Unlikely. This date comes from the ancient Mayan calendar which stops on Dec 21, 2012. There are some other obscure references to 2012, but no solid evidence of any kind.
Absolutely, you have my personal guarantee that the world, and the human population living in the world, will continue to survive after the year 2012. Any rumors that you may have heard that the world is going to end in 2012 are false.
There was never any real evidence that the world would end on December 21, 2012. It was just a silly conspiracy theory.
There is no evidence there will be any apocalypse in 2012; that is a myth. And there is also no evidence that any president, whether Obama or anyone else, could trigger such an event.
It is highly unlikely. There is no real evidence that any apocalyptic event will happen in 2012.
Sure; 2012 is as good as any year.
52 weeks, as there are in any year.
Not seriously; if you look on the Internet, you'll find websites that predict the end of the world in 2012. However, you can pick more or less any year (past, present or future) and someone's predicted the end of the world for then.
Nothing bad will happen to the Earth in 2012. Our planet has been getting along just fine for more than 4 billion years, and credible scientists worldwide know of no threat associated with 2012.
As it hasn't happened yet, it's impossible to know for certain. However, there is no scientific evidence whatsoever to support this ... one hesitates to dignify it by calling it a "theory"; it's basically a few crackpots misinterpreting Mayan mythology that even the Mayans themselves seem not to have been too concerned about. There's also some nonsense about something called "Planet X" or "Nabiru" which may or may not be related to the Mayan calendar issue, but there's no scientific evidence for it either so it's equally irrelevant.
There will be no 2012 disaster. 2012 will be just like any other year.
As any former year
