A comet the size of Manhattan just zoomed into our solar system at wild speeds, and it’s only the third interstellar object we’ve ever spotted. Some scientists say it’s just a cosmic snowball, but others (like Harvard’s Avi Loeb) are dropping hints it could be alien tech on a recon mission. Stephen Hawking once warned us about attracting attention from advanced civilizations—now this space visitor has everyone side-eyeing the stars. What if he was right? #Science #SpaceMystery #Comet
