But this actually the nature of Newton’s proof of Gravity which numerical is much more predictive than anything which you have produced. It is now clear to me that the variability in planetary orbits is essentially simple harmonic. Where Newton fails down is that whilst he produces a model there is a complete lack of determinism in his model. His problem and mine is that the Gravity of Planets and the Gravity that we experience at the Earth’s surface is not really the same case. The falling Apple never explained the orbit of the Moon. His mathematical model of the Gravity is ultimately a false model and that becomes apparent under certain situations. Einstein’s fundamental error is that he tried to explain the Anomaly rather than making a root and branch reappraisal of Newton, so he ended up with a MOND, which is based on useful insight but is a mathematical disaster area. No fundamental problem is ever that complicated, and solutions must never be that contrived.
