Loonquawl and Phouchg are not happy with that answer. Deep Thought explains to them that they just never really knew what the question was.
So Deep Thought will design a computer that will come up with the question for them. It will be a giant computer, the size of a planet. And it will be so complex that organic life will be part of its hardware. And it will take 10 million years to figure out the question.
According to Deep Thought, Loonquawl and Phouchg will go down onto the planet to monitor its operation.
Deep Thought names this planet the Earth, which Phouchg thinks is a dull name.
But that explains a lot about how the world works—like how you'll always be in the slowest lane if you're driving or the slowest line if you're at the grocery store. It's all part of the program.
