This is known as the ‘epoch of recombination’. 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.
