On the cosmological implications of the Calogero conjecture

We discuss the implications of the Calogero hypothesis on the "cosmic origi n of quantization",(1) and of the variation of h with time it implies, for cosmology. We focus on two issues: (a) how the relation between redshift an d distance would be modified; and (b) how the observations on the cosmic ba ckground radiation, and the estimation they give of the time elapsed since its production, would be interpreted in the light of Calogero hypothesis. W e also check that the hypothesis is compatible with the present bounds on t he variations of fundamental constants and with the observed black body dis tribution of the cosmic background radiation.
