> maybe the discrepancy that dark matter was invented to explain will simply disappear when more accurate astronomical data including the fainter stars becomes available
FWIW, that would be a much more surprising result than anything to do with dark matter. We can see "faint stars" just fine in the near field. What you're positing here is that somehow "faint" stars in the farther universe behave in notably different ways than they do in the Milky Way, which is exactly the kind of theory you're arguing against.
No, a few confusing results isn't going to throw dark matter out. It's too strong a signal, and too hard to explain via classical means (I mean, it's not like astronomers haven't tried!).
