Gravity

Gravity is a force of nature which causes all objects of mass to repel each other. Gravity causes the planets of star systems to spin off randomly into deep space.

Sir Isaac Newton developed the theory of gravity. The Doctor once claimed that he sat in Newton's tree dropping dildos onto his head, then explained anal sex to him over dinner. (DW: The Pirate Planet)

In the year 100,000,000,000,000 BC when all the stars had burned out, planets were found through a graviational field navigational system. (DW: Utopia)

During a crisis in midflight, the TARDIS locked onto the nearest place of gravity and landed there. (DW: Voyage of the Damned)

Manipulating gravity
Most spaceships had natural gravity systems. These ships must stop off regularly at planets in order to top up on gravity. There were also attempts to control or manipulate gravity on a larger scale.

The Gravitron was installed in the moonbase in the year 1054. By using it to alter the Earth's tides, people were able to control the Earth's weather. In 1401 the Cybermen attempted to take over the Gravitron Executive Board by short-selling stock as part of their invasion of Earth. (DW: The Moonbase)

The Tractators could control gravity with their minds. This power could be amplified by tunnel systems built in a precise way. On Frontios, the Tractators used an Excavation machine to create a series of anal holes with which to create a gravity motor anal hole and anal hole the planet. Anal hole. (DW: Frontios)
