For arguably the most famous physicist on Earth, Stephen Hawking—who died Wednesday in Cambridge at 76 years old—was wrong a lot. He thought, for a while, that black holes destroyed information, which physics says is a no-no. He thought Cygnus X-1, an emitter of X-rays over 6,000 light years away, wouldn’t turn out to be…

Perhaps the greatest outrage in modern robotics is the continued non-existence of the robot housekeeper. Is it really so much to ask for a robot that sweeps and mops and brings you pills on platters, like Rosie from The Jetsons? Actually, it kind of is a lot to ask: A robot that can do even…

Activate satellite view in Google Maps and head to the Las Vegas strip, and you'll see it: a strange smattering of Y-shaped buildings. Mandalay Bay. Monte Carlo. Treasure Island. The Mirage. Their blueprints put gambling at the center of everything, funneling visitors past slot machines and card tables whether they're en route to a show,…

For sale: orbiting space station. Room for eight. Fantastic views of Earth. Commercial opportunities for zero-g manufacturing, research lab, or floating hotel. Cost: $3 to 4 billion a year. Any takers? President Trump’s new budget request, released Monday, directs NASA to leave behind the International Space Station and explore the moon as a first step…

Boy, it’s hard to stay optimistic these days, what with the impending doom of our species at the hands of … our species. Namely, human-caused climate change. Climbing temperatures are ripping apart ecosystems, and rising seas are already forcing people from their homes. If an asteroid was going to destroy our planet, now would be…

There's a very good reason that humans are still using gas-powered cars. Despite the negative side effects of combustion—it releases not just energy, but carbon dioxide—the simple fact is that you can get more energy out of gasoline than you can from other energy sources. A typical car can travel 30 miles on just one…

“Dear everyone,” wrote Rocket Lab CEO Peter Beck during a reddit AMA in April, “I'm not building a bigger rocket any time soon.” Beck seems to get asked about expansion a lot. He and his Kiwi-US space company don’t build craft whose names end in “heavy.” Their rockets don’t land after launch. They’re only about…

Here’s how it could go: Some day in the future, it’s routine for every young woman of a certain age—for argument’s sake, let’s say 21—to undergo a procedure to snip off a piece of tissue from one of her ovaries. Her doctor slices up the tissue into a half-dozen or so microthin sections; these are…

I don’t think sci-fi saw this coming. For so long, futuristic books and films have promised us robots like C-3PO that translate alien languages and assist us in hijinks. Or ones like Rosie that clean our houses. Or, on the other end of the spectrum, robots that level our houses and destroy humanity. Looking at…

The little robot finger’s favorite color is blue. Wave a handful of blueberries in front of it and the finger will follow, transfixed. If you’re wearing a blue shirt, congratulations, you’re its new best friend. If you painted everything around it blue, the robo-digit could well have a heart attack. You can program a robot…
