Eschatology

From the SL4 Lexicon:

eschatology:

Study of the end of the universe, or the end of human civilization, depending on which definition you're using. Sometimes, but not always, used in the context of religion. Although the word isn't used explicitly, many Singularity analysts are implicitly studying the "eschatology" of "human-only" civilization. Meanwhile, cosmologists such as Frank Tipler and Stephen Hawking are studying the eschatology of the universe.
