Is There Alien Debris on the Moon? Some Scientists Plan to Find Out.
Researchers want to explore the idea that microscopic particles shed by alien civilizations have accumulated on the lunar surface, making it an archive of extraterrestrial technology.
Imagine an alien civilization that runs on dazzling technologies far more advanced than our own. Picture city-size starships, planet-wide mines or swarms of solar panels that harvest energy directly from a star.
As these aliens go about their otherworldly business, the erosive forces of space wear down their infrastructure, loosening tiny bits of debris that detach and drift into the cosmos. If the civilization collapses, its remains degrade even faster. Clouds of particles might be unleashed into the galaxy, akin to the microplastics in Earth’s oceans, sprinkling countless worlds with the detritus of an extraterrestrial society.
