I would vote something in between, but since it doesn't exist, I didn't vote.
Before I say anything, I'd like to inform that none of the things below are of my own opinion, they're not necessarily true, and I don't necessarily believe them.
It is rumored that a number of events will take place in 2012 which might bring an end to this world:
1. The end of the Mayan Calendar will happen in December 21 2012. This gives a lot of people a belief that maybe the Mayans were pointing towards the end of the world, or a new age, or probably a change in world order.
2. 2012 is believed to be a year of spiritual transformation, when humanity might be elevated to a new level.
3. 2012 is believed to be the time for apocalypse's arrival according to some religious hints.
4. There are also theories that a currently unknown planet, sometimes referred to as Planet X or Nibiru, which supposedly has an odd orbit that only enters the local solar system every 3600 years will return in 2012 causing many problems.
5. Some scientists claim that an alignment will occur when the sun rises above the horizon on December 21 2012, at which point the sun will rise in the middle of the Milky Way Galaxy, thus causing an alignment between the earth, sun, and the galactic center.
6. There is supposed to be a huge solar flare in 2012, which will be very destructive.
7. A date predicted for the eruption of the Yellowstone Volcano, which might be great enough to send up a huge amount of smoke and ash, which will later cause the sun's rays being blocked and an Ice age to return, which will supposedly finish everyone.
8. Greenhouse Effect will become dramatically noticeable, and the melting of Greenland and the south pole might drown a huge part of the world.
9. There is a great possibility that in 2012 a shift of the Earth's magnetic poles may occur. This will leave the earth vulnerable to harmful radiations from the sun, and will cause all magnetic/electronic devices, or things that take help from them, to become haywire and eventually useless. This will bring down a huge part what we need to live.
10. Another possibility is that an actual physical shift in the Earth's magnetic poles may occur in 2012. Physical shift means the poles will actually move, and believed to happen at great speed. This movement, which actually has been researched to happen before, has been predicted to strike this 2012 with much greater force than ever before, enough to destroy all cities and maybe even open up huge fissures in the plates.
There are some more possibilities, I think. But I personally don't believe these much, and so am not sure if it is going to be the end of the world. It's all rumor after all.
But I do believe that there will be some great revolutionary changes in 2012, not necessarily destructive, but maybe good changes. I know it will bring a good change to my life :)
