Q_1_17 — Modified Gravity Theories (MOND, TeVeS, and Alternatives to Dark Matter)

Modified Newtonian Dynamics (MOND) is a hypothesis proposed by Mordehai Milgrom in 1983 that modifies Newton's second law at very low accelerations (below approximately 1.2 × 10⁻¹⁰ m/s²) to explain galaxy rotation curves
