==Subspace==
In the ''[[Star Trek]]'' fictional universe, '''subspace''' is a feature of [[Spacetime|space-time]] that facilitates [[faster-than-light]] transit, in the form of interstellar travel or the transmission of information.<ref>{{cite web | title = StarTrek.com Official StarTrek Website, Subspace Radio Article | url = http://www.startrek.com/startrek/view/library/technology/article/70261.html | access-date = 2007-10-22 | archive-date = July 16, 2009 | archive-url = https://web.archive.org/web/20090716034335/http://www.startrek.com/startrek/view/library/technology/article/70261.html | url-status = live }}</ref> Faster-than-light [[Warp drive (Star Trek)|warp drive]] travel via subspace obeys different laws of physics. The name "subspace" has also been adopted and used in other fictional settings, such as the ''[[Stargate]]'' franchise, ''[[The Hitchhiker's Guide to the Galaxy]]'' series, the ''[[Bobiverse]]'' series, and ''[[Descent: Freespace]]''. Narratively, it plays a similar role to the [[hyperspace]] that appears in ''[[Star Wars]]'' and other works of science fiction.

In most ''Star Trek'' series, subspace communications are a means to establish nearly instantaneous contact with people who are [[light year]]s away. The physics of ''Star Trek'' describes infinite speed (expressed as "warp factor 10") as an impossibility; as such, even subspace communications which travel at speeds over Warp 9.9 may take hours or weeks to reach certain destinations. One exception to this impossibility was in the ''[[Star Trek: Voyager]]'' episode "[[Threshold (Star Trek: Voyager)|Threshold]]" where Lt. Paris breaks the Warp 10 barrier. In the ''Star Trek'' universe subspace signals do not degrade with the square of the distance as do other methods of communication utilizing conventional bands of the electromagnetic spectrum (i.e. radio waves), so signals sent from a great distance can be expected to reach their destination at a predictable time and with little relative degradation (barring any random subspace interference or spatial anomalies).{{citation needed|date=September 2020}}

In the ''Star Trek'' franchise, subspace communications have a limit of just over 20 [[Light-year|light years]] before they must be boosted,<ref>{{Cite book |url=https://archive.org/details/TNGTechManual |title=TNG Tech Manual}}</ref> although this limitation has been ignored in several storylines.{{citation needed|date=September 2020}}
