Apocalypse know-how

What can Philosophy and Science tell about “Apocalypse”? The former seems to show a nihilistic power, while the latter uses a descriptive power, thus avoiding any religious or mystic impulse. The outcome, anyway, looks like a vade mecum. In any case, all “apocalyptic nouns” range between Prophecy and Foresight, Presage and Oracle, Superstition and Faith, Archetype and Destiny, Unconscious and Power, Messianism and Nowhere, Remorse and Day After, Society Game and Ceremony.
