Definition of Black hole

Black hole

A Black hole in astronomy is a region of space having a gravitational field so intense that no matter or radiation can escape.
Black holes are probably formed when a massive star exhausts its nuclear fuel and collapses under its own gravity. If the star is massive enough, no known force can counteract the increasing gravity, and it will collapse to a point of infinite density. Before this stage is reached, within a certain radius (the event horizon), light itself becomes trapped and the object becomes invisible.
