Importance of nucleosynthesis in big bang

WitrynaNucleosynthesis is the process of creating new atomic nuclei from preexisting nucleons (protons and neutrons). The primordial nucleons themselves were formed from the quark-gluon plasma of the Big Bang as it cooled below ten million degrees. A few minutes afterward, starting with only protons and neutrons, nuclei up to lithium and beryllium … Witryna1 sty 2024 · Nucleosynthesis is the creation of all the atomic nuclides known to us through a variety of processes that started with an explosive event, the so-called “Big-Bang” and followed by nuclear processes that include fusion, neutron capture, proton capture, energetic particle interactions, and spallation.
