When you touch something there isn't really any "physical" contact When you touch something there isn't really any "physical" contact, it's just the electromagnetic forces that repel each other. So if I try to touch a table, no particles from my hand actually touches any particles from the table, right? So if we imagine my fingers where made of particles without any charge and I was trying to pick up a brick made out of particles without any charge with my fingers, then what would happen? Would I be able to touch the brick? If not, what would it look like if I tried? If yes, what would that look like? (A more realistic example could be 2 neutron stars colliding.) And second, can you see a hand made out of particles with no charge? Regards.
