2012 is different then the past "end of the worlds"
Y2k was never the end of the world.. it was feared because computers to that point only used 96,97,98,99 and they feared when everything reset to 00 systems all around the world would crash and there would be mass chaos.. they fixed all the major cases way ahead of time and obviously nothing happend..
many different cultures all around the world predict 2012 having a significant meaning to us as humans, from what the mayans say "Human life as we know it, will cease to exist." this does not mean earth is going to blow up or all humans will die. but SOMETHING drastic will occur that will change life as we know it..
possible new discovory that changes all science?
nuclear war?
the rapture?
meteor?
solar flares?
regardless of what you want to believe or not, i personally think that something will happen in 2012. im not going to quit my day job over it or anything, but im still thinking everyones life will be affected somehow. might be small, might be big idk
