So Uncle Al drags his butt down to the local humongous university with its mammoth science library (and equally large parking fees) that now mostly consists of terminals and USB ports. He turns on, tunes in, and searches for "gravitation" "journals" in the card (byte?) catalog. What does He get? 5 journals 14 NASA microgravity periodicals NASA - Shiiiiit IIIIIIn Spaaaaace! -- Uncle Al http://www.mazepath.com/uncleal/ (Toxic URL!

And this: "Let's go deeper What researchers really need is a good look deep inside the sun. NASA's Solar Dynamics Observatory, launched in February 2010, will provide that when its instruments come online later this year. SDO is able to map the sun's interior using a technique called helioseismology. SOHO can do the same thing, but not well enough to trace the Great Conveyor Belt all the way around. SDO's advanced sensors might reveal the complete circuit, which "could be the missing piece we need to forecast the whole solar cycle," said Hathaway. The research was published in today's issue of Science." http://www.space.com/news/sun-record...or-100312.html The claim is that while the top has speed up, the bottom has slowed down. Sounds uncomfortable. --Mike Jr. |

Determining the interior of the Sun,like that of the Earth is a speculative endeavor hence such an assertive pseudo-authoritative 'surprise' does nothing,at least not today.Unlike others here,I was working with two large external rings surrounding a star with a smaller intersecting ring back in 1990 or 4 years before they were observationally discovered - http://chem.tufts.edu/science/astron...es/sn1987a.jpg While it is the only copyright I ever took out and really means nothing other than I was working on the stellar geometry in terms of natural efficiencies in 1990,it is now a private work ,something I take a pride in working on when nobody else was and perhaps never will even though it has been observed. All rotating celestial bodies with viscous compositions display latitudinal differential rotation or what amounts to the same thing - an uneven rotational gradient between the maximum equatorial speed down to polar latitudes as opposed to something like the Earth's fractured crust which has an even rotational gradient with a maximum equatorial speed of 1037.5 miles per hour.There is no reason to believe that the Earth's viscous interior is exempt from differential rotation,after all,it displays the expected spherical deviation of 40 km due to that uneven rotational gradient,stars of the same mass but with different maximum rotational speeds display variations in spherical deviation,the faster it spins the greater the spherical deviation due to more differential rotation shear bands on a faster spinning star . In short,in order to investigate the consequences of differential rotation,on a star or on the fractured surface crust of the Earth,speculative notions of 'convection cells' as described in that article have to be set aside, but with the global geographical feature of the Mid Atlantic ridge requiring a global mechanism,the only suitable candidate is the lag/advance mechanism inherent in differential rotational shear bands and its tendency to generate symmetrical crust either side of the Mid Atlantic ridge with special note of the 'S' shape,the fracture zones running parallel with the Earth rotational characteristics and other great clues linking planetary dynamics to evolutionary geology.

I have to laugh at the 'hotspot' explanation which has a mobile crust moving across a stationary interior thereby defying logic but there are any amount of these novelties floating around which are just too inane to respond to and I would hope people can do better than that.Better to look at Google Earth and the Mid Atlantic Ridge with its magnificent fracture zones following the Earth's rotational characteristics along with that sharp divide at the equator - http://www.huttoncommentaries.com/su...manche750..jpg 'Convection cells' require no specific reference to the Earth's rotational dynamics hence I do not give them any thought in geological processes whereas astronomical observations of rotating celestial compositions affirm a general rule that rotating objects with viscous compositions display differential rotation and there is every reason to believe that our planet is not exempt from this feature,the problem being that contemporaries organise the Earth's interior viscosity to suit 'convection cells' even though observations determine a more dynamic interior which I have no problem with - http://www.youtube.com/watch?v=jXDyU...eature=related I have no idea what data the GOCE satellite will present however they have already picked up differential rotation beneath the crust but have misinterpreted it and nothing like the way I recognize it as an astronomer and its geological clues on the surface crust.I am not going to throw good information after 'convection cells' a a mechanism for crustal motion yet it remains to be seen whether somebody can make the leap which links rotational dynamics with crustal evolution and the planet's spherical deviation using a common rotational mechanism. |

Recent high pressure and temperature investigations indicated that partial carbonate melt should exist at the bottom of the lithosphere and at 660 km. The presence of few percent carbonate melt reduces the viscosity by several order of magnitude. The globally existing 660 km very low viscosity layer allows the development of differential rotation between the upper and lower mantle. This differential rotation between the 660 km outer shell and the rest of the earth offers a plausible explanation for plate tectonics and for the generation of the earth’s magnetic field. Simple dynamo model is proposed, which able to reproduce all of the features of the contemporary and, within reasonable uncertainty, the paleomagnetic field. The model is also consistent with geological and geophysical observations." --Mike Jr. |
