Personspace, or Human Space, was the term given to how much of the Mutter's Spiral had been explored by humans.
By the 22nd century, "personspace" distinguished between physical space itself and the dimension-puncturing Interstitial Mass Transit System run by the Sol Transit System, considered to have "stopped the planets in their ancient rotation." (PROSE: Transit)
Human Space included colony placements along space lanes, (AUDIO: Three's a Crowd) and those outside of Human Space tended to use Terran Mean Time for convenience, the date being three-quarters of a century before Earth. (PROSE: Just War)
In 4000, Dalek space in the galaxy was almost as large as that occupied by Earth, its colonies, and its allies. (PROSE: Mission to the Unknown)
