December 2012 Doomsday is actually not coming ...

There was lot of talks about impending doomsday in December 2012. The Hollywood and many of the the media rallied around the point and aired the Doomsday often pointing to the Mayan Calender which according to them has ended on December indicating the end of the world. But the scientific community has nevertheless rebuffed the doomsday allegation and has logically explained the reasons.

• The story started with claims that Nibiru, a supposed planet discovered by the Sumerians, is headed toward Earth. This catastrophe was initially predicted for May 2003, but when nothing happened the doomsday date was moved forward to December 2012. Then these two fables were 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.

  The Mayan calendar does not cease to exist on December 21, 2012. This date is the end of the Mayan long-count period and another long-count period begins for the Mayan calendar.
• 
  There are no planetary alignments in the next few decades, Earth will not cross the galactic plane in 2012, and even if these alignments were to occur, their effects on the Earth would be negligible. Each December the Earth and sun align with the approximate centre of the Milky Way Galaxy but that is an annual event of no consequence.
• 
  Nibiru and other stories about wayward planets are an Internet hoax. There is no factual basis for these claims. If Nibiru or Planet X were real and headed for an encounter with the Earth in 2012, astronomers would have been tracking it for at least the past decade, and it would be visible by now to the naked eye.
• 
  A reversal in the rotation of Earth is impossible. There are slow movements of the continents (for example Antarctica was near the equator hundreds of millions of years ago), but that is irrelevant to claims of reversal of the rotational poles. However, many of the disaster websites pull a bait-and-shift to fool people. They claim a relationship between the rotation and the magnetic polarity of Earth, which does change irregularly, with a magnetic reversal taking place every 400,000 years on average. As far as we know, such a magnetic reversal doesn’t cause any harm to life on Earth. A magnetic reversal is very unlikely to happen in the next few millennia, anyway.
