Scientists in the past few decades have made crucial discoveries about how our cosmos evolved over the past 13.8 billion years. But there remains a critical gap in our knowledge: we still know very little about what happened in the first seconds after the Big Bang. At the Edge of Time focuses on what we have recently learned and are still striving to understand about this most essential and mysterious period of time at the beginning of cosmic history.
Taking readers into the remarkable world of cosmology, Dan Hooper describes many of the extraordinary and perplexing questions that scientists are asking about the origin and nature of our world. Hooper examines how we are using the Large Hadron Collider and other experiments to re-create the conditions of the Big Bang and test promising theories for how and why our universe came to contain so much matter and so little antimatter. We may be poised to finally discover how dark matter was formed during our universe’s first moments, and, with new telescopes, we are also lifting the veil on the era of cosmic inflation, which led to the creation of our world as we know it.
Wrestling with the mysteries surrounding the initial moments that followed the Big Bang, At the Edge of Time presents an accessible investigation of our universe and its origin.

"Essential reading for any cosmology enthusiast."Dr. Laura Nuttall, BBC Sky at Night"[An] informed introduction to 'the mysteries of our universe’s first seconds.'"Andrew Robinson, Nature"Scientists know precious little about what happened when the universe got its start: many cosmologists think space and time underwent an extremely rapid expansion called inflation. . . . Hooper takes readers on a mind-bending expedition through these questions and shows how they all connect to the beginning."Clara Moskowitz, Scientific American"If you're mystified and curious about the mysteries of the Universe . . . you won't want to miss this book."Ethan Siegel, Forbes
