Reversed Polarity Event-Earth's GeoMagnetic Field

Reversal of Earth's Geomagnetic Polarity and the Piezoelectric Effect

Many “end of the world” scenarios have been postulated over time. A recently popular one is that of the planet's poles shifting or reversing themselves, with predictably catastrophic results. But this theory is not just the stuff of grade B horror flicks—it has happened.

Periodically the Earth's geomagnetic polarity has been found to reverse itself, at irregular intervals, something on the order of every million years or so.

Cobb Mountain, in northern California, where I live, was the site of one such event. Labeled the Cobb Mountain Reverse Polarity event, this occurred a little more than a million years ago.

The nature of this phenomenon is poorly understood. Measurements have shown that the the strength of Earth's geomagnetic field gradually weakens prior to such events, although more sudden reversals have also been postulated. To use the most simple analogy, it appears the Earth's “battery” periodically runs down—the ultimate energy crisis! What to do? We certainly don't want a dead battery of a planet. It would pose an enormous waste disposal problem, for one thing.

Fortunately, creation accommodates itself by the phenomenon known as the piezoelectric effect, which is the ability of certain materials, normally considered to be nonconducting, to produce a voltage when subjected to mechanical stress. Typical examples of materials which exhibit this property include quartz crystals and ceramics (clay hardened by intense heat) – in other words, common materials which comprise much of Earth.

Tectonic plate activity seems to be responsible for the existence of the Earth's geomagnetic field (GMF). Therefore, it seems reasonable to assume that tectonic plate activity must necessarily periodically reverse its direction in order for the geomagnetic field to be restored to a state of relative, although reversed, normality. Of course, this is a summation effect— the result of the combined seismic activity of the entire planet at any given point in time. It should be a relatively simple matter to simulate this thesis as a computer program, which would provide some mechanistic support for the proposition.

How does this thinking differ from previous conceptions of the GMF? It is generally believed that the Earth has a “stable” GMF. I believe this concept is faulty. Not only do I believe it to be false, but also that it is impossible.

The GMF is a result of the inherent instability of the Earth's crust, primarily the structure of the lithosphere, which comprises the outer 100 miles or so of the Earth's crust. This in turn is influenced by deeper subterranean events which remain largely unexamined. Without instability, i.e. seismic activity, there would be no piezoelectric force generated. The “battery” would be dead indeed.

Albert Einstein, apparently as far back as 1905, puzzled over the nature of the GMF. The geodynamic theory was developed, which attempted to explain the existence of the GMF based on principles of heat exchange and fluid shifts. Einstein himself held the answer in his hands, yet he couldn't see it. He was even awarded the Nobel Prize for it! But it remained in his “blind spot”; his assumed knowledge blocked the acquisition of new knowledge. He was literally “looking in the light” (in energetic terms) for something when instead he needed to be looking in the “dark” (the world of form, of matter) to find it. It would seem that the relative movement of matter generates energy, the piezoelectric effect, and gives rise to the GMF.

Further, it has been predicted that the next polarity reversal will occur somewhere around
3000-4000 C.E. Based on geophysical data. Humanity's activities, particularly the use of fossil fuels and the destructive changes in our environment, appears to have accelerated this process. Can biological life as it currently exists survive this event? Is global warming the first event leading up to the reversal of geomagnetic polarity, which will come with a massive amount of solar radiation, in addition to the thermal up-regulation of the planetary thermostat? I think it is pretty clear that this is going to occur, and it will be sooner rather than later. I predict that, with the remarkable improvement in the health of many people in current generations, that some people living today will survive to see this cataclysmic event take place, along with the generations yet to come.

The photon explosion from our own life-sustaining sun alone will likely destroy all life forms in the absence of the protection of the GMF which currently shields us, unless the reversal occurs very quickly, minimizing our exposure to this intense solar energy. Such rapid polarity reversals have also been postulated to occur.

However, I suggest that the disappearance of formerly hearty lifeforms (such as dinosaurs) from our planet is evidence to the contrary. It seems that only the most robust strands of DNA would be capable of withstanding such radiation exposure, albeit with resulting mutations. These mutations may serve, however, to further enhance the resilience of resulting life forms.

