Subspace or Hyperspace: Difference between revisions

* In ''50 Great Short Short Science Fiction Stories'' one of the short stories deal with breaking through to hyperspace only to discover that it is ''slower'' than light speed and thus useless.

* All FTL travel in ''[[The History of the Galaxy]]'' is done through a dimension/anomaly called "hypersphere". Unlike the mathematical term, which simply means a sphere in more than 3 dimensions, this hypersphere is more like your typical sci-fi hyperspace. It exists alongside normal space/time and appears to have a spherical shape (with our galaxy surrounding it). Like any sphere, it has a center, and several later (timeline-wise) novels deal with what's located there and the impact it has on interstellar travel. The properties of hypersphere are stated in most novels, with novels dealing with the nature of hypersphere going into more detail. Of note is the fact that humans are one of the few known races to have developed hyperdrives (although the discovery of hypersphere itself was a complete, and tragic, accident, involving the disappearance of the first extrasolar colony ship). Most other races have learned to use the "horizontal" force-lines in hypersphere (they connect large stellar bodies such as stars or planets) as tunnels of sorts, creating a [[Portal Network]]. While they don't need ships to travel from planet to planet, they are limited to the network, until their ships traveling on sublight can set up a gate in a new system. When humanity first encounters them, the aliens quickly adapt human hyperdrives for their own ships. Hyperdrives are made up of two generators: one to "submerge" a ship into hypersphere and one to "surface" it back to normal space. They are designed to be infallible and almost never break down.
