Maybe the universe expanded differently when it was younger? Maybe the laws of physics change over time? There's no reason they have to be static. We assume that they are, but over timescales that big, could we detect the difference? (Or maybe we're just beginning to, with the JWST).
I'm the opposite of that guy from the A-Team. I *like it when a plan doesn't come together - because that's where the interesting stuff happens.

Yes, and there are still two (at least) schools of thought/calculations regarding the expansion rate of the universe, and their margins for error don't overlap, so there would appear to be something being missed somewhere.
