Riassunto

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.

Recensione:

From the reviews: “Ross begins by reviewing the vast distances involved in a search, such as the density of stars in space and how long it takes light to travel to Earth. ... Copious illustrations are very helpful in facilitating an understanding of many of the technical details. Ross has produced a well-organized ... book that covers the basics of SETI very well. Summing Up: Recommended. Lower- and upper-division undergraduates and general readers.” (M.-K. Hemenway, Choice, Vol. 47 (10), June, 2010)
