Conformal Cosmology and Supernova Data

Abstract

We define the cosmological parameters $H_{c,0}$, ${\Omega }_{m,c}$ and ${\Omega }_{\Lambda ,c}$ within the Conformal Cosmology as obtained by the homogeneous approximation to the conformal-invariant generalization of Einstein's General Relativity theory. We present the definitions of the age of the universe and of the luminosity distance in the context of this approach. A possible explanation of the recent data from distant supernovae Ia without a cosmological constant is presented.
