FORCE OF GRAVITATION DOES NOT EXIST.

If One calculates the kinetic and potential energies of the planets
relative to the rest of the universe, using the formulas
kinetic energy = m(2 pi L )^2/t^2 and potential energy = -G(M-m) m/L,
( THIS IS THE ONLY CORRECT METHOD, it explains the T.R.Young-
two slit interference pattern which includes the rest of the universe
).
One will find that they are of nearly equal magnitude but opposit in
sign.
One will also find that their sum is a constant, the equilibrium energy
for the particuoar planet.This is the energy that remains constant as
the universe expands. its potintial energy continually decreasing and
its kinetic energy continually increasing. Only at the orbital distance
will a small change of kinetic energy equal an opposite change of
potential energy.This is the total energy that requires no force , with
its necessary acceleration and change of totall energy, to maintain it
as a constant.No force of gravity is necessary to explain the motion of
the planets in the expanding universe. The planets motion around the
center of the rest of the universe at the specific distance L is the
equilibrium condition for constant total energy of the orbiting planet
in the expanding universe.
