Here's something no one actually thought of was to happen...
I'm setting aside religious bias (I am not christian, baptist, catholic, hindu, or whatever..) aside, what about the possibility of another planet or something coming close to earth?
IMO, I believe that is the more likely case. I found some stuff about a so-called planet called "Nibiru" (it has other names, but I call it 'Death Star') that has been pretty much hidden from the general public by NASA. Honestly, I know there has to be some other sort of celestial body going out there. Nibiru is said to be about 4-8 times the size of Earth, so pretty much bigger than Jupiter. I don't know it's current location though, and it also mentioned that Antarctica is the only place to actually see this planet right now.
Nibiru is supposedly a dead or failed star, since it has been noted as a Brown Dwarf, so.. things could get messy. Planet X Facts
was one site I read this stuff on. Nibiru
was also mentioned on this site as well.
I'm still highly skeptical right now, but if this.... planet/star truly is real, it really could wipe out the better part of the population of Earth. I'm not saying it's the end of the world, I would just.. kinda say it's more like the end of current humanity as we see it.
I think that about ends my take on the matter... 2012 is highly debatable at the moment, and the gov. does like to cover things up fairly well.
