Some theories say that the aligning of the planets and the sun etc... will cause strange photomagnetic waves to be released and cause a change in the brain chemistry/composition and we will "awaken" so the big change in 2012 is actually going to be a movement into a higher spiritual plane or something like that. That's what I believe, or maybe I'm just trying to be as optimistic as possible.
However if we have a specific date/time that it will happen I plan to take a bunch of acid and skydive with no parachute while having mid air sex and watching the Earth implode. It will be so tight.
Yeah I don't think anything is gonna happen, but if I had to pick one or the other I go along the lines of the advancement/enlightenment of society type thing. If there is mass extinction, oh well, we go into the next dimension, there have been mass extinctions before, who cares, but I don't think that is gonna happen, we would be a pretty stupid race if we didn't know some shit like that was coming, if we couldn't predict 50 years ago that the world would end on Dec 12, 2012, then we are pretty fucking regular. So don't worry nothing violent should happen, unless humans cause it, imo.
But yo its super funny theres this thread because there is a shit load going on with UFO sightings right now.
