A Case of MOND Over Dark Matter

Source: Universe Today

According to Newton's Second Law of Dynamics, objects on the farthest edges of galaxies should have lower velocities than objects near the center. But observations confirm that galaxies rotate with a uniform velocity. Some astronomers believe the orbital behavior of galaxies can be explained more accurately with Modified Newtonian Dynamics (MOND) — a modified version of Newton's Second Law — than by the rival, but more widely accepted, theory of dark matter.
