Force carrying particles

  1. Feb 18, 2006 #1
    one simple but complicated question me is roaming in my mind since many days.We know about force carrying particles i.e gravitons,etc this particles carry force. but this particles are mass less and virtual then how can they carry force or energy???

    Photons are massless and virtual, but they do the trick.

    it is hard to visualize these things. all these are part of theoritical models to decribe experimental observations. as long as they fit the model and we are able to explain the experimental observations, no body cares. u just have to beleive it for a while, until u study things in deep. but these are very concrete ideas now.
