In this interpretation the universe is 100% classical, but instead of being one universe there is a VERY large number of them, all classical and weakly interacting with each other. In particular each particle is classical, but is repelled by its "copies" in the other universes.

This is able to replicate a lot of the most weird effects of quantum mechanics. For instance, classically a particle is not able to overcome a potential barrier if it doesn't have enough energy to do so.

But in this interpretation the particle would be repelled by its copies, so it has a non-zero chance of getting enough of a kick to jump on the other side of the barrier, producing the phenomenon we usually call "quantum tunnelling".

Another effect replicated by this model is the "zero point energy". In this interpretation this comes to be because the particle would like to sit at zero energy, but so do all of its "copies", and since they repel none of them can really sit at zero energy.

If you want, in this interpretation the very fact we see quantum effects is evidence of parallel universes!

At first I was very skeptical, until I realized that it is not individual particles interacting with their copies, but whole worlds interacting with each other in configuration space. Which is bizarre, but at least lives in the same space as normal QM.

Thanks for sharing the paper, it‘s interesting to see how this interpretation is applicable to a set of phenomena. I don’t see how this is compatible with quantum information, classical systems remain classical even if a huge chunk is unknown. Also I don’t quite like the misuse of „evidence“.

That's a pretty fun idea 😄
