#9. Nuclear War
Terrifying, because if it was happening in every part of the world, there’d be no hope of survival. If the sun blows up or there’s a black hole, we all die in a millisecond, painlessly, and that’s the end of that. With a different type of war or zombies, lots of people would die, but there would still be hope for survival. With a nuclear war, it would be impossible to survive. You could not avoid a nuclear blast. Even if you did, you would end up dying a slow painful death from radiation poisoning, which you would get very quickly. You would be on your deathbed for years, not even able to fight from being so sick. If there was an all-out nuclear war where every country was involved, we’d all be in for a horrible fate.
