Hawking Radiation How black holes evaporate and Explode Explained

Hawking radiation,Black-Hole Evaporation and black hole explosions! Stephen Hawking theorized that a black hole may not be so black. He showed that when you apply the laws of quantum mechanics to classical physics, you find that they shine. They give off photons. How is this possible given that nothing escapes from black holes?

In classical physics, the mass of a black hole cannot decrease, it can either stay the same or increase. To Stephen Hawking and others, this idea looked similar to the 2nd law of thermodynamics which is, “In any natural process, the entropy of a closed system always increases or remains constant, it never decreases.” Similar to the 2nd law, there are also ways to state the other 3 laws of thermodynamics such that they are true for black holes as well.

In 1972, physicist Jocob Bekenstein, proposed that the surface area of a black hole is its entropy. The larger a black hole is, the more stuff it has consumed. Since everything it consumes has information, the greater the entropy of the system. Why? Because the more disordered a system is, the more information is required to describe it.

The analogy with thermodynamics suggest that black holes are a thermal body. In thermodynamics, there is something called a black body, which doesn’t transmit or reflect any radiation, it only absorbs it. A black hole, too, is something doesn’t transmit or reflect any radiation. If a black hole can be thought of as a black body, then it must have a temperature, because all black bodies have a temperature, which means it must shine.
