hawking radiation

الإنجليزية - الإنجليزية

تعريف hawking radiation في الإنجليزية الإنجليزية القاموس.

The radiation presumed to be given off by a black hole by quantum mechanical processes

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. 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 result in one particle's escaping the vicinity of the black hole while the other particle, of negative energy, disappears into it. The flow of particles of negative energy into the black hole reduces its mass until it disappears completely in a final burst of radiation
