yup, basically space/time warps, not just in 4 dimensions but in others as well, around gravitational masses, a straight line through space/time enters a separate realm like a stone skipping off the surface of reality but in multiple dimensions... aaargh trying to put into words how it works in my head is hard... hence dolphin and whale minds as pilots. or rather the ship is now their body... some mad geniuses tried cephalopods, which are better at it, but the mind connections made the humans insane( sorry wrote this for a game years ago and it got stuck in my head a bit)As long as we assume higher dimensions to be still Euclidian space, distances in higher dimensions are equally or even further part than in the lesser dimension. For your idea to work, we would have to assume, that higher dimensions don't follow the properties of Euclidian space and distances are therefore quite different to distances in Euclidian space and that there could be a shorter distance because it is a different kind of space.
