If there are any worriers out there.... nothing will happen. For example-Nibiru will not collide with Earth. We would see a big a$$ planet headed at us in only 4 days. Big ole asteroid would also be seen and noted by scientists if only 4 days away. Nuclear war- no reason at this point in time for such a thing to happen. Zombies- disease would not spread in 4 days and probably already noted. Huge earthquake-plausible, but the probability of one exactly in exactly 4 days is next to none. So have now worries. Aside from that, the Myans didn't account for leap years, so the world should of already ended :). The sun won't explode or die either as it is only on it's half life and still would take another half a million years for us to notice to due light years... If anyone has anyone to fix or add, feel free to do so. Or just post your thoughts on it.
