re: Interesting take on dark energy
Interesting work that one. Weird how much older the voids are than the galaxies due to the mass-density - makes sense when GR is involved, but no one thought to compute it before.
There's still dark matter, but perhaps not as much. Other GR theories have emerged on how "missing mass" could also be due to over-simplified computations of the relevant mass-energy tensors leading cosmologists down the garden path.
