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.
These included the gravity-based pitch drive, bias drive, disjunction drive and diametric drive; the Alcubierre drive; and the vacuum energy based differential sail. [13] The project then considered the mechanisms behind these drives. At the end of the project, three mechanisms were identified as areas for future research.
Miguel Alcubierre Moya (born March 28, 1964) is a Mexican theoretical physicist. [4] Alcubierre is known for the proposed Alcubierre drive, a speculative warp drive by which a spacecraft could achieve faster-than-light travel.
White attracted the attention of the press when he began presenting his ideas at space conventions and publishing proposals for Alcubierre drive concepts. In 2011, he released a paper titled Warp Field Mechanics 101 that outlined an updated concept of Miguel Alcubierre's faster-than-light propulsion concept, including methods to prove the feasibility of the project.
In physics, the Alcubierre drive is based on an argument, within the framework of general relativity and without the introduction of wormholes, that it is possible to modify spacetime in a way that allows a spaceship to travel with an arbitrarily large speed by a local expansion of spacetime behind the spaceship and an opposite contraction in ...

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 ...
