As I mentioned, should a pseudomonopolar drive prove feasible, it would be possible to leave and re-enter our space-time continuum by using the drive to propel a vessel through the light barrier and into the trans-light state. It occurs to me that, in such a case, the vector chosen could be quite significant. As you sit reading this, you are traveling at a significant percentage of the speed of light... a combination of the vectors involved in the rotation of the Earth on its axis, its orbit around the Sun, the Sun's orbit around the galactic core and the galaxy's movement through the universe. These various motions (some perhaps canceling out others) result in a net vector, and a net velocity.

So, of all the possible vectors which could be chosen, two could have special significance; moving "along" the net vector would give a vessel a "head start" on attaining light speed, at which point time ceases to pass, while moving "against" that vector would be to approach Absolute Rest, in which state time passes infinitely quickly, according to Einstein. But if, in the course of accelerating along one of these two "special" vectors, one enters the trans-light state, then one can be said to have "dropped out" of our material universe in either a "forward" or "backwards" direction.

Imagine standing on a long, flat-bed train traveling at a fixed velocity, and then either running in the direction of travel, but at a higher velocity, and jumping off, or running backwards, against the direction of travel, before jumping off. In the first case, if one could rejoin the train before any time has passed, one would find oneself closer to the front of the train. In the latter case, one would find oneself nearer the caboose. The analogy is not perfect, but I hope it serves to make my point -- that leaving the space-time continuum by accelerating into the trans-light state along the already-existing net vector of travel, or against that vector, should mean it is possible (inevitable maybe) that one would "rejoin the train" -- i.e. re-enter the material universe, at a point either "ahead of" or "behind" the point of departure.
