Black holes in quantum gravity center of applied space. Due to the circumstances of a great astrophysicist passing away, the author has decided to derive in an elementary manner entropy and temperature of black holes without using the quantum field theory, the string theory or negative energy particles, even without using complex numbers. Hawking radiation is blackbody radiation that is predicted to be released by black holes, due to quantum effects near the black hole event horizon. Hawking radiation, sometimes also called bekenstein hawking radiation, is a theoretical prediction from british physicist stephen hawking which explains thermal properties relating to.

However, stephen hawking calculated that black holes actually radiate quantum mechanical particles. In 1974, hawking shocked the physics world by showing that black holes should in fact thermally create and emit subatomic particles, known today as hawking radiation, until they exhaust their energy and evaporate completely.
