Okay, gravity waves ring the rings of Saturn. Perhaps this process contributes to faster erosion and decay of the ring system too, thus making the ring system much younger than 4.5 billion years. The report wraps up with.

"Understanding what's going on deep in Saturn's heart is very much an ongoing process. According to Mankovich, ring seismology favors a thick stable region that makes up roughly a quarter of the planet's radius. That's somewhat at odds with understanding gleaned from the planet's magnetic field, which favors a narrow, stable region only 5 to 10% of the planet's interior. Mankovich says that it's too soon to say what the results imply about the planet's interior, but that one possibility is that the process that generates the planet's magnetic field is even more different from its fellow gas giant Jupiter than previously anticipated. "It will be a fascinating next few years as the full implications of the multi-instrument Cassini data are worked out," Mankovich said. But far from being dismayed by the clash, Mankovich appeared excited." "It's a testament to the power of a spacecraft mission like Cassini that we have such diverse data that different parts of it seem to say different things—it reflects a gap in our understanding and presents an opportunity for discovery. Scientific synergy at its best," he added."
