42 (the Answer to the Ultimate Question of Life, the Universe, and Everything)

The number 42 is famously known as "the Answer to the Ultimate Question of Life, the Universe, and Everything" from Douglas Adams' science fiction series, "The Hitchhiker's Guide to the Galaxy." In the story, a group of hyper-intelligent beings builds a supercomputer, Deep Thought, to find the meaning of life. After seven and a half million years of computation, the computer reveals that the answer is simply 42, but the actual "Ultimate Question" remains unknown. This concept humorously highlights the complexities and absurdities of seeking definitive answers to profound existential questions.
