  1. Question

    why does the Mayan calender say the world will end in 2012?i know you have answered the plant x question....however i have heard that they have been pretty accurate in the past with other planetary stuff ,did they use planets so much to date things? and does that make them better at understanding the solar system? so if they have predicted an end in 2012 will it happen ,how can you be sure you know more than they did?

    Calendars exist for keeping track of the passage of time, not for predicting the future. The Mayan astronomers were clever, and they developed a very complex calendar. Ancient calendars are interesting to historians, but of course they cannot match the ability we have today to keep track of time, or the precision of the calendars currently in use. The main point, however, is that calendars, whether contemporary or ancient, cannot predict the future of our planet or warn of any bad things to happen on a specific date such as 2012.
