I'm just going to take your word on it ;)

You know I think I'll just put that under the I can't do anything about it so there is no reason to stress about it folder of my brain.

Now is that gonna happen before or after the sun turns super nova in 5 billion years ? If its after i might not have to worry about it right away.....

What exactly happens during a polar shift is certainly a interesting scientific mystery, and could have some bad results for man kind. However, saying that it will create a new reality seems like a stretch to me. The research trying to tie polar shifts to mass extinctions is weak at best. Although, if mundane acts create new realities then a polar shift could as well, but it may not be that much more dramatic.

Maybe one couple, but not 4 is a row... Magnetic Shift is happening right now.

??? what does polar shifts have anything to do with alternate dimentions??? it seems the guy who wrote that was just a science fiction writer that was takeing advantage of a new theory at the time... but yea the poles will shift, the solar wind will somehow still be deflected, and as long as the thing about the landmasses shifting that cause it- doesnt happen (meaning that albert einstien would be wrong) then were gona be ok whenever it happens, which will probably be within the next few thousand years (so dont worry too much, althought the supernova thing will happen in like 3 billion years.... or something like that)

but i dont know that ill bet the farm on einstein being wrong.... its time to build your superearthquake proof, tsunami resistant, reverse-oriented compass containing, superbunker!!!

my brain hurts.
Mine, too.

When the poles shift it's going to really screw up migrating bird patterns. Should be interesting.

But all the talk about alternate dimensions. Well I can understand it in a hypothetical way, but to speak about real alternate dimesions and some of their attributes? That's way beyond my ability to understand. Of course all that stuff comes from mathmatical calculations. And I'm not that mathmatical.

I just think us humans are bonkers.

Time for the physics student to weigh in. :D

I'll start with the side topic of pole shifts. They have happened before and will continue to happen. It happens about every half million years or so, (I could be off on the time frame, I am not a geophysist) and we are about 300,000 years over due. The biggest problems will be with navigation. Planes, ships, and migrating animals will have issues with that. The magnetic field deflects some types of radiation from the sun, so the earth’s temperature will rise and fall as it shifts (and increase the occurrence of skin cancer.) The only plus to any of this is that it’s a slow process, we won't notice any difference in our life times.

The parallel universe thing. I wouldn't worry about it too much. Models are used because they are the best fit for what we observe. They change a lot as more is learned. If any one knows anything about entropy, this was a huge worry at one time. Entropy basically says that all energy eventually is converted into an unusable form. Many physics believed that the universe would suffer a heat death, but now we know that isn't an issue. This sounds like one of those situations to me. The parallel universes out there doesn't necessarily mean there are other actual universes out there (although there could be) but that there existence fits the best mathematical models that we have.

All the theory and math for quantum mechanics is so wacky that we would throw it all away and start over if it wasn't for the fact that the math is such a good fit for what we observe. Mathmatical predictions for quantum mechanics are far more accurate than any other mathmatical models out there. They still aren't perfect and one day we might actually figure it all out.
