Interstellar Comet 3I/ATLAS: Harvard Astrophysicist Suggests Possible Alien Technology Connection

Harvard astrophysicist Avi Loeb and his research team have determined that Comet 3I/ATLAS, the third confirmed interstellar visitor to our solar system, may be significantly larger than initially believed—potentially exceeding 33 billion tons in mass with a nucleus diameter over 3.1 miles. The object's unusual trajectory and non-gravitational acceleration have led researchers to consider whether it could be an artificial technological artifact potentially carrying active intelligence as it passes near multiple planets in our solar system.
