The velocity of the Earth around the Sun and its corresponding mass are used in a standard centripetal force equation to match what Isaac Newton calculated with the Universal Law of Gravitation in 1687. Electromagnetic calculations are used to prove that electromagnetic forces are an insignificant contributor to the centripetal force or gravity, but do provide the bending force for the planets to maintain a circular orbit around the Sun. It is thus proven using classical physics that the force of gravity is a simple centripetal force with a very small electromagnetic force contribution. 展开更多

The paper Connecting Newton’s G With the Rest of Physics-Modern Newtonian Gravitation Resolving the Problem of “Big G’s” Value derived the value of the gravitation constant “Big G”, G of Newton’s Law of Gravitation, directly from other physics fundamental constants but left it to a subsequent paper to experimentally validate the derived G. The present paper performs that validation by examining various past experiments intended to measure “Big G”, in each case determining the acceleration, ag, as found per Einstein’s General Theory of Relativity versus per Modern Newtonian Gravitation for that case. The ratio of those two times the reported measured “Big G” value yields a result identical to the G determined from the derived formulation for G, within the error range of the reported measured “Big G” measurement. That thus validates the correctness of the derived formulation for G. The next important issue, what causes gravitation, how does the effect take place, is addressed and resolved in the paper The Mechanics of Gravitation-What It Is;How It Operates, which is available in this journal. 展开更多

As a simplified, idealized understanding of a physical system the General Relativity model has been highly successful in its gravitational role. However, it fails to address the problem of sufficiently precise measurement of “Big G”, the Newtonian Gravitation Constant, and has failed to obtain connection of “Big G” to the rest of physics. Because “Big G” arises naturally from Newton’s treatment of gravitation, this paper elaborates the Modern Newtonian Model of Gravitation and through it resolves the problems of “Big G” at which General Relativity has failed. Specifically: The causes of the problems in measuring “Big G” are resolved, “Big G” is connected to the rest of physics, and a sufficiently precise value of “Big G” is obtained by calculation from other fundamental physical constants. The companion paper The Experimental Data Validation of Modern Newtonian Gravitation over General Relativity Gravitation, which is available in this journal, publishes the results of this paper’s “Part V—Testing the Hypothesis and the Derivation”. 展开更多

From a start of only the limitation on the speed of light, the necessity of conservation, and the impossibility of an infinity in material reality, the present paper presents a comprehensive development of the mechanics, the operation of gravitation. Experience shows that everything has a cause and that those causes are themselves the results of precedent causes, and ad infinitum. Defining and comprehending the causality or mechanism operating to produce any observed behavior is essential to understanding or explaining the behavior. The behavior of gravitation is well known, described by Newton’s Law of Gravitation. But what gravitational mass is, how gravitational behavior comes about, what in material reality produces the effects of gravitation, is little understood. The extant hypotheses include Einstein’s General Relativity’s bending of space, efforts to develop “quantum gravitation”, and attempts to detect “gravitons”. None of those addresses the cause, the mechanism of gravitation. As demonstrated in the present and its prior papers, gravitation is an outward flow from gravitating masses. That means that by manipulating that flow gravitation can be controlled. The procedure for obtaining such control and the design for several various applications are presented in the paper Gravitational and Anti-gravitational Applications which is available in this journal. 展开更多
