Black Holes, Entropy and the Third Law

There would be a perfect correspondence between the laws of classical thermodynamics and black hole thermodynamics, except for the apparent failure of black hole thermodynamics to correspond to the Third Law. The classical Third Law of Thermodynamics entails that as the absolute temperature, T, approaches zero, the entropy, S, also approaches zero. This discussion is based upon part of the work published by the author in 1995 that demonstrated that the most general form of the classical Third Law of Thermodynamics is satisfied by treating the area of the inner-event horizon as a measure of negative-entropy (negentropy)
