Mordehai Milgrom.

Mordehai Milgrom (* 1946 in Iași , Romania ) is an Israeli physicist and professor in the Department of Condensed Matter Physics at the Weizmann Institute for Science in Rehovot .

Milgrom studied physics at the Hebrew University of Jerusalem (degree: 1966) and received his doctorate with a dissertation on particle physics in 1972 at the Weizmann Institute. As a postdoctoral fellow at Cornell University , he began to study astrophysics , first high-energy astrophysics and then later on the dynamics of galaxies .

In order to explain the rotation curves of the galaxies, which deviate from the Newtonian and Einsteinian predictions, in 1983 he proposed the Modified Newtonian Dynamics , or MOON for short, of which he is the best-known representative to this day. Often referred to as Milgrom's theory, it is an alternative to the prevailing dark matter explanation.

    "Modified Newtonian dynamics is solely the invention of Mordehai (Moti) Milgrom. The idea of ​​an acceleration-based modification of dynamics or gravity would have probably occurred to someone else sooner or later, but it is safe to say that in the early 1980s no one but Milgrom had considered such a possible modification as an alternative to astrophysical dark matter. It was a brilliant stroke of insight to realize that astronomical systems were not only characterized by large scale but also by low internal accelerations and that this could account for the known systematics in the kinematics and photometry of galactic systems. However, the idea was hardly greeted with overwhelming enthusiasm. "
