"Radio 4 joins CERN on 10 September 2008 as scientists attempt to discover more about the origins of the Universe by recreating the aftermath of the Big Bang.
The experiment is one of the most complex and significant of modern times - and one that raises a lot of questions!"
Check out the website to find out what's on. I'll definitely be listening in to some themed drama in the afternoon, "Torchwood comes to Radio 4 in a specially-commissioned drama. Martha Jones, ex-time traveller and now working as a doctor for a UN task force, has been called to CERN. Join Captain Jack and friends in a series of strange events around the activation of the world's largest particle accelerator." Link (also available as a podcast)
