If the rings of Saturn are the remnants of two or more large objects that 
collided, why are they so two-dimensional that they can hardly be seen 
edgewise? Why don't we have a Saturn "donut"?
If the solar system was created from a "shapeless" gas cloud, why did it 
suddenly assume such an extremely flat disc shape? The ecliptic (for the 
inner planets)is still very flat.
