Ready for action at the LHC (Courtesy: BBC).

Clearly the world didn’t end earlier today when the first protons made their way around the LHC.

But what if something unexpected had happened…what if physicists (including our own Jon Cartwright) started vanishing and what if something was lurking in the accelerator tunnel…who would we turn to?

Torchwood’s Captain Jack, of course, who will be leaping from the tallest toroids later today in a special radio edition of the Dr Who spin-off set at the LHC.

You can listen to Torchwood: Lost Souls on BBC Radio 4 today at 14.15 BST and for the next seven days as a podcast.
