Question

what is black hole and what happens in black hole.

Answer 1

Scientists think the smallest black holes formed when the universe began. Stellar black holes are made when the center of a very big star falls in upon itself, or collapses. When thishappens, it causes a supernova. A supernova is an exploding star that blasts part of the star into space.

Answer 2

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.The place where light cannot even pass is called the event horizon.Scientist say that near the black hole time stars passing very fast.The black hole core or you can say inside the black hole is singularity ,a point or region in spacetime in which gravitational forces cause matter to have an infinite density.
