The Mayans were exellent mathematicians. Their ability to study the stars trajectories and calculate that all these planets are going to line up tommorrow was incredible. But as far as I have seen, no where did they say this was going to be the end of the world. But this was the end of their calender . So maybe it was merely time to  study the trajectories after they line up and re calibrate their calender. But the end of the world does make for better TV. GLTA. SS
