I think there's close to 1e100 photons per atom, and that's a lot of photons to work with. ~ BG

Then using E=mc2 you can calculate a mass equivalent value for each photon. The photons which we perceive as light are the photons exchanged between electrons. Photons associated with the nucleus are higher frequency/energy than light. If we divide the known and measured mass of the electron by the average mass equivalent value of photons associated with them, we can get the number of photons it would take to make up an electron. Einstein believed that mass was transferred between objects with each photon that was exchanged. Double-A |
