- A massive comet/asteroid will crush Earth. (though it wouldn't be impossible, I find it hard to believe the Mayans would have exactly predicted it)
- The religious belief of Nibiru passing through our solar system & ripping Earth to shreds.
- Aliens will arrive on planet Earth, and allow us to get on board their Mother Ship while the Earth undergoes it's transformation.
- A great shift in spiritual consciousness..
The only theories that I can find myself really following, is a global blackout.. all power across the planet goes, and the humans of this planet go into a massive panic. Looting, killing, struggling for survival, etc.
The other is the Sun and Earth will align.. and the Earth will experience a tilt (but nothing apocalyptic will happen). The last theory, being the shifting of the poles which would clearly explain the very odd weather behavior we've been getting these past few years.
The Mayans never mentioned anything about the end of the world, but people are so quick to believe that it is what will happen.
fix'd.The Sun is gonna blow in another 5 billion years.
