I've suggested (& published in 15 journal papers) a new theory called quantised inertia (or MiHsC) that assumes that inertia is caused by relativistic horizons damping quantum fields. It predicts galaxy rotation, cosmic acceleration & the emdrive without any dark stuff or adjustment.

Quantised inertia on galactic scales

I'm pleased that my paper (Testing quantised inertia on galactic scales) has just been accepted by the journal Astrophysics and Space Science. I used the data published by McGaugh, Schombert, de Blok and Zagursky (2006) listing the baryonic mass and circular velocity of dwarf galaxies, spiral galaxies and galaxy clusters. In the paper I show that MiHsC (quantised inertia) predicts the observed circular velocity of all these structures (within the uncertainties) from their baryonic mass only (ie: without dark matter).

In more detail: MiHsC overestimates the circular velocity of galaxies (but still agrees within the error bars) whereas MOND agrees better with galaxies, if you set its adustable parameter (a0) correctly. On the other hand MiHsC agrees better with large galaxy clusters, where MoND has always had trouble, and a very important advantage of MiHsC is that it doesn't have any adjustable parameters. The paper is on the arxiv here.
