Yes. It is also called the "conspiracy" between QM and SR. > I would like to hear speculations on non-locality. There are many in QM. I mean many non-localities. In example the famous 'collapse', the 'Aharonov-Bohm' effect (also with neutral particles), the EPR non-separability, and there are non-localities involving time (interferences in time, quantum beats, Franson interferometers, etc.), and also effects, like the 'delayed choice', possibly related to the 'block universe', or 'holism', or 'wholeness', or time-like non separability. And there are also 'delocalizations'(non just superpositions) in the 'weak measurement' approach (measurements which give little information). And there are - how can I say? - topological (?) non-localities too. Imagine a two-slit apparatus. You can also think this two-slit apparatus as a 'superposizion' of two *physical* complementary *pieces*. Not just hole 1 + hole 2. But something like matter void void + matter matter void of course with the right measures and shapes! Now imagine to locate one piece in a location and the other piece in another location. You get a sort of 'non-local' two-slit apparatus. Now if a photon beam goes through one of those pieces above and a correlated photon beam goes through the other piece you get an interference effect, due to the 'non-local' two-slit apparatus. Of course all the above are not 'speculations' about non-locality but performed experiments, showing several faces of non-locality. For useful speculations you can also read the Bohrian and instrumentalist Asher Peres (no physical collapse) and the 'philosopher' Suarez (a-temporal quantum)
