apocalypse

n. revelation or vision of the end of the world (especially in Jewish and Christian writings)

Apocalypse (Greek: -translit. apoca'lipsis, literally: the lifting of the veil), is a term applied to the disclosure to certain privileged persons of something hidden from the majority of humankind. Today the term is often used to mean "End of planet Earth", which may be a shortening of the phrase apokalupsis eschaton which literally means "revelation at the end of the world".
