Primordial nucleosynthesis helium

It is hard to exaggerate the theological significance of big bang cosmology. Until the twentieth century the Bible was the only “text” explicitly describing the.

In physical cosmology, Big Bang nucleosynthesis (or primordial nucleosynthesis) refers to the production of nuclei other than H-1, the normal, light hydrogen, during. Big Bang nucleosynthesis began a few seconds after the big bang, when the universe had cooled sufficiently to allow deuterium nuclei to survive disruption by high.

Nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons, primarily protons and neutrons. The first nuclei were formed about three. The mass fraction in various isotopes vs time is shown at right. Deuterium peaks around 100 seconds after the Big Bang, and is then rapidly swept up into helium nuclei.

is currently at this stage in its evolution and is fusing hydrogen to create helium . The nuclear fuel (of light elements) which feeds the fusion process eventually.

Hydrogen-Helium Abundance Hydrogen and helium account for nearly all the nuclear matter in today's universe. This is consistent with the standard or "big bang" model.
