This research paper by Gerges Francis Tawadrous investigates the relationship between planetary velocities and their diameters, proposing that planet motion and velocity are functions of their dimensions and orbits. Key hypotheses include light motion's influence on planetary motion, with specific calculations demonstrating these relationships, particularly focusing on the interactions among Uranus, Pluto, and the Earth-Moon system. The author argues for a systematic design in the solar system's data, suggesting that various celestial interactions follow defined geometric principles.
