On Bekenstein and Hawking’s “Black Hole Thermodynamics”

More than fifty years ago, Hawking put forward a theorem that the area of a black hole (or 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, , is the “black hole’s temperature”. Again, with a thermodynamic way, Bekenstein “confirmed” Hawking’s idea that the gravitational acceleration, , is the “black hole’s temperature”. Based on these three “new concepts”, area entropy, thermal radiation and gravitational temperature, a new branch of astrophysics, namely, the “black hole thermodynamics” was established and developed very quickly. It is an inter discipline, relating to general relativity, theory of quantum fields, and thermodynamics-statistical physics. The authors of this article assert that, Bekenstein and Hawking’s three “new concepts” are all wrong, 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 academic circle.
