Lets say we mastered near lightspeed travel and instantaneous communication using quantum teleportation. Then we send the spaceship off to someplace 1 lightyear away. It turns around and for a brief moment travels twords earth at near lightspeed. During this moment the spaceship asks earth how things are goin and earth responds. The space ship reduces it velocity to 0 relative to earth now the spaceship has information about earth from 1 year in the future, because of the change in the alignment of its inertial frame, and has the ability to tell earth all about it. Can any1 see a flaw in that logic? Otherwise it seems that everythin is predestined.
