There are no mainstream scientific theories that support this idea of slipstream. A computer selects the “correct” path 50% of the time, but due to intuition, a human picks the correct path 99.9% of the time. Before the pilot makes that decision, both paths are simultaneously the correct and incorrect route, and it is the act of choosing a path that forces one to be correct and the other to be incorrect – if this made you think of Shrödinger’s cat, that does seem to be the basis for this concept. Any time a pilot reaches a fork in the road, he has to guess which is the correct path to take to continue along toward his desired destination. These strings are in constant flux and form a tangled mess of intersections and divergent paths. Slipstream is a form of interdimensional highway in which ships ride a series of slipstream “strings” – the unseen connections between all objects in the universe. We’ll consider the slipstream seen in Gene Roddenberry’s Andromeda, where it is “not the best way to travel faster than light, it’s just the only way,” as per the show’s protagonist. The concept of slipstream can be found in such works as Star Trek, Doctor Who, and the Halo video game franchise, but there is no widely-agreed upon definition of what slipstream is or how it works beyond it being a means of FTL. Still, the fact that a theoretical physicist devoted a large portion of his life in pursuit of a theory that could lead to a means of space travel lends the concept of hyperspace a little more credibility than if it were simply the fancy of a sci-fi writer. The theory uses a mathematical model that calls upon six or more dimensions in an attempt to resolve incompatibilities between quantum mechanics and general relativity, but Heim’s ideas have not been accepted in mainstream science. Physicist Bukrhard Heim proposed a theory in 1977 that FTL travel may be possible by using magnetic fields to enter higher-dimensional space. Before making a “hyperspace jump,” calculations must be made to find the matching coordinates between hyperspace and normal space in order to know when and where to exit hyperspace at the desired normal space destination.

Specific coordinates within hyperspace have corresponding coordinates in normal space, but the distance between those two points will be shorter in hyperspace, allowing for a faster journey.
