Is there any current theory for the following oddities? 1. Quarks come in pairs (up,down). (charm,strange), (top,bottom). The up and down are approximately the same size (mass). However, the charm is much heavier than the strange and the top is much heavier than the bottom. How come? 2. The only stable baryons (under normal conditions) are those made up of up and down quarks. The only stable charged lepton is the electron. However, in the case of neutrinos, they all seem to morph into each other. How come?
