Principle of Dynamic Gravitation presents a revolutionary extension of Newton’s universal law of gravitation, offering a comprehensive framework that applies not only to planetary systems but also to galaxies and cosmic structures. This book addresses key astrophysical phenomena such as orbital evolution, precession, gravitational lensing, and the discovery of missing mass. It provides fresh insights into galaxy rotation curves, the formation of galactic and cosmic structures, and system interactions on a grand scale. By bridging the gap between classical and cosmic physics, this work redefines our understanding of gravitational forces in the universe.
