A '''universe''' was a particular spatial reality.


These Universes exist within an expanse called the [[Void]] ([[DW]]: ''[[Army of Ghosts]]''), an ur-space often conceptualised as an ocean in which they float ([[FP]]: ''[[Dead Romance]] 2nd Ed.'': ''[[A Cosmology of the Spiral Politic]]'').
== Cosmology ==
Multiple universes existed ([[TV]]: ''[[Inferno (TV story)|Inferno]]'', ''[[Rise of the Cybermen (TV story)|Rise of the Cybermen]]'', [[PROSE]]: ''[[A Bright White Crack (short story)|A Bright White Crack]]'', [[COMIC]]: ''[[Assimilation² (comic story)|Assimilation²]]'', [[AUDIO]]: ''[[The Library in the Body (audio story)|The Library in the Body]]'', etc.),  separated by an expanse called [[the Void]]. ([[TV]]: ''[[Army of Ghosts (TV story)|Army of Ghosts]]'') Prior to the [[Last Great Time War]], the [[Time Vortex]] could be used to access one another. [[Post-Time War universe|Since the War]], the pathways had closed ([[TV]]: ''[[Rise of the Cybermen (TV story)|Rise of the Cybermen]]'') and travel usually only occurred through a [[Void Ship]] or the [[reality bomb]] breaking down the fabric of the walls of reality surrounding each universe. ([[TV]]: ''[[Army of Ghosts (TV story)|Army of Ghosts]]'', ''[[The Stolen Earth (TV story)|The Stolen Earth]]'' / ''[[Journey's End (TV story)|Journey's End]]'')


A number of universes exist ([[DW]]: ''[[Inferno]]''), but it is not known if that number is infinite or merely incalculably huge ([[FP]]: ''[[Dead Romance]] 2nd Ed.'': ''[[A Cosmology of the Spiral Politic]]''). Some exist 'sideways' or 'parallel' to each other ([[DW]]: ''[[Battlefield]]''), although such spacial language must be understood as simplification given that 'space' is a phenomenon local to ''within'' universes ([[FP]]: ''[[Dead Romance]] 2nd Ed.'': ''[[A Cosmology of the Spiral Politic]]''). Likewise, some exist 'before' ([[NA]]: ''[[All-Consuming Fire]]'') or 'after' ([[MA]]: ''[[Millennial Rites]]'') each other, although such temporal language must be understood as simplification given that 'time' is a phenomenon local to ''within'' universes ([[FP]]: ''[[Dead Romance]] 2nd Ed.'': ''[[A Cosmology of the Spiral Politic]]'').
Some universes existed sideways or parallel to each other. ([[TV]]: ''[[Battlefield (TV story)|Battlefield]]'') Likewise, some existed before ([[PROSE]]: ''[[All-Consuming Fire (novel)|All-Consuming Fire]]'') or after ([[PROSE]]: ''[[Millennial Rites (novel)|Millennial Rites]]'') each other.


Many universes develop a civilisation equivalent to the [[Time Lord]]s - the first culture within a given reality to reach a level of sophistication which allows them to tailor the laws of that universe to their own nature ([[MA]]: ''[[Cold Fusion]]'').

==The Doctor's Universe==
The composition of the universe consisted of [[galaxy|galaxies]] which contained [[star]]s which were orbited by [[planet]]ary bodies. [[Earth]], for example, lay in the [[Sol]] system of [[Mutter's Spiral]], the galaxy closest to the [[Andromeda (galaxy)|Andromeda Galaxy]].
The universe which produced [[the Doctor]] is the site of the majority of his adventures.


