'''Temporal mechanics''' is the study of the workings of [[time]] and its effects on the [[space-time continuum]], and is particularly relevant when dealing with time travel. As late as [[2154]], time travel was deemed impossible by the [[Vulcan Science Directorate]]. ({{ENT|Awakening}})

The [[United Federation of Planets]] has had some form of time travel ability since at least [[2268]]. It is possible that at least some of the current and future regulations regarding time travel can trace their origins back to this date. However, capability at this point was most likely inaccurate, making any attempt at time travel experimental and dangerous.

Temporal mechanics is taught at [[Starfleet Academy]]. [[Julian Bashir]] took the class, where he learned about [[predestination paradox]]es, as did [[Miles O'Brien]]. ({{DS9|Trials and Tribble-ations}}) Both [[Kathryn Janeway]] and [[B'Elanna Torres]] knew the 'finer points' of temporal mechanics. ({{VOY|Parallax}})

In [[2267]], after an encounter with a [[black star]], the ''Enterprise'' was hurled 300 years into the past. Eventually, the ''Enterprise'''s science officer [[Spock]] devised a method for returning the ''Enterprise'' back to its original period. ({{TOS|Tomorrow is Yesterday}})

Though other instances of time travel had been noted, this appears to be the first instance of controlled time travel by the [[United Federation of Planets|Federation]]. Later that year, officers [[James T. Kirk|Kirk]], [[Spock]] and [[Leonard McCoy|McCoy]] traveled to [[Earth]]'s early [[20th century]] and back via the [[Guardian of Forever]].

Sometime in [[2268]] the ''Enterprise'' traveled back in time, using the [[light-speed breakaway factor]], to [[1968]] on a historical research mission. ({{TOS|Assignment: Earth}})
  
  +
[[Category:Episodes]]
−  
−
:''The existence of such a mission suggests that at least in 2268 the Federation was capable of controlled time travel and they used this ability at the very least for research purposes.''
  
−  
−
In [[2286]], [[Admiral]] James T. Kirk and his senior staff took a stolen [[Klingon Bird-of-Prey]] back in time to the year [[1986]] to retrieve a pair of then (2286)-extinct [[humpback whale]]s to save Earth from destruction by an alien probe. ({{film|4}})
  
−  
−
In [[2371]], Captains [[Jean-Luc Picard]] and James T. Kirk use the [[Nexus]] as a means of controlled time travel, going to just before the destruction of the [[Veridian]] star, which Picard intended to save. (Picard arrived at the Nexus from just after the destruction of said star, whereas Kirk arrived from some 78 years before. ({{film|7}})
  
−  
−
At least once, [[Q]] took Captain Jean-Luc Picard back in time to the beginning of life on [[Earth]]. It is unknown if Q actually willed himself and Picard to the beginning of life on earth or if it was just an illusion. ({{TNG|All Good Things...}})
  
−  
−
[[Quinn]] took {{USS|Voyager}} back in time to the [[Big Bang]] to hide from [[Q]]. ({{VOY|Death Wish}})
  
−  
−
In the [[25th century]], time travel is mostly possible but risky. ({{TNG|Firstborn}})
  
−  
−
In [[2373]] the [[USS Defiant|USS ''Defiant'']], commanded by [[Captain]] [[Benjamin Sisko]] traveled back in time to [[2268]] via the [[Bajoran]] [[Orb of Time]], by an attempt by [[Arne Darvin]] to kill Captain James T. Kirk and change the timeline. The crew of the ''Defiant'' stopped Darvin without any notable damage. ({{DS9|Trials and Tribble-ations}})
  
−  
−
Also in 2373, an encounter with the [[29th century]] [[timeship]] ''[[Aeon]]'' threw ''Voyager'' back to an alternate [[1996]]. History was set right when Captain Janeway destroyed the timeship before it could travel to the future and accidentally cause a [[temporal explosion]]. ''Voyager'' was returned to the correct time by an alternate version of the ''Aeon'' from the correct timeline. ({{VOY|Future's End|Future's End, Part II}})
  
−  
−
An alternate future version of Captain Janeway (from [[2404]]) traveled back to [[2378]] to bring ''Voyager'' home from the [[Delta Quadrant]] 16 years earlier then it had arrived in that alternate future. This future Janeway was killed in the attempt but succeeded in returning ''Voyager'' home and even delivered a crippling if not fatal blow to the [[Borg]]. ({{VOY|Endgame}})
  
−  
−
===Temporal Cold War===
  
−
The events of the [[Temporal Cold War]] further complicate the understanding of Federation time travel capabilities.
  
