Mayan calendar runs out in December, which coincides with the 11 year cycle of Solar maximum. Super-EMP in the form of a solar flare wipes out all technology. Anarchy, starvation, no more internet prawn. Mass hysteria. Dogs and cats living together. Mel Gibson wears football pads and saves... um... the highway from... um... that guy from the Cure and his shiny silver boyfriend.
I'm sure we'll pull through thoroughly, though. Thoughts?
Sunspot numbers are a pretty good indicator of solar activity; and although the solar maximum will occur in late 2012-early 2013, it's likely to be a relatively low maximum. Having looked at weather data for the last hundered years, I've noticed that extremes in temperature and weather tend to correlate with solar minima...
...so according to this, the world should have ended in the late 1600's. It would have been the perfect time too what with outbreaks of plagues, religious persecution, and widespread violence and warfare. The world is only going to get more peaceful, so if Jesus H. Christ is going to come back and usher in a new era of peace in a fallen world, he'd better hurry up. We humans may figure it out soon without divine intervention.
