Gravity is an effective atomic wind that blows towards the center of a large mass. The settling of protons and neutrons. Through a random walk the larger masses will tend towards the center of mass. The electrons will escape the high density quickly and push outwards with a positive divergence. The return of the electron to the higher density will require some degree of settling in a process that is like cooling or like voltage reduction. Both processes require that heat be shed.

Gravity may be modeled scholastically.Important the realize is that the electrons seem to have positive divergence compared with the negative divergence of the proton - neutron combination.

Relating divergences to the electrical and magnetic topics of flux will be a topic of a subsequent post.
