Hollow Earth Theory has fallen into back recesses of the mind save for a few. Dr Brooks Agnew attempted to organize a Hollow Earth Expedition back in 2007, when the previous organizer passed away. The expedition has failed to materialize to date. Rodney M. Cluff, author of ebook, “World Top Secret: Our Earth Is Hollow,“ fascinated in theory since his teens, is also part of expedition. Dean Dominic De Lucia has written book, “Hollow Earth In The Puranas,” and recently interviewed on Red Ice Creations Radio. Hollow Earth Theory refuses to go away, completely. Above video is amazing and updates a theory hundreds of years old.
