This delightfully written book takes the reader on a journey though the history of gravity, from the 16th century experiments of Galileo, through the remarkable insights of Einstein, to the recent observations of gravitational radiation from cataclysmic cosmic events: the merger of two black holes. The history of the Universe itself, from the Big Bang to the present, is traced in a way that delineates the essential role played by gravity in its evolution. The reader is afforded the option of following these stories with varying degrees of attention to technical detail. At whatever level suits ones taste, a fascinating trip is in store.
