'''Time''' was a fundamental physical quality, measuring the duration of events and the intervals between them. It could be seen as part of the fundamental structure of the universe, a dimension in which events happened in sequence. [[Space-time vessel]]s, such as [[TARDIS]]es, could [[time travel|travel]] along this dimension in the same way that ordinary space vessels could travel along the other dimensions.


'''Time''' was the continuum/dimension in which one moment progresses to another and through which [[space-time vessel]]s [[time travel|traveled]]. The [[Web of Time]] governed order within this realm.
Having passed through the [[Time Vortex]] so often, [[the Doctor]], and those who travelled with him, developed a "special relationship" with time, making them more sensitive to its nuances. ([[TV]]: {{cs|City of Death (TV story)}})


==Explanations of time==
Time was naturally chaotic and "wild"; the [[Time Lord]]s forcibly held it in place on the planet [[Time (planet)|Time]] inside the [[Temple of Atropos]] by creatures known as the [[Mouri]]. ([[TV]]: {{cs|Once, Upon Time (TV story)}}) There existed a [[Time (mythology)|sentient, cosmic embodiment of the force of Time]], who had various avatars and with whom the Doctor had dealings across several incarnations, including as [[Time's Champion]]. ([[PROSE]]: {{cs|Human Nature (novel)}}, {{cs|Love and War (novel)}}; [[TV]]: {{cs|The Vanquishers (TV story)}})
Time has been described as a stream, ever flowing and ever changing. The Vortex had devestating effects on unprotected individuals, only [[Jack Harkness|one]] being is known to have survived exposure to the effects. A Tardis (or other time travel devices) allow one to safely traverse the stream, to go back and forth in time.
Time was one of the five dimensions described by [[Susan Foreman]] and from which she derived the name [[TARDIS]], which she came up with herself. ([[DW]]: ''[[An Unearthly Child]]'') While Susan described time as a dimension, [[the Master (UNIT years)|the Master]] (in the guise of "Professor Thascales") described time as made up of particles, known as [[chronon]]s. ([[DW]]: ''[[The Time Monster]]'') [[Tenth Doctor|The Doctor]] later laboured in an effort to explain how time is misunderstood and never strictly linear, that it is made up of "wibbly-wobbly, timey-wimey... stuff." ([[DW]]: ''[[Blink]]'')


A certain moment in time could be fixed, where something ''must'' happen, such as the volcanic eruption of Mount Vesuvius at Pompeii. ([[BFA]]: ''[[The Fires of Vulcan]]'', [[DW]]: ''[[The Fires of Pompeii]]'')
== Structure of time ==
When [[Clara Oswald]] asked what time was made of, the [[Eleventh Doctor]] assured her that it wasn't of [[Strawberry|strawberries]]. ([[TV]]: {{cs|The Rings of Akhaten (TV story)}})


It could also be in flux, allowing minor changes to history. Time isn't in a straight line but is more of a four-dimensional 'circle', and the location where TARDISes travel is the unexplained Time Vortex, which is also used to travel through space as well as time.
Instead, at a lower level, time was quantized, like a force, which {{Delgado}} (in the guise of "Professor Thascalos") described as made up of particles known as [[chronon]]s. ([[TV]]: {{cs|The Time Monster (TV story)}}) Chronons, like other particles, could be detected and interacted with. ([[GAME]]: {{cs|City of the Daleks (video game)}})


Though some events could be changed others were destined to happen, even when a Time Lord utilize his time travel technology to alter the stream certain events rearrange themself to the fixed line, as shown with [[Adelaide Brooke]] who commited suicide. Despite the doctor changing her supposed time of death events played out so that they came to pass, one way or another. ([[Waters of Mars]]) {{fact}}
While the [[Weeping Angel]]s were able to feed on the potential energy gained by displacing people into the past, ([[TV]]: {{cs|Blink (TV story)}}) even they could not feed on raw [[Time Field|time energy]]. Such energy, leaking out of cracks in the structure of the universe, absorbed an army of Angels at the crash of the ''[[Byzantium (spacecraft)|Byzantium]]'', completely removing them from history. ([[TV]]: {{cs|Flesh and Stone (TV story)}}) The Doctor suspected that the [[CyberKing]] walking over Victorian London and the [[Dalek]]s [[21st century Dalek invasion|invading]] Earth in [[Amy Pond]]'s era had been similarly erased, ([[TV]]: {{cs|Flesh and Stone (TV story)}}) and later saw [[Rory Williams]] absorbed by time energy. ([[TV]]: {{cs|Cold Blood (TV story)}}) [[Artron energy]] was also in some way connected with time, in a manner that was possibly too complicated for Time Lords to fully explain to humans. ([[TV]]: {{cs|Four to Doomsday (TV story)}}, {{cs|The Deadly Assassin (TV story)}})


