I get your point, but "So far, dark matter/dark energy are in remarkable alignment with observations." is not in accord for "whatever it is that causes... <our observations>". It would be a tautology at that level, equivalent to saying "our observations are in accord with our observations".
- taylodl 2y agoDark matter/dark energy work in the existing framework of GR and align well with observations. That's why they're so heavily favored. It's simple. Saying the laws of physics may be different in different parts of the universe is a statement that so far can't be substantiated, and we've been trying for over a hundred years now, is far more problematic. That's a dire option that we don't desire to pursue unless we're absolutely forced to - and we're not being forced to. Between the two options we're going to stick with dark matter/dark energy until evidence suggests otherwise, or until a better, and simpler, idea comes along.
