First broadcast:
Wednesday 27 January 2010

Most of our universe is missing. Scientists have called the stuff they can’t find dark matter. It may not have much bearing on our everyday lives but the current theories about how the universe behaves depend on discovering the dark matter. The search for this elusive stuff is currently hotting up with new experiments about to start. Sue Nelson joins a UK group a kilometre under the ground in North Yorkshire as they put the finishing touches to their apparatus. And she learns that they have put their money on the dark matter being something called WIMPS.
