Saturn's rings have to be carded at the door. Their age has long been seriously questioned. Back when the claim that the Earth was billions of years old became popular, of course, the knee-jerk, quickly standardized view was that the rings of Saturn were about four billion years old. Of course. Then came the age of powerful observatories, space telescopes, and NASA's fly-by missions. Enter data. Today, it is increasingly difficult to maintain the more recent claims that the rings are 50 to 100 million years old.
An explosion appeared in the night sky in 1054 A.D. as a supernova remnant (SNR) and formed the Crab Nebula. Old-earth scientists have measured and calculated the expected rate that stars would explode. However, if the universe, and particularly the Milky Way Galaxy, is billions of years old, the vast majority of SNRs (like the Crab Nebula) that allegedly should exist, are missing.
