Raj: I know a lot of people have been having fun claiming that I said I found alien life. I want to make it clear that is not what I said. I did say that was one possible explanation. I don't think that's something to mock. Right? It would be arrogant for us to assume that we are alone in the universe. And as scientists, we need to remain open to the possibility that the truth may sound silly or far-fetched. Uh, the round Earth. Germs that cause diseases. Subatomic particles. All these at one time seemed fanciful.
So who's to say what science fiction of today will be the reality of tomorrow? Will there be colonies on Mars? Uh, matter transporters? Perhaps the Loch Ness Monster is real.
Who knows? I'm just saying that the only way science moves forward is to follow the evidence wherever it leads, even if it makes us sound crazy sometimes.
