Okay, wild space theory alert: Harvard’s Avi Loeb is saying that the new interstellar comet 3I/ATLAS could actually be an alien craft. Most scientists are like, “nah, it’s just a comet,” but Loeb points out its weird path through our solar system and says we shouldn’t rule out anything until we get more data. He even wants a Richter scale for alien risk! NASA says it’s not a threat, but still… what if? #Science #3IATLAS #AlienLife
