Astronomers have observed stars that are accelerating through space at a shockingly rapid pace. Normally this is assumed to relate to gravitational forces in some way, or to the natural emissions of the stars that might be causing them to move at unusually fast rates. But one researcher has a different idea about why some stars or star systems seem to be moving more rapidly than normally, presumably dragging their planets along with them as they go. According to Clement Vidal, a philosopher from Vrije University Brussels in Belgium who has an interest in astronomy, these traveling solar systems may have been converted into fast-moving “spaceships” by advanced alien civilizations looking to explore other areas of the Milky Way galaxy. The Solar System as UFO Assuming for a moment they developed the technology to actually accomplish such a thing, an alien civilization might have various motivations for propelling their entire solar system through space. “Two universal evolutionary motivations will make interstellar travel a necessity to any long-lived civilization: survival and reproduction,” Vidal wrote in a non-peer-reviewed paper about his concept published through Cornell University.
