Well, it would make sense. I'm a firm believer in planet X and if it is real, I'm sure that the major governments of the world would not want it to attract global media attention because it would cause mass hystaria. One other interesting thing is that recently, there have been increasing purtibations (yes I'm quoting the movie) on our planet. More wars, unusualy harsh droughts, odd flooding, and whole manners of other human and biological anomalies.
