Black hole

Black Holes are the cores of collapsed stars, a place where gravity is so great that nothing, not even light, can escape its pull.



Black holes and the Time Lords
Thought to occur naturally by human astrophysicists, the Doctor stated that the Time Lords invented black holes. (DW: The Satan Pit)


 * We do not know if he meant this literally or as a figure of speech.

Omega and Rassilon destroyed the star Qqaba (DWM: Star Death) as an energy source powerful enough to enable time travel. Omega, thought dead, survived his journey through this black hole, although he was trapped within it. He was also able to shape matter within it to his will. (DW: The Three Doctors, Arc of Infinity)

Rassilon brought back either a black hole or its singularity, the Eye of Harmony back to Gallifrey. (DW: The Deadly Assasin)

The Doctor's TARDIS had the power both to resist the pull of the black hole and also to tug the Walker Expedition rocket out of the gravitational field of K37 Gem 5 (DW: The Satan Pit).

Black holes and other species

 * An arch-criminal from the planet Nefrin, Brimo, sentenced to remain alive forever in an eternity capsule, found herself inside a black hole when Nefrin's sun collapsed upon itself. Much like Omega, she found herself in a mutable world shaped by her imagination and drained energy from the universe outside it. (DWM: The Time Witch)


 * The Nimons based most of their technology on artificial black holes, especially for long distance transportation. (DW: The Horns of Nimon)


 * In 2986, the Black Hole of Tartarus presented a hazard to spacecraft. (DW: Terror of the Vervoids)


 * The ancient Disciples of the Light fixed a planet in stationary orbit around a black hole. The Doctor, before learning of this, regarded the planet's fixed orbit as scientifically impossible. Both the black hole and the planet served as a prison in which to confine the Beast. (DW: The Impossible Planet, The Satan Pit)


 * In 2006 or later, an experiment in Switzerland created an artificial black hole, which K-9 then spent a year and a half trying to stabilize. (SJA: Invasion of the Bane).

Minor references

 * Before his death, Eugene Jones planned on attending a lecture entitled "Black Holes and the Uncertainty Principle" at the University of Wales, Aberystwyth with his friend Gary. Having found a flyer for the lecture in Eugene's room, Gwen Cooper showed up there, hoping to run into Gary there. (TW: Random Shoes).
