I googled this question, and all I got was stuff about defeating the degeneration of the body in weightlessness, so I'm hoping I can get some insight
from people who know about geology.
What happens to a fluid in a centrifuge in zero g?
If you had a sphere or a cylinder that was half full of a fluid in a weightless environment, and you were to spin that fluid in the container, what
In a cylinder, would the fluid force itself to the sides of the container under centrifugal force, leaving a hollow center? What about in a sphere? In
a sphere, would there be air at the poles of it, as well as air in the center?
I'm wondering because I was reading one of those hollow earth threads, and I was thinking, if the fluid magma in the core of the earth was moving at
a sufficient rate, wouldn't it concentrate itself to the outside of the sphere, possibly leaving a hollow center, and possibly hollow poles, assuming
the earth was not completely full of magma?
