Very interesting but lambdaCDM reigns supreme right now - this is very new data and there isn't really anything to corroborate it yet so it might end up being a systematic error of some kind. Will keep my eye on it for sure.

Or doesn't have our universe an age at all?

Time doesn't exist for light, why should it then for our universe?

I say it's all water under the bridge. What's a dozen billion years anyways when it's already gone?
