Time Vortex
The Time Vortex (sometimes just called 'The Vortex') is the place through which the TARDIS travels. With the Time Vortex, someone could conceivably reach any point in time or space or even other universes (except parallel universes, because after The Last Great Time War they became impossible to visit due to the absense of the Time Lords). Also, the Time Spiral could cause some problems. It is unkown where the Time Vortex is located, but it could be outside of the universes, allowing access to them. Some, but not all, other space-time machines use the Vortex, such as the vessels used by the Daleks (DW: The Chase) or Jack Harkness' vortex manipulator.
Native life in time vortex includes the Reapers (DW: Father's Day) and the Chronovores. (DW: The Time Monster). The Bad Wolf entity also seems to be linked to the Time Vortex; when Rose Tyler was infused with the entity she was also infused with Vortex energy, and the entity also can spread the Bad Wolf meme through time and space, suggesting some power over time.
Mrs Wormwood detected artron energy in a body scan of Sarah Jane Smith, using it to conclude that she had traveled in the Vortex. (SJA: Invasion of the Bane)
- It is not known if she had residual artron energy as the result of travel through the Vortex itself or as a result of her means of travel, namely the Doctor's TARDIS.
This may or may not have a connection with vortex energy, which Rose Tyler and the Doctor absorbed into their bodies, the former from looking into the Heart of the TARDIS, the latter from orally absorbing it from Rose. In both cases, the energy, which resembled bright white-gold wispy light, threatened to destroy their cellular structure, much like radiation. The Doctor had to regenerate in order to survive. (DW: The Parting of the Ways). However, even the Doctor's body contained some traces of vortex energy, which he exhaled (it is possible that this was in fact regenerative energy). (DW: Children in Need Special, The Christmas Invasion). The energy gave Rose the power to destroy the Dalek fleet and resurrect Jack Harkness. (DW: The Parting of the Ways).
Something resembling vortex energy was emitted from the TARDIS's Eye of Harmony and resurrected Grace Holloway and Chang Lee. (DW: Doctor Who)
- Considering its appearance and life-giving properties, it is reasonable to assume that this was vortex energy. It is also reasonable to assume that the TARDIS had greater control over this energy than Rose did and did not make Grace and Lee immortal like Jack. However, this is not certain.
The Doctor used the timey-wimey detector to trace the arrival of Billy Shipton, who had travelled back through time to 1969. This device may have been designed to detect the presence of vortex (or artron) energy. (DW: Blink)
TARDISes are alive, so the Time Vortex probably is as well. If it is then it will grow and change - that might explain the different looks throughout the seasons/series.
Behind the Scenes
- The Time Vortex is seen in the opening and closing credits from Series 1 (2005) to the present. Whether these opening credits will be used for Series 5 has yet to be revealed.
- The 2010 series introduces a new redesign of the time vortex - more blue and fluid, similar to an updated Tom Baker-era vortex. [1]
- Strangly The TARDIS seens to spin slower in the Blue Vortex than in the Red Vortex, where it spins as if it is out of control. The TARDIS in the blue vortex is spinning as if it's in a blueshift where it progress backward through time slowly or at a level speed. The red vortex represents the redshift in which the TARDIS has to be at a certain place in time really quickly as shown in The Lazarus Experiment, the following story 42 and in Utopia.
- The Doctor Who Confidential page of the episode Doomsday stated that the red vortex indicates travel forward in time and blue vortex indicates travel backward in time, though further details were not revealed.
