Hawking radiation is black body radiation released outside a black hole's event horizon due to quantum effects according to a model developed by Stephen Hawking in 1974. [1] The radiation was not predicted by previous models which assumed that once electromagnetic radiation is inside the event horizon, it cannot escape.
In physics, black hole thermodynamics [1] is the area of study that seeks to reconcile the laws of thermodynamics with the existence of black hole event horizons.As the study of the statistical mechanics of black-body radiation led to the development of the theory of quantum mechanics, the effort to understand the statistical mechanics of black holes has had a deep impact upon the ...
In equations, Hawking showed that if one denotes the creation and annihilation operators at a frequency for a quantum field propagating in the black-hole background by and † then the expectation value of the product of these operators in the state formed by the collapse of a black hole would satisfy † = / where k is the Boltzmann constant ...
In 1974, Stephen Hawking predicted that black holes might not be the bottomless pits we imagine them to be. According to Hawking's calculations, some information might escape black holes in the ...
In 1974, Stephen Hawking made one of his most famous predictions: that black holes eventually evaporate entirely.According to Hawking's theory, black holes are not perfectly "black" but instead ...
In 1974, Hawking predicted that black holes might not be the bottomless pits we imagine them to be -- and now, there may be evidence to support that theory.
1974 — Stephen Hawking applies quantum field theory to black hole spacetimes and shows that black holes will radiate particles with a black-body spectrum which can cause black hole evaporation 1975 — James Bardeen and Jacobus Petterson show that the swirl of spacetime around a spinning black hole can act as a gyroscope stabilizing the ...
Stephen Hawking never stopped trying to unravel the mysteries surrounding black holes -- in fact, he was still working to solve one of them shortly before his death. Now, his last research paper ...
