electrons are singularities if you don't believe so you are a schizo. they are points in space with mass thus have infinite density.
>but muh QFT they arent points blah blah blah
field collapses in certain circumstances such as a collision and become points in space. thus are singularities at least in that circumstance.
>but science is wrong blah blah
dont care in our models they are points so they are points. If you dont think so you are a brainlet.
