The Hyades star cluster has a strange distribution of stars that could be explained by an alternative theory of gravity NASA, ESA, and STScI
A strange effect in clusters of stars is bringing our ideas of how gravity works into question. These star clusters seem to have an unexpected asymmetry, which fits better under an alternate theory of gravity called modified Newtonian dynamics (MOND) than under Albert Einstein’s widely accepted theories.
Clusters of stars typically look a bit like a two-armed pinwheel with opposing tails, each formed when stars bouncing around within the cluster …
