What is Hawking Radiation?



What is Hawking Radiation?..

Answer / seema

According to quantum theory , black holes are not quite
black! Instead, they should glow slightly with "Hawking
radiation", consisting of photons, neutrinos, and to a
lesser extent all sorts of massive particles.

This is not observed, because the only black holes we have
evidence for are those with lots of hot gas falling into
them, whose radiation would completely swamp this tiny
effect. If the mass of a black hole is M solar masses,
Hawking predicted it should glow like a blackbody of
temperature


(6 x 10-8/M) kelvin,

so only for very small black holes would this radiation be
significant.
