Web of Time

The Web of Time, (TV: Attack of the Cybermen, et al.) or simply the meta-structure of history, (PROSE: The Book of the War, et al.) was the orderly structure of the universe's history, built and maintained by the Time Lords. It was consubstantial with Gallifrey's noosphere.

The rationality-bound universe was once described by Chris Cwej as the Linear Universe. (PROSE: A Bright White Crack) The Spiral Politic was a conceptual map of universal history, and the term was sometimes used as a metonym for the structure of history, as well as for the universe itself. (PROSE: The Book of the War)

Structure
The meta-structure of history was made of a number of temporal threads, which were not initially dependent upon each other until the Great Houses effected the "anchoring", weaving them together into one whole with the Homeworld at the centre. The machine-heart at the centre of the web (PROSE: The Book of the War) included the Eye of Harmony, (COMIC: The Final Chapter) which served as "the hitching post of chronology". (AUDIO: Neverland) However, when the Yssgaroth broke through at the moment of the anchoring and wrecked the machine-heart, they created the caldera, a gap in space-time, which became the de facto "centre of history". (PROSE: The Book of the War) The Untempered Schism was the heart of the caldera. (PROSE: Tempered)

The structure was held together by strategic "node points" in space-time, holding each of the threads in place. (PROSE: The Book of the War) They took the form of events with effects so significant that they would cause significant disruption to the Web if changed. This could cause disastrous repercussions in every corner of the universe, killing billions, instantly disappearing major civilisations, and threatening the fabric of the universe itself. (PROSE: Attack of the Cybermen) If such a fixed point in time was altered, the whole of Time would "disintegrate": linearity would break down as all of history began to collapse in on itself, (TV: The Wedding of River Song) and the universe itself would ultimately be destroyed, except for realms excised from normal space-time, like the Eleven-Day Empire. (PROSE: The Book of the War)

The Web of Time was not without its "weak points", such as the village of Foxgrove, which was situated on a fault line. This allowed the Trickster to break into N-Space from the limbo dimensions when Sarah Jane Smith saved her parents who were destined to die in 1951. The Trickster was ultimately banished when Sarah Jane's parents chose to meet their fates. (TV: The Temptation of Sarah Jane Smith)

Amaranths could also be used to rebuild unstable or discontinuous elements of the universe (PROSE: Christmas on a Rational Planet) along the lines of the established laws of the Spiral Politic. (PROSE: Against Nature) The Dalek Time Controller, upon being propelled through the Time Vortex, found it had all of eternity to study the ebb and flow of the universe and history. The "patterns" of time and space were imprinted into its mind, teaching the Dalek about "the beginning and end of everything". (AUDIO: To the Death)

Relationship to the Time Lords
Because the founding members of the Great Houses "stitched" their biodata into the structure itself upon the anchoring of the thread, their kind's noosphere was directly linked to the structure of time. (PROSE: The Book of the War) The Ninth Doctor told Rose Tyler that he could constantly see "all that was" "all that could ever be", though he rarely acknowledged it. (TV: The Parting of the Ways) As demonstrated by the Tenth Doctor, a Time Lord could also feel which events were fixed points in time and which were not. (TV: The Fires of Pompeii)

Most of the Web was in constant flux, like an ocean of shifting possibilities; it could only be frozen into certainty by a Time Lord's direct touch or intervention, through the Observer Effect. It was for this reason that the Time Lords established their non-interference policy. (PROSE: The Gallifrey Chronicles)

Changeability
Even concerning events that were not fixed points, time could be crystallized along a particular web-way, (PROSE: The Sands of Time) making that event a fixed part of the Web of Time so that it had always happened and would always happen. (PROSE: Attack of the Cybermen) This could occur when a person learned about their personal future, (PROSE: The Sands of Time, TV: The Angels Take Manhattan) an effect first predicted by Blinovitch. (PROSE: The Sands of Time)

The Sixth Doctor once explained that the Web of Time would be disrupted if Earth were destroyed before its time, (TV: Attack of the Cybermen) as Earth was a nexus world linked to the destinies of many major intergalactic powers. (PROSE: Alien Bodies) The saving of the Titanic would have similarly perturbed the Web by condemning all the later ships that were saved by round-the-clock radio surveillance, lifeboat capacities, or the International Ice Patrol, all of which were developed due to the Titanic's sinking. (PROSE: The Left-Handed Hummingbird)

