Well, yeah. We know for example that the coupling constant of the strong, weak and electromagnetic interactions are "running", i.e. they change depending on what energies the interacting particles have.

That's why we assume that those interactions are all part of one single, more fundamental interaction at very high energies. We already know that the electromagnetic and weak interaction combine into a single interaction at high energies, and it looks like the strong interaction will combine with that at even higher ones.
This doesn't say anything about how those couplings change with (cosmological) time, however.
