What is Hawkings Radiation?

In 1974,  a young scientist thinks of a theory while he was on his bed trying to sleep. He confirms it with a friend and after connecting the quantum theory with Einstein's general relativity was he able to prove it. The name of that cosmologist was Dr Stephen Hawking who is the greatest scientist of our era and he discovered Hawkings Radiation.


Hawkings radiation tells us how a Black Hole dies slowly losing its mass and dissolving into nothingness. It gave us inspiration and hope for shooting the first picture of a black hole.

Hawkings Radiation states that a black hole having such a high gravity can lose mass and eventually die by radiating radiation and gamma rays.

 All matter has its anti in this universe and their meeting leads to the annihilation of that practicle. This we were talking about when they meet at normal circumstances (Vacuum). But what if they meet inside or near a black hole? The answer to this question is that the gravity of the black hole will attract the negative particle towards it which will give time for the other particle to escape as a result a black hole emits radiation which cannot be seen by naked eyes but it can be detected by powerful radio telescopes. This is called Hawkings Radiation.
