What Leads Up to the Ending
Arthur is rescued from Earth's demolition by his friend Ford Prefect, an alien researcher for The Hitchhiker's Guide to the Galaxy. They end up aboard the stolen starship Heart of Gold with Zaphod Beeblebrox, the two-headed President of the Galaxy, Trillian and Marvin, a depressed robot. They land on the legendary planet Magrathea, where custom planets were once built.
What Happens at the End of The Hitchhiker's Guide to the Galaxy
The planet designer Slartibartfast explains that a supercomputer, Deep Thought, calculated that the Answer to Life, the Universe and Everything is 42. Since no one knew the question, an even bigger computer was built to find it: the Earth. The mice, who are hyper-intelligent beings, ran the experiment. Earth was destroyed just before it finished. The mice offer to buy Arthur's brain, since it might hold the question. Arthur refuses, and the group escapes after a fight with police. Arthur's subconscious offers a question: “What do you get if you multiply six by nine?”

Who Will Like This Ending
Readers who enjoy endings that are absurd and funny will find a lot to talk about here. If you prefer every thread tied up neatly, it helps to know in advance how Douglas Adams closes the story, which is exactly why many readers look it up. Either way, the final chapters reward a second look once you know where everything is heading, because small details from the middle of the book start to matter.

Discussion Questions About the Ending
If you are reading The Hitchhiker's Guide to the Galaxy with a book club or a friend, these questions work well once everyone has finished:
- Did the ending surprise you, or had you seen it coming from the first chapters?
- What does the final scene say about meaning, and do you agree with Douglas Adams's view?
- Which character made the most important choice in the last part of the book, and was it the right one?
- How would the story feel if it had ended one chapter earlier or one chapter later?
- Does the ending leave you hopeful about the characters, or do you worry about what comes next?
- Would you describe the ending as absurd and funny, or would you choose a different word?
How to Read the Final Chapters Again
- Compare the opening with the close. Look at how the first chapter introduces meaning and how the ending answers it.
- Track each final choice. The table above shows where every main character ends up, so ask which of those outcomes was earned.
- Notice what Douglas Adams leaves unsaid. Gaps in the last pages are often deliberate, and they are where most of the debate about the ending begins.
- Listen for echoes. Images, phrases or settings from earlier in The Hitchhiker's Guide to the Galaxy often return in the final scene with a new meaning.
Questions to Ask Yourself After Finishing
- Was the ending of The Hitchhiker's Guide to the Galaxy earned by what came before it, or did it feel sudden?
