Warp space is a realm capable of navigation but, at least in the scope of human knowledge, a mysterious phenomenon. There is some evidence that transdimensional rifts occur between warp space and the material universe spontaneously, though data are limited. While such rifts can be created artificially, warp travel should not be undertaken lightly. If co-ordinates aren't plotted correctly, a ship's crew can end up dead and/or so far from their intended location that they can never get back. Colliding with physical objects is a potential hazard while in warp space.
