To expand on what others have said, in the Hitchhikers Guide to the Galaxy story an ancient alien civilisation create a massive computer called Deep Thought and ask it "What is the meaning of life, the universe and everything"

From the book:

"Good Morning," said Deep Thought at last.

"Er..good morning, O Deep Thought" said Loonquawl nervously, "do you have...er, that is..."

"An Answer for you?" interrupted Deep Thought majestically. "Yes, I have."

The two men shivered with expectancy. Their waiting had not been in vain.

"There really is one?" breathed Phouchg.

"There really is one," confirmed Deep Thought.

"To Everything? To the great Question of Life, the Universe and everything?"

"Yes."

Both of the men had been trained for this moment, their lives had been a preparation for it, they had been selected at birth as those who would witness the answer, but even so they found themselves gasping and squirming like excited children.

"And you're ready to give it to us?" urged Loonsuawl.

"I am."

"Now?"

"Now," said Deep Thought.

They both licked their dry lips.

"Though I don't think," added Deep Thought. "that you're going to like it."

"Doesn't matter!" said Phouchg. "We must know it! Now!"

"Now?" inquired Deep Thought.

"Yes! Now..."

"All right," said the computer, and settled into silence again. The two men fidgeted. The tension was unbearable.
"You're really not going to like it," observed Deep Thought.

"Tell us!"

"All right," said Deep Thought. "The Answer to the Great Question..."

"Yes..!"

"Of Life, the Universe and Everything..." said Deep Thought.

"Yes...!"

"Is..." said Deep Thought, and paused.

"Yes...!"

"Is..."

"Yes...!!!...?"

"Forty-two," said Deep Thought, with infinite majesty and calm.”

&gt; The answer to this is very simple. It was a joke. It had to be a number, an ordinary, smallish number, and I chose that one. Binary representations, base thirteen, Tibetan monks are all complete nonsense. I sat at my desk, stared into the garden and thought '42 will do' I typed it out. End of story.
