===About Neutrinos===

: '''Neutrinos''' are very difficult to detect but they have been demonstrated to exist due to the law of [[Conservation of Momentum|conservation of momentum]] applied during [[Radioactive Decay|decay]] occurring due to the [[Weak Nuclear Interaction|weak interaction]]. During a [[Radioactive Decay|decay]] the observable products can be seen to move in such a way as would violate [[Conservation of Momentum|conservation of momentum]] showing that another [[Subatomic Particle|subatomic particle]] must be created in the [[Radioactive Decay|decay]].

: Due to their negligible [[mass]], [[neutrino]]s are very stable and pass through most [[matter]] without any interaction.
