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.
- 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 though he was trapped though which he also shaped to his will. (DW: The Three Doctors)
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
The Nimons based most of their technology on artificial black holes, especially for long distance transportation. (DW: The Horns of Nimon)
The Disciples of the Light fixed a planet in geostationary orbit around a black hole. The Doctor regarded this as scientifically as impossible. Both the black hole and the planet a 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).
Notes
- Some scientists believe that there is a black hole in the center of most galaxies, including the Milky Way. Whether this is true in this universe is unknown.
