Template:SeeWikipedia In physics, a gravity well is the gravitational potential field around a massive body (a particular kind of potential well). Physical models of gravity wells are sometimes used to illustrate orbital mechanics. Gravity wells are frequently confused with general relativistic embedding diagrams, but the two concepts are unrelated.[1]
Large objects can generate gravitational fields that extend far into space. Consequently, human 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 slipspace matrices, calculations can be made to compensate for this effect.[2]
Uses
Gravity wells have been used to slingshot ships around celestial bodies in various occasions in the Halo universe.
- In Halo Wars, The gravity well of an artificial star within a small Shield World was used to accelerate the UNSC Spirit of Fire, unable to use its FTL reactor, to safety after creating a chain reaction and sending the star into its supernova state.[3]
- In Halo: First Strike, Cortana used the gravity well of Basis to slingshot the Master Chief's Longsword around it and simultaneusly save survivors from Installation 04.
