Please forgive any misconceptions or grevious errors, quantum mechanics and relativistic physics is something I read and think about as a hobby and not a career. My question is this, does the entanglement or two particles transcend time difference? To expand, let's say we have two communication devices, each of the quantum sort that send data through quantum entanglement. Device A stays in our current time. Device B is accelerated to relativistic speeds so that time dilates for Device B relative to real time (device A's time space). Device B by some means is decelerated. Would information sent by Device B be received in the past? A side note, I'm not entirely sure that true time travel is possible and this completely voids my question. I think it's better to think of time dilation as taking a shortcut for the dilated area. Even if we accelerate Device B to relativistic speeds, it's not in the future, it simply spent shortened the perceived travel time for the accelerated device, but it likely won't reach a future date that hasn't happened yet. In writing this I see that my original question would be impossible, but I still want to hear your thoughts on entanglement and time travel.
