If you've been on this Earth long enough, you probably know, or have heard of, a black hole. These big scary things in space that suck everything into them and everything that goes in never comes out. Although this hypothesis is, in some ways, correct, it is not all that a black hole actually is. This leads you to ask the question: what is a black hole? First, everyone knows that black hole holes form when a star dies and collapses in on itself. If you compress an object into a space small enough to the point where its density and gravitational pull would be so great that even light couldn't pass through it, you would have black. hole (hence the “black”). There are two types of black holes: a Schwarzschild and a Kerr. The difference between a Schwarzschild and a Kerr is that a Schwarzschild black hole does not rotate, a Kerr black hole rotates. four parts of a black hole, the singularity (the core), the event horizon (the opening of the hole), then the ergosphere is the egg-shaped region of distorted space around the horizon events (since gravitational attractions bend space and time, the ergosph...
