Universal wave function, 9

Uncertainty principle, 4
The uncertainty principle is due to the phenomenon of wave function collapse. No collapse, no uncertainty.

The universal wave function does not collapse.

However, since the “final result” is a superposition of eigenstates, we can re-define the uncertainty in terms of the eigenvalues and their probability weightings.

The last sentence tries to answer

Is the uncertainty principle still meaningful if there are never wave function collapses?


What is the meaning of “uncertainty” if the universal wave function just evolves unitarily and deterministically?
