0 a type of radiation (= energy from heat or light that you cannot see ) that should be produced by a black hole (= a region in space where gravity is so strong that nothing, not even light, can escape):
Black holes lose mass by radiating energy in the form of Hawking radiation.
The black hole's event horizon radiates positive-energy particles, a phenomenon known as Hawking radiation.
Could the cosmic microwave background radiation be a form of Hawking radiation?
