'''Space''' was a word used to refer to two different concepts relating to the [[universe]]. One referred to [[dimension]]s: space being described by [[Susan]] as the fifth [[dimension]], ([[TV]]: {{cs|An Unearthly Child (TV story)|namedep=An Unearthly Child (1)}}) though the [[First Doctor]] considered space and [[time]] to be the same dimension. ([[AUDIO]]: {{cs|The Cold Equations (audio story)}}) Space was also defined as the [[vacuum]] in the universe, outside of a [[planet|planetary body]]'s [[atmosphere]]. ([[TV]]: {{cs|Oxygen (TV story)}}) This was often known as "outer space". ([[TV]]: {{cs|The Runaway Bride (TV story)}})


'''Space''' was a term used to refer to two different concepts relating to the universe. One of these terms was used with regards to [[dimension]]s; space is, linked to [[time]], with space being the third dimension and time the fourth. ([[DW]]: ''[[An Unearthly Child]]'') The term space was also used to refer to the vacuum that existed in the universe, outside of a planetary body's atmosphere. This was often known as "outer space"{{fact}}.
According to the [[Twelfth Doctor]], space was bent, so [[Earth]] was in any particular direction one chose to look in. ([[TV]]: {{cs|Smile (TV story)}})


==Space travel==
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]]: {{cs|Sleep No More (TV story)}})
Space was a hostile environment existing as a [[vacuum]]. For a vast number of species required a form of [[spacecraft]] to enable them to travel through space.  Some species such as [[Time Lord]]s could survive for a period in the vacuum of space, though they still required [[oxygen]] to breathe. ([[DW]]: ''[[Four to Doomsday]]'')  


Development of the ability to travel through space was regarded as one of the first real steps species took in their planetary and species' development. The [[Time Lord]]s developed space travel when "the universe was half its present size." ([[DW]]: ''[[Genesis of the Daleks]]'') [[Human|Humanity's]] first sojourn into exploring space began in the mid-[[20th century]] with the launch of several [[satellite]]s. ([[EDA]]: ''[[Alien Bodies]]'')
The Twelfth Doctor maintained that [[planet]]s 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]]: {{cs|The Pilot (TV story)}})

Physics tells us that space is interwoven with time, and the two should be considered as either one and the same or directly impacting each-other, as most physicists refer to the structure of existence as 'spacetime'. In traditional, Euclidian thinking, space has only three dimensions (height, width, and depth).  Using the concept of spacetime, existence then has a 'fourth dimension', creating what is called the 'spacetime continuum', which is often another way of stating the 'universe at large'. 


This is, of course, the science-fiction way of looking at things. Generally speaking it's a lot more complicated than that, but whenever the 'space-time continuum' is mentioned, they are generally referring to the Universe in general.
[[Wirrn]] lived in and travelled through space. They could live without fresh [[oxygen]] for several years, but their breeding colonies were terrestrial. ([[TV]]: {{cs|The Ark in Space (TV story)}})


Early ''Doctor Who'' material was also far less technical that it has since become, often using technobabble and inaccurate descriptions under the pretense that most viewers wouldn't understand anyway.{{fact}} For example, in ''[[An Unearthly Child]]'', Susan Foreman states that in addition to the three dimensions used in a math problem, you must also use a fourth, time, and a fifth, which she says is space. However, space is made up of the first three dimensions, meaning that her description of the problem was totally wrong.

Space was a word used to refer to two different concepts relating to the universe. One referred to dimensions: space being described by Susan as the fifth dimension, (TV: "An Unearthly Child" [+]Part of An Unearthly Child, Loading...{"namedep":"An Unearthly Child (1)","1":"An Unearthly Child (TV story)"}) though the First Doctor considered space and time to be the same dimension. (AUDIO: The Cold Equations [+]Loading...["The Cold Equations (audio story)"]) Space was also defined as the vacuum in the universe, outside of a planetary body's atmosphere. (TV: Oxygen [+]Loading...["Oxygen (TV story)"]) This was often known as "outer space". (TV: The Runaway Bride [+]Loading...["The Runaway Bride (TV story)"])

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

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 [+]Loading...["Sleep No More (TV story)"])

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 [+]Loading...["The Pilot (TV story)"])

The physics of space[[edit] | [edit source]]

Space was not as cold as -271.3°C. (TV: Extremis [+]Loading...["Extremis (TV story)"]) There was no pressure in space, nor, of course, oxygen. (TV: Oxygen [+]Loading...["Oxygen (TV story)"]; AUDIO: The Cold Equations [+]Loading...["The Cold Equations (audio story)"]) There was also little, if any, gravity.

Space/vacuum exposure[[edit] | [edit source]]

Main article: Vacuum

Most lifeforms could not survive in the vacuum of space for very long, at least not without a spacesuit, and a good supply of oxygen, among other necessities. (TV: The Moonbase [+]Loading...["The Moonbase (TV story)"], Oxygen [+]Loading...["Oxygen (TV story)"]; AUDIO: The Cold Equations [+]Loading...["The Cold Equations (audio story)"])

According to the Twelfth Doctor, since there was no pressure in a vacuum, one's lungs would explode if they tried holding their breath. Blood vessels would also rupture, and exposed areas of the body would swell up. The boiling point of water was much lower in a vacuum, so one's sweat, saliva and the fluid around their eyes would also boil.

Within 15 seconds, a humanoid exposed to the vacuum of space would lose consciousness, as oxygen bubbles would form in their blood. Within 90 seconds, they would be dead. (TV: Oxygen [+]Loading...["Oxygen (TV story)"]) The Fourth Doctor claimed that so long as one did not attempt to hold their breath, it was possible to survive in the vacuum of space, with no ill effects, for at least 30 seconds. (AUDIO: The Perfect Prisoners [+]Loading...["The Perfect Prisoners (audio story)"])

While Time Lords could remain alive in the vacuum of space for longer than humans, (TV: Four to Doomsday [+]Loading...["Four to Doomsday (TV story)"], The Doctor, the Widow and the Wardrobe [+]Loading...["The Doctor, the Widow and the Wardrobe (TV story)"], GAME: TARDIS [+]Loading...["TARDIS (video game)"]) extended exposure could lead to severe consequences. Prolonged exposure to save his friend, Bill, blinded the Twelfth Doctor, though he did survive. (TV: Oxygen [+]Loading...["Oxygen (TV story)"])

Krynoid pods survived exposure to the vacuum of space by hibernating during voyages through space. (TV: The Seeds of Doom [+]Loading...["The Seeds of Doom (TV story)"])

Wirrn lived in and travelled through space. They could live without fresh oxygen for several years, but their breeding colonies were terrestrial. (TV: The Ark in Space [+]Loading...["The Ark in Space (TV story)"])
