Tonight on PBS was a Nova program about the magnetic field created
from the Earth's molten iron core producing a magnetic dynamo where the electric current created from the motion of the molten iron increases the magnetic field which in turn increases the electric current. I was rather surprized to hear that it took 50 years before acceptance of "reverse polarity". Surprized because let us consider the Earth a machine. And unless the machine is near perfect with few blemishes that the reverse polarity would be a commonplace occurrence because of the Earth's many flaws from that of perfection. That the sloshing around of molten iron in the Earth's core should be a crude happening and thus many chaos attractors involved in the molten iron to form. And since so many chaotic attractors that reverse polarity commonplace and so why the acceptance took 50 years. Some 50 years ago if a physicists were to get up in front of a crowd of geologists at an important convention and related the above that the iron core would be full of chaos-attractors that reverse-polarity should be commonplace. Excellent hour program this was for it left remaining many questions of profound interest. To name a few: (1) what is the relationship, mathematically, of the Earth axis of rotation and where the "magnetic northpole exists"? I suspect the axis of rotation is a direct relationship to the magnetic north and the main cause of chaos attractors. Example: I doubt the Earth ever experienced a long period of time where the axis was nearly 90 degrees opposite the magneticpole to be what maybe called magneticeast. So has anyone in physics or geology or math related the existence of the Earth axis to the whereabouts of magneticpole. Keep in mind the above stresses "a long period of time" (2) I wonder if there is biological evidence that when these reversepolarities took place whether any species extinction coincided? (3) And apparently reversepolarity probably had little to no affect upon primate evolution and especially humanlike evolution going back 10 million years. We cannot say that Homo habilis just for an example was extincted due to magnetic shield loss. (4) If our present day polarity has lasted for 780,000 years and the average lasting is only 200,000 years then why or what reason has this period been so long lived?? I believe I have an answer for that from my theory of CellWell1 and CellWell2. (5) Does anyone know if the moons of Jupiter, in particular Europa which is believed to have oceans of water, does anyone know if Europa has a molten iron core and whether it has a magnetic field of considerable size?? (6) The object in our SolarSystem that is the largest internal magneticfield is Jupiter. So does Jupiter have a huge molten iron core? And is there some means or method of finding out if Jupiter has experienced magneticreversal?? Jupiter as well as every other astro body would be imperfect enough for the molten iron to slosh around chaotically from time to time and especially given the precession of axis to further the chaos. So is there some means of tackling whether Jupiter has had magnetic reversal. I am glad for this opportunity to review my theory of CellWell1 and CellWell2. Those of you who have followed me in the 1990s recognize that in an AtomTotality theory that the Universe has layerings of ages like tree rings or like onion layers and that is why I coined the name CellWell1 and CellWell2 for our SolarSystem. Because in an AtomTotality our present newest layer of the Universe is the Plutonium AtomTotality which is about 5 billion years old accreted new onto the older AtomTotality of the Uranium AtomTotality which is about 15 to 20 billion years old and we can go backwards through all the other AtomTotalities. That is why Freedman gets an age of 8 billion years old and Sandage gets an age of 20 billion years old because they are measuring age in different layers of the Universe. But not only the age of stars and galaxies are of different AtomTotalities but our own SolarSystem has different ages. The most recent newcomers to our SolarSystem are the gas giants and their moons. They grow from the accretion of "cosmic rays" and Jupiter is the most vigorous grower because most cosmic rays end up inside of Jupiter. So the gasgiants comprise the most recent age in our SolarSystem and I call them CellWell2. The gas giants are about 5 billion years old coinciding with the "minibigbang" that was the PlutoniumAtomTotality onto the older UraniumAtomTotality. The Sun and Mercury, Venus, Earth Mars date back to the older UraniumAtomTotality and are anywhere from 15 billion years old to 20 billion years old. And they looked very much different than now. Earth some 15 billion years ago was like Europa to Jupiter is now. Earth was a satellite to a larger planet which got swallowed up by the Sun and the Sun was probably not a star until about 10 to 15 billion years ago. So, from watching this program and learning that Mars craters of Argyle and Hellas (excuse the spelling) were 4 billion years old with no magnetic inheritance suggests support of the CellWell1 and CellWell2 theory. What I need to find out is whether Europa or the other moons of Jupiter have a similar background history as what Mars seems to have. For it would indicate strongly that both Earth and Mars at one time in their ancient past, some 15 billion years ago were moons of some gas giant which we will call Zeus. This Zeus gas giant would eventually be swallowed by our protoSun but the moons saved or spared from collision. And before Mars reached its present day orbit, it had teeming life and oceans. Same goes for Mercury and Venus. Same goes for probably most of the moons of Jupiter and the other gas giants in that they also will have teeming life and oceans and then their gas giant planet become swallowed up to form a star. Many of the moons will also be swallowed up. And our SolarSystem will then have twin stars and not a solo Sun. Many of the exoplanets discovered in the late 1990s show evidence of huge planets circling close to their solo star. That is the common evolution of most every star in the Universe in that they start out solo and with time in each new AtomTotality layer gas giants are created and then swallowed together to form a twin star SolarSystem. Summary: the most important hunt from this TV program is to see whether Europa and the other moons of Jupiter have any sort of resemblance to Mars. Does Europa have a liquid iron core and if not how much more mass to give it a liquid ironcore. And what extent of a magnetic field??

