WebHawking1 predicted that a black hole should radiate with a temperature T5\g/2pkc, where g is the gravitational accel-eration at the surface of the black hole, k is Boltzmann’s constant, and c is the speed of light ~the Hawking effect!. The radiation results from the effect of the strong gravitation on the vacuum field.
