Ah! Hence the as sumptions.

Okay wow that is bad.

Assume assuming assumptions <- I am so naughty.

but if You put some Letters in Italic
You can dance your Ass of as long as You like ;)
OK, can we get back to Topic. I like conspirassy Theories

He who dances with the Masses ;)

Yes, let's get back to the completely sane discussion at hand.

Actually I got interested and did some googles. https://www.uwgb.edu/dutchs/pseudosc/flipaxis.htm has some neat relevant data on what it takes to change the axis of the earth!:
Quote
The amount of energy contained in the earth's rotation is pretty large: 2.1 x 1029 joules. You'd have to supply an appreciable fraction of that to change the earth's rotation in any major way. To put this number in perspective, a megaton is 4 x 1015 joules. You'd have to supply about 5 x 1014  megatons, or about 100 million times the total nuclear arsenal of the Earth. So we can see that the science fiction theme of a nuclear blast affecting the earth's rotation is just plain impossible. The kinetic energy of the earth in its orbit is about 2.7 x 1033 joules or about 10,000 times its rotational energy, so the entire earth's nuclear arsenal could hardly affect the earth in its orbit even if we could somehow deliver the energy effectively.

However, this is apparently also a thing:

In addition to apparent polar wander, however, there is a real polar wander. The crust of the earth can slide over its plastic interior in response to mhoop imbalances. The rotation axis of the Earth stays fixed, but the crust as a whole can move relative to the poles. The term is still a misnomer - it's the crust that moves, not the poles.
For all practical purposes, that would have the same effect as far as we're concerned. So, how easy is it to move the crust around to different places?

... probably still not very.

Edit: superscripts don't copy well.

owowwo, Relax. :)
The rotation is not gonna change or reverse, thats impossible !
its just the Polarity that is gonna change/reverse. North---> South and South--> North thats all

I assume its impossible (and it's not likely to happen).
The Crust IS moving constantly, yes,  but with a mere 1 Millimeter per Year

with a very, very slow dance

I'm relaxed, it's a funny discussion.

But anyway, that's magnetic pole reversal, which is a thing that happens, yes. The original topic (as the title shows) is geographic pole reversal. Which is not a thing that happens, except when planet-sized objects hit each other. It's not impossible, though; see Venus and Uranus. But yeah, that's... unlikely, to say the least, and the least of our worries if it does happen.

ahhh, OK,
then I got it mixed up and assumed something else
 my posts were about the Magnetic Pole reversal.

Hmmm, I wonder if this map qualifies as Geographic pole reversal.


It's at least pretty funny
