A rogue planet named Nibiru that passes by the earth once every 3,657 years is about to pass by within 5 years and will cause the poles to shift. The North Pole will become the South Pole etc... It wont lead to the end of the world, but will lead to the end of civilization.
How do I know this? Because it's covered in zetatalk.com, alienshift.com, and phils.com.
Don't say you haven't been warned.
