Following the discovery of QCI theory by Benjamin Eyrie, energy production was revolutionized. Antimatter could be drawn from parallel universes and used to produce enormous amounts of power. While not unlimited, the amount of energy that could be generated was enough for the construction of practical interplanetary spacecraft. Solar System General, Inc., was a large corporation that aided in the colonization of planets and asteroids. Following the discovery of vast amounts of copper, iron, titanium, various ores and minerals, as well as many varieties of rare Earth metals in the worlds of the solar system, interplanetary trade became a booming activity.
