Of course. Isotopic abundances should be all over the map, so any force fitting of data should automatically cause concern. The fact that they have Earth's and Saturn's abundances matched doesn't say anything of importance by itself, because of peer pressure to conform to standards, and the standard is that the nebular hypothesis is correct, or else you get blacklisted/career opportunities vanish.D_Archer wrote:The water in Saturn's rings and satellites is like that on Earth except for moon Phoebe, which is out of this world:

A lot of misunderstanding because they just have to follow the already disproven nebular hypothesis, the data just does not jive with their preconceived notions.
I looked into the 'deuterium puzzle' a whole can of worms...
But this "result" is no issue for stellar metamorphosis, deuterium levels could go down over time or not.. Earth may have orbited or was close to Saturn at one point and feeded the rings, anything is possible. What is not possible is that everything as we see it is the leftovers of 1 nebular formation process because nothing adds up or makes sense that way. Also deuterium is not just formed after the big because there never was a big bang, so they need to collect more data about where the deuterium is and where it can hide and where exactly it is possible to form naturally not from a magic starting point. My bet would be HH objects/galaxy births or maybe even larger birthing events....
The paper above outlines a simple reasoning that we should be able to determine how old an object is by the ratio of O-16 to O-17/O-18. Light, against the heavy.
More light 16 = young
More heavy 17/18 = Old
The trick is that to use this method, which is still in its infancy, the isotopes used have to all be stable. No decaying isotopes allowed.
Phoebe is 5 times higher in the carbon isotope, this could mean a couple things. Mostly it means we have an extremely old object. So besides Earth's material matching Saturn's rings (allegedly), the only information I see in the article is that Phoebe is an old fart, vastly older than the object it orbits, Saturn.
It 100% is a piece of shrapnel from an impact event far exceeding the age of any large solar system body.
It is a piece of the remains of a dead, smashed up star that was older than Mercury. I'd place the object as far exceeding Mercury in age, easily over 65 billion years old.
