I know this doesnt have much to do with freespace's idea of subspace, but for all those struggling to understand some basic things about travelling faster than light, i think its important to explain, since ive seen about 4 topics today discussing jump nodes and the like:
Take a peice of paper, and draw 2 dots on it, a good few centimeters apart. Now whats the shortest distance between them? A straight line? Wrong. The actual shortest distance is 0. Fold the paper so the dots match up, it'll show that.
If u can fold space, the distance you have to travel is reduced greatly.
A lot of sci fi bases itself upon this theory.

However freespace is based up the theory that there are multiple dimensions existing, each with their own set of physics laws, different from ours. In FS1 it explained that when a ship wants to slip into the dimension of subspace, it vibrates at a set frequency, and it leaves our physical dimension and only exists in freespace till it leaves it again.
Jumpnodes are used to to do intersystem jumps because the jumpnodes form where the gravity of stars weakens the separation between subspace and real space. However this does not explain why intersystem jumps take more time than jumps in the same system. We assume that it takes less time, but we cannot explain it from what we are told in freespace. The obvious answer is that there is less distance to cover, but in distance in subspace are irrelevant of realspace distances, sine its a different dimension. In fact, it is most probable that a seperate dimension is created for each intrasystem jump, since there have been no cases of intercepting a ship in subspace jumping around a system.
Lesson : Never (
ever ) compair subspace and realspace. DON'T.
it upsets me.

If you want to write up some useful information about subspace Kitsune, write about how a ship acheives subspace.
