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.

    Which is what I'm saying: Quantum Inertia works as a better theory than dark matter, and he just got funding in the millions to work at it.

    To me, work at and fund something that actually seems to work, rather than a kludge that only works in certain situations but does not solve all situations in which it was invoked to solve.

    It. Is. A. Kludge, not a solution.

      You already had a journal about a galaxy where quantum inertia doesn't work (the one allegedly with no dark matter). And the theory does this weird circular argument where it talks about inertia in terms of acceleration without actually doing anything different from standard theory. My suspicion is that if we dug a bit, we'd find MONDO-style adaptions to make the theory fit observation - and in the present journal we don't actually know whether theory fits observation.