However, more generally, the Eighth Doctor explained that the Web of Time was resilient. In some cases, events could be reshaped; for instance, some people could safely have been made to die early if they led quiet, unobtrusive lives without any children. (AUDIO: The Zygon Who Fell to Earth) An example of this was Andrew Edwardson, who lived a quiet life on his own, so his death could not disrupt causality. (AUDIO: My Dinner with Andrew) Removing such a person was a mere "hiccup" in causality, easily mended. (AUDIO: Neverland) In legal terms, such people whose deaths would have little to no impact on the causal nexus were deemed "future-proof". (AUDIO: Moving Target)

Upon finding Daleks attacking the 1966 World Cup, the Fourteenth Doctor remarked that attacking the football match would not be enough to change history. (COMIC: Liberation of the Daleks)

In other cases, when specific events were removed from the Web, analogous events would take their place. (PROSE: The Left-Handed Hummingbird) The First Doctor often found that "things balance out in curious ways". (AUDIO: Daybreak) For instance, if Adolf Hitler was prevented from rising to power, a different man would have taken control of the Nazi party and begun World War II, though the War would've ended differently. (PROSE: Timewyrm: Exodus)

Alternatively, Susan explained that if Ian had written a letter to Napoléon Bonaparte and told him of the events that were to happen, Napoléon would've forgotten or lost it or believed it to be written by a mad man. Barbara also speculated that if they fired a gun at Napoléon, the bullet would've missed. (TV: The Reign of Terror) However, an Imperial Dalek plot to alter the Battle of Waterloo was close to changing history, forcing the Sixth Doctor to intervene and meet with Bonaparte. (AUDIO: The Curse of Davros)

History
Rather than being a necessary fundamental aspect of the universe, the Web of Time was a meta-structure created and imposed on the universe from the Matrix by the Time Lords during the anchoring of the thread, when Rassilon used the Eye of Harmony as "the hitching post of chronology". (AUDIO: Neverland, PROSE: The Book of the War) Before this, the universe had no history or defined set of physical laws. (PROSE: Christmas on a Rational Planet)

Since the Yssgaroth emerged during the anchoring, the Yssgaroth taint remained in the fabric of the universe, irremovable except through the unweaving of time itself. The Book of the War speculated that the Yssgaroth were areas of hostile anti-structure produced by the collision of the Spiral Politic with the Spiral Yssgaroth's foreign and hostile structures and protocols. (PROSE: The Book of the War) Lolita thought that the Vampire Wars had dictated the shape of the Spiral Politic for its first ten million years. (PROSE: Toy Story)

The techniques which led to history's creation were almost rediscovered by the Democratic Saturnian Entanglement, prompting the Superiors to have Chris Cwej to implement the rings of Saturn, which were in fact disintegrators, ready to destroy the DSE if they ever tried to go further with their research. (PROSE: A Bright White Crack)

Events in the Web of Time
Events the Doctor stated as being part of the Web included the destruction of Mondas, (TV: Attack of the Cybermen) the sinking of the Titanic, (PROSE: The Left-Handed Hummingbird) the destruction of the Halcyon race through the Ice Warriors creating an atmosphere on Halcyon more suited to them, (AUDIO: The Resurrection of Mars) Deimos becoming an artificial sun that heated Mars, (AUDIO: The Resurrection of Mars) Gallifrey's Racnoss Wars, (AUDIO: Empire of the Racnoss) the burning of Joan of Arc, the assassination of Francis Ferdinand, (AUDIO: Cobwebs) the Manussan Empire overthrown in Manussan year 2326, (AUDIO: The Cradle of the Snake) Magnus Greel dying in the 1800s, (AUDIO: The Butcher of Brisbane) and humanity's 50-year war with the Eminence. (AUDIO: The Death of Hope)

Events in the Web that were explicitly recorded in the Matrix included the R101 crashing and all passengers dying, Adolf Hitler becoming Chancellor of Germany (and being alive to continue World War II), Edward VIII abdicating the British throne, German forces invading Poland, the evacuation of Dunkirk, Peladon entering the Galactic Federation, Zephon overthrowing the Embodiment of Gris, Mavic Chen being elected Guardian of the Solar System, Dalek forces assembling on Kembel and being engaged with the Movellans in 4-X-Alpha-4 in 4949, the Cult of Morbius being established, plans for the Doomsday Weapon being stolen by the Master, Chancellor Goth visiting Tersurus, President Romana and Etra Prime being taken by the Daleks and the subsequent Dalek invasion of Gallifrey being repelled by Romana, and a Dalek time fleet being captured in the Time Vortex. (AUDIO: Neverland) Charley Pollard was added to the Web when she saved it, not having died in the crash of the R101 as had been recorded. (AUDIO: Storm Warning, Neverland)
