Physics and Astronomy (R0) - The Antigravity Enigma

From magic carpets to hoverboards and space drives, the human imagination has always seen antigravity as the ultimate aspirational symbol of power over nature. It featured prominently in the technologically optimistic science fiction of the mid-20th century, and remains popular with amateur theorists hoping to make a world-shaking breakthrough, and those seeking to explain UFO sightings in terms of alien technology. Yet the whole concept of antigravity is often derided by professional scientists. Is this a valid view, or are they missing something? This entertaining and thought-provoking book provides a wide-ranging survey of the whole field of antigravity, from science-fictional treatments by the likes of H. G. Wells, Isaac Asimov and Arthur C. Clarke, through speculative research by NASA, universities and the aerospace industry, to the totally different mindset of ufologists, fringe researchers and conspiracy theorists. In a world where our understanding of physics is known to be incomplete, and which has been shaken by numerous paradigm shifts in the past, can we be certain that the discovery of antigravity isn’t just around the corner?
