Idk. My son once used standard knowledge of the quantum froth / particle / anti-particle pair production in vacuum to estimate the light pressure due to that production in great voids and came up with an answer that's off from standard cosmology by just a factor of two (i.e., this explained half the acceleration of the expansion of the universe). It's pretty easy to take assumptions like this and extrapolate. It's not clear that dark energy is obviously wrong, but it's weird because the universe presumably needs energy in order to accelerate its expansion, and... where's that coming from? The standard answer is: from the light traversing the universe (especially the great voids) which loses energy as the universe accelerates its expansion. But what is the mechanism by which that happens? I've yet to see such a mechanism proposed, and that is what makes Dark Energy weird.
I would not compare DE to religion though. It's DM that's a bit of a bridge too far for me, though even there it's hard to know yet.
Also note that timescapes is only about DE not DM. I don't think you'll find an explanation for the galaxy rotation curves anomalies in GR.
