Hi..from my perspective, it wasnt a slip of the tongue. Examining his behavior, I can see that he's nervous yes, but speaking honestly, frankly,
factually and makes no attempt to cover his words or shy away from repeating them. If I genuinely felt he was lying or obfuscating..Id say so...but I
Its probably already been said, that the scientific reality is that the geomagnetic pole has always been moving, shifting and reversing its polarity.
When records began of the changes in polaric density and location it was moving at around 10kms a year and now that has increased to 40kms per year
over thirty years. Scientifically speaking that is 'rapid' change, that is, comparative to the length of solar cycles or tectonic movement or
partcile decay which can take a millenia.
So the word 'rapidly' from this scientific context, doesnt imply a "need for panic"...its just surprising...a micro cycle being scientifically
observed for the first time.
We dont know if that microcycle is 'normal' as there are no records beyond our own in the modern era to determine what 'normal' is for our
magnetosphere scientifically and all we do know for certain and can extrapolate from what we know, is that the speed and location of geomagnetic north
has been changing constantly since the end last ice age.
Its not something that requires 'panic' any more than if I said to you "hey your planets rotating through the universe - backwards!!"
See here: www.nasa.gov...
The map on this page shows how far the pole has been shifting since the 1800's.
Pole movement itself has not dramatically 'sped up' as fiercely the videos poster would have you believe either nor does it imply 'imminent' anything.
We dont have enough data about the paleomagnetosphere to know if the increased in speeds are portents or just processes. As far as the DATA shows..as
far as the geological and geomangentic emperical evidence can show at this time...this is a common event.
On this video, the scientist is responding to a specific question that asks what would occur in the event of a complete *magnetosphere collapse* - a
question he couldnt reliably answer as we simply dont know except to point to Mars as an plausible example.
While absolute collapse may be an inevitable part of the entire magnetic cycle of our planet, complete collpase it is a completely different 'thing'
to geomagnetic pole "shifting" and reversal pauses or "minor collapses".
The difference is like that between twirling in a loose skirt and having the back slide around to the front....and taking it off altogether.
If its just twirling, the skirt slips around, it might slip down a little, a thin bit might show..but it, the skirt remains in tact and only the
fabric's density changes.
If its off..its gone..simple...and there doesnt seem to be a 'putting it back on' process visable at this time.
If the magnetic poles reverse, that doesnt automaticalyl equate with a collpse of the magnetic sheath...the mangetic polarity changes, but not the
existance of the sheath itself.
A complete or absolute collapse of the magnetic field or sheath, is an an event which would leave our *entire* planet completely bare, exposed to
cosmic interference for an indefinate period of time. The geological records we have dont show such a global event has ever occured here on earth.
In order for the magnetosphere to collapse entirely, the inner core of the planet itself would have to cease all rotation...completely. If that were
to occur, in very short order cosmically speaking, our atmosphere here wouldnt exist at all, so it is not something 'survivable'.
There is no record here on this planet of that ever occuring though there is enough evidence within our solar system to suggest is has occured
elsewhere and evidence to suggest the sheath can be punctured..
What the records do show reliably is periods of geomagnetic instability and change, with high energetic particle activity and localised increases in
magnetism - changes - changes that are testable and present in the soil and ice in some locations.
The only factual and testable science available to determine what *might* happen in the event of a pole *reversal* is the geological and geomagnetic
records of what we are assuming are past reversals, and what they show is circumstantial and the truth of those records is still based on scientists
making the correct assumptions and interpretations of the records.
The closest event geologically speaking that might give clues to impacts of a temporary absence of our magnetic sheild is evidence that shows that an
event around 120,000 years ago (most likely a close by supernova) that appears to have punched a hole right through the magnetosphere and allowed
energetic particles to embed into the soils of the northern hemisphere. By studying changes to the land around those sites, to the wildlife, trees
pollens etc..we can build a retoactive picture..but cant 'proove' anything for certain.
If it had been a global collapse of the sheild at that time even for a microsecond, the same particles would have been found in the southern
hemisphere as well, in Antarctic ice cores, but they werent.
This shows that whatever occured, the hole opened quickly and was closed very quickly. It also suggests that the event most likely occured in the
northern summer as there was no icefall to absorb the particles or slow the rate of their decay.
By studying the cycles of the magnetosphere we know a collapse of the sheild, partial or full, is a possibility, its by no means a certainty.
It depends greatly on the dynamic interactions between or planetary core and the shield itself.
It also could depend on our human technological and chemical impacts and interactions within our upper atmospheres as well as we simply dont know the
long term effect of our 'noise' to the equalibrium of the sheaths own frequencies.
The lifecycle and interactions of the inner core with the upper atmosphere and magnetosphere and our impact on that is an area of study only now being
researched in earnest.
So...that all said....total geomagnetic shift or 'pole reversal', can be viewed less hystericaly as being a natural part of our planets life cycle
rather than a cataclysmic earth ending event.
To quote from the link
As regards a polar reversal or 'pole flip':
"Sometimes the field completely flips. The north and the south poles swap places. Such reversals, recorded in the magnetism of ancient rocks, are
unpredictable. They come at irregular intervals averaging about 300,000 years; the last one was 780,000 years ago. Are we overdue for another? No one
occured before will occur again - life continued on before during and after it.
As regards a complete collapse and its affect, a quote from 'hypography':
"Evidence indicates that in Mars' distant past, it may have had a strong enough magnetosphere to deflect the solar wind coming from the Sun. However,
about 4 billion years ago Mars' planetary dynamo ceased, leaving only remnants of the planetary magnetic field to be frozen into magnetically
susceptible minerals. Over time, most of this material was reprocessed through various geological events leaving only sections of the ancient southern
highlands with remnant magnetic fields. Because of this, the solar wind interacts directly with the Martian ionosphere and thus the Martian atmosphere
has been slowly stripped off into space, although the exact amount lost remains uncertain. Both Mars Global Surveyor and Mars Express have detected
ionised atmospheric particles trailing off into space behind Mars"
Occured - All life on Mars..died.
So...its up to you if you want to panic or cause panic in others about this subject...but I wouldnt be wasting my time fearing. Its really really
really important though to know the subject matter before projecting fears about it. People have enogh to cope with. I dont think the videos poster
has any real clue.
