Gravitation Understanding Gravitation through Planetary Motion Kepler was one of the first scientists to say something about gravitation and related force. His postulates mainly are written as follows : 1. All planets move in elliptical orbits with the sun at a focus. 2. The radius vector from the sun to a planet sweeps an equal area in equal time. 3. The square of the time period of a planet is directly proportional to the cube of the semi-major axis of the ellipse. Electromagnetic Galaxy Understanding Gravitation through Electromagnetic Energy All-stars contain a positive electric charge and planets, satellites contain a negative electric charge as the net charge. The force of gravitation is related to magnetic force between planets, stars, and dark matter and varies by some constant. The above force is responsible for the balanced motion of celestial bodies in space. Therefore, if we learn to absorb energy due to the forces mentioned, the motion in space woul...
