"Sir, the Electrum has reverted to realspace."
―A technician, to Wilhuff Tarkin[1]

Wilhuff Tarkin watches as a group of Imperial weapons technicians are sucked out to die in realspace as punishment for disobeying orders.

Realspace,[1] also called normal space,[2] space-normal to the Chiss,[3] star-space to the Kilji species,[4] or simply space,[5] was the dimension in which all of the galaxy's residents lived. The vast majority of space was a vacuum, a depressurized area devoid of atmosphere. The vacuum of space was fatal to many living organisms without the use of some sort of EVA suit and was unable to sustain fire.[6] Because travel using sublight engines within realspace was slow, sentients found a technological way to access the shadow dimension known as hyperspace. A starship equipped with a hyperdrive would "jump" from realspace into hyperspace, and "revert" from hyperspace to realspace.[1]

Species that could survive in the vacuum of space include exogorths[7] and Cylo's cyborg whale-ships.[8] Neebrays could survive in nebulae, such as the Kaliida Nebula.[9] As well as being able to survive in space, the purrgil were capable of traveling through hyperspace.[10]

Many droids were able to operate in space. Astromech droids were exposed to the vacuum of space when conducting repairs outside the hull of a starship[11] and when inserted into the astromech socket of a starfighter.[12] KX-series security droids could also survive in the vacuum of space.[13] Battle droids, used by the Confederacy of Independent Systems during the Clone Wars, occasionally sat on the outside of ships, such as pod-hunting shuttles.[14]
