I've suggested (& published in 21 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.

QI & MoND vs the data: new figure.


Someone helpfully suggested that I should redo the Figure that I published in this paper (in Astrophysics and Space Science) using a vertical log scale, and the result is much clearer and is shown below. This Figure shows the baryonic mass of the astronomical system in Solar masses along the x axis, from the light dwarf galaxies, through gas discs and spiral galaxies and up to galaxy clusters. The vertical log axis shows the rotation speed of the system in km/s. The black circles are the observations (from McGaugh et al., 2010).



















MoND predicts the two dotted lines, but to do this you must "tune" its adjustable parameter (a0) by hand to be 1.2x10^-10 m/s^2 or 2x10^-10 m/s^2. Quantised inertia (MiHsC) predicts the dashed line without any adjustable parameters. See here or the preprint for more details. So both MoND and MiHsC agree with the data within its uncertainty but MoND has to be "tuned" to fit, whereas MiHsC works as it is.
