Bob Yirka is a research scientist at Phys.org.
A team of physicists affiliated with several institutions in the U.S. collaborated on a paper that discussed the possibility of using the Laser Interferometer Gravitational Wave Observatory to search for evidence of aliens. The paper was posted on the arXiv server.
Over the past several decades, astrophysicists and sci-fi enthusiasts alike have grown increasingly frustrated with mankind's inability to detect the presence of life outside of planet Earth. Based on the billions of planets that have been discovered around the universe, and the fact that life exists in one place on Earth, there should be life somewhere else.
The problem is that scientists haven't found enough evidence to support it. New and more exotic ways to search are being called for by prominent scientists.
Science has advanced to the point that gravity waves can be detected using technology such as LIGO. It is possible that aliens could leave gravity waves in their wake that could be detected here on Earth using such technology, according to them.
The factors that might be involved in such a scenario were imagined by the researchers. They took the size into account. It would have to be large enough to generate waves that could reach Earth.
They showed that it would have to be moving very fast. It would have to be very close. Researchers at LIGO should be able to spot gravity waves if they occur.
If aliens use warp drives, scientists on Earth should be able to spot them using the same technology, because gravity waves would also be generated.
There is more information on the search for intelligent life in giltational wave signals. There is a book titled "arxiv.2212.02065."
