The Mysterious Case of the Superfast Stars: Are the fastest-moving stars in the sky spaceships flown by aliens...!

In a recent unpublished paper, philosopher Clement Vidal from Vrije University Brussels proposes that long-lived alien civilizations could manipulate binary star systems for exploring the galaxy.

Are we alone? The question remains the cornerstone of the modern era space exploration. As heated debate continue to rise over the authenticity of UFO sightings and becoming multiplanetary species, a new paper has added fuel to the fire.

A new hypothesis suggests advanced alien civilizations might navigate the galaxy by steering their binary star systems, offering a novel perspective on potential interstellar travel methods.


In a recent unpublished paper, philosopher Clement Vidal from Vrije University Brussels proposes that long-lived alien civilizations could manipulate binary star systems for galactic exploration.

This unconventional approach could address various motivations for interstellar relocation, such as escaping impending supernovas or seeking new resources.

Vidal's theory focuses on binary systems consisting of a neutron star orbited by a low-mass companion, which he argues provides optimal flexibility for steering and propulsion. The proposed method involves ejecting material from one star asymmetrically, creating thrust to move the entire system in the desired direction.

The concept builds upon previous investigations into "hypervelocity" stars as potential signs of alien intervention. However, Vidal's approach expands the search to include binary systems, which comprise the majority of stars in our galaxy.

Intriguingly, real celestial objects exist that exhibit characteristics similar to those described in Vidal's model. The "black widow" pulsar PSR J0610-2100 and the "redback" pulsar PSR J2043+1711 both display significant accelerations, though their origins are likely natural.


While the idea of star-steering aliens remains speculative, it offers a fresh perspective on the search for extraterrestrial intelligence (SETI).

Traditional SETI efforts focus on detecting radio signals or technosignatures. This new approach suggests astronomers could look for unusually accelerated binary systems as potential indicators of advanced civilisations.

Critics may argue that the energy requirements for such stellar engineering would be astronomical. However, proponents contend that sufficiently advanced civilizations might possess the technology to harness the immense gravitational energy of neutron stars.

As our understanding of the cosmos expands, so too does our imagination of what alien life might achieve.

While Vidal's hypothesis remains unproven, it challenges us to consider new possibilities in our ongoing search for signs of intelligent life beyond Earth.
