Inside an o'Neill cylinder, would a Pendulum's swing have any notable characteristics? [migrated]

Objects inside an O'Neill Cylinder would feel the Centrifugal effect, given by: $F=mω^2r$, and the Coriolis effect, given by: $F=d(mv)/dt$, as well as air friction from air under the same effects. At ...

Inside an o'Neill cylinder, would an enclosed room feel the same "gravity" as an open space?

I know that the "gravity" in an O'Neill Cylinder is from Centrifugal effect. Calculated by: F=mω^2r F is centrifugal Force m is the Mass ω is the Angular velocity r is the distance from ...

Adapting to normal gravity after spending time in centrifugal artificial gravity

So pretty much, my world contains a lot of space travel/colonisation, and people live on ships with artificial gravity via centrifugal force. The diameter of these big spinny cylinder things (?) is ...

How hard scifi is a graviton gravity drive?

What if, hypothetically, gravitons could be captured and stored. Then, a beam of gravitons is projected in front of the ship, each individual graviton not having much pull, but together, warping space ...

Would a ring generating a strong gravitational pull keep those inside unharmed?

My spaceship includes a technology that creates artificial gravity (AG). For all intents and purposes the inner workings of the device are unknown. It's essentially a black box. What is understood is ...

Gravity at the interior poles inside a large spinning sphere?

From other answers I've determined that gravity on the interior of a large spinning sphere (like a Dyson Sphere) could create a desired gravity at the equator at the inner surface. But what would ...

How can you create non-centripetal artificial gravity and apply it to propel a spacecraft by riding the gravitational space time warp?

I like the idea that it is possible to use the warping of spacetime as a propelling force to move spacecraft through an independent non-centripetal artificial gravity drive. This drive uses the ...

Black Hole for ship artificial gravity?

So in my universe ship use thrust or spin to create gravity. But what if I could “contain” (assume I can contain it) a black hole to use it for gravity. This way ships can drift and still have gravity....

How to redistribute weight on an O'Neill Cylinder? [duplicate]

Problem With a rotating cylinder, applying weight to one side and not the other will cause it to rotate off axis and give it a 'wobble' likely causing undesired gravitational effects. Now clearly ...

Is it believable to have a spaceship spin around a weight for artificial gravity?

In my narrative universe, there will be ships that use a 1g acceleration for artificial gravity. However, when they are not accelerating (whether on a longer journey at a constant velocity or simply "...
