In calculating the motion of the earh around the sun and around the centre of the Milky Way, the methods of the classical three particle problem can be applied with the new universal law of gravitation that replaces the one attributed incorrectly to Isaac Newton and inferred and introduced to Newton by Robert Hooke. So this will be the next stage of UFT219. A computer is needed for the classical n particle problem, again with the new law of universal gravitation. It becomes instantly clear that an infinite number of new orbits await discovery, both theoretically and experimentally. The solar system is an n particle problem of gravitation as is well known, and the moon earth sun system is a three particle problem. So I will commence a literature search on these methods.
