Thanks. It is many years since I read Feynman's QED so I need to do some reading.
If they are not constrained by c and have other properties, what is it that defines them as photons rather than 'virtual exchange particles associated with electromagnetic interactions"?
Thank you for your reply.
"Virtual photons don't "really exist" in the same sense that real photons do. They are an artifact of the perturbation-series techniques that we use for calculations in quantum electrodynamics (QED)."
If a diagram were drawn showing an electron interacting with...
So the photons I pick up on my radio receiver aerial are definitely not the same as the exchange particle photons? I wonder why, if they exist, exchange particle photons cannot be intercepted?
No-one on the general board seems to have an answer. I really would like help on this one.
I am told that two static electrical charges exert a force on each other by the exchange of photons.
Nowhere have I read the answers to the following: what are the frequencies/energies of the...
