Almost everyone, with the emphasis on almost, no longer believes in a flat Earth, therefore why is it that some still believe today in a hollow Earth?
It almost seems impossible, or extremely unlikely, that with modern day scientific advances, a rational person would suggest he or she traveled into openings at the poles that allowed them to see amazing things. Some believe that the famous United States Admiral Richard E. Byrd was one of those supposedly rational persons that claimed to have visited such an area.
Supposedly, different factions of United States media reported on Admiral Byrd’s forays into the unknown openings into Earth, but those reports were quickly squelched.
Another person with an intense interest in openings to the inside of Earth is the evil Adolph Hitler. Legend or rumor has it that Hitler, and some of his high ranking associates, escaped to an opening at the South Pole, rather than having committed suicide as has been widely reported.
No matter what one believes, the idea of a hollow Earth is very interesting and intriguing, and it is the subject of many science fiction publications and productions. Apparently, there will always be some who believe in the possibility of what seems impossible to most of us.
