'an accessible account of gravity, black holes and the Universe ... A refreshing alternative to the received wisdom.' New Scientist 'For readers who really want to get to grips with the concepts and don't mind a few simple equations (on the level of F=ma), Narlikar's exposition is masterly, a model of clarity and illumination. And it is enlivened wtih many interesting side-lights and touches of humour ... This book is not only full of insights, it is also fun.' Werner Israel, Physics World 'This pocket-sized text on a difficult subject makes good reading (a trip home on the train!) for the general reader.' Irish Astronomical Journal ' ... a refreshing read ... rewards await those who concentrate on its contents.' Quentin Stanley, Journal of the British Astronomical Association ' ... clear and simple explanations of basic gravitational phenomena: it does not try to rush headlong into exotica, but takes time to coax the reader through orbits, motions and the fate of stars.' John D. Barrow, The Observatory
