Why Can't We Walk through Walls?
Alice wonders why Alice can’t walk through a wall if atoms consist mostly of empty space. Bob suggests that it may be because like charges repel, but then if atoms are neutral then there would be no net charge. Alice and Bob come the conclusion that they need quantum theory to explain why solids can’t pass through one another.
