I once had a chat with one of my collegues. We discussed our previous jobs, and he told me about his former appointment at a University, where he did a geological survey. In this survey he (again, because there had been others) found evidence that the magnetical field flipped over at least once.
The question is: What will happen to Earth and its inhabitants? When the magnetical field "collapses", or rotates, there could be one point where it doesn't protect us against the radiation found in space. But this radiation is lethal to any living being. Well, at least it could increase the "speed of evolution" by rapid mutation.

During the past several days I have investigated this topic as well as a few others. At first they seemed to have no linkage to eachother except the fact that they were things that were unxeplainable, mysterious, etc. But then I realized that they are infact all related, to the date 2012. That fateful day seems to be the end of all of these things i have investigated. Amongsted the things I have investigated inclue: Time travel, polar switch and the Mayan calender. Time travel is related to this in the fact that the people who have claimed to 'time travel' have not been able to pass the year 2012 and are only able to go around it, in witch they find a statue of a golden horse and no civilization. There are a few things that point towards how 2012 is going to change. They where not able to go beyond 2012 becuase we will be changed for better or for worse and our 'future life' does not exist at the present moment. If someone where to be able to pass the year 2012 than they would know everything, and that can simply not be allowed so a wall was set up to prevent such interaction. The golden statue probably simbolizes a new 'golden age' if i may be entitled to say so. I am aware that time travel is a sticky buisness and is yet to be completely proved but I still belive it can be used to test the year 2012. As well i belive that the polar switch will take place in 2012 causeing utter chaos or at least change us greatly. And as you know the Mayan calander suggests December 21st, 2012 to be a significant day or the 'end day'.
I would also like to add the alignment of a few galaxies as well as the transit of venus that will take place during the year 2012. Take into consideration that I am only 13 and do not have much knowledge on this, but I still belive that all these are related topics. Please tell me if you think im insane : )
