Referring to Nottale's Theory of Scale Relativity (http://luth.obspm.fr/~luthier/nottale/arIJMP2.pdf), I've been reading an awful lot about this theory and it seems to present, in my opinion, the best candidate for a unifaction of quantum mechanics and general relativity. The postulates of the theory are that the laws of physics apply equally regardless of coordinate system or scale. It also postulates that the speed of light is invariant in all coordinate systems and scales, and that there exists a minimum measure of distance/time, which is the Planck Length / Time, also invariant in all coordinate systems and scales. The paper suggests that the schrodinger equation, the uncertainty principle, and many other aspects of QM flow from this, resolving the "quantum/classical" threshold problem. Other papers by the same author claim to resolve the renormalization problem of QFT, and to provide the framework for quantum gravity. I'd like to get the experts' thoughts on this theory. Does it have any obvious failings? Why has it not gotten more attention?
