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 universe, shortly after the big bang.
Up to this time (just over three minutes past the beginning) there had been no nucleosynthesis this was a result of the high energy density. Nucleosynthesis definition is - the production of a chemical element from simpler nuclei (as of hydrogen) especially in a star the production of a chemical element.

Nucleosynthesis: the universe is now 1 minute old, and all the anti-matter has been destroyed by annihilation with matter the leftover matter is in the form of electrons, protons and neutrons. Stellar nucleosynthesis refers to the synthesis of heavy element nuclei due to nuclear fusion reactions taking place within a star there are several types including the explosive or supernova nucleosynthesis, the big bang nucleosynthesis and the cosmic ray spallation.Nucleosynthesisの意味や使い方 核合成 元素合成 原子核合成 元素形成 - 約1079万語ある英和辞典・和英辞典。発音・イディオムも分かる英語辞書.

High quality content by wikipedia articles supernova nucleosynthesis is the production of new chemical elements inside supernovae it occurs primarily due to explosive nucleosynthesis during explosive oxygen burning and silicon burning.
Nucleosynthesis definition: the formation of heavier chemical elements from the nuclei of hydrogen or other lighter elements, as in the interior of a starorigin of. Nucleosynthesis is the process of creating new atomic nuclei from preexisting nucleons (protons and neutrons) the primordial preexisting nucleons were formed from the quark-gluon plasma of the big bang as it cooled below ten million degrees.
