Entanglement.

Two or more quantum objects are entangled when they share a common quantum state and nonlocal correlations after an event or interaction. Whenever one of those particles gets perturbed, the others will know instantly, even if they had no time to exchange signals at the speed of light.

This phenomenon is easily explained now we know the whole spacetime concept is meaningless for things that go at c: All carriers from a common emission point feel directly connected. Carriers can't evolve going at c, so it doesn't matter if they went lightyears apart in opposite directions, emission and detection points form one simultaneous ensemble from their point of view. When we detect a carrier related to an entanglement event, we're not intercepting a messenger; we're dealing with the entanglement event directly, as if no time had elapsed.

We think that a matter particle has to start sending information at c the moment we perturb it or detect it, but the entangled particles were exchanging information instantly the whole time: the carriers that shape their fields don't experience any spacetime intervals.

So we can't trick information carriers playing time games, because they see our time intervals as a single instant and, this way, they'll be always ahead of our intentions. We call “spooky action at a distance” something they'd rather call “action at spooky distance” (or “action at spooky time”, for that matter). Whenever there are things connecting events at c, they're sharing the same conditions in a way that, if they don't tell a consistent story, then the entanglement event never happened.

The fact that we see a process where they see a simultaneous event explains why we need weird spacetime mechanisms to describe their connection (the forward and backward waves used in the Wheeler-Feynman absorber theory and QM's transactional interpretation, or the retroactive Parisian zigzag entangled particles would perform over the Einstein light-cone, as proposed by O. Costa de Beauregard), but all information carriers that create our reality right now are correlated with other carriers that bring the same consistent histories to other times and places in the universe.
