Virtual particles in Feynman diagrams

Click For Summary
SUMMARY

The discussion focuses on the interpretation of Feynman diagrams, specifically the transformation of photons into electron-positron pairs and the emission and reabsorption of photons by electrons. The first diagram illustrates a photon converting into an electron-positron pair and reverting back to a photon. The second diagram raises questions about whether an electron is being converted into an electron-photon pair, emphasizing the complexities of visualizing particle interactions in quantum field theory.

In the first diagram above, if I understand it correctly, the photon turns into an electron positron pair and then back again to a photon. However, what exactly is happening in the second diagram at the bottom left hand corner? Is the electron being converted to an electron photon pair?

To the extent that a Feynman diagram shows something "happening" (which is to say, not much at all) the electron is emitting and then reabsorbing a photon.
