Faster Than The Speed Of Light

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.
