OK, there is the end of a 5000+ years cycles of one of the most complex and original calendars, and it is interesting to live that day (just as it was cool to live in the year 2000).
Everything else is complete fabrication and idiocy, assuming a coinciding "real world" scientific disaster "just because". And since nothing seems to really indicate that there will be disaster, let's cling to far-fetched theories like polar shifting, CERN and other worm holes...
I take the disaster in 3100BC was the Great Deluge...
