Nostradamus predicted that the Third World War would start with a conflict between major world powers. He also said that it would involve nuclear weapons and would be super destructive. But, don't worry, he also said that humans would survive - so, there's that.

But, despite the vagueness, people have been trying to interpret them for centuries - and it's still a major topic of discussion today.