Infinite in [[space]] and constantly expanding ([[DW]]: ''[[Genesis of the Daleks]]''), it was created roughly fourteen billion years ago as a consequence of the [[Big Bang]]. The [[Time Lords]] refer to this as 'Event One' ([[DW]]: ''[[Castrovalva]]'').
=== Parallels ===
Although it was possible for complete new universes to form by 'branching off' from specific points in another universe's history, doing so cut the lifespan of the original universe in half. ([[PROSE]]: ''[[Blood Heat (novel)|Blood Heat]]'')


'Event Two' signifies the end of the universe ([[PDA]]: ''[[The Infinity Doctors]]''), which has variously been projected to occur in [[The far future|60,000,000,000 AD]] ([[BFA]]: ''[[Zagreus (audio story)|Zagreus]]''), [[The far future|100,000,000,000,000 AD]] ([[DW]]: ''[[Utopia (TV story)|Utopia]]'') or [[The far future|100,000,000,000,000,000,000,000,000,000,000 AD]] ([[PDA]]: ''[[The Infinity Doctors]]'').
According to [[the Bookwyrm]], people claimed that incarnations of [[Jenny Everywhere]] existed in every universe capable of supporting [[life]]. ([[PROSE]]: {{cs|Previously On... The Multiverse (short story)|page=20}})


:''There are several possibilities for the discrepancies. Possibly, the beings who made the calculations were simply wrong, either how close they were to the end or beginning of the universe. The fact that the universe reached heat-death before those points might have also affected when the universe would actually come to an end. Finally, the creation of universes by [[Universe#'Sideways'|branching off]] would have also decreased the potential age of the universe.''
=== Sentience ===
According to the [[Eleventh Doctor]], at least [[N-Space|his universe]] was born alive, but it could only become aware of itself by developing sensors across its surface, known as [[lifeform|life forms]], each of which suffered a temporary delusion of separate identity during data collection - called [[consciousness]] - but in reality had little to none individual existence. ([[PROSE]]: ''[[The Day of the Doctor (novelisation)|The Day of the Doctor]]'') [[Coincidence]]s occurred as it was a form of amusement for the universe. ([[TV]]: ''[[Closing Time (TV story)|Closing Time]]'') It also rewarded those, like the Doctor, who repeatedly saved it from destruction. ([[TV]]: ''[[The Snowmen (TV story)|The Snowmen]]'') [[Larles]] considered the idea that the Totality was conscious to be an "outdated theory", although it "could still be true in an abstract sense". ([[PROSE]]: ''[[The Aftermath (short story)|The Aftermath]]'')


The universe passed the point where it should have succumbed to heat death long before any of these dates, but vented most of its entropy into [[E-Space]]. ([[DW]]: ''[[Logopolis (TV story)|Logopolis]]'')
== History ==
=== Before ===
The [[pre-universe]] which existed prior to the Doctor's had a green void, stars shaped like doughnuts and physical laws closer to what might be understood as [[magic]]. ([[PROSE]]: ''[[Millennial Rites (novel)|Millennial Rites]]'')


The [[Time Lord]]s of [[Gallifrey]] were, as the first sentient culture to develop within this universe ([[NA]]: ''[[Lucifer Rising]]''), responsible for setting the parameters within which the universe operates ([[NA]]: ''[[Sky Pirates!]]''). They expunged [[magic]] in favour of [[science]] as the basic governing principle ([[NA]]: ''[[Cat's Cradle: Time's Crucible]]'', ''[[Christmas on a Rational Planet]]''). They established the [[morphic field]] that would seem to favour the development of [[Near-human|humanoid]] life. They established the [[Web of Time]] which guaranteed the universe a stable, linear, history ([[BFA]]: ''[[Neverland]]'', [[FP]]:''[[The Book of the War]]'').
Knowledge of this universe was a closely guarded secret, and was only in the Doctor's possession as a result of his connection to [[the Matrix]] during his time as [[Lord President]]. ([[PROSE]]: ''[[Millennial Rites (novel)|Millennial Rites]]'') Even then, the knowledge would ultimately have proven temporary; in his [[Sixth Doctor|sixth]] and [[Seventh Doctor|seventh]] lives the Doctor was fully conversant with the details and specifics of this universe ([[PROSE]]: ''[[All-Consuming Fire (novel)|All-Consuming Fire]]'', [[PROSE]]: ''[[Synthespians™ (novel)|Synthespians™]]''), but by his [[Tenth Doctor|tenth]] life it was almost an article of religious faith to him that such a universe could not have existed. ([[TV]]: ''[[The Satan Pit (TV story)|The Satan Pit]]'')


