Default Paper on Dynamics of an Earth Ring

Here is a short paper in which I make an argument that any ring system
around the Earth could not remain dynamically stable for long in the
complex Earth-Moon-Sun interactive environment:-

However.... some experts appear to suggest that such an "Earth ring"
could perhaps have existed for thousands of years, causing climatic
effects on the Earth, as revealed he

I wonder if anyone here has any views on this, or if there's some
other factor that I ought to have taken into account in my analysis?

*follow-ups trimmed - this has nothing to do with shuttle or station.
sci.space.policy has an (un?)official 'catch-all' role*

(uninformed speculation follows)

Well maybe they count debris within +/- 15 degress of the equator as 'a ring'.
Alternatively their article does rather gloss over the ring stability in favour
of the climatic impact - maybe their expertise just isn't as hot in that area.

I didn't realise these groups were moderated?!

Not immediately, you're right. However, if the station were to be
disassembled or expanded in the future by boosting it to a higher
orbit, then the dynamic instability of containment of any resulting
orbital debris in a perfect ring formation could become highly
relevant for all orbital spaceflight.

The scatter of debris over a 30-degree range would make the formation
so sparsely spread out as to make a significant blot out of sunlight
to impact Earth climate, impossible - IMHO.
