Black Hole in Space

What Is Black Hole?

According to the general theory of

relativity, a black hole is a region of

space from which nothing, including

light, can escape. It is the result of the

denting of spacetime caused by a very compact mass.

Around a black hole there is an

undetectable surface which marks

the point of no return, called an

event horizon.

It is called "black" because it absorbs all the light that hits it, reflecting nothing, just like a perfect black body in thermodynamics.

Under the theory of quantum

mechanics black holes possess

a temperature and emit Hawking

radiation through slow dissipation

by anti-protons.

A black hole can be inferred by

tracking the movement of a group

of stars that orbit a region in space.

Astronomers have identified numerous

stellar black hole candidates, and have

also found evidence of supermassive

black holes at the center of every galaxy.