While earthquakes are rightly feared for the devastation they can cause, and even more so in areas where they are relatively common, such as the Pacific Rim of Fire, they may be a very necessary component of the Earth's balance and its maintenance of the current polarity.

It follows, then, that seismic activity is an essential component of Earth's life-sustaining function in its attempt to be a perpetually hospitable place for all life-forms. Seismic activity, from subtle shifts in the tectonic plates to higher magnitude activity, including volcanic eruptions, are integral for maintaining the GMF—our vitally important radiation shield.

Knowing this, perhaps we humans can solve two pressing global problems with one solution. By harnessing geothermal deposits as a source of relatively clean energy production, we may be able to encourage low grade seismic activity and conceivably avert larger, potentially disruptive events. Wisely chosen sites for geothermal energy facilities, where drilling several miles into the Earth's lithosphere will unleash some of the potential energy stored in the Earth's crust, may serve to delay, perhaps indefinitely, the predicted reversal of geomagnetic polarity which threatens the entire biosphere.

I suggest the current economic and intellectual energy being put into exploration of outer space be redirected inward. The very same resources humanity has used to explore space could be adapted for further deep exploration of the Earth's mantle, and possibly even into Earth's core, to obtain the necessary data which will help us optimize our nascent geothermal explorations, driven by computer programs.

Based on the geological evidence of prior pole reversals and the evident negative effects on the inhabitants of Earth, one day, perhaps sooner than we think, our survival and life as we know it may depend on it.

Recent archaeological findings indicate that early hominids, approximately one million years ago, perceived the last polarity reversal on an experiential basis, even before the development of language itself. They have left us with a petroglyphic record of this; stone carvings which are especially abundant around the Pacific Rim of Fire. I believe the wisest ones among them carved out these rocks as a warning to the others, to take protection from the Sun. The most primitive petroglyphs consist of arrows pointing to the sun, seemingly emphasizing the need to take care and seek shelter, perhaps with directions to nearby caves and other shaded, protected areas.

Perhaps I need to clarify my concept of what petroglyphs are. I am utterly appalled and astounded at the term “rock art,” since a petroglyph, in my mind, is the very antithesis of art. Rather, petroglyphs are the most basic form of written symbol-based communication. They are communication of great urgency indeed. The earliest petroglyphs, which I find to be the most interesting and significant, are the early hominid equivalent of dialing “911.” “Help! This is an emergency! The matter of time has become transformed into matter itself!” is what they seem to say.

The instant, urgent message of paleolithic man was carved in stone for us to perceive one million years (or revolutions of the Earth around our sun) later. And the message is simply: “There is a planetary crisis. We are being destroyed by our own life giving Sun, due to the collapse of our environmental shield, the EMF that blocked the intense radiation that our threatens our very DNA, and causes acute death from dehydration, sub acute death from radiation sickness, and/or chronic slow death from degenerative disease, unrepaired chromosomal damage, and an inability to successfully reproduce.

The Ice Ages

It is believed that 4 distinct “Ice Ages” have been visited upon planet Earth. No particularly cogent theories seem to have been formulated to explain the phenomenon. My belief is that these ice ages were preceeded by RPGMF events. Further, it is possibly that the severity of a particular Ice Age was proportional to the velocity of the occurrence of the RPGMFE. This raises another interesting possibility. Since there is an intimate relationship between climate conditions and the state of the GMF, there may have been many “mini-Ice Ages” which have defied documentation, each associated with the larger number of RPGMFE's that have been recorded.

