NASA Says the World Will Not End on 12/21/12 [VIDEO]

NASA released a video last week dated December 22nd, and titled "Why the World Didn't End Yesterday."  They're so confident the world won’t end on Friday that they’ve already released a video (from the future, of course) to explain why we didn’t all die. I don't know about you--but I think we'll be ok. I trust NASA. Especially the science experts at NASA.  Do you?
