==Centrifugal force==
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 [[Halcyon-class 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>
