Hawking Radiation is some type of a radiation emitted by Black Holes. To understand it better we might need to get an idea about a black hole. Black hole is a collection of matter or antimatter that has been condensed so much to one point. So nothing can escape. Even the light. In The middle of the black hole there is something called singularity. That’s singularity holds the entire mass of the black hole. Around the singularity there is imaginary sphere called event horizon. Nothing can escape when it passes that point. Due to this strong pull a one particle of a pair of virtual particles can fall in to a black home. The particle that escape to the universe carries the energy. Due to this process black hole looses it’s energy. Eventually that leads to evaporate entire black hole.
