Thread: MWI of QM

For those who work in the physics community, how seriously is the MWI of quantum mechanics taken? Do you see any shift away from the Copenhagen Interpretation?

I don't work in the physics community, but I know what they'll say. Both the MW interpretation and the Coppenhagen interpretation are just that: interpretations. They both make exactly the same predictions, so picking one over the other is a matter of philosophy, not science.

I also am not a physicist, but yes, I would say at some point we will shift from the Copenhagen Interpretation for one of two reasons. Either we prove it wrong in some way, or we prove it right and it's no longer an interpretation it's a fact. I personally agree with Schrodinger and Einstein, it's an absurd theory.

The MWI is taken very seriously, especially at Oxford and among many who work in quantum computing. I get the attraction, but I don't subscribe.

As to the Copenhagen Interpretation, there should be some doubt about whether it represents as wide a range of scientific belief as it is taken to. See Don Howard, "Who Invented the Copenhagen Interpretation?" http://philpapers.org/rec/HOWWIT
