A simple way to understand the universe, remember this.

For any matters M1 and M2 at distance R, there are two fundamental forces constantly at work.

1. Universal attraction force/gravity F=G x M1M2/R^2.

2. Universal repulsion force/levity   F=Ke x Q1Q2/R^2. Q1 is the total charge of line of sight electrons on the surface of M1, Q2 is  the total charge of line of sight electrons on the surface of M2.

These two forces rule the universe. Respond for star formation, stable orbit, light, radiation, induction, quantum entanglement, all nature phenomena.
