You're asking me to pick my favorite, out of all the possible ways the
world could end?
hooo. Tough choice.
I've always been fond of the "grey goo" nano-technology destroys the
world idea...
And I really like the "a comet strikes Earth and pulzerizes everything
then causes eternal ice age" idea...
And nuclear winter is pretty cool.
But I think the best way to go would be in a sudden "Super-Nova" of our
sun... you know, some scientist sends some weird thing into the sun and
it causes a massive explosion... Earth burned up less than 8 seconds
later. The glory!

or perhaps the "high energy physics bubble universe destroyer" idea is
the one to pick.
or maybe the "cascading environmental disasters" is the way to go
or maybe space aliens, like the Borg...
or perhaps "the Kingdom of God" is really at hand, after 2000 years!
or mabye a new killer disease will be discovered (or created!) and wipe
out all life
or
well, you get the point!
