  • A dynamical model for varying light velocity in cosmology is developed, based on the idea that there are two metrics in spacetime. One metric gµ� describes the standard gravitational vacuum, and the other ˆµ� = gµ� +� µ � describes the geometry through which matter fields propagate. Matter propagating causally with respect to ˆµ� can provide acausal contributions to the matter stress-energy tensor in the field equations for gµ�, which, as we explicitly demonstrate with perfect fluid and scalar… CONTINUE READING
