The question stayed open

On 8 March 1978, BBC Radio 4 broadcast Fit the First of The Hitchhiker’s Guide to the Galaxy. It was a Thursday comedy in a slot that did not yet know it was founding furniture. In the fiction, Arthur Dent is a man whose house is about to be demolished for a bypass; the planet, shortly after, is demolished for a hyperspace express route. The only book that can help him is a Guide whose cover, in large friendly letters, says DON’T PANIC. The advice is typography. It is the first intelligible sentence a bewildered person is given. It is not a promise that Earth will be fine. In the story, Earth is not fine.

Later in the same invented universe a computer named Deep Thought spends seven and a half million years on the Ultimate Question of Life, the Universe, and Everything, and produces an Answer: 42. The Question has been lost. A later computer (Earth) is commissioned to find it, and is demolished before it can report. The joke is structural: an answer without a question, a guidebook whose first counsel is composure in a cosmos that will not be composed.

The radio series ran in 1978 and 1980. The novel arrived in 1979. Later travel (television, a film after his death, towels as costume, 42 as password) is not in the first broadcast. The first broadcast is a comedy with a typographic joke and, in due course, a number.

Adams was asked, for the rest of his life, why 42. Fan numerology arrived on schedule: binary tricks, base thirteen, monks. On 3 November 1993 he answered on the Usenet group alt.fan.douglas-adams. The answer, he said, was very simple. It was a joke. It had to be a number, an ordinary, smallish number, and he chose that one. He sat at his desk, stared into the garden, thought “42 will do,” and typed it. End of story. Binary representations, base thirteen, Tibetan monks: complete nonsense.

A later interview, recorded in 1998 with Iain Johnstone for BBC Radio 4 and not broadcast at the time, has Adams adding that 42 was the funniest of the numbers he considered. That is still a joke about tone, not a cipher. He declined hidden meanings for as long as people offered them.

The answer, and I should think that the Universe is now satisfied, is 42.Sense of Deep Thought’s report in the fiction. Wording follows the later novels more closely than any surviving 1978 cue sheet we have in hand; treat as literature, not a 1978 transcript.

DON’T PANIC and 42 share a universe. They are not synonyms. One is an instruction for the time in which you do not know. The other is an answer that cannot be used because the question is missing. Later readers made 42 a password and DON’T PANIC a greeting. Adams, asked to bless the metaphysics, declined.

In this constellation, 42 had already been treated as an aperture (a way of looking, not a verdict) in The Book of 42 and The Meaning of Life. Know With asked how we know. With Love asked how the heart has tried to speak. Stars, if it is live, follows the looking-up. This Guide asks a smaller, harder thing: what people actually do while the answer is not in hand. That last sentence is ours, dated 24 August 2026. It is not in the BBC’s 1978 billing.
