Mathematicians Design Invisible Tunnel
New calculations show how to make an electromagnetic "wormhole" — a tube that is invisible from the sides but allows light to shine down the center. The practical applications are a ways off, as even the design of a spherical invisibility cloak has not advanced beyond working (in theory) for a single wavelength of visible light.
Ok... Let the penis-size jokes ensue!

Why don't we prove that instead?
