The Technologies in the Search for Extraterrestrial Intelligence: Listening to the Cosmos - Softcover

Inhaltsangabe

Every science has its defining moments of apparent breakthrough — the results that set the instrument readings racing, that bring researchers running down corridors, that press the imagination hard against the boundaries of what is possible. SETI is no exception.

In the decades since systematic searches began, there have been anomalies, surprises, and candidates that, for hours or days or weeks, could not be dismissed. None has yet crossed the threshold of confirmation. But their stories are not stories of failure. They are stories of a discipline learning, with great discipline, how to be honest with itself.

This book examines that record. It begins with the one signal that has never been explained — the Wow! signal of 1977, which remains, nearly five decades after it was recorded, the single most compelling candidate in the history of the search. But despite the excitement of Wow! . It did not repeat or since.

It then widens into a systematic survey of every significant candidate and false alarm, from the pulsars mistaken for civilisations in 1967 to the James Webb atmospheric anomalies of 2023.

And it closes with a hard look at why verification is so difficult — at the sociology and psychology of a field in which the stakes are so high that even careful scientists occasionally allow hope to run ahead of evidence.

The most important question we have ever asked is still open. The instruments are still listening. And the silence, for now, is not an answer.

It is an invitation.
