Realspace

Realspace, known by the Vagaari as crawlspace and usually referred to simply as space by those living within it, referred to the known universe when viewed by an observer traveling at less than the speed of light. Filled almost entirely with vacuum, but containing stars, planets, and other astronomical bodies, it was the dimension within which Humans and nearly all other inhabitants of the galaxy lived.

Other distinct dimensions were hyperspace, through which starships could travel faster than light; subspace, which was utilized for faster-than-light communication; and otherspace, the home dimension of the Charon species.

Traveling in particularly isolated areas of space known as deep space for extended periods of time led to the condition known as deepsick, which caused mental and emotional breakdown.
