Yes, the author appears to have overcome some limitations in existing models of galaxy rotation that incorporate gravitomagnetic effects (yes, others have thought of this before unlike Scott Locklin suggests and the paper even cites them). The claim is that these existing models were over-simplified to make them solvable: the less-simplified model proposed in this paper is much harder to solve but the author is an expert in mathematically similar effects in magnetohydrodynamics and appears to have found a solution. There are other astronomical observations that we still don’t have as good an explanation for (e.g. certain gravitational lensing observations) but this is a step in the direction of being able to dismiss the need for dark matter from our cosmological theories.
