The ways large asteroids could kill us — Large asteroids definitely present one of the most colourful and chaotic possible apocalypses. Such an impact would cause quite a cinematic conclusion, combining a plague of wind, tsunamis, heat, and other terrors into a horrible death-fest.
Aliens don’t seem to really care about us — Well, nor do our ‘leaders’, but in the largest survey of its kind, astronomers scanned 5600 stars in search of these optical signals — and they found… absolutely nothing. Nada. Zilch. Here’s what that means to SETI and the ongoing hunt for alien intelligence.
NASA on the ice — Tama, a Getty photographer, spent a week last month with a NASA crew during Operation IceBridge, the agency’s campaign to measure changes in the planet’s ice sheets and glaciers. NASA spends 10 weeks each spring in the Arctic and six weeks each fall in the Antarctic when ice levels are the highest. The Arctic crew used a pair of laser altimeters to measure the elevation of the ice, and three radars to measure the snow (one of them can reach 300 feet down to bedrock). Last month, the NASA and the National Snow and Ice Data Center announced Arctic and Antarctic sea ice reached its lowest point ever in 38 years.
Sinking a US carrier — Sinking an aircraft carrier is difficult, but not impossible. The key is what it’s used for, and who it’s used against. But if you wanted to sink one, here’s what you’d have to do, and what you’d be up against.
Meme armies turning into militias — As political discourse in the US has become more polarized and contentious, so too has its symbology. Pepe the Frog and Expendables posters have given way to images of actual violence that political extremists spread and celebrate: 4chan, trading on a popular videogame meme, refers to Damigo as ‘The Falcon Punch at Berkeley.’ Much of it resembles military propaganda. The meme warriors, it seems, have become a militia.
The urgent power of remembering the holocaust in VR — Pinchas Gutter has returned to Majdanek at least a dozen times, but this trip is his final one to the onetime Nazi concentration camp. His first was one he was 11, when he was taken to Majdanek; now he’s 85 years old, and this is the last time he’ll come here to tell people what the Nazis did to his family. As he rides up to the shuttered camp in the backseat of a chauffeured sedan, he talks about why he’s told his story so many times. His trip to Majdanek, and the horrific experiences he recounts in the camp’s barracks and crematorium, are being preserved with virtual reality thanks to the USC Shoah Foundation.
Olympian f__kwit declares dystopian states like North Korea are the best at avoiding obesity … yes, thanks to mass starvation — James Cracknell is a British athlete and two-time gold medal Olympian. But now he has his sights set on politics. His pet issue? Tackling obesity. But wait until you hear what he believes are model countries for battling the obesity epidemic. [God help us.]
