Copenhegen interpretation or Many World Interpretation?

Click For Summary
The discussion centers on whether an experiment could definitively distinguish between the Copenhagen Interpretation (CI) and the Many Worlds Interpretation (MWI) of quantum mechanics. While many scientists currently favor MWI, the feasibility of such experiments remains contentious, with some asserting that it is impossible in principle due to the nature of interpretations versus theories. The conversation highlights the implications of measurement reversibility in MWI compared to CI, where measurement is irreversible. Additionally, the role of quantum decoherence is emphasized, suggesting that it complicates the potential for empirical tests between these interpretations. Ultimately, the debate reflects ongoing uncertainties in quantum mechanics and the challenge of defining and testing interpretations.

In principle... probably, yes. Every interpretation of a model has implications along with it, and it is just a matter of time before someone clever enough comes along and sees a way to measure the reality of one set of implications verse another.

That's not true.

Many interpretations have been deliberately cooked up so its impossible to tell the difference between it and the formalism.

In fact most (but not all) interpretations is simply an argument about the meaning of probability.

Right, so, just to emphasize: what you're calling Copenhagen is known in philosophy of science as instrumentalism, and in the context of QM is generally called shut-up-and-calculate. .

Yes and no. It is part of a group of interpretations that has observations as its primitive (philosophers likely would call it instrumentalist - although I wouldn't because it goes well beyond instruments in actual experiments) that differ purely in how the interpret probability. I would classify all those in the shut-up and calculate group.

Thanks
