When an electron moves from one orbital to another, it basically teleports because it can’t exist between orbitals. But if that happens instantaneously, it would effectively travel faster than light over that small distance–infinitely fast, in fact. Does the electron reappear some time later as constrained by the speed of light? If so, where is the electron in the meantime, since it can’t be between orbitals? If not, how is it allowed to travel faster than light?
