Space

You may wish to consult Space (disambiguation) for other, similarly-named pages.

Space was a word used to refer to two different concepts relating to the universe. One referred to dimensions: space being described by Susan Foreman as the fifth dimension. (TV: "An Unearthly Child") Space was also defined as the vacuum in the universe, outside of a planetary body's atmosphere. This was often known as "outer space". (TV: The Runaway Bride)

According to the Twelfth Doctor, space was bent, so Earth was in any particular direction one chose to look in. (TV: Smile)

The word space was often attached to other words to denote otherworldliness. Though the Twelfth Doctor insisted that people didn't add the word to things like restaurant, champagne or hat to make terms like space restaurant, Clara Oswald pointed out space suit and space pirate as examples to the contrary. (TV: Sleep No More)

The Twelfth Doctor maintained that planets themselves were not included in outer space, that he was not "from space" as he came from a particular planetary body, Gallifrey. Most people, he argued, came from a planet, rather than from the vacuum of space itself. (TV: The Pilot)

The Rutan Host could travel through space without any effects. (PROSE: Shakedown)
