Editing Slipspace bubble

{{Status|Canon}}
A '''slipspace bubble''' is a pocket of alternate spacetime enclosed within an envelope of [[slipstream space]].<ref>'''Halo: Ghosts of Onyx''', ''page 381''</ref> Because slipspace is a hyperdimensional spacetime, the contents of the bubble can be manipulated both spatially and temporally relative to the "normal space" of the outside universe.<ref>'''Halo: The Thursday War''', ''page 84''</ref><ref name="ttw205">'''Halo: The Thursday War''', ''page 205''</ref> The science and technology required to create of slipspace bubbles is highly complex and thus out of reach for most civilizations below [[Technological Achievement Tiers|Tier 1]]; only the [[Forerunner]]s and to some extent, the [[prehistoric human civilization|prehistoric humans]] and [[San'Shyuum]], are known to have built such artifacts.<ref name="c121">'''Halo: Cryptum''', ''page 121''</ref>

==Overview==
The basic concept of a slipspace bubble is similar to the "bubbles" occupied by starships when traveling in slipspace. As direct contact with the raw slipstream is harmful to normal-space-based matter, any entities or objects contained in slipspace must use a carefully-tuned quantum field to maintain a survivable volume of "normal" spacetime around them.<ref>'''[[Dr. Halsey's personal journal]]''', ''December 25, 2524''</ref> However, given sophisticated enough technology, the surrounding eleven-dimensional spacetime of slipstream space allows one to alter the temporal and spatial properties of the volume contained within while keeping the bubble completely stable.<ref name="ttw205"/>

In a slipspace bubble, the passage of time can be manipulated both ways in relation to the surrounding universe. In an ''accelerating'' chronological field,<ref>'''Halo: Silentium''', ''page 167''</ref> enormous spans of time may transpire within the bubble, while only moments elapse in realspace. Conversely, in a ''decelerating'' field, time elapses faster; for example, observers in the bubble may experience only days in what amounts to several months in normal space. Similar to the effects of [[Wikipedia:Time dilation|time dilation]], this does not affect the observers' perception of time locally; i.e. individuals in either form of spacetime do not experience the passage of time in a different pace than the other. There is, however, an inevitable and clearly perceptible delay in communications between the interior and exterior of the bubble. Because of the bubbles' transdimensional nature, merely initiating such communications requires special technology.<ref name="g311">'''Halo: Glasslands''', ''page 311''</ref><ref>'''Halo: Glasslands''', ''page 365''</ref>

A [[timelock]], or stasis field, is a decelerating field taken to its logical extreme: no time passes for the occupant while eons may transpire in normal space.<ref name="p366">'''Halo: Silentium''', ''page 366''</ref> Such a field occupies a fractal-dimensioned slipspace and protects its contents from all damage (even from Halo Array's firing)<ref name="Bulletin924">[https://blogs.halowaypoint.com/en-us/blogs/headlines/posts/the-halo-bulletin-9-24-14 '''Halo Waypoint''' - The Halo Bulletin: 9.24.14'']</ref> inflicted from outside the field; any incoming energy is reflected by the fractal dimensions and scattered in the field's surroundings as thermal energy and high-energy radiation.<ref name="p331">'''Halo: Primordium''', ''pages 331-332''</ref>

In addition to the ability to manipulate time, slipspace bubbles allow the compression of immense masses and volumes into a comparatively tiny space. This was demonstrated by [[Trevelyan|Shield World 006]], a [[Astroengineering|megastructure]] 300 million kilometers in diameter, encased in a slipspace bubble of compressed dimensionality only 23 centimeters in diameter in normal space.<ref name="g230">'''Halo: Glasslands''', ''page 230''</ref>

==Applications==
The Forerunners were known to have developed a plethora of uses for slipspace bubbles.

*The [[shield world]] [[Sarcophagus]], a full-sized [[Dyson sphere]] massing 1.37 [[Wikipedia:Solar mass|solar masses]], existed in a compressed slipspace bubble of both time and space, only 23 centimeters in diameter on the outside.<ref name="g230"/> Before being transitioned into normal space, there was a noticeable time differential between the interior and exterior of the bubble: several days passed for the human survivors in the sphere, while over two months elapsed in the surrounding universe.<ref name="g311"/> The inhabitants later had the shield world returned to its slipspace bubble as a form of protection against the [[Created conflict]].<ref>'''[[Halo: Legacy of Onyx]]''', ''page 317''</ref>
**The shield world's interior was home to a series of concentric bubbles,<ref>'''Halo: Glasslands''', ''page 306''</ref> in some of which time elapsed in a different pace than the rest of the sphere. [[Lucy-B091]] fell into a bubble containing [[Garage (Shield World 006)|a hangar facility]], experiencing only hours whereas days passed to the other human survivors in the sphere's primary timeline.<ref>'''Halo: Glasslands''', ''page 280''</ref>
**The [[Huragok]] based on Trevelyan were capable of creating rudimentary temporal-manipulated slipspace bubbles. The [[ONI]] researchers in the facility used these bubbles to grow crops of the [[Sangheili]] grain [[irukan]] at a much more rapid rate than normally possible as part of a stratagem to create a [[bioweapon]] to be unleashed against the Sangheili.<ref name="ttw205"/>
**When Sarcophagus is returned to its bubble in [[2558]], the shield world takes with it the three planets that had fallen into its orbit when Sarcophagus was returned to real space in 2553.<ref>'''[[Halo: Legacy of Onyx]]''', ''page 403''</ref>

*The original twelve [[Halo Array|Halo installations]] were capable of locking portions of the ring, or the entirety thereof, into pockets of time-suspended slipspace fractal stasis, also rendering the sections invulnerable to damage. However, this also consumed enormous amounts of energy.<ref name="p331"/>

*[[Slipspace field pod]]s were Forerunner stasis chambers in which time was slowed to a standstill for the occupant, freezing them in time and thus protecting them from harm.<ref>'''Halo: Ghosts of Onyx''', ''pages 335-337''</ref>

*Forerunner family [[Durance]]s, used to contain the [[Mind transfer|extracted final impressions]] of a deceased individual, were traditionally placed into time-locked stasis.<ref>'''Halo: Cryptum''', ''page 47-48''</ref>

*The [[timelock|time bolt]] was a time-locked stasis field system created by the prehistoric [[San'Shyuum]] [[Human-San'Shyuum alliance|allied]] with [[Prehistoric human civilization|humanity's interstellar empire]]. This stasis chamber was used to contain the [[stasis capsule]] of the [[Precursor]] intelligence known as the [[Primordial]].<ref name="c121"/>

*A "reverse timelock" was used on [[Installation 07]] by the [[IsoDidact]] to detain and execute the Primordial. When activated, the field forced the being to experience a billion years in moments and led to its complete disintegration due to entropy.<ref name="p366"/>

*The [[Ur-Didact]]'s second [[Cryptum]], locked in the core of [[Requiem]], was encased in a protective slipspace stasis bubble which shielded the Didact from the Halo Array's firing.<ref name="Bulletin924">[https://blogs.halowaypoint.com/en-us/blogs/headlines/posts/the-halo-bulletin-9-24-14 '''Halo Waypoint''' - The Halo Bulletin: 9.24.14'']</ref>
