Some people have interpreted the galactic alignment apocalyptically, claiming that when it occurs, it will somehow create a combined gravitational effect between the Sun and the supermassive black hole at the center of our galaxy (known as Sagittarius A* ), thus creating havoc on Earth. [ 91 ] 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. [ 63 ] Even if this were not the case, Sagittarius A* is 30,000 light years from Earth, and would have to be more than 6 million times closer to cause any gravitational disruption to Earth's Solar System. [ 92 ] [ 93 ] 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". [ 94 ]

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 mass extinctions supposedly observed in the fossil record . [ 95 ] According to this hypothesis , 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 250-million-year orbit 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 galactic disc , the influence of the galactic tide 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 Oort cloud 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. [ 96 ] However, this "alignment" takes place over tens of millions of years, and could never be timed to an exact date. [ 97 ] 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. [ 98 ]

A third suggested alignment is some sort of planetary conjunction occurring on 21 December 2012; however, there will be no conjunction on that date. [ 10 ] Multi-planet alignments did occur in both 2000 and 2010, each with no ill result for the Earth. [ 99 ] Jupiter is the largest planet in the Solar System; larger than all other planets combined. When Jupiter is near opposition , the Earth experiences less than 1% the gravitational force it feels daily from the Moon. [ 100 ]

Geomagnetic reversal

Another idea tied to 2012 involves a geomagnetic reversal (often incorrectly referred to as a pole shift by proponents), possibly triggered by a massive solar flare , that would release an energy equal to 100 billion atomic bombs . [ 101 ] This belief is supposedly supported by observations that the Earth's magnetic field is weakening, [ 102 ] which could precede a reversal of the north and south magnetic poles .

Critics, however, claim that geomagnetic reversals take up to 7,000 years to complete, and do not start on any particular date. [ 103 ] Furthermore, the US National Oceanic and Atmospheric Administration now predicts that the solar maximum will peak in May 2013, not 2012, and that it will be fairly weak, with a below-average number of sunspots . [ 104 ] 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. [ 105 ] Instead, a solar maximum would be mostly notable for its effects on satellite and cellular phone communications. [ 106 ] David Morrison attributes the rise of the solar storm idea to physicist and science popularizer Michio Kaku , who claimed in an interview with Fox News that a solar peak in 2012 could be disastrous for orbiting satellites. [ 90 ]

Planet X/Nibiru

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. [ 107 ] The idea originated from claims of channeling of alien beings and has been widely ridiculed. [ 107 ] [ 108 ] Astronomers have calculated that such an object so close to Earth would be visible to anyone looking up at the night sky. [ 107 ]

Other catastrophes

The Pleiades star cluster
The Pleiades , a star cluster whose supposed influence is sometimes tied to the 2012 phenomenon

Author Graham Hancock , in his book Fingerprints of the Gods , interpreted Coe's remarks in Breaking the Maya Code [ 109 ] as evidence for the prophecy of a global cataclysm. [ 110 ] Filmmaker Roland Emmerich would later credit the book with inspiring his 2009 disaster film 2012 . [ 111 ]

Other speculations regarding doomsday in 2012 have included predictions by the Web Bot project, a computer program that purports to predict the future using Internet chatter. However, commentators have rejected the programmers' claims to have successfully predicted natural disasters, which web chatter could never predict, as opposed to human-caused disasters like stock market crashes. [ 112 ]

Also, the 2012 date has been loosely tied to the long-running concept of the Photon Belt , which predicts a form of interaction between Earth and Alcyone , the largest star of the Pleiades cluster . [ 113 ] Critics have argued that photons cannot form belts, that the Pleiades, located more than 400 light years away, could have no effect on Earth, and that the Solar System, rather than getting closer to the Pleiades, is in fact moving farther away from them. [ 114 ]

Some media outlets have tied the fact that the red supergiant star Betelgeuse will undergo a supernova at some point in the future to the 2012 phenomenon. However, while Betelgeuse is certainly in the final stages of its life, and will die as a supernova, there is no way to predict the timing of the event to within 100,000 years. [ 115 ] To be a threat to Earth, a supernova would need to be as close as 25 light years to the Solar System. Betelgeuse is roughly 600 light years away, and so its supernova will not affect Earth. [ 116 ] In December 2011, NASA's Francis Reddy issued a press release debunking the possibility of a supernova occurring in 2012. [ 117 ]

Another claim involves alien invasion . In December 2010, an article, first published in examiner.com and later referenced in the English-language edition of Pravda [ 118 ] claimed, citing a Second Digitized Sky Survey photograph as evidence, that SETI had detected three large spacecraft due to arrive at Earth in 2012. [ 119 ] Astronomer and debunker Phil Plait noted that by using the small-angle formula , one could determine that if the object in the photo was as large as claimed, it would have had to be closer to Earth than the Moon, which would mean it would already have arrived. [ 119 ] In January 2011, Seth Shostak , chief astronomer of SETI, issued a press release debunking the claims. [ 118 ]

Cultural influence

The phenomenon has produced hundreds of books, as well as hundreds of thousands of websites. [ 90 ] "Ask an Astrobiologist", a NASA public outreach website, has received over 5000 questions from the public on the subject since 2007, [ 113 ] some asking whether they should kill themselves, their children or their pets. [ 90 ]

