I will explore the possibility that the couplings describing the strengths of the Standard Model gauge forces take different values at very early times.  As I will show, such a scenario is typically consistent with current observations if the variation happens early enough, and can cause us to radically rethink processes such as dark matter production or the generation of the matter-anti-matter asymmetry.
