The Hubble Tension in Light of the Symmetry of Scale Invariance
Frederic Courbin, Andre Maeder
When the expansion rate of the Universe at recombination is used to infer the present expansion rate , the value derived in the CDM model, km/s/mpc, is about in…

A Survey of Dynamical and Gravitational Lensing Tests in Scale Invariance: The Fall of Dark Matter?
Andre Maeder, Frederic Courbin
We first briefly review the adventure of scale invariance in physics, from Galileo Galilei, Weyl, Einstein, and Feynman to the revival by Dirac (1973) and Canuto et al. (1977). We…
