Charles Kolb of the National Endowment for the Humanities writes that Cavelos "has given us a good story and has transported the reader from science fiction to science fact and probability... There is a great deal of scientific material presented in an upbeat, non-trivialized, well-written and engaging style." However, Kolb found Cavelos' lack of direct citations to publications and expert interviews "particularly distressing" for readers wishing to verify in-line quotations or easily locate additional sources. Frederick Pratter's review in The Christian Science Monitor largely echoed Kolb's praise, stating "the scientific research presented is the mainstream of current thinking in astrophysics, cosmology, robotics, genetics, and biological adaptation. The style, as might be expected, is light and breezy, but rarely trivializes the material".
