A black hole is and object with a gravitational force so high and no matter or radiation can't escape from a black hole.
There are back holes catagarized as, Supermassive,Intermidiate and micro black holes. I don't know how much is discovered now.

Black hole are so dense and have such gravity that they do not let even light to escape. This is because they have higher escape velocity than light.
A scientist(I don't exactly remember his name but I know its near the Second World War) stated the existance of black holes with the help of a blast of bomb.
Black holes cannot be easily destroyed by using any external source and it has such gravity that anything can never get near it. So it's difficult to find any black holes.
They are black in colour.

A black hole is at the center of every galaxy. Since there are millions of gallaxies, there are millions of black holes.

There is one in the middle of every Galaxy. That is what supplies the gravity that keeps every thing in orbit.
