This is a switching subject - not bait and switch, but:<br /><br />Is earth's magnetic field about to switch, or switch off before switching?<br /><br />As a tangent from my surviving red giant phase thread: can we strengthen earth's magnetic field so as to give protection from the solar corona at red giant phase?<br /><br />I know this is hard - like science fiction - but technology has been advancing rapidly and we have billions of years.<br /><br />How is earth's magnetic field propagated and why does it switch?<br /><br />If we, over billions of years, construct multiple levels of existence deep within the earth, can we effect earth's magnetic field?<br /><br />My inspiration for this question comes from a classic Science Fiction movie: Forbidden planet.<br /><br />On planet Altaire 7 (Science Fiction) the advance civilization known as the Krell (sp?) constructed multiple levels all the way to the core of the planet and harnessed the planets energy. The huge planet sized structure was maintained by self-repairing robots.<br /><br />Science fiction can become fact.<br /><br />Can this be done by us in the upcoming billions of years?
