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

Their topics include probabilistic interpretations of quasilinear parabolic systems, new examples of Hawking radiation from acoustic black holes, spectral properties of the Neumann-Laplace operator in quasiconformal regular domains, two hydromechanical problems inspired by the works of S.
Even as ALS confined him to a wheelchair by the 1970s, Hawking began to contemplate the ideas behind the concept he's most famous for: Hawking radiation. In this process, black holes lose energy (and therefore mass) by interacting with virtual particles.
The next year he developed a theoretical argument that black holes emit radiation (later termed Hawking radiation).
By devising an equation (dubbed "Hawking radiation") that proved black holes have a temperature, it was proved that radiation could escape the black hole.
He hypothesized that black holes emit radiation-dubbed "Hawking radiation."
Stephen's discovery, known as Hawking radiation, held that quantum effects around black holes could cause them to radiate particles, and presents a challenge to classical theoretical physics, which had traditionally held that nothing can escape a black hole.
The scientist is accredited with the discovery of the phenomenon, which we recognize the Hawking Radiation, in astronomy....where black holes leak energy and fade into a void of nothingness.
Professor Brian Cox paid tribute saying: "in a thousand years' time, [physicists] will still be talking about Hawking radiation, they will be using his fundamental results on black holes.
He developed a theory of cosmology as a union of relativity and quantum mechanics, and discovered black holes leak energy - a phenomenon dubbed Hawking radiation.
Hawking Radiation, based on mathematical concepts arising from quantum mechanics, the branch of science that deals with the weird world of sub-atomic particles, eventually causes black holes to "evaporate" and vanish, according to the theory.
He also discovered that black holes leak energy and fade to nothing - a phenomenon that would later become known as Hawking radiation. Through his work with mathematician Sir Roger Penrose he demonstrated that Einstein's General Theory of Relativity implies space and time would have a beginning in the Big Bang and an end in black holes.
His works include the theoretical prediction that black holes emit radiation, often called Hawking radiation. Hawking was the first to set out a theory of cosmology explained by a union of the general theory of relativity and quantum mechanics.
