Interpretation for sure. Bells theory and then it being proven winning a Nobel prize to me only proves more we really don’t understand the world around us and only perceive what we need to survive. And that maybe we should be less standoffish to ideas that change our current paradigm, because we obviously have a lot to learn.

Bells inequality is a statement about math, it gives an inequality that could only be violated if there were no local hidden variables (read: if measurements were truly random). That was a statement of math, which is rigorously provable. It took experimental confirmation, but we can now say with high confidence that there are no local hidden variables (i.e. there is no information hidden that we simply cannot measure, instead the outcome is only decided the moment you measure).
Global hidden variables are still an option, but they would require much of the rest of physics to be rewritten

Didn’t Bell just put that up as a theory and it got proven somewhat recently by other researchers? The 2022 physics Nobel Prize was about disproving hidden variables and they titled their finding with the catchy phrase “the universe is not locally real”.

He proved it mathematically, but it was only recently confirmed experimentally

I see, thanks for the insight!

No problem! Interpretations of quantum mechanics are also still very much under discussion, and Bell’s inequality only says that there are no local hidden variables. While QM very accurately describes observations so far, it’s by no means solved, and there’s a good chance that a new theory will upend much of it in the future
