Dark matter: Our review suggests it's time to ditch it in favor of a new theory of gravity

[Admin]

Observations across a vast range of scales are much better explained in an alternative theory of gravity requiring no invisible matter.

The basic premise of MOND is that while Newton's laws have been extensively tested in high-acceleration environments (in the Solar System and on Earth), they have not been verified for objects with extremely low acceleration, such as stars in the outer parts of galaxies. This led Milgrom to postulate a new effective gravitational force law (sometimes referred to as "Milgrom's law") that relates the true acceleration of an object to the acceleration that would be predicted for it on the basis of Newtonian mechanics
