That paper focuses on rotation curves, like all DM skeptics. I can only assume because this problem is understandable with high school level math. But that's neither the only nor the best evidence for DM. If your new hypothesis doesn't even mention the CMB power spectrum, it's not really worth listening, sorry. And to be taken seriously, it has to explain at least most of the data. DM does that, everything else does not.
