A framework for the next generation of stationary cosmological models

Abstract

According to a generic tired-light hypothesis found consistent with H(z) data, the density number of galaxies has been nearly constant over the last 10 Gyr at least, the density number of star-forming galaxies, as probed by sources of gamma-ray bursts, being constant as well, meaning that, as far as galaxies are concerned, the Universe has been stationary. On the other hand, an analysis of the luminosity distances of quasars and supernovae Ia shows that the Universe is far from being as transparent as assumed nowadays, the photon lifetime along the line-of-sight being one third of the Hubble time.
