From the old West End Games D6 Roleplaying Game (Second Edition) supplement Death Star Technical Companion, Chapter Two: Technical Specifications, p. 16, right column: Gravity within the battle station was handled by omni-directional gravity boosters built into the decks, walls and ceilings. These gravity boosters changed orientation as easily as flipping ...

According to the Star Trek: Deep Space Nine - Technical Manual the rotation was driven by four factors: To control the rotation imparted by the processes of docking and undocking spaceships. To control the additional centrifugal force imparted by transferring ore from the processing centre (at the middle of the station) to docked ships at the outer pylons. ...

I found an article on SerenityVerse entitled "Serenity Ship Specifications and Plans". It states: The Firefly class ships [sic] gravity comes from a rotating ring just aft of the ships [sic] midsection. It produces a gravity field using the “Peristere Principal" [sic], that also acts as an momentum dampener to allow passengers more freedom of movement ...

This is really more of a physics issue, see my answer on the physics stack exchange here--objects away from the ground in a rotating cylinder will still appear to be subject to gravity, their inertial paths will naturally cause them to come crashing to the inner surface of the cylinder (similarly, see this page for a short explanation of why someone jumping ...

Perhaps the answer is found in the following two references: In the companion volume "Firefly: Still Flying", there is a short story by series writer Jane Espenson called "What Holds Us Down" that describes the various aspects of the gravity rotor and the Honecutt Capacitors that are a part of the system for generating a relative gravity and inertia damping ...

I'm pretty sure this is "Noise Level" by Raymond F. Jones. http://www.sf-encyclopedia.com/entry/jones_raymond_f: "Noise Level" (December 1952 Astounding), an archetypal Astounding tale of Conceptual Breakthrough, scientific advance taking place through destruction of a previous paradigm: Scientists are told that Antigravity exists, and so proceed to ...

This is addressed in the TNG Technical Manual. The Enterprise has artificial gravity (of 1g) pulling the inhabitants downwards. When the ship experiences sudden unexpected movement, the ship is able to compensate to prevent the crew from fatally slamming into the walls, but there's sufficient lag in the system that still allows unpleasant lateral movement. ...

There are three modes used in various sci-fi works, and a 4th in some space-fantasy settings. Mode 1: Artificial Gravity. This is safely assumed anytime you see decks aligned parallel to the flight path... in other words Aft is back, not down. The details of how AG works vary widely by universe, but it's all handwavium, so for practical purposes, it's ...

Because if such ships did not have artificial gravity or inertial compensators, the occupant would be reduced to chunky salsa every time the ship sped up, slowed down, or rounded a curve. This website says Yavin is 198,000 kilometers across. So going around it from the rebel base on its moon will take several minutes. This video snippet says after the X-...

Speculation In the trivia notes for the Axiom Pixar Wiki it says: When WALL-E first sees the Axiom, it is located behind the Horsehead Nebula. A large Nebula which is starting to form star clusters would have gravity. It is possible the artifical gravity in the Axiom has adjusted itself to deal with the nearby nebula. So when the Pilot yanks the wheel ...

It is not gravitational We can be quite sure that the station is not spinning for the purpose of creating gravity, because the final scene of "What You Leave Behind" zooms out of an upper Promenade window into space, and clearly shows that the floor is oriented towards the "bottom" of the station rather than towards the outside. Spinning would not create ...

The Firefly / Serenity universe clearly includes some sort of control over the laws of acceleration and inertia. After all, the crew members don't fly against the back of the ship every time it flies off into the sunset. The Crazy Ivan in particular would have flung them to bits instead of just lightly pushing them around. Since there's no real difference ...

In TOS: The Doomsday Machine, we see a crippled, nearly destroyed USS Constellation. The gravity still works. In TNG: Booby Trap, we see a ship which has been in an energy draining environment for centuries. The gravity still works. In ENT: Broken Bow, we see Mayweather exploiting Enterprise's "sweet spot": a section of the ship where the overall gravity ...

As far as I remember, they never gave out that level of detail on the TV show. We're just told that Ceres has much lower gravity than Earth. In the novels that the show is based on, the gravity is artificially generated "spin" gravity, which does match the visual on the show: "down" is actually pointing out into space. Note, for example, that the airlocks (...

There are several possible approaches. Sidestep the problem. Some books find uses for Dyson spheres that don't require them to have internal gravity. Some examples of this include: If your Dyson sphere is actually a Matrioshka brain (as in Accelerando by Charles Stross), you don't need any gravity. Computation works fine in zero-G. The sufficiently ...