In the United States , sales of private underground blast shelters have increased noticeably since 2009. In December 2009, Robert Vicino founded Vivos , a company that claims to offer discount shelters for the less well off. Their site features a countdown clock to December 2012. [ 120 ]

In Brazil , the Mayor of the City of São Francisco de Paula , Décio Colla, Rio Grande do Sul , has mobilized the population to prepare for the end of the world by stocking up on food and supplies . [ 121 ] [ 122 ] In the city of Corguinho , in the Mato Grosso do Sul , a colony is being built for survivors of the tragedy. [ 123 ] In Alto Paraíso de Goiás , the hotels also make specific reservations for prophetic dates. [ 124 ]

In 2011, the Mexico tourism board stated its intentions to use the year 2012, without its apocalyptic connotations, as a means to revive Mexico's tourism industry, which had suffered as the country gained a reputation for drug wars and kidnapping. The initiative hopes to draw on the mystical appeal of the Maya ruins. [ 125 ] On 21 December 2011, the Maya town of Tapachula in Chiapas activated an eight-foot digital clock counting down the days until the end of b'ak'tun 13, while in Izapa , a nearby archaeological site, Maya priests burned incense and prayed. [ 126 ]

In media

Since coming to notice, the 2012 phenomenon has been discussed or referenced in several media. Several TV documentaries, as well as many contemporary fictional references to the year 2012 refer to 21 December as the day of a cataclysmic event.

The History Channel has aired a handful of special series on doomsday that include analysis of 2012 theories, such as Decoding the Past (2005–2007), 2012, End of Days (2006), Last Days on Earth (2006), Seven Signs of the Apocalypse (2007), and Nostradamus 2012 (2008). [ 127 ] The Discovery Channel also aired 2012 Apocalypse in 2009, suggesting that massive solar storms , magnetic pole reversal , earthquakes, supervolcanoes , and other drastic natural events may occur in 2012. [ 128 ] In 2012 the National Geographic Channel launched a show called Doomsday Preppers , a documentary series about people preparing for various cataclysms, including the 2012 doomsday. [ 129 ]

The bestselling book of 2009, [ 130 ] Dan Brown 's The Lost Symbol , featured 2012 as a date for an apocalypse.

The 2009 disaster film 2012 was inspired by the phenomenon, and advance promotion prior to its release included a stealth marketing campaign in which TV spots and websites from the fictional "Institute for Human Continuity" called on people to prepare for the end of the world. As these promotions did not mention the film itself, many viewers believed them to be real and contacted astronomers in panic. [ 131 ] [ 132 ] Although the campaign was heavily criticized, [ 90 ] the film became one of the most successful of its year, grossing nearly $770 million worldwide. [ 133 ]

Lars von Trier 's 2011 film Melancholia features a plot in which a planet emerges from behind the Sun onto a collision course with Earth. [ 134 ] Announcing his company's purchase of the film, the head of Magnolia Pictures said in a press release, "As the 2012 apocalypse is upon us, it is time to prepare for a cinematic last supper." [ 135 ]

The phenomenon has also inspired several pop music hits. As early as 1997, " A Certain Shade of Green " by Incubus referred to the mystical belief that a shift in perception would arrive in 2012 ("Are you gonna stand around till 2012 AD? / What are you waiting for, a certain shade of green?"). More recent hits include " 2012 (It Ain't the End) " (2010) performed by Jay Sean and " Till the World Ends " (2011) performed by Britney Spears .

In February 2012, American automotive company GM aired an advertisement during the annual Super Bowl football game in which a group of friends drive Chevrolet Silverados through the ruins of human civilisation following the 2012 apocalypse. (When the whereabouts of one of their friends is queried, it is revealed that he died because he drove a Ford .) [ 136 ]

Notes یادداشت ها

  • a The number 13 plays an important role in Mesoamerican calendrics; the tzolk'in , or sacred calendar, was divided into 13 months of 20 days each. The Mayan may cycle consisted of 13 k'atuns. The reason for the number's importance is uncertain, though correlations to the phases of the moon and to the human gestation period have been suggested. [ 137 ] [ 138 ]
  • b The Mayan calendar, unlike the Western calendar, used a zero. [ 13 ]
  • c Most Mayanist scholars, such as Mark Van Stone and Anthony Aveni , adhere to the "GMT (Goodman-Martinez-Thompson) correlation" with the Long Count, which places the start date at 11 August 3114 BC and the end date of b'ak'tun 13 at 21 December 2012. [ 139 ] This date is also the overwhelming preference of those who believe in 2012 eschatology, arguably, Van Stone suggests, because it falls on a solstice , and is thus astrologically significant. Some Mayanist scholars, such as Michael D. Coe , Linda Schele and Marc Zender , adhere to the "Lounsbury/GMT+2" correlation, which sets the start date at 13 August and the end date at 23 December. Which of these is the precise correlation has yet to be conclusively settled. [ 140 ]
  • d Coe's initial date was "24 December 2011." He revised it to "11 January AD 2013" in the 1980 2nd edition of his book, [ 141 ] not settling on 23 December 2012 until the 1984 3rd edition. [ 142 ] The correlation of b'ak'tun 13 as 21 December 2012 first appeared in Table B.2 of Robert J. Sharer 's 1983 revision of the 4th edition of Sylvanus Morley 's book The Ancient Maya . [
