Welcome! “Alien Life” tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here’s today’s news:
g Message - Why wait for SETI to discover alien life? How about building your own radio telescope, hooking it your computer and searching the skies from your own backyard? See article.
g Imagining - Many problems faced the development of astrobiology as a credible science when it was first named in 1958. The most basic of these problems was skepticism on the part of many scientists of the time. The ideas of astrobiology touched too closely with science fiction to be considered seriously. The idea of life on Mars was definitely science fiction: H. G. Wells' "War of the Worlds" and Ray Bradbury's "The Martian Chronicles" attested to that. And Gregory Benford and David Brin in “Heart of the Comet” have since addressed the idea of life being seeded on Earth by comets. Why would anyone take these ideas seriously as science? See article.
g Aftermath - Book alert: The authentic discovery of extraterrestrial life would usher in a scientific revolution on par with Copernicus or Darwin, writes Paul Davies in “Are We Alone?: Philosophical Implications of the Discovery of Extraterrestrial Life.” Just as these ideas sparked religious and philosophical controversy when they were first offered, so would proof of life arising away from Earth. With this brief book (160 pages, including two appendices and an index), Davies tries to get ahead of the curve and begin to sort out the metaphysical mess before it happens. Many science fiction writers have preceded him, of course, but here the matter is plainly put. This is a very good introduction to a compelling subject. See article.
