It has been the most talked about topic that this world is going to end on Dec.21, 2012. Here, I would tell you 5 best reasons, why it will not happen:
Mayans never claimed it: The Mayans had many calendars they used, one of which was known as the “long count” calendar, which measures very long periods of time. According to this calendar (which has been known to archeologists for decades, by the way) the Earth’s “fifth sun” would end at the Winter solstice, December 21, 2012, at which point a new, sixth 5,125-year cycle would begin. What significance this had to the Mayans is a source of some debate, but it is the general consensus that they did not attribute to it any catastrophic events. Most likely, they simply considered it a time for spiritual renewal or introspection, which doesn’t sound all that dangerous to me. The teaching that the Mayan’s believed it was the end of time, then, appears to be a largely westernized misreading (or deliberate misrepresentation) of the significance of the Mayan calendar and Mayan beliefs associated with it.
Nostradamus never picked 2012: It has been popularly believed that Nostradamus, the famous sixteenth century French mystic, suggested the end would come in 2012, perfectly coinciding with the Mayan date, which, if true, would be very spooky indeed. However, in reading through Nostradamus’ many quatrains, nowhere does he specifically mention the year 2012 or even suggest that the end would come around that time. In fact, his predictions extend all the way to the year 3797, making it seem we have some time yet before the end is neigh. Additionally, his writings are so obscure as to make any interpretation little better than a guess. Most of them are likely referring to events that took place in his lifetime, with the rest being so vague that they can be made to fit any time frame the reader so desires.
Earth isn’t easy to destroy: Sure, there are things that could do the planet in, but Earth is a lot hardier a place than many give it credit for. After all, it’s been here for four billion years now, had its clock repeated cleaned by asteroids and comets, endured climactic changes of biblical proportions, and even survived a collision with another planet that created our own moon, and yet it keeps on ticking. And you think a few melting ice caps and puny nuclear weapons are going to do it in? Please…
People who suggest the end is coming don’t know what they’re talking about:Unfortunately, human beings have a tendency to invest great authority in people who can convince them they are prophecy “experts” or have some sort of hidden knowledge others do not possess that allows them to read the future. Many of these people are sincere individuals who simply misinterpret ancient bible texts, while others are deluded crazies who only want to include others in their fantasy world. A few are even unscrupulous charlatans out to make a quick buck. The bottom line is, however, that nobody really knows what the future holds regardless of who they are or what methodology they use. There simply is no evidence that anyone has ever successfully prophesied some future event (beyond some short-term political or military events easily surmised by gauging current international trends) with anything approaching clarity or accuracy.
Reversal of the magnetic poles would not be catastrophic: It seems that every few hundred thousand years or so, the Earth’s magnetic field dwindles to practically nothing and then gradually reappears with the north and south poles flipped. Now this flipping of the magnetic poles—which appears to have last happened about 780,000 years ago—isn’t particularly dangerous, but this brief period—about a century or so in duration—of decreased magnetic fields could threaten life on the planet, for without magnetic protection, particle storms and cosmic rays from the sun, as well as even more energetic subatomic particles from deep space, would strike Earth’s atmosphere, eroding the already beleaguered ozone layer and causing all sorts of problems to both man and beast (especially among those creatures that navigate by magnetic reckoning). Further, scientists estimate that we are overdue for such an event and have also noticed that the strength of our magnetic field has decreased about 5 percent in the past century, possibly signaling that such an event may be in our immediate future—within a few centuries if not sooner. However, in being so gradual, should scientists in the future discover that such a shift is in the works, there should be plenty of time to take the necessary precautions to avoid the most destructive effects by moving underground or off planet, or perhaps strengthening the planet’s atmospheric defenses through the use of exotic, futuristic technologies. In any case, it isn’t something we need to worry about in the short term—though it could be a concern for those living a few hundred or even thousands of years from now.
