I'm a mere chemist, so I'm figuratively typing and ducking, as I ask this, but:-

If Dark Energy is increasing, then could this not be explained by the Gravitational Constant $G$ not being constant, but actually a value which could be decreasing.

Or, perhaps the $G$ Constant Changed, at @ 6 billion years ago when Dark Energy increased in value. Perhaps at 6 billion years ago the density / temperature, of the Universe, was the point at which the Universe went through a Phase Transition, as do Superconductors at a molecular / atomic level?

    Nope. It's safe to say that we thought of this. I mean, you have to assume that the scientists spending their whole life on the issue are going to think of the same things at least as another scientist spending 5 minutes on it. – Jim Feb 01 '23 at 14:39
  • It could be, but it entirely depends on what model of dark energy you're working with? – Song of Physics Feb 01 '23 at 14:44
