Short cuts through space time. These have become the highways of the empire. Once created they requires very little energy to maintain and provided a much cheaper option of traveling from solar system to solar system. While they are stable there are regulations to keep them several AU away from any populated plant or Dyson structure so if there is any catastrophe all that will be lost is the worm hole. Still these structures are protected and maintain by the militarily and have a substantial toll for their use. However it is much cheaper than the exotic matter needed to power a warp drive. While matter can pass either way through a worm hole the ones created are only wide enough for one large ship to pass through so there are 2 worm holes for each route to allow traffic in both directions. Major ports have several worm holes allowing transportation to may other systems and more “lanes of traffic” for popular routes. There still is a limited amount of worm holes as one requires the creation of 2 black hoes at its openings and a large amount of negative matter.
Creation of Worm Holes
Creation of an artificial worm hole requires 2 black holes that spin. This spinning creates a doughnut shape mass at the center that warps space time. Once the black holes are linked via a worm hole they are stabilized with a cylinder of negative matter negating the gravitational forces allowing ships to pass through the hole with out being tor apart.
