Nasa scientists have no doubt the world will still be in one piece next week, beyond the Mayan-predicted demise on December 21.
They have already released a video, called 'The World Didn't End Yesterday', which pulls the prophecy to bits.
At the outset of the video, meant to be watched by viewers the day after the supposed end of the world, it says: "If you are watching this video, it means one thing. The world didn't end yesterday".
The video points to the theories of Dr John Carlson, the director of the Centre for Archeoastronomy.
He is backed up by Nasa scientists reported on the space agency's website."The world will not end in 2012," said a group of Nasa scientists.
"Our planet has been getting along just fine for more than 4 billion years, and credible scientists worldwide know of no threat associated with 2012."
They write the predictions started with the idea a planet called Nibiru was headed toward Earth.
"This catastrophe was initially predicted for May 2003, but when nothing happened the doomsday date was moved forward to December 2012 and linked to the end of one of the cycles in the ancient Mayan calendar at the winter solstice in 2012 - hence the predicted doomsday date of December 21, 2012."
They conclude by asking "where is the science?" of the claims, and say there is no credible evidence for any of the assertions made about weird events happening in December 2012.
