What is a black hole, and how is it formed?
Black holes are formed when big stars fall upon themselves or explode. This is called a supernova. Stars are made up of a lot of matter, so when there’s a supernova the matter from the dead star has no where to go so it comes together to form a black hole. There’s so much matter in a small space that it all packs together and creates a super strong gravitational pull, so that nothing, not even light can escape.
^This picture is showing the process of a supernova, which is a star falling upon itself or exploding. The matter from the star forms a black hole in its place.

This video is showing how a black hole is made after a star collapses.
