Krasnikov tube : ウィキペディア英語版 | Krasnikov tube
A Krasnikov tube is a speculative mechanism for space travel involving the warping of spacetime into permanent superluminal tunnels. The resulting structure is analogous to a wormhole with the endpoints displaced in time as well as space. The idea was proposed by Serguei Krasnikov in 1995. ==Structure== The tube is a distortion of spacetime that can be intentionally created (using hypothetical technology) in the wake of travel near the speed of light. The Krasnikov tube allows for a return trip that takes you back to the time right after you left. This several light-year long artificial "tube" might arguably constitute a megastructure, but unlike most megastructures it's not constructed of physical matter such as titanium or plastic, but instead is just a distortion of spacetime. Experiencing the effect requires that the traveler race along the tube at speeds close to that of light.
