Based on a research revealed within the Worldwide Journal of Astrobiology (opens in new tab), aliens may use rogue planets—wandering worlds which have both been knocked from the system they originated in like a snooker ball by some gravitational occasion, or had been fashioned externally—as alternate options to spacecraft.
The research comes from a professor of physics and astronomy at Houston Neighborhood Faculty named Irina Romanovskaya, who advised Motherboard (opens in new tab) that, since rogue planets are arduous to detect within the interstellar darkish between methods, there could also be a considerable variety of them on the market. “This will increase the possibility that some superior extraterrestrial civilizations, in the event that they exist, would possibly hitch a experience on free-floating planets,” Romanovskaya mentioned. “Which is why I name such hypothetical civilizations Cosmic Hitchhikers.”
Whereas they would not be drawing vitality from a star like common planets, apparently these nomad worlds may nonetheless be liveable. They may have subsurface oceans, atmospheres with sufficient hydrogen to protect them, and sufficient residual core warmth to offer vitality for a considerable time period.
Appears like a fantastic concept for a videogame, and certainly there have been video games about rogue planets. Starquake, first launched on the ZX Spectrum in 1985, had you making an attempt to stabilize a rogue planet earlier than it imploded, and Metroid Prime 2 was set on a rogue planet with a darkish extradimensional twin, which isn’t an idea that has fairly a lot foundation in science.
Romanovskaya’s speculation relies on sounder rules: that rogue planets have benefits over spaceships like coming with their very own assets and habitats, and never needing synthetic gravity. They may additionally present an escape for inhabitants of an ageing system, who would possibly even use the push from a dying star to propel a world on the perimeter of their system into the depths of area.
From there, it is a matter of ready till you get shut sufficient to a different system with a liveable world, like ours, after which utilizing common spacecraft to make the shorter soar. As Romanovskaya mentioned, “There aren’t any site visitors lights within the Galaxy. If the Photo voltaic System occurs to be in the best way of some free-floating planet, the planet won’t cease on the purple gentle. It’s going to fly proper by the Photo voltaic System.”
One ultimate concept from Romanovskaya’s research instantly suggests an intriguing videogame: a rogue planet utilized by alien hitchhikers who deserted it, or did not survive the journey, would possibly find yourself floating on the market in large orbit. As Romanovskaya writes, “If a free-floating planet carrying extraterrestrial species or their applied sciences had been gravitationally captured by a planetary system with the assistance of extraterrestrial applied sciences, then the captured free-floating planet would maintain interstellar travellers or their artefacts. Subsequently, extraterrestrial artefacts would possibly exist on some captured free-floating planet residing as wide-orbit planets within the outer areas of planetary methods.”
The thought of exploring a lifeless rogue planet on the perimeter of the Photo voltaic System to uncover alien tech feels like one thing proper out of Mass Impact, or maybe Useless House. In fact, if it ever occurred in actuality I would quite it did not resemble Useless House fairly a lot.
