Time is an emergent property. Ie: fundamental particles don't experience time, but things made of them do.

- imaginenore 11y agoEverything that has mass, must experience time. That includes electrons, protons, neutrons, which are considered fundamental.
- 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!
- danbruc 11y agoThat is not true, (fundamental) particles experience time (except massless particles moving at the speed of light). Best example are neutrinos which are, as far as we can tell, fundamental and undergo neutrino oscillations nonetheless.
- Ono-Sendai 11y agoAlso electrons experience time, in the sense that they will jiggle around over time.
