Hi everyone! A new paper by Wharton & Price was submitted to ArXiv ten days ago (https://arxiv.org/abs/2507.15128). There, they discuss... -

DrChinese replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.From Wharton and Argaman, discussion of retrocausal models. This is more what I am familiar with from Ken, and I think this is a good...

DrChinese replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.1. There is no science to support this statement. Correlating outcomes from Alice, Bob and Charlie is no more "postselection" than any...

And such analogies are useless if they can't explain the actual experimental results. Which they can't if they use classical systems...

Not if you want to explain Bell inequality violations. None of the classical examples can do that. Indeed, since you mentioned...

DrChinese replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.My point is that the CL hypothesis is completely invented and has no applicability whatsoever to this quantum scenario. There isn't...

Are you familiar with these experiments? https://doi.org/10.1038/nature15759

DrChinese replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.1. Just pointing out, from the Price/Wharton paper: "The sensitivity of CL to the spacetime location of the central vertex [Bell State...

But isn't it straightforward to construct a retrocausal hidden variable theory that reproduces the quantum predictions of delayed-choice...

DrChinese replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.Great question! I'm not sure I can answer it. But generally I agree that some kind of mechanism might exist if you bring...

DrChinese replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.Well, all experiments originated on the planet Earth (or the universe for that matter) technically exist in a common light cone. If...
