Does this mean that there's possibly only one proton?

• kazinator 5y ago
  Two protons P0 and P1 are the same only if they match in every single quantum parameter.

  On the contrary, protons are baryons and they must each have a unique quantum state (they must be in a unique/distinct location).

  You mean like the "One-electron universe" postulate [1]? First, I don't think it's really useful beyond being a fun idea to consider. Also there's a lot more matter than antimatter, which raises some... logistical problems. Also, unlike electrons/positrons, protons are not fundamental particles, they're made up of quarks which throws a whole other wrench in the idea.
