Roland Emmerich is famous for directing disaster films.

Water rushed into the Himalayas
the arks
When people rebirth from the disaster and bath the first sunshine.
And even the NASA have to denied that
But today we do not talk about the film 2012.
Are there any threats to the Earth in 2012? Many Internet websites say the world will end in December 2012.
• What is the polar shift theory? Is it true that the earth’s Magnetic field will a 180degree rotation around?
A reversal逆转 in the polar of Earth is impossible. There are slow movements of the continents (for example Antarctica was near the equator hundreds of millions of years ago), but that is irrelevant to claims of reversal of the rotational poles. However, many of the disaster websites pull a bait-and-shift to fool people. They claim a relationship between the This is the original site of NASA rotation and the magnetic polarity of Earth, which does change irregularly, with a magnetic reversal taking place every 400,000 years on average. As far as we know, such a magnetic reversal doesn’t cause any harm to life on Earth. A magnetic reversal is very unlikely to happen in the next few millennia, anyway.
Impressive movie special effects aside, Dec. 21, 2012, won‘t be the end of the world as we know. It will, however, be another winter solstice(冬至).
Where did the universe come from？ How it going to be? And how about our solar system ?
• The sun have 4 billion year to maintain the status quo. • That is to say our earth have 4 billion to survival at list. • So 2012 well not be the end of the world.
What is the origin of the prediction that the world will end in 2012?
Does the Mayan calendar end in December 2012?
Just as the calendar you have on your kitchen wall does not cease to exist after December 31, the Mayan calendar does not cease to exist on December 21, 2012. This date is the end of the Mayan longcount period but then -- just as your calendar begins again on January 1 -- another long-count period begins for the Mayan calendar.
Today we predict it on the other hand
A Brief History of Time
Where did the universe come from? How and why did it begin? Will it come to an end, and if so, how? Among the topics gracefully covered are gravity, black holes, the Big Bang, the nature of time, and now the physicists‘ searching a grand unifying theory(统一场
Do you believe it
Many people believe that the December 21 of 2012 is the end of the world after seeing the film 2012 . And some even post a satellite photo showing that the government is building the arks in China's Tibet.
What are you doing on the morning of Dec. 21, 2012?
Maybe you are just having breakfast with you boy/girl friend in our school canteepredictions in history. But all of them were proved to be a lie.
What dose the NASA denied in it web side
Is the Earth in danger of being hit by a unknown comets in 2012? Is there a danger from giant solar storms predicted for 2012? What is the polar shift theory? Is it true that the earth’s Magnetic field will a 180-degree rotation around.
论).
Is the Earth in danger of being hit by comets in 2012?
• As a small mass of the planet, our earth have its own advantages to aloof from the Comets’ impact. And there is no evidence that a comet is closing to Earth. Or that maybe the extinction(灭绝、灭亡) of the dinosaurs are not by the Comets .