Though some races have managed to travel through time (such as the [[Daleks]] and [[Time Agency]] of the [[51st century]]) only the[[Time Lords| Time Lords]] were the only species in the universe to have attained Mastery over Time in all it's aspects.
The structure of time had to be balanced or ordered in some way, a purpose of the [[Web of Time]]. ([[TV]]: {{cs|Attack of the Cybermen (TV story)}}) Additionally, time had a holistic structure like a balloon. If a mishap in time travel punched a hole in that structure, the universe could die in a matter of centuries. ([[TV]]: {{cs|The Two Doctors (TV story)}})

Allegedly, time was naturally chaotic and unreliable. During the [[Dark Times]], two creatures known as the [[Ravager (The Halloween Apocalypse)|Ravagers]], [[Old Swarm|Swarm]] and [[Azure (The Halloween Apocalypse)|Azure]], found pleasure in its chaotic nature. The only way to stabilise time was to assign creatures called [[Mouri]]. According to Swarm, it could be said that Time was at war with [[Space]]. ([[TV]]: {{cs|Once, Upon Time (TV story)}})
 
== Time travel ==
{{main|Time travel}}
New connections between different points in space-time could be created: for instance by [[time window]]s created by [[warp drive]]s; ([[TV]]: {{cs|The Girl in the Fireplace (TV story)}}) [[time storm]]s created by [[Fenric]]; ([[TV]]: {{cs|Dragonfire (TV story)}}, {{cs|Silver Nemesis (TV story)}}, {{cs|The Curse of Fenric (TV story)}}) or the [[crack]]s in the skin of the universe, which suddenly appeared at various times and places in the universe after a temporal explosion. ([[TV]]: {{cs|Flesh and Stone (TV story)}}, {{cs|The Vampires of Venice (TV story)}})
 
Furthermore, travel from any point to another was possible by passing through the [[Time Vortex]], by using a vehicle such as a [[TARDIS]] or [[Dalek time machine]] ([[TV]]: {{cs|The Chase (TV story)}}, et al.) or a device such as a [[vortex manipulator]], ([[TV]]: {{cs|Utopia (TV story)}}, {{cs|The Sound of Drums (TV story)}}, [[TV]]: {{cs|Everything Changes (TV story)}}, et al.) by creating a wormhole such as a [[time corridor]] ([[TV]]: {{cs|The Evil of the Daleks (TV story)}}, etc.), or even through direct psychic [[teleportation]]. ([[TV]]: {{cs|Planet of the Spiders (TV story)}})
 
Other races eventually learned to travel through time. These included the [[Dalek]]s ([[TV]]: {{cs|The Chase (TV story)}}) and [[human]]s. ([[TV]]: {{cs|Invasion of the Dinosaurs (TV story)}}) In the [[51st century]], humans established the [[Time Agency]]. ([[TV]]: {{cs|The Talons of Weng-Chiang (TV story)}}, {{cs|The Empty Child (TV story)}})
 
The [[Time Lord]]s, however, tried to keep strict controls on "unauthorised" use of time travel by other species. ([[TV]]: {{cs|The Time Warrior (TV story)}}, {{cs|The Two Doctors (TV story)}})
 
Uncontrolled time was extremely difficult to navigate around, meaning a person could set a destination and end up in a completely different location. It was also very harmful to time travel devices such as TARDISes. ([[TV]]: {{cs|The Halloween Apocalypse (TV story)}}, {{cs|War of the Sontarans (TV story)}}, {{cs|Once, Upon Time (TV story)}})
 
== Changing history ==
The [[Tenth Doctor]] laboured in an effort to explain to humans how time was misunderstood and never strictly linear, that it was "a big ball of wibbly-wobbly, timey-wimey... stuff." ([[TV]]: {{cs|Blink (TV story)}}) Another time, he tried making it easier for his companion, [[Martha Jones]], to understand by referencing ''[[Back to the Future]]'' to explain the mechanics of the "infinite temporal flux"; if the [[Carrionite]]s succeeded in freeing the rest of their kind and taking over [[Earth]], Martha would vanish as the future she came from would no longer exist. ([[TV]]: {{cs|The Shakespeare Code (TV story)}})
 
Travelling into the past allowed changing the future. As the [[Eleventh Doctor]] put it, "Time can shift. Time can change. Time can be rewritten." ([[TV]]: {{cs|Flesh and Stone (TV story)}})
 
However, erasing events from history did not always automatically change the future. Blocking chronons (e.g., with a TARDIS or a special-built device) could prevent objects from vanishing even though they no longer had a past. ([[GAME]]: {{cs|City of the Daleks (video game)}}) In a similar way, a [[paradox machine]] could be built (e.g., from a cannibalised TARDIS) to allow [[time paradox]]es to persist without effect. ([[TV]]: {{cs|The Sound of Drums (TV story)}}, {{cs|Last of the Time Lords (TV story)}}) Many individuals possessed [[history-proofing|the ability]] to remember the original version of history. ([[TV]]: {{cs|Flesh and Stone (TV story)}}, [[PROSE]]: {{cs|A Romantic Evening (short story)}}, [[AUDIO]]: {{cs|Seasons of Fear (audio story)|part=Four}}, etc.)
 
