A '''causal nexus''', ([[TV]]: ''[[Logopolis (TV story)|Logopolis]]'') also called a '''spatio-temporal causal nexus point '''([[AUDIO]]: [[The Mutant Phase (audio story)|The Mutant Phase]]), '''time-space nexus''', '''temporal nexus point''', '''causal nexus point''', '''nexus point''', or just '''nexus''', was a place in [[space]] and [[time]] that was malleable, ([[PROSE]]: ''[[Remembrance of the Daleks (novelisation)|Remembrance of the Daleks]]'') points in the [[space-time continuum]] that were very rare and hard to access. ([[PROSE]]: ''[[Invasion of the Cat-People (novel)|Invasion of the Cat-People]]'')
A '''causal nexus''', ([[TV]]: {{cs|Logopolis (TV story)}}) also called a '''spatio-temporal causal nexus point''', ([[AUDIO]]: {{cs|The Mutant Phase (audio story)}}) '''causal nexus point''', ([[PROSE]]: {{cs|The Ancestor Cell (novel)}}) '''nexus-point''', ([[COMIC]]: {{cs|Final Genesis (comic story)}}) '''nexus point''', ([[COMIC]]: {{cs|Empire of the Daleks (comic story)}}, etc.) '''Temporal Nexus Point''' (also abbreviated to '''TNP'''), ([[PROSE]]: {{cs|A Sourcebook for Field Agents (novel)}}, [[AUDIO]]: {{cs|The Marian Conspiracy (audio story)}}) '''temporal tipping point''', ([[TV]]: {{cs|Cold Blood (TV story)}}, {{cs|Dermot and the Doctor (TV story)}}) '''time-space nexus''', ([[PROSE]]: {{cs|Timewyrm: Genesys (novel)}}) or simply just '''nexus''',{{fact}} was the opposite of a [[fixed point in time]]; ([[TV]]: {{cs|Cold Blood (TV story)}}, [[AUDIO]]: {{cs|The Shadow Vortex (audio story)|timestamp=00:21:51}}) they were a place in [[space]] and [[time]] that was malleable. ([[PROSE]]: {{cs|Remembrance of the Daleks (novelisation)}})


Where time would normally be able to resist or absorb minor changes, the [[Third Doctor]] noted that some locations in space and time were temporal probability nexuses where multiple strands of causality were exposed and weak, and the smallest alteration could produce aberrant loops of existence or even new [[alternate timeline]]s. ([[PROSE]]: ''[[The Eye of the Giant (novel)|The Eye of the Giant]]'')
== Nature ==
A causal nexus existed in both [[space]] and [[time]].


As related to cause and effect, i.e. [[causality]], nexus points often served as areas for potential anomalies, since the [[Fourth Doctor]] stated that every point in time had its alternative. ([[TV]]: ''[[Pyramids of Mars (TV story)|Pyramids of Mars]]'')
=== Time ===
Temporal Nexus Points — as named by the [[Time Lord]]s — were parts of the [[time stream]] which were more vulnerable to change. Some planets and cultures, such as [[Gallifrey]] and [[Earth]], were of such importance that their entire history was a series of TNPs, making them receive the classification of "Class 1 Temporal Nexus Point". ([[PROSE]]: {{cs|A Sourcebook for Field Agents (novel)}})


== In time ==
The [[War Doctor]] described the opposite of a [[fixed point in time]] being "moments when everything can change." He explained that whole of [[1961]] was one such point. ([[AUDIO]]: {{cs|The Shadow Vortex (audio story)|timestamp=00:21:51}})
Causal nexuses existed within [[time fissure]]s, which were created all the time. Though not visible, they could be sensed by [[Time sensitivity|time sensitives]], and larger events could create fissures where [[time track]]s diverged from the nexus point, allowing for travel to [[parallel universe]]s. ([[AUDIO]]: ''[[The Wreck of the Titan (audio story)|The Wreck of the Titan]]'')


