Thermo - Gravitational Equilibrium

Acknowledging that what is currently defined as ‘pressure’ should not have reason to exist without the existence of a gravity field, the connection between thermodynamics and gravity can be easily made clear. Comprehensive thermo-gravitational equilibrium conditions may be defined without raising any doubt about the validity of the conventional thermodynamic and gravitational equilibrium conditions, being the latter ones consistent with the spontaneous tendency, respectively, towards lateral disorder and radial order, jointly resulting from the existence of the gravity field. Therefore, in a whole system subjected to its own gravity field, or in any isolated large fraction of it, a thermal gradient would be associated at equilibrium to the pressure and density gradients.
