Nasa debunks 2012 doomsday theory for a third time
New video pours scorn on doomsday scenarios - but doth Nasa protest too much?
NASA has once again debunked the myth that the world will end on 21 December 2012 – the third time since 2009 that the US space agency has felt moved to dignify 12-21-12 doomsayers with a response.
The current armageddon theory – the first major one since the Millennium Bug turned out to be a damp squib - has its origins in the widely held belief that the Mayan calendar comes to an end this December.
Now Nasa's Jet Propulsion Laboratory has produced a video in which Don Yeomans, a scientist with the Near Earth Object Program, patiently explains why each of the various doomsday scenarios proposed for 21 December will not happen.
No, there isn't a mysterious planet called Niburu on a collision course with the Earth, nor is there an international conspiracy of silence by astronomers to conceal its existence.
No, we are not going to be destroyed by a solar storm – besides, the so-called 'solar maximum' is scheduled for May 2013.
Yeomans goes on to pour good-natured scorn on theories to do with catastrophic tides caused by planetary alignments, the Earth shifting on its axis and magnetic pole rotations.
Whether you choose to believe Yeomans is up to you – but some might say, after this third intervention, that Nasa doth protest too much.
