The Brian Cox Wonders of the Universe programmes on Sunday nights have been brilliant. The second programme Stardust was probably the best documentary on Physics I've ever seen.

But you might have missed JimAl-Khalili on BBC4 on Monday night. He did a brilliant programme about why the sky is black at night even though the Universe is infinite in size. You should watch it! http://www.bbc.co.uk/iplayer/episode/b00yb59m/Everything_and_Nothing_Everything/
