I'm not convinced that comparing two different states of matter is a useful comparison. The universe doesn't necessarily work differently, we're just observing different phenomena, aren't we? The behaviour of an atom or subatomic particles in isolation is not necessarily the behaviour of the same particles when part of a much larger system.

Could one could also argue that quantum indeterminacy makes it difficult make predictions the more interactions you add to a system? That is, interactions at the atomic and subatomic levels are manageable enough to observe, but as we add actors, the interactions grow exponentially, and each actor's state is influenced not just by itself but by other actors in the system, ad infinitum.
