Is there a fundamental particle (like a Planck black hole) that has a finite radius?
I'm not exactly sure what you mean by a fundamental particle

This the QT view, particle physics give figures for the electron radius and atomic nuclei radii. Therefore they must have internal structure, its the old take your choice atitude.

kublai said:QT treats particles as wavy perturbations in a field of said particles, therefore no finite bounds, think fuzzy. Since QT is a nondeterministic, probablistic theory it could not allow for discrete, finite particles. The days are gone where particles were little round, hard balls. sigh
