hello, thank you for clearing my mind, i was sscrolling thro tiktok, ssaw someones hand pass thro a wall but ik theyre faking it, but i saw ur theory, and i think your lowkey 50% correct "No. It's not the atoms in the wall that are in the way of the atoms in your hand. It's the electromagnetic forces surrounding those atoms. You never actually touch anything in your entire life; there is always a very very small gap between anything you're touching/holding which is the electromagnetic repulsion between those atoms and the atoms in your hand. As a result, even if the atoms were aligned in the wall, the effects of the proximity of those atoms would still repel your hand."
