Centrifugal Gravity	comment	Simulated gravity created within a spaceship, Space Station, or habitat by spinning it. Currently, science has no way to create gravity where celestial bodies dictate there would be none, or a negligible amount. The only substitute is to otherwise cause acceleration toward stable surfaces. Accelerating in a straight line would constantly use up fuel and produce unwanted velocity, so the most practical solution is to travel in a circular path, causing constant acceleration toward the center. The biggest obstacle to this trope in Real Life is the impracticality of making large enough centrifuges. Your ears are very good at sensing motion and gravity (it's how you balance) and while you're being spun around in a small centrifuge, you're subject to the Coriolis Effect, and so if you happen to turn your head to look left or right, you'd feel nauseous (as many who have ridden in the Gravitron could tell you). The benefits of gravity simply didn't justify the extravagant cost that designing a spinning space station would require. note Especially considering they'd have to design it to handle emergency situations that would necessitate the station to stop moving; in other words, everything would have to be designed to operate in two modes. This would have made the project several hundreds to several thousands of times more expensive than it already would be. NASA and other space programs simply weren't willing to design what would essentially be a multi-billion dollar failure-prone space puke bucket. This being said, a modest reduction in the cost of building a station would make this worthwhile for very large stations that could turn more slowly (which would also not run into the nausea issue as much); however, there is nothing today to make such large stations possible or desirable. Usually appears in hard science fiction; in softer works you can get away with generating Artificial Gravity by throwing enough Applied Phlebotinum at the problem, instead. (Which also tends to be easier to film or animate... Not every production can afford to build a giant centrifuge for its actors to walk around in Ã la 2001!) Some very hard SF works will actively use a necessary side effect of centrifugal gravity: the amount of gravity you feel depends on your distance from the center of rotation. If the spaceship or space station has multiple decks, then objects and people on "upper" (closer to the center of rotation) decks will feel a slightly lower level of gravity than objects and people on "lower" (farther from the center of rotation) decks do. This can be used to produce downplayed versions of Heavyworlders and Lightworlders on the same ship. Examples

However, when not accelerating, the ship can spin up independent centrifuge sections for the (nonexistent) passengers.

Centrifugal Gravity / int_3f20192e	comment	Used as a plot-point in Moonraker. Hugo Drax's secret space station spins on its axis, providing gravity to those inside. James Bond is being held prisoner, but hits the button to stop the station rotating, causing everyone to slam into the walls and then start floating around in zero-gravity. However, Drax's space station was not cylindrical; rather it had a roughly spherical central portion with long appendages sticking out. When it "spins up", gravity is uniform everywhere, and directed towards the "floor" of the main area, when in reality it would vary enormously depending on where in the station you were, and would be directed away from the axis of rotation.

Centrifugal Gravity / int_5bb406f8	comment	This and thrust gravity are the only way humans can generate gravity in The Expanse. Some asteroids (and even Ceres) are also spun up to provide at least a modicum of gravity. The Nauvoo was meant to be a gigantic Generation Ship using an O'Neill Cylinder to provide gravity for agriculture. Its drum is first spun up to provide gravity for the wounded in the "slow zone" as the Behemoth, and it is used for its intended agricultural purpose later as the Medina Station. Unlike most other examples, the books actually do address the issues of coriolis and its Nausea Fuel properties. It specifically mentions that moving closer to the hub of a spinning station causes you to feel less gravity and more coriolis, and that people who aren't used to the sensation often find it quite disorienting and nauseating.

Apparently during the stargate era a Drengin troop transport once had an arm motor jam and toss thousands of troops out into space.

The franchise also consistently shows characters on spaceships and spacestations as being in zero-g, unless the ship/station happens to have a rotating section to provide that gravity. Mobile Suit Zeta Gundam's Cool Ship, the Argama, has residential blocks which can extend on telescoping arms and rotate for this reason.

Centrifugal Gravity / int_9c40134f	comment	Red Planet had a ship that used centrifugal sections for gravity. They take it one step closer to realism by having two sections rotating in opposite directions, as rotation in one direction only would throw the ship off course and end up wasting a lot of fuel to correct. Rotating in one direction will do nothing to alter a spacecraft's course — the Apollo missions all rotated slowly on the way to the moon so as to avoid baking one side in direct sunlight for too long. The reason opposite-direction rotating sections is more practical is to avoid having the central hub of your spacecraft rotate in the opposite direction when your one rotating section is "spun up", or rotate in the same direction due to friction in the bearings. Also, having two counter-rotating sections means angular momentum is cancelled out, making the ship much easier to maneuver.

Bean deduces from emergency exit maps that it's larger than they're told, and there were plans to build more rings connected around it. Subverted as, during the events of that book, they realized the gravity was constant throughout the station but suddenly cut off at the entrance to the Battle Room, implying that it was actually using Artificial Gravity (a technology supposedly reverse-engineered from Bugger technology following the First Invasion). In the prequel Earth Unaware asteroid mining ships have a "fuge" aboard where the crew exercise and small children are raised. The rest of the ship is in microgravity. Interestingly, the same prequel novel also reveals that humanity had already made some progress in Artificial Gravity being used for certain military aircraft (specifically, the HERC developed by Juke Ltd. for New Zealand) as a replacement for rotors. This retcons the origin of Artificial Gravity as a purely human invention rather than technology learned from the Buggers.

It's notable that the non-rotating parts of Discovery and the famous shuttle sequence near the beginning are as being zero gee, through actors walking strangely in "velcro booties", and dangling props from wires, etc. A special rotating set had to be built for this effect. On the other hand gravity in the Moonbase appears to be Earth-normal without explanation. Likewise the Alexei Leonov in the sequel, 2010: The Year We Make Contact, with a segment of the ship designed to rotate when not under thrust to generate pseudo-gravity. In contrast with 2001, less effort is spent to maintain the illusion of zero gee elsewhere, making this a Hand Wave rather than a serious effort at realism (though there is one scene on the zero-g bridge of the Leonov where Dr. Floyd demonstrates his proposal for linking the two ships using floating pens).

Their spin makes docking difficult, as pilots must match the spin or risk crashing into the (wide, but relatively narrow) airlock "slot". In Dangerous, you still need to match rotation until you pass through the airlock, at which point your ship's computers will automatically manage rotation and fire the RCS as-necessary to adjust for this rotation for you... though if you're feeling adventurous (or want to show off) you can easily disable this option and touch down on pads the hard way.

They have a few full size, fits-round-a-star Ringworlds, too, but they're much rarer, since you can get more usable area by using the same mass to build orbitals so most of the Culture regards them as tacky. Notably, this is a setting in which anti-gravity devices are common and reliable, but because the centrifugal force is not the same fundamental force as gravity (even if the net effect ends up the same) those anti-gravity devices will not function on a ring orbital as they would on a planet.
