Saturn's Rings Are Disappearing At a 'Worst-Case Scenario' Rate, NASA Says (usatoday.com)
A new study published in the journal Icarus found that Saturn is losing its signature rings at a "worst-case scenario" rate, and the bands could disappear completely within 100 million years. USA Today reports: The rings are being pulled into the planet "by gravity as a dusty rain of ice particles under the influence of Saturn's magnetic field," NASA said. The phenomenon is called "ring rain," and it drains enough water from rings to fill an Olympic-sized swimming pool every 30 minutes, said James O'Donoghue of NASA's Goddard Space Flight Center in Greenbelt, Maryland. "From this alone, the entire ring system will be gone in 300 million years," O'Donoghue said in a statement. "But add to this the Cassini-spacecraft measured ring-material detected falling into Saturn's equator, and the rings have less than 100 million years to live. We are lucky to be around to see Saturn's ring system, which appears to be in the middle of its lifetime."
Global warming?
accretion disks DO NOT condense into discrete well-defined orbital bodies like planets (or in this case, moons)
Planetary rings are not accretion disks. So your statement is already wrong from the first two words. Even so, there is evidence that some of Saturn's moons were formed partially out of condensed ring material.
the Big Bang theory as a simple explanation of everything we see.
The Big Bang theory has little to do with ring mechanics. Maxwell already had a comprehensive model of how the rings worked (based on Newtonian physics) 70 years before Lemaitre posed the idea of a Big Bang.
