We have seen some of the prophecies come true, such as the quatrains about the different anti-Christ. I say different anti-Christ because it appears that Nostradamus indicates more than one. The third anti-Christ very soon annihilated. 27 years his bloody war will last. The heretics are dead, captives, exiled blood soaked human bodies, water and a reddened icy rain covering the entire earth.
More information is to be accessed to be fact or fiction by the occurrences.
Anyway, the way the Nostradamus sees the world ending is not conventional. He says that the earth will be flooded and that meteors will hint the earth. However the human race with survive because he says that we would have colonies space by the time that this happens. And it shall last so long that everything will perish except the dry earth itself and the human race. Before and after these floods many nations shall see no rains and there will fall from the sky such a great amount of fire and meteors that nothing will remain unconsumed.
