Answer 1

what you call “touching” (or “bumping against a solid object, hurting yourself”) is actually the electric field of the molecules in your body interacting with the electric field of the object you’re close to.

think of it like a bunch of magnets, except that the ramp up much faster and at a much shorter distance.
