Mayer`s Formula for Black Hole Thermodynamics in Constant
... Black hole refers to hypothetical objects that astronomers have first imagined existed from the theory of relativity and quantum theory. The discovery of pulsars identified with neutron stars, whose existence had also been predicted by theory, made more credible the ”black holes” and gave the signal ...
