The asymmetry of the universe between matter and antimatter in the universe is related to neutrino properties due to non‐perturbative processes in the high‐temperature symmetric phase of the standard model. We show that the neutrino masses inferred from the solar and atmospheric neutrino anomalies are consistent with the hypothesis that the observed cosmological matter density has been created in decays of heavy Majorana neutrinos in the early universe.
