   Was Noah's Flood a symbol for real people who were driven from a real homeland by a real flood? In an extraordinary geological detective story, two of the world's greatest earth scientists travel to the Black Sea to reveal evidence of a mighty torrent that poured through the Bosphorus with the power of over four hundred Niagara Falls. Did this catastrophic event, only 7,500 years ago, become the stuff of ancient storytelling and the origin of the Biblical Flood?

3. The Bermuda Triangle
   
   The Bermuda Triangle, also known as the Devil's Triangle, is a region of the northwestern Atlantic Ocean in which a number of aircraft and surface vessels have disappeared. Some people have claimed that these disappearances fall beyond the boundaries of human error or acts of nature. Some of these disappearances have been attributed to the paranormal, a suspension of the laws of physics, or activity by extraterrestrial beings by popular culture. Though a substantial documentation exists showing numerous incidents to have been inaccurately reported or embellished by later authors, and numerous official agencies have gone on record as stating the number and nature of disappearances to be similar to any other area of ocean, many have remained unexplained despite considerable investigation.
