I was wondering if any studies have been done concerning entangled particles where one experiences time dialation relative to the other. What I am wondering is if the entangled particles' communication will continue to be on sync with each other's time (i.e. information between the particles for an observer will seem to be exchanging back and forth through time). My curiosity is if entangled particles become entangled in time as well "space". If so, in theory, any way, it might be possible to make primative "early warning" systems that communicate microseconds into a possible future!
