Non Newtonian Dynamics in Galaxies and Satellite Galaxies

Abstract

Recent studies have thrown up a big enigma. On the one hand they point to satellite galaxies rotating faster than they should with the usual theory. On the other hand they also go against explanation of Newtonian gravity with dark matter. In this brief note it is argued that the varying $G$ cosmology which explains all the observed General Relativistic effects and the Pioneer anomaly reconciles the controversial conclusions of the latest observations.
