That doesn't work because you've left the loop open. If the positron just goes back to 2 and stops, from our point of view it has just appeared from nowhere, which isn't physical.
In order to close the loop you have to go back to 0 and meet the original electron. Once you've done that you lose the asymmetry again.
- V-2 12y agoWell, I won't pretend that I know how it's supposed to work, but even if the loop was closed, the electron (and the loop itself) still must have come to existence out of nowhere somehow, so it doesn't remove this ontological problem :)
- one-more-minute 12y agoI'm not really talking about an ontological problem though, I'm saying that an electron appearing on its own is a physical impossibility. Electrons must appear or disappear alongside a positron partner, which means that the idea of "local asymmetry" can't solve the symmetry problem.
