DOOMSDAY!! Its gone...

They say, finally the day is coming when the world is supposed to end. The doomsday is 21st December 2012.This date is regarded as the end-date of a 5125 year long cycle in the Mesomerican long count calendar. This date marks the beginning of a new era in which Earth and its inhabitants may undergo a positive physical or spiritual transformation and will include the arrival of the next solar maximum which is the interaction between Earth and the black hole at the centre of the galaxy or earth's collision with a planet called "Nibiru". This idea of collision with the planet Nibiru originated from claims of channelling of alien beings and has been widely ridiculed. December 2012 marks the conclusion of a b'ak'tun-a time period in the Mesoamerican Long count calendar. There is a strong tradition of "world ages" in Mayan literature. According to the PopolVuh, a compilation of the creation accounts of the K'iche' Maya of the Colonial-era highlands, we are living in the fourth world. The PopolVuh describes the gods first creating three failed worlds, followed by a successful fourth world in which humanity was placed. In the Maya Long Count, the previous world ended after 13 b'ak'tuns, or roughly 5,125 years. The Long Count's "zero date" was set at a point in the past marking the end of the third world and the beginning of the current one, which corresponds to 11 August 3114 BC in the Gregorian calendar. This means that the fourth world will also have reached the end of its 13th b'ak'tun, or Mayan date 13.0.0.0.0, on 21 December 2012. In 1957, Mayanist and astronomer Maud Worcester Makemson wrote that "the completion of a Great Period of 13 b'ak'tuns would have been of the utmost significance to the Maya". In 1966, Michael D. Coe wrote in The Maya that "there is a suggestion ... that Armageddon would overtake the degenerate peoples of the world and all creation on the final day of the 13th [b'ak'tun]. Thus our present universe would be annihilated in December 2012 when the Great Cycle of the Long Count reaches completion."

"Time wave zero" is a numerological formula that purports to calculate the ebb and flow of "novelty", defined as increase over time in the universe's interconnectedness, or organized complexity. According to Terence McKenna, the universe has a teleological attractor at the end of time that increases interconnectedness, eventually reaching a singularity of infinite complexity in 2012, at which point anything and everything imaginable will occur simultaneously. He conceived this idea over several years in the early to mid-1970s whilst using psilocybin mushrooms and DMT.

McKenna expressed "novelty" in a computer program which purportedly produces a waveform known as "time wave zero" or the "time wave". Based on McKenna's interpretation of the King Wen sequence of the I Ching, an ancient Chinese book on divination, the graph appears to show great periods of novelty corresponding with major shifts in humanity's biological and socio-cultural revolution. He believed that the events of any given time are resonantly related to the events of other times, and chose the atomic bombing of Hiroshima as the basis for calculating his end date of November 2012. When he later discovered this date's proximity to the end of the 13th b'ak'tun of the Maya calendar, he revised his hypothesis so that the two dates matched.
The 1975 first edition of The Invisible Landscape refers to 2012 (but no specific day during the year) only twice. In the 1993 second edition, McKenna employed Sharer's date of 21 December 2012 throughout.
In India, the guru KalkiBhagavan has promoted 2012 as a "deadline" for human enlightenment since at least 1998.Over 15 million people consider Bhagavan to be the incarnation of the god Vishnu and believe that 2012 marks the end of the Kali Yuga, or degenerate age.
The phenomenon has spread widely since coming to public notice, particularly on the Internet.  "Ask an Astro-biologist", a NASA public outreach website, has received over 5000 questions from the public on the subject since 2007, some asking whether they should kill themselves, their children or their pets. In May 2012, an Ipsos poll of 16,000 adults in 21 countries found that 8 percent had experienced fear or anxiety over the possibility of the world ending in December, 2012, while an average of 10 percent agreed with the statement "the Mayan calendar, which some say ‘ends’ in 2012, marks the end of the world", with responses as high as 20 percent in China, 13 percent in Russia, Turkey, Japan and Korea, and 12 percent in the United States, where sales of private underground blast shelters have increased noticeably since 2009. At least one suicide has been directly linked to fear of a 2012 apocalypse, with several more anecdotally reported. A panel of scientists questioned on the topic at a plenary session at the Astronomical Society of the Pacific contended that the Internet has played a substantial role in allowing this doomsday date to gain more traction than previous similar panics.
In Brazil, the Mayor of the City of São Francisco de Paula, DécioColla, Rio Grande do Sul, has mobilized the population to prepare for the end of the world by stocking up on food and supplies. In the city of Corguinho, in the MatoGrosso do Sul, a colony is being built for survivors of the tragedy. In Alto Paraíso de Goiás, the hotels also make specific reservations for prophetic dates. On 11 October 2012, in the Brazilian city of Teresina, police interrupted what was believed to have been an attempted mass suicide by up to one hundred members of a cult headed by self-proclaimed prophet Luis Pereira dos Santos, who predicted the end of the world on the feast day of Our Lady of Aparecida. Santos was subsequently arrested.

The UFO conspiracy TV series The X-Files cites December 22, 2012 as the date for an alien colonization of the Earth and mentions the Mayan calendar "stopping" on this date.
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).^[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.In 2012, the National Geographic Channel launched a show called Doomsday Preppers, a documentary series about survivalists preparing for various cataclysms, including the 2012 doomsday.
Hundreds of books have been published on the topic. The bestselling book of 2009, Dan Brown's The Lost Symbol, featured a coded mock email number (2456282.5) that decodes, according to The Washington Post, as "December 21, 2012".
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.Although the campaign was heavily criticized, the film became one of the most successful of its year, grossing nearly $770 million worldwide.
2011 film Melancholia features a plot in which a planet emerges from behind the Sun onto a collision course with Earth. 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". 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 going to stand around till 2012 A.D.? / What are you waiting for, a certain shade of green?"). In February 2012, American automotive company GM aired an advertisement during the annual Super football game in which a group of friends drive Chevrolet Silverados through the ruins of human civilization 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.)
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. 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.
