A.2.9 Review of Wrinkles in Time George Smoot and Keay Davidson, Wrinkles in Time (New York: Avon, 1993),Pb, 331 pp. US$13.50/C$18.00 ISBN 0-360-72044-2 A.2.9.1 Review George Smoot worked on NASAs Cosmic Background Explorer (COBE) satellite, which proved the predictions of Inflation Theory, a refinement of the Big Bang Theory. The book was given to me by my son, David, for Christmas. To make a long story short, Inflation Theory was developed to explain why there were wrinkles in the space-time continuum. The question was what was it about the Big Bang that resulted in slightly non-uniform conditions, conditions which allowed for the creation of heavy elements (anything beyond helium) and galaxies, stars and planets. It also answered questions in the Big Bang theory which seem to suggest that somehow different parts of the universe had shared information at speeds faster than the speed of light. It turns out that this is because there was a period of hyper-inflation at the very beginning (before about 1 x 10^^-23 seconds). Space expanded (and continues to expand) at a speed faster than the speed of light, which doesnt contradict Einsteins dictum. Einstein said nothing *in* the universe could travel faster than the speed of light, but the universe isnt expanding in anything its space itself that is expanding faster than the speed of light. Anyway, its a very readable book the co-author, Keay Davidson, is the SF Chronicle science columnist. My judgement as to its reading level: Grade XII AP; or a mature person with some exposure to science. Not for the rank beginner, but speaks down a bit to people with university training in science. Thats why I gave it a Grade XII AP rating. Oh, also, its very out-of-date for those with considerable training or background in cosmology and particle physics. For people like that its an interesting history. For beginners its a good introduction to things like the Big Bang and Inflation Theory. A.2.9.2 Blurbs The scientific discovery of the century, if not all time Stephen Hawking [exaggerating a bit, imo] Behold the Handwriting of God Astrophysicist and adventurer George Smoot spent twenty years pursuing the holy grail of science a relentless hunt that led him from the rain forests of Brazil to the frozen wastes of Antarctica. For decades he persevered struggling against time, the elements, the forces of ignorance and bureaucratic insanity. And finally, on April 23, 1992, he made a startling announcement that would usher in a new scientific age. For George Smoot and his dedicated team ofBerkeley researchers had proven the unprovable uncovering, inarguably and for all time, the secrets of the creation of the Universe. Remarkabledeserves to be widely reada rewarding entrée to modern cosmology, a rare glimpse of important science in the making and a rollicking adventure yarn, all rolled into one, Wrinkles in Time breathes life and romance into science.
