What is 3I/ATLAS really? I keep hearing about this ancient alien object speeding toward our Sun… that some scientists say might be “alien technology”. So I emailed one of the world’s most important astrophysicists, Dr. Alex Filippenko, to learn what’s real. And no, it won't hit us… but there are nearby asteroids that might!
