Do you mean something happening like the total collapse of the worldwide economic market? Do you mean riots and rebellion because all the politicians can think to do is declare martial law, install curfews and punish their citizens for the problems they, themselves have caused? Do you mean urban centers becoming nothing more then battlegrounds, fire pits and chaos because people can't feed themselves and can't depend on the government to do a damn thing but screw shit up? Do you mean sickness and death because people just don't give a shit about their neighbor? Do you mean murder and rape because chaos will rule? If this is what you're talking about then I don't know, could it happen? Is this what you want to happen?
No. Nothing is going to happen on 12/12/2012....for those who don't have all the info, this date has become famous basically because the formidably accurate Mayan calendar stops on this date, and the Mayans interperated this date as the day upon which a massive astrological event will happen.
Our popular media has turned the traditional Mayan belief into the end of the word and/or total apocalypse. It gets ratings and The History Channel can run special after special about it. But as far as I'm concerned, this massive outer space thing is not going to end the world, we are not going to have anything like the Maximum Overdrive comet tail that animates lifeless objects, nada. Its just a fluke.
Nothing will happen. In fact, the Mayan calendrical reference to what is our 2012 is obscure and only appears in one fragment, out of hundreds from the remains of classical Maya civilization. The idea that the Mayans thought of what we call 2012 as a "world shift" or some apocalypse is simply post-1960s granola from the "New Age."
