WebOct 19, 2024 · Professor Hawking believed that the fate of BHs was to evaporate out of existence, and also found that the holes have a temperature. For ordinary objects, the temperature could be due to the motion of microscopic constituents of the system. For example, molecules in the air have a temperature that is proportionate to their motion.
