41 17 v 3 1 J an 2 00 8 Weyl-Dirac theory predictions on galactic scales

Abstract

We consider the Weyl-Dirac theory within the framework of the weak field approximation and show that the resulting gravitational potential differs from that of Newtonian by a repulsive correction term increasing with distance. The scale of the correction term appears to be determined by the time variation rate of the gravitational coupling. It is shown that… (More)
