The world doesn't necessarily have to end with the sun exploding a millions of years from now.
A huge asteroid from out there could kiss the earth in 2020 for all we know.
A giant solar flare, rogue black holes, the reversal of the earth's magnetic fields and a zillion unforeseen events could turn out the lights whenever.
Damn, even an alien race could zap us with a superdooper ray gun us next week....this is unlikely but no one knows.
From the scenario in Cat's Cradle to Yellowstone Park, stories and speculations of the earth's destruction will always be with us.
