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 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 ...
The Thorne–Hawking–Preskill bet was a public bet on the outcome of the black hole information paradox made in 1997 by physics theorists Kip Thorne and Stephen Hawking on the one side, and John Preskill on the other, according to the document they signed 6 February 1997, [1] as shown in Hawking's 2001 book The Universe in a Nutshell.
See Stephen Hawking through the years: Acoustic black hole. To test this prediction, Steinhauer created an analogue black hole using extremely cold atoms trapped in a laser beam. When he applied a ...
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 ...
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 the 1970s came Stephen Hawking's startling prediction of black hole evaporation, powered by quantum fluctuations near the event horizon. [1] Toward the end of the text, Thorne deals with the much more speculative question of the nature of the core of a black hole; the so-called gravitational singularity predicted by Einstein's field equations.
Stephen Hawking provided a ground-breaking solution to one of the most mysterious aspects of black holes, called the "information paradox." Black holes look like they 'absorb' matter. Every time a ...
