The Alcubierre drive ([alkuˈβjere]) is a speculative warp drive idea according to which a spacecraft could achieve apparent faster-than-light travel by contracting space in front of it and expanding space behind it, under the assumption that a configurable energy-density field lower than that of vacuum (that is, negative mass) could be created.
Miguel Alcubierre theorized that it would be possible to create a warp drive, in which a ship would be enclosed in a "warp bubble" where the space at the front of the bubble is rapidly contracting and the space at the back is rapidly expanding, with the result that the bubble can reach a distant destination much faster than a light beam moving ...
Warp drive, or a drive enabling space warp, is one of several ways of travelling through space found in science fiction. [3] It has been often discussed as being conceptually similar to hyperspace. [3] [4]: 238–239 A warp drive is a device that distorts the shape of the space-time continuum.
A revolutionary study introduces a warp drive model compatible with known physics, offering a scientifically grounded approach to faster-than-light travel.
The idea of a warp drive is particularly appealing because it’s technically describable within general relativity, as the Mexican theoretical physicist Miguel Alcubierre proposed back in 1994.
In 2012, NASA reported that it was experimenting with the concept of warp drive and the loophole within Einstein's theory of relativity. [ clarification needed ] By 2014, it was announced that designer Mark Rademaker had created a CGI representation of a new vessel that would achieve warp velocity.
If (i.e. when velocity of jet is close to the velocity of light) then > despite the fact that <. And of course β T > 1 {\displaystyle \beta _{\text{T}}>1} means that the apparent transverse velocity along C B {\displaystyle CB} , the only velocity on the sky that can be measured, is larger than the velocity of light in vacuum, i.e. the motion ...
A Krasnikov tube [1] is a speculative mechanism for space travel involving the warping of spacetime into permanent superluminal tunnels. The resulting structure is analogous to a wormhole or an immobile Alcubierre drive (and like them requires exotic matter with negative energy density) with the endpoints displaced in time as well as space.
