We see it going the other way neutron > proton-electron-neutrino), but not that way except in our theories and imaginations.And just so we're perfectly clear, "that way" is proton+electron => neutron+neutrino which we do observe in a form of beta decay (I may have been wrong in calling it beta plus - this particular decay is called "inverse beta decay" or "electron capture." But my point stands, protons and electrons combining to create neutrons observed, just as is postulated in the formation of neutron stars.)
Here is your error, if you are able to comprehend it.
