Ah yes, the “cosmological principle” that everything averages out to be basically the same everywhere over large distances. It makes sense that this principle would need to be violated in order to eliminate dark energy. One of my favorite sci fi concepts is a universe where the cosmological principle was false.

Good news, the cosmological principle is almost certainly false since it leads to absurd results like dark matter and dark energy! Or if it was true once (CMB-era) it sure as shit ain't true now.

  Neither of those ideas are absurd.

    To you, maybe. But I find the idea that enormous chunks of the mass-energy in the universe is totally noninteracting unconvincing.

Note that this can also be distances in time, rather than just space.

> One of my favorite sci fi concepts is a universe where the cosmological principle was false. As it stands now, the cosmological principle seems false at every scale we look (with confidence decreasing in falshood slightly decreasing as scale gets larger). So that doesn't seem to be a "sci fi" concept, just a "sci" concept.
