I have listed all the possible 2012 predictions with a brief description of what may occur for 2012 year. The 2012 predictions:
1.Nostradamus – While Nostradamus is very vague, he has predicted the end of the world through his past prophecy and drawings to be around the year 2000. The exact date is never given, but he indicates that the world will end through nuclear warfare or some other possible cause, by the means of “the heavens will catch on fire.” Some believe he is the most important prophet for the 2012 predictions
2.Web Bot- A computer program used to search through data and pull together important data that can predict future events. It was built for investors and since then has a built a remarkable record for the prediction of the future events.
3.The Bible – The Bible predicts that the world will come to an end when the Antichrist rises. Some believe the Antichrist is already among us and the countdown to the end of world has already begun. The Bible has been useful in the past and thus provides to be a possible reliable evidence.
4.The Antichrist – Nostradamus and the Bible predict the end of the world to occur when the Antichrist rises. There is great speculation around Obama being the Antichrist. The speculations hold that when his presidential term is just about done the world will come to an end, as mentioned in the Bible, “the 42 months of power and then....”
5.Mayans - Maya Calendar ends on 12/21/2012, symbolizing the end of a cycle and into a new one as earth enters the “cosmic womb.” Some believe that a transformation through other forms of life in our solar system will come to earth or earth will completely perish.
6.Polar Shift – Polar shift can cause increased weather patterns and potentially catastrophic climate change. The polar shift wouldn't cause earth itself to end, but rather an increased amount of damage dealt upon earth via earthquakes, hurricanes, volcanoes and so on.
7.Planet X – A new planet in our solar system that is suppose to collide with earth in 2012. The orbital pattern of the planet comes within very close proximity of earth and provides relatively strong evidence for the collision of earth. Though this evidence may seem conclusive, other calculations have been made to show that it will pass by earth.
8.Comets – Comets from Planet X as it approaches earth can enter earth's atmosphere and either reach earth or disintegrate upon entering the atmosphere.
9.Meteor – A large meteor can collide with earth causing everything on earth to become extinct. This is a very similar scenario to the extinction of Dinosaurs.
10.Nuclear Warfare – Everything will end through war and the destruction of atomic bombs. This theory is highly unlikely saying as someone needs to be alive to launch the last bomb thus proving at least some civilization will live.
11.The Alignment – Potentially earth can be lost in a black hole during the winter solstice in 2012. Since earth will be at the center of the Milky Way, where a black hole is located, some astrologers believe we will become lost within it. No one knows the actual outcome of this and it just seems to be another proposed theory of a 2012 predictions.
12.The I Ching – An ancient text used to predict random events. It was calculated out into a timeline and when doing so it mysteriously ends on the year 2012. Since it is based on sequence of events people are suspicious about how it could just end on that date.
13.Solar Storms – NASA has now confirmed that in the year 2012, the sun would have reached its peak of solar storms. It will be unlike anything earth has experienced.
14.Tibetan Monks – With the use of Remote Viewing, the monks are able to predict the future. The Tibetan Monks have declared doomsday to be in the year 2012 through nuclear warfare. They also declared that we will be saved by extraterrestrial life.
15.Depression – Some economists believe that a depression is to occur in 2012. This is unlikely saying that we should be recovering from this recession by then but yet again, we could go into one through nuclear warfare.
