A black hole as a simple definition is a place in space where the gravitational field is so intense that nothing, even radiation, can escape. It has the power to tear the star apart as it pulls it toward itself. It is said that there may be a huge number of black holes in the universe. Quite a number of study is undergoing by researchers.
The idea of black holes was rediscovered in 1916 after Einstein published his theory of gravity. A well-known fact is that the milky way has 100 million black holes. Another amusing fact about the black hole is that til X-Ray astronomy was used, the first black hole wasn’t discovered.
