(i) I've already cited my source for the core's anisotropy in post #93.
I agree that the core is anisotropic, but I am asking about your specific reference to NS seismic waves traversing the Earth 5s faster than WE seismic waves. I couldn't find any reference to NS waves being faster than WE waves in the article you cited, nor the
original source for that article, nor the actual
scientific paper.
The earlier 2002 article that you cite in your latest post does say that NS waves are faster than WE waves, but it doesn't specify any value. (Where is the 5 second value coming from?)

I agree with this paper as well.
It seems to me that geologists have a pretty good handle on what the inner core is shaped like, what it is made of, and how dense it is.
And you think they are correct that there is an inner core, but wrong about everything else?
In fact, the more recent work by X. Song and X. Sun about the ``inner inner core'' suggests more anisotropy between the eastern and western halves (``eastern'' defined as between 40
o and 120
o east
longitude) than between the planar and axial directions.

This is a perfect example of why I am perpetually confused about your arguments.
Did you actually read this article? All 5 pages of it?
You are citing an amateur article which argues that gravity is actually a by-product of electromagnetism. Ignoring for a moment that this claim is demonstrably
wrong, how does this article help your theory?
This article
completely agrees that the gravitational inverse square law is correct! It uses the very same analysis (in particular, the
divergence theorem) which I have used before in my arguments with you!
The article argues (very poorly, and with many technical mistakes) that the
origin of gravity is actually an electromagnetic effect.
Unless you have completely changed your model of gravity (are you throwing your ``Archimedes screw gravitons'' out the window?) how does this article offer any support to your theory?
Or are you just using this completely amateur article to cherry pick the datum of ``Earths inner core revolves faster than the rest of the planet by 1/(1800 years)'' and completely ignoring the rest of it (i.e. where it describes an inner core that is basically the same as described by mainstream science)?
If you want to use the faster rotation of the inner core, why don't you cite an actual scientific article like
this one or an article in a more
reputable publication than whatever the article you found counts as?

Sure, why not?
The scientists in the article I cited above found that the inner core rotates faster than the Earth by about 0.27
o to 0.53
o per year. This suggests that the inner core completes one full rotation more than the rest of the Earth at some point between 679.2 and 1333.3 years.
In the study you cited, the scientists found a periodicity in climate of 1470 +/ 500 years (i.e. somewhere between 970 and 1970 years) which fits within the inner core rotation.
Finally, the analysis of the core by X. Song and X. Sun (cited above) predicts a W-E asymmetry in the ``inner inner core''; the eastern part (currently between longitude 40
o and 120
o east) has less crystalline alignment than the western part.
From this, one could
tentatively hypothesize that the orientation of the inner core with respect to the continents has some impact on climate cycles. For example, right now the less-aligned eastern part of the core is mostly under the Indian ocean or Asia.
Perhaps when this part of the core is under the Pacific ocean we will see a different climate pattern emerge.
This is a very
tentative hypothesis because I do not know any
mechanism which would connect the orientation of the inner core with respect to the position of the continents to the world-wide climate.
This hypothesis also has
nothing to do with your particular model for gravity or whether or not there is any exotic material within the Earth.
If you want to claim that the inner structure of the Earth has an effect on the climate, or even spacecraft flybys, I would not have any argument.
If you want to claim that the inner structure of the Earth is made of some sort of as yet unobserved exotic matter which has the unique properties of looking
exactly like high pressure iron whenever scientists attempt to study the core, but also has the unique property of subtly modifying the Earth's gravity field, whenever scientists
aren't looking, when certain spacecraft are attempting flybys or certain airplanes are flying over the ocean, well then I do have some pretty big arguments.
