The meaning of life; In an episode of Douglas Adams in The Hitchhiker's Guide to the Galaxy, a race that is intelligent, poses this question to a super-powerful all-knowing computer.
What is the meaning of the universe and life? They ask.
The super powerful computer announces that it will say 7.5 million years later for the final answer, saying I need to think a bit. This clever race will not forget the subject even after 7.5 million years. Preparations and feasts are made to hear the final answer.
The squares are filled with millions of people.
Finally, the supercomputer says you will not like this answer at all; and the answer is 42.
