Life, the Universe, & Everything: The Marion K. "Doc" Smith Symposium on Science Fiction and Fantasy is an academic conference held annually since 1983 in Provo, Utah. It is the longest-running science fiction and fantasy convention in Utah, and one of the largest and longest-running academic science fiction conferences. An annual proceedings volume, Deep Thoughts (named after the computer Deep Thought from The Hitchhiker's Guide to the Galaxy), publishes the academic papers and main addresses given at the event. The symposium was named, jokingly, after the Douglas Adams novel Life, the Universe and Everything.
