A new study suggests that extraterrestrial civilizations could use wandering planets to help entire populations escape some “looming existential threats”, or perhaps spread the seeds of that civilization to distant worlds.
While transporting large numbers of living beings across the vastness of space to distant worlds might seem like a daunting task to perform, even for a civilization more technologically advanced than ours, a recent study suggests it could be accomplished without the use of spacecraft. space.
In her new paper published online by Cambridge University Press, Irina Romanovskaya, professor of physics and astronomy at Houston Community College, points out that “extraterrestrial civilizations may use wandering planets as a means of interstellar transport to reach, explore and colonize planetary systems.” .
A wandering planet is essentially a planetary-mass interstellar object that does not have a host system.
Noting that floating planets can provide “constant surface gravity, vast amounts of space and resources”, and that “technologies can be used to modify the movement of wandering planets”, the researcher suggests that alien civilizations could use such planets as gigantic arks.