−  
−
As early as the [[26th century]], [[history|historians]] and [[anthropology|anthropologists]] used [[Time-travel pod]]s to travel through time to observe historical events. ({{TNG|A Matter of Time}}) [[Crewman]] [[Daniels (Crewman)|Daniels]], an alleged time traveler from the [[31st century]], showed [[Jonathan Archer]] a group of time-traveling anthropologists from [[2769]] observing the building of the [[pyramid]]s of [[Giza]]. ({{ENT|Cold Front}})
  
−  
−
As of the [[29th century]], a time traveling faction represented by a [[Future Guy|mysterious individual]], could only communicate and exchange information and technologies through time, appearing as a non-corporeal entities. By the [[31st century]], this technology was perfected to allow physical travel.
  
−  
−
According to Daniels, all time travelers were bound by the observance of strict procedures set forth in the [[Temporal Accords]]. Daniels stated that the Temporal Accords were enacted after time travel was developed by all time travel–capable species to prevent catastrophic tampering with the [[timeline]].
  
−  
−
By [[2153]], the [[Sphere Builder]]s, a group previously thought to possess the ability only to examine alternate timelines, sent [[Xindi-Reptilian]]s back to 21st century Detroit to develop a [[Xindi bioweapon|bioweapon]] to destroy the [[Human]] race. ({{ENT|Carpenter Street}})
  
−  
−
:''Because the Sphere Builders exist in a separate dimension, they may not have had any involvement in the creation of the Temporal Accords.''
  
−  
−
Ultimately the war ended when the [[Na'kuhl]] returned from an alternate [[1944]] (created by their very actions) and caused the Cold War to go hot with time-travelers changing time as they liked. Daniels brought ''Enterprise'' and Archer back to 1944 to stop [[Vosk]], leader of the Nak'uhl, from returning to the future. With the help of [[Silik]], a member of another faction of the Temporal Cold War, Archer shut off Vosk's compound's [[shields]], allowing ''Enterprise'' to destroy it and thus destroying the [[temporal conduit]] and killing Vosk just as he was about to travel back to the future. Daniels pulled Archer to a place where they watched the [[time stream]] as all of the events that occurred when the Temporal Cold War went hot were undone and time reset itself to normal. Archer refused to have anything to do anymore with Daniels' "damn Temporal Cold War" and Daniels agreed, claiming it was finally coming to an end thanks to Archer's actions.

In the [[novels|novel]] ''[[Ishmael (novel)|Ishmael]]'', Captain Spock embarked incognito aboard a Klingon ore transport, refitted with time travel capacity. The Ore transport managed to go back to Earth in 1867 after an acceleration close to a white dwarf near Starbase 12. The ''Enterprise'' was modified to follow the ship to 1867, becoming the first instance that a Federation ship utilized intentional and controlled time travel.

"Cause and Effect" 2278 2368 USS Bozeman with crew temporal rift
The USS Bozeman was trapped in a temporal causality loop since 2278. The USS Enterprise-D was trapped for only 17.4 days.
"Time's Arrow" 2368 1893 Two Unnamed Devidians and Data temporal distortion
1893 2368 Two Unnamed Devidians temporal distortion
2368 1893 Two Unnamed Devidians, Jean-Luc Picard, William T. Riker, Deanna Troi, Geordi La Forge, and Beverly Crusher temporal distortion
The two Devidians apparently made many trips before and perhaps during the episode to 1893 that were not shown, via temporal distortion.
"Time's Arrow, Part II" 1893 2368 the male Devidian, William T. Riker, Deanna Troi, Geordi La Forge, Beverly Crusher, Samuel Clemens, and Data's headless body temporal distortion
2368 1893 Samuel Clemens temporal distortion

2369 2327 Jean-Luc Picard's consciousness and Q Q powers
2327 2369 Jean-Luc Picard's consciousness and Q Q powers
It is possible that the time traveling in the episode was all an illusion by Q.
"Timescape" Time is slowed considerably before being reversed due to being trapped in a temporal fragment. Both the USS Enterprise-D and a Romulan warbird were trapped, and a runabout with Jean-Luc Picard, Deanna Troi, Geordi La Forge, and Data entered the fragment.
"Firstborn" ~2410 2370 Alexander Rozhenko unknown
2370 ~2410 Alexander Rozhenko unknown

2370 3.5 billion years ago Jean-Luc Picard and Q Q's power
3.5 billion years ago 2364 Jean-Luc Picard's consciousness Q's power
This time traveling in the episode may in fact be an illusion by Q. It is also unknown how many trips Picard made before he became aware of it (his memory was getting better with each trip).
