Yes. This is why Physicists will reject the "everything is a wave theory" till the bitter end. They become frustrated when faced with the un-measurable.

There is no "quantum wave", there are only waves. Immeasurable, undefinable waves.

Earlier you wrote, "Everything is a quantum wave." You also linked to an article titled, "The Everything-Is-a-Quantum-Wave Interpretation of Quantum Physics."

You seem to be contradicting yourself.
