The strangeness of Newton’s gravity equation is that it only deals with two bodies and no more. Just as strange as Coulomb’s Law that describes the force between two electrically charged bodies, with the difference being that Coulomb’s law deals with both attraction and repulsion while Newton’s only attraction. Both equations are of the form F=Constantxb1xb2/d^2. In gravity’s case b is the weight of the body compared to the earth, and is always positive; there is no such thing as a negative weight, if such a force can be measured in the first place. It easily follows that for the Coulomb Law b is the electric charge on the body, either positive or negative. “d” is the distance between the two bodies, in this case squared.
(As an aside, one could write computer code to numerically predict the three body problem but it is the nature of computer coding that each line of code introduces the time factor as a result of precedence, since parallel instantaneous numerical calculation is not possible. Hence the probable explanation why 3-body modelling evolves into chaotic motion. Gravity occurs instantaneously and this cannot be modelled by computer code).http://lhcrazyworld.wordpress.com
