Bridging is a term used in space travel when describing faster than light travel beyond standard warp speeds. Bridging is also in reference to crossing the gap, with regard to the theory that the fastest way to get from one point to the other is not a straight line but rather zero i.e. folding space and time so that both points exist at the same spatial coordinates. Tachyon Gates work off relatively the same methodology of space travel, where one Tachyon Gate folds into another Tachyon Gate at a specific spatial coordinate. In this history of space travel there hasn't been a vessel capable of self-bridging as the necessary power required far exceeds any known reactor models. There is, however, a myth that mankind had built one, the Borealis, that once the bridging drive was activated destroyed space travel in the Sol System, killing a large portion of mankind.
