Stacy McGaugh, professor of astronomy at Case Western Reserve, and Mordehai Milgrom, the father of Modified Newtonian Dynamics (MOND) and professor of physics at Weizmann Institute in Israel, say the MOND 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. Modified Newtonian Dynamics (MOND) is an alternative hypothesis to dark matter and succeeded in anticipating the observations. read more
