Quantum Quote by Andrew Thomas
““So in the MWI, the problematic quantum jump is just transferred from the object under observation to the measurement apparatus. The MWI shuffles the two outcomes off into two different "parallel universes" like a criminal attempting to hide the evidence of a crime, but it is clear that, as far as linearity is concerned, the MWI is no improvement over the existing quantum measurement problem — despite the claims of its advocates. The same cannot be said for environmental decoherence which remains perfectly linear throughout the observation process.””

The many‑worlds interpretation merely relocates the measurement problem to the apparatus, offering no real resolution, unlike decoherence which stays linear throughout observation.
In simple terms: MWI shifts, problem, decoherence stays linear.
Key Takeaway
Recognize decoherence’s role, don’t rely on MWI alone.

A Different Perspective
MWI still leaves the core paradox of wavefunction collapse unaddressed.
![“In fact, if you have a very large volume of mass at constant density, then it is guaranteed to become a black hole if the volume is large enough — no matter how small the density! [13] This means that if we had a large volume of soft cotton wool, with a uniformly low density, it would collapse to…” quote by Andrew Thomas](https://sms4smile.com/quotes/img-quotes/5ba/andrew-thomas-21902_black-hole_in-fact-if-you-have-a-very-large-volume_1663514.jpg)
