An explorer has bought a Russian icebreaker and is heading out to the North Pole to determine if the Earth is hollow. Here's the pitch from Steve Currey's Expedition Company - Voyage to Our Hollow Earth: "Don't miss this chance to personally visit that paradise within our earth via the North Polar Opening and meet the highly advanced, friendly people who live there. We are of the opinion that they are the lengendary Lost Tribes of Israel who migrated into the North Country over 2,500 years ago and literally became lost to the knowledge of mankind. "
