I've been thinking a bit about that something might happen in 2012 and it might have to do with digimon. If it really does have to do with digimon, what if we're the cause of it?

We are trying to get to the digital world, which might leave a permanent hole in the path between dimensions. There are probably a lot of evil digimon in the digital world,who would to destroy us. Even if they're mostly idiotic digimon who just use brute force, it would take only one intelligent digimon to be able to find it, and they could bring the other evil digimon here. They might decide, "Hey, instead of destroying humanity, what if we enslave them?"

Humans might put up with it until the year 2012, when they would start to fight back. This could result in a war that would destroy humanity and the planet earth in a fiery hellstorm of death of destruction, and we would have caused it, by opening that first portal.. But thats the worst case scenario, and just a theory.
