From the first landings on the moon to the implications of our cyber worlds, this unusual and intriguing book takes a provocative look at our fascination with space. Rocket Dreams is a fast-moving, fact-filled study of how all the dreams that went in to moonflight in the '60s have found new homes and mutated into new fascination with space. It is about our unquenchable desire to reach out to other worlds, physical and imaginative. From the Apollo astronauts to the military origins of the internet, and the whole phenomenon of 'virtual communities', it reveals how the ideals and longings pinned on cyberspace have evolved directly from those of the space age. Space dreams have been transformed into screen dreams, but the longing for communication with 'the other' lies at the heart of both.
The idea that the speed of light is a constant - at 186, 000 miles per second - is one of the few scientific facts that almost everyone knows. That constant - c- also appears in the most famous of all scientific equations: e=mc2- Yet over the last few years, a small group of highly reputable young physicists have suggested that the central dogma of modern physics may not be an absolute truth - light may have moved faster in the earlier life of the universe, it may still be moving at different speeds elsewhere today.
In telling the story of this heresy, and its gradual journey towards acceptance, Joao Magueijo writes as one of the three central figures in the story, introducing the reader to modern cosmology, to the implications of VSL (variable speed of light) and to the world of physicists. The initial rejection of Magueijo's ideas is beginning to give way to a reluctant acceptance that the young men may have a point - only the next few years will tell the final fate of this 'dangerous' idea.
