Math geeks at University of Rochester say it's theoretically possible to create a wormhole between two locations. The beauty part is that you'd be invisible while you travel between them. The tech you'd use to do this sounds a little like Philip K. Dick's "scramble suit" from A Scanner Darkly. "Metamaterials" that bend electromagnetic fields would create a space from which light couldn't escape, thus making you effectively invisible as you "tunneled" to another spot. When are they going to start selling this at Radio Shack?
