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 to 20.

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.

The complete list:

1. Asteroid impact
2. Gamma-ray burst
3. Collapse of the vacuum
4. Rogue black holes
5. Giant solar flares Solar flares
6. Reversal of Earth's magnetic field
7. Flood-basalt volcanism
8. Global epidemics
9. Global warming
10. Ecosystem collapse
11. Biotech disaster
12. Particle accelerator mishap
13. Nanotechnology disaster
14. Environmental toxins
15. Global war
16. Robots take over
17. Mass insanity
18. Alien invasion
19. Divine intervention
20. Someone wakes up and realizes it was all a dream
