Elementary particles, including electrons and quarks, are classified as zero-dimensional point particles, meaning they possess no size. This classification raises questions about the nature of these particles, particularly whether they could have a size that is simply too small to detect. Current physical models assert that if these particles had a non-zero diameter, it would contradict established physics by introducing a finite duration for signals to traverse their dimensions.

Can't point particles have size that is just too small to see?ajv said:All elementary particles, which are not made up by any other particles (electrons, quarks), are said to be zero dimensional and have no size. But why not? Are electrons literally zero dimensional particles with no size?
