- danbruc 11y agoProtons and neutrons are not considered fundamental because they are made out of quarks and gluons.
- explorer666 11y agoMass is also an emergent property.
- riskable 11y agoTo put it another way: Time cannot exist without mass. Time only exists because everything is always in motion (at least a little bit) and--in our perception--we have a memory/frame of reference. From the perspective of a photon it lives and dies in an instant. Even if it crosses the entire universe!
