On: Chaos: The real problem with quantum mechanics

> each time a grain of dust bumps into the moon, this very slightly changes some part of the moon’s wave-function, and afterwards they are both correlated

Help me out here, though. If this is the explanation, then wouldn’t every moon, planet, etc be chaotic, since presumably they all interact with dust and light?

No, the bumps are necessary to produce chaos, but not sufficient.
