The author considers the possibility that there is not, in fact, much hidden mass in galaxies and galaxy systems. If a certain modified version of the Newtonian dynamics is used to describe the… Expand

We consider a nonrelativistic potential theory for gravity which differs from the Newtonian theory. The theory is built on the basic assumptions of the modified dynamics, which were shown earlier to… Expand

A new formulation of modified Newtonian dynamics (MOND) as a modified-potential theory of gravity is propounded. In effect, the theory dictates that the MOND potential φ produced by a mass… Expand

A new relativistic formulation of MOND is advanced, involving two metrics as independent degrees of freedom: the MOND metric g{sub {mu}}{sub {nu}}, to which alone matter couples, and an auxiliary… Expand

The modified Newtonian dynamics (MOND) limit is shown to follow from a requirement of spacetime scale invariance of the equations of motion for nonrelativistic, purely gravitational systems, i.e.,… Expand

I pinpoint a previously unrecognized MOND effect that may act in the inner Solar system, and is due to the galactic acceleration gg = ηa 0 : a byproduct of the MOND external-field effect. Predictions… Expand

On considere des spheres isothermes soumises a leur propre gravitation (isotrope et anisotrope) en utilisant une dynamique qui differe de la newtonienne dans la limite des petites accelerations. On… Expand

Prompted by the recent claim, by Donato et al., of a quasi-universal central surface density of galaxy dark matter haloes, I look at what MOND has to say on the subject. MOND, indeed, predicts a… Expand
