At some point in the next two centuries, mankind will achieve the 'Giant Leap'. People will make the ultimate space voyage; they will leave our solar system and head out to the stars. This book shows why these voyages of colonisation will take place and how it will be possible to attain the tremendous speeds needed to make them well within a human lifetime. Adrian Berry's vision of the future includes many fascinating predictions; he writes with lucidity and humour, yet his ideas are always rooted in scientific fact. THE GIANT LEAP is one of the first books to explore in detail the momentous subject of interstellar flight and man's future in space.
