The possibility that humans are not alone in the Universe is one of the most intriguing unanswered questions for mankind. Distant Encounters provides a discussion of the scientific and technical implications, including possible faster-than-light space travel and radio communication, as well as the philosophical and religious ones of extraterrestrial intelligent life. It gives a summary of the chemical and biological evolution of the Universe to demonstrate, as a counterbalance to the ‘rare earth’ theory, why intelligent life might exist somewhere else in the Universe, apart from on Earth.
