So a lot of movies, TV shows, illustrations, etc., show spacecraft

The question I have for those more knowledgeable in this area than I

is: What is the connection between these two sections? Obviously

there shouldn't be a physical connection between the two hull sections

(right?). But would this mean space enough between the spinnning hull

and the stationary hull for the interior atmosphere to escape? Or is

it sealed somehow?



If you have separate rotating and non-rotating sections (as in, for

example, the movie "2010"), then yes, you need a rotating air-seal

between them. This takes a bit of effort for the engineers, but is

certainly possible.





Do you have any references describing how it could be achieved? I've

looked, and I cannot find anything.
