I didn't see anything in the paper about the rotational speed of galaxies. Was that accounted for?

Modified Newtonian dynamics attempts to account for that.

Or the effect we see on gravitational lensing that is accounted for by "dark matter"? I don't see how that could be explained by "light losing energy"...
