LETTER TO THE EDITOR: The warp drive: hyper-fast travel within general relativity

  title={LETTER TO THE EDITOR: The warp drive: hyper-fast travel within general relativity},
  author={Miguel Alcubierre},
It is shown how, within the framework of general relativity and without the introduction of wormholes, it is possible to modify a spacetime in a way that allows a spaceship to travel with an arbitrarily large speed. By a purely local expansion of spacetime behind the spaceship and an opposite contraction in front of it, motion faster than the speed of light as seen by observers outside the disturbed region is possible. The resulting distortion is reminiscent of the \warp drive" of science ction…

Warp Drive: A New Approach
Certain classes of higher dimensional models suggest that the Casimir effect is a candidate for the cosmological constant. In this paper we demonstrate that a sufficiently advanced civilization
Do not mess with time: Probing faster than light travel and chronology protection with superluminal warp drives
While General Relativity ranks undoubtedly among the best physics theories ever developed, it is also among those with the most striking implications. In particular, General Relativity admits
Warp Drive Basics
“Warp drive” spacetimes and wormhole geometries are useful as “gedanken-experiments” that force us to confront the foundations of general relativity, and among other issues, to precisely formulate
Hyper-fast interstellar travel via a modification of spacetime geometry
We analyze difficulties with proposals for hyper-fast interstellar travel via modifying the spacetime geometry, using as illustrations the Alcubierre warp drive and the Krasnikov tube. As it is easy
The Possibility of FTL Space Travel by using the Quantum Tunneling Effect through the Light Barrier
In normal physics, nothing can move faster than the speed of light, because Einstein's theory of relativity forbids it. However, some physicists have proposed a model of faster-than-light (FTL)
Engineering the Quantum Foam
In 1990 Alcubierre, within the General Relativity model for space-time, proposed a scenario for `warp drive' faster than light travel, in which objects would achieve such speeds by actually being
Alcubierre's warp drive: Problems and prospects
Alcubierre’s warp drive geometry seemingly represents the ultimate dream for interstellar travel: there is no speed limit, the passengers are weightless whatever the acceleration, and there is no
So you want to stop time
A model of a stasis chamber, slowing the passage of time in its interior down to arbitrarily small rates relative to the outside world, is considered within classical general relativity. Since the
An Assessment of Faster-Than-Light Spacetimes: Make or Break Issues
*Implementation of faster-than-light (FTL) interstellar travel via traversable wormholes, warp drives, or other spacetime modification schemes generally requires the engineering of spacetime into
Detailed study of null and timelike geodesics in the Alcubierre warp spacetime
The geodesic equation of the Alcubierre warp spacetime is converted into its non-affinely parametrized form for a detailed discussion of the motion of particles and the visual effects as observed by
