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.
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.
A new study published on the preprint server arXiv ponders whether it might be possible to detect the presence of warp engines at work among advanced alien civilizations. Scientists from the U.K ...
A revolutionary study introduces a warp drive model compatible with known physics, offering a scientifically grounded approach to faster-than-light travel.
[citation needed] One such distortion is the Alcubierre drive, which can be thought of as producing a ripple in spacetime that carries an object along with it. Another possible system is the wormhole, which connects two distant locations as though by a shortcut. Both distortions would need to create a very strong curvature in a highly localized ...
A theoretical principle for a faster-than-light (FTL) warp drive for spaceships has been suggested, using negative energy. The Alcubierre drive is based on a solution to the Einstein field equations of general relativity in which a "bubble" of spacetime is constructed using a hypothetical negative energy. The bubble is then moved by expanding ...
Certain kinds of hypothetical spacetimes called warp drives, which in a sense can be said to admit a kind of faster-than-light inertia-less and time-dilation-less travel, have been studied by some theoretical physicists since about 1990. This category contains articles related to such theoretical speculations.
