I am not able to discern whether this has any validity at all - someone from the Earth Changes & Pole Shift site posted an apparently well-thought-out explanation of the path of "Planet X" complete with diagrams.
(BTW I used to be impressed by photos taken through a red filter,as advised on that site, until I took some myself. . . .& also found what they refer to as "moon swirls" around local street lamps.. . .)
Anyway, here is the link: http://poleshift.ning.com/profiles/b...planet-x-ver-5
