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”…
Not an astronomer but if I read the article correctly the observations gathered about galaxies rotating and colliding would be explained instead by regional changes in what were previously assumed universal constants, which would be very interesting if true but 1 paper isn’t consensus yet
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.
