The stars, other suns like our own, are vastly distant from us - millions of times further than the furthest of our local planets. Travelling to them, even at the fastest speeds which can now be conceived, would mean voyage-times ranging from decades to thousands of years. In The Iron Sun Adrian Berry shows how this fundamental obstacle to man's conquest of interstellar travel could be overcome. He shows how it would be both economically and technologically possible within about 250 years' time, for a spaceship to travel instantaneously in space - to disappear in one place and reappear the very next instant in another, without passing any point in between.
