We can blame it all on the Mayans. They created the Long Count Calendar, a time measurement system that had spiritual significance to their culture. They organized their calendar into several cycles, the last of which will end in December 2012. Some people think the Mayans had discovered that after 2012, the world would end.
There are dozens of theories about how this might happen. Some claim that 2012 is when the Earth will experience a polar shift (see above). Others say that after 2012, the Earth will experience a period of terrible destruction followed by a new age of peace and enlightenment. A few claim that in 2012, a secret government will accomplish its goal of total world domination. What will actually happen? Check back with us on Jan. 1, 2013.
