I understand if this question sounds juvenile, because I thought of it after seeing a science fiction movie called Clockstoppers. In this film, a device (stopwatch) is used to speed up the molecular motion of an person body so that from their frame of reference, the rest of the world has slowed to a crawl (or stopped altogether). In reference to the Twin paradox, if instead of sending one twin traveling in a spaceship at relativistic speeds while the other remains on Earth, would it be possible to vibrate the particles of one twin so that they oscillate at a frequency close to that of the speed of light to create the same age asymmetry while both twins are located on Earth? Is interstellar travel the only way to achieve the age asymmetry? Would the particles constituting the twin have to be moving coherently (relative to the twin as a whole)? I am not sure how the device works in the movie (I assume deus ex machina) or what the creation of such a device would require. I have no background in physics so please forgive me if this scenario violates a fundamental law or understanding. Thank you.
