The Hitchhiker's Guide to the Galaxy is about everything in life and the universe. In the books, the "answer" is 42, but the question is unknown. To discover the question, a giant computer called Earth was built. Although it seems silly, perhaps Douglas Adams was correct. Maybe not just earth, but the whole universe, is an incredibility complex computational system, processing the answer to some unknown question. The universe is made of information, similar to a computer, and physics certainly is based on computational principles. But, is it running some grand program?
