Many world interpretation on test Is there any experiment conducted to prove Many world interpretation of Quantum mechanics?
If it can't be proved why we should take MWI seriously? Recently I read some papers of Max Tegmark who is an advocate of MWI and avoids the lack of experimental prove.
I think this is the same question as mine.
What about the two arxiv papers this and this?
 A: MWI does not predict anything which could differentiate it from other interpretations of quantum mechanics. Otherwise it would be called theory rather than interpretation. The question of choosing particular interpretation is philosophical rather than scientific. If you dislike MWI you likely to choose another interpretation which would be similarly unprovable.
The main advantages of MWI are that it extends the area of applicability of the usual laws of quantum mechanics, and postulates that there are no distinguished observers.
The main disadvantage is that it postulates the existence of unobservable entities, far exceeding the observable domain.
It is also objectively deterministic but subjectively indeterministic, compared to totally deterministic Bohm mechanics interpretation and objectively indeterministic Copenhagen interpretation.
A: Hermetically contained parallel universes are one/observer. Given leakage, one suspects gravitation leaks first. The Hubble deep field denies universal gravitational lensing distortions.  Anything can be explained by curve-fitting.  Science begins with the arrival of falsifiable prediction.  Recently in the lay literature,

Not that I know of, but Max Tegmark did propose an experiment that would prove the Many Worlds Interpretation to be the right one.
It is described on page 5 of this publication (thanks to @JoshuaLin in this question):

The only caveat is, that it would be hard to obtain consensus within the physics community.
