# The Hitchhiker's Guide to the Galaxy

Arthur Dent's Thursday begins badly when bulldozers arrive to demolish his house for a bypass. It gets worse when his friend Ford Prefect reveals himself to be an alien researcher who has spent fifteen years stranded on Earth, and the Vogon Constructor Fleet arrives to demolish the entire planet—also for a bypass. Ford rescues Arthur by hitching a ride on a Vogon ship moments before Earth's destruction.

Thus begins Arthur's reluctant journey through a universe that proves just as absurd, bureaucratic, and hostile as the institutions he knew on Earth. He and Ford are ejected from the Vogon ship after enduring Vogon poetry (the third worst in the universe) and improbably rescued by the starship Heart of Gold, stolen by Zaphod Beeblebrox—two-headed, three-armed ex-President of the Galaxy—along with Trillian (the one woman Arthur ever fancied at a party) and Marvin the Paranoid Android.

The Heart of Gold's Infinite Improbability Drive has led them to a legendary planet: Magrathea, where custom planets were once manufactured for the ultra-rich. There, Arthur learns that Earth was itself a computer, commissioned by another computer (Deep Thought) to find the Question to the Ultimate Answer. Deep Thought had previously computed that the Answer to Life, the Universe, and Everything is 42, but no one knew what question produced this answer. Earth was destroyed five minutes before completing its ten-million-year calculation.

The series continues through four more novels, following Arthur's attempts to find meaning in a meaningless universe. He discovers that the Question, derived from his own brainwaves, may be 'What do you get if you multiply six by nine?'—suggesting cosmic error or joke. He falls in love, loses her, finds her again. He becomes a sandwich-maker on a primitive planet. He dies several times in different timelines. Marvin outlives everyone and everything, remaining depressed throughout.

Adams uses science fiction conventions to satirize everything from digital watches to philosophy to the publishing industry. The Hitchhiker's Guide itself—a book containing all knowledge, with the words 'DON'T PANIC' on its cover—parodies encyclopedic authority while embodying it. The humor is distinctively British: deadpan, absurdist, finding comedy in bureaucracy, inconvenience, and the gap between cosmic significance and human pettiness.
