I believe I can prove that such a solid doesn't exist, because if it did it leads to perpetual, motion as the solid could not remain still in any position on a horizontal surface once it is set in motion, and that is against the first and second law of thermodinamics. My question is if there is a mathematical proof without resorting to physics
