VIDEO: The Hollow Earth, 2012, and much more by Dr Brooks Agnew
Several years ago I first heard about the "Hollow Earth Theory" from Rodney Cluff (OurHollowEarth.com). He is a mormon who believes some part of the Lost Ten Tribes currently dwell in the interior of the earth. The presentation and the evidence was very lacking and I was much more skeptical then than I am now (although I still have much skepticism)... but when I found out the main expedition leader (Steve Currey) died from brain tumors back in 2007, forcing the cancellation of the trip, I thought "hmmmmm, something stinks". Then I stumbled upon a rather hilarious and semi-recent interview of Rodney Cluff (here) where I found out that Dr. Brooks Agnew, a well known physicist and explorer, had also gotten on the Hollow Earth bandwagon and is actually planning a voyage for August of this year (see APEX).
I was first exposed to Dr. Agnew when watching the documentary "Bracing for Tomorrow". He may be wrong on some or many things, but this man is not some ignorant flake with just a "hunch". He has undeniable intellect and a profound gift of explaining complex science in such a way that even the unsophisticated can understand.
In the following two videos, Dr. Agnew describes the evidence for the Hollow Earth theory while being interviewed on Coast-to-Coast AM.
