Yes. A magnetosphere is generated by an iron core. Without one, solar radiation would have ripped out atmosphere like dust billions of years ago; before life ever had a chance. It also gave us an understanding of MRI machines, which have saved countless lives.
literally impacts our survival, so before you speak think about Normandy beach before it was beseeched; what would have happened to the world? Would we have this plethora of girls? Girls eventually turning in to women; it's akin to the skin that's giving you the win. Wind..... earth, fire, ice, look into my eyes and then think twice before you lie... to yourself, might want some help but i'm a mighty guy who can help you with the mechanics of how to survive.
Yuck.
Cool otherwise though.
What the deal with the magnetosphere thing? Is that special?
