New Theory Of Planetary Motion And New Formula Of Universal Gravitation

If the solar system is regarded as a moving mass point system, then both the planet m and the sun M move around the solar system mass center O. According to the motion law of the mass point system and the centripetal force formula of the curve, it can be determined through theoretical analysis and mathematical derivation: (1) Kepler's law of planetary motion contradicts the motion rules of mass point systems. (2) The universal gravitational force F between planet m and sun M. K is the new gravitational constant. The force F' on the object m in the inertial frame S'. In the formula, V' is the velocity of the object m in the inertial frame S', and u is the velocity of the inertial frame S' in the cosmic space reference frame. In addition, the author designed three new optical experiments based on the light interference theory to verify whether the principle of constant speed of light conforms to objective facts. Experiment 1. Using the new front and rear hole laser interferometer for verification; Experiment 2. Verification of using long and short optical path Michelson interferometers; Experiment 3. Verification of using a double-hole interferometer.

Abstract:

Our modern understanding of the heliocentric universe developed five hundred years ago. Since the time of Copernicus and Galileo, scientists have made major strides in understanding how gravity, stars, and planets interact. Gravity, Orbiting Objects, and Planetary Motion explains how early ideas have given way to sophisticated, proven theories about the universe. The book aligns with Next Generation Science Standards and also presents a look at what is next in the cutting-edge field of astronomy.

For long it has been accepted that Kepler 'proved' three empirical laws of planetary motion, and that Newton depended upon these in 'establishing' his law of universal gravitation. As Professor Wilson demonstrates, the truth is more complicated - but more interesting. The question of observational evidence therefore forms the theme of this volume. The first articles trace the evolution of Kepler's ideas and reconstruct the steps in his journey. Their conclusion is that observational error inevitably prevented any satisfactory direct verification of Kepler's first law so, as Kepler himself recognised, his results rested upon hypothesis. The final articles present a similar study of Newton's thoughts on gravitation and planetary motion: again, as Newton left it, the theory he propounded can be considered no more or less than a hypothesis. In between Professor Wilson examines the attitudes of mid-17th-century astronomers to Kepler's ideas, and in particular, the achievements of Jeremiah Horrocks: he died in 1640, at the age of only twenty-two, but his improvements in Keplerian astronomy were of great importance for Newton's future work.

The Feynman Lectures on Gravitation are based on notes prepared during a course on gravitational physics that Richard Feynman taught at Caltech during the 1962-63 academic year. For several years prior to these lectures, Feynman thought long and hard about the fundamental problems in gravitational physics, yet he published very little. These lectures represent a useful record of his viewpoints and some of his insights into gravity and its application to cosmology, superstars, wormholes, and gravitational waves at that particular time. The lectures also contain a number of fascinating digressions and asides on the foundations of physics and other issues.Characteristically, Feynman took an untraditional non-geometric approach to gravitation and general relativity based on the underlying quantum aspects of gravity. Hence, these lectures contain a unique pedagogical account of the development of Einstein's general theory of relativity as the inevitable result of the demand for a self-consistent theory of a massless spin-2 field (the graviton) coupled to the energy-momentum tensor of matter. This approach also demonstrates the intimate and fundamental connection between gauge invariance and the principle of equivalence.
