“Impey combines the vision of a practicing scientist with the voice of a gifted storyteller.”—Dava Sobel In this vibrant, eye-opening tour of milestones in the history of our universe, Chris Impey guides us through space and time, leading us from the familiar sights of the night sky to the dazzlingly strange aftermath of the Big Bang. What if we could look into space and see not only our place in the universe but also how we came to be here? As it happens, we can. Because it takes time for light to travel, we see more and more distant regions of the universe as they were in the successively greater past. Impey uses this concept—"look-back time"—to take us on an intergalactic tour that is simultaneously out in space and back in time. Performing a type of cosmic archaeology, Impey brilliantly describes the astronomical clues that scientists have used to solve fascinating mysteries about the origins and development of our universe. The milestones on this journey range from the nearby to the remote: we travel from the Moon, Jupiter, and the black hole at the heart of our galaxy all the way to the first star, the first ray of light, and even the strange, roiling conditions of the infant universe, an intense and volatile environment in which matter was created from pure energy. Impey gives us breathtaking visual descriptions and also explains what each landmark can reveal about the universe and its history. His lucid, wonderfully engaging scientific discussions bring us to the brink of modern cosmology and physics, illuminating such mind-bending concepts as invisible dimensions, timelessness, and multiple universes. A dynamic and unforgettable portrait of the cosmos, How It Began will reward its readers with a deeper understanding of the universe we inhabit as well as a renewed sense of wonder at its beauty and mystery.

An outsider in his own time, Jack finds himself a stranger in the distant past, then a pawn in a dark, dystopian future where rebels struggle to overturn an ancient and ruthlessly oppressive empire. Jack has an exceptional gift: a remarkable ability to absorb and memorise facts instantly and without effort. A lonely teenager, he has had little control over his life, having to leave behind friends and everything familiar, in the move to a new town, a new school, a new start. Jack misses his old life. He knows that his immediate future will not be easy – his astonishing memory has not always helped win him friends – but he can never have anticipated the incredible events that are about to befall him. Discovering what appears to be an ancient coin, Jack finds himself abruptly hurled back and then forward through time, by a technology and an intelligence beyond his control. Jack’s extraordinary memory, and his fascination with history, are to prove vital as he is thrown back across the centuries, to the early years of the Roman occupation of Britain, then forward to the heart of a vastly powerful totalitarian state. In both past and future, manipulated by opposing factions, Jack’s life is under constant threat. He will need all his ability and courage to survive. Whom can he trust? Can he save those he cares for? Will he ever return home?
