Virtual particles in interactions

  1. Mar 2, 2012 #1

    so we have just started doing some physics of fundamental particles etc at school.

    i am reading alot about the exchange of 'virtual' photons etc. i am confused about whether these particles actually exist in a physical sense or whether they just have to be there to conserve quantities?

    i know that is quite vague, but what is actually meant by a virtual particle?

    thanks in advance for any light you can shed.
