Anyone have any info...input on this subject. It is one that I find fascinating. There is so much controversy on when it will happen and what the consequences will be. I've heard anything from volcanic eruptions worldwide to lost animals who use the earths magnetic field to guide them in their migration. I've also heard it can happen fast..like in 50 years the north pole will be somewhere in Tahiti. Again so much controversy can be said for it.

It happens over a longer period of time than 50 years. It can be quick (geologic time), say 1000 years. But it can happen every anywhere from every 100,000 years to every 1,000,000 years. Its quite interesting though... no mass extinctions or otherwise strange "catastrophes" like these new age prohets are talking about have been seen in the fossil record.


Its a really interesting subject though... Very interesting indeed :)

The actual time it takes to complete the reversal can take anywhere from 1000 to 8000 years with the average being about 5000 years. The reversals occur every 100,000 to 800,000 years. Pretty unpredictable if you ask me. I am more interested in what causes the reversals.

Tristan is right about the lack of correlation between reversals and mass extinctions.

Everyone is quick to assume it's the time is near...Although I am not one to jump on the bandwagon....the earth is changing in many ways. I heard that the reversal of the poles are overdue as well....just heresay ofcourse but it is interesting though.

I think the link I posted earlier suggested that it has been 700,000 years since the last reversal.

WERE ALL DOOMED,

i've say programs that said,

the next catastropic super sunamia is over due

the next caldera super volcanic eruption is over due
every 600,000 years

the next expected large meteor is over due

ice age...

the return of the Jedi...

and so on

they will all come at once like the bible say's >> armagedon thing

Human sacrifice, dogs and cats living together - mass hysteria.

Well, the tidal wave can cool the volcano, and the meteor can be deflected with Jedi mind power, and we're all set!

Oh, you forgot the global pandemic that's supposed to wipe us all out... we're overdue for that one too, I understand. We're also overdue for Nostradamus' end of the world, but maybe his date was a little off.

Some say the world will end in fire,
Some say in ice.
From what I've tasted of desire
I hold with those who favor fire.
But if it had to perish twice,
I think I know enough of hate
To say that for destruction ice
Is also great
And would suffice.

I've got a meeting tonight at my Stonecutter's lodge. I'll ask around and see when the guys think we should flip the switch again. Last time we did it, it triggered a minor earthquake in the Alsaice-Lorraine, prompting France to immediately surrender to Belgium. Belgium was busy flossing it's teeth and didn't get back to France in time, so they surrendered to Liechtenstien.

We sent a Special Envoy (Jerry Lewis) over there, and he straightened the whole thing out. ;)

How's Steve Guttenberg doing thses days?

Steve's not doing so well. Sadly, last month he had to close The Steve Guttenberg Fantasy Ranch due to lack of funds. It seems people just didn't find his stories about working with Ted Danson to be all that interesting. We're going to pass the hat for him at the lodge tonight.

I hope you get the needed funds. Would hate to see him have to get chained to the Stone of Shame.

Me too, I really don't want to see that back hair.

True. He should do rapper chicks a favor and shave all that off so the less fortunate of them can have suitable weaves.

Who the hell is steve guttenberg?

Ok, a tad bit off topic guys.... take it to free thoughts.

the magnetic field of the earth is something that has interested me for a long time now. there is so much controversy over whether the field will actually decline until nothing is left (as some scientists say happened to mars), or whether the magnetic field will reverse.

i believe the latter option because there has been scientific evidence on the seafloor--the land that is created by mid-ocean riffs alternate in the magnetic pole directions. that evidence MUST be solid. if the reversal happened before, why wouldn't the field flip simply do as it did in the past?

i just watched a program concerning this the other day. there was a geologist who observed the previous magnetic reversals by taking samples in huge sedimentary rock. he said that towards a reversal, the compass moved up to 6 degrees per day in the opposite direction. that is quite amazing.

at the current moment, there is a spot in an ocean (that is increasing in size, i believe) that already has no magnetic field.

what makes me wonder: what will be the effects on us (meaning humans, animals, whatever) due to the declining magnetic field? how will we react to this shift? the frequency of the earth is decreasing as well, and i wonder if our brains will have unusual experiences because of this freqency change?

I live in Canada and noticed the Canada geese didn't fly south....I have seen them in hordes flying everywhere at one time....it's kind of scary. Like they didn't know where to go. Apparently this is effecting alot of wildlife already....ducks....whales....dolphins....it doesn't take a genius to figure out that the earth is changing in many ways.....and fast.

Well, it really isn't 'all hype' as you think.

Records are for at least 171 times (a dipole reversal).

William Topping found 70,000 proton track per cm^2 in worked churt and
flint tailing at a PaleoIndian site what is now northern Michigan.

Dipole reversals are not simply a pole flip. The sun is an excellent
model or indicator of what can happen on the Earth.

The primary phenomenal structure in any 'live' planet or star is a
large scale flux loop system. For example the Sun's primary flux loop
is in the E-loop mode when the sun is at solar minimum. During the
E-loop mode the Sun behaves as if there were a large scale toroidal
current and the sun displays the properties of a magnetic dipole. When
the sun begins to approaach solar maximum the magnetic dipole field
begins to weaken and then is gone altogether. During this phase the
sun is in the H-loop mode. At this time the sun displays the
properties of a large scale electric dipole structure.

