Mainstream theoretical physics needs to take a long hard look at itself. I've just read an article about Lisa Randall's new suggestion that dark matter killed the dinosaurs and after collapsing in a tangled heap of laughter I realised that this perfectly captures the attitude of mainstream theoretical physics: the extrapolation of untested and possibly untestable hypotheses into a regime where you are unlikely ever to be proven wrong, like the interior of black holes, the first millisecond after the big bang or the age of the dinosaurs. It is the physics of the unimaginative and cowardly.
Dark matter is like a universal plaster for any anomaly. For galaxies stick the invisible stuff freely onto your equations in a halo. For the flyby anomalies put it in a thin disc, for the dinosaurs it is a layer (I refuse to look at the details, like I refuse to read up on ghostology). There's a useful idea called Russell's teapot (pointed out to me by DaKangaroo on twitter). Bertrand Russell said that if someone claims there's a teapot orbiting the sun between Mars and Jupiter the onus is on them to prove it, certainly before expecting people to believe anything else deduced from it (By the way, I'm not saying dark matter can't exist at all in some minor form, just not as it is taken by the mainstream as a panacea for all their problems).
In contrast to dark matter's arbitrary flexibility, MiHsC is unadjustable. This means that, unlike the dark side, I can't cheat. MiHsC only predicts one possibility, and yet that possibility correctly models the observed anomalies I've tried it on: galaxy rotation, cosmic acceleration, the orbit of Proxima Centauri, the spin of extreme dwarf galaxy Triangulum II, the Pioneer and flyby anomaly, the Tajmar experiments and the emdrive. Meanwhile the mainstream is messing around with the insides of black holes, the early universe and the dinosaurs, confident no-one can disprove them.
But there is hope. In the fifth season of the TV series Happy Days ratings were falling so that the writers wrote in a scene where Fonzie jumped over a shark on skis. Ever since then a useful phrase has entered the English language: to 'Jump the Shark' meaning to use shock tactics to retain dying interest. There's now a similar term 'Nuke the Fridge' based on Indiana Jones 4. The dark matter bandwagon has just jumped the shark, so things may now get interesting.
