Albert Einstein's theory of general relativity has revolutionised our understanding of gravity, space and time. Initially acclaimed, then forgotten, and now rediscovered, the adventure of this hundred-year-old theory has marked the scientific history of the 20th century. From its inception, a mathematical difficulty arose that could have nipped the theory in the bud: the Schwarzschild singularity. In the company of great international relativistic physicists, the viewer embarks on a discovery... see more
