The title text in Wiki Answers sums it up quite well: "Black holes are regions in space created by the death of stars. Their gravitational field is so strong that even light cannot escape from it."The strong gravitational field is caused by stars collapsing, into a very small space.

How can you tell if there is a black hole?
Astronomers look for black holes by searching for their effects (the hole itself by definition can't be seen). Some of the possible effects are gravitational lensing and electromagnetic radiation from the hole's accretion disk.
What happens if you explode an Atomic Bomb inside a Black Hole?
The force of the impact will still be absorbed by the black hole. By definition, a black hole is a very dense mass where no form of radiation can escape - not even light. Since no explosion is faster than light, a black hole would absorb the blast, the impact, and all forms of light and radiation that would be emitted from the bomb. If you were to watch a black hole, you would see no changes from it.
Could the universe have started as a black hole that exploded?
No, because (by definition), a black hole is so dense, causing a gravitational so strong, that no matter can escape from it. In other words, no matter can possibly explode out of a black hole. No matter how strong is the internal pressure of the matter within the black hole, the gravitational pull is stronger. Asking, "Can a black hole explode?" is like asking, "Can I blow up Fort Knox with a one centimer, gunpowder fire-cracker?"
A collapsed star from which light cannot escape?
The collapses star gets squeezed by collapses gas and turns into a black hole.
What is the difference between a Scchwarzschild and a Kerr black hole?
A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole. Since the latter is more complicated to describe, it was developed much later.A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole.

If the whole mass of the universe was once contained in a baseball sized volume why was this not a black hole by definition so is our universe a failed black hole and each black hole a failed universe?
Partially because when the universe was the size of a baseball the four principle forces were not yet separate, but one force. So there was no gravity to create a black hole, there was no strong force, weak force, or the force of electromagnetism.
What is the basic definition of a black hole?
A black hole is a region of space in which gravitation is so strong that not even light can escape found at the centers of galaxies and also as the final stage after the death of very massive stars.
What does the black hole do to the star?
A black hole originated as a star, that is, the star converted to a black hole.
What does a black hole do with what it suck in?
The material sucked in to a black hole becomes part of the black hole - that is, a black hole crushes matter to an nearly no size, at all.
Where will you go in a black hole it?
If you fall into a black hole, you'll go into the black hole and nowhere else.
The definition of object with strong gravitational pull that nothing not even light can escape from it best fits which science term?
Black Hole
What is the environment in a black hole?
probs black hole
