There are many different theories about the 2012 "end of the world".
1)
The Mayans never said it will be the end of the world.
It's just the end of the actual era (the 5th one from the Mayan calendar).
Their eras are called "sun".
They believed there were 5 big time cycles (or 5 suns). after the 5th one ends, we will go back to the 1st sun. (Even if I found "Mayans seventh sun cycle" on a website)
The suns are divided by 4000 years each (more or less).
Since humanity exists, there were 4 end cycles, so we are now in the 5th cycle "since the beginning of humanity", not since the beginning of the world.
I found a french site, I translate it a little here :

QUOTE said:
" The first sun, Matlactli Atl : 4 008 years. At this time giants lived. The first sun was destroy by water.
all Humans transformed into fish but one couple who gave birth to humanity again.
" The second sun, Ehecoatl : 4 010 years. This sun was destroy by Ehecoatl (The wind snake) and humans were changed in monkeys.
A man and a woman was saved from destruction"
" The third sun, Tleyquiyahuillo : 4 081 years. This sun was destroy by fire. Humans descendant from the second sun's survivor couple, ate a fruit named tzincoacoc ..."
" The fourth sun, Tzontlilic : 5 026 years. Humans died of hungry after a fire and blood disaster."
I never found what the Tzincoacoc fruit was, nor what was its effect
Googling it only shows many site with the text above.

- Next, there's this astral plan crossing with our Milky way, each 33 million years.

The earth magnetic pole are changing every 250 000 years (medium value, sometime very short, sometime almost 1 million years), but the last one occurred 750 000 years ago.
it may be time to change. But I don't know the process speed. it may take hundreds of years.

And finally, anyone watched anime's Lain ?
It speak about the Schumann Resonance.
http://en.wikipedia.org/wiki/Schumann_resonances
See the french one for pictures :
http://fr.wikipedia.org/wiki/R%C3%A9sonances_de_Schumann
It's the earth frequencies changing gradually, to finally be in resonance with the human's frequencies (8hz) in 2012.
Lain anime was based on this frequencies to receive/transmit data from brain to brain without a wired connection (a wifi like internet).
Again, the Earth don't have only 1 Schumann frequencies, and nothing is happening to us.
The main frequencies is at 7.83 Hz (in 2004), and is growing slowly.
It's said that it will affect our brain when this frequencies will be from 8 to 11 Hz (the one from the Alpha frequencies the brain emit when we are in paradoxal sleep state)
Could it explain why a lot of people have ESP power like seeing ghost, telepathy, etc? They are often categorized as Schizophrenic because they hear voices or see things the doctor don't.

Thanks to Smartpal (next post), I forgot this one
It's the end of the Kali yuga.
The Indian/Hinduism era, which is 2 400 years long each.
(I need more reading to understand it, there seems to be 2 Kali Yuga timing)
6)
based on the earth's axe orientation on the celestial map. We are exiting the fish zone to enter into the virgo one.
It's meant to be a pure water era. (I don't think our water is really pure with all those pollution the humans are doing)
