I had read somewhere (or imagined LOL) that this "spooky action at distance" happens due to multiverse.
Once two particles become entangled, they are entangled forever and lets say one particle is a billion-light years away.
If that particle gains a new information (charge, spin, etc) the other entangled particle HAS to take the same property. How does this information get relayed? It should happen one billion year afterwards but instead it's instantaneous. This is when multiverse theory comes into play.
When you observe this one particle one billion light year away, in essense in our "alternate" universe(s) these particles are already "entangled" and we simply "flip" onto this new universe with the two particles with the said spin and charge. Because time is considered as one of our 4-dimension, and string theory takes us into 10 (maybe 11) dimensions, through Calaubi-Yau manifolds we can "bend" this 4-dimension like we can bend a 2D object through 3D to make a "wormhole", this information or this new, "alternate" universe, rather is warped into ours.
It's like as though we have two particles with every single spin and charge and whatnot in all multiverse and once we decide to observe one particle a certain way, that ONE multiverse with the said property warps into ours. This explains the "instantaneous" information travel because there's really no "light" that travels to relay this information.

However, if that was possible it's very likely the universe (or the time-machine) would already have been destroyed due to a feedback loop.
It's called quantum entanglement. It's an incredibly strange form of quantum physics that essentially ties two (or more) particles together, where if you do one thing to one (change spin, etc.) it also applies to the other. I don't really have a full understanding of it, but that appears to be the basics of it.
