We recently showed that the energy density of a plasma is appreciably different than previously thought when high frequency plasma fluctuations, ω ≥ kB/ħ, are taken into account (M. Opher &R. Opher, 1999). A change in the primordial plasma energy density changes the primordial expansion rate of the universe, the neutron temperature freeze-out, and the primordial nucleosythesis abundances. The change in the primordial abundances due to the change in the primordial plasma energy density is evaluated, taking into account the high frequency, as well as the low frequency fluctuations of the plasma.
