Sir Martin Rees is Royal Society Research Professor at Cambridge University & Astronomer Royal.
Science writer and astronomer Rees summarizes the history of the universe, pointing out that six numbers related to basic physical constants (for example, the relative strengths of the gravitational and electromagnetic attraction) determine how the universe developed. In addition, he shows how, if these numbers were only slightly different, stars and galaxies would not form, complex chemistry would not be possible, and life could not evolve. This raises the interesting philosophical question, Why? One could dismiss the question by saying that, if it were otherwise, we wouldn't be here to ask or that there is some underlying theory as yet unknown that would show that these values must be what they are. However, Rees suggests that these numbers were set shortly after the big bang and could well have been different. Indeed, there may be a multitude of other universes, forever inaccessible to us, in which they are different. Thus, with a huge choice of possible universes, one must exist that could support intelligent beings who can observe and question. Whether one agrees or not with Rees's ideas, his book is recommended for its cogent synopsis of modern cosmologic thought. [BOMC alternate selection.]--Harold D.
