Moon's bulge linked to early orbit (Aug 3)
http://physicsweb.org/article/news/10/8/3
Planetary scientists have proposed a solution to the centuries-old
problem of why the Moon's far side bulges at its equator. Ian
Garrick-Bethell and colleagues at the Massachusetts Institute of
Technology say that the bulge was caused by the Moon being much closer
to the Earth early on its history and moving in a much more eccentric
elliptical orbit than it does now. This would have allowed the bulge to
"freeze in" as the still-molten Moon began to solidify, the researchers
say (Science 313 652).

The real mystery is how, back then, they "observed" the bulge on the
far side!

The moon is shy
as in "shy on harvest moon"

But if "it was only a paper moon" they'd be able see its, uh, back side
during the crescent phases.

The German judge has tried and found you guilty of really bad puns, and
orders your execution at sunrise.

Thank you for the night. I hope it's clear.

They put up a really big mirror.

Sam,
The "man in the moon" with a bulge--who would have guessed? :-))

The rotational dynamics of the molten/flexible interior of the Earth
generates a deviation from a perfect sphere the fractured surface
crust not only profiles that deviation,the motion of the crust and
subsequently short term events such as Earthquakes are a consequewnce
of the same rotational dynamics,specifically differential rotation
perpendicular to the rotational axis.
The Earth's deviation from a perfect sphere represents a continuing
dynamic that would normally set investigators scrambling to consider it
in 21st century terms,if not just the deviation but the mechanism for
crustal motion but these are not normal times.
Instead,the misnomer known as the 'Equatorial Bulge' is a vague
artifiact of the Earth's formation based on rotation from the dead
center of the Earth with a stationary Earth convection cell mechanism
for crustal motion.That is just about right for the same crowd that
comes up with exotic nonsense about cosmological structure.
Try differential rotation of the Sun's plasma as a rough clue to
rotational dynamic occuring beneath your feet -

Thanks for the heads up. Looks interesting. The Science online article
is fee. Is there a no-fee preprint online for the article? - Canopus56
