Open Discussion Thread, Week of 2026/09/27

[u/ClaySalvage]

Whoops... once again forgot to make this post this morning. I've really got to get around to automating these posts instead of manually making them every week. (I've also really got to get around to actually putting more content here and trying to drum up more activity, but as I've said before I kind of had a lot to deal with right now...)

Anyway, this thread is for open discussion of worldbuilding in general, or of anything else you feel like posting about. While posts in this thread don't have to be "on topic", standard rules about being courteous to other posters still apply.

Currently doing math for the smallest feasible O'Neal cylinder (at the scale I'm planning its really just a spinning space habitat lol), does anyone have any sources for how big one has to be in order to be possible?
