Ah. OK, in that case... > When Kepler found a spinning object theory which worked, it wasn't overfitting. Well, yeah, that's true, but the important thing about Kepler was not the fact that it was a "spinning object theory", it was the switch from a "circular theory" to an "elliptical theory". (Also the switch from geocentrism to heliocentrism, but that was Copernicus, not Kepler). This is the sort of thing that the supersymmetrists are hoping to achieve, but have not yet achieved, most likely because nature is not supersymmetric in point of actual fact.
