WebDec 14, 2015 · The temperature of a black hole cannot be negative. The temperature is given by: $$ T = \frac {\hbar c^3} {8\pi kGM} \tag {1} $$ and obviously this cannot be negative as all the quantities on the right hand side are greater than zero. However the specific heat is negative and I wonder if this is what you are thinking of.

WebThe Hawking temperature (Hawking, 1974) is the black body temperature at which a black hole emits radiation due to quantum effects close to the event horizon. BLACK HOLE ENTROPY. The second law of classical … WebApr 11, 2024 · Gradually, it decreases as time goes on and eventually vanishes. Thus, the Stefan-Boltzmann law tells us that the black hole temperature, defined by the emission rate of the black hole energy, starts from zero temperature and reaches a maximum value at a critical time, and finally vanishes. Webe. Hawking radiation is theoretical [1] black body radiation that is theorized to be released outside a black hole 's event horizon because of relativistic quantum effects.
