In physics, black hole thermodynamics [1] is the area of study that seeks to reconcile the laws of thermodynamics with the existence of black hole event horizons.As the study of the statistical mechanics of black-body radiation led to the development of the theory of quantum mechanics, the effort to understand the statistical mechanics of black holes has had a deep impact upon the ...
where is ADM mass of the black hole and N a are the conserved charges and a runs from 1 to n. The signature of the metric reflects the sign of the hole's specific heat . For a Reissner–Nordström black hole , the Ruppeiner metric has a Lorentzian signature which corresponds to the negative heat capacity it possess, while for the BTZ black ...
Black Holes and Beyond; An Answer to Everything; An extensive online companion site was produced to accompany the documentary. The online companion covers history of cosmology, unanswered questions and other topics related to the program. It was designed to function as both a supplement to the series and a stand-alone web piece.
A black hole with the mass of a car would have a diameter of about 10 −24 m and take a nanosecond to evaporate, during which time it would briefly have a luminosity of more than 200 times that of the Sun. Lower-mass black holes are expected to evaporate even faster; for example, a black hole of mass 1 TeV/c 2 would take less than 10 −88 ...

The premiere of the first episode attracted 1.9 million viewers, and was considered a success. [4] The second episode had 1.7 million viewers. [5] James Walton of The Daily Telegraph wrote a positive review of the first episode, saying that it "hadn't done a bad job of trying to explain advanced physics to the science novice," even if it was "extremely difficult stuff."
