On Bekenstein And Hawkingâs Black Hole Thermodynamics
Abstract
Xinyong Fu and Zitao Fu
More than fifty years ago, Hawking put forward a theorem that the area of a black hole or of some black holes never decreases. Bekenstein immediately followed him with a new idea that the area of the event horizon is “the black hole’s entropy”. Soon after that, Hawking “verified” that the event horizon of a black hole emits “thermal radiation” and the gravitational acceleration there, represents the “black hole’s temperature”. Again, with a thermodynamic derivation, Bekenstein “confirmed” that the gravitational acceleration, is really the “black hole’s temperature”. Based on these three new concepts, i.e., “area entropy”, “thermal radiation”and “gravitational temperature”, a new branch of astrophysics, namely, the “black hole thermodynamics” was born. The authors of this article assert that, Bekenstein and Hawking’s these three “new concepts” are all false, the event horizon of a black hole has no any such thermal characteristics, and the “black hole thermodynamics” is just a fairy tale in the history of physics.
