Neutrinos of different “flavor” quantum states (shown by colors) are entangled through interactions. In dense neutrino environments like core-collapse supernovae, this leads neutrinos of different flavors to equilibrate to similar energy distributions.

Understanding of the proton has changed from the 1980s view of the proton as made of three valence quarks (left) to the modern view that it is made of valence quarks, sea quarks, and gluons rotating in different directions around its spin axis (right).
