At the subatomic level, what we feel as touch is actually electromagnetic repulsion.Atoms are surrounded by negatively charged electrons, and when you bring your hand close to an object, the electrons repel each other. This prevents true contact, leaving a tiny gap between atoms.In quantum mechanics, particles are described by probabilities, so there is an extremely small chance they could pass through barriers via quantum tunneling.If nuclei were pushed close enough to overcome the Coulomb barr
