Here is a very good NASA article about the shifts in the magnetic poles, including the evidence you mentioned at the mid-Atlantic rift.

Can you explain how you equate stories of large disasters to magnetic pole shifts? Because a magnetic pole shift doesn't have to cause any disaster at all. Or did I misunderstand your point?

Which ancient cultures were dependent on magnetic compasses, then? Unless you spend a lot of time messing with lodestones you aren't going to notice the field lines kinking.
If you were above the arctic or antarctic circles you might notice that the aurora have vanished. Of course you'd have to trust the word of your great, great, great, great, great (how many "greats" do you need to make up ten thousand years?) grandfather said about seeing Northern Lights. The only way ancient cultures would have documented the changes in the Earth's magnetic field is if; a) there were effects we haven't discovered yet, of magnitudes greater than the effects we expect, and; b) what happened, happened swiftly enough so it could be understood and documented as an event. If farming got a little harder and temperatures got a little higher over a period of ten thousand years it would be very difficult for anyone to detect the change, as against all the faster and greater changes occurring across a human culture. Farmland gets depleted in much less time, erosion is swifter, and the effects of slash-and-burn agriculture are blindingly fast against that sort of time scale.

And oh by the way. As I understand we don't have a "notion" of a pole shift coming in the near future. We have an _expectation_. To buttress that expectation we have observation of the "baked-in" magnetic record of undersea lavas, and we have the observation of current drift and increasing "kinking" of the current field. The last is an observation, one that could be made independently by anyone with a compass and time (the last correction was, what, fifty years ago?)

What intrigues me about Glatzmaiers modelling of the pole shift is that they've been able to get a 'one off' magnetic pole reversal to occur but they've yet to get any kind of cyclical effect. For a cyclical effect (eg a shift on average every 300,000 years) the system must have a long range cyclical phenomenon which they have yet to model? This raises the question as to whether it is external (ie solar system based) event that triggers the shift or an internal (ie within the earth) event. Who knows? I think its important not to link a magnetic pole shift with any kind of disaster theory or flood legend: I've never read of the magnetic pole shift being associated with either? It seems too that present day scientists don't identify a disaster element with it either? Interesting to be around when it does flip over...or perhaps not! What I think is very interesing here though is this concept of the 'modern rendition of a myth' as alluded to by A.DIM. If a myth or archeological text describes something that was not known by the scientists of the day, and then our latter day scientists confirm the hypothesis...then surely that myth is no longer a myth? So my next question is: "What is the earliest historical statement or discussion that cyclical magnetic pole reversals occur on Earth?" This kind of leads to the question about the source for Cayce's 'knowledge' about pole shifts? Cayce was clearly wrong in terms of the dates he stated for a pole shift but I wonder what emboldened him to talk about them in such a 'matter of fact' way in the first place? It doesn't matter whether he was or wasn't a genuine seer: its a fact he was talking about 'pole shifts' in the 1940s? So I wonder whether the cyclical magnetic pole reversal data was available then (and not just a wandering around of the pole which historically is well known.) Either way, a very well read chap to raise it as an issue though. So it would be useful to find an early reference within the field of paleomagnetism (the study of the Earth's past magnetism according to the NASA site!) which talks about cyclical magnetic reversals. Ditto the earliest allusion to the phenomenon from the arcane would be of interest too. Thanks again to everyone for chipping in - I'm glad the documentary I saw wasn't something I made up!

Not that the ancients measured electromagnetism. The OP's list is astronomical in nature and touched on the 12K year cycle that is half a Great Year. I wanted to clarify the association, though now I'm unsure I did. ![]()

So the myths have no relevance to shifts in the Earth's magnetic field. Check.

I think the only way we can ever get to the bottom of what was going in our distant past (eg archeoastronomy) is when we can match up a mythical statment or legend from the past that was imparted by the 'gods' and which was beyond the science of that time, and yet we only now know to be true. It looks like for example, that Edgar Cayce could easily have picked up on pole shift reversal from prevalent theories of the early part of the last century and then used it in his readings (whether 'consciously' or not.) So far I've not been able to come up with an archeoastronomical legend that fully backs things up to the level needed (and of course most on here will say I never will!). I think the closest things I've come across are the Doggon tribe and the star Sirius B. Similarly the legend of the destruction of Tiamat is interesting and one I might raise on a seperate thread to see how the BAUT crew tackle it! A quick thanks again for everyone responding and especially for the courtesy of the links. {I'm still looking at the magnetic reversal 'bar code' pattern for earth and trying to assess whether it is cyclical or not (aside from the eons where nothing happens of course) - if I had a bar code scanner I'd like to see what price I'd get for the data!} Thanks.

Big Blue,
One piece of friendly advice. Discussions of mythology are allowed by the rules of this board. But be careful extending that into religious discussions, that starts getting on a slippery slope. You might want to read through the FAQs and the rules.

Um...
The two small moons of Mars were described by Jonathan Swift on the basis of a then-current conceit that since Earth had one moon and Jupiter four, Mars must then have two. That two such moons were eventually discovered does not in any way validate his method. We all know, for instance, that Jupiter has many more moons than the four big "Galillean" ones. This was the point of the "Zeus" comment. An ancient culture can accurately record the location and date of a nova, regardless of whether they call it a new star or a dragon in the sky. The leap of illogic is in deciding that since an ancient culture was able to observe a nova, they also must understand stellar fusion.

