Of course not. Planet X Nibiru is the place where the gods came from in Sumerian Mythology. If it were real, we would notice it because of the difference in planetary wobble, which basically means that if Nibiru were real, the planets would move differently. Besides, if the story were true, Nibiru would come back to Earth in 2012, and if it would, we would already be able to see it. Plus, why would a planet make such a big oval around the sun, it would only come to Earth every 3,600 years. Honestly people, see this nonsense through.
