One of the predictions related with the end of the world on 21 December is the existence of the so-called Planet X or Nibiru, which is supposed to hit the Earth in a day and a half.
The story of Nibiru began in 1976, when the author Zecharia Sitchin published his interpretations of Babylonian and Sumerian mythology. He denied any connections between his investigation and the Doomsday.
In 1995, Nancy Lieder, founder of the website ZetaTalk, affirmed that, through an implant in her brain, an extra-terrestrials told her about an object which should destroy the human kind in May 2003: Planet X.
Nine years later we are still here, so maybe the object changed its course or this was just a theory. After that, the date was moved back to 2012 and was linked to the end of the Mayan calendar.
Scientists are trying to explain that Nibiru-Earth collision is an Internet hoax, and, if it was real, astronomers would have been tracking it for at least the past decade. wandering planets exists, but the closest they can come to the Earth is about 6 billion kilometres.
However, in May, Rodney Gomes, an astronomer at the National Observatory of Brazil in Rio de Janeiro, claimed that a planet four times the size of Earth may be travelling through the edges of the solar system beyond Pluto.
Besides Gomes' arguments were convincing, his colleagues said that more evidence is needed to consider the planet as something real.
Astronomers have been studying small icy bodies that lie beyond Neptune, including the tiny planet Sedna. But this doesn't mean that one of them will collied with Earth.
NASA's attempts to convince citizens that the world won't end on 21 December have gone a step further. They have already released a video for the day after the end of the world, explaining why we are still alive.
“If you are watching this video, it means one thing: the world didn't end yesterday”, starts the video, which affirms that all the theories around the issue were a “misconception from the very beginning.”
“None of the thousands ruins, tablets and standing stones that the archaeologists have examined foretold the end of the world, modern science agrees”, NASA explains.
According to Don Yeomans, Head of NASA's Near Earth Object Programme, stated that “nor asteroids or comets were on a collision course with Earth. Neither is a rock planet on its way to destroy us.”
“If there were anything out there like a planet headed for Earth, it would be already one of the brightest objects in the sky”, said NASA astro-biologist David Morris. “Everybody on Earth could see it. You don't need to ask the government, just go out and look, is not there.”
