In physics, modified Newtonian dynamics (MOND) is a theory that proposes a modification of Newton's laws to account for observed properties of galaxies.
The theory's original motivation was to explain that the velocities of stars in galaxies were observed to be larger than expected based on Newtonian mechanics.
