Un livre scientifique très crédible, qui vous fait porter un regard plus critique sur la science-fiction, ou comment la réalité ne rejoindra probablement jamais la science-fiction. C'est un livre sérieux, du très bon travail.

I learned about this book watching the History Channel’s multi-part documentary about the creation of the Earth and the amazing journey it has been on ever since. The book covers the same story but in greater detail, with particular emphasis on the origin of life and the equally amazing journey it has been on, from basic microbial life to complex animal life to highly intelligent life capable of conscious thought—to homo sapiens, us. Are we really the stuff of stars, as Carl Sagan said? Ho [...]

The theory posited in "Rare Earth" has extraordinary implications, so extraordinary that I ended up reading the book twice. Essentially, the authors, both scientists, contend that due to the unique manner in which the earth was formed and the distinctiveness of its composition, it may be one of a rare few planets, or perhaps the only planet, inhabited by intelligent animal life within our galaxy or even other galaxies.We know that every day new planets are being discovered and many of them exis [...]

What a tome. every imaginable unlikely event that had to chronologically occur to create multicellular life on Earth. Concieved as a rebuttal to "the Drake Equation" Carl Sagan made famous, this is an easily accessible brilliant scientific re-evaluation of the possible path of life in our universe, so conscientiously presented that this book is cited by the Creationist community as an argument FOR Intelligent Design. To paraphrase quantum physics; "whatever can happen, will happen". Bring on the [...]
