the core of the earth can have a twin?

k this paper was published only in yahoo.com, http://dsc.discovery.com/news/2009/01/06/earth-twin-cores.html I mean all those who believe Nibiru is real, suppose you are right, because before this article was published today, believers of other Nibiru was a planet called Nibiru, he said, another accident of the moon on the surface of the Earth and therefore have the moon and the asteroid belt. What do you think, and people who say this is stupid and a joke, think again time? http://i2.tinypic.com/82u6e60.jpg

This has nothing to do with Nibiru. The idea of a dual-core is, as they say, speculation, and most agree that if such a thing existed, it certainly will be merged into a single core at this point. an example of a Scientific spitting things popular authors claim "rewriting" our understanding. Well, no, it does not. If there was an exchange collision and some of the debris formed the moon and some of the remains sank into the earth, means that everything we have achieved no more. The moon is all we have of him and great of the material that made the moon was blown away from Earth. The second link I gave you is wrong. The planet Nibiru does not exist. At least there is no such thing could be here within solar system in the near future, or we have detected that year. It's stupid and it is a hoax, and I thought, and studied it is more than twice.
