First Black Hole For Light Created On Earth

An anonymous reader writes "An electromagnetic 'black hole' that sucks in surrounding light has been built for the first time. The device, which works at microwave frequencies, may soon be extended to trap visible light, leading to an entirely new way of harvesting solar energy to generate electricity. A theoretical design for a table-top black hole to trap light was proposed in a paper published earlier this year by Evgenii Narimanov and Alexander Kildishev of Purdue University in West Lafayette, Indiana. Their idea was to mimic the properties of a cosmological black hole, whose intense gravity bends the surrounding space-time, causing any nearby matter or radiation to follow the warped space-time and spiral inwards."

Seriously man (or whatever), get a life.

Clearly by saying "light (electromagnetic radiation)", where he should have just said "microwave radiation", he was being unclear.

This device doesn't work with xrays, gamma rays, infrared, ultraviolet, or any other stuff ("light", whatever) except some of the microwave segment of the electromagnetic spectrum. I'd say that on a site devoted to technical news, it's sloppy to use "light" as a generic term for electromagnetic radiation, and also sloppy to substitute either of the above for microwaves.

you were being a douche

Fine. Whatever. I'm a douche for correcting someone else's ambiguous post. Now you're a douche for calling me a douche.
