It seems reasonable to say that if aliens truly are out there somewhere, we should encounter them at some point. While if they would be friends or foes toward us is another major conundrum, a team of physicists might know how to detect alien spacecraft in our own Milky Way galaxy.
According to new research, scientists now believe that the Laser Interferometer Gravitational Wave Observatory (LIGO) could be used for finding evidence of intelligent alien life in space. Furthermore, the large-scale physics experiment and observatory that debuted three decades ago could be used to detect alien spacecraft.
No evidence of aliens so far
Aliens haven’t been found anywhere else except in sci-fi movies, literature, video games, or cartoons. This is indeed a major issue, as it limits the trust of some scientists, who are already skeptical enough, that humanity will ever get in contact with life forms from other planets. Therefore, astronomers need to exploit new ways of finding aliens in space.
The LIGO experiment is considered capable enough to detect possible gravity waves left behind by alien spacecraft. However, it might be a problem that for the scenario to work, the alien spacecraft has to be big. Really big. Almost unfathomably big. Big as the biggest planet in our Solar System, Jupiter.
Another major hindrance that stands in the way of astronomers’ dream is that the alien spacecraft also has to move extremely fast through space. It should be able to reach about a tenth of the speed of light.
But by far, the biggest problem is that aliens weren’t discovered yet, and despite the optimism of many of us, nobody can guarantee that they truly are there, somewhere. If anybody has ever seen an alien, or if any of you is one, please feel free to tell us in the comment section!
