Are the fastest-moving stars in the sky spaceships flown by aliens?

The question remains the cornerstone of the modern era space exploration. A new hypothesis suggests advanced alien civilisations 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 In a recent unpublished paper, philosopher Clement Vidal from Vrije University Brussels proposes that long-lived alien civilisations could manipulate binary star systems for galactic exploration. 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. This new approach suggests astronomers could look for unusually accelerated binary systems as potential indicators of advanced civilisations.
