The idea of 'the Warp' or 'the void' is well established in mainstream science fiction, and has been used in lot of places. It appears on Babylon 5, for example, in a very similar way. As a tangent, is there any information on exactly HOW a 40K starship makes the 'jump' into the Warp. I have always seen the warp as ever present, with areas where the barrier between reality and the Warp is 'thinner', like a puddle on the ground, and this would mean that 'real space' doesnt actually exist in this place... but I know that ships can make their own jump without finding these weakened spots, so how is that done... is it just majik?
