    Yes, I see... Thank you!

    Graduate Could electron scatter off vacuum fluctuations?

    Intuitively I understand that. But formally what is a difference between a virtual photon of Coulomb field and a virtual photon of ground state vacuum fluctuations? Why in the first case conservation lows are OK but in the second one not?

    Electron can scatter off virtual photon of Coulomb field (or even emit real photon). But why it cannot do the same off virtual photons of vacuum fluctuations without external field?
