What are the implications for Humankind of alien civilizations that may be "out there?" In thinking about contact with extraterrestrials, we have to grapple with a host of philosophical, religious, and societal questions. The biggest is whether the outcome of contact will be beneficial or harmful. Will contact uplift us, bringing a golden age of wisdom and prosperity? Or will it demoralize, even destroy us? This thought-provoking book presents a rainbow of opinions expressed by scientists, sociologists, historians, legal and political thinkers, and many others. The author takes into account not only scientific speculation, but also fiction and popular opinion. He challenges the most frequent assumptions that unerlie our thinking. He looks at both sides of the "where are they" debate, questioning the alleged paradox and proposing new ways of thinking about the issue. The serious practical questions raised by extraterrestrial intelligence are becoming harder to avoid as our search technologies and methods improve, as we identify ever-greater numbers of planets orbiting other stars, and as the wave front of our radio, television, and radar signals reaches out into the Galaxy. How should we deal with contact if it happens? What do we want to say to an extraterrestrial civilization? Will we speak as one, or as many? What should we do if we find alien technology in our solar system? Should we simply be watchers and listeners, or should we actively seek contact by sending out messages proclaiming our presence? Our answers reveal our hopes and our fears.

The proper study of mankind is not merely Man, but Intelligence. 1 -Arthur C. Clarke, 1951 In the long-running television series "e;The X-Files,"e; the original Deep Throat said to FBI Special Agent Mulder that "e;there are those like yourself who believe in the existence of extraterrestrial life."e; Ah, but that's not the question. If extraterrestrial life exists, most of it may be in simpler forms comparable to the one-celled organisms of Earth biology. Finding such life would be fascinating for scientists, but may be of only passing interest to the general public. What intrigues the average citizen is the possibility of contact with extraterrestrial intelligence. We want to communicate with other sentient beings, learning what they know and telling them about ourselves. We want to ? nd out how they are like us and how they are different. Microorganisms don't have a lot to say. There is another implication of contact that underlies this book: Intel- gent extraterrestrials might have an impact on our future. The information they send us-if any-might change our cultures. They could have c- scious intentions toward us, and possibly the technologies to reach us directly. Their intentions may be benign-or not. Our interest in alien minds is not new. The idea that intelligent beings exist beyond the Earth has been part of the Western intellectual tradition for more than 2000 years. Sometimes this belief was widespread; at other times, it was out of fashion.

"The Drake Equation, Take Three (p. 162-163)

The Drake equation was derived from an assumed mode of contact: the detection of electromagnetic signals from very distant stars. It rested on the assumption that technological civilizations do not expand beyond their home systems. The density of such civilizations was determined by the number of separate evolutions to life and intelligence. The equation did not take into account the possibility of interstellar exploration, interstellar colonization, and direct contact.

That gap has been challenged forcefully. The Drake equation is wrong, Dyson argued, because it says that the number of extraterrestrial civilizations is equal to the number of independently originating civilizations. In fact, life spreads, diversi? es, and speciates. Any community of intelligent creatures adapted to living freely in the vacuum of space will spread and speciate in the Galaxy. One intelligent species let loose in space may become a million intelligent species within an astronomically short time.

Consequently, the Drake equation gives only a lower bound to the number of civilized societies.1 Shostak and Barnett, while defending conventional SETI, acknowledged that one star system could seed others if interstellar travel happens. The number of technological societies might be large even if the chance of evolving intelligence at one particular location is small.2 David Viewing of the British Interplanetary Society proposed a revised Drake equation in 1975, introducing factors representing the average number of colonies established by each independent civilization, and colonies established by the colonies.

Brin argued later that the equation needs three new factors when we introduce star travel: V—the velocity at which an interstellar culture grows into space, pausing to settle likely solar systems and rebuild necessary industry before again continuing its expansion L(z)—the lifetime of a zone of colonization into which a species has expanded, after which the settled region becomes fallow again A—an approach/avoidance factor, different for each culture, representing a “crosssection” for discovery by contemporary human civilization. This encompasses motivations to initiate or avoid contact, life-style variations, abandonment of radio for other technologies, and anything else that might cause an extraterrerstrial culture to be more or less observable.

At a minimum, the equation should include a factor for the probability that another technological civilization would engage in interstellar exploration, expansion, or colonization. This could have powerful implications. The factors in the traditional equation can be seen as ? lters that reduce the probability of contact with technological civilizations. Adding an expansion and colonization factor could greatly increase that probability by expanding the range of locations where technological societies may exist. Those most devoted to the classic SETI paradigm continue to resist including interstellar expansion in their calculations. One can see why; opening the door to a direct encounter raises the question of why we have not seen evidence of alien technology nearby. The direct contact scenario also has signi? cant implications for the possible consequences."
