On the black hole’s thermodynamics and the entropic origin of gravity

The effects of gravity on the Schwarzschild’s black-hole behavior is described on using the thermodynamic equations of state for contractile materials. Its entropy and temperature, obtained by using classical principles, reproduce the results derived from quantum field theories and statistical mechanics. The given results show that, by using the gravitational dynamics to reproduce the thermodynamic equation TdS/dx = Fgravity , there is no way to establish the entropic origin of gravity, because the results can be seen the other way around.
