The book begins by introducing electromagnetic radiation and its behavior in space and progresses toward understanding pulsars and fast radio bursts. It then shifts to the development of algorithms to sift through cosmic noise, seeking patterns indicative of intelligent life. Cosmic Signals uniquely balances the scientific rigor of SETI with the recognition of broader implications, providing a comprehensive understanding of the field.
The practical implications include advancements in signal processing, radio astronomy, and a deeper understanding of the cosmos.
