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 of this theory with a singular destiny. We discover a "curved" universe that proves to be even stranger than Einstein had envisioned, and harbours some objects - such as black holes - that still challenge today's scientists.
The core of the video is a pedagogical workshop on the Theory of Special Relativity as part of the educational process conducted by our youth leadership.
Explore how one man's relentless drive and invention of the atomic bomb changed the nature of war forever, led to the deaths of hundreds of thousands of people and unleashed mass hysteria.
Prof. Jim Al-Khalili tackles the biggest subject of all, the universe. Through a series of critical observations and experiments that revolutionised our understanding of our world Jim guides us through the greatest cosmic detective story of all.
Structural study of a tree. Light, water and air coax it out of the soil in a manner foregrounding time’s relativity to different forms of life on Earth.
Professor Jim Al-Khalili investigates the amazing science of gravity. As well sculpting our universe, gravity also affects our weight, height and even the rate at which we age.
Follow leading scientists around the world and to the edge of the universe on their quest to solve one of the greatest mysteries of the universe, the mysterious invisible “dark matter.
A documentary produced in 1979 to celebrate the centenary of the birth of Albert Einstein. Narrated and hosted by Peter Ustinov and written by Nigel Calder.
Who invented time, who invented the clock? Why 1 hour, why 60 minutes, why 60 seconds? Since prehistoric times, man has sought to measure time, to organize social and religious life, to plan food supply.
