How did Saturn come by its rings?

Saturn’s rings may have originated from a satellite that was stripped of its surface ice when it moved perilously close to the planet.

Interesting...

I thought I had read about a "cosmic collision" theory too, as well as theory of accretion of material potentially dating back to the formation of Saturn and the solar system.

The "tidal" theory would be unlikely to explain the apparent ring-like material extending far beyond the planet and the recently discovered Phoebe ring.

There is a new theory that they were created when one of Saturn's previous moons went into a "death spiral" that ripped all the ice off the moon. At that time, there was a ring of hydrogen around Saturn that trapped the moon in Saturn's gravity.
There ain'ta no sanity clause, and there ain'ta no centrifugal force ćther.
