Doxxing, trolling, sealioning, racism, toxicity and dog-whistling are not welcomed in AskLemmy. Remember what your mother said: if you can't say something nice, don't say anything at all. In addition, the site-wide Lemmy.world terms of service also apply here. Please familiarize yourself with them
2) All posts must end with a '?'
This is sort of like Jeopardy. Please phrase all post titles in the form of a proper question ending with ?
3) No spam
Please do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.
4) NSFW is okay, within reason
Just remember to tag posts with either a content warning or a [NSFW] tag. Overtly sexual posts are not allowed, please direct them to either !asklemmyafterdark@lemmy.world or !asklemmynsfw@lemmynsfw.com.
NSFW comments should be restricted to posts tagged [NSFW].
5) This is not a support community.
It is not a place for 'how do I?', type questions.
If you have any questions regarding the site itself or would like to report a community, please direct them to Lemmy.world Support or email info@lemmy.world. For other questions check our partnered communities list, or use the search function.
6) No US Politics.

ok so i did some calculations:
If your ship is 9 m in diameter (just chosen at random, not because Starship is by chance 9 m in diameter)
that means x = r*cos(omega*t) and x'' = r*omega^2*-cos(omega*t) = 1g for t = 0 implies r*omega^2 = 10 m/s², r ≈ 4.5 m, omega ≈ 1.5 rad/s
so the ship would have to rotate with roughly 0.24 rotations per second or 14 rpm. seems doable to me. the outer walls would move with 6.7 m/s or 24 km/h.
Doable, not practical. Another major concern is the induced dizziness and general discomfort from such a small circumference. If you stand up straight, your head moves significantly slower than your feet. There are more effects that humans don't do well with.
In addition keep in mind that this implies significant mechanical complexity the moment you don't rotate the whole craft, but only a section or ring. If you do rotate all of it, simple tasks like taking a photo become... cumbersome.
Also like others have said, it's not a permanent residence for anyone, and the main goal of the ISS is the study of low- or micro-gravity.
Have you ever been in one of these?
You can easily sit on the wall while it's spinning, and it actually feels pretty normal. But, if you try and stand up and walk around...you're going to have a very bad day.
For some reason your link didn't work for me - in case it helps anyone else, here's the link again:

Thank you.
actually i have been, and i have attributed it to the device not providing consistent centrifugal forces. instead, gravity interferes and makes it inconsistent. which would not happen on a spaceship.
LOL of course it is doable to create rotation. But is it no good if living there is still unbearable.
I recommend you do some sea traveling, just a few months on a cargo ship on several oceans.
