SUBJECT: GRAVITY IS NOT A FORCE
PLANETS ORBIT THE SUN AT A SPECIAL RADIUS L TO CONSERVE TOTAL ENERGY. THE FORCE OF GRAVITY IS AN ILLUSION Copyright 1984-2005 Allen C. Goodrich ISBN 0-9644267,LIBRARY OF CONGRESS CAT.CARD NO.94-90554
For a particular value of mass m ( say the earth ),relative to the rest of the universe M-m there is a value of orbital distance L at which the total energy is a constant. In the absence of a total energy change the orbital distance will remain constant.No force of gravity is necessary to maintain the orbital motion
Based on the modified first law of thermodynamics "The total energy of the universe is a constant", ((total kinetic (mass) energy plus total potential energy is a constant)). . Planets, moons, and electrons are normally in equilibrium orbits where the total energy is constant. The orbital distance L of this equation is the necessary result. m(2 pi L)^2/t^2 + G(M-m)m/L+ X e(2 pi L)^2/t^2 + Z e^2/4 pi E_o L = a constant
From this equation (in the absence of a charge)
Delta m (2 pi L)^2 / t^2 = - Delta G (M-m)m/L follows mathematically POTENTIAL ENERGY = G(M-m)m/L (m at a distance L from M-m). KINETIC ENERGY = m(2 pi L)^2/t^2 (orbital motion at radius L from M-m). G= Gravitational constant; M = total energy of the universe (or effective universe,roughly the earth plus planets) ; m = mass in question, such as the earth.. t = time ; L = mean orbital radial distance. This is the only value of radius L where no change of total energy will occur if the value of L changes. Constant total energy fixes the orbital radius L. Orbital motion, at radial distance L, conserves total energy. Force of gravity isn't needed to explain orbital motion. .
