So, dismissing out of hand any claims of prognostication (given that those claims don’t tend to pan out), what is the probability that the world will end in 2012? But with the end of the world, we know it’s certainly possible. We know that the Earth has endured environmental catastrophes that any human survivor (if there were survivors) would call “the end of the world”. So, could the world end any day now? It’s kinda comforting to think that the ancient Romans, Mayans, Norse, Indians, freaking everybody, had people running around predicting the end of the world.
