Answer to Life, the Universe, and Everything

What is the answer to life the Universe, and Everything?
The answer to ‘life, the universe, and everything’ of course, is 42. So says Douglas Adams in The Hitch-hiker’s Guide to the Galaxy.

"simple answer" to The Ultimate Question is requested from the computer Deep Thought—specially built for this purpose. It takes Deep Thought 7½ million years to compute and check the answer which turns out to be 42.

According to The Hitchhiker's Guide to the Galaxy, a race of vast hyper-intelligent, pan-dimensional beings constructed the second greatest computer in all of time and space, Deep Thought, to calculate The Ultimate Answer to The Great Question of Life, the Universe, and Everything. Distracted by a demarcation dispute with two philosophers, a "simple answer" is requested. After seven and a half million years of computing cycles, Deep Thought's answer is: forty two.
“ "I think the problem is that the question was too broadly based..."

"Forty two?!" yelled Loonquawl. "Is that all you've got to show for seven and a half million years' work?"

"I checked it very thoroughly," said the computer, "and that quite definitely is the answer. I think the problem, to be quite honest with you, is that you've never actually known what the question is."
