There are some 2012 sites with links to numerous prophecies and lore from different cultures (Sumerian, Mayan, Hopi, Inca, Dogon, Biblical, etc)
Some seem pretty fanciful.
If the ancient predictions of planet changes affected by a solar event or solar system event caused by the orbit of another planet(s), binary system, and/or accompanying comet/asteroid bodies - destined to transect ours every 3600 years or so have any validity - we should know in several years.
For sure everything in the outer solar system seems to be warming up and no one seems to have figured out a reason why.
Here are a few sites- you can do more searches on some of the terms. Don’t be offput by the name “Nibiru”- that is just one name of many given to the planet X theory. Another is “eris”
