What we do know is that freely moving bodies form holistically balanced systems of angular momentum in which the measured motion of every one body is linked with that of each and every other. Is this non-local interconnection to be called 'action-at-a-distance' or 'ether'? Does it matter? Can nature care whether we choose to think of that nexus as 'gravitational', 'inertial', 'electric', 'magnetic', 'electromagnetic' or whatever? What difference can it make so long as the observed linking of movements is properly accounted for.
We demonstrate that angular momentum, which is the observational common factor in all the different orbital motions is sufficient in itself to explain those motions without the usual theoretical elaborations supplied by the likes of Newton, Faraday, Coulomb, et al.