[[The Doctor's TARDIS]] became caught in a spatio-temporal causal nexus point when it hit a bump in the [[time track]], generated by the [[Dalek]]s of an [[alternate timeline]] using a [[time corridor]] to pull the [[Fifth Doctor]] into their future. ([[AUDIO]]: ''[[The Mutant Phase (audio story)|The Mutant Phase]]'')
The [[Eleventh Doctor]] described a temporal tipping point as a point that could "change [[future]] [[event]]s, create its own [[timeline]], its own [[reality]]." ([[TV]]: {{cs|Cold Blood (TV story)}})


The causal nexus divided when [[Nyssa]] changed [[history]] as part of the plan arranged by [[TARDIS (Prisoners of Fate)|the Doctor's first TARDIS]], causing the universe to exist in two quantum states and releasing [[Blinovitch Limitation Effect|blinovitch energy]]. When the [[time paradox]] was corrected with another paradox, the [[Fifth Doctor]] became the causal nexus as the paradox resulted from knowledge he would claim not to know in his personal future. ([[AUDIO]]: ''[[Prisoners of Fate (audio story)|Prisoners of Fate]]'')
One account asserted that such points in the [[space-time continuum]] were very rare and hard to access. ([[PROSE]]: {{cs|Invasion of the Cat-People (novel)}})


In keeping with this, the "[[Wenley Moor Affair]]" was a crucial nexus-point in Earth's [[time stream]] because countless futures could diverge from that moment into alternate realities. ([[COMIC]]: ''[[Final Genesis (comic story)|Final Genesis]]'') Similarly, the [[Eleventh Doctor]] identified the [[Cwmtaff incident]] as a [[temporal tipping point]] which would "change future events, create its own timeline, its own reality." ([[TV]]: ''[[Cold Blood (TV story)|Cold Blood]]'')
Where time would normally be able to resist or absorb minor changes, the [[Third Doctor]] noted that some locations in space and time were temporal probability nexuses where multiple strands of causality were exposed and weak, and the smallest alteration could produce aberrant loops of existence or even new [[alternate timeline]]s. ([[PROSE]]: {{cs|The Eye of the Giant (novel)}})


The [[Sixth Doctor]] detected a temporal nexus point which turned out to be [[Evelyn Smythe]], whose ancestors were slowly disappearing from history. ([[AUDIO]]: ''[[The Marian Conspiracy (audio story)|The Marian Conspiracy]]'')
As related to cause and effect, i.e. [[causality]], nexus points often served as areas for potential anomalies, since the [[Fourth Doctor]] stated that every point in time had its alternative. ([[TV]]: {{cs|Pyramids of Mars (TV story)}})


The planet [[Chronos]] in [[3286]] was a nexus point which could have led to the creation of the [[Cyberverse]]. ([[WC]]: ''[[Real Time (webcast)|Real Time]]'')
Causal nexuses existed within [[time fissure]]s, which were created all the time. Though not visible, they could be sensed by [[Time sensitivity|time sensitives]], and larger events could create fissures where [[time track]]s diverged from the nexus point, allowing for travel to [[parallel universe]]s. ([[AUDIO]]: {{cs|The Wreck of the Titan (audio story)}})


The temporal period surrounding [[1941]] [[Earth]] was a crucial nexus point in the planet's development, and any alterations, such as killing [[Adolf Hitler]], would disrupt the [[Web of Time]]. ([[COMIC]]: ''[[Me and My Shadow (comic story)|Me and My Shadow]]'')
Nexus points existed on [[Nexus world|other planets]] too, such as [[Bav (planet)|Bav]] and [[Teth]], which were also attacked by the [[Dalek]]s. ([[PROSE]]: {{cs|The Dalek Problem (novel)}})


[[Rose Tyler]], having travelled to [[Donna's World]], refused to reveal her name. She stated that "one word in the wrong place can change an entire causal nexus". ([[TV]]: ''[[Turn Left (TV story)|Turn Left]]'')
=== Space ===
Causal nexuses seemed to exist as actual structures of the [[universe]], based on [[planet]]s. [[Earth]] was widely recognised as one of the causal nexus points of [[Mutter's Spiral]]. ([[PROSE]]: {{cs|Cat's Cradle: Witch Mark (novel)}})


