WebMay 30, 2024 · Stellar nucleosynthesis is the process by which elements are created within stars by combining the protons and neutrons together from the nuclei of lighter elements. All of the atoms in the universe began as hydrogen. Fusion inside stars transforms hydrogen into helium, heat, and radiation. WebSep 15, 2024 · Since some of the inhomogeneities generated in the electroweak epoch have an amplitude of only 10^4, these will decay and have no effect on the quark hadron phase transition or the nucleosynthesis epoch. We also study the decay of the inhomogeneities after the quark hadron phase transition.

We present numerical calculations regarding the nucleosynthesis epoch and calculate the light and heavier element abundances in both ordinary and mirror worlds as a function of x=T'/T.

WebJan 6, 1998 · This yields a time scale for the epoch of nucleosynthesis of T = 1.75 ± 0.25 Gyr and a limiting age for the Galaxy (T + τ SS) of. (T + τSS) = 6.3 ± 0.25Gyr. We can similarly use the 232 Th/ 238 U ratio to arrive at a lower bound on the galactic age. For the case of the 232 Th/ 238 U pair, the appropriate equation is. WebThe earliest epoch in the hot Universe which has been tested observationally is the Big Bang Nucleosynthesis epoch (BBN).
