A black hole is an extremely dense celestial body which is believed to exist in our universe. THe gravitational force of a Black Hole is so strong that light can enter it but not escape.
The Black Hole Concept was developed by a German Astronomer in 1916, named Karl Schwarzschild. He based his studies on Albert Einstein's general theory of gravity.
The point when no matter can escape the gravitational force of a black hole is called the Event Horizon. You can only see a black hole when light is entering it, not any other time.
Black Holes are still a mystery to mankind which is why we don't know all the facts about Black Holes.
Black Holes are also called Neutron Stars.
