Everything we are and everything around us comes from one place and one moment: the Big Bang. Contemporary cosmology, that discipline in which astronomy coexists with quantum physics and general relativity to study the origin and early evolution of the universe, explains the emergence and distribution of celestial bodies and chemical elements. George Smoot and Keay Davidson present in this book an account of the milestones that over the 20th century transformed our understanding of the cosmos; it is also an exciting log of Smoot's own contributions— with balloons ascending into the stratosphere, Bomber aircraft adapted for scientific exploration, severe trips to Antarctica, all seasoned with rivalries between different research groups—to scrutinize in the cosmic background of microwaves, as had never been done before, in search of small irregularities—the "wrinkles in time" of the title—in the space-time structure in the early moments of the Big Bang. Perhaps the contagious passion radiating from this book comes from George Smoot's certainty that these findings were "like looking at God" because he managed to "glimpse the very moment of creation." That's why Stephen Hawking considered this to be "the scientific discovery of the century, if not of all time."
