Solar flare: The earth's atmosphere is much more stronger than anyone can predict. We have been hit by an x-rank flare, The strongest flares; and we're still living.
Planet-X: The guy who came up with it said he got abducted by aliens and the "aliens told him about Planet-X" AND The view of "Planet-X" could be Venus or Mercury behind the sun.
Mayan Calendar: This scientist that has studied the mayans basicly his whole life; Also an arcelogist (Can't spell) specificly says "The mayans may be as smart as us. But I have never read ANY of the mayans saying the world will end." The calendar ended because they could not predict anymore that will happen beyond that date. The only mayan living having the mayans as her ancestors also specificly said "No, (Insert mayan language here)"
Ect: The others are just bad theories for that one commercial or other programs to get more money. Others could be for the economy. They just wanna scare us off and make us waste our time like that uberly ridiculous Y2K theory.
PROBLEM UBERLY SOLVED.
