Description and Table of Contents
Description
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.
