Wait, wait, wait! Why do we concern ourselves so much with the physics of antimatter, especially when we accept faster-than-light travel as "normal." It it totally impossible! If something traveled faster than the speed of light, it would arrive at its destination BEFORE anyone could see it traveling faster than light. As soon as it stopped, people on the planet would see the ship appear, and then the image of the ship reaching them from a distant star (say, 6 light years away) would reach them, precisely six years later. Plus the amount of energy required to trancend into another dimension is greater than the total energy in the universe plus all the energy that would result if all the mass was converted into energy. And, the ship would have infinite apparent mass and zero apparent size. But, since it's just a game, "I should really shut up and play!"
