Abstract
We show that the observed zenith angle dependence of the atmospheric neutrinos can be accounted for by neutrino decay. Furthermore, it is possible to account for all neutrino anomalies with just three flavors. A decay model for Majorana neutrinos appears consistent with big-bang nucleosynthesis and supernova constraints. The decay model is testable in the near future.Keywords
