Magnetic reversal hints in Earth's core

The Earth's magnetic field may flip every few thousand years due to lopsided growth of the planet's core.

Scientists investigating the phenomenon of magnetic field reversal have determined that these shifts are likely to be connected to the growth of the core. The findings also suggested that the next reversal could be underway and that if this happens it could prove disastrous for power grids and communications systems.

"What we found that is interesting in our models is a correlation between these transient [shifts] and reversals [of Earth's magnetic field]," said Peter Olson of Johns Hopkins University. "We kind of speculate there is that connection but the chaos in the core is going to prevent us from making accurate predictions for a long time."

"Lopsided growth of the Earth's core could explain why its magnetic field reverses direction every few thousand years."

And without cell phones (which is not really a big of a deal but also without any gudance systeme for airplaines and radars which is bad ... and no missiles control ...and this is perhaps good

It happen before, it will happen again. It also happen while humans were on this planet, so basically it won't be so bad if we prepare for it. Harden our infrastructures to electromagnetic pulse that will be generated by the pole reversal and we will be fine. Of course we got to compensate for the mix-up of the weather that will happen on the planet. That would be bad, very bad... magnetic field collapse that protects us from the bombardment of particle rays from the sun. We would end up being stripped of our atmosphere and well... kiss our planet goodbye!

this realy makes perfect thinking in world cycles with exception of sum astroid smacking the hell out of us (the planet) weather,evirmental even in evolution when you take in the count of planet rotational stress and gravity now add in the core movements an plate drifts, volcainos,weight surge, planet contrast shaping altogeather well hell yeah the earths going to flip over whats realy there to stop it from happening? thats like a reverce rotation have you ever watched water drain out of a sink depending on what part of the world your standing on is what way it drains outstop the flow you simp...

the evidence they ahve to show this is that deep on the ocean floor, the sedemnt very slowly moves, and as it does it becomes charged positive or negative based on the way the poles are oriented. they've found that ever few thousane years, as the sea floor is generated, the new parts show that it was charged one way for thousands of years, and then the other for thousands of years.

oh and also, they have shown the only thing that would happen because of the shift, is that the wind may blow differently changing some climate of some of the earth, and compases would point the other way. of these things nothing devastating would come logically. get a life all of you end of worlders
