Black Holes

Billions of miles away, a black hole is out there somewhere. Black Holes are invisible because anything that enters a black hole is trapped...Even light! Around the black hole is a surface that we can't detect, which marks a point where you won't return. This is called an event horizon. A black hole reflects nothing. Nothing can escape from within the event horizon. If you were to stand on a black hole, you would get sucked in at the speed of light!
Black Holes are packed together areas of mass so vast, that the mammoth force of gravity denies everything within a certain area around it from passing. That area is the even horizon. Scientists believe that a black hole is caused when a red super giant star collapses.
Information on black holes is limited because mankind can't see them, but we know about them because of the impact they have on space around them. Below are stimulations of black holes.
