Excellent non-technical and very level headed documentary on the recent experiment at Cern which appeared to have clocked neutrinos traveling faster than the speed of light which has raised such a buzz here and wordwide..
This documentary is highly informative on many of the main issues without requiring even an O level in physics or maths.
An interesting side point from one of the possible explanations (neutrinos went through 'hyperspace/wormhole) is that if that is so, it may be possible to calculate the curvature of our universe from the difference. It wont accurate as we dont know if the universe is actually a shere, a hypersphere, or a flat(ish) brane, let alone a parabolic brane or one of the more exotic shapes.
... Anybody fancy doing some of the calculations? hehehe
.. and you don't need to understand a word of that to get a great deal from this documentary.
Highly recommended viewing for all.
