If I know that I'm moving at the same velocity as you, that means that I know your velocity with respect to me is 0m/s exactly, and hence your momentum with respect to me is 0kgm/s exactly. So your momentum uncertainty is 0, which means your position uncertainty is infinite. | |

Can you please elaborate on this: "You can't know you're in a comoving frame and know the electron's position at the same time. If you can be sure you're in a comoving frame, then you know the electron's momentum exactly"? You mean that in a co-moving frame, we know the momentum, but not the position? Why? I would have thought the other way around. | |
