A tactical guide to the infinite realm of science. Although the world of science would take eternity to explore, Professor Quibb attempts to scrape the edge of this Universe. This blog helps you to understand particular topics under the more general categories: cosmology, mathematics, quantum physics, meteorology and others. Join me on my trek across the untraversed lands of the unknown.

Big Bang Nucleosynthesis
This stage of the Universe lasted 17 minutes from 3 to 20 minutes after the Big Bang. It occurred over the entire Universe. The process started one second after the Big Bang when the temperature and density dropped enough to support stable protons and neutrons. The temperature stayed high for nuclear fusion only enough time for atom nuclei (note 2) lighter than Beryllium to form. After this period was over no more atoms fused until stellar formation This material was the beginning of the formation of stars and galaxies millions of years later.
