I've just watched the first episode of The Expanse. I notice in a couple interior shots set in, I presume (by political content) Ceres, the producers/director took care to include a small bird, which flew very oddly.
This bird would flip its wings, then fold them, then flip again -- much like certain songbirds do on Earth, except that on Earth they don't hover between flips; they fly a ballistic arc. This (along with mentions of "bone density juice" and the presence of "long-bones", extremely tall folk who'd grown up in low-gee) led me to conclude that the interior gravity in Ceres must be much less than 1 G, despite the (presumably production cost driven) lack of any apparent effect on human walking, no "floating" balls in a scene with playing children, and so forth.
What level of (presumed centrifugal) artifical gravity is maintained in Ceres?
