High Quality Content by WIKIPEDIA articles! The Cardiff Rift is a fictional wormhole in the science fiction television series Doctor Who and Torchwood, one end of which is located in Cardiff Bay, Wales. The other end is apparently floating freely through spacetime, and matter and radiation can pass through the Rift, allowing extraterrestrial and extratemporal artifacts, and occasionally life-forms, to "wash up" in Cardiff. It is described as "Unpredictable and elusive, it’s a gateway for alien creatures, alien weapons, all manner of alien technology and time anomalies to enter our world" and the "flotsam and jetsam of the universe since the dawn of time."
