Yes this is the idea (and I think Demystifier did understand correctly too). The point being that the super-classical correlations only become apparent when the two results have been brought back into contact and compared, so until that happens the possibilities can sort of ride along in their...
So does macroscopic realism cover any many world or multi-timeline trickery? Like i recall a demonstration of "saving locality" by having each of the two separated bell measurements create a bubble where both possible results (like spin up and down) exist simultaneously. Then when the two...
Anyone interested enough to not ignore this paper, by any chance? :smile: I'm not familiar with anything quite like it, although to me it feels like a kind of cellular automaton pilot wave theory. Does anyone see how it manages quantum strength correlations without non-locality?
Holy dang that's a name I haven't heard in a while. Last blog post before this one was June 20...2018! Says something a little sad about the state of high energy particle physics today though. :frown:
I have to agree with Demystifier and others here that QBism has always been a tad baffling, tbh. It's hard for me to understand its core identity beyond "we don't like any of the other qm interpretations out there." I'm also not sold on using math/science to prove that something can't be...
Maybe I'm wrong but I thought the TI says that in such a bell test there is an electromagnetic beam of expectation value = 0. The detectors are basically in a metastable state where tiny random perturbations from the environment will break the symmetry and knock the detector into one of the two...
You are absolutely right about this; my apologies for a poor choice of words. I was trying to suggest that the TI has the same issues with how it treats (or rather doesn't treat) such foundational problems in general. However, I didn't defend any other criticisms in my post (and I'm not sure...
I’ve been following some of the discussion on here about the Thermal Interpretation, and I’ve reviewed the linked papers. I like the idea of positing expectation values, rather than eigenstates, as primary, and taking something like a fluid mechanics approach to quantum physics. In the end...
There is a de Sitter–Schwarzschild metric wikipedia page that seems relevant to this question. For example, it describes scenarios where the black hole and cosmological horizons have merged:
Sorry to say I can't add much to the discussion on this topic but there is literature out there about...
Unless you're going to modify quantum mechanics with something like GRW's spontaneous collapse theory then I'm afraid you're stuck with superposition as a general principle. And since no deviation from linearity has shown itself despite steady progress towards larger and more complex...
I don't think this criticism of the experiment is warranted, from how I take the paper, at least. IMO it spawns from too literal an expectation for the Wigner's friend gedanken experiment aspect of it. It's more like a formal proof of concept, using single photons and a setup where everything...
Thanks for the detailed reply, and, of course, you're right about their conclusion in the paper. I was a little confused because they were saying they deal with those two theories at the end. Honestly I still find some of the arguments in that paper hard to follow, not with the math but just...
Just wondering to which result this is referring?
https://arxiv.org/abs/1607.07871 "Is a time symmetric interpretation of quantum theory possible without retrocausality?" maybe?
I think in that result they say it doesn't apply to Everett (MWI) or Bohm (although I may be misreading it, or...
