Time is one of nature's greatest mysteries. In the modern world, our lives are governed by time, but what exactly is it? And what impact does time have on the planet, on life and on us? Ever since H G Wells dreamed up his famous time machine, humans have been intrigued by time travel. In this groundbreaking book, Bernard Walton, creator and producer of the accompanying series, uses his own time machine to travel back in time to bring to life the swift, dramatic events and slow but forceful changes that have shaped the world we know today. By turning centuries into seconds, we see how continents break apart and collide to create familiar mountain ranges like the Himalayas and cracks in the Earth, such as the Great Rift Valley in Africa. We explore the rhythms and cycles of life, both in a single day and over evolutionary history, of plants and animals, and learn how life has shaped entire landscapes, changing the surface of the planet forever. Bernard gives fascinating insights into man's obsession with time, how we manipulate it and use it to our advantage, and the impact that civilization has had on the Earth. Time Machine unlocks the secrets of our turbulent planet. Computer graphics and striking time-lapse images show the dramatic physical changes of the Earth and its life forms over the millions of years since time began. From dramatic changes in prehistory to the variations in the planet's landscape and environment during the last century, Time Machine is the compelling story of time on the Earth.
