The nuclei formed in big bang nucleosynthesis had to wait a long time before they could team up with electrons to make neutral atoms.... WitrynaOver the last two decades big-bang nucleosynthesis (BBN) has emerged as one of the cornerstones of the big bang, joining the Hubble expansion and the cosmic microwave background radiation (CBR) in this role. Of the three, big-bang nucleosynthesis probes the Universe to the earliest times, from a fraction of a second to hun-dreds of seconds.
