Do galaxies in the early Universe with declining rotation curves count as evidence against dark matter ? My Master's project supervisor from back in the day thinks so. Haven't seen in him years so it's good to know he's still active, but I don't agree with the speculations here. This latest paper simply doesn't present a fair comparison between simulations and observations; there are anyway too many variables at work to draw any conclusions without trying much harder to disentangle everything.