The Wiki speculates that stars are held in place magnetically. I don't believe it is ever specifically stated, but I believe that the stars are most likely held in place by the same technology that allows the Commander's Hooks to function. The Hooks allow the army commander to move freely throughout the Battle Room during practices, and also allows the ...

In order to hover (approximately) in place over the surface of the rotating habitat, the helicopter does need to exert a force "upwards", i.e. towards the axis of rotation. This is because the habitat is rotating, which means that its surface is constantly moving around the axis. But the surface is also constantly being pulled towards the axis by the ...

This sounds like the Giant Series by Paul Hogan. Specifically, the 2nd book in the series the Gentle Giants of Ganymede. In it, the Ganymeans (so called because their ship was first discovered on Ganymede) are a race that evolved in a world (Minerva) which did not have any predators. Hence, they never developed many of the aggressive traits of humans. ...

It varies from universe to universe. For instance, in Star Wars, this explanation is about all you get: Artificial gravity generators were used to create a stable field of gravity outside of a planet's natural gravity well, thus aiding life in space. (There's more, but that's the main point.) In Star Trek, I can give you a little more. In the Star ...

The Star Trek TNG Technical Manual (considered a canon source of info about the Star Trek Universe) contains a wealth of Treknobabble explanation regarding the presence of gravity aboard ship. In short, the technology is very similar to that of the Tractor beam; a small device buried below the deck plating emits gravitons which then attract anything ...

Artificial gravity doesn't just apply a constant force; if it did, it couldn't compensate for the tremendous accelerations starships routinely undergo. (Evidence: The crew is not turned into strawberry jam on the rear bulkhead every time they go to warp, or even low impulse.) Atmospheric reentry (more accurately in this case, atmospheric entry) can involve ...

No. The objects inside the spinning wheel will experience an artificial gravity effect which appears to be pushing outwards from the center of the wheel. Since all the objects inside the station (including your bristles) already have a considerable amount of motion relative to a stationary observer outside, they will simply travel to the outside wall (e.g. ...

For manned craft that travel at the speeds involved in Star Wars, artificial gravity is a necessity. Small changes in direction would produce forces that would pulverize a human pilot. So if you want to have fast-moving one-man fighters in a science fiction setting, they need to have artificial gravity to cancel out the accelerational effects. From the ...

Artifical gravity (or better to say the feeling of gravity) in ‘Interstellar’ is generated by means of rotation (see: Wikipedia). This force is depending both on the rate of spin (rounds per minute) and the diameter. While docking at the inner part of the ship the force would be very small and near zero g. In the outer parts of the ship (where the crew ...

It seems that the film's Director was well aware of the issue but apparently decided to ignore it for the sake of story-telling (and presumably also for budgetary reasons). In an interview for EMPIRE, he unequivocally shows that this was a consideration; Interviewer: And is it true that you had a screening for Buzz Aldrin? Duncan Jones: Well, I gave ...

Apparently they have artificial gravity in the Friday 'verse. From chapter 27: I dislike the Beanstalk [the space elevator] and I don’t care much for the twenty-four hour Station. Aside from its spectacular and always changing view of Earth it has nothing to offer but high prices and cramped quarters. Its artificial gravity surges uncomfortably and ...

It seems that if the TARDIS is in normal flight, it has fixed up/down orientation. However, if it is being acted on by some outside force (Angels, crash, impact with the Titanic), then the contents are affected by the movements of the TARDIS due to that force. While I can't recall the TARDIS ever being turned completely upside down, or even on its side, it ...

Not directly in TNG In Conundrum, we see: Dr. Beverly Crusher tending to Kristin, a crewmember injured cliff-diving on the holodeck that holodeck program was Holodeck Program 47-C. So, although we don't observe it in TNG, we assume that in TNG the holodek could manipulate gravity with this program, otherwise Kristin would've fallen straight to the ...

This is an excerpt from the excellent Inside the Worlds of Star Wars Trilogy: The Ultimate Guide to the Incredible Locations of Episodes IV, V, and VI factbook. As you can see, gravity on the Death Star is generated locally. On the outermost layers of the vessel, the orientation is toward the centre. Once you go more than a few layer inside, the gravity is ...

Every room in the TARDIS apparently has it's own gravitational controls. The clearest example of this is in The Doctor's Wife when House has taken over the TARDIS (presumably looking for Vicodin?) and Amy/Rory are running through the halls. At one point House turns off the anti-grav on a room that is apparently tilted sideways, and Amy/Rory almost fall down ...
