What is A black hole?

Question

What does a Black Hole supposed to do

Answer 1

a black hole is the true definition of nothing....

there is nothing in it.

no molecules

no air

no life.

it is a vortex, which due to a gradient, sucks up all around it.

Answer 2

A black hole is also referred to as a Singularity.

It has been generally accepted that Mass determines gravity. The larger the Mass, the more gravity the thing will have.

A black hole is aledgedly a sun that expanded into a super-giant, and became so massive that it collapsed back into itself. It's gravity is so powerful that not even photons (light) can escape, that's why it is called 'black', and the gravity just sucks in every thing around the darkened singularity so that all sorts of stuff gets pulled in but doesn't seem to come out anywhere, which is why it is called a 'hole'.

So a 'black hole' is an object so massive that it's gravity caused it to collapse into itself and its gravity drags all the space stuff into it.

All this activity causes a lot of microwave and electromagnetic activity in and around the black hole. It is a very busy (and dangerous) spot in the universe.

Astronmers believe they have located dozens of black holes, and that there is a giant black hole in the center of our own galaxy.

Now since zillions of tons of stuff gets sucked into a black hole per second, causing all sorts of radioactive and microwave activity to occur, where does all that stuff go?

Astronomers have observed another phenomenon in deep space far away from black holes called Quasars.

This is just speculation, but there seems to be a lot of energy emanating from a Quasar. A lot more energy than should come from such a small object. Some astronomers asked if all that energy could mean that a Quasar is the exhaust from a black hole? But that is still theory.

Answer 3

Supposed to do? We have no idea.

What scientists theorize is that black holes are created by the dead and subsequent collapse of some dwarf or neutron stars with certain characteristics. Black holes are so massive, yet so tiny, that they have an extremely high density and therefore extremely high gravity. This gravity pulls in everything around the black hole into it, destined to become part of the black hole's growth. The gravity of the black hole is so extreme that not even light can escape its gravity, which is why they appear black.
In some occasions a black hole will consume all of the matter that is close enough to it to be influenced by its gravity. These black holes continue in space but no longer grow and are no longer visible to us, until they find themselves near enough to something to start consuming again.

Answer 4

When a star much larger than the sun runs out of fuel it collapses in on itself. There is so much mass that it collapses into a point smaller than an atom. The gravity is so high that even light cannot escape and anything that comes near it falls into its gravity. The last anybody sees of the matter that has been caught by a black hole is as it is falling into the event horizon and it gets heated up by all the friction.

Answer 5

A black hole is the results of a collapse sun . As it collapse the gravity acceleration makes the particles fall faster and faster until they travel at the speed of light . And when that happens the material has a mass of infinity. The gravity is so great it may be 100 light years across . That will hold all the solar system around it.

Answer 6

A Black hole is a hole in the space that sucks everything that comes close to it.

Answer 7

A black hole is a black colored hole that has a lot of gravity at the end that it will crush anything inside.

Answer 8

A black hole is a star that has reached its final final expantion to a "red giant" it collasape's in on itself I'ts gravity sucks everthing , including light toward it. thus the name "black hole"

Answer 9

A black hole sucks up galaxy's.

Answer 10

It sucks up whatever goes near it and it kills
