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 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 ...
The Penrose singularity theorem is a theorem in semi-Riemannian geometry and its general relativistic interpretation predicts a gravitational singularity in black hole formation. The Hawking singularity theorem is based on the Penrose theorem and it is interpreted as a gravitational singularity in the Big Bang situation.
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.
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 ...
The Unruh temperature has the same form as the Hawking temperature T H = ħg / 2πck B with g denoting the surface gravity of a black hole, which was derived by Stephen Hawking in 1974. [7] In the light of the equivalence principle, it is, therefore, sometimes called the Hawking–Unruh temperature. [8]
If black holes evaporate via Hawking radiation, a solar mass black hole will evaporate (beginning once the temperature of the cosmic microwave background drops below that of the black hole) over a period of 10 64 years. [149] A supermassive black hole with a mass of 10 11 M ☉ will evaporate in around 2×10 100 years. [150]
