"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.

Well, undiscovered doesn't mean undiscoverable. And they're slamming a lot of stuff together. Should be able to find these particles in particle accelerators, if they exist.
They're predicting the matter is there. We already have that galaxy [soylentnews.org] that supposedly doesn't show the anomalous velocity differences. A few more examples like that should be enough to rule out theories like MONDO and quantized inertia.

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.
It's like saying 'the galaxy should fly apart but it doesn't because I took a shit this morning'.
"Its presence is implied in a variety of astrophysical observations, including gravitational effects that cannot be explained unless more matter is present than can be seen. For this reason, most experts think dark matter to be ubiquitous in the universe and to have had a strong influence on its structure and evolution." https://en.m.wikipedia.org/wiki/Dark_matter [wikipedia.org]

Prove pooping isn't what keeps galaxies from flying apart...it's as good a theory as dark matter.

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.
