Webb28 juli 2024 · Another set of dark matter theories that many scientists consider to have fallen short is modified Newtonian dynamics (or “MOND”). These theories propose a modification to Newton’s laws of motion that would apply only at very small accelerations, which would adequately explain the abnormal rotation speed of galaxies. Webb15 okt. 2024 · This dark-matter-free model is an extension of the so-called MOND (modified Newtonian dynamics) theory, which assumes that the gravitational force on galaxy scales is different from the standard Newtonian force.
