MOND predicts dwarf galaxy feature prior to observations: Also indicates gravity fields vary where dark matter presumes uniformity

MOND, a modified law of gravity, correctly predicted in advance of 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. MOND also detected subtle differences in gravity fields that dark matter theory says should be uniform.
