I was watching some TV show and they made some interesting points.
The Mayan calendar, which has accuately predicted many of the worlds events, sudden stops on December 21, 2012. Another man created some for of graph which in a way charts time. His graph also feel off the charts of the exact same date.
They came up with a theory which sounds good to me. Since time is linear, you go from Monday to Sunday every week, it would be impossible for a calendar to end or for a graph of a cycle to sudden dip of the charts. These people claimed that on December 21, 2012, one of two things could possibly happen.
1) The end of humanity and the earth for that matter.
or
2) Humans will discover how to compression time and learn the ability of time traveling. This would explain the reason for the graph to sudden stop or a calendar to stop. Time would no longer be linear.
