modified Newtonian dynamics

(alternative theory of gravity addressing "dark matter")

Modified Newtonian dynamics (MOND) is a theory of gravity developed in 1983 by Mordehai Milgrom, offering an explanation for the same dynamics that dark matter explains. It is not widely accepted in astrophysics.

Entropic gravity (or emergent gravity) is a 2007 theory developed by Erik Verlinde that bases a MOND-like gravity on string theory and hypothesizes a relation between gravity to entropy. It results in divergence from the usual gravitational formula at extremely small distances.
