In the standard picture of big-bang nucleosynthesis the yields of D, 3He, 4He, and 7Li only agree with their inferred primordial abundances provided the fraction of critical density contributed by baryons is between 1% and 15%. If the \ensuremathτ neutrino has a mass between 20 MeV and 30 MeV and a lifetime between 200 sec and 3000 sec and its decay products include electron neutrinos this crucial bound is relaxed by a factor of 10. Experiments at e^\ifmmode±\else\textpm\fi colliders should soon test this possibility.
