SpletHowever, a dynamic nucleosynthesis calculation taking into account the diffusion of matter, during the nucleosynthesis epoch, between the different density regions produced by the phase transition, has not yet been carried out. We investigate here the consequences of such a diffusion and identify a high-density, {Omega}{sub {ital b}}=1 ...
Nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons (protons and neutrons) and nuclei. According to current theories, the first nuclei were formed a few minutes after the Big Bang, through nuclear reactions in a process called Big Bang nucleosynthesis. After about 20 … Prikaži več Timeline It is thought that the primordial nucleons themselves were formed from the quark–gluon plasma around 13.8 billion years ago during the Big Bang as it cooled below two trillion … Prikaži več Theories of nucleosynthesis are tested by calculating isotope abundances and comparing those results with observed abundances. Isotope abundances are typically calculated from the transition rates between isotopes in a network.
