Does virtual photons exist?
« on: 22/09/2012 20:08:49 »
Hey,
red in a book (forgot which one) that they exist, that they can even be measured in giving an electron slightly more energy than i has by it self.
Now reading "the theory about almost everything", and they mean that the virtual photon is a "handy concept" but apart from this no one knows
if they exist....

Can anybody enlighten me?

Thanks Magnus

They are not real, but everything goes "as if" they existed. Essentially they are a useful mathematical instrument, but nothing else than this, infact the same problem could be solved without making use of them and gives the same results.
