Mediating particles of forces.

  1. May 14, 2015 #1
    We know that there are 4 foundamental forces and that they work thanks to mediating particles:
    Electromagnetic= Photon
    Weak= W & Z Bosons
    Strong= Gluons
    Gravitational= (Graviton)?

    My question is:
    If the electromagnetic field and unlimited range and a particle interacts with another even if they are years light farther in a moment, Doesn't the mediating particle have to be faster than light?
    Same for the not-yet discovered Graviton.

    Its this virtual particle thing - the so called mediating particles don't really exist.

    But - yes - in the mathematical formalism we sum all paths including those travelling FTL.

    But its simply the formalism - they don't really exist.
