While Dec. 21, 2012 is commonly referred to as the Mayan apocalypse or the end of the world, NASA has released a video explaining why the rumor is all on big hoax.

The video, which was apparently supposed to be released on Dec. 22, is titled "The World Didn't End Yesterday" and explains how the idea of the Mayan apocalypse was a huge hoax and how the rumors began.

The four minute clip has been making its round on YouTube and has been appropriately nicknamed by users, the “Told Ya So” video.

According to a Time magazine report, the space agency has been bombarded with questions as to the validity of the Mayan apocalypse theory. As a result, NASA has devoted a section of the website to debunking the claims.

"The world will not end in 2012," NASA writes. "Our planet has been getting along just fine for more than 4 billion years, and credible scientists worldwide know of no threat associated with 2012."

NASA experts go on to explain the origins of the hoax. "The story started with claims that Nibiru, a supposed planet discovered by the Sumerians, is headed toward Earth. This catastrophe was initially predicted for May 2003, but when nothing happened the doomsday date was moved forward to December 2012 and linked to the end of one of the cycles in the ancient Mayan calendar at the winter solstice in 2012—hence the predicted doomsday date of Dec. 21, 2012."

In addition, NASA denies that Nibiru is a real planet, saying, if it were, the agency "would have been tracking it for at least the past decade, and it would be visible by now to the naked eye."
