There are many predictions surrounding 2012, here is a list of the most prominent ones.
Mayan Calendar
Propaganda
The end of the Mayan calender stops on December 2012. The exact date is under speculation but they are generally accepted as either the 12 or 21. Some believe that the stop of the Mayan calender is the sign that the end of the world is near.
Planet X or Nibiru
Planet X or Nibiru is actually a brown dwarf star half the size of the sun that is suppose to crash into the world December 2012. In response to this, people are moving into underground bunkers and stocking them with supplies well past a year.
Solar Flares
The increase of solar flares has been reported and on the rise in the past few years. Under this theory, when December 2012 arrives one of the largest solar flares we will have encountered will hit planet earth. This will cause a shift in the earths axis and cause natural disasters ranging from tsunamis, earthquakes, volcanic activity, nuclear meltdowns, floods, fire and death.
In response to this, people are moving to places of high altitude away from nuclear plants, volcanoes and fault lines. In the USA alone, there are 3 super volcanoes - in Wyoming, New Mexico and California. Other supposedly dangerous places include Europe, parts of Canada, South America, Asia and Australia.
