The story of an extraordinary scientific adventure - the attempt to control gravity. For centuries, the precise workings of gravity have confounded the greatest scientific minds, and the idea of controlling gravity has been seen as little more than a fanciful dream. Yet in the mid 1990s, UK defence manufacturer BAE Systems began a groundbreaking project code-named Greenglow, which set about turning science fiction into reality. On the other side of the Atlantic, Nasa was simultaneously running its own Breakthrough Propulsion Physics Project.
The story of the most elegant and powerful theory in science - Albert Einstein's general relativity. When Einstein presented his formidable theory in November 1915, it turned our understanding of gravity, space and time completely on its head. Over the last 100 years, general relativity has enabled us to trace the origins of the universe to the Big Bang and to appreciate the enormous power of black holes.
This captivating documentary from the History Channel recounts the development of iconic physicist Albert Einstein's provocative theory of general relativity. Some 200 years after the introduction of Isaac Newton's law of universal gravitation, Einstein rocked the science community with his theory, which suggests that gravity is a warping of space-time caused by the presence of matter.
