What is the central premise of Modified Newtonian Dynamics (MOND) regarding galactic rotation?

MOND suggests altering the relationship between acceleration and force at very low acceleration values.

Modified Newtonian Dynamics (MOND) represents a theoretical approach to solving the galactic rotation problem that does not invoke the existence of new, undetected particles like dark matter. Instead, MOND suggests that the fundamental laws governing gravity, specifically the relationship between force and acceleration derived from Newtonian mechanics, must be adjusted or modified when dealing with the extremely low acceleration regimes characteristic of the outer edges of galaxies. By changing how acceleration responds to gravitational force at these low thresholds, MOND can mathematically mimic the effect of additional gravitational mass required to flatten the rotation curves, effectively accounting for the observed dynamics without requiring the creation of massive, unseen components.
