Smoot's book chronicles the excitement, frustrations, and adventure of the work of science, focusing on his careful efforts and eventual triumph with the COBE (Cosmic Background Explorer) satellite project. Stephen Hawking calls Smoot's observations "the scientific discovery of the century, if not all time". The reader easily comes to identify with the author and his work -- "In the predawn darkness, not far away, fifteen years of work were sitting atop many tons of high explosives. If it blew to bits, what would I do? ... I had seen the [Delta] rocket close up, and had been aghast at how decrepit it looked, rusting here and there... Our professional life's work was on top of that thing. We didn't say a word, only silent prayers."
The author explains well the theories, predictions, discoveries, and conundrums of cosmology. The explanation of Guth's inflation theory is particularly lucid. In summarizing the startling discoveries of recent astrophysical observation, Smoot reposes in the wonder of the created order with these words: "[Steven] Weinberg muses... 'The more the universe seems comprehensible, the more it also seems pointless.' I must disagree with my old teacher. To me the universe seems quite the opposite of pointless... The more we learn, the more we see ... there is an underlying unity to the sea of matter and stars and galaxies ... we are learning that nature is as it is not because it is the chance consequence of a random series of meaningless events; quite the opposite."
