In a new video posted online last week, NASA scientists from the Jet Propulsion Laboratory have addressed and debunked many of the claims of a doomsday scenario at the end of this year on December 21, 2012.
In the video, Dan Yeomans, head of the Near-Earth Objects Program Office at the Jet Propulsion Laboratory explains that the Mayan calendar does not actually end on December 21, 2012 as many people believe, but in fact it is just like December 31st on our calendar, when the year ends and another calendar begins.

Yeomans also addressed the belief that another planet named Nibiru will collide with Earth in December, stating that if this were in fact to happen, scientists would have seen it long ago and if it were somehow invisible, they would also notice the gravitational effects of this planet on other nearby planets.
Some also believe that some sort of planetary alignment will cause catastropic tidal effects on Earth in December, but in response to that claim, Yeomans says that there are no planetary alignments scheduled in December, and even if there were, there would be no tidal effects on Earth as a result.
As far as a shift in the axes of Earth, Yeomans says that is not possible because the orbit of the moon around our planet stabilizes it. A shift of the magnetic field does occur every 500,000 years or so, but there is no evidence of this happening and it would take thousands of years to do so if it were happening, which would only be a problem for compass recalibration on Earth and nothing more.
One final impact that many people believe will cause the doomsday scenario in 2012 is from solar flares. Yeomans explains that the sun goes through a normal 11-year cycle that actually peaks in 2013, but there are no health concerns over solar flares. They are potentially a problem for our communication devices and potentially the power grid, which in turn could create other problems.
So what do you think? Is NASA right and will December 21, 2012 be just another day, or do you think something is going to happen to end the world? And if so, what do you think will happen? Sound off below in the comments section…
