Saturn’s rings are new…relative to sharks. Sharks existed on Earth long before Saturn got its rings. Just learned this over a conversation and couldn’t help but wonder how many things we assume to be old but in reality, they are not that old.

“The findings indicate that Saturn’s rings formed between 10 million and 100 million years ago. From our planet’s perspective, that means Saturn’s rings may have formed during the age of dinosaurs.” - Source.
