Bang, the first nuclei were formed through a process called Big Bang Nucleosynthesis. At that time hydrogen and helium were formed and became the building blocks of the first stars. This process is also responsible for the hydrogen/helium ratio of the cosmos, which is observed today [1]...
Big-bang nucleosynthesisCHAMPspallation processWe propose helium-4 spallation processes induced by long-lived stau in supersymmetric standard models, and investigate an impact of the processes on light elements abundances. We show that, as long as the phase space of helium-4 spallation processes is ...
The nucleosynthetic process that took place within the first 20 min after the Big Bang is called Big Bang Nucleosynthesis (BBN) or Primordial Nucleosynthesis. At this early epoch, the Universe was dense and hot enough to allow for nuclear reactions to take place, producing the “light elements...
Big Bang Nucleosynthesis refers to the era in the early universe when nucleons combined to form light nuclei, such as deuterium, helium, and lithium, as the primordial plasma cooled down. This process depended on the rates of electromagnetic, weak, and strong interactions, as well as the expan...
* Big bang nucleosynthesis has given no account of the universe: Although claimed as one of the major confirmed predictions of the big bang theory, the "predicted" initial abundances of elements allegedly made in the big bang account for only a tiny percentage of all the "stuff" that should...
The current state of affairs in big-bang nucleosynthesis is reviewed and controversies are discussed. The author concludes that the glass is half full.Turner, M Sdoi:10.1111/j.1749-6632.1984.tb23345.xMICHAEL S. TURNERAstronomy and Astrophysics Center Enrico Fermi Institute The University of ...
