- How are forces “mediated”? 5 answers
Say, there are 2 stationary electrons placed at a distance. The result of observation would be both flying apart with the same speed and the opposite direction, which would obey laws of conservation of momentum and energy (as electric potential energy is converted into kinetic energy). But if considered from the perspective of emitting and receiving photons, how is the process like? Where does the energy come from? Does the mass of either electron change? Or should I not try to understand it from the classic point of view?
