Nasa has released a video ahead of schedule tackling the 'myths' surrounding the belief the world will end on December 21st.
The video, which was clearly intended for release the day after the 21st, begins: "December 22, 2012. If you're watching this video, it means one thing. The world didn't end yesterday."
It goes on to attempt to debunk the ideas surrounding the so-called 'Mayan prophecies', saying the date is based on a misconception.
Making the argument point by point the video sets to put to rest the catastrophic prophecies, including debunking the notion that the sun will irradiate the atmosphere or that another planet will smash into Earth.
