WebThis is the Hawking temperature equation that we will heuristically derive using three di erent ways in the following sections. Finally, it is important to emphasize that the argument developed in the two previous para-graphs shows us that the energy of Hawking radiation depends directly on the intensity of gravity (tidal forces) on the horizon. WebThe value of Tmax ∼ 1032 K −1/2 is exorbitantly large to be of any use, or so it seemed at least for a long time. Ten years after Sakharov’s result, Hawking derived semi-classically the temperature-mass (M) relation for the evaporation of black holes, T = 1/(8πGN M) = m2Pl /(8πM), with the spectrum of black body radiation [2, 3].
