It may or may not be true, but spending time with this kind of material is a waste of time. You won't know if any of it is true unless it happens. I have found that there is reasons to believe that the Mayan calendar stops at Dec. 2012 and I've found some "Christian" writings that seem to support that idea. But even if I'm right, so what? Won't know that until it happens. The time is better spent keeping God's commandments rather than speculating about an event that may or may not happen.
