Hunting for Tunnels in Space-Time

You've probably seen it on television or in film, or read it in a fictional story: characters find a wormhole and use it to travel backwards or forwards through space or even time. Some scientists believe there might be an element of truth to that.

According to physicist Eric Davis, "A traversable wormhole is a hyperspace tunnel, also called a throat, that connects together two remotely distant regions within our universe, or two different universes — if other universes exist — or two different periods in time, as in time travel, or different dimensions of space."

Davis is trying to use Einstein's general theory of relativity to design traversable wormholes, warp drives, and even time machines. This might be difficult: no one has ever seen a wormhole, and based on current theories it is unlikely that an open wormhole would stay open long enough for a person to traverse it.

But according to one scientist, dark matter may hold the key to one day finding …
