Temperature-Dependent G and Black Hole Thermodynamics
One of the most enduring and persuasive results of one-loop quantum gravity calculations is the unexpected connection between black holes and thermodynamics. The work of Bekenstein1 and Hawking2 indicates that one may assign an entropy to the spacetime structure represented by the hole, given in the Schwarzschild case by Sbh = 1/4 A/G= 4 GM2 (1) where A is the event horizon area, M the mass, and I have used units with K = c = k = 1.
