Abstract:  GeoMagnetic reversals have occurred rarely in 
earth's known history, and usually deduced from remnant 
magnetic structures within mineral and stone structures.
   
Whether the deductions are accurate or not is not an issue 
at this time for joe.  Let's assume they occured.

The reason for the geomagnetic reversal is alledged to be 
due to tetonic plate movement.  So no reversal is expected 
soon.  The duration of 'no magnetic moment on earth" is as 
well unknown.  What is hypothesized is that, for a while, 
the earth will have no measureable north or south pole.

Basic work, depending upon the compass, will be disrupted 
for an unknown period of time.

But the problem here is the activity of the sun during this 
unknown period of time and its effects upon any residual 
human cultural systems.

During any Maunder Maximum, Coronal Mass Eruptions or 
Ejections tend to occur more frequently.

If CME's occur during the reversal period and 
if they are pointed toward the earth, then there 
will exist no protective magnetic foil to deflect the high 
energy radiation from the CME.

Simply put, the CME radiation will tend to fry all life on 
earth if there is no magnetic deflection barriers up.



                           Now...

There is a minor problem....

The next geomagnetic reversal is said to probably occur from 
3,000 A.D. to 4,000 A.D. which is up to a few thousand years 
out due to the ever weakening magnetic poles.

BUT...

No tectonic plate movement will seem to change or alter 
enough during the remaining years to warrant a geomagnetic 
pole reversal.

So...   what gives?

Unless Tectonic plate movement speed up, and wreek absolute 
havoc upon the earth, something else then, may be 
responsible for the rare event.   But what could that be?

At this time, joe can only dream up a couple or so different 
possibilities

1)  The first is a very hugh solar event that inductively 
forces a change in the polarity of the earth's poles.  It 
would have to be something that would create a hugh increase 
in gauss.  Something approaching temporary magnatar status 
for a short time.

Perhaps something like the absorption or accretion of a very 
large amount of mass with the resultant gravitational 
fireworks.

2)  A near miss by a cruising black hole over the top of the 
solar system causing enormous magnetic disturbances.

3)  Or more modestly a near miss by an iron asteroid going 
over the polar area of the earth, somehow causing a magnetic 
reversal in polarity.  Perhaps even a direct hit by a large
iron asteroid into the earth's magma. 

4)  Or some other internal event within the earth's internal
rotational molten magma.

5)  A combination of any of the above.



Well, that's it for now.  Maybe more later.
