The curvature of spacetime inside slipspace is affected by the gravity wells of planets outside the slipstream, leading to the formation of [[transit point]]s that allow for easier access into slipspace. These transit points like together to form slipspace "routes", providing faster and more optimal travel time than ordinary slipspace travel.<ref name="SS22"/> The Forerunners employed these navigation techniques heavily, in a process referred to as a "Rational Journey".<ref name="WFG">''Halo: Warfleet'', Glossary - p.90-92</ref>/>

The [[Gravemind]] was able to use the {{UNSCShip|In Amber Clad}} to make a successful precision jump into ''[[High Charity]]''. This may be due to an improvement on the ship due to the recent capture of Covenant Slipspace technology, the Gravemind adjusting it or possibly using [[Installation 05]]'s [[teleportation grid]] or related systems to move the ship.<ref>'''Halo 2''', campaign level ''[[Gravemind (level)|Gravemind]]''</ref> Cortana was able to jump the Covenant flagship ''[[Ascendant Justice]]'' into slipspace inside the atmosphere of the gas giant [[Threshold]] following the [[Battle of Installation 04]], a feat previously thought impossible even by the Covenant.<ref>'''Halo: First Strike''', ''pages 80, 87''</ref> Following the Human-Covenant War, a number of UNSC ships, such as the {{UNSCShip|Infinity}}, have been fitted with Forerunner drive technology, granting them near-perfect jump accuracy in addition to far greater velocities.<ref name="ttw247"/>

The Covenant employ a device known as a ''[[kelguid]]'' to plot slipspace, reverse-engineered from similar Forerunner equivalents. Covenant ''kelguid''<nowiki>'</nowiki>s visualise slipspace as appearing like a "dinner of spaghetti and meatballs that had entered zer-g and floated up off the plate". In this visualisation, the "spagehetti" represents the curvature of space-time and the "meatballs" represent gravity wells of various sizes. Where the "spaghetti" bends so tightly as to touch itself, this creates a connection point that can be employed as a [[transit node]] by a suitable vessel.<ref name="SS22">''Halo: Silent Storm'', Chapter 22</ref>


As a testament to the Forerunner's understanding of slipspace, [[Installation 00]], located far distant from the galaxy itself, is able to locate vessels within the galaxy and spontaneously open precision slipspace portals between itself and locations in the galaxy. The {{UNSCShip|Spirit of Fire}} was drawn to Installation 00 in such a manner after drifting in space for 28 years without a slipspace drive.<ref>'''Halo Wars 2''', campaign level ''[[The Signal]]''</ref>

Gravitational fields of significant size, such as those generated by a planet, affect the superfine quantum filaments that a slipspace drive must use to calculate an entry point to the slipstream, and UNSC calculations are unable to offset this effect.<ref name="numbers">'''Halo: First Strike''', ''page 85''</ref> Covenant drives, in turn derived from Forerunner technology, have a much higher resolution of the filaments, and use more accurate calculations, and though the Covenant do not use this ability, are capable of making slipstream transition in and out of a planet's gravity well.

During the [[Battle of Mombasa]], the [[Prophet of Regret]] used this newfound knowledge to transition into slipspace while directly over [[New Mombasa]] in Earth's gravity well, damaging the city and causing the weakening and eventual collapse of the [[New Mombasa Orbital Elevator|orbital elevator]] there.<ref>'''Halo 2''', campaign level ''[[Metropolis]]''</ref> These events show that, while the Covenant often cannot innovate their own solutions, they are quick to adopt any practice that increases their combat prowess.

The effect of a gravity well on the curvature of space-time inside slipspace often allows for the right conditions to form to allow for the formation of a [[transit point]], allowing easier access to slipspace than may otherwise be possible.<ref name="SS22"/>

Slipspace travel is also dangerous due to the high level of [[radiation]] encountered during the trip, which can be extremely hazardous to the crew. This is negated by the use of [[lead foil]] in UNSC ships, which absorbs the radiation. Fissile materials also emit radiation, specifically [[Čerenkov radiation]], upon exiting slipspace; this is not harmful to humans, however it does make emerging from slipspace very noticeable. It is not known how the Covenant deal with radiation, but it is presumed that either they also utilize a shielding material, or with their improved slipspace technology and [[energy shielding]], it does not affect them at all.<ref name="Halo page 13">'''Halo: Ghosts of Onyx''', ''page 13''</ref> In addition, slipspace travel generates a great deal of static electricity on the ship's hull.

