Avi Loeb is arguably the most controversial astrophysicist in the world. But he’s been a professor at Harvard for more than 30 years. So, when he says there’s a chance that an alien spaceship - disguised as interstellar object 3I/ATLAS - is headed toward Earth, people listen. I went to Avi’s home to find out why he’s willing to risk his reputation for this theory. Does he really believe it? And if he’s right, what does it mean for humanity?

*This interview was recorded on August 24, 2025. New observations about 3I/ATLAS have been made since that time.