With the [[Time Lords]] now lost to the [[Last Great Time War]], this particular universe has become a more uncertain and dangerous place. The ability to travel to other universe was stopped ([[DW]]: ''[[Rise of the Cybermen]]'') and the creation of [[paradox]]es has a much more dangerous affect ([[DW]]: ''[[Father's Day]]'').
This universe's equivalent to the [[Time Lord]]s were the [[Great Old One]]s, who found a means by which to survive into the next. ([[PROSE]]: ''[[All-Consuming Fire (novel)|All-Consuming Fire]]'', [[PROSE]]: ''[[Millennial Rites (novel)|Millennial Rites]]'') [[The Beast (The Impossible Planet)|The Beast]] claimed to have existed before the universe. ([[TV]]: ''[[The Impossible Planet (TV story)|The Impossible Planet]]'') It was also speculated that the [[Ancient Lights]] came from the previous universe. ([[TV]]: ''[[Secrets of the Stars (TV story)|Secrets of the Stars]]'')


=='Before'==
=== Current ===
The so-called '[[Pre-Universe]]' which existed prior to the Doctor's had green space, stars shaped like doughnuts and physical laws closer to what might be understood as [[magic]] ([[MA]]: ''[[Millennial Rites]]'').
The universe of [[the Doctor]] and of the [[Time Lord]]s was known as [[N-Space]]. It was in a state of constant expansion ([[TV]]: ''[[Genesis of the Daleks (TV story)|Genesis of the Daleks]]'') and was created out of a continually existing black void roughly thirteen ([[TV]]: ''[[Secrets of the Stars (TV story)|Secrets of the Stars]]'') or fourteen billion years [[BC]] in what was known as [[Event One]]. ([[TV]]: ''[[Castrovalva (TV story)|Castrovalva]]'')


Knowledge of this universe was a closely guarded secret, and was only in the Doctor's possession as a result of his connection to the [[Matrix]] during his time as [[Lord President]] ([[MA]]: ''[[Millennial Rites]]'', [[DW]]: ''[[The Invasion of Time]]''). Even then, the knowledge would ultimately prove temporary; In his [[Sixth Doctor|Sixth]] and [[Seventh Doctor|seventh]] life the Doctor was fully conversant with the details and specifics of this universe ([[NA]]: ''[[All-Consuming Fire]]'', [[PDA]]: ''[[Synthespians™]]''), whereas by his [[Tenth Doctor|tenth]] it would almost be an article of religious faith to him that such a universe could not have existed ([[DW]]: ''[[The Impossible Planet]]'').
The universe passed the point where it should have succumbed to heat death by the [[20th century]], but vented most of its [[entropy]] into [[E-Space]]. ([[TV]]: ''[[Logopolis (TV story)|Logopolis]]'')


This universe's equivalent to the Time Lords were the [[Old One]]s, who found a means by which to survive into the next. ([[NA]]: ''[[All-Consuming Fire]]'', [[MA]]: ''[[Millennial Rites]]'') [[The Beast]]'s claims would also suggest he originated in this cosmos, as the [[Disciples of Light]] might have. ([[DW]]: ''[[The Impossible Planet]]'')
The universe was replete with [[pocket universe]]s and other realms or domains discrete from the wider continuum. Some of these existed in exotic special dimensions such as [[Calabi-Yau Space]], ([[PROSE]]: ''[[The Quantum Archangel (novel)|The Quantum Archangel]]'') some folded into quirks of perceptual history such as the [[Eleven-Day Empire]] ([[PROSE]]: ''[[Interference - Book One (novel)|Interference - Book One]]'') and others, such as [[Mictlan]], had no measurable existence beyond the purely conceptual. ([[PROSE]]: ''[[Alien Bodies (novel)|Alien Bodies]]'')


=='After'==
When the [[Olympian]] [[Prometheus (The Life Bringer!)|Prometheus]] stole [[life spore]]s from the planet [[Olympus]] and let them go across the universe, he created life. This angered [[Zeus (The Life Bringer!)|Zeus]], who chained Prometheus to a mountain on an unknown planet for his actions. ([[COMIC]]: ''[[The Life Bringer! (comic story)|The Life Bringer!]]'') [[Greyjan the Sane]], on the other hand, stated that life [[evolution|evolved]] from a single [[ancestor cell]]. This didn't include more [[Transcendental being|exotic lifeforms]], which came into being soon after the creation of the universe. ([[PROSE]]: ''[[The Ancestor Cell (novel)|The Ancestor Cell]]'')
The universe that followed the Doctor's would be a pink void, interspersed with green mists of orbiting plankton.
[[Saraquazel]] would become this universe's equivalent of a [[Time Lord]]. ([[MA]]: ''[[Millennial Rites]]'').


