what happens in 2012? would the world end?

Long Count Calendar of the Ancient Mayans ends on Dec 21 2012.
On December 21st, 2012 there is a close conjunction of the Winter Solstice Sun with the crossing point of the Galactic Equator (Equator of the Milky Way) and the Ecliptic (path of the Sun).

There isnt much info on what Mayans thought would happen in 2012, but the consensus of opinion is that there will be great change. To some people this means a positive, spiritual change. Others consider that a catastrophic event may have been predicted.

Is the world to End?........
