>>11538254i used to have a peer back in undergrad physics who i swear was just learning physics to try to find flaws in well established theories
he would say "how can you be sure if a particle is an electron, it could just be behaving like an electron in certain cases"
i told him "if it walks like an electron, and quacks like an electron, it's safe to assume it's an electron unless you can demonstrate otherwise"
i don't think he ever graduated
