Horizon BBC 2 Tuesday 2nd December with Professor Brian Cox.
On the same subject, article in last weeks New Scientist, 'Time on trial'.
I saw this also on BBC News website today and thought it a very interesting article. I have also copied it in case it gets removed from the web if any-one wants to read it.
