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.
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 warp nacelles generate a subspace field, the warp field or a warp bubble, which distort space-time and propels the bubble and spaceship in the bubble forward. That is similar to the Alcubierre drive , but with some exceptions as the maintenance of sub-light velocity and inertia.
In physics, spacetime, also called the space-time continuum, is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams are useful in visualizing and understanding relativistic effects, such as how different observers perceive where and when events ...
Time travel in modern fiction is sometimes achieved by space and time warps, stemming from the scientific theory of general relativity. [9] Stories from antiquity often featured time travel into the future through a time slip brought on by traveling or sleeping, in other cases, time travel into the past through supernatural means, for example brought on by angels or spirits.
The IXS Enterprise as imagined by Mark Rademaker. IXS Enterprise is a conceptual interstellar superluminal spacecraft designed by NASA scientist Dr. Harold G. White, revealed at SpaceVision 2013, designed for the goal of achieving warp travel.
Artist rendition of a spaceship entering warp drive. Generic terms for engines enabling science fiction spacecraft propulsion include "space drive" and "star drive". [g] [2]: 198, 216 In 1977 The Visual Encyclopedia of Science Fiction listed the following means of space travel: anti-gravity, [h] atomic (nuclear), bloater, [i] cannon one-shot, [j] Dean drive, [k] faster-than-light (FTL ...
Time dilation by the Lorentz factor was predicted by several authors at the turn of the 20th century. [3] [4] Joseph Larmor (1897) wrote that, at least for those orbiting a nucleus, individual electrons describe corresponding parts of their orbits in times shorter for the [rest] system in the ratio: .
