سکوت ترسناک: آیا ما در جهان تنها هستیم؟

On April 8, 1960, a young American astronomer, Frank Drake, turned a radio telescope toward the star Tau Ceti and listened for several hours to see if he could detect any artificial radio signals. With this modest start began a worldwide project of potentially momentous significance. Known as SETI - Search for Extraterrestrial Intelligence - it is an amalgam of science, technology, adventure, curiosity and a bold vision of humanity's destiny. Drake has said that SETI is really a search for ourselves - who we are and what our place might be in the grand cosmic scheme of things. Yet with one tantalizing exception, SETI has produced only negative results. After millions of hours spent eavesdropping on the cosmos astronomers have detected only the eerie sound of silence. What does that mean? Are we in fact alone in the vastness of the universe? Is ET out there, but not sending any messages our way? Might we be surrounded by messages we simply don't recognize? Is SETI a waste of time and money, or should we press ahead with new and more sensitive antennas? Or look somewhere else? And if a signal were to be received, what then? How would we - or even should we - respond? Paul Davies' The Eerie Silence: Searching For Ourselves in the Universe is an engaging and lucid guide to the 'Fermi Paradox' - why isn't the universe teeming with alien life? If aliens ever contact us, it will be the single most significant event in human history. And Paul Davies will be responsible for saying something back. For fifty years the Search for Extra-Terrestrial Intelligence has been scanning the skies. Now Davies, head of SETI's Post-Detection Task Group, with 'a rare talent for making physics mind-bogglingly vivid and exciting' ( Times Higher Education ), explores what the mysterious silence it has encountered could mean. Here he looks at exciting new ways to make contact with extra-terrestrial life. He considers what form advanced alien intelligence is likely to take if it exists. And more importantly, what exactly it would mean if it didn't ­- how extraordinary it would be if we were alone, to be human and here in this staggering, eerie silence... 'A magnificent cosmic tour of what might be out there in space' Sunday Times 'Rather wonderful' New Scientist 'Conveys excellently the fascination of the quest' The Times 'An authoritatively written, immensely clear, lay person's guide to the many things we don't know about the rest of the universe' Guardian Paul Davies is Director of the BEYOND Center for Fundamental Concepts in Science, and co-Director of the Cosmology Initiative, both at Arizona State University. An internationally-acclaimed physicist, writer and broadcaster, Davies is the author of some twenty award-winning books, including The Eerie Silence: Searching for Ourselves in the Universe, The Goldilocks Enigma: Why is the Universe Just Right for Life? and The Mind of God: Science and the Search for Ultimate Meaning . SETI - Search for Extraterrestrial Intelligence - is an amalgam of science, technology, adventure, curiosity and a bold vision of humanity's destiny. It is said that SETI is really a search for ourselves - who we are and what our place might be in the grand cosmic scheme of things. This title deals with SETI. "The Eerie Silence takes us on a journey through close encounters past and present, looks towards the future, and examines the foundations of carbon-based life on this planet to question whether we will ever find it anywhere else."--Jacket
