You're also confused about 0g at the center. You'd have some small

The centre lab could rotate relative to the rotating station to give it
a neutral position relative to space.


So now you've got the same vibration problem that you get with a
treadmill. If you're going to play that game, there are easier ways.


The vibration isolation racks
developped by NASA would eliminate any vibration from the station
retating around the structure.


Yeah, sure. And if frogs had wings they wouldn't bump their asses
when they hopped.
