Abstract: | Although the question of the unification of the gravitational and electromagnetic interactions has been obscured by the unification of the electromagnetic and nuclear interactions, SU(2) gravitational gauge degrees have been recently unified to the U(1) electromagnetic degrees. If the resulting tracks of charges which mediate the unifying Yang-Mills field are assumed to induce a (dilation) scale invariance on the space-time geometry, the decoupling of these long range interactions, which takes place via a U(1) symmetry (periodic time) break, could be related to the onset of an initial singularity and origin of (linear) time. |
