Sounds speculative --although not necessarily in a bad way.
What's the evidence for the proposed change of the coupling constants? If the observational evidence is that this changing of the coupling constants explains certain observations related to very old galaxies and stars, would it be possible to infer other early Universe observations that could be performed to confirm this hypothesis?
