Sola Nutrino Reality

A nutrino is a basic particle that can't be broken down any further. They generally carry the bits of stuff that have to be conserved in a reaction. If if you have a reaction involving an electron, it will often give off a anti electron nutrino. In the core of the sun, where nuclear reactions are going on, and where hydrogen is getting transformed into helium, nutrinos that should be electron nutrinos are being created.
