Gregory Laughlin has a funny story: While he was working as a planetary scientist at the NASA Ames Research Center in the early 2000s, he was accused in the press of trying to shove Earth into a new orbit, farther from the Sun. “I got into major trouble,” Laughlin remembers in a conversation with Nautilus. […]

Consider this scenario: Suppose astronomers had tracked an asteroid, and calculated that it would hit the Earth in 2080, 65 years from now—not with certainty, but with, say, 10 percent probability. Would we relax, saying that this is a problem that can be set aside for 50 years, since people will by then be richer, […]

In the center of the photo, standing amid dry brush and trees, is something’s butt. I have 50-some animals to choose from, and I’m really not sure whose butt it is—maybe a duiker’s, a small, deer-like creature. “If you see an animal, please mark it,” the instructions say, “even if you’re not sure, or have […]

In 1972 the Club of Rome, an international think tank, commissioned four scientists to use computers to model the human future. The result was the infamous Limits to Growth that crashed into world culture like an asteroid from space. Collapse, calamity, and chaos were the media take-aways from the book, even though the authors tried hard to explain […]

Forty years ago, scientists found alien life. Not on another planet, but on Earth, in the deep sea, in places where plumes of steam and nutrients heated by volcanic activity fed entire ecologies of creatures adapted to harness chemical energy rather than energy from the sun. The discovery redefined life’s biophysical possibilities, and scientists and […]

To almost all sports fans, doping in sports is an issue of near-religious importance, says Julian Savulescu. According to the Australian bioethicist and moral philosopher, fans celebrate people of extraordinary physical ability who dedicate themselves to training to perform an athletic feat to perfection—but when they augment their abilities with drugs and enhancers, fans can […]

If you think computers have gotten really good at solving problems—like voice recognition, or self-driving cars—then your mind would be blown by what they could do if P = NP. Internet cryptography would come crashing down. Voice and image recognition would become near-perfect. Mathematical proofs would be greatly simplified. The stock market would dramatically change. […]

There’s enough hot rock to fill the Grand Canyon nearly 14 times.

The email from a professor offered an unusual spring break adventure: Come spend five days in complete darkness. To Morgan Williams, then a sophomore at Swarthmore College and a psychology major, it sounded like a great way to spend his vacation week. “I’m not really one for going to the beach,” he says. For those […]
