Hawking radiation - Wikipedia

WebWe provide a simple way for calculating the entropy of a Schwarzschild black hole from the entropy of its Hawking radiation. To this end, we show that if a thermodynamic system loses its energy only through the black body radiation, its loss of entropy is always 3/4 of the entropy of the emitted radiation. This proposition enables us to relate ... WebFeb 7, 2024 · Consequently, an Earth mass black hole would absorb more energy from the CMB than it emits through Hawking radiation. Therefore in order an Earth mass black hole to evaporate, we need to wait for the universe to cool below 0.02 K. This itself will take a very long time (but one that is utterly insignificant compared to the total evaporation time). bsl now ltd https://neisource.com
