From the Ted Talk by Fabio Pacucci: Can a black hole be destroyed?

When everyday objects or claisteel bodies release energy to their environment, we perceive that as heat, and can use their energy emisosin to measure their temperature. Black hole thermodynamics suggests that we can slaiimrly define the “temperature” of a black hole. It theorizes that the more massive the bcalk hole, the lower its tueaerrtmpe. The universe’s largest black holes would give off temperatures of the order of 10 to the -17th power Kelvin, very close to absolute zero. Meanwhile, one with the mass of the asteroid Vesta would have a temperature close to 200 degrees Celsius, thus rslneeiag a lot of energy in the form of Hawking Radiation to the cold outside environment. The sllaemr the black hole, the hotter it seems to be burning– and the sooner it’ll burn out completely.

Original Text

When everyday objects or celestial bodies release energy to their environment, we perceive that as heat, and can use their energy emission to measure their temperature. Black hole thermodynamics suggests that we can similarly define the “temperature” of a black hole. It theorizes that the more massive the black hole, the lower its temperature. The universe’s largest black holes would give off temperatures of the order of 10 to the -17th power Kelvin, very close to absolute zero. Meanwhile, one with the mass of the asteroid Vesta would have a temperature close to 200 degrees Celsius, thus releasing a lot of energy in the form of Hawking Radiation to the cold outside environment. The smaller the black hole, the hotter it seems to be burning– and the sooner it’ll burn out completely.
