t. e. In physical cosmology, Big Bang nucleosynthesis (also known as primordial nucleosynthesis, and abbreviated as BBN) [1] is the production of nuclei other than those of the lightest isotope of hydrogen ( hydrogen-1, 1 H, having a single proton as a nucleus) during the early phases of the universe. This type of nucleosynthesis is thought by Jul 2, 2010 · The big bang theory is an example of enormous, abrupt, and rapid changes at the beginning, so why not assume that there were more similar events in the past?
