The talk about the doomsday has recently made one to recall the Mayan inscriptions and 2012 alignment of planets. The whole universe is said to be emerged out of the single big mass. Based on the way it spread out it got organized and turned out into various planets. The much discussed 2012 doomsday believes deals with various catastrophes that are profound to occur. There are pertinent facts which a believer possesses to the rationalist about the Mayan inscriptions and the end of world.
What is a planetary alignment?

The Mayans have believed in 2012 alignment of planets. The Mayan calendar seeks this as the prime cause which may lead to the end of the world. Planets have always been looked as scared by people of many civilizations which guide them to the good and the evil. Even today in this modern era people believe in planets motions to bring good fortune. Actually an alignment of planets may be considered in two different manners. One particular way is that considering the view from sun and seeking the planets to be arranged in a straight row. Another way to predict the alignment is that to imagine a straight line which passes through exact center of all the planets. Many astronomers and scientist have said that this particular pattern is very difficult to occur since each and every planet has its own alignment in the solar system. So the probability for all the planets to align in a straight line would be very low or impossible. Thus this fact proves out that the world might not have an exit in 2012.
Invasion by aliens:
The Mayans have made out the calendars according to the alignment of the planets and thus benefitting them for administrative as well as agricultural use. Beyond this planets were looked worshipped. The long term calendar which has been inscribed by the Mayans long before is about be end by December 21st 2012, which mark of the solstice. It put forth the theoretical calculation and thus evidencing the end of world by 2012 alignment of planets. It is the belief by the Mayans that by the end of long term Mayan calendar the earth would be collapsed with black hole or with some other planet. Most of the scholars who have the deep insight knowledge of these Mayan civilizations say that the collapse would not be the true prediction that was left out by the Mayan astronomers. But it might be the phase of transformation from one form to another. Some also say that it might be the shift of the power from the human beings to the aliens. Some still belief that some part of the universe may have aliens in them who may take over the earth by the end of 2012. An ancient drawing obtained from the Mayan civilization depicts a scene describing the transformation of power from the men to women. This has made many to study deep about the prediction of the Mayans.
