In cogent and entertaining language, astrophysicist and popular writer Bennett (On the Cosmic Horizon
) explains that the determining factor in whether we can locate intelligent life elsewhere in the universe is whether such a civilization—and our own—can continue long enough to develop the highly sophisticated technology needed for interstellar travel. If humans are going to meet that challenge, Bennett argues, we must solve “global warming, debilitating disease, terrorism, poverty, and war. We must use our compassion to teach all people to respect all others, regardless of their ethnicity, religion, or gender.” This political message is couched in fascinating and completely accessible science. Bennett does a wonderful job of explaining the conditions necessary for simple life, how we might discern its existence and where we should be looking. He then does the same thing for intelligent life. While he is fair to those who believe life is incredibly rare, he makes a compelling case that life is likely to be abundant. He also predicts that we will gather incontrovertible proof of intelligent life in the universe within the next 20 to 30 years. 8 color, 30 b&w illus. (Mar.)
