Space-time continuum

The Time Vortex was the structure of the space-time continuum. (PROSE: The Crystal Bucephalus)

N-Space, which was the prime universe according to the Doctor, was comprised of eleven dimensions, including those comprising the space-time continuum. (PROSE: Parasite) The Doctor's TARDIS herself stated that she was an eleven dimensional being that existed across all space and time, (TV: The Doctor's Wife) while the Fifth Doctor referred to the ship as having an internal continuum. (AUDIO: The Butcher of Brisbane)
