At the level of individual atoms, the universe behaves extremely strangely as described by quantum mechanics. When atoms are clumped together by the trillions in ordinary objects, these effects are averaged out and washed out and things behave normally. Our intuition expects the atomic level to behave the same as it does on the level of soccer balls, but that is merely because we have no experience watching individual atoms.
