NOOOOOOO!!
I participate in Yahoo! Answers. I give answers to math & science questions mostly. And "will the world end in 2012" literally gets asked every 20 minutes or so. Go on to the "Astronomy" page any time of day and you'll see that 3 or 4 times on the front page. At last count, it has now been asked 40,000+ times. So I'm just a little sick of it.
Then I come here and see... a 2012 discussion. ARRRRRGH!
Other favorite rumors:
Nostradamus predicted it.
Merlin the Magician predicted it.
The Hopis predicted it.
The Book of Revelations predicted it.
The (some fictional ancient book that doesn't actually exist) predicted it.
Scientists say the poles will flip.
Scientists say there will be a killer flare.
All of the planets are going to align (doesn't happen. Ever.) and that will cause something or other (why?)
We'll cross the galactic plane (not for a few million years, sorry) and that will cause something or other (why?)
There's a killer planet that's going to hit us/cause the poles to flip/create giant killer tidal waves (where is it?)
Now with the hype for the 2012 movie coming out, we start getting questions like "I saw this commercial that the world is going to end in 2012 and I'm really scared. What are scientists doing about it?"
Or people saying "I saw this website. Is this for real? Some people say it's for a movie but I dunno. I'm too young to die."
http://www.instituteforhumancontinuity.org/They're apparently incapable of reading the "Copyright Sony Pictures" or "Explore the 2012 Movie Experience" lines at the bottom.
OK, rant over. I feel better now.