The Number of RPGMFE's

The calculation of the number of R's, as revealed in the magnetic history of Earth rocks, has the potentiality for a massive confounding, due to the simple binary data left behind by the individual events. Hence it is likely that the number of R's is underestimated, possibly grossly so. No mathematical pattern has yet been described regarding the frequency of R's. I think it improbable, given the natural of geophysics, that these events are completely random. Therefore a pattern must exist. Given that biophysical events generally follow a bell-shaped curve regarding their distribution, perhaps the intervals between R's also would follow this pattern. Although we current have rather limited data to draw upon, we might simply use the average interval for the known R's, and then divide the total duration of known geological time by this figure, arriving at a new number for the number of events. For instance:

Macrocosmic Recapitulates Microcosmic

Polarity Reversals in general occur over a wide scale in physical systems. However, it is interesting to note that they also occur as a fundamental principle in the functioning of biological systems, especially in neurophysiological systems. Indeed the functioning of the human brain that is now generating these new ideas in dependent upon the depolarization of neurons, which itself is a reverse polarity event.
Cardiac functioning, the beating of the human heart, is characterized by RPE's, at a rate of approximately one per second. And the generation of each heartbeat (itself a RPE) is a function of another RPE-the conduction of an electrical signal from the cardiac pacemaker, the sino-atrial node. And further, the activity of the sino-atrial node, an independently functioning generator of an electrical signal, is in turn the product of RPE's at the cellular level. I suspect this reasoning could be taken further, from the intracellular level, to the molecular, and possibly to the subatomic/quantum realm.

Another familiar example is household electrical current. In AC current we have RPE's occurring every second. In DC current they do not occur, unless the power source, say a battery, goes dead. Then it must be recharged, with the option, perhaps, for a reversal of polarity, although this would be dependent upon the chemical system used.

Anywhere there is a binary system, the potential of reversal of polarity exists. Anywhere there is a waveform, there is a potential for a reversal of the pattern of the wave, an oscillation as it were. In sound, which is not binary, there is an escape from this pattern. That is why perhaps sound, language and music, is infinitely more subtle, expressive, informative, evocative, unlimited.....

You seem to take your starting point from assumptions that the earth's magnetic field is a surface phenomenon. For example,

Tectonic plate activity seems to be responsible for the existence of the Earth's geomagnetic field (GMF).

and

The GMF is a result of the inherent instability of the Earth's crust, primarily the structure of the lithosphere, which comprises the outer 100 miles or so of the Earth's crust.

Can this be verified? The common explanation is that the magnetic field results from fluctuations in the outer core, which we presume is mostly iron.

Also you say

Many “end of the world” scenarios have been postulated over time. A recently popular one is that of the planet's poles shifting or reversing themselves, with predictably catastrophic results.

Actually I haven't seen catastrophic results predicted. The reversal doesn't seem to affect much of anything. Presumably with a weaker magnetic field, more UV could reach the surface, but that hasn't been verified.

Interestingly, though there is evidence for periodic reversal of the field, there don't seem to be corresponding mass extinction episodes.

It is also interesting that the planets with the strongest magnetic fields are the gas planets, which presumably don't have a crust. Do their magnetic fields have a different source than the field of the Earth?

They have left us with a petroglyphic record of this; stone carvings which are especially abundant around the Pacific Rim of Fire.

I am not aware of stone carvings attributed to hominids of that period, one million years ago. Especially in that region. Did I miss something? Artwork of a million years ago would be a big deal in archaeology.

as earthling noted, the gas planets have a strong magnetic field. Our sun reverses it's field every 11 years. Could be 22, can't remember. But it has little effect other then an increase in solar flares.
If the polarity of the earths magnetic field was to reverse, would electric motors still work?

In addition to the Cobb Mountain reversal (1.19 to 1.06 My) there have been the Jamarillo (.98 to .95 My) and the Matuyama-Brunhes (.78 to .775 My) reversals. There is no evidence of any extinction events associated with any of these, even among the less hardy species with less protection of their reproductive materials and even during the faster reversals, the M-B being one of those at 50,000 years.

Since the event is global, there is no 'location'. And because the crucial time is during the midpoint when there is no GMF, the location of the previous poles is irrelevant. The constant wandering of the poles regardless of strength and reversals, and the independent wandering (ie. GMF is not a rigid dipole) supports the claim that location is irrelevant.

The GMF is not driven by tectonic activity. Both are driven by convection currents in the mantle, the former by dynamo action, the latter by friction. Any piezo effects in the crust would be secondary to the friction driving tectonics, far removed from the dynamo activity generating the magnetic field.

