'''Artificial gravity''' is employed by the [[United Nations Space Command|UNSC]], [[Covenant]] and the [[Forerunner]]s, to generate gravity of varying strengths in an otherwise zero or low-gravity environment.<ref>[[Wikipedia:Artificial gravity#Centrifugal Force|'''Wikipedia''': Artificial Gravity'']]</ref> | '''Artificial gravity''', also known as '''contragravity'''<ref name="WF86">''[[Halo: Warfleet – An Illustrated Guide to the Spacecraft of Halo|Halo: Warfleet]]'', Weapon-Ships - p.82-83</ref>, is employed by the [[United Nations Space Command|UNSC]], [[Covenant]] and the [[Forerunner]]s, to generate gravity of varying strengths in an otherwise zero or low-gravity environment.<ref>[[Wikipedia:Artificial gravity#Centrifugal Force|'''Wikipedia''': Artificial Gravity'']]</ref> | ||

A number of UNSC ships employ rotating sections of the hull to provide centrifugal force on the interior of the hull to allow comfortable movement in "gravity." On certain ships, the rate of rotation can be adjusted, allowing more or less gravity, and a number of other ship classes, such as {{Class|Halcyon|light cruiser}}s, also used rotating sections before the introduction of more advanced gravity plating.<ref group="note">Realistically, the rate of spin for many of the smaller UNSC ships would have to be quite low (2 RPMs or lower) to prevent the crew from getting dizzy and nauseated due to the Coriolis effect. This means that the "gravity" produced by the rotating sections of most UNSC ships would be well below 1g. Space stations and colonies at least a mile in diameter would likely be able to produce 1g. However, even the relatively small rotating section that constitutes the gym of the carrier ''Atlas'' is said to be able to simulate gravity up to 2g without causing nausea. Although this could be a simple oversight, it is possible that the nauseating effects of spin are mitigated through unknown means, possibly by using anti-gravity emitters in tandem with the rotating carousel system. This style of artificial gravity also fails to explain how an [[elevator]] can run through and traverse out of the rotating sections, something that occurs multiple times in the novels.</ref> | A number of UNSC ships employ rotating sections of the hull to provide centrifugal force on the interior of the hull to allow comfortable movement in "gravity."

===Covenant=== | ===Covenant=== | ||
Almost all Covenant vessels employ some sort of artificial gravity mechanism that does not involve rotating hull sections or acceleration. Instead, their method allows for the generation of actual gravity.<ref group="note">It has been speculated that the Covenant may use [[Wikipedia:Diamagnetism|diamagnetism]], but this is very unlikely: though there would be no known adverse health effects, it would mean that the entire ship would have to be made of non-magnetic materials, have heavily shielded electronic equipment and the crew would not be able to use anything made of metal. The use of ultra-dense materials which generate their own gravity has been suggested, but this would make the ship incredibly heavy and massive. Considering the UNSC still use some form of reaction/rocket propulsion, it seems rather unlikely that this would be the case.</ref> | Almost all Covenant vessels employ some sort of artificial gravity mechanism that does not involve rotating hull sections or acceleration.
