Faster Than the Speed of Light?

Last month scientists released findings which claim to have recorded particles travelling faster than the speed of light. If accurate, these findings will rock the world of science, shaking the foundations of much of what we think we understand. Now, scientists around the world are searching for answers: some are going through the experiment's processes, instruments and data with a fine-toothed comb, trying to find what is almost inevitably an error. A few are exploring the possibility that these particles can actually travel faster than the speed of light, how that might happen, and what that would mean for our current understanding of the universe.

Marcus DuSautoy is mathematics' answer to Brian Cox, and presents Faster Than the Speed of Light? for the BBC, which puts forward the important aspects of the situation in a way which is accessible to anybody with a basic grasp of science and, more importantly, an interest in the deeper workings of life, the universe and everything.

You can watch it via the BBC's iPlayer here (available until 31^st October):
