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.
Unknown: Cosmic Time Machine is an episode of the four-episode 2023 Netflix documentary series Unknown, about NASA's development and launch of the James Webb Space Telescope. [1] The episode follows the development of the telescope from the 1990s through its 2021 launch and 2022 deployment, and the unveiling of some of the first images from the ...
A Krasnikov tube [1] is a speculative mechanism for space travel involving the warping of spacetime into permanent superluminal tunnels. The resulting structure is analogous to a wormhole or an immobile Alcubierre drive (and like them requires exotic matter with negative energy density) with the endpoints displaced in time as well as space.

In 2015, Geek.com recommended this episode as "essential watching" for their abbreviated Star Trek: Deep Space Nine binge-watching guide. [3] In 2016, The Hollywood Reporter rated "A Time to Stand" with the first six episodes of the season, collectively the 38th best episode of all Star Trek television episodes. [4]
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.

Solar-electric propulsion record, including a velocity change in space of 25,700 mph (11.49 km/s). This is 2.7 times the velocity change by solar-electric ion drive than the past record. Achieved 5.9 years of ion engine runtime by September 7, 2018. This amount of runtime equates to 54% of Dawn's time in outer space.
