TLDR: equilibrium is a beautiful simplicity and elegance that derives from alot more computational work than meets the eye. It is the convergence of two informational processes, harmonizing. It is not one informational process oscillating like magic. Chemists and computer scientists understand this, but social science has yet to dispense of this metaphysical crutch for equilibrium.

Physically, equilibrium has its natural evolution deriving from two informational processes, falling into themselves. The mixture exists not still, but phasing into each other at equal rates. the forward reaction is in opposite phase of the backward reaction.
