No doubt you’ve heard that the Mayan calendar ends in 2012 which is why there are plenty of people who jokingly (hopefully) say that the world will end in 2012. NASA is certain that that is not true and has already released a video in which they explain why the world will not end in 2012. The video is titled Why the World Didn’t End Yesterday. Check it out below.
On a related note. I just discovered a new series of NASA videos that take us on an explanatory tour of the electromagnetic spectrum. Those videos are embedded below.
