Widdekind Posted May 31, 2011 Posted May 31, 2011 According to this site, given the observed abundances of Deuterium, 3-Helium, & Lithium, Primeval Nucleosynthesis could have occurred, at almost any temperature, T < 500 MK, with next-to-no discriminative sensitivity beyond that. What is the cosmic abundance of neutrons (which would discriminate) ??
swansont Posted May 31, 2011 Posted May 31, 2011 I don't see where the website makes that claim. That's not what the graph is telling you.
