People obsessed with "End Times" prophesies claim that there is a huge planet Nibiru (sometimes called Planet X) on its way, ready to collide with earth and destroy life as we know it. There is no scientific evidence for such a planet.
Scientists also point out that the Mayan Calendar does not end in 2012.
Another doomsday proclamation has to do with solar flares, but science has proven that these are cyclical.
There is no evidence whatsoever that the 2012 doomsday prophesies have any validity.

A Scientific Reality Check: There apparently is a great deal of interest in celestial bodies, and their locations and trajectories at the end of the calendar year 2012. Now, I for one love a good book or movie as much as the next guy. But the stuff flying around through cyberspace, TV and the movies is not based on science. There is even a fake NASA news release out there… So here is the scientific reality on the celestial happenings in the year 2012.
