Z.I.P.P.E.D. Theory: Unifying Gravitation and the Speed of Light through Cosmic Equilibrium

Z.I.P.P.E.D. Theory: Unifying Gravitation and the Speed of Light through Cosmic Equilibrium Description:This manuscript presents the Zwanenburg Inverse Proportionality Principle of Equilibrium Dynamics (Z.I.P.P.E.D.), a scale-invariant framework unifying the gravitational constant ($G$) and the speed of light ($c$) as emergent properties of a single spacetime tension. By formalizing the Law of Cosmic Unraveling (Wet van de Kosmische Ontknoping), Z.I.P.P.E.D. provides a closed, mathematically consistent explanation for gravitational phenomena from terrestrial scales to galactic rotation curves—without invoking dark matter. The manuscript includes derivations of the cosmic acceleration scale, the Zwanenburg Radius, and the mechanical linkage between $G$ and $c$, alongside a complete set of appendices detailing empirical calibration, theoretical closure, and reviewer defense rules.
