why does everyone think the world will end in 2012
Here are the details, again from Wikipedia:
Some people have interpreted the galactic alignment apocalyptically, claiming that when it occurs, it will somehow create a combined effect between the Sun and the at the center of our galaxy (known as ), thus creating havoc on Earth. Apart from the fact noted above that the "galactic alignment" already happened in 1998, the Sun's apparent path through the zodiac as seen from Earth does not take it near the true galactic center, but rather several degrees above it. Even if this were not the case, Sagittarius A* is 30,000 from Earth and would have to be more than 6 million times closer to cause any gravitational disruption to Earth's Solar System. This reading of the alignment was included on the History Channel documentary, Decoding the Past. However, John Major Jenkins has complained that a science fiction writer co-authored the documentary, and he went on to characterize it as "45 minutes of unabashed doomsday hype and the worst kind of inane sensationalism". Some believers in a 2012 doomsday have used the term "galactic alignment" to describe a very different phenomenon proposed by some scientists to explain a pattern in supposedly observed in the. According to, mass extinctions are not random, but recur every 26 million years. To account for this, it suggests that vertical oscillations made by the Sun on its of the galactic center cause it to regularly pass through the galactic plane. When the Sun's orbit takes it outside the galactic plane which bisects the, the influence of the is weaker. However, when re-entering the galactic disc as it does every 20-25 million years it comes under the influence of the far stronger "disc tides", which, according to mathematical models, increase the flux of comets into the inner Solar System by a factor of 4, thus leading to a massive increase in the likelihood of a devastating comet impact.
However, this "alignment" takes place over tens of millions of years, and could never be timed to an exact date. Evidence shows that the Sun passed through the plane bisecting the galactic disc only three million years ago and is now moving farther above it. A third suggested alignment is some sort of planetary occurring on 21 December 2012; however, there will be no conjunction on that date. Multi-planet alignments did occur in both 2000 and 2010, each with no ill result for the Earth. is the planet in the Solar System; larger than all other planets combined. When Jupiter is near, the difference in gravitational force that the Earth experiences is less than 1% of the force that the Earth feels daily from the Moon. Another idea tied to 2012 involves a (often incorrectly referred to as a by proponents), possibly triggered by a massive, that would release an energy equal to 100 billion. This belief is supposedly supported by observations that the Earth's is weakening, which could precede a reversal of the north and south, and the arrival of the next, which is expected sometime around 2012. Most scientific estimates, however, say that geomagnetic reversals take between 1,000 and 10,000 years to complete, and do not start on any particular date. Furthermore, the U. S. now predicts that the will peak in May 2013, not 2012, and that it will be fairly weak, with a below-average number of.
In any case, there is no scientific evidence linking a solar maximum to a geomagnetic reversal, which is driven by forces entirely within the Earth. Instead, a solar maximum would be mostly notable for its effects on satellite and cellular phone communications. David Morrison attributes the rise of the solar storm idea to physicist and science popularizer, who claimed in an interview with that a solar peak in 2012 could be disastrous for orbiting satellites. Some believers in doomsday in 2012 claim that a planet called Planet X, or Nibiru, will collide with or pass by Earth in that year. This idea, which has appeared in various forms since 1995, initially predicted Doomsday in May 2003, but proponents later abandoned that date after it passed without incident. The idea originated from claims of channeling of and has been widely ridiculed. Astronomers have calculated that such an object so close to Earth would be visible to anyone looking up at the night sky. For what it's worth, we don't find any of those concerns particularly compelling. But we've been wrong before. If you're really worried, you can take advantage of America's stocked shelves to hoard some food. That way, if we do get sucked into a black hole, at least you won't be hungry.

In a video published on YouTube, the space agency sought to calm fears в triggered by the supposed end of the Mayan calendar в that Christmas was about to be spoiled by the disintegration of Earth and the extinction of its 7 billion population.
The film was scheduled to be published on 22 December 2012, explaining why the world didn't end the previous day. "If you're watching this video it means one thing в the world didn't end yesterday," runs the commentary. But Nasa is so confident in its prediction that it has released it now. The prediction that the world would end four days before Christmas 2012 в potentially wreaking havoc with gift buying and travel plans в is a long-standing misconception, Nasa explains. An accompanying post on the agency's website, titled Beyond 2012: Why the World Won't End, says that 21 December this year has been labelled as the end of all things because the Mayan calendar ends on this date. But "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," Nasa says. Instead, it just starts over again. Another factor in the end of the world prophecy comes from claims that a "supposed planet" called Nibiru is heading for Earth, hellbent on destruction. "This catastrophe was initially predicted for May 2003, but when nothing happened the doomsday date was moved forward to December 2012," and linked to the end of the Mayan calendar, Nasa said. As astrobiologist David Morrison puts it in the Nasa video: "If there were anything out there like a planet headed for earth it would already be one of the brightest objects in the sky. Everybody on earth could see it. You don't need to ask the government. Just go out and look. It's not there. "
