Hawking radiation
Save This Word!
noun
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

How to use Hawking radiation in a sentence
Hawking radiation for realistic black holes is a minuscule effect, and the bigger the black hole, the less radiation there is.
The new paper models the Hawking radiation for a collapsing star before it makes a black hole.
The temperature of Cygnus X-1 from Hawking radiation is roughly a billionth of a degree above absolute zero.
Hawking showed how that process works, which is why we call it Hawking radiation.
Scientific definitions for Hawking radiation
Hawking radiation
A form of radiation believed to emanate from black holes, emerging from the region just beyond the black hole's event horizon (from which no radiation can emerge). Pairs of virtual particles and antiparticles, created naturally in the vacuum fluctuation near the black hole, are split apart, one particle falling into the black hole and the other radiating away. The energy lost to such radiated particles is believed to come from the mass of the black hole.
