Black holes are formed when stars, much larger than our own sun, collapse.
This creates an entity of extremely high mass and density.
This results in inconceivable gravity.
The gravity of black holes is in fact so much that even light cannot escape them.
This is why they are called black holes, devoid of any light.
There has been an immense amount of research on black holes in recent years.
But still we know very little about them.
The great scientist Stephen Hawking has contributed the most to the study of black holes.
His famous equation called the Hawking Radiation equation explains the phenomenon of black holes.
Black holes are indeed fascinating things.
