A black hole is a region of spacetime exhibiting such strong gravitational effects
that ..... from the ergosphere with more energy than they entered. This energy is
taken from the rotational energy ...
Stellar black holes form when the center of a very massive star collapses in upon
itself. This collapse also causes a supernova, or an exploding star, that blasts ...
In the case of a black hole, it's best to think of gravity as Albert Einstein described
it: a warp in space-time. Einstein's theory of special relativity says that mass ...
A common type of black hole is produced by certain dying stars. A star with a
mass greater than about 20 times the mass of our Sun may produce a black hole

Black holes are the most exotic and awe inspiring objects in the Universe. Take
the mass of an entire star. Compress it down into an object so compact that.
Stellar Black Holes. A star is massive. The gravitational acceleration at the
surface is... um, ... for small mass black holes, rather than sucking all the mass in,
the mass becomes gravitationally binded, causing the mass to orbit the black
Every object in the universe--from a basic star to an exotic black hole--spins, and
the origin of that spin can be traced back to the very beginning of time.
