Light can't escape a black hole. Some people look at this fact and get the shudders. Others think, "Hey, that would make a really effective solar panel!"
Or, rather, it might if not for that whole "massive, crushing force of gravity" problem. MIT's Technology Review has a neat piece about scientists trying get around that minor hiccup. They're working with light-distorting metamaterials, the stuff you frequently see written up in stories about the coming of futuristic cloaking devices, alongside references to Harry Potter's invisibility cloak. But instead of bending light around the metamaterial, these researchers are focusing on a weirder--and, in my opinion, much cooler--goal.
...a metamaterial that distorts space so severely that light entering it (in this case microwaves) cannot escape.Their black hole consists of 60 layers of printed circuit board arranged in concentric circles (see picture below). The printed circuit boards are coated in a thin layer of copper from which Qiang and Tie have etched two types of pattern that either resonate at microwave frequency or do not. They've measured microwaves at 18 GHz going in and none coming out. And the circular symmetry of their metamaterial means that the microwaves are absorbed in all directions at once.
There you have it: The light-capturing power of a black hole, without the teeny inconvenience of being smooshed. Incorporate the material in solar collectors, and you could end up with a much more efficient way of harnessing the sun for energy.
Princeton University psych prof Susan Fiske published an open letter denouncing the practice of using social media to call out statistical errors in psychology research, describing the people who do this as “terrorists” and arguing that this was toxic because of the structure of social science scholarship, having an outsized effect on careers.

Today, I’ve launched a very special Kickstarter with two friends, Timothy Daly and Lawrence Azerrad. A year in the making (and many more years on our minds), the Voyager Golden Record: 40th Anniversary Edition is the first vinyl release of the stunning golden phonograph record launched by NASA in 1977 aboard the Voyager spacecraft, one […]
If you own a dog, you’ve most likely heard of BarkBox – the monthly subscription box for dogs. What started as a simple idea to try out the subscription model on pet owners has since developed a cult following of dog lovers. If you haven’t given it a try yet, this one month free deal is the […]
With the iPhone headphone jack having gone by the wayside, we’re excited about the addition of the FRANKLIN Bluetooth Headphones in our store. These headphones are foldable so they’re easy to carry around, but most importantly, they pack impressive sound. Our biggest struggle with Bluetooth headphones is the worry of them dying at the worst moment. This pair lasts an impressive 8-10 […]
