Avi Loeb: Do the Anomalies of 3I/ATLAS Flag Alien Technology or an Unfamiliar Interstellar Iceberg?

• Avi Loeb: Do the Anomalies of 3I/ATLAS Flag Alien Technology or an Unfamiliar Interstellar Iceberg?

  As I explained in an interview with Peter Doocy on “The Sunday Briefing” of Fox News yesterday (accessible here), the foundation of science is based on the humility to learn, not the arrogance of expertise. When comet experts argued that 3I/ATLAS must be a familiar water-rich comet as soon as it was discovered on July 1, 2025, they behaved like artificial intelligence systems which reflect their training data sets. For decades, the data set that established comet expertise included icy rocks in the solar system. My point is simple. Humanity launched technological objects to space and we must add them to the training data set of comet experts when studying interstellar objects.

  On January 2, 2025, the Minor Planet Center — officiated by the International Astronomical Union to catalog space objects, identified a “near-Earth asteroid”. A day later, the officials realized that this “asteroid” follows the trajectory of the Tesla Roadster car, launched to space by SpaceX in 2018 as a dummy payload on the Falcon Heavy rocket. They immediately removed the object from their asteroid catalog, realizing that it is not a rock but rather a car.

  Elon Musk is probably not the most accomplished space entrepreneur in the Milky-Way over the past 13.8 billion years. There are about a hundred billion stars like the Sun in the Milky-Way, and roughly a tenth of them host a habitable Earth-size planet. If you roll the dice on billions of Earth-Sun analogs, surely you could get more accomplished space entrepreneurs on some exo-planets. Most stars are billions of years older than the Sun, and during a billion years our Voyager spacecraft with its 1970s technologies can reach the opposite side of the Galactic disk. This implies that there was plenty of time for interstellar artifacts, potentially more advanced than Voyager or the Tesla Roadster car, to reach the Solar system from interstellar space. Would comet experts recognize these visitors as technological artifacts if their training data set includes only icy rocks?
