I was on another forum and somebody was talking about quantum tunneling and that walking through walls was not impossible. Just highly improbable; the probability of it happening is older than the universe. Some reason it blew my mind away, even though not much was said. Anyone have more insight or thoughts on this subject? Does this mean it could be possible some building has phased through into the ground over these years? Or if my keyboard suddenly falls through my desk, I shouldn't be afraid of some supernatural cause but go hey, quantum tunneling.
