VIDEO: NASA Says The World Won't End On Dec. 21 (Phew!)

If you've been stocking up on supplies for the end of the world, NASA has news for you: You won't need them. While many doomsayers have touted the end of the Mayan calendar on Dec. 21 as the day of the apocalypse, NASA scientists believe these theories are simply incorrect.

In fact, NASA is so confident, that it's already released the video for the day after the rumored apocalypse. The 5-minute short is called Why the World Didn't End Yesterday and it details the true meaning behind the Mayan Calendar. In fact, the calendar doesn't end—it just starts over.

The video also shares how NASA experts disprove several popular theories of how the world might end. They see no proof that an asteroid, comet, rogue planet or sun could destroy the planet next Friday. If anything was coming toward earth, they said, you would already see it in the sky.

The Mayan Calendar began in 3114 BC and Dec. 21, 2012 will mark the end of more than a 5,000-year era. Mexico,  Belize, Guatemala, El Salvador and Honduras will all have celebrations to honor this date.
