Will the world end on Sept. 23? Conspiracy theorists say yes

NASA says not so fast

If you had plans this weekend, you may want to cancel them, because according to conspiracy theorist and self-described researcher David Meade, the world is ending on Saturday.

Meade details in his book, "Planet X - The 2017 Arrival," how Planet X -- otherwise referred to as Nibiru -- will devastate the Earth, changing the landscape as we know it. NASA, however, has debunked the theory the planet even exists.

"Nibiru, a purported large object headed toward Earth, simply put - does not exist," a NASA blog post dispelling another 2012 doomsday theory said. "There is no credible evidence - telescopic or otherwise - for this object's existence. There is also no evidence of any kind for its gravitational affects upon bodies in our solar system"

But, Meade insists his theory of the world ending is different from others.

"What's different is that this Revelation 12:1 sign is completely absolutely different," Meade said in an interview with an Irish radio show host. "It pinpoints the beginning of the day of the lord the 7 year tribulation to Sept. 23 and planet X is the main cause, or factor, of the trumpet judgment."

Meade references the following Bible verse to bolster his claims the world will end:

A great sign appeared in heaven: a woman clothed with the sun, with the moon under her feet and a crown of twelve stars on her head.

Meade's theory suggests that the alignment of Virgo and Leo symbolizes Revelation 12:1 -- Virgo being the woman clothed with the sun and the Leo constellation being the crown of 12 stars.

Meade says Sept. 23 is the beginning of the end -- while not totally wiping out the planet, Nibiru, according to Meade, will trigger a series of Earth-changing events.

“The world is not ending, but the world as we know it is ending,” Meade told the Washington Post, adding later: “A major part of the world will not be the same the beginning of October.”

Meade told an Irish talk show he will go to the mountains to prepare for the event and said he can't fathom a reality where Nibiru doesn't change the world.

NASA has a running project called the Near-Earth Object Program that provides information on objects near the Earth.

"Today NASA astronomers are carrying out a survey called the Spaceguard Survey to find any large near-Earth asteroids long before they hit," NASA said in a blog post addressing 2012 doomsday theories. "We have already determined that there are no threatening asteroids as large as the one that killed the dinosaurs. All this work is done openly with the discoveries posted every day on the NASA Near-Earth Object Program Office website."
