The proposed model: binary systems as cosmic propulsors
The model theorized by Vidal imagines a binary system composed of a neutron star and a low-mass star in close orbit.
This configuration, according to the scholar, offers great flexibility for the manipulation and control of the system’s trajectory.
The key would be the use of advanced technological devices capable of ejecting material from the star asymmetrically.
Through controlled material release, for example using irregular magnetic fields or localized surface heating, a propulsive thrust would be generated.
The consequence would be a shift of the binary system in the opposite direction of the material ejection. Maximum efficiency would be achieved by placing such devices near the neutron star, where the extremely high gravity could be harnessed as an energy source.
By alternating the activation of the propulsive device at specific points in the orbit, an alien civilization could precisely direct the binary system or gradually modify its trajectory.
Real binary systems and analogies with the theoretical model
Some binary systems observed in the cosmos seem to have characteristics analogous to the theoretical models described by Vidal.
Relevant examples include “black widow” pulsars like PSR J0610-2100 and “redback” pulsars like PSR J2043+1711, where a neutron star interacts with a low-mass companion star. Although it is unlikely that the observed accelerations in these systems are caused by alien technologies, such phenomena deserve further scientific study to better understand the dynamics at play.
Potential purposes of such alien technologies
The possibility that an alien civilization could manipulate a binary system opens up fascinating scenarios.
Among the hypothesized purposes are:
- Interstellar travel, using stars as propulsors to explore natural resources in other galactic regions.
- Evading cosmic catastrophes, such as imminent supernovae, which could pose an existential threat.
- Adaptations to survival needs, ensuring stellar mobility that would allow a civilization to avoid dangers or exploit more favorable conditions elsewhere.
Critical evaluation and future perspectives
Vidal’s work, although not yet subjected to peer review, offers insights for innovative discussions. These hypotheses stimulate not only the debate on potential alien technologies but also reflections on the limits and possibilities of our future engineering capabilities in space exploration.
