内容説明
Scientists have been searching for signals from extraterrestrial civilizations since Frank Drake's first radio survey in 1960. But what would actually happen if SETI's search succeeds? Is there any way we could even make sense of the signal we receive?
Written by an expert in communication systems and translation technology, this book explores the science of interstellar communication. It explains how this process may unfold, how an ET communication link would work, the types of information it could convey and how professionals, amateurs and ordinary people like you would participate in the effort to understand what another civilization has to say.
Along the way, the book introduces readers to many aspects of modern-day communication systems and computing. Featured as well are dozens of illustrations, photos and real-world examples, rounding out this compelling foray into the mechanics of interstellar communication.
"Scientists, policy makers, and all interested in the likely future discovery of alien life will want to read this book."
- Steven J. Dick, Former NASA Chief Historian
