The definition of radiation hawking or Hawking radiation interesting to discuss. Hawking radiation has an understanding related to black holes or black holes. This theory of outer space has even become one of Stephen Hawking’s greatest discoveries ever.
Stephen Hawking himself is one of the most famous British scientists. He died after a 50-year battle with amyotrophic lateral sclerosis (ASL).
Throughout his career, Stephen Hawking has managed to create various theories and discoveries that are valuable to the world of science. One of them is the prediction of the existence of the unique radiation emitted by black holes.

What is Hawking radiation?
Black holes are still unsolved mysteries of the universe. Scientists are still looking for ways to uncover the secrets of black holes.
So far, black holes are known as event horizons or points of no return. Black holes are also known as monsters in time and space that can devour all objects and matter around them.
British physicist Stephen Hawking used quantum mechanics to predict the slowly escaping quantum particles from black holes, now known as Hawking radiation.

The beginning of the discovery of Hawking radiation
Around the 1970s, Hawking proposed that black holes aren’t completely “black.” The reason is due to quantum mechanics.
This black hole actually emits a small amount of black-body radiation because it has a non-zero temperature. This understanding of Hawking radiation therefore shows that black holes are indeed surrounded by “fluff”.
The fuzz is made up of particles that have escaped the pull of gravity. However, this point of view is very contrary to Einstein’s views.
Then, in 1974, Hawking said that black holes are not eternal and have a life cycle. The black hole will experience evaporation and then shrink because it emits radiation.

Fusion of two theories
Stephen Hawking has to prove the opinion he expressed earlier. To prove this, Hawking combines two hitherto impossible theories to align, namely quantum theory and relativity.
Black holes emit very strong electromagnetic radiation and gravitational fields and energy fluctuations. The vacuum forms pairs of particles and antiparticles in the area around the event horizon.
One pair of elements “falls” into the black hole and the other escapes as an emission. Then, through this process, the black hole loses its mass and energy.
A black hole’s rate of shrinkage will be proportional to its mass, so that the most massive mass becomes the strongest and slowest to “evaporate”.
Black holes have a mass equivalent to that of the Sun and have a lifetime of millions to billions of years before finally disappearing by “evaporating”.
Hawking’s definition of radiation shows that anything that enters this black hole will leave behind information around it. Hawking revealed that black holes actually have halos of “soft hair” to store information. (R10/HR-Online)
