Saturn's Rings

Cuzzi, Sky & Telescope 69, Jan. 1985, p. 22: "the expected bombardment rate would pulverize the entire system in only 10,000 years! ... f only a tiny fraction is truly lost ..., it becomes a real trick to maintain the rings....") Does anybody have good references to the actual dynamics of Saturn's rings? -- Mark Isaak eciton (at) earthlink (dot) net "Voice or no voice, the people can always be brought to the bidding of the leaders. That is easy. All you have to do is tell them they are being attacked, and denounce the pacifists for lack of patriotism and exposing the country to danger." -- Hermann Goering Mark, I've read that the rings are a transient (albeit long-lived) phenomena, but don't recall the details. The 10,000 year figure seems too low, but I don't have a good reference for that. I've added sci.astro.amateur because I suspect there are wise folk there that can give you a better answer.
