Experimental evidence on the widely different scales of the muon, nanometers, the human body, kilometers, and spiral galaxies is cited in confirmation of the easily theoretical prediction that 4 dimensional geodesics are a consequence of quantum holography for describing the behavior i.e. the invariant pathcurves, of objects. A quite independent theoretical derivation is quoted that predicts that general relativity holds on all macroscopic scales, i.e. in a context of the physics of Galileo and Newton, in further support, and where analysis of the known data in respect of the matter distribution in spiral galaxies, and the theory, correspond to a Universe in which matter has a self-similar or fractal distribution of dimension 2, exactly as is the case for quantum mechanics. ©1999 American Institute of Physics.
