The 2022 Nobel confirms reality is non-local, the culmination of 50+ years of physics, and we seem to have diddly. Where are the breakthroughs? They’re not in QC. I feel something is amiss. There’s a mismatch. Einstein was the strongest opponent of non-locality, for what? Not sure where the mismatch is exactly. Believing Einstein you’d think science is now in peril due to its non-local nature being impossible to conduct experiments. But AFAICT there’s so little interest.
- layer8 3y ago> The 2022 Nobel confirms reality is non-local No, it doesn’t do that, the public presentations around it are a bit misleading. What Bell’s theorem says is that QM is incompatible with local hidden-variables theories. In the Many Worlds theory, however, local realism is retained despite Bell’s theorem: https://physics.stackexchange.com/a/573382 https://physics.stackexchange.com/a/573382. My guess is that Einstein would have come around to that view, as it fits his philosophical thinking. That being said, the 2022 Nobel price was for the experiments conducted over a time span from 1972 to 2015, confirming Bell’s 1964 theorem. As such, there aren’t any recent major new insights. The latest experiments closed some remaining loopholes, but basically only confirmed what had already been generally assumed for a long time. All of this doesn’t change what QM predicts. It just limits the space of possible underlying theories that would explain QM.
