It is a fact that the Mayan Calendar will end on 12.21.2012. But, don't believe the hype... the world is not about to end.

Fox News Channel correspondents Adam Housley, Lauren Green and Amy Kellogg began investigating the Countdown to Doomsday last June on the Summer Solstice.

Debunking the Doomsday scenarios are astronomer Anthony Aveni, physicist Michio Kaku, archaeologist Christopher Powell and author Graham Hancock. Psychiatrist Dr. Keith Ablow delves into why the idea of a Doomsday is appealing to some people.

Mankind has long been fascinated with Doomsday and hundreds of thousands of predictions have been made about the end of our world. So what should we make of them?

Don't miss Countdown to Doomsday, hosted by Bill Hemmer, Wednesday at 9p ET on Fox News Channel!
