Do subatomic particles have solid surfaces?

No. Subatomic particles are not like anything you experience in the classical world. In particular, they are not miniature cannonballs or planets or whatever. In a quantum particle theory, elementary particles are point-like. read more

No, subatomic particles do not have solid surfaces. Physicists describe these particles as point like particles that are associated with energy fields. The problem is that physicists have no clue as to how a point becomes associated with an energy field. read more

Based on the known sizes of subatomic particles, however, the surfaces of charged particles would have to be moving faster than the speed of light in order to produce the measured magnetic moments. Furthermore, spin is quantized, meaning that only certain discrete spins are allowed. read more
