Lol?
The overall concept of anything other than a calendar ending on 2012 is just too ridiculous to even think about considering, but I'll look at it from all views.
Every calendar must end some day. Go look at your calendars, if you have one. I can bet you $50 egold, or paypal, that your calendar ends.
Does that mean that our 2ND world will be ended on that day!!??!
It's completely inconceivable to me as to how most of you even thought up such. Those scientist never met the mayans! I'd hate to say that they're just making this up, as a ploy to LOOK like they're doing something, but come on ..
Not only are they, and most of you, saying that the Mayans were future-tellers, or time-predictors, but you're not giving them enough credit, in some stances. It's just an ended calendar.
Go to wallmart, and get some wood, glue, and rope. Go to the nearest forest with a large gap in it from one side to the other.
Build a bridge, and get over it.
