, which is the point when the force of gravity becomes infinite. insofar as i understand it, basically the fact that we progress unilaterally in time becomes a progression unilaterially in space, and instead of moving physically towards the black hole, it just becomes your future.

with spinning black holes, there are two event horizons - the first flips spacetime, and the second sets it back right. at which point, you can avoid the singularity. which, with a spinning black hole, actually isn't that hard, since unless you approach it equitorially, its gravitational force is repulsive.

not to mention the two photon spheres, the ergosphere, the conversion of potential gravitational energy to kinetic energy, the eliptical singularity, and anything else i haven't discovered yet.

and i only get five minutes of presentation time.
excuse me, i have to go practice my speedtalking now.
