I'm pretty sure electrons are not considered point particles?
- qubex 6y agoPretty sure they are. They’re leptons, and elemental (within the confines of the Standard Model, at least).
- centimeter 6y agoSomething being a lepton has nothing to do with whether it's a point particle. Pontryagin duality of position/momentum (which comes from both QM and Relativity, depending on your perspective) rules out the physical existence of point particles. It would require infinite momentum to have zero extent.
