Why can't spaceships just accelerate to create gravity?

The answer to What happens to an astronaut who's floating in a spaceship (in space) when it begins to move? is that we can create g-force just by accelerating. So then why go all the way to create rotating ring? The ring makes sense for ISS, but why…

Would a ball bounced in a centrifuge return to the floor?

In other words, does the centrifugal force inside a centrifuge only work to simulate gravity when an object is "attached" to the reference frame inside the centrifuge? 1G at sea level is normally about 9.8 m/s^2, correct? However Centrifugal Force…

How would a drone work in centrifugal force generated "gravity"?

How would a hovering aircraft such as a drone operate on a rotating spacecraft that creates artificial gravity using centrifugal force? For simplicity, assume it's a drone on a space colony, similar to the render from Blue Origin below. Shown on the…

How much acceleration does it take for water to flow downhill?

Assume a hab in outer space with 1 atmosphere pressure and 23ºC (comfortable room temperature), To simulate gravity, the hab is spun. Acceleration is $\omega^2r$ where $\omega$ is angular velocity in radians/time and r is radius of hab. Obviously…

Can birds fly inside an O'Neill cylinder?

We know that birds can fly in a weightless environment from experiments with pigeons on the Vomit Comet. But on a very large O'Neill cylinder space station, could they fly the same way they do on Earth? Most birds fly by flapping their wings to…

Is it possible to create artificial gravity in a habitat in space, or on another planet or moon without spinning the hull of the habitat

I've seen many designs for creating artificial gravity within a habitat in space by rotating the habitat about a central axis. With today's science, can artificial gravity be generated in a vehicle, or habitat, that would mimic the gravity of earth…

Is there a name for this type of 'Spin Gravity' ship configuration?

I'm familiar with various proposed configurations for generating spin gravity from the Von Braun wheel, O'Neil cylinder, Bernal Sphere, the hamster wheel centrifuge of 2001's Discovery ship, the various large 'whole ship' spinning drums …

Are rotating habitats considered the standard solution for long-term human habitations in low-g environments?

It's long been proposed to build rotating colonies (ring worlds) in outer space. That concept can also be applied to surface colonies in low-g environments. (Luna is at 1/6th of Earth gravity; Mars is at 1/3.) Conceivably, spacecraft built for long…

Disadvantages of a short radius centrifuge for gravity simulation in space

For a free-floating space colony, what problems would the residents encounter if the radius of the centrifuge would be significantly less? I recently saw a video on this. It said that after a 10 day training course, people could adapt to low-radius…

static energy artificial gravity

We did this expariment at home. It was a lot of fun. But it got me thinking. The water in this picture is atracted to the balloon because of static. so couldent a simular principle be used to creat artificial gravity with a large static generator on…

electromagnetics as a form of Gravity

Wondering if anyone has ideas about creating an electromagnetic field in the Floor of an exercise room combined with clothing that is laced with metal strands. the intensity could be adjusted to individual needs. Thoughts??

Linear acceleration used for artificial gravity.

If we could actually get to the point where technology allows us to accelerate to 1 g for more than a few minutes, would that acceleration still need to be constant? Since a spaceship can't slow down in space because of the laws of motion, always…

Gravity on a spaceship

What if you lined the lower hull of a spaceship with osmium metal plating, would enough osmium plating create enough pull to simulate earths gravity?
