There is a another type of analysis not too much en vogue...that of
thinking about rings being in a location where there is the least
resistence and / or interaction. where a moon sweeps up a region of the
ring well there it goes..a nice hole between rings. All forces and
interactions in the viscinity of where saturn is and what saturn does
and all external forces say where and whe rings should exist no matter
what you arbitarily decide should be the rings origin, Waveyness in the
rings then would have the same general explanation plus the fact that
that rings may also impart their own forces. what i have seen in some
of the pictures coming back is a spiral effect in the rings of globs in
the rings perhaps having enhanced gravity probably due to black body
radiation retention...the same effect has been observed among the
asteroids in asteroid belt. The only explanation for enhanced gravity
of small masses is a new theory of thermodynamics being the actual
cause of gravity (as the effect) such that the sum of energy and the sum
of mass retained by a massive body minus the sum of lost energy and
lost mass over a set period of time will acount for any gravity anomoly
of enhancement. (turns out its not just the anomaly!)
