Some excellent results for the modification of Newton's simple assumptions on gravity have been achieved just recently: MOND predicts dwarf galaxy feature prior to observations: Also indicates gravity fields vary where dark matter presumes uniformity
I would like to make the speculation that dwarf galaxies nearer the host, Andromeda, are also closer to it's plane of rotation. Isn't it quite possible that there is an additional force of attraction on the plane of rotation of a galaxy which would explain these results? It would also have imminent potential for explaining the spiral galaxy rotation curve enigma. Aren't the best ideas often the simplest?
CLEVELAND —A modified law of gravity correctly predicted, in advance of the observations, the velocity dispersion—the average speed of stars within a galaxy relative to each other—in 10 dwarf satellite galaxies of the Milky Way’s giant neighbor Andromeda.
The relatively large velocity dispersions observed in these types of dwarf galaxies is usually attributed to dark matter. Yet predictions made using the alternative hypothesis Modified Newtonian Dynamics (MOND) succeeded in anticipating the observations.

The paper’s calculations using MOND also reveal subtle differences in the gravity fields of dwarfs near and far from the host galaxy Andromeda. The gravity fields of dwarfs far from the host appear to be dominated by stars within the dwarf, while the gravity fields of dwarfs close to the host appear to be dominated by the host. No such distinction is expected with dark matter.
