Cosmic birth rite

Research output: Contribution to journalReview article

Abstract

Various possibilities for testing different theories on the formation of ordinary matter are discussed. The proportions of other light elements, which were not burnt to helium-4 by the time cosmic fusion ceased, are focused to test the theory of big bang nucleosynthesis (BBN). The cosmic microwave background radiation (CMB) is a probe for the atomic age, when electrons and nuclei condensed into atoms. The spectrum of the microwaves at different positions in the sky measures the cosmic temperatures and this is a probe of densities of matter.
