The Hollow earth theory

Umberto Eco writes for The Guardian on “on why we should beware mad scientists” :


“…Symmes believed that at the north and south poles there were two apertures that led to the interior of the globe. He attempted to raise funds for an exploration of the polar regions to locate these entrances. The Philadelphia Academy of Natural Sciences still has a wooden model he used to explain his theories…

…It is widely rumoured on the internet that the hollow earth theory was taken seriously by top-ranking Nazis who believed in the occult sciences. In some circles of the German navy it was purportedly believed that the hollow earth theory would make it easier to pinpoint the exact position of British ships because, if infrared rays were used, the curvature of the Earth would not have obscured observation.”
