• John Titor Times – Website about John Titor, the guy who claims to be a time traveler who returned from the year 2036 to talk to the Coast-to-Coast radio show and give us warnings about our times.
• The Moon - What Is It And Who Made It? – New research shows that our Moon is much older than originally thought. Earth is estimated to be 4.6 billion years old. However, Moon rocks were dated at 5.3 billion years old, and the dust upon which they rested was about one billion years older. Who put it there and why?