Noted and my post has been edited accordingly: apologies. I'm only interested in finding scientific information that might be ahead of its time regardless of source or contextual belief system. I'll stick to myths. Thanks for the heads up.

This in turn tends to limit the corresponding science to that which is on either an microscopic scale (and thereby presumably not relevant to this board), or astronomical one (which I hope is), I'm particularly interested in archeo-astronomical observations that have been made concerning astronomical/cosmological events that are beyond the naked eye and/or a simple telescope, and thus could not have been witnessed terrestrially in the ancient past. As stated, the Tiamat and Dogon myths are probably the most interesting ones I've come across. Regards, Big Blue

How so? Guessing at the number of moons on Mars based on the observed/assumed number of moons around Earth and Jupiter is to me everyday playing with numbers whatever the period of history. Its a bit like the Nuclear Shell Model approach...look at the data, guess a pattern, see if someone proves you wrong. To me this kind of observational guessing is standard scientific practice for that period, and of course its still in use today.

I don't accept Swift's guesswork because the observation of the number of moons around Earth and Jupiter was (as far as I know) available data at the time. If for example he could have quoted the material composition of the (then unknown) planet Pluto and then we wait until now for NASA to back it up...then that's the kind of anomaly I'm seeking. Similarly, any archeoastronomical observations on planet structure and their moons etc that is beyond guesswork and beyond observations of the time is the kind of thing I'm interested in. I just don't rate Swift's observation as being particularly anomalous or outside of his time, to me its just a projection of the known available data. As for The Dogon, on the contrary, the backstory for that is specifically that the tribe in question could not have had any 'available data' to go on with regards to the orbits of Sirius etc. I'm not convinced its been 'that' well debunked either: you can always debunk anything you've decided you don't want to believe in just as well as a believe in anything arcane that you want to believe in. For me the 'evidence' has to have been cast in stone a long while ago (literally if possible) such that it can't be tampered with today, and its meaning only interpretable with today's scientific data. For me, The Dogon myth is unfortunately too recent to stand aside from a possible contamination of the source material, and I can't see how that can be fixed. The Sumerian Cosmological stuff is more interesting because the source data (ie clay tablets) cannot now be corrupted; misinterpreted - yes, but corrupted, probably not. I hope that clarifies a few things.

Why the assumption that there are anomalies to be found?

Why indeed then, the assumption that there aren't? To me there is only data. I'm interested to see whether any of it is anomalous because that is what is of interest to me at this moment. A lot of new discoveries are made only when data is observed to anomalous.

Also, in cases where examination of the evidence produces no support for a claim, would you consider this justification for disbelieving the claim, on account of the results of your examination of the evidence? What about when examination of the evidence produces support for belief in a counter-claim, that contradicts and rules out the original claim? Would disbelief in the original claim be warranted in that scenario, or would you prefer to maintain a non-rigid agnosticism? ![]() |

Fair enough and my post has been modified accordingly, not that it really matters, as the issue was only raised as an example of archeological data that is claimed by some to be anomolous for its time.
Understood. Accordingly, let's end any further discussions between us on this matter. Thanks for your comments though. Similarly, I've found out what I needed to know concerning the pole shift reversal theory and its origins commencing at the start of the last century. so thanks to all above for the links to the supporting data. Apologies for where I've gone off the permitted topic boundaries especially if that has caused any offence.

Let me though rephrase my quote then as follows: "An examination of the evidence is better than the adoption of a rigid belief system which would preclude any examination of the evidence in the first place." This is definitely a belief system I do hold. Evidently, there are a considerable number of 'preclusions' associated with discussion on this board, and which I have inadvertently failed to comply with thoroughly enough: I should have checked the FAQ no doubt and so do apologise again. But its best I withdraw forthwith: that's another 'belief system' I have concerning these matters. Regards, Big Blue

You're calling Swift's guesswork--even though you do not know that it was. You're assuming that because it is outside the scientifically possible, for the time. So, why couldn't the Dogon stuff be guesswork? Nevermind the contamination issue, I mean, the point in contention is just that Sirius has a companion--it's the brightest star in the sky, of course there's two of them there! That's about as simple of a leap as what people say Swift did (I don't think they have conclusive evidence that's what he did).

Fair enough too, if you are saying that The Dogon 'myth' is in fact totally deductable based on naked eye observations that can be made of the Sirius star system from Africa; believe it or not, based on the high standard of astronomy associated with this board, then that's actually good enough for me at this stage. The myth is always stated as not being possible though - hence why I raised it here. I was actually hoping to get plenty of other of so-called archeo-astronomical 'anomalies' that I've read about raised and then batted away by the astronomers here, as succintly as possible. But best leave it be I reckon, I know when I'm singing out of key. Regards and anon, Big Blue

I fully recognise that you guys on the board have just about had it with all kind of weird postulations and I was trying not to go too far off topic and take you backto places you've been (and don't want to return.) At all times I'm seeking the hard science that can knock all this stuff back, especially as I don't like loose ends! What I like about astronomy is that it is reasonably steady-state so we can always have a good idea about what was and wasn't 'knowable' for pretty much any era of mankind. The Doggon myth has always interested me because in principle it hangs together reasonably well; well as much as these things probably can that is. Cheers, Big Blue