Since the Slipstream is constantly shifting, and its laws of physics are different to our own, the magnetic coils of Slipspace drives drift out of phase when entering and leaving a Slipspace field, requiring constant maintenance. During the [[2490]]'s, technicians had to manually repair Slipspace drives, exposing themselves to the Slipstream and occasionally suffering injury, death or simply disappearing.<ref>'''Halo: Ghosts of Onyx''', ''page 146''</ref> Mechanical failures like [[Slip Termination, Preventable]], or STP, can also occur with Slipspace drives, usually resulting from poor maintenance.<ref>'''Halo: Contact Harvest''', ''page 24''</ref> An improperly mounted Slipspace drive can also result in catastrophic accidents, as was the case with a colony ship ''en route'' to the [[Cygnus system]] in the mid-2550s: as a result of a maintenance failure, the drive tore the ship apart, transporting half of it into an unknown location. During the [[Fall of Reach]], the UNSC intentionally recreated the conditions of this accident to destroy a [[Covenant supercarrier]].<ref>'''[[Halo: Reach]]''', campaign level ''[[Long Night of Solace (level)|Long Night of Solace]]''</ref>

In rare cases, various types of anomalous phenomena occur in slipspace. These may be caused by specific artifacts or devices. The effects of these anomalies are diverse, but often harmful. The [[Forerunner crystal]] found on Reach was capable of creating a distortion in Slipspace, but it also generated massive amounts of radiation. In November 2552, the slipspace transition of the [[Forerunner Dreadnought]] caused an anomaly within the dimension [[YED-4]].<ref>'''Halo: Ghosts of Onyx''', ''pages 198-199''</ref>

Slipspace has been used as the basis for some (although not all) forms of faster-than-light communications system, enabling communication across the vast distances of space in reasonable timescales. First utilized by the Forerunners, such technologies were later appropriated for use by the modern civilizations of the Covenant and humanity.

The Forerunners had developed a great deal of applications for the slipstream. These included the ability to create [[Slipspace bubble|bubble-like enclosures of slipstream space]], in which the flow of time could be manipulated or stopped altogether while keeping the contents of the bubble either visible or invisible in normal space. The Forerunners were also capable of containing these bubbles of alternate space-time within one another.<ref>'''Halo: Glasslands''', ''pages 306, 311''</ref> These bubbles could be used to store considerable masses and volumes in slipspace stably for thousands of years and potentially for all of time, and to transition matter from normal space to the inside of a construct in slipstream space without requiring the construct to transition back to normal space. The same technology was utilized in [[slipspace field pod]]s that were essentially a Forerunner equivalent of [[cryo-chamber]]s, effectively preserving a living organism inside a slipspace field. Slipspace bubbles were also employed in a type of Forerunner prison cell in which the passage of time could be manipulated so that a period of a billion years would pass inside the field, while only seconds had transpired in normal space.<ref>'''Halo: Primordium''', ''page 366''</ref>

In addition, the Forerunners had the ability to construct weapon systems that could fire into slipspace and affect targets in normal space or within slipspace. This is demonstrated by the [[Line installation]]s of the [[Maginot Line|Jat-Krula boundary]], which were capable of intercepting ships in slipspace.<ref name="blood">'''[[Halo: Blood Line]]''' - ''[[Halo: Blood Line Issue 1|Issue 1]]''</ref> In its [[Battle of the Maginot Sphere|final battle]] against [[Mendicant Bias]], the Forerunner AI [[Offensive Bias]] used slipspace ruptures generated by its warships to warp the laws of physics around them and tear Mendicant's ships apart.<ref>'''Halo 3''', ''[[Terminal/Halo 3|Terminal 6]]''</ref>