The [[City of the Saved]] existed 'inbetween' the end of the Doctor's universe and the start of this one. ([[FP]]: ''[[Of the City of the Saved...]]'')
The [[Time Lord]]s of [[Gallifrey]], as the first sentient culture to develop within their universe, ([[PROSE]]: ''[[Lucifer Rising (novel)|Lucifer Rising]]'') were responsible for setting the parameters within which the universe operated. ([[PROSE]]: ''[[Sky Pirates! (novel)|Sky Pirates!]]'') They expunged [[magic]] in favour of science as the basic governing principle. ([[PROSE]]: ''[[Cat's Cradle: Time's Crucible (novel)|Cat's Cradle: Time's Crucible]]'', ''[[Christmas on a Rational Planet (novel)|Christmas on a Rational Planet]]'') They also established the [[morphic field]] that favoured the development of [[humanoid]] life. ([[PROSE]]: ''[[Lucifer Rising (novel)|Lucifer Rising]]'') They established the [[Web of Time]] which guaranteed the universe a stable, linear history. ([[AUDIO]]: ''[[Neverland (audio story)|Neverland]]'')


The inhabitants of the City of the Saved once believed they had penetrated into this universe and established a colony there, but in fact they were deceived and had in fact only reached a simulated environment inside the hostile [[TARDIS]] known as [[Antipathy]]. ([[FP]]: ''[[Of the City of the Saved...]]'')
After the Time Lords were lost to the [[Last Great Time War]], the universe became a more risky and dangerous place. Travel to parallel universes became seemingly impossible ([[TV]]: ''[[Rise of the Cybermen (TV story)|Rise of the Cybermen]]'') and the creation of [[time paradox]]es had a much more dangerous effect. ([[TV]]: ''[[Father's Day (TV story)|Father's Day]]'')


=='Sideways'==
The destruction of [[the Doctor's TARDIS]] created [[Time Field|cracks in time]] throughout time and space which began erasing the universe. By piloting the [[Pandorica]] (which basically contained a blueprint for the universe) into the heart of the TARDIS explosion (which was happening at all points in space and time), the [[Eleventh Doctor]] rebooted the universe, restoring it to its original state. It is unclear, however, if everything erased by the cracks were restored. [[Amy Pond]]'s parents, her husband [[Rory Williams|Rory]] and the Doctor were all restored, but this was only due to her specifically remembering them and the influence of one of the cracks on her life for years. In the case of the Doctor, she had to actively remember him in order to restore him after he was erased by the cracks while restoring the universe, so everything else erased, such as the [[Weeping Angel]]s, may not have been restored. ([[TV]]: ''[[The Pandorica Opens (TV story)|The Pandorica Opens]]'', ''[[The Big Bang (TV story)|The Big Bang]]'')
Most 'parallel' universes are exactly that; ''parallel''. They run alongside each other but have an independent existence. They may share many common features but do not 'diverge' or 'branch off' from each other at any specific point ([[FP]]: ''[[Dead Romance]] 2nd Ed.'': ''[[A Cosmology of the Spiral Politic]]'').


The countless worlds in which the Roman Empire never fell or in which the Nazis won World War II ([[DWM]]: ''[[The Iron Legion]]'',[[FP]]: ''[[Warlords of Utopia]]'') are not twigs off the branch of some 'main' universe or paths that have split off at some particular juncture. They are entirely separate creations that share many, but not all, of the features of the familiar universe ([[FP]]: ''[[Dead Romance]] 2nd Ed.'': ''[[A Cosmology of the Spiral Politic]]''). The same would seem to hold true of [[Pete's World]] and [[Inferno Earth]] ([[DW]]: ''[[Rise of the Cybermen]]'',''[[Inferno]]').
=== After ===
The [[end of the universe]], also known as Event Two, ([[PROSE]]: ''[[The Infinity Doctors (novel)|The Infinity Doctors]]'') was variously projected to have occurred in [[60000000000|60 billion AD]], ([[AUDIO]]: ''[[Zagreus (audio story)|Zagreus]]'') [[100000000000000|100 trillion AD]] ([[TV]]: ''[[Utopia (TV story)|Utopia]]'') or [[100000000000000000000000000000000|100,000,000,000,000,000,000,000,000,000,000 AD]]. ([[PROSE]]: ''[[The Infinity Doctors (novel)|The Infinity Doctors]]'')


