As @AccidentalFourierTransform points out in their answer, position on a Feynman diagram does not represent position or time. The graph connections are what matter - not the locations of the nodes. | |

| Dec 6, 2016 at 17:39 | comment | added | user56963 | I mean consider an external leg in the Feynman diagram. Are both momentum and position exactly measured? | |