In a universe with time travel and a malleable space-time, there would be no fundamental [[stability|stable]] meta-structure to history. However, the Time Lords imposed one, which they called the [[Web of Time]], which connected the fragmentary nodes of history into a single whole. ([[AUDIO]]: {{cs|Neverland (audio story)}}) This Web required maintenance, as when the [[Sixth Doctor]] explained that the destruction of [[Earth]] in [[1985]] would disrupt the Web. ([[TV]]: {{cs|Attack of the Cybermen (TV story)}})
 
Even in the post-[[Gallifrey]] universe, some events were [[fixed point in time|fixed points]] which ''must'' happen. One example was the volcanic eruption of [[Mount Vesuvius]] at [[Pompeii]]. ([[AUDIO]]: {{cs|The Fires of Vulcan (audio story)}}, [[TV]]: {{cs|The Fires of Pompeii (TV story)}}) Changing fixed point events required highly advanced technology, and doing so could cause major damage to the continuum. ([[GAME]]: {{cs|City of the Daleks (video game)}})
 
Other moments were in flux, allowing minor changes to history. Some events even allowed dramatic changes in history, especially after the demise of the Time Lords in the [[Last Great Time War]]. ([[TV]]: {{cs|The Unquiet Dead (TV story)}}) An example of this occurred in [[2020]], when a drilling operation in [[Cwmtaff]] altered the future of the Earth by bringing humanity into contact with the [[Silurian]]s, which could have led to either a peaceful relationship or a devastating war. The Eleventh Doctor described these events as opportunities. ([[TV]]: {{cs|Cold Blood (TV story)}})
 
[[Time storm]]s could occur inside a person’s [[time stream]] if time was allowed to slip into its allegedly naturally chaotic state. If someone was to enter their own time streams during a time storm, bad things could happen to that person. ([[TV]]: {{cs|Once, Upon Time (TV story)}})
 
== Parallel universes and alternate timelines ==
At historical choice points, the timeline naturally diverged, creating two [[parallel universe]]s. ([[TV]]: {{cs|Inferno (TV story)}}, etc.) These parallel universes could be reached through the Time Vortex before the [[Last Great Time War]], but in the post-Gallifrey universe this became much more difficult, and dangerous to the structure of space-time. ([[TV]]: {{cs|Rise of the Cybermen (TV story)}}, {{cs|Doomsday (TV story)}})
 
In the post-Gallifrey universe, the Doctor and others often acted on their own to do the same. ([[TV]]: {{cs|Turn Left (TV story)}}, {{cs|Last of the Time Lords (TV story)}}, {{cs|The Mad Woman in the Attic (TV story)}}, etc.)
 
The [[Fourteenth Doctor]] asked [[Human (Double Danger)|a human]] to examine two pictures of [[the Toymaker]] following a [[rupture]] in time that resulted in the creation of multiple versions of [[reality]]. ([[PROSE]]: {{cs|Double Danger (game)}})
 
== Memories of altered history ==
{{Main|History-proofing}}
An ability once termed [[history-proofing]] ([[AUDIO]]: {{cs|The Ship of a Billion Years (audio story)}}) enabled inviduals to perceive alterations to time. This involved individuals being able to remember history both before and after the alteration, simultaneously, ([[TV]]: {{cs|Flesh and Stone (TV story)}}, etc.) although for many individuals the original version of history would be buried in their subconscious. ([[TV]]: {{cs|The Church on Ruby Road (TV story)}}, [[AUDIO]]: {{cs|Recruits (audio story)}}, [[PROSE]]: {{cs|Continuity Errors (short story)|page=214-239|name="errors"}}, etc.) Additionally, if an event was erased from someone's personal history, they had to make an extreme effort to remember. ([[TV]]: {{cs|Cold Blood (TV story)}})
 
== Personification ==
Like other cosmic principles, time was embodied by an [[Eternal]], named [[Time (mythology)|Time]], who chose the [[Seventh Doctor]] as her champion. ([[PROSE]]: {{cs|Happy Endings (novel)}}) Because the force of time was "encaged" at the [[Temple of Atropos]], in some sense this was also true of time's sentient avatar, who talked to the [[Ravager (The Halloween Apocalypse)|Ravager]]s and the [[Thirteenth Doctor]] there towards the end of the [[The Flux|Flux]] crisis. ([[TV]]: {{cs|The Vanquishers (TV story)}})

Time
You may wish to consult Time (disambiguation) for other, similarly-named pages.

