Questions tagged [artificial-gravity]

For questions about the use of technology to produce an alternative attractive force instead of gravity. Examples of alternatives might include magnetism or centripetal ("centrifugal") force. This tag is often associated with, though not dependent on, the "science-based" tag.

Using Diamagnetic repulsion to help negate the affects of weightlessness

I had an idea of a chamber that an astronaut would use when they would sleep that would allow their body to experience a gravity-like force to negate the negative effects of weightlessness, (Bone or ...

Could gravitational wave interference patterns be used for long range sensors detecting advanced spaceships?

Low energy, fantastic range From HDE in another topic, I learned gravitational waves have an intensity which is inverse proportional to distance, not square distance, like in electromagnetic fields.. $...

How does a spacecraft function despite it's own (non-centrifugal) artificial gravity?

Haven't done shipbuilding in a while so let me start simple. Sci-fi spacecrafts all tend to have some unexplained method of generating artificial gravity, which keeps the crew nice and cozy. The more ...

Artifical Onboard Gravity in a black hole's orbit

So this is a fictional question since I am dumb to science yet trying to write up a science fiction playing in the far future...but still would need the understanding of some deeper physics to be able ...

Would A Gravity Blade Be Possible To Create?

I am wanting to use gravity based weaponry in my plot. One of my ideas was to have some sort of blade that could focus extreme gravitational forces at the edge of the blade to slice through matter (...

How fast would the Moon (Luna) need to rotate so that anyone living in Lunar underground habitats would experience Earth-like gravity?

So I'm creating a sci-fi book, and I'd like to know a way to calculate how fast would the moon need to spin to create a certain amount of gravity, and how much energy would be required to get it to ...

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 ...

I want to design a realistic Anti-gravity tank, how do I go about this?

In one of my stories, some guys form the 22nd century introduce a gravity or magnetic based hover tank. The problem is I am limited to real world Armour technology and KE and CE type weapons. the KE ...

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 ...

Would an anti-gravity organ allow kaiju to avoid cube-square problems?

It is (around here, anyway) quite well known that science does not allow the existence of kaiju, mainly because of the cube-square law. bones rip themselves out To my understanding, this boils down ...
