Hi there,
admittedly, I'm very sceptic about this. I have never seen anything that even comes close to a serious hint at these "facts", not to talk of proof. For instance, that whole Nibiru-matter is a laugh. Have you seen the alleged Nibiru-photos that this sect around Nancy <whatever her family name was>? These were so very embarrassingly bad...
Sorry I can't say much good about these convictions, but I see it from a fact-based point of view, and under that gaze the X-facts last as long as a single snowflake in Muspel. They do make an entertaining science-fiction reading, though - but that's about everything good you can say on that topic.
Cheers!
Markus
