### modified Newtonian dynamics

**(MOND)**
(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 motivates the concept of dark matter.
It outlines a pattern in the force of gravity in which
the force is weaker at longer distances.
It is not widely accepted in astrophysics, but writeups of
astrophysical experiments or observations which have the potential
to provide evidence for it, show consistency with it, or contradict
it do sometimes mention that.

**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.
