Hyper space itself was best considered as a compressed dimension which corresponded on a point-by-point basis to normal-space but placed those points in much closer congruity and so "shortened" the distance between them. In fact, there were multiple "bands," or associated but discrete dimensions, of hyper space. The "higher" the band, the shorter the distance between points in normal-space, the greater the apparent velocity of ships traveling through it . . . and the higher the cumulative energy cost to enter it.