Time was a fundamental physical quality, measuring the duration of events and the intervals between them. It could be seen as part of the fundamental structure of the universe, a dimension in which events happened in sequence. Space-time vessels, such as TARDISes, could travel along this dimension in the same way that ordinary space vessels could travel along the other dimensions.

Time travel[[edit] | [edit source]]

Main article: Time travel

New connections between different points in space-time could be created: for instance by time windows created by warp drives; (TV: The Girl in the Fireplace [+]Loading...["The Girl in the Fireplace (TV story)"]) time storms created by Fenric; (TV: Dragonfire [+]Loading...["Dragonfire (TV story)"], Silver Nemesis [+]Loading...["Silver Nemesis (TV story)"], The Curse of Fenric [+]Loading...["The Curse of Fenric (TV story)"]) or the cracks in the skin of the universe, which suddenly appeared at various times and places in the universe after a temporal explosion. (TV: Flesh and Stone [+]Loading...["Flesh and Stone (TV story)"], The Vampires of Venice [+]Loading...["The Vampires of Venice (TV story)"])

Furthermore, travel from any point to another was possible by passing through the Time Vortex, by using a vehicle such as a TARDIS or Dalek time machine (TV: The Chase [+]Loading...["The Chase (TV story)"], et al.) or a device such as a vortex manipulator, (TV: Utopia [+]Loading...["Utopia (TV story)"], The Sound of Drums [+]Loading...["The Sound of Drums (TV story)"], TV: Everything Changes [+]Loading...["Everything Changes (TV story)"], et al.) by creating a wormhole such as a time corridor (TV: The Evil of the Daleks [+]Loading...["The Evil of the Daleks (TV story)"], etc.), or even through direct psychic teleportation.

Changing history[[edit] | [edit source]]

The Tenth Doctor laboured in an effort to explain to humans how time was misunderstood and never strictly linear, that it was "a big ball of wibbly-wobbly, timey-wimey... stuff." (TV: Blink [+]Loading...["Blink (TV story)"]) Another time, he tried making it easier for his companion, Martha Jones, to understand by referencing Back to the Future to explain the mechanics of the "infinite temporal flux"; if the Carrionites succeeded in freeing the rest of their kind and taking over Earth, Martha would vanish as the future she came from would no longer exist.

However, erasing events from history did not always automatically change the future. Blocking chronons (e.g., with a TARDIS or a special-built device) could prevent objects from vanishing even though they no longer had a past. (GAME: City of the Daleks [+]Loading...["City of the Daleks (video game)"]) In a similar way, a paradox machine could be built (e.g., from a cannibalised TARDIS) to allow time paradoxes to persist without effect.

In a universe with time travel and a malleable space-time, there would be no fundamental stable meta-structure to history. However, the Time Lords imposed one, which they called the Web of Time, which connected the fragmentary nodes of history into a single whole. (AUDIO: Neverland [+]Loading...["Neverland (audio story)"]) This Web required maintenance, as when the Sixth Doctor explained that the destruction of Earth in 1985 would disrupt the Web. (TV: Attack of the Cybermen [+]Loading...["Attack of the Cybermen (TV story)"])

Even in the post-Gallifrey universe, some events were fixed points which must happen. One example was the volcanic eruption of Mount Vesuvius at Pompeii. (AUDIO: The Fires of Vulcan [+]Loading...["The Fires of Vulcan (audio story)"], TV: The Fires of Pompeii [+]Loading...["The Fires of Pompeii (TV story)"]) Changing fixed point events required highly advanced technology, and doing so could cause major damage to the continuum. (GAME: City of the Daleks [+]Loading...["City of the Daleks (video game)"])

Other moments were in flux, allowing minor changes to history. Some events even allowed dramatic changes in history, especially after the demise of the Time Lords in the Last Great Time War.

Time storms could occur inside a person’s time stream if time was allowed to slip into its allegedly naturally chaotic state. If someone was to enter their own time streams during a time storm, bad things could happen to that person. (TV: Once, Upon Time [+]Loading...["Once, Upon Time (TV story)"])

Parallel universes and alternate timelines[[edit] | [edit source]]

At historical choice points, the timeline naturally diverged, creating two parallel universes. (TV: Inferno [+]Loading...["Inferno (TV story)"], etc.) These parallel universes could be reached through the Time Vortex before the Last Great Time War, but in the post-Gallifrey universe this became much more difficult, and dangerous to the structure of space-time.

Memories of altered history[[edit] | [edit source]]

Main article: History-proofing

An ability once termed history-proofing (AUDIO: The Ship of a Billion Years [+]Loading...["The Ship of a Billion Years (audio story)"]) enabled inviduals to perceive alterations to time.
