A new look at the first few seconds after the Big Bang—and how research into these moments continues to revolutionize our understanding of our universe 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. Delving into the remarkable science 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.
Excerpt from Popular Lectures on Astronomy: Delivered at the Royal Observatory of Paris The publishers of the present volume, being aware that errors of a more or less important kind, must, under such circumstances, have prevailed in the original Belgian edition, and still more in the English translation, and that omissions and chasms must have required to be filled up by some person conversant with the science, and capable of writing upon it in a clear and familiar style, applied to Dr. Lardner, and induced him to revise the reported Lectures, and to add to them such topics as might appear desirable to give them increased utility. The result of this arrangement has been the present volume. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

In this insightful work on astronomy, the writer attempts to explain how much of the fundamentals of Astronomy can be obtained with the coarsest observation with the naked eye, and that the instrumental images derived from a standard globe are sufficient for understanding the instruments in an Observatory. His main aim is to impress upon the student of Astronomy that nothing is entirely beyond his reach.
