Harry,
The plasma papers link is spectacular !!
Thanks very much Harry, you are the king of the links !!
, it will keep me busy reading.
Anthony L Peratt sure is a busy fellow.
Printed out 5 papers in 64 pages !
Enceladus is, to me, adding to the rings as it loses mass by the ice fountains. It is so big it will take a long time to lose itself into making rings! If all the ring material is 'swept up' it wouldn't make a very big ball (would it?). So Enceladus is possibly the supply culpret in their creation, along with the earlier moon that was tidally pulverized.
Right ! as Enceladus' orbit decays, the tidal forces increase, and that is progenitor of the ice fountains. And so lately, last few 100,000 years, the outer rings have been forming from the ejected ice material. As the orbit decays more, look for fountain activity to increase.
Or would this be going the other way; like it is with our moon, Enceladous is moving further away from Saturn over time, as internal angular momentum losses by friction cause the orbit radius to increase ?
Or would that be Saturnian internal frictional losses cause Encaledus' orbit radius to increase ? Talk about action at a distance !
Sure would be interesting to see a time lapse film about 5 billion years of galactic evolution in an hour and a half ! And have it real footage !!