If the Earth's main flux loop structure (electromagnetotoroid) or EMT
for short were to go through a similar process then there would be
considerable damage to the biosphere. Charged particles would be
accelerated poleward; protons to one pole and electrons to the other.

Another feature is that the Earth's seafloor spreading zones are in a
1:1 correlation with dipole reversal events. In other words it might
be possible to discount this but the simplest explanation is that there
may be a direct correlation between sea floor spreading activity and
dipole reversal events.

In studying flux loop systems over the years I've discovered that an
EMT in a compact mode can generate copious quantities of neutrons in
the core. That's right, you're likely to choke on this but the same
mechanism which can cause a dipole reversal; which causes a pi/2 radian
rotation of the flux density vector around the axis of the Poynting
vector on a flux loop is operative during the H-loop mode. This
process produces quantum scale copies (structurally) of the main flux
loop system. These quantum scale flux loops are exactly the same thing
as neutrons. So it is that the Earth's EMT during the H-loop flux
mode will produce hundreds of billions of tons of neutrons per second.

This means that there really is a means for mass creation/production
and the consequence to a planet is that it will undergo gross expansion
after each episode of mass production in the planet's core. If one
just looks at the New World Hammond Atlas (at your local library)
they've done an excellent job of mapping the sea floor spreading zones.
When looked at all at once one gets the distinct impression that the
Earth has expanded and the sea floor spreading zones are the massive
stretch marks.

In fact, the biosphere has undergone tremendous devastation again and
again and the primary cause of mass extinctions is a major expansion
episode.

There are a number of websites which have information on Earth
Expansion and even though geologists have the evidence for Earth
expansion staring them in the face they refuse to accept the facts.

My own research has allowed me to discover the mechanism for mass
creation in the universe. This is hard to believe especially if you
were raised with the conservation law mantra drilled into your head.

In fact, conservation laws only express that energy and matter can be
transformed one into the other without gain or loss. The truth of the
matter is that they say nothing about the origin of mass in the first
place. Conservation laws don't address the issue of the origin of
matter. Some think that the mythical Big Bang answers the question of
the origin of matter but it doesn't. First, it doesn't because it
isn't a belief that can be made subject to verification. Second,
that's exactly what it is - a belief. It's not valid or legitimate
science.

:eek:

Monkeys laugh to signal their fear. There is serious research in pole shifting going on, it's not a laughing matter, and Madscientist1 knows what he is talking about. Magnetic Pole Shifts come around just like any other season except you're talking about seasons that are several thousand years apart. When these seasons begin, some shifts happen very quickly. Within a few hours. Some shifts are very slow. It's actually a very complicated subject and I believe Madscientist1 has gone beyond most of you on this one. "Throwing Pearls to Hogs" :m:

I have read of magnetic pole reversals and the conscenses seems to be that we may
be beginning the process now or that the magnetic reversal is likely to begin within a
few decades. What I have a problem with starts with the suggestion that seafloor
spreading events are linked to neutron creation (exactly how, again?) and the subsquent increase in mass and size of the earth's core. Why wouldn't electrons
and protons be more likely to be accelerated toward the poles during the stable mode
than during the process of a reversal when the fields are all scrambled, for example?

Monkeys laugh to signal their fear.

Damn right. What else can I do but laugh? There are so many different signs foretelling how much shit is gonna hit the fan in the next few years. I dont laugh because I think its BS, I laugh because I've already accepted the fact that the world will be a very different place in the years to come. There are troubled times ahead. The fat lady hasn't just sung, she's into her second encore.

Keep a smile on your face and carry a big knife.

Amen to that SCRAMBLE......what can you do...life must go on....it's all part of mankinds revolution......I guese one can never take what you can't change too seriously. I'm not just going to sit around waiting for the other shoe to drop....I'm GOING TO LIVE!!!!! LIVE!!!!!! LIVE!!!!!!!! HA!!!!!HA!!!!!!

Another feature is that the Earth's seafloor spreading zones are in a 1:1 correlation with dipole reversal events. In other words it might be possible to discount this but the simplest explanation is that there

dipole reversal events.


Let me explain the seafloor pattern a bit. The Mid Ocean Ridge (MOR) spits out basalt on a regular basis. Basalt contains some iron bearing minerals such as magnetite that record the current magnetic North when they crystalize to a solid rock. The MOR is putting out new crust at a fairly regular rate displacing the older ocean crust outward in both directions like a conveyor belt. Since the ocean crust is destroyed at subduction zones, we only have a record of the last 300 million years of reversals. The timing of reversals is somewhat irregular. Whereas the output of oceanic ridges occurs at a more consistent rate.

yes, seafloor spreading shows this. another quite interesting way to observe the strength/direction of the magnetic field of earth from the past is pottery. yes, pottery. only baked pottery, however, because after heating, the magnetized pieces realign with the magnetic field of the earth. this can show some interesting history on the magnetic field of the earth the time the pottery was baked.
i saw watched this pottery detail on some NOVA program, i believe.

