Is Nibiru for real? Check it out.

Guys I have been seeing these videos on youtube about planet x / planet nibiru for quite sometime now but is any of this for real? I mean I am aware of the stuff they have been spraying in the sky for quite sometime now but I heard different theories about those. In this video it claims the reason for government to spray these so called "chemtrails" is to cover up planet x. See it for yourself and please comment and let me know what your take is on this? I am very curious as to what others think about this topic.
