The Hitchhiker's Guide to the Galaxy by Douglas Adams answers the ultimate question of life, the universe, and everything with 42. In the story they calculated the answer with a supercomputer for 7.5 million years. Of course everyone was lost with the answer... 42? What do you mean by 42? Then they realised that the answer did not matter as much as the content of the question, and so they had to go on and create another even more powerful supercomputer to calculate for another few million years for the question. The supercomputer they built then was our planet Earth.
