Greenland sharks have existed for hundreds of millions of years through their ancient lineage while Saturn’s iconic rings are believed to have formed far more recently, possibly only 10 to 100 million years ago.
That means sharks were already swimming in Earth’s oceans long before Saturn wore its most famous feature.
I commented this when the last poster made this claim a month back: Sharks are older than most of the current, eaily-visible rings of Saturn. The E-ring is primary composed of material ejected from Enceladus, and there is no indication I have found which would suggest that the hydrothermal processes which cause the jets are anything new. Additionally, just because most of Saturn’s current rings were formed more-recently doesn’t mean there weren’t rings back then. The gas giants have hundreds of moons, and they certainly used to have more. I think it is an undeniable, generally - accepted fact that the gas giants have all had significant rings at some point in the past (and they all, in fact, do have rings, just not all as spectacular as Saturn’s current ones.
…which makes me wonder what the odds are of earth getting a ring once Kessler kicks off. But I suppose most of that junk is just going to burn up in the atmosphere and/or crash on somebody’s house.
