I don't think so. It was a simple expression by the Mayan Calender to signify the end of a temporary period. I doubt they said anything about the World ending and, you know, Television loves screwing with the truth to make it seem terrifying.
actually I think that something big is going to happen between Dec 21 and Dec 23. I know people keeps comparing this to the 2000 millennium thing. but back then it was just a religious based thing... now its different. We have a Planetary alignment, End and Maximum of the Solar cycle and the weakening of the magnetic field plus I Hate when people say that Mayans just ran out of calendar. When they stated clearly the world had ended 4 times before by fire, ice, water and earthquake (just like ancient Egyptians and Chinese) and that we are at the edge of the 5th . .And we shouldn't make fun of a entire culture the Invented the Most exact calendar of all and had more Astronomic knowledge than our current scientists, plus the knew about the black hole in our galaxy and predicted solar and lunar eclipses thousands of years before they happened... and those predictions were very much accurate. I'm Not saying the world Itself its going to end but something Big may happens
