: : What are blackholes (its for a science project)?

: Here's what I know. Stars are in balance. All their mass : generates gravity which tries to crush the star to a smaller : size. The star burns fuel (hydrogen in the beginning) which : generates equal pressure that counteracts the gravity. The : star goes on like this for a while. Without going into great : detail, stars eventually run out of fuel. Gravity, no longer : countered by the burning of fuel, pulls the matter of the star : to a much smaller size. Much denser, this smaller star has a : high density. The results in a very concentrated gravity "well."

: Now the black hole part.

: Very large stars have so much matter that when they crush down to : this small size thay have an extreme amount of gravity. Light : is affected by gravity; Starlight bends around the sun for example. : If gravity is strong enough, any light generated by the old star : bends around and comes back to the star; Thus light never leaves.

: This is what a black hole is as I know it. I have skipped many : things about stellar evolution.

: Let's here from the astronomers out there.

: I will try to find some web sites and list them : on Astronomy Net to help you find information.

: John what would happen if two black holes collided?
