A black hole is a super-dense object in space, usually a star, which has become so massive it has collapsed in upon itself. The mass of such an object is so great that the gravitational field it creates pulls in everything nearby. As an object draws closer to a black hole, the gravity exerted upon it becomes more powerful, requiring more and more energy to counter the curvature of space. The speed it would take to overcome this curvature and pull away from the black hole is known as escape velocity.
When an object draws close enough that its escape velocity exceeds the speed of light, the upper limit of how fast any object in the universe can travel, that object is trapped and will inexorably move in towards the center of the black hole, known as the singularity. The point at which the escape velocity exceeds the speed of light is called the event horizon. Nothing which has passed that point will ever return to normal space.
As indicated above, the gravity of the singularity is so strong that nothing, even light itself, moves fast enough to escape the pull. The inability of light to get away from the object is what gives the black hole its name.

Could live on the black hole?
the strong force of the black hole means that you cannot live in it
What is the most distant black hole in center of a quasar cal led as?
Quasars have a large black hole, called a "supermassive black hole". The term "supermassive black hole" simply means that it has millions or even billions of solar masses.
What does it mean when light could not escape?
In the case of a black hole, the gravitational pull of the black hole is greater than the speed of light. Which means that the light is not fast enough to escape the gravitational pull of the black hole.
What would happen if you jumped into a Kerr black hole?
If you jumped into an "ordinary" Schwarzschild black hole, you would be crushed into a long line of particles, which means death by a black hole. If you jumped into a Kerr black hole, the same process may occur, but the only thing different is that a Kerr black hole spins, and a Schwarzschild black hole does not. That answer needs a bit more detail. Please use the "related link" below.
Why is the term black hole appropriate?
The term 'black hole' is particularly appropriate in its application to the astrophysical phenomenon of the same name due to the property of the escape velocity exceeding the speed of light. This means that no light or matter escapes a black hole.
Is it possible that there is a tiny black hole in the center of Bermuda triangle?
It is scientifically impossible to have a black hole in any parts of the Earth. If there was one, means that the tiny black hole would suck up everything, even time and even the moon.
A collapsed star from which light cannot escape?
The collapses star gets squeezed by collapses gas and turns into a black hole.
Where does a dark hole in outer space lead to?
A black hole is the location of a singularity, it doesn't lead to anywhere. This means that if you fall into a black hole (assuming that you can stay alive) you'll just be stuck inside that hole forever--never able to get out.
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.

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 is the name of black hole growth?
As far as I know, there is no specific word for the growth of a black hole. I am assuming you're asking about the addition of mass rather than the birth of a black hole. The word used would be "accretion." Accreting means growing.via the addition of mass.
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.
