Discover Magazine has developed a list of 20 potential ways
the world could end. Some of them are pretty cool. Others
are Sci-Fi clichés. They obvious had to stretch to make it
I'm not buying #3 (Vacuum Collapse) or #5 (Magnetic Field Failure). #18 (Alien
Invasion) has some promise... but space is pretty big, so those Damn Ay-leens
are probably pretty far away and not very interested in us. Personally, if I
had my choice, I take #20... but that's just me.
