If you tap on a desk, or are walking, does that energy that is being transferred cause electrons in the desk or ground to jump oribitals and emit infrared light? Also, I've read that electrons never touch each other, and that there is actually some space between you and everything that you think you touch. So you never actually touch any of the food you eat, or anyone you kiss, or even the floor that you're walking on. Is the relationship between electrons kind of like the relationship between magnets with opposite poles facing each other? Where the electron particle is like the magnet itself, and the electron's field is the like the magnet's field? So the electron particle itself doesn't actually touch any other electron particle, but both of their electromagnetic fields do, just like magnets don't touch each other sometimes but there magnetic fields do? So you don't actually touch anyone elses or anything elses electrons, but you do touch there electromagnetic fields with yours?
