NASA is out with a video detailing how the world did not end on the 21st of December. The YouTube video is basically the space agency’s way of saying “We told you so” and was originally going to be released on the 22nd. For whatever reason, it’s out now — over a week before many believe the world will be hit by some sort of catastrophe.

The video is the brainchild of NASA scientists who gathered recently for a Google Hangout. The event and the video that resulted were aimed at debunking various end of the world theories, most of them based on what NASA says are misinterpretations of the Mayan calendar.
