What do you guys know regarding the hollow earth theory? Some fairly compelling evidence related to eyewitness and written accounts such as Admiral Byrd and Scandavians from hundreds of years earlier who claimed to have been there. Also the Nazi's believed it to be true and there is significant evidence that they may have went there as well. Recently official Nazi documents and Nazi maps have surfaced on how to enter the hollow earth, via tunnels at the bottom of the ocean into a civilization known as "Argatha". Recently Uboat instructions have surfaced on how to navigate the tunnel system. Pretty interesting..
