+ D'après https://simple.wikipedia.org/wiki/42_(answer)
+
+ 42 is the "Answer to the Ultimate Question of Life, the
+ Universe, and Everything" in The
+ Hitchhiker's Guide to the Galaxy books. It was computed by Deep Thought, the second greatest
+ computer ever. The descendants of Deep Thought's creators are upset by the numeric nature of the
+ answer, not understanding what to do with it or what to tell the people who had commissioned the
+ 7.5-million year project.
+
+ When asked to produce The Ultimate Question to go
+ with the answer "42", Deep Thought admits it
+ is
+ not capable of computing that itself, but that it can help to design an even more powerful
+ computer,
+ which can. This new computer will incorporate living beings into the "computational matrix" and
+ will
+ run for ten million years. It is the planet Earth.
