Newtonian equation for gravity
Witryna3.1 Modified gravity. Modified gravity is also known as “modified Newtonian dynamics”. The motivation behind this hypothesis was to explain the observed “rotation curves”, i.e., why the stars in most galaxies are observed to move at similar speeds regardless of their distance from the center of the galaxy.
