A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.

BLACK HOLE
••••••••••••••••••
black hole is a location in space such a strong gravitational field that the escape velocity exceeds the speed of light.
this mean is that you require a velocity greater than the speed of light to escape the black hole.
In general relativity, mass warps spacetime depending on the mass-density, and so when you pack a lot of mass in a very small area, spacetime curves so severely that it traps even light. Since a black hole does not reflect—apart, potentially, from the nearly undetectable Hawking radiation—it is thus completely black.
