what is black hole?

Black Hole is a region of space having a gravitational field so intense that no matter or radiation can escape. That means the maximum density of particles is present inside the black hole . 
Even light can't escape from the attraction of black hole. 

Black hole is first detected in 1971 by an american Astronaut. But yet now there are no direct physical presence of black hole is discovered. The black hole is the imagination of a process and the great fact of aerospace!
