He doesn't mean there is no chance of a tenth planet, he means that there is no Nibiru - the planet with the exotic orbit that many f**king idiots, sorry, people believe is going to encounter Earth within the next year because it was on an episode of Dark Skies, which was cancelled and is therefore a conspiracy of truth.
Also when he says the pole doesn't flip, it migrates - I think he just means to say it isn't a sudden change, it takes a while. Which is true.
I wouldn't expect a reply from DocBill himself... you'll be waiting a while.
