Sinopsis

From the end of the last century, the thermodynamic theory of gravity has made great progress. Einstein equation was deduced by thermodynamics methods by Jacobson and Verlinde. In this work, we discussed the elliptic orbit motion using the language of thermodynamics. First, the difference between Newton's and Einstein's theories for gravity is analyzed. Then, the elliptical orbital motion is found to be a thermodynamic cycle, during which the energy of the gravitational field is converted into work carried by gravitational waves. If the gravity is weak enough that the zero order approximation of the general relativity, Newton's law of universal gravitation, is accurate enough, the endothermic process and the exothermic process will coincide with each other approximately on the T-S diagram, which means there is no energy loss. In this case, the elliptical orbits can be approximated as stable orbits.
