Spatial Tangent

The four-dimensional aspect of the Holzmaan Effect, the Spatial Tangent is a poorly understood, yet essential component of Space Fold technologies. Its best explanation is that it is a line that passes thought infinitely close points to the curve of folded space, though this is perhaps the best interpretation of a 3 dimensional beings understanding of a four-dimensional aspect. The transposition of a vessel along this line is what allows Starliners to cross vast distances in a blink of an eye.
