But where is warmth in all this, drich told us gravity depended on warmth.
Btw, gravity does in fact depend on warmth, if warmth I'd rigorously defined as the amount of thermal energy in the earth. BUT as certainly as drich knows jack shit about physics, the relationship between warmth and gravity is not what drich thinks. And in the real world many other higher order effects would influence the force of the pull of gravity, such as the complicated non-concentric mass distribution of the earth, the deformation of the earth by gravity of moon and sun, etc, FAR,FAR, more than the amount of thermal energy in the earth.
By E=MC^2, energy is mass, and warmth is the average kinetic energy of the molecules in the substance involved. So a warmer object does have more energy, and by equivalence more mass than a cooler but otherwise identical object. So a warmer object excerpts a slightly greater gravitational pull than a cooler one. But the amount of gravity caused by thermal energy is vanishingly small next to the gravity of the rest mass. No spacecraft has yet had its orbit gone meaningfully awry by its handler ignoring the thermal component of the earth's gravitational mass.
