摘要
Big-Bang nucleosynthesis （BBN） offers the deepest reliable probe of the early Universe, being based on well-understood Standard Model physics [1]. Predictions of the abundances of the light elements, D, 3He, 4He, and 7Li, synthesized at the end of the ＇first three minutes＇, are in good overall agreement with the primordial abundances inferred from observational data, thus validating the standard hot Big-Bang cosmology （see [2-5] for reviews）.
