Big Bang nucleosynthesis and the baryonic content of the universeT X ThuanY Izotov
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...

These messengers from the Big Bang provide a unique window in the early, hot, dense Universe, offering the opportunity for tests of the standard models of particle physics and of cosmology. A new, statistically coherent comparison of the primordial abundances of these nuclides inferred from ...

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 ...
Nucleosynthesis is carried out solely by the mass of quark plasma. All celestial objects were born as quark plasma. The rate at which they create their elements is based on their initial size. That is why black holes are still made of quark plasma and our moon is a mere rock. Reply ...
About three minutes after the Big 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 ...
We study the effects of unstable gravitino on big-bang nucleosynthesis. If the gravitino mass is smaller than 10 TeV, primordial gravitinos produced after inflation are likely to decay after big-bang nucleosynthesis starts, and light-element abundances may be significantly affected by hadro and ph...
