      According to general relativity, gravity is caused by curvature of spacetime. Near a very compact massive object, gravity is so strong that time points inwards. Therefore nothing can come out, even light, because it would mean going backwards in time. Because no light can come out, the object appears black, and we call it is black hole. Black holes are created when a large star runs out of fuel and collapses under its own gravitational field.

      If you fall into a large black hole, you won’t actually notice anything happening when you cross the surface (which is called the event horizon), but after that you can no longer stop or turn around. You will keep falling is, and very soon you will hit a singularity at the centre of the black hole and be destroyed. This is at least what the theory says. Of course we cannot know for sure because no information can come out of the black hole.