When asked why he couldn't just take the TARDIS back to the previous day, the [[Tenth Doctor]] recited, as if by rote, "I can't go back within my own timeline. I have to stay relative to [[Saxon Master|the Master]] within the causal nexus." He earlier called the same set of events a convergence. ([[TV]]: ''[[The End of Time (TV story)|The End of Time]]'')
''more to be added''


When the [[Kin (Nothing O'Clock)|Kin]]'s take-over of [[Earth]] led to [[human]]ity dying out by [[2010]], the [[Eleventh Doctor]] explained to [[Amy Pond]] that she still existed because she was an independent temporal nexus, "chrono-synchronistically established as an inverse...," but eventually agreed with Amy that the reason was "[[Wibbly wobbly, timey wimey|timey wimey]]." He also referred to the divergence point in [[1984]] for the [[alternate timeline]] as the nexus. ([[PROSE]]: ''[[Nothing O'Clock (short story)|Nothing O'Clock]]'')
=== Time and space ===
The particles of the [[Time Vortex]] could clump together at a nexus point. A [[TARDIS]] could hold onto a nexus point with mathematical anchors to resist the streaming delta flows. ([[PROSE]]: {{cs|Cat's Cradle: Witch Mark (novel)}})


While discussing changing her personal past, [[Amy Pond|Older Amy Pond]] capped a list comprised of destiny and causality with the nexus of time itself, a structure of causal nexus points that described or defined time. However, at the time she was referencing changing her own recent personal history from within a stable temporal anomaly that was generated artificially.

You may be looking for the Nexus creature.

A causal nexus, (TV: Logopolis [+]Loading...["Logopolis (TV story)"]) also called a spatio-temporal causal nexus point, (AUDIO: The Mutant Phase [+]Loading...["The Mutant Phase (audio story)"]) causal nexus point, (PROSE: The Ancestor Cell [+]Loading...["The Ancestor Cell (novel)"]) nexus-point, (COMIC: Final Genesis [+]Loading...["Final Genesis (comic story)"]) nexus point, (COMIC: Empire of the Daleks [+]Loading...["Empire of the Daleks (comic story)"], etc.) Temporal Nexus Point (also abbreviated to TNP), (PROSE: A Sourcebook for Field Agents [+]Loading...["A Sourcebook for Field Agents (novel)"], AUDIO: The Marian Conspiracy [+]Loading...["The Marian Conspiracy (audio story)"]) temporal tipping point, (TV: Cold Blood [+]Loading...["Cold Blood (TV story)"], Dermot and the Doctor [+]Loading...["Dermot and the Doctor (TV story)"]) time-space nexus, (PROSE: Timewyrm: Genesys [+]Loading...["Timewyrm: Genesys (novel)"]) or simply just nexus,[source needed] was the opposite of a fixed point in time; (TV: Cold Blood [+]Loading...["Cold Blood (TV story)"], AUDIO: The Shadow Vortex [+]Loading...{"timestamp":"00:21:51","1":"The Shadow Vortex (audio story)"}) they were a place in space and time that was malleable. (PROSE: Remembrance of the Daleks [+]Loading...["Remembrance of the Daleks (novelisation)"])

Nature[[edit] | [edit source]]

A causal nexus existed in both space and time.

Time[[edit] | [edit source]]

Temporal Nexus Points — as named by the Time Lords — were parts of the time stream which were more vulnerable to change. Some planets and cultures, such as Gallifrey and Earth, were of such importance that their entire history was a series of TNPs, making them receive the classification of "Class 1 Temporal Nexus Point". (PROSE: A Sourcebook for Field Agents [+]Loading...["A Sourcebook for Field Agents (novel)"])

The War Doctor described the opposite of a fixed point in time being "moments when everything can change." He explained that whole of 1961 was one such point. (AUDIO: The Shadow Vortex [+]Loading...{"timestamp":"00:21:51","1":"The Shadow Vortex (audio story)"})

The Eleventh Doctor described a temporal tipping point as a point that could "change future events, create its own timeline, its own reality." (TV: Cold Blood [+]Loading...["Cold Blood (TV story)"])

One account asserted that such points in the space-time continuum were very rare and hard to access. (PROSE: Invasion of the Cat-People [+]Loading...["Invasion of the Cat-People (novel)"])

