Given that we have never actually defined what »time is a local phenomenon« is supposed to mean, that may or may not be true. But given that relativity puts time and space on a more equal footing than Newtonian mechanics, where you now can turn time into space and space into time, I remain pretty doubtful that something that can be summarized as »time is a local phenomenon« is likely to be interesting and correct because it seems to point in the direction of not treating time and space in a unified manner.
- EGreg 8y agoListen, space is a local phenomenon too. It is just about correlations. A lot of the nonlocal effects in De Broglie Bohm theory become classical once you consider close-by objects and neighborhoods. They are just super correlated. Why? We don’t know. But with so many correlations, you can compare way more easily between them. https://www.wired.com/2016/01/quantum-links-in-time-and-space-may-form-the-universes-foundation https://www.wired.com/2016/01/quantum-links-in-time-and-spac...
- danbruc 8y agoThis still does not answer what you mean with »time is a local phenomenon«. What feature of time is local and in which sense? And I am even more skeptical about »space is a local phenomenon«, I mean »local« means »close in space« and therefore it seems you are saying something recursive, i.e. space has some property within itself which doesn't really make sense, at least to me. So unless you can define or at least explain in more detail what you mean with »time (or space) is a local phenomenon«, we won't really get anywhere.
