Black Hole Thermodynamics
Hawking (1974) shows that black holes radiate and have a temperature, linking gravity, quantum theory and thermodynamics.
Open in the interactive tree →Building on Bekenstein's entropy idea (1972), the calculation implies that black holes slowly evaporate and raises the information paradox. It is the main clue and test case for any theory of quantum gravity.
