I love your twist on EPRB, Avshalom. Entangling the detector direction via beam splitters and post selection is interesting. [Aside: I think you have a typo on p 5, second paragraph. Don’t you mean to “Place detectors on the remaining three ‘up’ SGM exits” instead of “the remaining three ‘down’ SGM exits” in order to complete the measurement for each particle? Also, check “Sourc” in Figure 2.]
Let me inquire concerning your view of the block universe implications of this work.
On page 1, you seem open to the block universe ontology when you characterize TI and TSVF as “novel interpretations of quantum mechanics.” Both of these interpretations explain space-like correlated outcomes that violate Bell’s inequality by allowing information about experimental outcomes (or detector settings) to be available to the entire history of the experimental process (and in some cases, beyond!). Of course, this implies the “co-reality” or “co-existence” of the past, present and future, i.e., block universe.
On page 1, you say these interpretations “render non-temporality the key for understanding QM’s other unique features.” That seems to agree with Cramer who notes that the backwards-causal elements of his theory are “only a pedagogical convention,” and that in fact “the process is atemporal” (1986, 661). But, immediately thereafter you write, “Indeed, once effects are allowed to go sometimes backwards in time, …” and on page 8 you speculate that “causal effects go on both time directions” in the quantum realm. These comments sound like you’re viewing the process in some meta-time.
What is your view of the block universe implications of these interpretations? Do you subscribe to meta-time? Or, do you view these QM processes in a block universe “non-temporally?” Or, are you considering other options?