I have read of magnetic pole reversals and the conscenses seems to be that we may
be beginning the process now or that the magnetic reversal is likely to begin within a
few decades.

I posted a link explaining this earlier in this thread and here it is again.

http://www.geolab.nrcan.gc.ca/geomag/reversals_e.shtml

Just as an aside - Why doesn't anyone read links on this site? I'm not spewing bullshit like so many on the forum, and I don't link stories with no scientific credilbility.

http://www.geolab.nrcan.gc.ca/geomag/reversals_e.shtml
hmm a very interesting article, indeed. so everything is unpredictable, which we've seen in the form of seafloor spreading magnetism evidence (the years between each flip varies).

i find this point particularly interesting:
A reversal does not proceed in a uniform fashion. Large and rapid changes in direction and intensity are punctuated by periods of little change. During some transitions the field starts to change but then rebounds to near normal before the reversal finally goes to completion.
the pole flip will eventually occur, but it is fairly unpredictable. this is good to know. so as we see these changes occuring now, it could still go back to appear normal.

but i agree with madscientist1 and scramble: we're in for it. it doesn't matter. let's get used to it.

Princess, your link was to one site with one opinion. The length of time for the reversal
to complete varies a great deal and is a subject of debate among scientists, not a given. Computer simulations involving 2000 hours on a Cray supercomputer done in
1995 predicted about 1200 years. It was a front page story in Nature magazine. Some
studies of rock formations, I think it was in Oregon, suggested much less than a hundred years for one reversal. NASA's website states some reversals take less than
a hundered years to complete. As I said, there is debate about the timescale and
there seems to be much variation from one to the other. The debate is among respected scientist and not "crackpots."

The Earth's magnetic field is created deep within our planet's outer core through a complex, self-sustaining interaction known as the "geomagnetic dynamo" (see What Drives Earth's Magnetic Field?). (http://www.pbs.org/wgbh/nova/magnetic/reve-drives.html) In the 1980s, Gary Glatzmaier, now at the University of California, Santa Cruz, and Paul Roberts of the University of California, Los Angeles, began work on a computer model that simulates this interaction. By 1995, they had created a model that not only created a self-sustaining magnetic field (the first to do so), but after simulating the passage of 36,000 years, the field it generated spontaneously flipped.

link:http://www.pbs.org/wgbh/nova/magnetic/reversals.html

The length of time for the reversal to complete, as in shift from pole to pole, not the
time between reversals.

I don't want to dismiss computer models but let's not confuse models with fact. The factors involved with the Earth's magnetic field are incredibly complex. Not everything can be simulated with a model simply because we don't know enough about the various inputs yet. And why depend on models when we have 300 million years of historical record on the seafloor?

Gee....we live on a planet. This planet is replete with magnetism, plate tectonics, volcanism, storm systems, etc. Plus, the solar system we reside in is replete with solar winds, solar flairs, sunspots, background radiation, comets and asteroids precariously within the possibility of crashing into us and killing us all....all of theses things can, at the very least, mess up our cellphones and cable for a few minutes, at the most, cause an extinction level event. We have no control over these things. Get over it. We are simply residents here....shortlived ones at that. It's amazing we have lasted this long.

This planet, whether from pole shifting or global warming or, hell, even alien conquest, isn't going anywhere for a long long time. We, as a species, may be totally screwed, but I for one don't worry about the planet. It will do just fine and another species will come along to take control once we're out of here.

I can understand the scholastic study of this phenomenon, but the doom and gloom that's often associated with it seems to be a waste of brain cell activity. Again, it's pointless to worry about something that A. you can't possibly control, B. can't possibly predict, C. can't possibly have a clue as to how to prepare for it.

??? I discuss things I find interesting, not because I am worried about them. Perhaps
it's just because I am not the worrying type. Mostly, what I find interesting are things
that are not altogether cut and dried, but are not completely understood and have
a variety of viewpoints. Not much fun discussing something that everyone is in complete agreement with. But please, no politics or religion. I said discuss, not argue.

Princess, your link was to one site with one opinion. The length of time for the reversal
to complete varies a great deal and is a subject of debate among scientists, not a given.

Indeed it is one viewpoint. I wouldn't call the Geological Survey of Canada's writings "opinions". These people are professional scientists. They don't publish or endorse their own flights of fancy.

Princess, I never suggested they published flights of fancy or weren't "professional
scientists." I said that was one site with one opinion on the length of time past
reversals have taken.
from the GSC site:
"Although fast by geological standards, reversals are by no means quick on the human time scale. They take roughly 5,000 years, with estimates ranging from 1,000 years and 8,000 years."
That is an opinion not necessarily shared by all professional scientists who study the
geological record. There is controversial data from the lava in Oregon that suggests
one reversal advancing at up to 6 degrees per day. And yes, the estimate was from
professional scientists. Many sites, including NASA's, indicate some reversals take
less than 100 years, also by professional scientists. Do you understand what "subject
of debate" means?

Do you understand what "subject of debate" means?

Indeed I do and it's obvious that we both understand the art of smartass.