Where time would normally be able to resist or absorb minor changes, the Third Doctor noted that some locations in space and time were temporal probability nexuses where multiple strands of causality were exposed and weak, and the smallest alteration could produce aberrant loops of existence or even new alternate timelines. (PROSE: The Eye of the Giant [+]Loading...["The Eye of the Giant (novel)"])

As related to cause and effect, i.e. causality, nexus points often served as areas for potential anomalies, since the Fourth Doctor stated that every point in time had its alternative. (TV: Pyramids of Mars [+]Loading...["Pyramids of Mars (TV story)"])

Causal nexuses existed within time fissures, which were created all the time. Though not visible, they could be sensed by time sensitives, and larger events could create fissures where time tracks diverged from the nexus point, allowing for travel to parallel universes. (AUDIO: The Wreck of the Titan [+]Loading...["The Wreck of the Titan (audio story)"])

Nexus points existed on other planets too, such as Bav and Teth, which were also attacked by the Daleks. (PROSE: The Dalek Problem [+]Loading...["The Dalek Problem (novel)"])

Space[[edit] | [edit source]]

Causal nexuses seemed to exist as actual structures of the universe, based on planets. Earth was widely recognised as one of the causal nexus points of Mutter's Spiral. (PROSE: Cat's Cradle: Witch Mark [+]Loading...["Cat's Cradle: Witch Mark (novel)"])

Time and space[[edit] | [edit source]]

The particles of the Time Vortex could clump together at a nexus point. A TARDIS could hold onto a nexus point with mathematical anchors to resist the streaming delta flows. (PROSE: Cat's Cradle: Witch Mark [+]Loading...["Cat's Cradle: Witch Mark (novel)"])

History[[edit] | [edit source]]

This section is not ordered by standard chronological order but rather an approximate chronological meta-time order.

In time[[edit] | [edit source]]

Pre-War era[[edit] | [edit source]]

Temporal Nexus Points attacked by the Daleks included Earth, Bav, and Teth. (PROSE: The Dalek Problem [+]Loading...["The Dalek Problem (novel)"])

The Seventh Doctor identified the Wenley Moor Affair as a crucial nexus-point in Earth's time stream such that a countless number of futures could be claimed from that moment with near-endless divergent realities. (COMIC: Final Genesis [+]Loading...["Final Genesis (comic story)"])

The Doctor's TARDIS became caught in a spatio-temporal causal nexus point when it hit a bump in the time track, generated by the Daleks of an alternate timeline using a time corridor to pull the Fifth Doctor into their future. (AUDIO: The Mutant Phase [+]Loading...["The Mutant Phase (audio story)"])

The Sixth Doctor detected a temporal nexus point which turned out to be Evelyn Smythe, whose ancestors were slowly disappearing from history. (AUDIO: The Marian Conspiracy [+]Loading...["The Marian Conspiracy (audio story)"])

The planet Chronos in 3286 was a nexus point which could have led to the creation of the Cyberverse. (WC: Real Time [+]Loading...["Real Time (webcast)"])

The temporal period surrounding 1941 Earth was a crucial nexus point in the planet's development, and any alterations, such as killing Adolf Hitler, would disrupt the Web of Time. (COMIC: Me and My Shadow [+]Loading...["Me and My Shadow (comic story)"])

War era[[edit] | [edit source]]

During the Last Great Time War, Stasi Lieutenant Kruger assumed that the War Doctor's claim that history would not remember men like him kindly, then Lara Zannis's scheme could not be successful as Earth continued to exist; exasperated, the Doctor explained that the opposite was true, as the whole of 1961, from beginning to end, was one big moment when "everything can change." (AUDIO: The Shadow Vortex [+]Loading...{"timestamp":"00:21:51","1":"The Shadow Vortex (audio story)"})

Post-War era[[edit] | [edit source]]

Rose Tyler, having travelled to a parallel world, refused to reveal her name. She stated that "one word in the wrong place can change an entire causal nexus". (TV: Turn Left [+]Loading...["Turn Left (TV story)"])

