#Black Hole
Black holes are produced by huge stars. They are called black holes rot because there are real holes in space but because they cannot be seen as there is no light coming out of them. When after burning for billions of years stars reach the cnd of their lives their energy disappear. The burning core becomes very small like a pinpoint but its weight is as much as a star. It also has tremendous gravity and this gravity pulls towards it everything that comes ncar it. Although black holes cannot be seen through telescopes their presence can be identified. They are like gigantic magncts in space.
