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 ...
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 ...
The Alcubierre drive uses exotic matter (not to be confused with antimatter) to travel faster than light. While the concept had been out since 2013 the design of IXS Enterprise was popularized in June 2014 after a series of media outlets reported on the conceptual artwork done by Dutch artist Mark Rademaker in collaboration with NASA.

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.
Priscilla Weaver packed for her six-hour drive to Phoenix bringing along her U.S. passport and other forms ofidentification, including one showing she's a Navajo Nation citizen.
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.
Cross-section diagram of a pulsed inductive thruster. [1] The gas is puffed inward through a central nozzle, towards the flat electromagnetic coil where it is ionized. [2] The plasma (pink) is then accelerated to the rear by the Lorentz force. A pulsed inductive thruster (PIT) is a form of ion thruster, used in spacecraft propulsion.
