It's the end of the world as we know it, according to Mayan's calendar. Another thing, which is my theory is that they didn't have time to finish their calendar because of Spanish conquerors. These 10 doomsday predictions didn't happen, but people were scared. See what people though it will be their the end.
1. Mount Vesuvius buries Pompeii (79 A.D.)
The deluge of volcanic ash "shrouded the city in a darkness … like the black of closed and unlighted rooms," according to one witness, echoing the predictions of Roman philosopher Seneca that the Earth would go up in smoke, according to National Geographic.
2. Plagues and Fires (1666)
According to the Bible's Book of Revelation, the number 666 is described as the "mark of the beast" — which put Christian Europeans into a state of panic as the year 1666 approached, according to Time Magazine. The plague which was few years before didn't help in stopping the panic.
On Sept. 2, 1666, a fire started in a London bakery, destroying more than 13,000 buildings and tens of thousands of homes over the course of three days, Time reported. However, the disastrous fire claimed only 10 lives. The Devil didn't do his job well.
3. Halley's Comet cuts it close (1910)
Halley's comet, named after British astronomer Edmond Halley, wows the Earth every 75 years, or so. However, 1910's arrival of the brilliant star caused more panic than excitement, National Geographic reported, as many speculated that the comet's tail contained a gas "that would impregnate the atmosphere and possibly snuff out all life on the planet," according to French astronomer Camille Flammarion.
In fact, the 1910 comet came especially close to the Earth, whose orbit carried the comet's 24-million-mile-long tail for six hours on May 19, Wired reported. A close call, but the planet stayed intact.
4. Jehovah's Witnesses prophesy Christ's Kingdom (1914)
Jehovah's Witnesses were founded in 1870 and they started with door-to-door warnings that a bloody end of the world is imminent and the year predicted was 1914. The year came, but the world is still here.
5. Pat Robertson's prediction (1982)
TV Evangelist and former Republican presidential candidate Pat Robertson is known for saying some really disputable things. But his 1980 announcement was far out the craziest one.
"I guarantee by the end of 1982 there is going to be a judgment on this world," Robertson had said, predicting Armageddon followed by seven "nightmare years" of suffering. After misjudging that apocalypse, Robertson revived his Doomsday prophesies: In 2006, the evangelist said God had warned him of large storms and tsunamis. In 2008 predicted "worldwide violence" and a stock-market crash by 2010.
6. Heaven's Gate Hale-Bopp Suicide (1997)
Heaven's Gate is a cult founded by Marshall Applewhite, believed that the earth was going to be 'wiped clean' by aliens, and that a UFO riding the tail of the Hale-Bopp comet would transport their souls to the next life.
Their Doomsday predictions turned tragic when 39 members of the sect committed mass suicide on March 26, 1997, in an upscale mansion in San Diego, California. It was one of the worst mass suicides in United States' history.
7. "The True Way" Taiwanese cult (March 31, 1998)
Hon-Ming Chen established his "True Way" cult in Taiwan, blending beliefs from Buddhism and Taoism with UFO conspiracy theories. Chen believed that God would appear on American cable television on the morning of March 31, 1998. He relocated his cult to Garland, Texas — because the town's name sounded like "God Land" to them — to wait for the Rapture to happen.
8. Y2K Scare (January 1, 2000)
In 1984, a computer-trade column warned that a computer calculation error on Jan. 1, 2000 would lead to mass chaos and send machines and technology worldwide grinding to a halt as they reached 00 due to their use of two digits for years (i.e. 98, 99, 00).
9. The Large Hadron Collider's Big Bang (2009)
Scientists at the CERN in Geneva built a particle accelerator that would allow them to study the world's smallest known particles. Their plan to have subatomic particles called "hadrons" collide led some critics to believe the experiment would cause a black hole that would ultimately destroy the earth.
The experiment went forward, creating temperatures a million times hotter than the center of the Sun (which hadn't been reached since the first billionths of a second following the Big Bang).
No significant chunks of the earth were harmed.
10. The Rapture (May 21, 2011)
Radio preacher Harold Camping was the latest figure to predict Judgment Day, which he was expecting on May 21, 2011 based on his application of numerology to readings of the Bible.
Now, we are waiting for December 12, 2012. As it appears this will be the day the world ends according to Mayan calendar. Folks stay here and see what is next happen or wait for the next doomsday! You see how things are changing, you never know. Even the doomsday is unpredictable, you can't trust it. While you are waiting try to have fun and fulfill your bucket list!
