Also, what to do if you ever find yourself kidnapped inside a UFO.
Second Golden Era
According to theoretical physicist and science communicator Michio Kaku, we've hit a "second golden era of space exploration" thanks to the likes of SpaceX.
Speaking to Stephen Colbert during a recent episode of "The Late Show," Kaku suggested that we could soon make first contact as a result. "I think that in this century, we will make contact with an extraterrestrial civilization," he told the show host.
But making such statements certainly attracts the attention of the kind of people that believe we don't really need to go looking at all.
"To be honest, I've get emails from people that say: 'You're wrong professor, the aliens are already here," Kaku admitted to Colbert. "They've been in the flying saucers, they have been kidnapped."
Luckily, the physicist has some words of advice for them. "I tell them the next time you are kidnapped by an alien flying saucer, for God's sake, steal something. I don't care whether it's a pen or a chip, steal something! Because there is no law against stealing from an extraterrestrial civilization."
Kaku also expanded on the most likely places we could eventually discover extraterrestrial life. "I would love it if there is life forms on Mars, maybe even microbial life, but the best bets are the moons of Jupiter and Saturn," he said.
"Europa and Enceladus have liquid oceans, billions of miles from the Sun, who would have thought? The volume of these oceans is larger than the oceans of the planet Earth."
