Hawking Radiation Stephen Hawking Formula
Hawking proposed in 1974 that subatomic particle pairs photons neutrinos and some massive particles arising naturally near the event horizon may result in one particle s escaping.
Hawking radiation stephen hawking formula. Hawking radiation reduces the mass and rotational energy of black holes and is therefore also known as black hole evaporation. A rudn university physicist has developed a formula for calculating hawking radiation on the event horizon of a black hole which allows physicists to determine how this radiation would be changed with quantum corrections to einstein s theory of gravity this formula will allow researchers to test the accuracy of different versions of the quantum gravity theory by observing black holes and. Hawking radiation radiation theoretically emitted from just outside the event horizon of a black hole.
Do black holes emit heat some time ago it was determined that black holes were attached to the second law of thermodynamics which means that entropy or the measure of disorder could only increase with time and therefore everything that has entropy must also have a temperature. 5 6 using the thermodynamic relationship between energy temperature and entropy hawking was able to confirm bekenstein s conjecture and fix the constant of proportionality at 1 4. He was the lucasian professor of mathematics at the university of cambridge between 1979 and 2009.
The next year in 1974 hawking showed that black holes emit thermal hawking radiation corresponding to a certain temperature hawking temperature. That concept which came to be known as hawking radiation explained how energy. Discovery of hawking radiation.
In 1974 long before stephen hawking was the famous cosmologist he became he developed his most influential theory. Stephen hawking s discovery and his radiation began with a very simple question. Hawking radiation sometimes also called bekenstein hawking radiation is a theoretical prediction from british physicist stephen hawking which explains thermal properties relating to black holes.
