The gravity is enormous! The gravity in a black hole is high enough to stop light escaping.

Black holes have an enormous?
Depending on the size of the black hole, they may or may not have:* An enormous mass; * An enormous gravitational pull (depending how close you are, of course); * An enormous density (depending how you define density; if you take the volume of the event horizon, a supermassive black hole actually has less density than water).
What kind of enormous pull does the black hole have?
plain old ordinary gravity, just lots of it
How is the formation of a normal black hole different from the formation of a supper-massive black hole?
It is not yet known for sure how a supermassive black hole acquires the enormous mass it has. It is possible that it starts as a normal black hole, and then gets more mass. It is also possible that from the start, a much larger amount of mass than in a normal black hole collapses.
Why do black holes come in different sizes?
Because of their previous history. The star that converted to a black hole may have had more or less mass for a start. Also, a black hole can increase in mass when matter falls into it, so depending on the amount of matter available for the black hole, the results may vary.However, it is not yet known how the galactic black holes achieved the enormous mass they have.Because of their previous history.

Does matter change into energy when in a black hole?
Nobody knows, but most probably the enormous gravitation of the black hole(which traps light in its core, therefore it is black from outside) breaks down every material to its very elemental pieces
Is a black hole a living organism?
No. Black holes are huge stars that have collapsed so far that their force of gravity is so enormous that even light cannot escaple. (Hence, they are 'dark' )
Are black holes made of dark matter?
No, dark matter is quite a different kind of thing. A dark hole may have absorbed some dark matter, but pressumably that would become indistinguishable from the normal matter, once it gets crushed by the enormous gravity of the black hole.
Why do astronomers hypothesize that a massive black hole lies at the center of M 87?
A very small region at the center of M87 releases an enormous amount of energy.
A collapsed star from which light cannot escape?
The collapses star gets squeezed by collapses gas and turns into a black hole.
Are all black holes made of dark matter?
No, dark matter is quite a different kind of thing. A dark hole may have absorbed some dark matter, but pressumably that would become indistinguishable from the normal matter, once it gets crushed by the enormous gravity of the 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.

Is the dust and gas found between stars called quasars?
No. The clouds of gas and dust are called nebulae. A quasar is a disk of superheated matter falling into an enormous black hole.
