"On December 21, 2012, not the end of the world as we know it, however, is another winter solstice." That's how NASA denied the endless arguments about the "end of the world", and the reason is that I've heard of such a disaster have been so many that, in truth, not for science could not be so calm writing this article.
While we are on the eve of the expected December 21, I will make a top of the reasons why the world will not end, at least, in 2012, based on questions posed to NASA.
Question 1. Is there any threat to Earth in 2012? Many websites say the world will end in December 2012.
The world will not end in 2012. Our planet has been fine for more than 4 billion years, and credible scientists worldwide know of no threat associated with 2012.
Question 2. What is the origin of the prediction that the world will end in 2012?
The story started with claims that Nibiru, a supposed planet discovered by the Sumerians, is headed toward Earth. This catastrophe was initially scheduled for May 2003, but when nothing happened the doomsday date was moved to December 2012 and linked to the end of one of the cycles in the ancient Mayan calendar at the winter solstice in 2012 therefore the date scheduled for the end of the world December 21, 2012.
Question 3. Does the Mayan calendar end in December 2012?
Just as the calendar you have on the 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 long-count period, but then, as the calendar begins again on January 1, another long-count period begins for the Mayan calendar.
Question 4. ? NASA predicted a "blackout" of the Earth between December 23 to December 25?
No, not at all . Neither NASA nor any other scientific organization has predicted a blackout. False reports on the subject say that a kind of "alignment of the Universe" will cause a blackout. There is no such alignment. This is simply a message from NASA Administrator Charles Bolden encouraging people to prepare for emergencies, recorded as part of a government campaign for a more extensive preparation. Never mention a blackout.
Question 5. Could the planets align in a way that affects the Earth?
No such planetary alignments in the next few decades, and even if these alignments were to occur, their effects on the Earth would be negligible. A major alignment took place in 1962, for example, and another two that occurred during 1982 and 2000. Each December the Earth and sun align with the approximate center of the Milky Way, is an annual event of no consequence.
Question 6. Is there a brown dwarf or planet called Nibiru or Planet X or Eris that is approaching the Earth and threatening our planet with widespread destruction?
Nibiru and other stories about wayward planets are an Internet hoax. There is no factual basis for these claims. If Nibiru or Planet X were real and should be aimed at a direct encounter with Earth in 2012, astronomers would have been tracking the smallest details for at least the last decade and, indeed, such a phenomenon now would be visible. Obviously there. Eris is real, but it is a dwarf planet similar to Pluto that will remain in the outer solar system, the closest I can come to Earth is about 4 billion miles.
Question 7. What is the polar shift theory? Is it true that the earth's crust does a 180 degree turning around the core in a matter of days if not hours?
A change in the rotation of the Earth is impossible. There are slow movements of the continents (for example Antarctica was near the Ecuador hundred million years ago), but that is irrelevant to claims of reversal of the rotational poles. However, many of the websites that speak of disasters are just trying to fool people. They claim a relationship between the rotation and the magnetic polarity of Earth, which does change irregularly, with a magnetic reversal taking place every 400,000 years on average. For all we know, such a magnetic reversal does not cause any harm to life on Earth. Scientists believe that a magnetic reversal is very unlikely to happen in the next few millennia.
Question 8. Is the Earth in danger of being hit by a meteor in 2012?
The Earth has always been subject to impacts by comets and asteroids, although big hits are very rare. The last big impact was more than 65 million years, which led to the extinction of the dinosaurs. It has been determined that there are no threatening asteroids as large as the one that killed the dinosaurs. All this work is done openly with the discoveries posted every day on the website of the Office of the bar program of Near Earth Objects at NASA, so you can see for yourself that nothing is predicted to hit us in 2012.
Question 9. Is there a danger from giant solar storms predicted for 2012?
Solar activity has a regular cycle, with peaks approximately 11 years. Near these activity peaks, solar flares can cause disruption of satellite communications, although engineers are learning how to build electronics that are protected against most solar storms. But there is no special risk associated with 2012. The next solar maximum will occur in the 2013-2014 time frames and is predicted to be an average solar cycle, no different than previous cycles of history.
Anyway, I think that NASA cleared many doubts that are often caused by the mass media, without scientific support that have been terrorizing more than one.
