⚛️ What if Bell inequality violations don’t require “spooky action at a distance” after all?

1964 John Bell turns philosophy into an inequality; experiments violate it. So nature is nonlocal, or realism fails, or both. The unsolved part is the meaning; what is the thing that “connects” outcomes? #QuantumFoundations
We got lost in the measurement-problem literature—so we drew a map.
New review in Philos Mag: #decoherence + today’s main approaches, incl. many worlds, objective collapse, hidden variables & epistemic views—plus measurement in QFT.

Highlights of the before lunch session of QFTA 2025.
We had talks covering topics like Quantum Metrology, back action due to quantum tunneling, non-classicality and autonomous Maxwell demon.

Interesting.
"... Bell's theorem is not a test of local realism and violations of Bell's inequality do not rule out local realism because there are other essential assumptions."
I liked an article Sabbine wrote for a science magazine on superdeterminism.
#QuantumFoundations
I think it's a good "reasoning" test because Bell's theorem has been misstated in most publications so LLMs are likely to reproduce the mistake.
If you actually look at the maths, it is clear that Bell's theorem is not a test of local realism and violations of Bell's inequality do not rule out local realism because there are other essential assumptions. You find this in more careful papers on the topic. This is why LLMs will bring it up with a follow up question. I'm actually impressed GPT 5 answers the question correctly on first try, which most physics PHDs would probably get wrong.

It promises to be a key resource for researchers interested in both the history, and the future, of #photonics for #quantumfoundations, which formed the basis on which the modern fields of #QIST were built.

Hey, if you know of any postdoc jobs in theoretical cosmology, alternative approaches to quantum gravity, modifications of QM and/or Quantum Foundations...
Let me know!
