Magnetic Reversals

They’re the scars from the previous relativistic bombardment which occured shortly after the prior human civilizations radio frequency transmissions passed the approximate 50 light year mark.
That puts us about due for a pounding... ;-)
No, a magnetic reversal does NOT happen around once every 13,000 years. Their interval, in fact, is highly irregular, perhaps even chaotic. The last major reversal was 780,000 years ago, although there were temporary collapses in magnetism since then, which I presume is what this article is calling a reversal. Some reversals were millions of years ago, some happened within several thousand years of each other, if you count these momentary collapses as reversals.
The magnetic field is currently weakening; this in no way suggests a major or minor reversal is coming. At the current rate of collapse, it would take over 1000 years to completely collapse, and such variations are completely normal outside of any long-scale trend.
1958?

Inductive resonance? How iron-y is that country and how much iron does the peat contain?

There’s been some stuff on the web, and not the wacko sites, that mention a weakening of the polar magnetic fields which is believed a prelude to a full reversal.As for 2012, I don’t speak Mayan so I can’t say, but weirdly, I do remember as a kid reading a comic strip in the SF Examiner that had a story line of the consequences of a mag shift. That was in 56. I remember cause I was visiting my aunt in Albany Cal that summer and I thought the Examiner’s comics were more interesting than those in my NYC papers. The things that stick in your mind.
Lake Mattamuskeet, the largest natural lake in North Carolina, is a Carolina Bay. Legendarily, it burned for “13 moons,” or a little over a year. I’m not absolutely certain, but I believe Mattamuskeet means something along the lines of “bad place where the ground burns.”
I’d heard that the Barringer [sp?] crater in Arizona has a similar Hopi Indian legend surrounding it, that a god came down there on a pillar of fire. Very interesting in as much as the commonly accepted dates for humans in N. America is about 25,000 years to late for that to have been observed. Either there WERE people there to observe it, or the Hopi were a lot more intuitive in noodling out what it was from observation several thousand years ago while we were still debating it being a “crypto volcanic structure” into, I believe, the 60’s...
The coastal plain of NC is essentially a huge delta east of the “fall line,” which runs NNE to SSW in the vicinity of Raleigh, roughly parallel to the general coastline over 100 miles away. The only known deposits of note that I’m aware would be phosphate ore, and there’s a great deal of it in the areas in question. There are phosphate mining operations in many coastal NC counties.
Yes, and the time for the ~.75-.9C projectiles to make it back here puts it just abou
Wasn’t it more like every 200,000 years?
Is there any chance this is related to the article the other day about “Comet Causes North American Die-Off”? It was saying that perhaps a comet hit 13,000 years ago, resulting in shock diamonds found on one of the Channel Islands in CA, and a layer of black soil that is found over broad swaths of the continent, and the die-off of large mammals like mastodons. Any chance it was the same event?
So that kills the theory of inductive resonance.
How would fire, phosphates, and peat bogs leave great big holes in the ground? Across half a state?
It'll take me a few minutes to cogitate around that one, but I'm sure I will. Mama always said I could tear up an iron anvil with a rubber mallet.
The day I got ahold of LOX and liquid nitrogen, I proved her right.

I agree
I don't know...too many theories, make my head hurt. My kitchen-physics suggests a magnetic disturbance, liquifaction, resonance effect.
The only thing I knows is: it’s all George W. Bush’s fault! Oh, yes, and we must institute a new tax to counteract our role in producing this effect. (/sarcasm)
