See, I was going to say something here, but all the points I would have made have been covered already. So it's left to me to point out just how very little one is expected to question these sorts of entities in the course of an astrophysics B.Sc. "There's this dark matter, because it explains the observations, and it's not your place to ask what it actually is..." or something like is that pretty much sums up my undergraduate third year.
In this case, it could be a particularly nonluminiferous aether.
