The centuries-long history of understanding black holes

Very little about black holes, among the strangest objects in the universe, is straightforward.  Scientists have a more complete conception of these mind-bending objects than ever before, by studying the massive ripples black holes create in spacetime and learning about how they form. But the brief history of humanity’s understanding of black holes was rocked… Continue reading The centuries-long history of understanding black holes

The World’s Massive Need For More Solar Panels Has One Shiny Catch

There’s a major catch to the world’s need for solar panels, a new analysis suggests. The booming solar panel market – which is critical for a clean energy future – could demand close to half the world’s aluminum by 2050. Thankfully, there are ways we can mitigate this.    Unlike more precious metals, such as… Continue reading The World’s Massive Need For More Solar Panels Has One Shiny Catch

How one person can control a swarm of 130 robots

Last November, at Fort Campbell, Tennessee, half a mile from the Kentucky border, a single human directed a swarm of 130 robots. The swarm, including uncrewed planes, quadcopters, and ground vehicles, scouted the mock buildings of the Cassidy Range Complex, creating and sharing information visible not just to the human operator but to other people… Continue reading How one person can control a swarm of 130 robots
