Spacecraft & Spycraft
Hyperspace is an alternate dimension which is used for speedy travel between locations that would otherwise take longer to travel to in normal space. The entire dimension appears as a stormy environment that has a constant red hue.
Transit between normal space and hyperspace occurs through the use of a “Jump point.” A Jump point is a large energised vortex that punches a hole between the dimensions and allows objects to pass from one side to the other. To do this requires a huge amount of energy and so most hyperspace travel is achieved via a Jumpgate, though Starships that can meet the energy requirements can generate their own Jump points with use of on-board Jump Engines.
Human ships travelled through Hyperspace without fully understanding it prior to contact with the Centauri, who sold them jumpgate technology for an undisclosed price.
