A staple plot device of science fiction stories is the "wormhole," a spatio-temporal anomaly which permits faster-than-light travel between two points by bridging the gap between themvia hyperspace or some supradimensional astral plane.

Apparently, they may not be entirely fictional. Elusive, mysterious, and transient, yes, but a NASA program is going to try to find what they call X-points or electron diffision regions which open up from time to time where the solar wind meets the Earth's magnetosphere.

The X-points aren't actually transdimensional rapid-transit systems, but they're certainly unusual.
