Once I factor in the relavistic attributes to my journey, we will be in agreement.

So it isn't ridiculous to assign an age to the universe once we factor in the relavistic properties relevant to the FoR that the age was calculated from, because once all these factors are considered properly, all are in agreement.

Am I getting there?
You're getting there.
