'''Nucleosynthesis''' is the process of creating atomic nuclei fro pre-existing [[proton]]s and [[neutron]]s. According to standard cosmological theories, a few minutes after the [[Big Bang]] most of the hydrogen in the universe was formed, as well as small quantities of helium and beryllium. Heavier elements are formed mainly inside [[star]]s, through the process of [[nuclear fusion]].
