Everyone heard the word "BLACK HOLE". But many of them don't know why it is named as black hole ? and whether it is a hole or place.?
why it is named as Black hole?
Black hole is a place in space where the gravity is very much strong even light can never escape from the black hole due to the strong gravity. when the sun light is passed to the black hole it cannot reflect the light and it become invisible. so,it is named as black hole.
If human enter into the black hole it pulls the human due to the strong gravity. so, human can't escape from that.
How it is formed?
Black holes are formed due to the collapse of massive stars.
Types
It has three types based on their size and shapes.

Types
It has three types based on their size and shapes.
primordial
It is the smallest one because it is smaller in size but the mass is very large. Scientist says that it has formed in the early universe, soon after the big bang.
Stellar
It is medium in size when compared to primordial. Its mass is 20 times greater than the mass of the sun.
Supermassive
It is the largest one . Its mass is greater than 1 million suns and it is present in the center of the milky way galaxy called as sagittarius.
