Observational tests in scale invariance I: galaxy clusters and rotation of galaxies
Andre Maeder
Galaxy velocities in clusters, rotation curves of galaxies, and "vertical" oscillations in the Milky Way currently show too high velocities with respect to the masses thought to be…

Observational tests in scale invariance II: gravitational lensing
Andre Maeder, Frederic Courbin
We study the path of light rays passing near a massive object, in the context of the scale invariant equation of the geodesics first obtained by Dirac (1973). Using the exterior Sc…
