Researchers Create Portable Black Hole
Mini-hole made of metamaterials ensnares microwave light
“Physicists have created a black hole for light that can fit in your coat pocket. Their device, which measures just 22 centimetres across, can suck up microwave light and convert it into heat. The hole is the latest clever device to use ‘metamaterials’, specially engineered materials that can bend light in unusual ways. The new meta-black hole also bends light, but in a very different way. Rather than relying on gravity, the black hole uses a series of metallic ‘resonators’ arranged in 60 concentric circles. The resonators affect the electric and magnetic fields of a passing light wave, causing it to bend towards the centre of the hole. It spirals closer and closer to the black hole’s ‘core’ until it reaches the 20 innermost layers. Those layers are made of another set of resonators that convert light into heat. The result: what goes in cannot come out. “The light into the core is totally absorbed,” Cui says.”


Artificial Event Horizons
Device mimics black hole event horizon
“Now it seems these horizons can be mimicked using a table-top device that harnesses lasers to create an artificial black hole, according to a study by Prof Ulf Leonhardt of the University of St Andrews that could help win a Nobel prize for the world’s best known physicist, Prof Stephen Hawking. At St Andrews, Prof Leonhardt works on what are called quantum catastrophes, where so-called “singularities” can be created where the laws of wave physics are in danger of breaking down. Black holes are also singularities, where the pull of gravity is so intense that even light is sucked in. The professor’s team accomplished the feat of simulating key features of a black hole by firing lasers down an optical fibre, exploiting how different wavelengths of light move at different speeds within the fibre. Prof Hawking’s chance of winning the Nobel prize has improved markedly because this device makes it possible to test his theories, which make specific predictions about the event horizon – the rim of a black hole. “We show by theoretical calculations that such a system is capable of probing the quantum effects of horizons, in particular Hawking radiation.”

Blackest Body Yet
Scientists Make Blackest Material Ever
“Scientists have fashioned what may be the blackest material in the universe: a sheet of carbon nanotubes that captures nearly every last photon of every wavelength of light. The substance absorbs between 97 percent and 99 percent of wavelengths that can be directly measured or extrapolated. It’s the closest that scientists have yet come to a black body, a theorized state of perfect absorption whose closest analogue is believed to be the opening of a deep hole. The material is made from a flat array of vertically-aligned, single-walled carbon nanotubes. Photons that aren’t immediately absorbed by a single nanotube deflect off and are absorbed by its neighbors. “This interaction,” write the researchers, “repeats until the attenuated light is completely absorbed by the forest.” To the naked eye, the substance appears perfectly flat; in effect, it’s a sheet of deep holes. By comparison, the blackest paints and coatings absorb between 84 and 95 percent of all light. Researchers say the material would be useful in solar panels or to collect heat in the frigid vacuum of space.”

About Jay Babcock

I am the co-founder and editor of Arthur Magazine (2002-2008, 2012-13) and curator of the three Arthur music festival events (Arthurfest, ArthurBall, and Arthur Nights) (2005-6). Prior to that I was a district office staffer for Congressman Henry A. Waxman, a DJ at Silver Lake pirate radio station KBLT, a copy editor at Larry Flynt Publications, an editor at Mean magazine, and a freelance journalist contributing work to LAWeekly, Mojo, Los Angeles Times, Washington Post, Vibe, Rap Pages and many other print and online outlets. An extended piece I wrote on Fela Kuti was selected for the Da Capo Best Music Writing 2000 anthology. In 2006, I was one of five Angelenos listed in the Music section of Los Angeles Magazine's annual "Power" issue. In 2007-8, I produced a blog called "Nature Trumps," about the L.A. River. Today, I live a peaceful life in the rural wilderness of Joshua Tree, California, where I am a partner in JTHomesteader.com with Stephanie Smith.
