Hawking radiation — is a thermal radiation with a black body spectrum predicted to be emitted by black holes due to quantum effects. It is named after the physicist Stephen Hawking, who provided a theoretical argument for its existence in 1974, and sometimes also… … Wikipedia

Hawking radiation — Radiation theoretically emitted from just outside the event horizon of a black hole. Stephen W. Hawking proposed in 1974 that subatomic particle pairs (photons, neutrinos, and some massive particles) arising naturally near the event horizon may… … Universalium
Geroch energy — The Geroch energy or Geroch mass is one of the possible definitions of mass in general relativity. It can be derived from the Hawking energy, itself a measure of the bending of ingoing and outgoing rays of light that are orthogonal to a 2 sphere… … Wikipedia
