Universal wave function, 14

Quantum decoherence makes the macroscopic world appear definite.

In fact, Nature is fundamentally a superposition of definite states.

So the world, either microscopic or macroscopic, is definite in a sense that the universal wave function is evolving deterministically; and

is indefinite in a sense that it is not in a particular eigenstate.