I was rather surprized to hear that it took 50 years before acceptance
of "reverse polarity". The evidence that clinched it was the correspondence of the age of seafloor magnetic stripes to land rock measurements. Land rocks are subject to a large number of false magnetizations- lightning strikes, chemical weathering, mechanical burial stress, heating, tectonic reorientation- that it took decades to sort these out. When I measured rocks, we'd routinely account for a dozen common effects, with dozens of others reported in the literature. Its just that the preponderance of evidence- now thousands of seafloor magnetic tracks with over a million land rocks- started to agree by the late 1960s. I am not fully convinced that Nova's claim we are in a reversal now. Perhaps we are just in a period of "normal" variation, which can be between 20 and 100 microTeslas according to the pottery measurements (shown in the Nova show). I view the field as kind of a "flickering flame" that tests stability now and then, with a catstrophic reversal rarely. Nova showed Glatzimier's "lava lamp" numerical animations of domain fluctuations during the reversal period. However, the same movies between reversals also show fluctuations to a lesser degree. |

Theres a 33 million year constant period during the Cretaceous.
Perhaps a similar one during the Jurassic. As you go back in time the rock record is more sparse. Over billions of years there may have been times when the core may not have been segregated from the rocks, or mantle convention and plate tectonics not turned on yet. But the above times were practically "last week" on the Earths time scale. |

Thought Experiment: let us take a cup and pretend it is a scaled down Earth and let us take the liquid
content as the Earth's molten liquid core. In this scaled down model we need some liquid that imitates molten iron for it is too dangerous for our experiment. I need some liquid that has the viscosity of molten iron. I am sure some chemist can find a liquid with a viscosity to match molten iron in a cup. Let us say it is water. Now I need a spin on the cup to match the Earth's spin on its axis. Question for physics: it seems that spin of a planet is more secure and lasts much longer of its integrity than does the orbital revolution of a planet. Given the two, apparently the revolution degenerates much quicker than ever the spin. Can a physicist provide a simple reason for why that is true. That angular momentum or linear momentum degenerate so much faster than does spin. Anyway, getting back to the Thought Experiment. So we have a cup that is a scaled down model of planet Earth with its inside a liquid that mimics Earth's molten iron core and it has a spin to imitate the actual spin of Earth. So how much of a centrifuge effect happens to the liquid? And can there be enough chaos attractors to make the liquid circulate inside the cup to mimic a reverse polarity? I believe so. And it says that Convection currents are rather irrelevant. But it does need another condition. Condition: that the molten liquid iron core of Earth is not solely iron we are talking about. It must be a large abundance of some other metals or metal alloys such as nickel, copper, perhaps even mercury and lead. So, now, if our cup with liquid water is spun to mimic Earth, and now we remove the water and add something like 50% water and 50% orange seeds and then spin the cup. What happens is that there is a centrifuge effect and the seeds migrate from top to bottom and back to top and repeat in a cycle. So, I think the periodicity of the Earth magnetic pole reversal is caused by the Spin of the Earth on its axis and secondly, because the molten liquid iron core is not 100% iron but that the heavier metals such as nickel, copper, mercury and lead comprise perhaps 40% and iron the other 60%. And because of the differences of these metals that the flow migration of these metals from top to bottom and back again results in a magnetic field reversal. So the two things (1) Earth spin on axis (2) the core is two or more metals and not just iron alone, create a condition in the core that is a centrifuge-- mind you spherical centrifuge -- in which the up and down back to up motion of the heavier metals causes a magnetic field reversal. I believe the convection currents are not source of polarity reversal and convection currents are to chaotic and not able to explain the cycles. The centrifuge effect of various metals explains the cyclical character of polarity reversal.

