Idiocy. Pure idocy.
The Mayans have a calendar cycle, just as we do. Do we freak out every time a year ends? No. We have a party because we know a new year starts the next day. We know this will happen whether we bought the 2013 calendar or not. It doesn’t have to be stuck to the wall for the next year to exist.
The same is true of the Mayan calendar. Whether or not they made a new calendar, the next cycle will start as soon as the old one ends. The lack of a new calendar does not cause time and space to end.
This must be the twentieth question on this that I’ve answered on fluther. Does no one read the other questions or answers? Why do I even bother? I should cut and paste.
