Question:
What do black holes and white holes do?

Replies:
A black hole is a collapsed star or body that has become so dense that it becomes smaller than nature wuld have expected for that mass. This means that the gravity outside of the body will be very different at a particular distance call ed the event horizon. The black hole is believed to be the end point of a very massive star when it is finished burning it nuclear fuel. White holes are theoretical ideas that would give out mass instead of pulling mass in as black holes must do. There is evidence for black holes, but none for white holes.
