The End of the World has been speculated almost every year by some group of humanity. This means many different things to many different people. For a while, people believed that December 21st, 2012 was the end of the world because the Mayan calendar ended on that date. But, in Summer of 2012, more calendars were found, proving that the date is not the end of the world. The popular speculation these days is that of a zombie apocalypse.
