Abstract
We present exact solutions to the conformal Weyl gravity cosmological equations valid for both the matter-and radiation-dominated eras. We s how that the cosmological models derived from this theory are not like ly to reproduce the observational properties of our universe. They fai l to fulfill simultaneously the observational constraints on present c osmological parameters and on primordial light element abundances.
