Anisotropic physics?
As far as I know, everything we think we know about distant conditions and processes -- as well as how distant and/or old they are -- is founded on the principle that physics is the same everywhere.
If not...
At the very least, the age of our universe is dependent on more variables than its apparent rate of expansion. At most... as you say, a hint that the fields are unified even if our math about them isn't, yet.
