A detailed explanation (for the lay man) of this process is available in this article about [http://www.irregularwebcomic.net/3280.html Making Atoms]. |
From this article (and from the wiki article on Big Bang) it is clear that our universe began not only with hydrogen. Although the majority of atoms produced by the Big Bang were hydrogen, lots of {{w|helium}} and traces of {{w|lithium}} were also produced. Actually {{w|Big Bang#Abundance of primordial elements|about 25%}} of the non-dark mass in the universe comes from helium created shortly after the Big Bang. (See also the later comic [[2723: Outdated Periodic Table]] about which atoms were around after the Big Bang). | From this article (and from the wiki article on Big Bang) it is clear that our universe began not only with hydrogen.
