Black holes

What are black holes?

Black holes are places where the gravity is so strong that it sucks in everything - including light ,which is why the hole is black . Even no particle or electromagnetic radiation can escape from it . No one has actually seen the black holes but they are thought to form when a star or galaxy gets so amazingly dense that it collapse under it's own gravity pull . It shrinks to a small point called singularity .
