Subspace

A **Subspace**, sometimes referred to as a **Subrealm**, **Semi-plane**, or **Endcon**, is an isolated space of matter contained within Planes. Subspaces typically come about as a result of crippling damage to spacetime, or if there is too much matter contained/produced within an individual Plane, causing a tear in space and resulting in small pockets of empty matter being created within Planes, branching off and diverging out of the Plane into Subspaces. Subspaces can also be created manually by separate entities, such as Subspace 15, which was created and is managed by Soggy Cat as a private abode.

Subspaces are commonly tethered to their original Plane sections via loose strands of tubular matter, limiting the potential for implosion via outside pressure or drifting. This tethering typically results in Plane-Subspace traversal, an outcome which can sometimes result in unintentional spatial travel, but can also allow Subspaces to be used as "checkpoints" in Planes.

## Etymology

The term "Subspace" is derived from Latin prefix *sub-*, meaning "a subordinate or secondary part of something else", and *-space*, as Subspaces are commonly housed within internormal sections of spacetime itself.

The term was coined in 1988 by Andrew Fey (known more commonly as Mr. Bones) during his studies into the Penta-Dimensional Plane and it's properties.

## Composition

Subspaces are typically composed of excess matter, isolated atoms, energy, and miscellaneous particles. These bundles of matter and energy can combine in different ways, as described by the **Andrews-Hazel Subspace Index**, a catalog created to assist with the identification and classification of Subspace types, created in 1996 by American and Russian scientists Andrew Fey and Isaac Hazeltov.

### **Andrews-Hazel Subspace Index**

***Type 1 Subspace - Typically composed of an extraordinarily dense and extensive mass of collected energy and matter, almost always completely inhospitable and chaotic.***

***Type 2 Subspace - Loose, organized collection of matter and energy, typically sorted into solid, repetitive bundles of active matter. Less chaotic and more comprehensible than a Type 1 Subspace, with a slightly higher chance of hospitability depending on the solid matter it is composed of.***

***Type 3 Subspace - Very high chance of hospitability and survivability. Strict, uniform collections of energy, typically sorted into recognizable shapes and ideas. However, this room for comprehensible matter leaves more ability for harmful substances to successfully be naturally synthesized within the Subspace. Less than 4% of all Type 3 Subspaces are created without intervention or assistance from an outside entity.***

Less than 0.8% of all Subspaces exist as Type 3s, usually materializing as chaotic, strained masses of matter.

## Recurrence

Subspaces are incredibly common in general, typically forming in collections of 8-900 million per section, depending on the size of the section, density, population, and gravity of matter. The Penta-Dimensional Plane, for example, is estimated to be home to more than 800 million individual tethered Subspaces, with less than 10,000 being officially discovered and documented, and the majority of all recorded Subspaces existing as Type 1 and Type 3.

## Discovery and Research

Subspaces were discovered and properly documented almost simultaneously with the discovery of the Penta-Dimensional Plane in the late 1970s, with research being completely undertaken in the early to late 90s by BonesTech, Incorporated, with figures such as Andrew Fey and Isaac Hazeltov being leaders in many studies. Documented Subspaces are commonly organized numerically, typically using "S" as an abbreviation followed by a number in order to designate consecutive value, in order of discovery *(i.e. S56, S2467, S9876)*.

## Travel

Travel between Subspaces is extraordinarily difficult, typically requiring a near-impossible amount of speed in order to allow a break of force on the object being moved to and from a Subspace, a process which cannot be done reliably on a living subject without almost always lethal results. Subspace travel has only been successfully completed three times on record, the first being the successful travel to Subspace 76 by the **SS Corlod *High Speed Travel Vehicle* *(HSTV)***, a trip which resulted in the death of all crew onboard, with the only recovered data being molecular information and a single photograph. The second being the miraculous and sudden transport to Subspace 15 of American physicist and polymath Mr. Bones, a feat which is doubted by many due to it being accomplished within the participant's mind, and being directed by an entity other than the crew. The third, the only genuine trip resulting in all crew returning unharmed, was a feat accomplished by Mr. Bones in November of 2023 via strapping 17 jet engines on a 2007 Honda Civic moving prograde with a modified engine and superheated tension coils on the wheels.

Bones was the only crew onboard, and, during his travel, would describe the experience as "harrowing", matter within and around the car melting and being melded by outside force and the continuous meshing of outward matter being applied directly onto the vehicle at speeds thought to be completely impossible of up to almost **13 billion x *c*** *(3,897,301,950,000 km/s)*, the car being subjected to an almost infinite source of energy. During the trip, the car would reach record speeds, being freed from gravitational and relational constraints, defying the laws of physics and the theories of Einstein altogether, being launched at extreme speeds into a previously unknown Type 1 Subspace, now designated *S9987*. Forces impossible to represent via simple numerical values were exerted upon the car, however, through unknown means, the car returned almost unscathed, apart from the complete liquification of the windshield and dashboard and the fact that the wheels were covered in a microscopic biological lifeform unknown to science.

The trip lasted almost 15 minutes, with Bones returning back to Earth safely, apart from having minor trauma.
