I am not certain if matter can actually leave the “present” or just does a 4D transformation where one spatial dimension trades places with time such that a different inertial frame simply means the “present” is wider or thinner than our frame. This gets into a weakness I have always had regarding velocity and acceleration where some people insist you need “acceleration” to produce time dilation while my take is that you only need a luminal difference in velocity to accumulate dilation. –maybe someone will chip in and explain it to me-
I am not sure that this makes any difference since a different speed always represents a certain amount of acceleration between the frames. · Likewise, when the catalyzed reactants emerge from the cavity, they are not · emerging from our future---if they are then you and I have got to send · ourselves the lottery numbers from fifteen minutes in the future---how about · it??? (I actually tried a similar thing with the Electron Einstein-Bose · Condensate inside a superconductor disk, positing that the condensate locked in · the electron zombie state over time as well as over physical distance---no · results yet!!!) See articles about Professor Ron Mallet http://www.physorg.com/news63371210.html who intends just that using powerful circulating laser beams. He hopes to receive messages from the future when they turn on their prototype. I have written him without reply and have considered exactly the scenario you describe but even looping a transmission while inside the other inertial frame or between frames still undergoes a translation every transmission between frames. I have also had trouble getting him to respond---my recommendation to him was to cause a circular shadow inside the beam, thus creating a perfect, continuous tube of light. Is any one set up to try such a thing?
