"nothing is real atoms never touch each other youve never touched anything in your life" ok. well when i pet my dog he is soft and when he licks my hand it is wet and that is far more real to me than whatevers going on at an atomic level
what my atoms are doing is their fucking business man i'm busy trying to stop my dog from eating tissues directly out of the box
nuclei don't touch, but the nucleus is not the core of reality. reality is made of electrons dancing. reality is made of bonds.
you pet your dog and the atoms that are you brush up against the atoms that are him, and the electrons that are you press into the electrons that are him, and both of them change their movement.
electrons of course are not really particles and do not really move.
you pet your dog and the electron-orbitals of your skin overlap with the electron-orbitals of his fur, and both are changed by the contact. you are not made of little motes floating alone in a void. you are a single unfathomable chord formed of a trillion vibrations, and so is he. and the note you play is changing at every moment by what you touch and how you breathe, and so is his. and atoms do not really have edges, and to touch is to interact, and when you put your hand on your dog the universe does not know that you are separate. the song expands to hold you both.
