Oh snap! Take that, dark matter!

"Dark matter cannot be used to fudge them because in order for dark matter to predict galaxy rotation it must stay spread out and therefore it cannot be squeezed into little wide binary systems."

His blog is an interesting read.
Dark matter is dying. RIP.

    No, by predictive I mean there is no formula, such as E=MC2 that can be used to predict anything to do with dark matter. It's just added there arbitrarily JUST to save GR.

    So? Welcome to epicycles. It's a real part of science, even if nobody likes it. Take a model that partially works and attempt to extend it via these sorts of tricks and perturbations to regions where it doesn't normally work, but isn't that far off. Here, it's just not that big a stretch. We know various sorts of dark matter exist and the models match observation with that dark matter. It's now a matter of either finding that matter or finding a theory that works better.