Of course, the theory of a "molten iron core" is just that; A theory. I've seen little proof that there is actually molten iron sloshing around down there. And if there is, how exactly did the iron separate from the rock etc that usually spews out of volcanos? The only problem is that the existence of the earth's magnetic field rather limits speculation and alternative theories are scarce. Nova, I've noticed lately has become a spokesman for traditional scientific dogma. They make little effort to provide any alternatives to the party line. Let's at least be thankful that we didn't have to listen once again to how Newton "explained" gravity and how "all of electromagnetics" can be calculated from Maxwell's four simple equations. (As we did in the recent program on strings) Feh. I was rather surprized to hear that it took 50 years before acceptance of "reverse polarity". Surprized because let us consider the Earth a machine. And unless the machine is near perfect with few blemishes that the reverse polarity would be a commonplace occurrence because of the Earth's many flaws from that of perfection.

Some 50 years ago if a physicists were to get up in front of a crowd of geologists at an important convention and related the above that the iron core would be full of chaos-attractors that reverse-polarity should be commonplace. I don't know why you'd be surprised. The rejection of radical new ideas has been a hallmark of official science forever. I mean, even Ohm who proposed a totally simple relation and even provided the experiments to prove it was booted out of his university for doing so. Hell, Even Newton had to publish Principia privately. Really open minded...no? Shame upon science! But all that aside. I find even given a molten iron core, I doubt that there is a whole lot of "sloshing" going on! First off, planetary rotations tend to be reasonably stable and there would be a HUGE amount of inertia in such a core. But if you've ever played with self-exited dynamos, you'd know that it takes VERY few perturbations to cause things to change. These devices not only can start in either polarity, they tend get rather usnstable as output drops. So given external perturbations which could be simply gravitational effects of other bodies and the like as well as internal chaos-attractors, as you term it, in the core itself, it seems a very reasonable theory that if the system were to go into a cycle of lowering output (as we seem to bee presently) that there would be a strong possiblity of a total polarity reversal. So the bottom line here is that this theory is reasonable if unproved, but the fact that it was rejected for 50 years means that other interesting supporting data (such as the extinction of species) wasn't bothered to be looked for. Hence science dogma has placed science behind the curve once again. But, since we seem to have the possiblity of another reversal soon, we earthlings may soon have the opportunity to observe first hand the physical effects of such reversals. (And I STRONGLY suspect it will go WAY beyond a few cases of cancer and pretty lights in the skys over London as the program suggested. For starters we could add the total disruption of all communications... not such a minor thing in a modern society) bjacoby |

The idea of magnetic reversals gained acceptance through the accumulation of
evidence. It was previously rejected because the evidence was insufficient. This is exactly the way science is supposed to work. Extinctions can be caused by other factors, and, AFAIK, most if not all major extinctions are still explained by other causes. I only saw the end of the Nova show, so I can't comment on the information presented there, but I doubt that any serious geophysicist thinks the iron core is "sloshing around." Differentiation of the Earth's components occurred early in the Earth's history, and this has been generally accepted for a long time. The core is thousands of miles below the crust, which is where volcanoes occur. This stuff separated due to gravity when the Earth was mostly in a molten state. The crust is mostly composed of lighter rocks, and the mantle and core of heavier rocks. The existence of an iron core is the best explanation of the Earth's magnetic field, its mass, and seismic data. -- Curtis Croulet Temecula, California |
