Its only impossible if you assume gravity is the primary force holding the planets in their orbits.
according to Einstein's retarded theories
Circling 300 times farther from the star than Earth orbits the sun, the object could be a planet, perhaps one that was catapulted out into the nether regions after a collision or close encounter with an as-yet undetected sibling planet.
Another option is that the object, designated as 1RXS J160929.1-210524 b and located about 500 light-years away in the constellation Scorpius, is a new type of failed star -- something akin to a brown dwarf, though about half the size -- which formed along with the primary star about 5 million years ago.
models of dust in space say that can't happen.
Although researchers haven't figured out for sure what might cause such turbulence
We present several independent in-situ measurements, which provide evidence that charged dust in the E-ring interacts collectively with the dense surrounding plasma disk of Saturn, i.e., form a system of dust-plasma interaction.

From the Nat Geo article:
Although researchers haven't figured out for sure what might cause such turbulence
Because there is no turbulence.
When scientists try to model dust in space, they find that dust WILL NOT ACCUMULATE INTO PLANETS because turbulence prevents the dust from aggregating. Kilometer sized building blocks or larger are necessary for such “accumulation” models to work based on gravity alone.

Didn't someone say this just recently?

Now who was that? Oh, it was you. Which is it? Turbulence, or none?
[edit on 7/7/2010 by Phage]
Gas-rich planets such as Jupiter and Saturn grew from a disk of dust and gas which eventually crumpled like a piece of paper under its own gravitational instability -- or so one theory goes.
Now a computer simulation suggests that this idea falls apart under the turbulent forces within early protoplanetary systems.
The old, favored theory relies on the protoplanetary dust disk becoming denser and thinner until it reaches a tipping point, where it becomes gravitationally unstable and collapses into kilometer-sized building blocks that form the basis for gas giants. But 3D modeling has shown for the first time that turbulence prevents the dust from settling into the dense disk necessary for gravitational instability to work

OK fair enough, these are not your models. Granted, I'm an anthropologist not a physicist so I'm not an expert in this field but I think I have a firm enough grasp on the scientific method along with a good dose of critical thinking and the ability to read and I am just not buying it. We'll have to agree to disagree and call it a day. Some of the papers sited in the abstract you linked were written by legitimate physicists and cosmologists so the science behind it may not be completely bull#. However, my uncle taught Eric Lerner at Columbia so I can say with some certainty that he is considered to be on the fringe of "real" science and most of his work is quickly discounted. Does that discount the legitimacy of the science? No. Personally I'd be thrilled for conventional theories to be wrong. If that were the case then faster than light travel becomes more likely. I would just need a LOT more convincing at the end of the day. I'm not arrogant enough to say none of this is possible, i just see it as highly improbable at this stage of the game.

The tidal effects of Saturn prevent the coalescence of the material in the rings. It could be those very effects which destroyed a former moon and created the rings in the first place.
Turbulent, two-dimensional, hydrodynamic flows are characterized by the emergence of coherent, long-lived vortices without a need to invoke special initial conditions. Vortices have the ability to sequester particles, with typical radii from about 1 mm to 10 cm, that are slightly decoupled from the gas.

And how does the "ejection model" account for angular momentum in both the orbit and rotation of the planet?

I have some more anthropology questions.
Like why dinosaur were flash fossilized all over the earth around the same periods.
I'm curious to know why fossils are not created all over at the same rate today.
I'm also curious to know why fossil sea records are limited to dry land (again, plasma cosmology to the rescue)
I'm also curious to know why sea floor core samples show the age of the floors to be youngest at the mid ocean rifts.

invisible monsters?
You must be talking about black holes, dark matter, dark energy, strange matter, WIMPS, MACHOS, and god knows what other nonsense the general theory requires these days.
