Einstein's theory of general relativity predicts the existence of black holes: bodies dense that their gravity captures everything close by and prevents it from escaping. Many feel there is now overwhelming evidence that black holes exist and are common throughout the universe. The formation of black holes can be understood in a simple way. The parts of any body attract each other with a very tiny gravitational force. In its dense centre, these atoms bump into each other and fuse together in mini nuclear explosions. Although the gravitational pull of a single atom by itself is very weak, many atoms concentrated in a small space exert gigantic forces. These weigh a million or a billion times as much as Sun. The black hole at the centre of own Milky Way galaxy is three million times as massive as the Sun. Black holes exist and give rise to infinities, which suggests that general relativity is not an ultimate theory.
