Scientific paper

There are three observational facts which strongly support the hot Big-Bang cosmology: the universal Hubble expansion, the existence of the cosmic microwave background, and the agreement between the predictions of the primordial nucleosynthesis theories and the observed abundance of light elements. Based upon the Friedmann-Robertson-Walker homogeneous and isotropic models, it accounts for the evolution of the universe from 10-2s to ≡1010y after the bang. The author wants here to discuss how these observations can be used to constrain the theoretical model.
