Think Tank _ Hollow Earth and What Lives Within _ The Confessionals

In Episode 132: Hollow Earth and What Lives Within, we “dive in” to hollow Earth with another edition of the Think Tank! Is a hollow Earth really possible? If so, why is it there? Who lives inside of it? What is it being used for? These thought-provoking questions and many more will be covered as Justen Faull, Wes Faull, Chad Riley, and Jim Wilhelmsen join The Confessionals to discuss the mysterious hollow earth.
