In Sep. 2011, an international group of scientists at Cern made one of the most astonishing statements of this generation: that they had detected particles that seemed to travel faster than the speed of light. If they turn out to be right, that will mean Albert Einstein's theory of relativity is wrong and ­travelling into the past or to a parallel universe might no longer be confined to the likes of Doctor Who. In this programme, Professor Marcus du Sautoy tries to explain to us non-boffins what it's all about and why it matters. Of course, there's always the possibility the scientists have just got it wrong.

Preview of "The Fabric of the Cosmos," a four-hour series based on the book by renowned physicist and author Brian Greene, takes us to the frontiers of physics to see how scientists are piecing together the most complete picture yet of space, time, and the universe. With each step, audiences will discover that just beneath the surface of our everyday experience lies a world we'd hardly recognize—a startling world far stranger and more wondrous than anyone expected.

The Biography of World's Most Famous Equation.
Its the story behind world's most famous equation, E = mc2.
Exactly 100 years ago, Albert Einstein grappled with the implications of his revolutionary special theory of relativity and came to a startling conclusion: mass and energy are one, related by the formula E = mc2.
