Otherspace

This is a list of the known dimensions of the First Contact universe, many are used for FTL travel, while others serve a more ominous purpose.

Terran scientists have established an entropic hierarchy of the multiverse:


 * Hyperspace
 * Jumpspace
 * Hellspace
 * Stringspace
 * Realspace
 * N-Space
 * Subspace
 * Deadspace
 * Darkspace

Those "above" Realspace are used for superluminal travel, the ones "below" are used for other things.

Dark Matter Seas
An "ocean" of proto-matter that seems to interact with or be a path to deadspace.

Darkspace
A universe of very high entropy, ranked "below" Deadspace in the Terran hierarchy.

Deadspace
Deadspace borders realspace, it is known to be used by Daxin Freeborn and the Antaeus Fleet for refit and repair.

"There was light years between those two particles. Entire light years of purple dead space with no depth, no width, no length, no time, no laws we are familiar with."

"A stillborn dimension where the Big Bang was a whimper."

"So are the things in deadspace really small, or are the particles really big?"

"Yes"

Hellspace
An hyperatomic plane originally used for FTL travel by the Mantids and their Precursor machines. The Lanaktallans damaged it somehow. There may be entities still living there.

Unshielded jumps through Hellspace turns the jumpee into something dependent on nearby observers. Similar to the "observation changes result" weirdness of observation of quantum phenomena, but... The probability collapses to a point, but it's "corrected" to the worst possible result.

Hyperspace
A plane that sits above jumpspace, also containing bands. Some things sitting in hyperspace can cause "bulges" that impact the jumpspace bands. The upper bands will tear apart VI's and AI's.

Jumpspace
Contains higher and lower bands, determines speed of travel. Lower bands can be inhospitable to AIs because they border Hellspace, while upper bands are faster and dangerous to AIs. Large enough objects can create a "jumpspace bulge" that can affect other nearby ships in jumpspace.

N-Space
Used by the Atrekna for temporal travel.

Realspace
4-dimensional space that most recognizable matter occupies, bordered by multiple other dimensions.

Stringspace
Another dimensional space that borders realspace, separated by dimensional foam. Likely related to super string theory.

Subspace
Used by the Terran Confederacy for communication beacons, sub-light munitions and subluminal drives. The massive gravitational anomaly that is the Combined Rigel System means that FTL drives cannot be used for 9 light days around the system, only subspace drives to a maximum of 0.7c can be used.
