Researcher Says Aliens May Be Using Star Systems as Spaceships

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.

Such a civilization might want to escape the vicinity of a nearby supernova that threatens their star system’s existence. Or they might be running out of resources on their home planet, and decide to move to another part of their galaxy where resources might be plentiful. Or they could simply be explorers driven by curiosity or a sense of adventure. They might even be forced to take such action as a response to attacks from other alien civilizations.

Rather than constructing ships that would carry just a few of them through space as astronauts, these aliens could take everyone along for the ride, with their solar system traveling through space on the ultimate voyage of discovery. While the journey to another solar system in a different part of the galaxy would be a long one, since the entire civilization was taking the trip together the passing of the time wouldn’t really be noticed.

This is an astonishing proposal, but it is based on an idea that has been around for a long time. The idea of creating a “stellar engine” (a star that could be used to power space travel) was first conceived of by science fiction writer Olaf Stapledon in 1937, and the concept has always been considered sound—impractical perhaps, but not totally out of the realm of possibility.

In his theoretical study, Vidal proposes that binary star systems would make the best candidates to be converted into spaceships. The particular types of binary systems he identifies are known as spidar pulsars and redback pulsars, and each consists of a star that is smaller than our sun revolving around a dense neutron star with a powerful gravitational field.

In such systems the neutron stars create an enormous amount of energy. They do this through the combination of their rapid rotation (rapidly spinning stars are known as pulsars) and the gravitational forces they generate, the latter of which causes high-powered ejections of materials from their partner stars.

It is these forces, Vidal says, that could be controlled or redirected by an advanced alien civilization to actually propel an entire star system through space at a high rate of speed. The idea would be to take control of the pattern of ejections by the neutron’s companion star, and to point them in a specific direction. This would essentially turn that star into a massive rocket, propelling the solar system and all of its inhabitants toward the region of space they would like to explore. Making changes of direction in the material ejection patterns would allow the alien engineers to steer their moving solar systems, giving them total control over their final destination.

An alien civilization would have to be enormously advanced to have developed the technology necessary to manipulate stellar forces. But if they were, converting their entire solar system into a spaceship could be feasible and logical, Vidal argues, and in such a circumstance there would be no shortage of reasons why such a civilization might want to put this idea into practice.

Let the Investigation Begin!

It would be easy to dismiss an idea like this as 100-percent speculation, rooted in science fiction more than science reality. But it is an idea that can be investigated, which is really all that Clement Vidal is recommending that astronomers do.

In fact scientists have already looked closely at the anomalous movements of hypervelocity stars, strange objects that were apparently ejected from the center of the Milky Way after passing too close to a black hole. Astronomers have identified and analyzed 16 hypervelocity stars so far, but as Vidal readily admits none of them show movement patterns that would suggest they are under intelligent control.

Vidal is convinced, however, that binary star systems with the neutron star-small companion star arrangement would make the best stellar engines, because of their unique gravitational dynamics. In fact, he has already identified two candidates that match the characteristics of the solar systems he wants investigated. These are a “black widow” pulsar designated PSR J0610-2100, and a “redback” pulsar known as PSR J2043+1711. Both of these binary star systems are accelerating, and as of now there is no good explanation for that.

And just last year, Vidal notes, NASA’s Chandra X-ray Observatory spotted five more binary pulsar systems like these in the Omega Centauri globular cluster, a grouping of 10 million stars that are about 17,000 light-years from earth. Vidal’s idea is that the movement patterns of all of these binary star systems should be closely analyzed, to see if they show any signs of speeding up or slowing down, changing direction, moving faster than predicted, and so on.

“I see the highlighted spider stellar engine candidates and predictions as promising starting points and clues that require further attention, observation, modeling, and follow-up,” he wrote.

Should such evidence be observed, it would of course not prove these solar systems were being driven across the galaxy by aliens. But if any of them are, perhaps one day thousands of years in the future they will decide to park in orbit for awhile around our sun and stop in for a visit. Should this ever happen, the result would be the largest and most spectacular mass UFO sighting in world history, followed up by actual alien contact.
