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… Expand

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 civilizationExpand
Probing Faster than Light Travel and Chronology Protection with Superluminal Warp Drives
Faster than light travel and time machines are among the most tantalising possibilities allowed for by Einstein’s general relativity. In this chapter we shall review the main features of theseExpand
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 formulateExpand
LETTER TO THE EDITOR: Quantum effects in the Alcubierre warp-drive spacetime
The expectation value of the stress - energy tensor of a free conformally invariant scalar field is computed in a two-dimensional reduction of the Alcubierre `warp-drive' spacetime. Unless theExpand
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 easyExpand
Nadsvětelný pohyb v obecné relativitě
We show how superluminal travel can be achieved by means of the Alcubierre warp drive. In this spacetime a spaceship locally at rest is surrounded by a „bubble“ moving faster than the speed of light.Expand
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)Expand
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 beingExpand
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 noExpand
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 theExpand
