Resumo

Physics, as known from our local, around—earth experience, meets some of its
applicability limits at the time just preceding the period of primeval nucleosynthesis. Attention
is focussed here on the effects of the nucleon size. Radiation—belonging nucleons are
found to produce an extremely high pressure at kT ≈ some tens or hundreds of MeV. Quark
deconfinement at higher energies would not change the results.
