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. 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.
