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
jhmar said:Particles without any apparent internal structure. Quarks, electrons, etc
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
Fundamental particles are the basic building blocks of matter. They are the smallest, indivisible units that make up all matter in the universe.
Currently, there are 17 known fundamental particles in the Standard Model of particle physics. These include 6 quarks, 6 leptons, and 5 bosons.
Yes, all fundamental particles are singular. This means that they cannot be divided into smaller units and they exist as individual particles.
Yes, fundamental particles can combine to form larger particles. For example, quarks combine to form protons and neutrons, while protons and neutrons combine to form atoms.
Scientists have conducted numerous experiments and observations that demonstrate the indivisibility of fundamental particles. Additionally, the Standard Model of particle physics, which has been extensively tested and verified, also supports the idea of singular fundamental particles.
