No, I’m saying the opposite: the noise comes from the fact that “many
worlds” is nonsense.
our world with very little needing quantum mechanics to be visible.
The Casimir effect measures quantum noise in a <hard> vacuum
caused by virtual particles.
Then there is a noise of amplification, a noise of sampling, a noise
related to the movement of atoms (heat), Brownian motion, and on and on.
All of these noise sources will remain even if the many-world
theory collapses and dies (low probability).
