Equilibrium Theory: Unification of Newtonian Physics and General Relativity using the wave equation

Here, I demonstrate that Newtonian and General Relativity mathematical frameworks are accurate mathematical approximations of a novel theory, the Equilibrium theory. Equilibrium theory asserts that existence is a continuous differential energy density structure, composed of compressed space-time (i.e. Mass) and stretched space-time (i.e. light) along with surrounding differential space-time (i.e. space); thus it is accurately represented using the wave equation, which is a mathematical framework that describes the dynamics of continuous structures.
