What does "touch" look like in the subatomic world? From my understanding, what looks like touch for us (e.g. my hand pressed against a wall) is not actually "touch," but a sensation. The charged particles in my hand are not actually "touching" the inversely charged particles in the wall, but are instead repelled by them, and it is this repulsion that gives me the sensation (and appearance) of touching. However, is there a phenomenon of actual "touching" for subatomic phenomena? If so, what would this look like? Do we have a picture for it?
