The Search for Extraterrestrials: Intercepting Alien Signalsby Monte Ross
Synopses & Reviews
In The Search for Extraterrestrials, Monte Ross explores in detail the key problems in starting a search, the programs that have failed and those that continue. He includes the fundamental considerations and the physics of the necessary laser, UV, IR and RF technologies, as well as coding and information theory considerations.
The author explores future possibilities providing the reader with a comprehensive view of the many ways signals from aliens could be sent and explains why the search using RF leaves more than 99% of the electromagnetic spectrum unexamined. He also demonstrates the many parts of the electromagnetic spectrum, considering the next likely steps in this unique enterprise. Given man's intrinsic nature to explore, the search will continue in one form or many, until success is achieved, which may be tomorrow or a millennium away.
In summary, Monte Ross proposes to get around the failure of a fruitless search at radio frequencies by developing, in a precise way, the argument for searching for transmissions in the optical region of the electromagnetic spectrum.
Explore the challenges in searching for evidence of extraterrestrials. The book is the first to examine electromagnetic frequencies besides RF and microwave as signal sources, taking into consideration all the ways that extraterrestrials might communicate.
Follow Monte Ross of the Laser Space Signal Observatory as he explores the challenges in searching for evidence of extraterrestrials, the programs that have failed, and those that continue. The book circumvents the failure of searches at radio frequencies by being the first to explore electromagnetic frequencies besides RF and microwave as possible signal sources, taking into consideration all the ways that extraterrestrials might try to communicate with us. Throughout the presentation, all the ideas, concepts, and approaches are explained clearly, without the use of complex math or physics.
