Like what the title says, everything will be destroyed on February 22, 2014. The sun will be destroyed and the moon with the stars erased, the soil and the sky will be doused with poison and the water levels will rise and drown all.
That is if you are a firm believer of Norse mythology as experts have determined that date as the start of "Ragnarok" or the final battle wherein the Norse gods will all be killed trying to fight evil. It all leads to Odin's death and the Earth will be submerged in the sea and will rise as a new world that is flowing with limitless food and supplies.
So yeah, say goodbye to your loved ones as the final battle is imminent. Sell your stuff, resign from work, hug your dog, and hone your swordfighting skills.
