Man we live on a very fragile planet, however the threat of a rogue planet interfering with our planet's orbit is the least of our problems as it is less likely than something more realistic like climate change.
Needless to say, if is "real" or not, there isn't much that can be done if such a thing was to come about. Regardless if this so called "evidence" holds any water at all, it seems it will be a "process" as the planet will come into view and go, and on it's passing it will mess everything up. If this is the case I say "whatever", and will deal with it *IF* it comes. In the meantime, I will worry about REAL doomsday threats like rapid environmental change, pandemic influenza, and nuclear annihilation.
Thanks for the post however, nice find. However this would make a better video game theme than something to take seriously. (At least for the time being, everyone should live life to it's fullest.)
