When did Nostradamus predict that the world will end?
Nostradamus didn’t actually predict anything specific – his quatrains are so vague that they are not predictions so much as abstract ramblings. Different people have interpreted his writings differently, and no two agree on what he predicted. The only accurate predictions are “interpretations” made AFTER the events that occured – no prediction was made BEFORE the event (funny how that works). The only scientific evidence about the end of the world is that in about 3 billion years the sun will expand to a red giant and broil the Earth. Why we exist is a philosophical question, not a scientific one.
