It proposes that a function of unknown form denoted "mu of a over a-zero," which approaches unity if the ratio is much greater than one, alters the law of physics traditionally used to calculate force.
Dodelson and Liguori showed in a 2006 paper that the vector field introduced in Bekenstein's relativistic version of this theory could play a role in generating the instability that produces large-scale cosmic structures. Mathematically, it results from a modification of Poisson's equation, and evidence against this theory came in 2006 when the Bullet Cluster was observed to exhibit gravitational lensing that evidently doesn't result from baryonic matter. It proposes that a function of unknown form denoted "mu of a over a-zero," which approaches unity if the ratio is much greater than one, alters the law of physics traditionally used to calculate force. Proposed by Mordehai Milgrom to solve the problem of galactic rotation, for 10 points, identify this theory that is an alternative to Dark Matter.
