Shape is what our impoverished
sensibilities can manage and might be
inadequate to an understanding, and
possibly a nonconstructive diversion.

Logical deduction and plain ol' horse sense, 'intuitive extrapolation'
if you will, would look at it this way-- there is a seen a common
planform throughout nature at every level, common to all rotating
systems. That's two hemispheres and a common equator rotating on a polar
axis. Why would the unseen whole of the macro-universe NOT also be a
rotating system displaying the same planform as seen everywhere else in
nature?
