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]. WebMar 28, 2024 · Rate of Radiation from a Black Body We can convert the formula for the energy density to the intensity of the radiation by considering the conservation of energy in electrodynamics.