Those universes which share the most features in common may be considered as being located 'closest' to each other and those which share the least features in common may be considered as being 'furthest away' from each other. Although, again, the spacial terminology here is a simplification as 'space' only exists ''within'' universes ([[FP]]: ''[[Dead Romance]] 2nd Ed.'': ''[[A Cosmology of the Spiral Politic]]'').
Though the [[Tenth Doctor]] denied the existence of a universe before his own, ([[TV]]: ''[[The Impossible Planet (TV story)|The Impossible Planet]]'') he remained aware that the death of his universe would have been followed by the birth of another. ([[TV]]: ''[[Army of Ghosts (TV story)|Army of Ghosts]]'') Many time travellers killed themselves at the end of the universe in the [[Institute of Time]] because they feared the universe's heat death. ([[PROSE]]: ''[[The End (short story)|The End]]'')


It '''is''' however possible for complete new universes to be formed by 'branching off' from specific points in another universe's history. The difficulty with this though is  that it cuts the lifespan of the original universe in half. ([[NA]]: ''[[Blood Heat]]'')
The [[after-universe]] was a [[pink]] void interspersed with [[yellow]] mists of orbiting plankton and [[Saraquazel]], who became its equivalent of a Time Lord.

A healthier way for a universe to reproduce is for it to develop within it a species capable of 'engineering' a new universe from scratch ([[FP]]: ''[[Dead Romance]] 2nd Ed.'': ''[[A Cosmology of the Spiral Politic]]''). The Time Lords never apparently attained this level of accomplishment. However an unpopular fringe theory on [[Gallifrey]] held that their own entire reality had been engineered in this way by the [[21st Century]] [[Humanity]] of some other universe ([[FP]]: ''[[The Book of the War]]'').

Universe
The Doctor's TARDIS passes through the Bubble universe rift leading to House's bubble universe. (TV: The Doctor's Wife)
You may be looking for Doctor Who universe or the Doctor's universe.

A universe was a particular spatial reality.

Cosmology[[edit] | [edit source]]

Multiple universes existed (TV: Inferno, Rise of the Cybermen, PROSE: A Bright White Crack, COMIC: Assimilation², AUDIO: The Library in the Body, etc.), separated by an expanse called the Void. (TV: Army of Ghosts) Prior to the Last Great Time War, the Time Vortex could be used to access one another. Since the War, the pathways had closed (TV: Rise of the Cybermen) and travel usually only occurred through a Void Ship or the reality bomb breaking down the fabric of the walls of reality surrounding each universe. (TV: Army of Ghosts, The Stolen Earth / Journey's End)

Some universes existed sideways or parallel to each other. (TV: Battlefield) Likewise, some existed before (PROSE: All-Consuming Fire) or after (PROSE: Millennial Rites) each other.

Many universes developed a civilisation equivalent to that of the Time Lords - the first culture within a given reality to reach a level of sophistication which allowed them to tailor the laws of that universe to their own nature. (PROSE: Cold Fusion)

The composition of the universe consisted of galaxies which contained stars which were orbited by planetary bodies. Earth, for example, lay in the Sol system of Mutter's Spiral, the galaxy closest to the Andromeda Galaxy.

Parallels[[edit] | [edit source]]

Although it was possible for complete new universes to form by 'branching off' from specific points in another universe's history, doing so cut the lifespan of the original universe in half. (PROSE: Blood Heat)

According to the Bookwyrm, people claimed that incarnations of Jenny Everywhere existed in every universe capable of supporting life. (PROSE: Previously On... The Multiverse [+]Loading...{"page":"20","1":"Previously On... The Multiverse (short story)"})

History[[edit] | [edit source]]

Before[[edit] | [edit source]]

The pre-universe which existed prior to the Doctor's had a green void, stars shaped like doughnuts and physical laws closer to what might be understood as magic. (PROSE: Millennial Rites)

Knowledge of this universe was a closely guarded secret, and was only in the Doctor's possession as a result of his connection to the Matrix during his time as Lord President.

