NASA has warned us time and time again that the Mayan apocalypse, predicted to fall on 12/21/12, is not scientifically possible. It's not gonna happen, people! And yet, Twitter users everywhere are spending a disproportionate amount of time coming up with completely original Mayan joke material. Now, there is Instapocalypse, a site that culls Instagram photos published with the #apocalypse hashtag, because we all get the Internet we deserve.

So far the site is pretty sparse, populated by some pics of weird expiration dates on foods and a shoddy-looking apocalypse countdown thing created by something called Versagram. We do, however, have to agree with this photo, which correctly pronounces that 12/21/12 will be the most annoying day in Facebook history. Also, this cat is cute!

If a fiery asteroid does end up hurtling towards earth on 12/21/12, I think we can all die happy knowing that we contributed to such a meaningful project.

NOPE, ALL BULLSHIT.

We're less than a month away from December 21, which some people genuinely still seem to believe will be the end of the world, as predicted by the Mayans. And so, NASA is spending the holiday season--a time when everyone ought to be sneaking nips of eggnog and picking out their ugliest season sweaters--making one last attempt to diffuse everyone's paranoia.

What, Neil deGrasse Tyson, super scientist, wasn't a respectable enough authority?

CNET reports that yesterday, the agency held a Google+ Hangout specifically to discuss rumor's of the earth's imminent demise. On the call were experts in asteroids and also an archaeoastronomer. All of them agreed: The world is not ending. There'll be no wandering planets or rogue asteroids or boiling seas or shifting tectonic plates before the end of the month, so go right ahead and wrap those presents.

And actually, it sounds like all this is really starting to upset the agency's resident astrobiologist:

"In particular I'm concerned about the young people who write to me and say that they are terribly afraid," Morrison said in response to a question during a Google+ Hangout NASA held yesterday specifically to address 2012 apocalyptic hoaxes. "They can't sleep, they can't eat, some of them say they are contemplating suicide."

Again: The world is not ending. Repeat: The world is not ending. Go back to your lives, citizens.
