Don't get too excited, this is a pretty fringe theory that doesn't really have experimental evidence. They were able to make some observations fit with their theory without dark matter yes, but not all of them. The tired light part in particular has a lot of contradictions with observation that they don't explain.

So interesting, but far from definitive.

Couldn't the same be said for the proof of dark matter?

No, dark matter is actually a great explanation for lots and lots of observations; the only problem with it is that we don't know anything about it other than that it is such a good explanation for these observations.

Generally for a new theory to be accepted, it needs to explain everything that the old theory did plus something more
