Autodynamics, i.e., the melding of gravitation and particle theory. I went down that path starting from an Onsager approach. "The impingement of light in a gravitating body causes the frontal portions of mass to become more active. Leverage creates a mass gradient. The equation, dE = - dm/dr c**2, is the differential form of the mass energy equation. Then gravity becomes nothing more than a heat engine energized by impinging particles, whether they be "Q's" as I have coined them or the virtual particles used in Autodynamics. Gravity analogizes to a feedback control mechanism. Mass literally "walks" towards the heavier mass. Please ignore references to Einstein in the following because I realize you all don't care for him:
