An alternate timeline is a reality which is different from a parallel universe in that historical events have been altered by a time traveller. These alterations are usually prevented from having ever come to pass, although memories of them are usually retained.

An alternate timeline is a parallel universe that has been created by altering one or more events in one's subjective past, usually unintentionally.

22nd Century Alternate Timelines

In 2152, Captain Jonathan Archer's removal from history by Daniels created a timeline in which Earth of the 29th century was devastated. (ENT episode: "Shockwave")

In 2153, the Enterprise crossed over into a timeline in which the Daedalus had not been destroyed. (ENT novels: Daedalus and Daedalus's Children)

Later that year, a timeline was created in which Archer was rendered unfit for command, leading to the destruction of Earth by the Xindi and the near extinction of humanity. (ENT episode: "Twilight")

In 2154, a timeline was created in which an attempt by the Enterprise to enter a subspace corridor sent it over a century into the past. (ENT episode: "")

Later that year, the Enterprise encountered a timeline in which the Na'kuhl had aided Nazi Germany in World War II. (ENT episodes: "Zero Hour" and "Storm Front")

23rd Century Alternate Timelines

An alternate timeline was created in 2233 when Nero and Spock traveled back in time from 2387. (TOS movie: Star Trek)

In 2254, Yeoman J. Mia Colt traveled to an alternate 2293 in which James T. Kirk commanded the Bounty. (EV comic: "Future Tense")

In 2266, a timeline was created in which Kirk died on Grex in 2247. (TOS trilogy: The Janus Gate)

In 2267, Doctor Leonard McCoy traveled through the Guardian of Forever to 1930, creating a timeline in which Edith Keeler did not die in a traffic accident. (TOS episode: "The City on the Edge of Forever" and TOS novel: Provenance of Shadows)

In one timeline, Kirk and Spock failed to prevent McCoy from saving Keeler. (TOS short story: "Triptych")

In another, Keeler was brought to the 23rd century, thus preserving history while allowing her to live. (short story: "Remembering the Future")

Later that year, the Enterprise made first contact with the Mirror Universe. (TOS episode: "Mirror, Mirror")

See Mirror Universe article for other crossovers with the main Mirror Universe and alternate Mirror Universes.

In 2268, the Enterprise crew made first contact with the X-Men, a group of mutated humans from another timeline. (TOS comic: Star TreX)

Later that year, the Clan Ru created a timeline in which dinosaurs never became extinct and humans never evolved. (TOS novel: First Frontier)

In one timeline, in 2269 Kirk was abducted by Kor, subjected to a Klingon mind sifter, and transported through the Guardian of Forever to 1950s Earth. (TOS short story: "Mind-Sifter")

Also that year, the Romulans implemented their Second History project, briefly creating a timeline in which the Federation never existed. (TOS novel: Killing Time)

Towards the end of the year, a timeline was created in which Spock died on Vulcan as a child. (TAS episode: "Yesteryear")

In 2270, Dr. Georges Mordreaux conducted time travel experiments that resulted in alternate timelines, including one in which his insane future self killed Kirk with a spiderweb gun. (TOS novel: The Entropy Effect)

History

An alternate timeline is an iteration of a single reality in which events happen differently than they normally would've. Alternate timelines occur most frequently due to tampering with the Timestream, but have been shown to sometimes occur naturally. They may either completely replace, or coexist with the regular timeline.

Flash-sideways Timeline
(Oceanic Flight 815 lands at LAX)
This article has been nominated for renaming.
It has been suggested that this article be renamed to Parallel timeline or Alternate timeline - Discuss

This image displays the time loop and the alternate timeline created at the time of Jughead's detonation. Both exist at the same time.
A flash-sideways timeline, in which the Island was submerged in the ocean and Oceanic Flight 815 never crashed there, was a direct result of the reset, as hypothesized by Daniel Faraday. The creation of this timeline did not interfere with the timeline from which it was created, and with which it had many differences.

Events of the flash-sideways timeline, 2004

On the plane

The statue submerged ("LA X, Parts 1 & 2")

In the flash-sideways timeline, the Island was submerged under the ocean. As a result, Desmond Hume never crashed on the Island, and therefore was never there to stop pressing the button in the Swan station, keeping Oceanic Flight 815 from ever crashing.

The passengers of Flight 815 had slight changes in their past from the timeline that had been previously shown on the show. Boone was unsuccessful in persuading Shannon to return to Los Angeles with him. Hurley, though still a winner of the lottery, was not afflicted with the bad luck The Numbers brought him. Charlie's hair was noticeably shorter.

As Flight 815 passed over the Island, flight attendant Cindy Chandler offered Jack Shephard one drink (as opposed to the two she offered him in the crash timeline). Jack expressed anxiety as the plane encountered some turbulence, but Rose Nadler comforted him until the turbulence passed. Rose's husband Bernard returned from the restroom in the tail section, commenting on how the turbulence had nearly killed him. Jack himself got up to go to the restroom, where he found a strange hematoma on his collarbone that he had obviously not seen before. Dabbing it with a napkin, he returned to his seat.

To his surprise, Desmond Hume was sitting in the seat beside his. Jack seemed to recognize Desmond, though only vaguely, and Desmond did not recognize him. Desmond complained of a snoring seatmate further back on the plane, which prompted him to move seats.

Meanwhile, John Locke introduced himself to Boone Carlyle, and the two began discussing their reasons for being on the plane. Locke told a skeptical Boone of a walkabout experience that he allegedly was a part of. Boone was intrigued, and the two continued to talk.

Cindy Chandler then paged for any passengers who were doctors, to which Jack responded. He was then taken to the front of the plane, where a passenger had apparently fallen unconscious in a locked bathroom. After Sayid kicked the door open, it was revealed that Charlie Pace was inside, unconscious and unable to breathe. The flight attendants get Jack Shepard to help him, and he is able to resuscitate him, removing a bag of heroin clogged in Charlie's throat. When Charlie is arrested in Los Angeles as the plane landed, the police escort Charlie off the plane. Charlie's checked luggage includes his guitar, which, in the original timeline, was not allowed to be checked onto the plane.

At LAX

Oceanic Airlines Flight 815 lands in Los Angeles with all passengers alive. At Customs, Jack Shepard is told by a staff member that his father's body didn't arrive, and the staff in fact do not know where it is. While waiting at the airport Lost and Found and calling his mother to postpone the funeral, which was to be two hours after he landed. he meets John Locke, who is bound in a wheelchair and is missing a case full of knives. When Jack asks him about what happened (referencing Locke's paralysis), Locke simply replies that he has a condition that was irreversible. Before Locke leaves, Jack gives him his card, saying nothing is irreversible and willing to consult Locke anytime, free of charge.

While their bags are being inspected in Customs, Jin-Soo Kwon is questioned about what business he is in. Not understanding english, "No english", he hands a letter to the customs personnel, but the letter only explains that the watch he is carrying is a business gift but does not answer what the agent wanted to know. In Korean Jin asks if they can "continue on their way" but the agent searches his suitcase and finds a bag of money, the purpose of which is unknown. He is then taken into custody, not being able to account for the money that was not declared in his baggage. Sun appears not to know about the money or speak English, although she may be lying. Sun-Hwa Kwon is being called by her maiden name, Ms. Paik, which may mean the two are not married.

Kate Austen gets Edward Mars to bring her to the female restroom. In the stalls, Kate unlocks her cuffs, knocking out her escort and taking his weapon before escaping. Kate gets aboard an elevator, able to avoid security guards inside the elevator with the help of James "Sawyer" Ford. After getting out, she goes through a code activated staff door and escapes to a taxi stop. While waiting for a taxi just behind Hurley, Edward Mars spots her and she hijacks a taxi, holding the driver gunpoint, with Claire Littleton onboard.

An alternate timeline is a tangential space-time continuum, typically created upon the alteration of one or more events in the "past". Alternate timelines are frequently the result of unintentional temporal interference. There are many types of alternate timelines, but most of those observed fit into two main categories, "closed" and "open".

Contents

Closed timelines

Closed timelines occur when an alternate timeline is created then eliminated through actions of "external" agents. Typically, the participants within these timelines are unaware of any change, either upon the creation of the alternate timeline, or once the timeline reverts to its "true" form, unless shielded from those changes by temporally sensitive materials (see chronitons, temporal shields). Since this is the case, most incidents of closed timelines go unreported, except by the Department of Temporal Investigations. Such timelines usually involve a cyclic aspect (action in the original timeline altering the past/future, creating an alternate timeline, an object/person unaffected by the temporal change travelling to/already present in the past/future to ensure the original timeline is re-established).

Open timelines

An open timeline is better described as a parallel universe. As a result of quantum determinism, every event that can occur, will occur in alternate universes. (TNG: "Parallels") These alternate timelines differ from closed timelines as the events continue to influence the timeline they altered, without "external" interference. The mirror universe is an example of such an alternate timeline, which has become a primary focus for Federation scientists.

Many fans believe Star Trek: Enterprise takes place in such a timeline, effected either by the Temporal Cold War or events of Star Trek: First Contact. This seems unlikely, as Archer is heard referencing the trading post of Rigel X in a 24th century holoprogram in "These Are the Voyages..." (This involves the series premiere "Broken Bow", which introduced the Temporal Cold War). Some consider "These Are the Voyages..." to also be set in this alternate timeline, which would explain inconsistencies compared to the events of TNG: "The Pegasus".
