In physical cosmology, Big Bang nucleosynthesis (or primordial nucleosynthesis) refers to the production of nuclei other than H-1, the normal, light hydrogen, during the early phases of the ...

Primordial nucleosynthesis after embryonic inflation, the subject of Chapter 6, yields spatially varying abundances of elements, including heavy elements in all the densest cosmic regions. The theory ...

More importantly, when physicists feed this rate into the equations of Big Bang nucleosynthesis, they predict a primordial matter density and a cosmic expansion rate that closely square with ...

These three elements were – according to the theory – already created early on, through what is known as "primordial nucleosynthesis." ...

According to Big Bang nucleosynthesis (BBN) theory, protons and neutrons combined to form these three elements just a few minutes after the Big Bang. The snag is that while the theory does a good job ...
