ZIPPED: A Causal-Mechanical Derivation of Galactic Equilibrium Without Dark Components

This manuscript presents the completed ZIPPED framework — a causal-mechanical derivation connecting the speed of light and gravitational dynamics, eliminating the need for dark matter and dark energy. It introduces a finite causal response factor governing galactic rotation curves and cosmological redshift, explaining a universal 1.7% baryon-causality deviation as a structural equilibrium effect.This version is the definitive foundational manuscript for the ZIPPED theory by Michel Zwanenburg, January 2026.
