After that big discussion on gravity, you are now ready to hear about black holes. As I said before, mass causes a "dent" in the fabric of space-time. This can be illustrated by this picture:


As you can see, there is no bottom. As you can probably imagine, this creates a problem in physics. The straightest path through space in a black hole goes into nowhere. With normal object, the path either leads to a collision of the two objects, or an orbiting path. In a black hole, though, most paths lead into nothing. There is the small chance you can orbit, but where does everything else go? Please ask questions, because I have much more info that I can't quite figure out how to integrate. I will be posting more on this; I'm not done yet! ;-) There will be at least a part three!
