I have learnd that our Magnetic pull is fading away. As we know, The sun sets off a "big blow off" as I like to call it, that creates solar wind and it blast through the solar system. Well Earth is directly in that path! As we know it, our magnetic feild, created by the core, protects us from this wind. We can see this transition occur over out head. How? It's something called "The Northern Lights" .
Hahaha, its funny how I know this~
