2012: Interstellar Endings

There have been a lot of articles in some of the news feeds that I frequent discussing how ludicrous an idea it is that the world will end in 2012.  NASA has already debunked most of the theories regarding the role objects in space will play in our hypothesised short-lived existence.  Despite what some people would like you to believe, a giant asteroid is not going to crack the earth in two, a solar storm will not "crisp" us,  and a mysterious planet X or brown dwarf named Nibiru or Eris is not going to play interstellar bumper cars with us.  At least not any time soon.  Many of these theories are plausible and scientifically grounded:  giant objects have peppered the Earth in the past, we were recently showered with a massive solar flare (few people noticed), and Earth has supposedly been struck by a large planetary object which is one hypothesis as to how the moon formed.  That being said, with all of the technology we find ourselves in possession of these days, we can accurately predict where, when and if any of these events will actually befall Earth.  For the first time in history, Earth actually has an early warning system for interstellar catastrophes.  So far the radar looks clear for 2012, 2013, 2014 and beyond.  Of course all this doesn't rule out the possibility of something Earth-based going completely awry.  Theories include a super volcano located under what is now Yellowstone National Park exploding, lethal pandemics like the bird flu, a world-wide food shortage, and a nuclear Armageddon brought on by our own devices. In regards to the latter, I dug up one brilliant movie from my adolescence that describes how these weapons could end it all.  I honestly think it is one of the most plausible scenarios for the apocalypse.  Enjoy.
