We not only have the Harry Potter Invisibility Cloak, but now we have a Stargate too.

New calculations show how to make an electromagnetic “wormhole” —a tube that is invisible from the sides, allowing light to shine down the center unseen.

The concept is a twist on a spherical cloak of invisibility proposed last year. Such a device would be made of metamaterial, a thicket of metal rings or other shapes that bends light in funny ways. A hollow shell of metamaterial could in principle channel light around its inner space without slowing the light down, rendering that hidey-hole invisible to the outside world.

Yeah, I know it doesn’t actually go anywhere. Yet.
