Hello all. Firstly, know that I need a little handholding. We are told that in the detail, the actual behavior of matter is better modeled with quantum theory concepts, apparently to a impressively proven accuracy, even if the mathematical aids involve counterintuitive, though useful, notions. Even so, I do expect the concepts to model everything, even large scale slow moving lumps at huge distances. I am happy to reach for Mr. Newton's handy handbook if the Quantum Theory effects become small enough to ignore. Hence my first Feynman diagram. An electron approaches another, and they repel because as they get close, a photon passes between them with enough energy to give it momentum in a new direction. Here The little photon, shoving off from one electron, changes its direction, and then hits the other electron, and sends it aside also. I know I can launch a couple of charged balloons together, and they repel. I can hang them up from a single hook in the ceiling, and they stand apart for hours. I do not notice any photons passing between them, even if I start shoving them about. Is there really any radiation passing between them at some frequency hard to observe? Does it actually happen? I observe electronic forces repulsion in large masses (balloons) at huge distances (many centimetres) from billions of these together, presumably furiously repelling each other (and exchanging photons) on the same balloon. But the other balloon is a bit further away! How is this scenario represented in using Quantum concepts?
