[QUOTE="snorkack, post: 6435685, member: 436348"] Does a newly created neutrino have a specified mass? Consider a beta decay event. The mother nucleus may have a long half-life. Therefore its momentum can, in principle, be measured with a great precision. The daughter nucleus may be stable, in which case its momentum can be measured with unlimited precision. And electron is stable (ditto). There are certain practical issues with reaching the above Heisenberg precision. But if you followed a number of beta decay events with such precision, what would be your prediction for neutrino rest mass? Same in all beta decay events, or different in different beta decay events of same nucleus, with a continuum distribution? [/QUOTE]