When asked why he couldn't just take the TARDIS back to the previous day, the Tenth Doctor recited, as if by rote, "I can't go back within my own timeline. I have to stay relative to the Master within the causal nexus." He earlier called the same set of events a convergence. (TV: The End of Time [+]Loading...["The End of Time (TV story)"])

The Eleventh Doctor identified the 2020 Cwmtaff incident as a "temporal tipping point", explaining that it was not a fixed point in time. (TV: Cold Blood [+]Loading...["Cold Blood (TV story)"])

When the Kin's take-over of Earth led to humanity dying out by 2010, the Eleventh Doctor explained to Amy Pond that she still existed because she was an independent temporal nexus, "chrono-synchronistically established as an inverse...," but eventually agreed with Amy that the reason was "timey wimey." He also referred to the divergence point in 1984 for the alternate timeline as the nexus. (PROSE: Nothing O'Clock [+]Loading...["Nothing O'Clock (short story)"])

While discussing changing her personal past, Older Amy Pond capped a list comprised of destiny and causality with the nexus of time itself, a structure of causal nexus points that described or defined time. However, at the time she was referencing changing her own recent personal history from within a stable temporal anomaly that was generated artificially. (TV: The Girl Who Waited [+]Loading...["The Girl Who Waited (TV story)"])

The Doctor also identified 26 January 2011, the night of the National Television Awards, as a temporal tipping point; "millions of people are going to be making vitally important decisions, and if they make just one tiny mistake the entire universe will be destroyed." (TV: Dermot and the Doctor [+]Loading...["Dermot and the Doctor (TV story)"])

The causal nexus divided when Nyssa changed history as part of the plan arranged by the Doctor's first TARDIS, causing the universe to exist in two quantum states and releasing blinovitch energy. When the time paradox was corrected with another paradox, the Fifth Doctor became the causal nexus as the paradox resulted from knowledge he would claim not to know in his personal future. (AUDIO: Prisoners of Fate [+]Loading...["Prisoners of Fate (audio story)"])

When time travelling Daleks failed to effectively control the Roman emperor Caligula, the Elite Guard Dalek abandoned the mission whilst noting that there were other nexus points in human history. (COMIC: Empire of the Daleks [+]Loading...["Empire of the Daleks (comic story)"])

In space[[edit] | [edit source]]

Logopolis and its inhabitants ran the Charged Vacuum Emboitements that kept N-Space going past the point of collapse. When the Tremas Master stopped Logopolis, he caused the unravelling of the whole causal nexus. This released a wave of entropy that engulfed parts of the universe, killing them. (TV: Logopolis [+]Loading...["Logopolis (TV story)"])

A nexus resided in the transjovian space near Jupiter, which the Hand of Omega reached using faster-than-light travel, after which traversing the nexus to reach Skaro in its own time zone by punching a hole in reality. (PROSE: Remembrance of the Daleks [+]Loading...["Remembrance of the Daleks (novelisation)"])

The Seventh Doctor considered (and blamed) Earth as a "major time-space nexus" for the reason he was on Earth at certain times and the coincidences that came from that. These included him being in Mesopotamia in the time of Gilgamesh (PROSE: Timewyrm: Genesys [+]Loading...["Timewyrm: Genesys (novel)"]) and being in Ife during the 10th century. In the latter travel, there may have been static electricity involved which made the Yoruba believe he was Shango, the thunder god. (PROSE: Transit [+]Loading...["Transit (novel)"])

The Edifice's interior dimensions were mapped onto its exterior, making it the same size inside as outside, cancelling its dimensional transcendence. This also caused it to become a nexus point, affecting past and future events along the causal pathways, generating temporal anomalies in the resulting temporal pulses. (PROSE: The Ancestor Cell [+]Loading...["The Ancestor Cell (novel)"])

Outside time and space[[edit] | [edit source]]

A hyper reality nexus was created by Godwanna to access hyper reality and absorb all the energy she created from destroying Earth in 1994. (PROSE: Invasion of the Cat-People [+]Loading...["Invasion of the Cat-People (novel)"])

There were points in the universe where parallels collided, where the Parallel Sect created a reality web threaded through the whole infinity of the universe. (AUDIO: The End of the Line [+]Loading...["The End of the Line (audio story)"])
