True end of the World.

It is already December 22 and the world did not end as predicted by the Mayan calendar.  I deep down did not believe it but I did joke about it.  Many in history has predicted the end of the world.  Many are mostly religious charlatans but one other prediction that resonated with many was the Y2K one.  It was said that when the calendar hit the year 2000,  world wide chaos was to happen.  Partly because the global computerize system would not know what to do after the date 12-31-99.  Other Christian zealot also said Christ was coming back and that will mark the Biblical prediction of the end of the world.  Like this  Mayan calendar doomsday prediction, the Y2K one was also a hogwash!  As far as I am concern, the only true science base prediction that I believe is the death of the Sun as a Red Giant.  The scientific community believes that in roughly 7.6 billion years from now, the Sun will ran out of Hydrogen to fuse as Helium and it will slowly grow into a Red Giant.  By then the Sun will be so big that it will engulf the Earth.   The Earth will be toasted away.  That I believe.
