Hawking radiation

Hawking radiation

n.
A form of radiation believed to emanate from black holes, arising from the creation of pairs of subatomic particles in the space adjacent to the black hole, with one particle falling into the black hole and the other radiating away. The energy lost to such radiated particles is believed to cause the eventual disappearance of the black hole.

[After Stephen William Hawking.]

Hawking radiation

n
(Astronomy) astronomy the emission of particles by a black hole. Pairs of virtual particles in the intense gravitational field around a black hole may live long enough for one to move outward when the other is pulled into the black hole, making it appear that the black hole is emitting radiation

Black hole evaporation produces a more consistent view of black hole thermodynamics, by showing how black holes interact thermally with the rest of the universe.
Other subjects discussed include topological origins of the coupling constants hierarchy, semiclassical dynamics of black holes, black hole evaporation as a nonequilibrium process, and the dynamics of anisotropic universes.
It" we try to follow the process of black hole evaporation from beginning to end from the physics we know, we reach a contradiction," he notes.
