Inter-dimensional travel greatly reduces the amount of time it takes to go between two points. Yet it does not do so in the linear sense. Consider the 13 dimensions. Most of your existence is bounded by height, width, depth and time. Nine more dimensions exist besides these. Because these dimensions exist in relation to the spatial and temporal ones, a ship may move from these spatial dimensions into one of the higher dimensions and re-enter the spatial dimensions at another point.

The idea may be illustrated using pieces of paper as a model. You may wish to move from point A, near one end of a piece of paper, to point B, near the other end. You can do by tracing a path across that same piece of paper in those three dimensions contained by the paper. Add the fourth dimension of the amount of time the tracing of such a path takes, and you will see the traditional method of your travel.

But if you consider the same problem of movement from point A to point B on the paper, and you add a second piece of paper to the thought experiment, you will see that there is another way to accomplish movement. For you may trace a path from point A to a position exactly opposite point A, on the second piece of paper. And then if you crumple or fold the first piece of paper to bring point A and point B close to one another in relation to the second piece of paper, you may trace a path on that second piece of paper which is constrained by a much smaller amount of the fourth dimension --- time. Then you may cross from the second piece of paper back to the first piece of paper at point B, having accomplished your movement from point to point in a minimum amount of time.
