On December the 21st, the Earth will enter a ring called The Photonic Belt, at 1:00 am, when there will be a blackout on the planet and three days of darkness. NASA confirmed it on December 8th, 2012. They say that when it gets completely dark, it will be really cold and flashes of light will occur. Nothing will happen, it's just an extraordinary phenomenon that happens every 11,000 years.
It is recommended to stay at home, since there won't be any power and so electronic devices won't work. The three days of darkness will pass and that's what the Mayan calendar was referring to.
IF YOU PUT THIS ON YOUR WALL YOU WILL BE SAVED AND HAVE ELECTRICITY FOR 3 DAYS, INFINITE WHISKEY, 3 UNICORNS FOR PROTECTION, AN ARMY OF MAGICAL ELVES TO COMBAT THE ZOMBIE APOCALYPSE, AN ANGEL WITH THE FORCE OF THE UNIVERSE AND THE HELP OF SONGOKU'S GENKI DAMA TO EXPEL THE DEMONS. FURTHERMORE, YOU'LL APPLY FOR A RAFFLE TICKET TO WIN SAGITTARIUS GOLDEN ARMOR AND A ONE WAY TICKET TO NARNIA!