(TV: The Satan Pit)

This universe's equivalent to the Time Lords were the Great Old Ones, who found a means by which to survive into the next. (PROSE: All-Consuming Fire, PROSE: Millennial Rites) The Beast claimed to have existed before the universe. (TV: The Impossible Planet) It was also speculated that the Ancient Lights came from the previous universe. (TV: Secrets of the Stars)

Current[[edit] | [edit source]]

The universe of the Doctor and of the Time Lords was known as N-Space. It was in a state of constant expansion (TV: Genesis of the Daleks) and was created out of a continually existing black void roughly thirteen (TV: Secrets of the Stars) or fourteen billion years BC in what was known as Event One. (TV: Castrovalva)

The universe passed the point where it should have succumbed to heat death by the 20th century, but vented most of its entropy into E-Space. (TV: Logopolis)

The universe was replete with pocket universes and other realms or domains discrete from the wider continuum. Some of these existed in exotic special dimensions such as Calabi-Yau Space, (PROSE: The Quantum Archangel) some folded into quirks of perceptual history such as the Eleven-Day Empire (PROSE: Interference - Book One) and others, such as Mictlan, had no measurable existence beyond the purely conceptual. (PROSE: Alien Bodies)

When the Olympian Prometheus stole life spores from the planet Olympus and let them go across the universe, he created life. This angered Zeus, who chained Prometheus to a mountain on an unknown planet for his actions. (COMIC: The Life Bringer!) Greyjan the Sane, on the other hand, stated that life evolved from a single ancestor cell. This didn't include more exotic lifeforms, which came into being soon after the creation of the universe. (PROSE: The Ancestor Cell)

The Time Lords of Gallifrey, as the first sentient culture to develop within their universe, (PROSE: Lucifer Rising) were responsible for setting the parameters within which the universe operated. (PROSE: Sky Pirates!) They expunged magic in favour of science as the basic governing principle. (PROSE: Cat's Cradle: Time's Crucible, Christmas on a Rational Planet) They also established the morphic field that favoured the development of humanoid life. (PROSE: Lucifer Rising) They established the Web of Time which guaranteed the universe a stable, linear history. (AUDIO: Neverland)

After the Time Lords were lost to the Last Great Time War, the universe became a more risky and dangerous place. Travel to parallel universes became seemingly impossible (TV: Rise of the Cybermen) and the creation of time paradoxes had a much more dangerous effect. (TV: Father's Day)

The destruction of the Doctor's TARDIS created cracks in time throughout time and space which began erasing the universe. By piloting the Pandorica (which basically contained a blueprint for the universe) into the heart of the TARDIS explosion (which was happening at all points in space and time), the Eleventh Doctor rebooted the universe, restoring it to its original state.

In the case of the Doctor, she had to actively remember him in order to restore him after he was erased by the cracks while restoring the universe, so everything else erased, such as the Weeping Angels, may not have been restored. (TV: The Pandorica Opens, The Big Bang)

After[[edit] | [edit source]]

The end of the universe, also known as Event Two, (PROSE: The Infinity Doctors) was variously projected to have occurred in 60 billion AD, (AUDIO: Zagreus) 100 trillion AD (TV: Utopia) or 100,000,000,000,000,000,000,000,000,000,000 AD. (PROSE: The Infinity Doctors)

Though the Tenth Doctor denied the existence of a universe before his own, (TV: The Impossible Planet) he remained aware that the death of his universe would have been followed by the birth of another. (TV: Army of Ghosts) Many time travellers killed themselves at the end of the universe in the Institute of Time because they feared the universe's heat death. (PROSE: The End)

The after-universe was a pink void interspersed with yellow mists of orbiting plankton and Saraquazel, who became its equivalent of a Time Lord. (PROSE: Millennial Rites) The Zytragupten also inhabited this universe. (COMIC: The Stockbridge Child)