Neuronal polarization/depolarization occurs between -50 and 50 millivolts of the resting potential. That resting potential is not zero. The brain is embedded in a dynamic electrical field with variations in field strength at the cellular to entire brain scales, as well as carrying an essentially DC (fluctuating over minutes to hours and typically remaining positive at the scalp with respect to ground) field. Thus the fluctuations occurring in a neuron are more akin to the fluctuations occurring due to sound in air according to your description, oscillations around a value far removed from any zero.

In fact, all EM waveforms occur in this fashion, as they occur across space, which carries an energy potential of its own ("zero point"). The present search for the Higgs boson depends on searching at such a high energy level that there is dissociation from the spacetime energy field, and looking where there is an "energy vacuum" relative to the particles being generated.

The cardiac signal is generated by the sino-atrial node, which is not as you state independent. It is driven by three sympathetic signals with variable periods, the three averaging 0.7, 1.3 and 2.1 seconds, two of these being inhibitory. The variation in three linear functions interacting results in the chaotic/fractal nature of the healthy heartbeat. I emphasize healthy here beacuse it is when the cardiac drivers synchronize and HR loses its chaotic variation that heart attacks can occur. The simplistic pole reversal model you imply would be fatal.

I applaud your recognition of distantly pre-Clovis petroglyphs. Few will even consider their existence. I'm familiar with those that conform to the Anasazi/Hopi designs, as found in such diverse locations and arrangements are the petroglyphs, the Nazca plains images and the Mississippian mounds designs across the midwest US. I'm also familiar with the literature generated by the few enterprising anthropologists that took photos of these various designs to the Hopi elders and asked them to decypher them. They did, including correctly telling the scientists where they were located and how old they were, unasked. Of those with six figure ages, all are pre-Anasazi and cannot be decyphered as meaning anything other than the abstract designs that they are. That is abstract in the sense of representative as opposed to pictoral, probably a necessity considering the artist was working with rocks being rubbed on other rocks on a fairly large scale, making any curves and other fine details impossible. I see no suggestion of any events such as you mention in the 40 or so known petroglyphs between 50 and 150 thousand years old. The oldest known human traces in stone (probably functional rather than depictive) are at least 290 thousand, and are speculated to be as much as 700 thousand, years old. All are in India. None of this age range are found around the Pacific rim. The oldest found there are from Australia and date to 60 thousand years. I do not place the western US petroglyphs on the Pacific rim as they all are found in the high mountain, plateau and canyon regions which are far more tectonically stable than the "Ring Of Fire".

Computer modeling of the solar system during periods of reversal (more accurately, absence) indicate that the interaction of solar wind with Earth's ionosphere would provide less than normal but still adequate protection from the sole danger, increased cosmic rays. This is ionizing radiation and can cause mutations which most often prove fatal. However, the amount that would get through is not much greater than the amount that already gets through. Very recent research suggests that increased cosmic rays would result in increased cloud cover, more rain and cooler climates. These would force even ancient peoples to seek more shelter and thus be less exposed to the small amount of cosmic rays that make it through the denser atmosphere (more H20).

Finally, as noted the GMF is a function of convection of the mantle. There is no "battery" to run down. There is no need for seismic activity to be involved. In fact evidence of multiple reversals taken from single layer deposits on ocean floors show that seismic activity proceeds unchanged throughout, not increasing or decreasing significantly, and when it does change there is no correlation with any changes in GMF orientation, rate of change, or acceleration of rate if change.

All in all a very nice speculative exposition on the subject with many interesting diversions. I enjoyed it. Unfortunately I'm a scientist and feel I must respond to speculations with accuracies when known. Doubly unfortunately for this piece, it's in the family. My uncle replaced Charles Richter (the earthquake scale guy) as president of his seismic activity surveying consultancy upon his retirement. I couldn't go over for dinner without eventually picking up most of a geology degree's worth of knowledge. If you want to find out more, I'll let you explore a bit. Search for 'the first earthquake proof house in California' and the Northridge earthquake. He built the house and that quake proved him right.
