sucked
Fortunately, most things around the supermassive black hole are just going to go around it. They're going to orbit it. They don't actually get sucked in.
confined density hole infinitely mass means region zero
We have this interesting problem with black holes. What is a black hole? It is a region of space where you have mass that's confined to zero volume, which means that the density is infinitely large, which means we have no way of describing, really, what a black hole is!
zero understanding black
Black holes are very exotic objects. Technically, a black hole puts a huge amount of mass inside of zero volume. So our understanding of the center of black holes doesn't make sense, which is a big clue to physicists that we don't have our physics quite right.
ucla world telescopes
The Keck telescope, which is the largest in the world, had opened just before I began my faculty position at UCLA.
infinity physics havens
Any time things go to infinity in physics, we know we haven't gotten it right.
