## Main Question or Discussion Point

hi

i heard some things about quantum electrodynamics and one thing was that they gave up the concept of actual fields and said that the electromagnetic information from one particle to the other is transported by photons.

Now my question is: Can one observe these photons or is it just a mathematical concept?
