Feynman diagram

  1. Nov 5, 2012 #1
    Hello all .
    In feynman diagram horizontal direction is space . is that mean distance between particles ?
    is that means two electron must be near a certain distance to create a virtual photon ?

    Does one electron in earth send electromagnetism force to one electron on moon by virtual photon ?
    Does one electron in earth has interaction with one electron on moon by electromagnetism force ?

    Does virtual photons create in short distance ?
    Creation of virtual photon depend on distance between two particles ?

    Feynman diagrams are convenient shorthand for terms in a mathematical expression. They are not meant to be an underlying "billiard ball" mechanics of particle behavior.

    virtual photons are calculational tools,that is why they are called virtual.
