One experiment suggests that time is an emergent property of quantum entanglement. [1] "A static, entangled state between a clock system and the rest of the universe is perceived as evolving by internal observers that test the correlations between the two subsystems. We implement this mechanism using an entangled state of the polarization of two photons, one of which is used as a clock to gauge the evolution of the second: an "internal" observer that becomes correlated with the clock photon sees the other system evolve, while an "external" observer that only observes global properties of the…

The position that time is not a localized phenomenon is preposterous. Given the observations of relativity and the effect that local gravitational force has on passage of time, and more recent experiment and theory about time actually arising as an effect of quantum entanglement (https://arxiv.org/abs/1310.4691), to presume in the context of such a big, extremely-theoretical idea that time is not local is plain nuts. It's not so hard to imagine that the rules of relativity are imposed and that outside of that imposition, they don't exist or are discontinuous to some degree. Indeed, it doesn't…

Or you could just, you know, check the published experimental results: http://www.technologyreview.com/view/512281/chinese-physicis... Physicists are increasingly convinced that time is an emergent property that arises due to low level quantum effects, principally entanglement [1]. The experiment in the Ars Technica article is the equivalent of the universe using lazy evaluation. It's really not so mysterious if you think outside the box of classical physics. Regarding sending information back in time, from what I've read physicists are divided on the issue. Most agree that sending matter…
