Scott Manley surveys the research on whether people can adapt to rotating artificial gravity, from early Soviet centrifuge tests to modern studies. He concludes it is an engineering problem and discusses Coriolis effects and station radius.
Why Hacker News points people here: Linked as the clear explainer on rotational gravity and its Coriolis oddities.
“Scott Manley has a great video on artificial gravity in space”HN comment, 2022
“it’s a good and informative watch”
Shows rotating artificial gravity is feasible at ISS scale, radius as small as 40m.
Scott Manley did a video looking at this, it’s a good and informative watch: this video The gist is that is actually doable at the same(ish) scale as the ISS. Bigger is better but we can do it at a radius as little at 40m.
“Scott Manley has a great video on artificial gravity in space”
Covers artificial gravity concepts including early Soviet centrifuge tests in space.
YouTuber Scott Manley has a great video on artificial gravity in space, including concepts that resemble the article's proposal: this video Before I watched the video, I didn't know the Soviet Union tested a (small) centrifuge for artificial gravity in space back in the 70s: link
“Coriolis effect and other issues that make rotational "gravity" feel really weird”
Discusses Coriolis effect and oddities of rotational gravity.
Does this address the Coriolis effect and other issues that make rotational "gravity" feel really weird compared to actual gravity (6:58 this video )?
“See 6 minutes in”
Explains Coriolis problems of rotation-based gravity.
Why not just use rotation to generate artificial gravity via centrifugal force? I guess the answer could be that the sideways motion will drive you crazy due to coriolis forces? See 6 minutes in this video But they can just substitute windows with monitors that compensate for the view. Incidentally, the viewscreens on Star Trek etc. always had the ship right side up, so they probably compensated exactly in this way :)
“Relevant Scott Manley video”
Relevant discussion of rotating gravity and its effects on movement.
Relevant Scott Manley video: this video Relevant tom Scott video: link There is a lot of research, but it’s not as simple as operating under real gravity. Makes many movements harder and can result in getting sick.
