In physics, a '''gravity well''' is the [[wikipedia:gravitational potential|gravitational potential]] field around a massive body (a particular kind of [[Wikipedia:potential well|potential well]]). Physical models of gravity wells are sometimes used to illustrate [[wikipedia:orbital mechanics|orbital mechanics]]. Gravity wells are frequently confused with [[Wikipedia:general relativity|general relativistic]] [[Wikipedia:embedded diagram|embedding diagrams]], but the two concepts are unrelated.<ref>'''[[Wikipedia:Gravity Well|Wikipedia]]'''</ref>

Large objects can generate gravitational fields that extend far into space. Consequently, human [[slipstream space|slipspace]] navigation is hindered by the effect these gravity wells have upon the quantum field of the Slipstream, and ships must make their calculations away from such factors. With an increased resolution of the Slipstream, such as that possessed by [[Forerunner]] and, consequently, [[Covenant Empire|Covenant]] slipspace matrices, calculations can be made to compensate for this effect.<ref>'''[[Halo: First Strike]]'''</ref>

The [[Forerunner]]s, particularly the [[Promethean]]s, were known to use gravity well technology as a form of [[wikipedia:Tractor beam|tractor beam]], in order to keep certain starships from escaping by pinning them down in place. The [[John-117|Master Chief]] was forced to take a [[Mobile Anti-Aircraft Weapons Platform M510 Siegework/Ultra-Heavy|Mammoth]] along with a contingent of [[SPARTAN-IV Program|SPARTAN-IV]]s and some [[UNSC Marine Corps|Marines]] in order to destroy several of these such devices in order to allow the {{UNSCShip|Infinity}} to escape [[Requiem]].<ref> '''[[Halo 4]]''' level ''[[Reclaimer (level)|Reclaimer]]'' </ref> 

==Gravitational slingshot==
Gravitational slingshot refers to use of the relative movement and gravity of a celestial body to alter the path and speed of a spacecraft. This maneuver is commonly known as "slingshot orbit", and has been used in numerous occasions. [[Preston Jeremiah Cole|Preston Cole]] was known to be adept in using a planet's gravity well to his advantage in space combat.<ref>'''[[Halo: Evolutions - Essential Tales of the Halo Universe]]''', "[[The Impossible Life and the Possible Death of Preston J. Cole]]"</ref>

*In ''[[Halo Wars]]'', the gravity well of an artificial star within [[Shield 0459|a small Shield World]] was used to accelerate the {{UNSCShip|Spirit of Fire}} to safety after creating a chain reaction and sending the star into its [[supernova]] state.<ref>'''[[Halo Wars]]'''</ref>
*In ''[[Halo: First Strike]]'', [[Cortana]] used the gravity well of [[Basis]] to slingshot the [[John-117|Master Chief]]'s [[GA-TL1 Longsword|Longsword interceptor]] around it and simultaneously save survivors from [[Installation 04]].
