Answer to Life, the Universe, and Everything

The Answer to The Ultimate Question Of Life, the Universe and Everything was announced by Douglas Adams in his science fiction series The Hitchhiker's Guide to the Galaxy. In the story, the Ultimate Answer to Life, the Universe, and Everything is sought using the supermegacomputer Deep Thought, however the computer was insufficiently powerful to provide the Ultimate Question when asked after it had produced the Answer (after a very long computation time - 7.5 million years). The answer given by Deep Thought prompted the protagonists to embark on a quest to discover the Question to which this is the Answer.
