a whimper or a bang?

just wondering how the world will end. will it be an astroid smashing us to smithereens? [quite possible] or perhaps a foolish human error, somebody pressing a button followed by alot of people pressing buttons [equally possible] or maybe we''ll just keep on reproducing until we exhaust all of our natural resources and slowly peter out as a race. the mayans, a long gone people actually predicted a date for our demise. december 21st, 2012. that was the last day of their calender. maybe the guy who made the calendar just didn't go to work the next day and it slipped his mind. this little planet of ours has a strange and violent history. how it manages to keep its orbit, so precise, so in tune with everything else out there is truly miraculous. i'm not sure whats in store, i think smarter folks than me have studied long and hard and their guess is as good as the next person's. anybody out there want to throw their hat into the ring? me, i''ll just keep on spinning with the rest of you and hope gravity's hold on us lasts for awhile longer....jc
